The present invention relates to a technique for reinforcing the ground.

In Patent Document 1, a fluid solidifying material such as mortar is filled in a surface treatment material including a planar reinforcing material and a bag body (cylindrical member) arranged in a grid pattern with respect to the planar reinforcing material.

Japanese Unexamined Patent Publication No. 2006-348481

In Patent Document 1, the planar reinforcing material and the bag body are connected by a connecting member such as a belt or a cord. At this time, the connecting member is wound around the planar reinforcing material and the bag body while penetrating the planar reinforcing material at two distant points. In this case, if the degree of binding of the connecting members is strong, the connecting members may hinder the expansion of the bag due to the filling of the fluid solidifying material. Therefore, the connecting members are connected with a margin before the fluid solidifying material is filled.

However, if the degree of binding of the coupling members is weak, the planar reinforcing material and the bag body will be misaligned when the surface treatment material before filling the fluid solidifying material is deployed under adverse conditions such as under water, water, or strong wind. There was a risk of causing.

Therefore, the present invention allows the tubular member to swell due to the filling of the fluid solidifying material, and even if it is developed under adverse conditions, the planar reinforcing material and the cylinder are provided before the filling of the fluid solidifying material. It is an object of the present invention to provide a technique capable of making it difficult for a misalignment to occur with a shaped member.

In order to solve the above problems, the surface treatment material according to the first aspect is arranged so as to intersect the planar reinforcing material on the planar reinforcing material, and a plurality of fluid solidifying materials are introduced. A first tubular body portion and a first tubular member provided at at least one intersection of the tubular member and the plurality of tubular members and holding the first tubular member and the second tubular member constituting the intersection, respectively. A holding member formed in a shape having two tubular portions is provided, and at the intersection, the first tubular member among the first tubular member and the second tubular member is the planar reinforcing material. Located on the side, the first tubular body portion extends along the outer periphery of the first tubular member and surrounds the entire outer circumference of the first tubular member, and a part thereof is fixed to the first. The second tubular body portion is fixed to the planar reinforcing material by a portion, and the second tubular body portion surrounds the entire outer peripheral surface of the second tubular member while extending along the outer periphery of the second tubular member. A part of it is connected to the first tubular body portion.

The surface treatment material according to the second aspect is the surface treatment material according to the first aspect, in which the first tubular body portion and the second tubular body portion are formed as separate bodies, and the first tubular body portion is formed. A second fixing portion for fixing the tubular body portion and the second tubular body portion is provided.

The surface treatment material according to the third aspect is the surface treatment material according to the second aspect, and the second fixing portion has the first tubular body portion and the second cylinder portion in a manner in which the seams are X-shaped. Includes an X-shaped sutured portion that is sewn to the tubular portion.

The surface treatment material according to the fourth aspect is the surface treatment material according to the second or third aspect, and is a temporary fixing portion for temporarily fixing the first cylinder portion and a part of the second cylinder portion. Is provided, and the temporary fixing portion is temporarily fixed in such a manner that the fluid solidifying material can be introduced into the tubular member and can be disengaged by receiving a force when expanding.

The surface treatment material according to the fifth aspect is the surface treatment material according to any one of the first to fourth aspects, and the first fixing portion has a seam in the extending direction of the first tubular member. Includes a linear sewn portion in which the first tubular portion and the planar reinforcing material are sewn together in a manner extending linearly along the above.

The surface treatment material according to the sixth aspect is the surface treatment material according to any one of the first to fifth aspects, and the first tubular body portion is a fluid solidifying material in the first tubular member. In the folded state before filling, the length dimension in the axial direction is set to be the same as or larger than the width dimension, and in the second tubular body portion, the fluid solidifying material is formed in the second tubular member. In the folded state before filling, the axial length dimension is set to be the same as or larger than the width dimension.

The surface treatment material according to the seventh aspect is the surface treatment material according to any one of the first to sixth aspects, and the holding member is the first tubular body portion and the said one in which the sheet material is bent. It is formed in a shape having a second tubular body portion, and further has a fastening portion that is fastened in a bent state and maintains the shape having the first tubular body portion and the second tubular body portion. ..

The surface treatment material according to the eighth aspect is the surface treatment material according to the seventh aspect, and the fastening portion includes a hook-and-loop fastener.

The rigidity reinforcing body according to the ninth aspect includes a surface layer treatment material according to any one of the first to eighth aspects, a fluid solidifying material introduced into the tubular member of the surface treatment material and solidified. To prepare for.

The breakwater according to the tenth aspect includes a rigid reinforcing body according to the ninth aspect laid on the seabed and a masonry provided on the rigid reinforcing body.

