  Conventionally, in the construction of civil engineering structures such as revetments and retaining walls, as shown in JP-A-5-33346, as a construction material for a civil engineering structure, a wall-shaped material for a box-shaped civil engineering structure in which a housing space opens upward is used. Attach one end of the wall material anchor to the other end of the wall material anchor, and prepare a plurality of friction force increasing means to increase the friction force. In some cases, the wall material anchors are arranged while being sequentially arranged, the wall surface material anchors are disposed substantially horizontally, and the wall surface material anchors and the frictional force increasing means are embedded with earth or sand. In this structure, not only can a strong civil engineering structure be constructed from the construction material for each civil engineering structure, but also a vegetation soil is secured in the accommodation space for the wall material for each civil engineering structure, and each wall material for each civil engineering structure is provided. It is possible to provide a civil engineering structure that has both a strong and natural environment.
  Further, as a preferred example of the wall material anchor, a shaft-like portion that extends substantially straight and whose one end is an attachment end for attaching the wall material for civil engineering construction, and the other end of the shaft-like portion are provided. A thing provided with the curved part which curves and partitions annular space is proposed. In this structure, the curved portion is held so as to be able to move with respect to the backing material filled behind the wall material for the civil engineering structure, or on the shaft-like portion with the plate surface facing the moving direction. It will function as a stopper for the plate-like member (engaged with the backing material), and the movement resistance of the wall material for the civil engineering structure can be obtained.
[0003]
[Problems to be solved by the invention]
  However, as shown in FIG. 14, a box-like (rectangular) shape is used as the wall surface material 102 for the civil engineering structure in the construction material 101 for the civil engineering structure, and the wall materials 102 for the civil engineering structures are adjacent to each other. In the part (place) S where the surface of the civil engineering structure 103 to be formed (the front wall surface of the wall material for the civil engineering structure) must be curved outward, the earth and sand 104 spills out behind the wall material 102 for the civil engineering structure. In order to avoid such a situation, the surface of the civil engineering structure 103 is changed by changing the arrangement angle of the adjacent wall surfaces 102 for the civil engineering structure while contacting the side surfaces of both rear end portions of the adjacent wall surface material 102 for the civil engineering structure. It must be curved approximately, in which it follows between the adjacent civil engineering wall surfaces 102 from the rear end of the civil engineering wall material 102 toward the front. Is a gap 105 is formed to open gradually, the gap 105 is inevitably as deep across the longitudinal general direction of the civil engineering construction for the wall member 102. For this reason, as described above, in the portion (place) S where the curved surface that swells outward must be formed as the surface of the civil engineering structure 103, the deep gap 105 is conspicuous and the user feels uncomfortable. I don't get it. Even if the gap 105 is filled with earth and sand 104 in order to eliminate the gap 105, the filled earth and sand 104 is likely to spill out, which is not a fundamental solution.
  In addition, in FIG. 14, the code | symbol 106 shows the accommodation space in the wall material for civil engineering structures, and the code | symbol 107 shows the accommodation space which the wall material for civil engineering structures forms adjacent.
  On the other hand, with respect to the preferred anchor for wall material described above, the curved portion and the shaft-shaped portion are maintained in order to maintain the function as a stopper after the curved portion is curved so as to partition the annular space. In the manufacture of the anchor for wall surface material, holding processing work such as welding work on the curved portion is indispensable.

It has a pair of side wall part 2c which connects an edge part, and the bottom wall part 2d which covers the accommodation space 4 which the front wall part 2a, the rear wall part 2b, and a pair of side wall part 2c partition in the lower part. The container 2 is curved so as to swell outward from the front wall portion 2a to the side wall portion 2c and from the rear wall portion 2b to the side wall portion 2c, and each pair of side wall portions 2c has a laterally outward central portion laterally outward. Is curved in a circular arc shape so as to swell toward the surface (curved in a semicircular shape in plan view), and the bulge amount (projection amount) is made equal throughout the height direction (vertical direction in FIG. 1). ing. For this reason, as for the container 2, the length L (refer FIG. 3) of the width direction is made constant over the whole height direction.
  Specifically, in the present embodiment, the storage container 2 is made of concrete and has a height of 20 to 30 cm, a width of 20 to 30 cm, a weight of about 30 to 50 kg, and a major axis of the storage container 2 of 35 to 45 cm. It is preferable from the viewpoints of workability, workability, and the like that the short diameter of the storage container 2 is 20 to 30 cm and the depth of the storage container 2 is 15 to 25 cm.
