Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roadside belt block suitable for preventing a road shoulder from collapsing by being laid on a roadside belt of a road constructed by raising earth and sand higher than the surroundings.
[0002]
[Prior art]
In order to prevent the shoulders of roads higher than the surroundings from collapsing due to rain, and in order to improve the scenery of the shoulders, a roadside belt block has been conventionally laid and protected. The conventional roadside belt block has a substantially “H” -shaped cross section in which a plate-like portion laid on the road surface side and a plate-like portion laid on the slope side are integrally molded. The degree of bending angle between the road surface side portion and the slope side portion is set according to this angle since the slope angle of the slope is known in advance at the road design stage. In fact, since the slope angle of the slope is standardized, the bending angle of the roadside block is also manufactured according to this standard, and the one that matches the slope angle of the designed road slope is selected. Lay.
[0003]
[Problems to be solved by the invention]
However, in actual road construction work, it is not easy to construct exactly the slope angle of the slope that has been leveled by raising the earth and sand as designed over the entire length, and some “undulation” remains. In addition, it is not always sufficient to roll the slope because it is not as easy as a horizontal road surface. For this reason, even if a conventional roadside belt block having a substantially “H” cross section is selected according to the design angle of the slope, a small gap is actually generated on the lower surface of the block due to slope construction errors or undulations. . In particular, a gap is likely to occur in the slope portion. And when a clearance gap arises in the lower surface of a block, earth and sand near a clearance gap will move easily over the years, and when a clearance gap grows, a slope will collapse and protection will become insufficient.
[0004]
In addition, as time passes, a phenomenon occurs in which the vicinity of the sloped lower end of the block covering the road shoulder is greatly swollen. This is because, when it rains, when rain water on the road surface flows from the shoulder of the road to the lower part of the surrounding area, the earth and sand in the vicinity of the inclined lower end of the block flows out. In other words, the part covered by the block is hard to be shaved by rainwater, but the part where the slope of the block is interrupted is still exposed, so the earth and sand of this part is gradually broken down by the rainwater flow and flows out. Then, by repeating this, the lower part of the inclined lower edge of the block is scooped out. If this gap part grows with the passage of time, the slope will collapse and the protection will be insufficient.
[0005]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a roadside belt block that can protect the slope of the roadside belt for a long period of time.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a first embodiment of a roadside belt block 1, and FIG. 2 is a side view of the roadside belt block 1 shown in FIG.
[0010]
The roadside belt block 1 shown in FIG. 1 includes a plate-shaped concrete first block portion 2 laid on the road surface side, a plate-shaped concrete second block portion 3 laid on the slope side, and a first block portion 2. The first block portion 2 and the second block portion 3 that are connected by the connecting member 4 are configured to connect the blocks 2 and 3 with one side of the second block portion 3 facing each other. The angle can be adjusted according to the inclination of the construction site.
[0011]
The first block portion 2 is a concrete thick plate, and a water gradient is formed on the upper surface with a slight downward slope (for example, 2%) from the road surface side to the slope surface side. On the other hand, a notch 8 is formed through which a guard rail post or the like penetrates, and a concave groove 5 having a substantially U-shaped cross section is formed on the end surface facing the second block portion 3 along the longitudinal direction of the end surface. In the same manner, a groove 6 having a substantially U-shaped cross section is formed along the longitudinal direction of the end surface on the end surface on the road surface side opposite to the end surface. In this end face, a female screw hole 7 for screwing a suspension bolt, for example, an eye bolt (not shown) is formed by embedding a nut or the like. In addition, the magnitude | size of this 1st block part 2 can be set suitably. For example, the length in the direction along the road may be 100 cm, the width is 75 cm, and the thickness is 10 cm.
[0012]
The second block portion 3 is a concrete thick plate similar to the first block portion 2, and a concave groove 10 having a substantially U-shaped cross section is formed on the end surface facing the first block portion 2 in the longitudinal direction of the end surface. Along with the connecting member 4, two upper and lower parts are formed in parallel, and a female screw hole 11 into which a suspension bolt, for example, an eyebolt is screwed is formed on the end face opposite to the end face. In addition, the magnitude | size of this 2nd block part 3 can be set suitably. For example, the length in the direction along the road may be 100 cm, the width is 100 cm, and the thickness is 10 cm.
[0013]
The connecting member 4 may have any configuration as long as it has a function of connecting the first block portion 2 and the second block portion 3 so that the angle can be adjusted.
The embodiment of the connecting member 4 shown in FIG. 1 to FIG. 3 is a hinge mechanism (hinge) capable of restricting the rotation range, and specifically, a substantially C-shaped cross section fixed to the end face of the first block portion 2. The hollow pipe 12 and a rotation shaft member 13 fixed to the end face of the second block portion 3 are roughly configured. The hollow pipe 12 is configured such that a cutout portion 15 is formed in the circumferential direction on the outer peripheral surface below the laterally long opening portion 14 in the longitudinal direction, and an arm portion 16 described later enters the cutout portion 15. The hollow pipe 12 is fixed in a state of projecting a predetermined length from the end face of the first block portion 2 by burying the tip end portion of the support arm 17 projecting in the radial direction in the first block portion 2. ing.