According to each aspect, since the first cylindrical body portion surrounds the entire outer circumference of the first tubular body portion, the positional deviation between the first tubular body portion and the first tubular member portion is less likely to occur. By fixing this and the first cylindrical body portion to the planar reinforcing material, misalignment between the planar reinforcing material and the first tubular member is less likely to occur. Similarly, by holding the second tubular member by the second cylindrical member connected to the first tubular body portion, the positional deviation between the first tubular member and the second tubular member is less likely to occur. From these, even if it is developed under adverse conditions, it is possible to make it difficult for misalignment to occur between the planar reinforcing material and the tubular member before filling the fluid solidifying material. It is especially effective when quick work is required, such as when deploying underwater aiming at low tide on the coast. At this time, the first cylindrical body portion extends along the outer periphery of the first tubular member, so that the first tubular body portion follows the first tubular member that swells with the filling of the fluid solidifying material. It can be inflated like a tubular member. As a result, the first tubular body portion is less likely to prevent the first tubular member from swelling. Similarly, since the second tubular member extends along the outer periphery of the second tubular member, the second tubular portion is less likely to prevent the second tubular member from swelling.

When the first cylindrical body portion and the second tubular body portion are integrally configured, at least one of them is filled with the fluid solidifying material and the first tubular member and the second tubular member try to inflate. The holding member may hinder the swelling of the cylinder. On the other hand, according to the second aspect, the first cylindrical member is less likely to prevent the first tubular member from swelling, and the second tubular member is prevented from swelling the second tubular member as much as possible. It becomes difficult to do.

According to the third aspect, since the seam can be shortened while increasing the strength of the seam by sewing in an X shape, the fluid solidifying material is filled and the first tubular member tends to swell, and The thread that fixes the first tubular body portion and the second tubular body portion is less likely to prevent the second tubular member from expanding.

According to the fourth aspect, it is possible to prevent the first cylinder portion and the second cylinder portion from fluttering after the surface treatment material is developed and before the fluid solidifying material is filled. At this time, the temporary fixing portion does not easily hinder the swelling of the tubular member when the fluid solidifying material is filled.

According to the fifth aspect, it is possible to prevent the thread fixing the first tubular body portion and the planar reinforcing member from being hindered from being filled with the fluid solidifying material and causing the first tubular member to swell roundly.

According to the sixth aspect, since the first cylindrical member holds the first tubular member in a relatively long region, misalignment is unlikely to occur between them. Similarly, since the second cylindrical member holds the second tubular member in a relatively long region, misalignment is unlikely to occur between them. From these, even if it is developed under adverse conditions, it is possible to make it difficult for misalignment to occur between the planar reinforcing material and the tubular member before filling the fluid solidifying material.

According to the seventh aspect, since the sheet material can be bent to form the tubular body portion in a state where the tubular member is superposed on the sheet material, it is possible to easily obtain a structure in which the tubular member is passed through the tubular body portion. Can be done.

According to the eighth aspect, it can be easily fastened by the hook-and-loop fastener.

{Embodiment}
Hereinafter, the surface treatment material according to the embodiment will be described. FIG. 1 is a plan view showing the surface treatment material 1 according to the embodiment. FIG. 2 is a partially enlarged perspective view of the region A of FIG. FIG. 3 is a cross-sectional view taken along line III-III of FIG. 4 to 9 are explanatory views showing how the surface treatment material 1 is manufactured.

The surface treatment material 1 includes a surface reinforcing material 2, a surface treatment tubular member 3, and a holding member 4. The surface treatment material 1 is a member that becomes a rigid reinforcing body capable of reinforcing the ground by introducing a fluid solidifying material such as mortar into the surface treatment tubular member 3 and solidifying it.

The planar reinforcing material 2 is formed of, for example, a woven fabric made of polyester fiber, nylon fiber, or the like, or a sheet material made of synthetic resin. A cylindrical member 3 for surface layer treatment is arranged on the surface reinforcing material 2. When laid on the ground as a rigid reinforcing body, the load distribution can be achieved by the planar reinforcing material 2. This makes it possible to suppress the occurrence of non-uniform settlement. The planar reinforcing material 2 may be formed of a single sheet material, or may be formed by connecting a plurality of sheet materials. The method of connecting the plurality of sheet materials is not particularly limited, and a well-known connecting method such as stitching, welding, or bonding with a hot melt resin can be adopted.

The surface layer processing cylindrical member 3 is arranged on the planar reinforcing member 2. A fluid solidifying material is introduced into the surface treatment tubular member 3. Here, the surface processing tubular member 3 includes two comb-shaped tubular members 31 and 32.

The comb-shaped tubular member 31 includes a base end-side tubular member 311 and a branch-side tubular member 312. Here, a plurality of branch-side tubular members 312 communicate with the proximal-end-side cylindrical member 311 while leaving a space in the longitudinal direction of the proximal-end-side tubular member 311. Further, here, the base end side cylindrical member 311 and the branch side tubular member 312 are orthogonal to each other. Here, a valve 5a for introducing the fluid solidifying material is provided at one end of the base end side cylindrical member 311. Therefore, when the fluid solidifying material is introduced into the proximal end-side tubular member 311 through the valve 5a, it is introduced into the plurality of branch-side tubular members 312 through the proximal end-side tubular member 311.