[0016]
  As shown in FIG. 1, the accommodation container 2 is formed with an attachment hole 5 and a drain hole 6 in the present embodiment. The attachment hole 5 is formed in the rear wall 2 b of the storage container 2, and the attachment hole 5 penetrates to the storage space 4 of the storage container 2. The drain hole 6 is formed in the bottom wall portion 2d, and the inside of the accommodation space 4 and the outside communicate with each other through the drain hole 6 as well.
[0017]
  The anchor 3 is connected to the container 2 as shown in FIGS. As shown in FIGS. 4 and 5, the anchor 3 includes a shaft-like portion 7 and a curled portion 8 as a curved portion in order to prevent movement (sliding) when the container 2 is used (in a stacked state). And a washer 9 as a plate-like member. The shaft portion 7 and the curled portion 8 are formed using a linear material, and the linear material is selected in consideration of strength, corrosion, workability, and the like. For this reason, as a linear material, an iron wire, a reinforcing bar, a pipe, etc. are preferable, and what gave them plating processing, such as zinc aluminum alloy plating, is more preferable.
[0018]
  As shown in FIG. 4, the shaft-like portion 7 extends straight in a relatively long state (for example, about 0.5 to 1.5 m), and one end portion of the anchor 3 (the left end portion in FIG. 4). ), A threaded portion 3a is formed, and a projecting portion 3b as a stopper is formed on the axially inner side of the shaft-shaped portion 7 from the threaded portion 3a. As shown in FIG. 4, when connecting the one end of the shaft-like portion 7 and the container 2, one end of the shaft-like portion 7 is inserted into the mounting hole 5, and the screw portion 3 a of the shaft-like portion 7 is inserted. By screwing the nut 30, the nut 30 and the protruding portion 3 b sandwich the rear wall portion 2 b through the washer 31.
[0019]
  As shown in FIGS. 4 and 5, the curled portion 8 is formed by winding the other end portion of the shaft-like portion 7 of the anchor 3 in a curl shape. A circular hole having an inner diameter of about 30 mm is formed in the curled portion 8, and after the formation of the hole, the other end portion (curved terminal portion) of the anchor 3 is welded as a winding portion 11. It is simply wound around the shaft-like portion 7 without any problems. In this case, the curled portion 8 is formed so as to swell on both sides with a symmetrical shape with respect to the axial center of the shaft-shaped portion 7, and the winding portion 11 is arranged on the outer peripheral side of the curving start portion 12 of the curled portion 8. Are arranged to engage with each other. In particular, in the present embodiment, the winding portion 11 is configured to simply wind in a substantially U shape so as to sandwich the shaft-like portion 7 in cooperation with the bending end portion 13 from the viewpoint of ease of processing and the like. As long as the winding part 11 does not engage with the bending start part 12 of the curled part 8, the winding part 11 is guided by the shaft-like part 7 and can move in the axial direction of the shaft-like part 7. Therefore, when an external force is applied to the winding portion 11 toward the curled portion 8, the winding portion 11 is always engaged with the bending start portion 12 of the curled portion 8 based on the guiding effect of the winding portion 11 and the shaft-like portion 7. The movement is restricted by contact (contact) (see FIGS. 4 and 5). Of course, from the viewpoint of enhancing the guiding and holding effect between the shaft-like portion 7 and the winding portion 11, the winding portion 11 may be wound around the shaft-like portion 7 a plurality of times (so-called coiled).
[0020]
  The washer 9 is held by the shaft-like portion 7 so that its plate surface is directed in the extending direction of the shaft-like portion 7. The washer 9 has a square shape with a side of about 50 mm and a thickness of about 3 mm, and an insertion hole 14 is formed at the center thereof. The shaft-like portion 7 is inserted through the insertion hole 14 of the washer 9, and the washer 9 can move the shaft-like portion 7, while the movement of the washer 9 is restricted by the curled portion 8. In this case, when an external force is applied to the curled portion 8 via the washer 9, the winding portion 11 is engaged with the bending start portion 12 in the curled portion 8 so that the movement is restricted. The curl portion 8 is effective as a stopper for the washer 9 even if the shaft-like portion 7 is not welded unless the ring having a size corresponding to the portion 8 is crushed and moved. Will work.