[0014]
On the other hand, the rotation shaft member 13 includes a shaft member 18 having a thickness that fits inside the hollow pipe 12 and an arm portion 16 fixed in a direction orthogonal to the shaft member 18. Is embedded in the second block portion 3 to be fixed in a state protruding from the end face of the second block portion 3 by a predetermined length. The arm portion 16 has a thickness that fits into the cutout portion 15 of the hollow pipe 12, and has a stopper 19 for retaining it at the tip, similarly to the support arm 17.
[0015]
In order to connect the first block portion 2 and the second block portion 3 by the connecting member 4 having such a configuration, both the blocks 2 and 3 are placed on the same plane, and in this state, the second block portion 3 One end of the shaft member 18 of the protruding rotating shaft member 13 is inserted and connected from the end opening of the hollow pipe 12 protruding from the first block portion. When both the blocks 2 and 3 are positioned on the same plane, the end opening of the hollow pipe 12 and the shaft member 18 of the rotation shaft member 13 are not only positioned at the same height, but also the rotation shaft member 13 Since the arm portion 16 is located at the same height as the horizontally long opening 14 of the hollow pipe 12, the shaft member 18 of the rotating shaft member 13 is inserted into the hollow pipe 12 by moving both the blocks 2 and 3 in the lateral direction. can do.
[0016]
When it is fully inserted to a predetermined position, that is, until it is inserted until the left and right side edges of the second block part 3 are aligned with the left and right side edges of the first block part 2, the arm part 16 of the rotary shaft member 13 is hollow. It is located on the notch 15 of the pipe 12. For this reason, when the second block portion 3 is to be rotated upward with the first block portion 2 being positioned horizontally, the arm portion 16 of the rotation shaft member 13 is positioned above the opening of the horizontally long opening portion 14 of the hollow pipe 12. Since it abuts against the edge, it cannot be rotated further, but when the second block portion 3 is rotated downward, the arm portion 16 of the rotation shaft member 13 enters the notch portion 15 of the hollow pipe 12. Since it enters, the 2nd block part 3 can be rotated below and can be bent in a "heavy" shape.
[0017]
Therefore, the connecting member 4 according to the present embodiment has a connecting angle in a range from the state in which the first block portion 2 and the second block portion 3 are largely opened and substantially straight to the blocks 2 and 3 being substantially perpendicular. Can be adjusted. The connecting angle between the blocks 2 and 3 can be set by the length of the notch 15.
[0018]
In order to manufacture the roadside belt block 1 having such a configuration, the first block portion 2 and the second block portion 3 are separately molded in a factory, and then connected by the connecting member 4. And when conveying to a construction site, the 1st block part 2 and the 2nd block part 3 are opened largely, and it is set as the state where both blocks 2 and 3 are located on the same plane, and it is an eyebolt in the internal thread hole 7 in this state. And the blocks 2 and 3 can be stacked on the truck in this state without being bent into a V shape. Therefore, it can be conveyed to the construction site in this flat state. When transported in this manner, it does not become bulky compared to the conventional “H” shaped block, and is wide open and stable, so that it can be transported safely and easily.
[0019]
In order to lay at the construction site, the foundation layer 21 is prepared in advance, the slope is grounded at a predetermined inclination angle and rolled, and in this state, the roadside belt block 1 is lifted by a crane and lowered to a predetermined position. At this time, the first block portion 2 is lowered onto the horizontal base layer 21 and the second block portion 3 is lowered onto the slope. And even if some errors and undulations remain even if the angle between the underlayer 21 and the slope is the designed angle, the opening angle of both blocks 2 and 3 is determined by the connecting member 4 in the field. Since the angle is freely changed according to the angle, that is, adjusted, no gap is generated on the lower surface of the first block portion 2 or the second block portion 3. In other words, the angle between the upper surface of the base layer 21 on the road surface side on which the first block portion 2 is placed and the slope on which the second block portion 3 is placed is the rotation range of the connecting member 4 (the angle at which the connection member 4 can rotate). ), The first block portion 2 and the second block portion 3 can be opened following the mounted angle. Therefore, the roadside belt block 1 can be installed in an extremely stable state.