Similarly, the comb-shaped tubular member 32 includes a base end side cylindrical member 321 and a branch side tubular member 322. Then, a plurality of branch-side tubular members 322 communicate with the proximal end-side tubular member 321 while leaving a space in the longitudinal direction of the proximal end-side tubular member 321. Further, the base end side cylindrical member 321 and the branch side tubular member 322 are orthogonal to each other. Here, a valve 5b for introducing a fluid solidifying material is provided at one end of the base end side cylindrical member 321. Then, when the fluid solidifying material is introduced into the proximal end side cylindrical member 321 through the valve 5b, it is introduced into the plurality of branch side tubular members 322 through the proximal end side cylindrical member 321.

The base end side cylindrical member 311 and 321 and the branch side tubular member 312 and 322 are tubular woven fabrics made of, for example, polyester fiber or nylon fiber. Such a tubular woven fabric is formed, for example, by weaving wefts in a spiral shape with respect to warp threads in the length direction. At this time, the fibers, thickness, etc. of the warp and weft may be the same or different. At this time, the communication structure between the base end side cylindrical member 311 (321) and the branch side tubular member 312 (322) is formed, for example, as follows. That is, a slit is formed in the portion of the base end side cylindrical member 311 (321) that communicates with the branch side tubular member 312 (322). Then, the edge portion of the slit and the end edge portion of the branch side cylindrical member 312 (322) are joined. The means for joining the two is not particularly limited, and for example, stitching, welding, adhesion with a hot melt resin, or the like is adopted.

Here, as shown in FIG. 2, the branch-side tubular member 312, 322 exhibits a flat shape in a state before the fluid solidifying material is introduced. The same applies to the base end side cylindrical members 311 and 321. Further, the flat base end side cylindrical members 311 and 321 and the branch side tubular members 312 and 322 can be bent and deformed. Further, the planar reinforcing material 2 can also be bent and deformed. From these, the surface treatment material 1 before the introduction of the fluid solidifying material can be rolled into a roll shape (see FIG. 10) or folded (see FIG. 11). Therefore, by transporting the surface layer treatment material 1 in this state, the size at the time of transport can be reduced, and the cost for transport can be suppressed to a low level.

The two comb-shaped tubular members 31 and 32 are arranged so as to be close to each other in the portion where the valves 5a and 5b are provided, and the respective proximal end side tubular members 311 and 321 extend in directions orthogonal to each other. Has been done. As a result, the surface treatment tubular member 3 has a grid pattern on the planar reinforcing material 2. At this time, the branch-side cylindrical members 312 and 322 intersect to form the intersection 33. Here, since there are a plurality of branch-side cylindrical members 312 and 322, a plurality of intersecting portions 33 are present.

In the present specification, the tubular member constituting the intersection 33 is referred to as a first tubular member 331 and a second tubular member 332. At this time, at the intersection 33, the first cylindrical member 331 of the first cylindrical member 331 and the second tubular member 332 is located on the planar reinforcing member 2 side. That is, the one of the branch-side cylindrical members 312 and 322 located on the planar reinforcing member 2 side at the intersection 33 is referred to as the first tubular member 331, and the other is referred to as the second tubular member 332. Hereinafter, it is assumed that the first cylindrical member 331 is the branch side tubular member 312 at all the intersections 33. However, the first cylindrical member 331 may be the branch side tubular member 322. Further, there may be a case where the crossing portion 33 in which the first cylindrical member 331 is the branch side tubular member 312 and the crossing portion 33 in which the first tubular member 331 is the branch side tubular member 322 coexist.

The two comb-shaped tubular members 31 and 32 may or may not communicate with each other. When the two comb-shaped tubular members 31 and 32 communicate with each other, for example, the end of the branch-side tubular member 322 of the comb-shaped tubular member 32 communicates with the branch-side tubular member 312 of the comb-shaped tubular member 31. The configuration is conceivable. At this time, the ends of all the branch-side tubular members 322 may communicate with one branch-side tubular member 312, or may be divided into a plurality of branch-side tubular members 312 and communicate with each other. Further, for example, it is conceivable that the base end side cylindrical members 311 and 321 are communicated with each other at one end thereof.

The holding member 4 is provided at at least one intersection 33. Here, it is assumed that the holding member 4 is provided at all the intersections 33. Therefore, the surface treatment material 1 includes the same number of holding members 4 as the plurality of intersections 33. Each holding member 4 is formed in a shape having a first tubular body portion 41 and a second tubular body portion 42. In the following, as shown in FIG. 4, the holding member 4 before holding the first cylindrical member 331 and the second tubular member 332 may be referred to as a holding member 4B.