[0021]
  Next, a method of using the construction material for civil engineering structures (construction method of revetment) and a revetment constructed by the method of use will be described.
[0022]
  In the construction of the revetment 15, a large number of construction materials 1 for civil engineering structures are carried to each construction position along the current shore by a crane or the like via a transport tool (not shown). At this time, since the anchor 3 is relatively long, it becomes easy to bundle a large number of construction materials 1 for civil engineering structures, and the holes in the curled portion 8 can be used as hook holes. Therefore, handling and transportation can be facilitated.
[0023]
  When a large number of construction materials 1 for a civil engineering structure are conveyed to the construction position, the construction material 1 for a civil engineering structure directs the container 2 toward the river and extends in the shore direction (as shown in FIGS. 1 and 2). While being arranged adjacent to each other in the direction perpendicular to the paper surface in FIG. 1, they are sequentially stacked in a staircase pattern along the shore gradient or with a necessary gradient.
  At this time, since the length L in the width direction of each storage container 2 is constant over the entire height direction, a protective wall is formed simply by stacking them while arranging them adjacent to each other. No padding stones are packed between the two. As the storage containers 2 are stacked, the storage space 4 in each storage container 2 is appropriately filled with stuffing stones 25, vegetation soil 26, and the like, as shown in FIG. They are supposed to secure the nest of fish and aquatic organisms, and the growth environment of plants.
  Further, in the construction of the construction materials 1 for each civil engineering structure, the backing material 16 such as crushed stone, body chestnut stone, and on-site generated material is piled up to the height of the container 2 on the anchor 3 and the washer 9 which are the uppermost stage. And a mounting surface is formed. Thereby, the stable mounting surface of the construction material 1 for the next civil engineering structure 1 to be stacked is ensured, the stacking work of the construction material 1 for the civil engineering structure 1 is facilitated, and the shaft portion 7 and the backing material 16 are achieved. , The resistance to movement to the river side based on the engagement of the plate surface of the washer 9 with the backing material 16 in an engaged state with each other is obtained, the holding state of the anchor 3 is enhanced, and the container 2 slides down ( Movement) is prevented.
  In particular, in the above construction, from the viewpoint of further preventing the container 2 from sliding off, when the backing material 16 is piled on the anchor 3 and the washer 9, pressure is applied from the outside (upper part) by a roller or the like (rolling). It is preferable to increase the density of the backing material 16 by pressure) and increase the frictional force (including the movement resistance of the washer 9) between the backing material 16, the anchor 3 and the washer 9. In FIGS. 1 and 3, reference numeral 17 denotes a suction prevention sheet for preventing the suction of earth and sand.
[0024]
  As a result of such construction, as shown in FIG. 1, a revetment 15 is formed in which the container 2 of each construction material 1 for a civil engineering structure constitutes a revetment wall surface (protection wall). While being strong, it is possible to grow aquatic organisms and the like, and it is possible to proliferate the plants 27 for each container 2.
[0025]
  By the way, as shown in FIG. 3, it may be necessary to bend so that the storage container 2 may be piled up and a protective wall (surface of a civil engineering structure) may bulge out. In this case, similarly to the case where the protective walls are connected in a flat manner, the presence of the arc-shaped side wall portion 2c can narrow the gap 18 space formed between the adjacent storage containers 2, and the frontage is wide and the depth is forward. A gap 18 (shown by a slanted line in FIG. 6) that has been pushed out is formed, and the surface of the protective wall can be brought close to a flat surface even in the portion where the gap 18 is formed. Moreover, the gap 18 having a wide opening and a depth pushed forward is not limited to the case where the protective wall is curved so as to bulge outward, as shown in FIG. It will be formed regularly between. For this reason, by using the construction material 1 for a civil engineering structure, regardless of whether or not the protective wall (surface of the civil engineering structure) has to be curved so as to bulge outward, the gap 18 between the adjacent storage containers 2 Can be regarded as a pattern close to a flat surface, and only when the protective wall is curved so as to bulge outward, the uncomfortable feeling that the deep gap 18 is formed can be removed.
  Further, the gap 18 formed between the adjacent storage containers 2 (a gap where the frontage is wide and the depth is pushed forward) is appropriate as a soil accumulation, a stagnation space, etc. It can also enhance the natural environment.