The first cylindrical body portion 41 holds the first tubular member 331. The first cylindrical body portion 41 extends along the outer circumference of the first tubular member 331 and surrounds the entire outer circumference of the first tubular member 331. At this time, it is preferable that the peripheral length on the inner peripheral surface of the first cylindrical body portion 41 is set to be about the same as the peripheral length on the outer peripheral surface of the first tubular member 331 (for example, the deviation is within 5%). As a result, the outer peripheral surface of the first tubular member 331 is covered over the entire circumference as compared with the case where the peripheral length on the inner peripheral surface of the first cylindrical body portion 41 is too larger than the peripheral length on the outer peripheral surface of the first tubular member 331. The inner peripheral surface of the first cylindrical body portion 41 is more likely to be in close contact with each other, and thus misalignment is less likely to occur between them. Further, as compared with the case where the peripheral length on the inner peripheral surface of the first tubular body portion 41 is too smaller than the peripheral length on the outer peripheral surface of the first tubular member 331, the fluid solidifying material is filled and the first tubular member 331 is filled. The first cylinder portion 41 is less likely to prevent the swelling. A part of the first tubular body portion 41 is fixed to the planar reinforcing member 2 by the first fixing portion 43.

As the first fixing portion 43, a linear suture portion 431 is provided here. The linear stitched portion 431 has a first tubular body portion 41 in such a manner that the seam extends linearly along the extending direction of the first tubular member 331, that is, along the axial direction of the first tubular body portion 41. And the planar reinforcing material 2 are sewn together. At this time, the linear suture portion 431 is in a folded state before the first tubular body portion 41 is filled with the fluid solidifying material in the first tubular body portion 331, and is in the center in the width direction of the first tubular body portion 41. It is provided.

The second cylindrical body portion 42 holds the second tubular member 332. The second cylindrical body portion 42 extends along the outer circumference of the second tubular member 332 and surrounds the entire outer circumference of the second tubular member 332. At this time, it is preferable that the peripheral length on the inner peripheral surface of the second cylindrical body portion 42 is set to be about the same as the peripheral length on the outer peripheral surface of the second tubular member 332 (for example, the deviation is within 5%). As a result, the outer peripheral surface of the second tubular member 332 is covered over the entire circumference as compared with the case where the peripheral length on the inner peripheral surface of the second cylindrical body portion 42 is too larger than the peripheral length on the outer peripheral surface of the second tubular member 332. The inner peripheral surface of the second cylindrical body portion 42 is more likely to be in close contact with each other, and thus misalignment is less likely to occur between them. Further, as compared with the case where the peripheral length on the inner peripheral surface of the second tubular body portion 42 is too smaller than the peripheral length on the outer peripheral surface of the second tubular member 332, the fluid solidifying material is filled and the second tubular member 332 is filled. The second cylinder portion 42 is less likely to prevent the swelling. A part of the second tubular body portion 42 is connected to the first tubular body portion 41.

Here, the first tubular body portion 41 and the second tubular body portion 42 are formed as separate bodies. A second fixing portion 44 for fixing the first cylinder portion 41 and the second cylinder portion 42 is provided. That is, here, the second tubular body portion 42 is connected to the first tubular body portion 41 via the second fixing portion 44.

As the second fixing portion 44, an X-shaped suture portion 441 is provided here. The X-shaped stitched portion 441 sews the first tubular body portion 41 and the second tubular body portion 42 in such a manner that the seams are X-shaped. The X-shaped suture portion 441 is provided so that the holding member 4 is located near the center of the intersection 33, for example, in a state where the first tubular member 331 and the second tubular member 332 are held.

Here, one of the two seams forming the X-shaped stitched portion 441 extends along the axial direction of the first tubular body portion 41, and the other seam 4412 is the first tubular body portion 41. It extends along the axial direction of. However, the extending directions of the seams 4411 and 4412 are not limited to those described above. For example, it is conceivable that the extending direction of the seams 4411 and 4412 intersects the axial direction of the first tubular body portion 41 and the axial direction of the second tubular body portion 42.

The first cylindrical body portion 41 is in a folded state before the first tubular member 331 is filled with the fluid solidifying material, and the axial length dimension is set to be the same as or larger than the width dimension. .. As a result, the axial length of the first cylindrical body portion 41 is set to be relatively long, so that the first tubular body portion 41 holds the first tubular member 331 before filling with the fluid solidifying material. It is possible to prevent the positional deviation between the 1-cylindrical body portion 41 and the 1st tubular member 331 from occurring. However, the first cylindrical body portion 41 may be set to have a length dimension in the axial direction smaller than the width dimension in a folded state before the fluid solidifying material is filled in the first tubular member 331.

Similarly, the second tubular body portion 42 is set to have an axial length dimension equal to or larger than the width dimension in a folded state before the second tubular member 332 is filled with the fluid solidifying material. Has been done. As a result, the axial length of the second cylindrical body portion 42 is set to be relatively long, so that the second tubular body portion 42 holds the second tubular member 332 before being filled with the fluid solidifying material. It is possible to prevent the misalignment between the two-cylindrical body portion 42 and the second tubular member 332 from occurring. However, the second cylindrical body portion 42 may be set to have a length dimension in the axial direction smaller than the width dimension in a folded state before the second tubular member 332 is filled with the fluid solidifying material.

Further, here, the first cylindrical body portion 41 is set to have the same axial length dimension as the width dimension in a folded state before the first tubular member 331 is filled with the fluid solidifying material. There is. Therefore, the first cylindrical body portion 41 has a square shape in a plan view in a folded state before the fluid solidifying material is filled in the first tubular member 331. Further, here, the second cylindrical body portion 42 is set to have the same axial length dimension as the width dimension in a folded state before the second tubular member 332 is filled with the fluid solidifying material. There is. Therefore, the second cylindrical body portion 42 has a square shape in a plan view in a folded state before the second tubular member 332 is filled with the fluid solidifying material. At this time, the first cylindrical body portion 41 and the second tubular body portion 42 have the same size in the folded state before the first tubular member 331 and the second tubular member 332 are filled with the fluid solidifying material. It is formed on a tatami mat.

The holding member 4 is formed in a shape in which the sheet material 45 is bent to have a first tubular body portion 41 and a second tubular body portion 42. Here, since the first tubular body portion 41 and the second tubular body portion 42 are separate bodies, the sheet material 45 includes the first sheet material 451 constituting the first tubular body portion 41 and the first sheet material 451. Is separately provided and has a second sheet material 452 constituting the second tubular body portion 42. The first sheet material 451 and the second sheet material 452 are fixed by the second fixing portion 44. The sheet material 45 is, for example, a woven fabric made of polyester fiber, nylon fiber, or the like, or a sheet material made of synthetic resin. The sheet material 45 may be formed of the same material as the sheet material constituting the planar reinforcing material 2, or may be formed of a different material.

The holding member 4 further includes a fastening portion 46 in which the sheet material 45 is fastened in a bent state to maintain the shape having the first tubular body portion 41 and the second tubular body portion 42. The fastening portion 46 includes a first fastening portion 461 for maintaining the first tubular body portion 41 and a second fastening portion 462 for maintaining the second tubular body portion 42. The first fastening portion 461 is provided on the first sheet material 451. The second fastening portion 462 is provided on the second sheet material 452.

Here, a hook-and-loop fastener is adopted as the fastening portion 46. Specifically, as the first fastening portion 461, the surface fastener 4611 provided at one end of the first sheet material 451 and the surface fastener 4612 provided at the other end of the first sheet material 451 and capable of adhering to the surface fastener 4611. And are provided. Similarly, as the second fastening portion 462, a surface fastener 4621 provided at one end of the second sheet material 452 and a surface fastener 4622 provided at the other end of the second sheet material 452 and capable of adhering to the surface fastener 4621 are provided. Has been done. Here, the hook-and-loop fastener 4611 and the hook-and-loop fastener 4612 may be a combination in which one is a hook type and the other is a loop type, or both are mixed types in which hooks and loops are mixed. May be good. The same applies to the hook-and-loop fastener 4621 and the hook-and-loop fastener 4622. Further, here, one of the hook-and-loop fasteners 4611 and the hook-and-loop fasteners 4612 is provided on one main surface of the first sheet material 451 and the other is provided on the other main surface of the first sheet material, but both are first. 1 It may be provided on one main surface of the sheet material 451. The same applies to the hook-and-loop fastener 4621 and the hook-and-loop fastener 4622.

Further, here, apart from the second fixing portion 44, a temporary fixing portion 47 for temporarily fixing a part of the first tubular body portion 41 and the second tubular body portion 42 is provided (see FIG. 9). The temporary fixing portion 47 is temporarily fixed in such a manner that the fluid solidifying material is introduced into the first tubular member 331 and the second tubular member 332 and can be disengaged by receiving a force when expanding. By providing the temporary fixing portion 47, it is possible to prevent the first tubular body portion 41 and the second tubular body portion 42 from fluttering in the state before the fluid solidifying material is introduced. Further, even if a twisting force is applied to the first tubular body portion 41 and the second tubular body portion 42 by forming the temporary fixing portion 47, the force is less likely to reach the second fixed portion 44. As a result, it is possible to prevent the second fixing portion 44 from canceling the fixed state of the first cylinder portion 41 and the second cylinder portion 42.

More specifically, here, as the temporary fixing portion 47, a punctate hot melt resin fixing portion 471 in which the hot melt resin is spotted is formed. Specifically, the point-shaped hot melt resin fixing portion 471 is interposed between the outer surface of the first tubular body portion 41 and the outer surface of the second tubular body portion 42 to join the two. Since the adhesive region of the punctate hot melt resin fixing portion 471 is relatively narrow, the punctate hot melt resin fixing portion 471 can be fixed with a relatively weak force when the fluid solidifying material is introduced into the first tubular member 331 and the second tubular member 332 and swells. It can be canceled.

The punctate hot melt resin fixing portion 471 is provided at the widthwise end portion of the second tubular body portion 42. In the example shown in FIG. 9, one point-shaped hot melt resin fixing portion 471 is provided at the center in the axial direction at each end portion in the width direction of the second tubular body portion 42. However, the position, number, size, etc. of the point-shaped hot melt resin fixing portions 471 are not particularly limited, and may be appropriately set according to the location where fluttering is desired to be suppressed, the adhesive strength, and the like. For example, the point-shaped hot melt resin fixing portion 471 may be provided at the four corners of the second tubular body portion 42. Further, for example, a plurality of second tubular body portions 42 may be provided at each end portion in the width direction so as to be arranged along the axial direction.