[0026]
  FIG. 7 shows the second embodiment, FIG. 8 shows the third embodiment, FIG. 9 shows the fourth embodiment, FIGS. 10 and 11 show the fifth embodiment, and FIGS. 12 and 13 show the sixth embodiment. In each of the embodiments, the same components as those of the first embodiment and the embodiment described before the embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0027]
  The second embodiment shown in FIG. 7 shows a modification of the anchor 3 according to the first embodiment. In the anchor 3 according to this embodiment, a plurality of grooves 20 and marks 21 are formed on the upper and lower portions of the outer periphery of one end of the shaft-like portion 7. Each groove has a width of about 5 mm, and each groove 20 is located at a position where the end groove 20 is about 10 mm from one end of the anchor 3, and subsequently, the other grooves 20 are spaced about 5 mm apart. Opened and sequentially positioned toward the other end of the anchor 3. As shown in FIG. 7, the mark 21 forms a V-shaped groove, and the position is an inner position of about 15 mm from the innermost groove, and an inner position of about 50 mm from one end of the anchor 3. It is the position on the side.
  When the anchor 3 is used, one end of the anchor 3 together with an adhesive is inserted into a hole formed in advance in a wall material such as a natural stone, a concrete block, a concrete container or the like up to a mark position. Increases the adhesion area or the engagement area, and the mark determines a predetermined insertion amount.
[0028]
  The third embodiment shown in FIG. 8 also shows a modification of the anchor 3 according to the first embodiment. In the anchor 3 according to this embodiment, the curled portion 8 is formed so as to swell only on one side with respect to the axis of the shaft-like portion 7.
  As a result, the curled portion 8 can be easily processed as compared with the case where the curled portion 8 is formed so as to swell on both sides with respect to the axis of the shaft-like portion 7. In this case, when an external force acts on the washer 9 toward the curled portion 8, the curled portion 8 is reduced in diameter as the washer 9 moves, which increases the repulsive force, Based on this, the curled portion 8 regulates the movement of the washer 9.
  In this embodiment, the bending portion 8 is bent so as to expand only on the bending end side, but conversely, it may be bent so as to expand only on the bending start side. In that case, the winding part 11 and the bending start part 12 can be engaged similarly to the said 1st Embodiment, and the effect similar to the same embodiment can be acquired.
[0029]
  In the fourth embodiment shown in FIG. 9, the washer 9 is omitted from the anchor 3 and the curled portion 8 is directly used as a frictional force increasing means. In this case, the crushed stone, the chestnut chestnut and the like in the engaged state and the curled portion 8 are engaged, and even if the washer 9 is not provided, a large movement is performed based on the same action as in the first embodiment. Resistance can be obtained.
[0030]
  In the fifth embodiment shown in FIGS. 10 and 11, the wall surface material 2 for civil engineering structure does not have a rear wall portion, and the front wall portion 2a and the side wall portion 2c are integrally formed in an arc shape, Side wall part 2c is formed in circular arc shape so that a rear end may spread in the width direction of construction material 1 for civil engineering structures rather than a front end.
  Accordingly, the accommodation space 4 that can secure the vegetation soil 26 and the like can be formed with a simple configuration, and at the time of construction of the civil engineering structure, the vegetation soil 26 and the like can be filled from the rear side to improve workability. In addition to being able to bend, as shown in FIG. 11, by using the construction material 1 for a civil engineering structure in a portion (place) where the surface of the civil engineering structure (the revetment 15 or the like) must be curved so as to bulge outward. The larger the degree is (see θ1, θ2 in FIG. 11), the abutting portions of the adjacent wall surfaces 2 for civil engineering structures are pushed forward, and the surface of the civil engineering structure formed by the wall materials 2 for both civil engineering structures. Can be brought closer to a smoother surface.
[0031]
  The sixth embodiment shown in FIGS. 12 and 13 shows a modification of the fifth embodiment. In the sixth embodiment, the bottom wall portion 2d below the accommodation space 4 protrudes toward the other end side of the anchor 3 from the side wall portion 2c. The wall 2 a is connected via a rib 22. As a result, not only the same effects as those of the fifth embodiment can be obtained, but also the strength against external force from the front of the front wall 2a and the like can be increased, and further, the mounting of the bottom wall 2d Based on the increase in area (weight) such as vegetation soil accumulated on the bottom wall 2d, the movement resistance of the wall material 2 for the civil engineering structure itself is increased, and the stability of the wall material 2 for the civil engineering structure is improved. Will be able to.