<Manufacturing method>
The method for manufacturing the surface treatment material 1 will be described with reference to FIGS. 4 to 9.

First, the holding member 4B is prepared. Specifically, the central portion of the one-sided region in the longitudinal direction of the first sheet material 451 and the central portion of the one-sided region in the longitudinal direction of the second sheet material 452 are sewn in an X-shape to be sewn in an X-shape. Part 441 is formed. As a result, the first sheet material 451 and the second sheet material 452 are fixed. Further, a hook-and-loop fastener 4611 is provided at one end in the longitudinal direction of the first sheet material 451 and a hook-and-loop fastener 4612 is provided at the other end in the longitudinal direction of the first sheet material 451. Similarly, a hook-and-loop fastener 4621 is provided at one end in the longitudinal direction of the second sheet material 452, and a hook-and-loop fastener 4622 is provided at the other end in the longitudinal direction of the second sheet material 452. From the above, the holding member 4B before being fixed to the planar reinforcing material 2 is completed. After that, the remaining holding member 4B is manufactured as much as it is fixed to the planar reinforcing material 2.

Next, the holding member 4B is fixed at a position where the intersection 33 is arranged in the planar reinforcing member 2. Here, the holding member 4B is fixed at the positions of all the intersections 33. Specifically, the central portion of the other side region portion (the region portion on the side opposite to the side where the X-shaped suture portion 441 is provided) in the longitudinal direction of the first sheet material 451 is arranged in the arrangement direction of the first tubular member 331. A linear suture portion 431 is formed by stitching linearly with the planar reinforcing material 2 along (the lateral direction of the first sheet material 451). As a result, the first sheet material 451 and the planar reinforcing material 2 are fixed, and thus the holding member 4B and the planar reinforcing material 2 are fixed. After that, the holding member 4B is similarly fixed at the position of the remaining intersection 33. By fixing the holding member 4B at the position of the predetermined intersection 33, an intermediate product of the surface treatment material capable of fixing the first cylindrical member 331 and the second tubular member 332 at the predetermined intersection 33 is completed. Will be.

Next, the holding member 4B is made to hold the first cylindrical member 331. Specifically, as shown in FIG. 4, the first tubular member 331 is overlapped with the other side region in the longitudinal direction of the first sheet material 451 and linearly sewn in the vicinity of the central portion in the width direction of the first tubular member 331. It is extended according to the part 431. In this state, as shown in FIG. 5, the one-sided region portion in the longitudinal direction of the first sheet material 451 is bent and stacked on the first cylindrical member 331. Then, the hook-and-loop fastener 4611 and the hook-and-loop fastener 4612 are fastened to maintain the first sheet material 451 in a state where the first tubular body portion 41 is formed.

Next, the holding member 4B is made to hold the second cylindrical member 332. Specifically, as shown in FIG. 6, the second tubular member 332 is overlapped with the one-sided region in the longitudinal direction of the second sheet material 452, and the vicinity of the central portion in the width direction of the second tubular member 332 is X-shaped. Align with the sutured portion 441. In this state, as shown in FIG. 7, the other side region portion in the longitudinal direction of the second sheet material 452 is bent and stacked on the second tubular member 332. Then, the hook-and-loop fastener 4621 and the hook-and-loop fastener 4622 are fastened to maintain the second sheet material 452 in a state where the second tubular body portion 42 is formed.

As described above, the holding member 4 holds the first cylindrical member 331 and the second tubular member 332 at the position of the intersection 33 on the planar reinforcing member 2.

Next, the first tubular body portion 41 and the second tubular body portion 42 are temporarily fixed by the temporary fixing portion 47. Specifically, the hot melt resin is spotted between the outer surface of the first tubular body portion 41 and the outer surface of the second tubular body portion 42 to form the punctate hot melt resin fixing portion 471. For example, as shown in FIG. 9, the hot melt resin is spotted on the outer surface of the first tubular body portion 41 in a state where the second tubular body portion 42 and the second tubular member 332 held by the second tubular body portion 42 are turned over. 2 The tubular body portion 42 is returned to its original position and adhered.

By temporarily fixing the first tubular body portion 41 and the second tubular body portion 42 by the temporary fixing portion 47, the surface layer processing material 1 is completed.

<Reinforcement method>
Next, a method of reinforcing the ground 8 using the surface treatment material 1 will be described with reference to FIGS. 10 to 13. 10 to 13 are explanatory views showing how the surface treatment material 1 is used to reinforce the ground 8.

After being manufactured in a factory, for example, the surface treatment material 1 is rolled into a roll or folded and transported to a construction site in a compact state. Then, at the construction site, as shown in FIGS. 10 and 11, the product is unfolded from a rolled or folded state. In the example shown in FIG. 11, it is folded in a zigzag shape, but it may be folded in another shape. However, if it is folded in a zigzag shape, it can be unfolded by pulling one end of the surface treatment material 1, so that the unfolding work becomes easy.

Although the surface treatment material 1 is described here as being developed on the ground surface 81 in the ground 8, this is not essential. For example, it may be deployed on the water, underwater, or on the seabed 81. Further, in the examples shown in FIGS. 10 and 11, in the ground 8, the laying target area on the ground surface 81 and its surroundings are uniformly flat, but this is not an essential configuration. In the ground 8, the area to be laid on the ground surface 81 may be recessed with respect to the surrounding area. It is conceivable that the dent is, for example, a dent formed according to the surface treatment material 1.

After the surface treatment material 1 is developed, the fluid solidifying material is next introduced into the surface treatment tubular member 3. Here, the fluid solidifying material is introduced into the surface treatment tubular member 3 through the valves 5a and 5b. At this time, the fluid solidifying material may be introduced from the comb-shaped tubular member 31, or the fluid solidifying material may be introduced from the comb-shaped tubular member 32, or the fluid solidifying material may be introduced into both at the same time. May be good. It is preferable that the fluid solidifying material is first introduced into the first tubular member 331 at the intersection 33.

As shown in FIG. 12, the rigid reinforcing body 7 is formed by solidifying the fluid solidifying material 6 introduced into the surface treatment tubular member 3. Then, by laying the rigid reinforcing body 7 on the ground surface 81 in the ground 8, the reinforcing structure of the ground is formed.

In this ground reinforcement structure, it is conceivable to spread crushed stone or the like on the rigid reinforcing body 7 and perform masonry or the like as a series of finishing steps. The finishing material 9 is not particularly limited to crushed stone, earth and sand, concrete and the like. In the example shown in FIG. 13, the masonry 91 is performed as the finishing material 9.

When the surface treatment material 1 is deployed off the coast at the seabed 81, it is possible to form a breakwater offshore by introducing the fluid solidifying material 6 and applying masonry 91 as a finish.

<Effects, etc.>
According to the surface treatment material 1 configured as described above and the ground reinforcement structure using the same, the first cylinder portion 41 surrounds the entire outer periphery of the first tubular member 331, so that the first cylinder body Positional deviation between the portion 41 and the first tubular member 331 is less likely to occur. This and the fact that the first cylindrical body portion 41 is fixed to the planar reinforcing member 2 makes it difficult for misalignment to occur between the planar reinforcing member 2 and the first tubular member 331. Similarly, by holding the second cylindrical member 332 by the second cylindrical member 42 connected to the first cylindrical body portion 41, the positional deviation between the first tubular member 331 and the second tubular member 332 is caused. It is less likely to occur. From these, even if it is developed under adverse conditions, it is difficult to cause a positional shift between the planar reinforcing material 2 and the first tubular member 331 and the second tubular member 332 before filling the fluid solidifying material. Can be done. At this time, since the first cylindrical body portion 41 extends along the outer periphery of the first tubular member 331, the first cylindrical body follows the first tubular member 331 that swells with the filling of the fluid solidifying material. The portion 41 can be inflated in the same manner as the first tubular member 331. As a result, the first cylindrical body portion 41 is less likely to prevent the first tubular member 331 from swelling. Similarly, since the second tubular member 42 extends along the outer periphery of the second tubular member 332, the second tubular member 42 is less likely to prevent the second tubular member 332 from swelling.

Further, when the first cylindrical body portion 41 and the second tubular body portion 42 are integrally configured, the fluid solidifying material is filled and the first tubular body portion 331 and the second tubular member 332 try to inflate. At that time, the holding member 4 may hinder at least one of the bulges. On the other hand, according to the above aspect, the first cylindrical member 41 is less likely to prevent the first tubular member 331 from swelling, and the second tubular member 42 prevents the second tubular member 332 from swelling. It will be as difficult to inhibit as possible.

When the separate first cylinder portion 41 and the second cylinder portion 42 are sewn and fixed, the fluid solidifying material is filled and the first cylinder member 331 and the second cylinder member 332 are formed. When trying to swell, the seam may interfere with at least one bulge. On the other hand, according to the above aspect, since the seam can be shortened while increasing the strength of the seam by sewing in an X shape, the fluid solidifying material is filled and the first tubular member 331 tends to swell. This and the fact that the second tubular member 332 tries to swell is less likely to be hindered by the thread that secures the first tubular body portion 41 and the second tubular body portion 42 as much as possible.

Further, by providing the temporary fixing portion 47, it is possible to prevent the first tubular body portion 41 and the second tubular body portion 42 from fluttering before the fluid solidifying material is filled even when the surface layer treatment material 1 is deployed. can. Further, by weakening the fixing force of the temporary fixing portion 47, the temporary fixing portion 47 is less likely to hinder the swelling of the first tubular member 331 and the second tubular member 332 when the fluid solidifying material is filled.

Further, since the linear suture portion 431 is provided as the first fixing portion 43, the first tubular body portion 41 and the planar reinforcing material 2 are filled with the fluid solidifying material so that the first tubular member 331 swells in a round shape. It is possible to prevent the thread that fixes and from being obstructed.

Further, since the first cylindrical member 41 holds the first tubular member 331 in a relatively long region, misalignment is unlikely to occur between them. Similarly, since the second cylindrical member 42 holds the second tubular member 332 in a relatively long region, misalignment is unlikely to occur between them. From these, even if it is developed under adverse conditions, it is difficult to cause a positional shift between the planar reinforcing material 2 and the first tubular member 331 and the second tubular member 332 before filling the fluid solidifying material. Can be done.

Further, since the sheet material 45 can be bent in a state where the first cylindrical member 331 and the second tubular member 332 are superposed on the sheet material 45 to form the first cylindrical body portion 41 and the second tubular body portion 42. It is possible to easily obtain a structure in which the tubular members 331 and 332 are passed through the tubular portions 41 and 42.

Further, since the hook-and-loop fastener is adopted as the fastening portion 46, it can be easily fastened by the hook-and-loop fastener.

{Modification example}
Further, in the embodiment, the holding member 4 has been described as being formed by bending the sheet material 45, but this is not an essential configuration. Each of the tubular portions 41 and 42 in the holding member 4 may be formed in a cylindrical shape from the beginning. In this case, it is conceivable that the cylindrical body portions 41 and 42 are made of a tubular woven fabric, for example, like the tubular members 331 and 332.

Further, in the embodiment, it has been described that the first tubular body portion 41 and the second tubular body portion 42 are formed as separate bodies, but this is not an essential configuration. The first tubular body portion 41 and the second tubular body portion 42 may be formed as one. For example, it is conceivable that the sheet material 45 is formed of a single sheet. In this case, the sheet material 45 may be formed in an L-shape or a T-shape in a state before being bent.

Here, in the embodiment, by adopting the hook-and-loop fastener as the fastening portion 46, the state can be easily and reversibly changed between the state in which the sheet material 45 is fastened in the bent state and the state in which the fastened state is released. It is possible. If the fastening portion 46 is provided so as to be able to release the fastening state as in this case, for example, dismantling becomes easy when removing the surface layer treatment material 1 in which the fluid solidifying material is introduced.

As an example of the fastening portion 46 formed so that the state can be reversibly changed between the state in which the sheet material 45 is fastened in the bent state and the state in which the fastened state is released, the above-mentioned surface fastener is used. Other than that, for example, a button, a slider type fastener, or the like can be considered. Similar to the hook-and-loop fastener, these use a fixing member different from the sheet material 45. However, without using a fixing member different from the sheet material 45, it is also possible to form a fastening portion whose state can be changed between the state in which the sheet material 45 is fastened in a bent state and the state in which the fastened state is released. Conceivable. In this case, for example, it is conceivable that a concave portion and a convex portion that are hooked on each other are provided in a part of the sheet material 45.

However, even when the holding member 4 is formed by bending the sheet material 45, the fastening portion 46 is reversibly between the state in which the sheet material 45 is held in the bent state and the state in which the fastened state is released. Being able to change the state is not an essential configuration. In this case, the fastening portion 46 may be composed of, for example, a double-sided adhesive tape, an adhesive, welding, sewing, or the like.

Further, although it has been described that the linear suture portion 431 is provided as the first fixing portion 43, this is not an essential configuration. For example, the first fixing portion 43 may be sewn into another shape such as an X shape. Further, the first fixing portion 43 may be composed of a double-sided adhesive tape, an adhesive, welding, a fastener or the like. Further, the first fixing portion 43 may use a plurality of fixing means in combination.

Further, although it has been described that the X-shaped suture portion 441 is provided as the second fixing portion 44, this is not an essential configuration. For example, the second fixing portion 44 may be sewn into another shape such as a linear shape. Further, the second fixing portion 44 may be composed of a double-sided adhesive tape, an adhesive, welding, a fastener or the like. Further, the second fixing portion 44 may use a plurality of fixing means in combination.

Further, although it has been described that the fluid solidifying material is introduced into the surface layer treatment material 1 and used, this is not an essential configuration. For example, a fluid such as a liquid such as water or a gas such as air may be filled in the surface treatment material 1. In this case, the surface treatment tubular member 3 may be formed in a liquidtight structure or an airtight structure.

Further, although it has been described that the temporary fixing portion 47 is provided in the embodiment, this is not an essential configuration, and the temporary fixing portion 47 may be omitted. Further, even when the temporary fixing portion 47 is provided, it is not an essential configuration that the punctate hot melt resin fixing portion 471 is provided as the temporary fixing portion 47. The temporary fixing portion 47 fixes the first cylinder portion 41 and the second cylinder portion 42 with a relatively weak force when the fluid solidifying material is introduced into the first cylinder portion 41 and the second cylinder portion 42. It suffices if the temporary fixing portion 47 can be released, and for example, an adhesive tape, another adhesive, an engaging means, or the like may be adopted as the temporary fixing portion 47.

It should be noted that the configurations described in the above-described embodiment and each modification can be appropriately combined as long as they do not conflict with each other.

Although the present invention has been described in detail as described above, the above description is an example in all aspects, and the present invention is not limited thereto. It is understood that innumerable variations not illustrated can be assumed without departing from the scope of the present invention.