[0020]
If the roadside belt blocks 1 are sequentially arranged in this way, the road shoulders of the road can be covered and protected in series by the roadside belt block 1. And about the roadside belt block 1 lowered | hung to the predetermined position, the anchor pin 23 is driven into the through-hole 20 of the 1st block part 2 and the 2nd block part, respectively, and it fixes to a predetermined position. Moreover, sediment is piled up below the inclined surface of the second block portion 3 to form a series of inclined surfaces, and ready-mixed concrete is used as a filling material 24 in the gap between the first block portion 2 and the second block portion 3. The filling material 24 is used to form a series of surfaces from the upper surface of the first block portion 2 to the inclined surface of the second block portion 3. Accordingly, when it rains, rainwater that has fallen on the asphalt road surface flows down on the second block portion 3 from the first block portion 2 through the padding material 24 and then flows down on the second block portion 3. It penetrates into the sloped sand or flows down along the slope. In this way, since rainwater on the road surface can be drained by flowing it from the first block part 2 to the second block part 3, it is possible to prevent the roadside earth and sand from collapsing, and to improve the roadside landscape. There is. And since there is no gap under the second block part as well as under the first block part, there is no movement of earth and sand even after a long period of time, and it is possible to eliminate the inconvenience caused by the conventional gap. it can.
[0021]
In addition, when the ready-mixed concrete is filled in the gap between the first block part 2 and the second block part 3, a part of the groove 5 or the second block part 3 formed on the end face of the first block part 2 is used. Since it enters into the recessed groove 10 formed on the end face, after hardening, the inserted part is caught to prevent the filling material 24 from coming off, and a gap is formed between the end surfaces of the blocks 2 and 3 and the filling material 24. Weeds can be prevented from growing through. Moreover, in this embodiment, since the ditch | groove 6 is formed also in the road side end surface of the 1st block part 2, when asphalt pavement, since a part of asphalt compound material enters in the said ditch | groove 6, asphalt Weeds can be prevented from extending through a slight gap between the pavement and the first block part 2, and the load is paved when an automobile tire or the like is placed on the first block part 2 and a load is applied. Since it can disperse | distribute to the side, it can prevent that the 1st block part 2 rattles, and it becomes difficult to produce a clearance gap between the 1st block part 2 and pavement.
[0022]
In addition, the first block portion 2 described above is a simple plate-like body having a water gradient formed on the upper surface, but as shown by a dotted line in FIG. 2, the second block portion 3 side, that is, the side on which the connecting member 4 is provided. You may integrally form the protrusion 25 which becomes a curb block on the one side upper surface. And when installing a guardrail, the support | pillar 26 can be installed upright by making the notch part 8 formed in the 1st block part 2 penetrate.
[0023]
By the way, the rainwater that has flowed down on the second block portion 3 directly hits the slope of the slope immediately after passing through the inclined lower end of the second block portion 3, so that the sand in this portion may be eroded and removed. . Accordingly, the water permeable member 30 is provided on the side edge portion (that is, the side edge portion located on the side opposite to the connecting member 4) located at the lower end of the second block portion 3 in an inclined state, and the second block portion 3 is laid. The rainwater flowing down can be penetrated into the ground in a state of being dispersed through the water permeable member 30, thereby preventing a dip in the vicinity of the inclined lower end of the second block portion 3.
[0024]
For example, the roadside body block 1 shown in FIG. 4 is obtained by joining the insulator fiber block 30a to the inclined lower end side edge of the second block portion 3 by a joining means such as an adhesive. When the water permeable member 30 such as the insulator fiber block 30a is joined to the side edge of the second block portion 3, the rainwater flowing down the inclined upper surface of the second block portion 3 passes through the concrete portion of the second block portion 3. Most of them penetrate into the insulator fiber block 30a. When rainwater permeates into the insulator fiber block 30a, the rainwater hits the fiber to disperse by changing the flow direction and the flow velocity is weakened. As a result, as shown by the arrows in FIG. It penetrates slowly over a wide area. Therefore, it is possible to prevent the earth and sand immediately below the inclined lower end of the second block part 3 from being swept away by the flow of rainwater.
[0025]
Although the water permeable member 30 may be joined to the molded second block part 3 later as in the above embodiment, it may be provided when the second block part 3 is molded. For example, concrete may be placed in a state where the insulator fiber block 30a is set at the end in the mold for molding the second block portion 3. If it does in this way, since a part of concrete cement milk will enter into the insulator fiber block 30a for a while and harden | cure, the 2nd block part 3 can be shape | molded in the state which included the insulator fiber block 30a. In addition, when it shape | molds in this way, the boundary of the cement milk which soaked in the insulator fiber block 30a will appear on the surface of the 2nd block part 3 as an irregular line.
[0026]
Therefore, as shown in FIG. 5, the insulator fiber block 30a is set on one side of the mold 31, and the perforated tape 32 is attached to the side surface (side surface into which concrete is poured) of the insulator fiber block 30a. The concrete milk passes through the holes 33 of the tape 32 and enters only a part of the insulator fiber block 30a to be hardened. Therefore, after molding, the cement milk that has soaked and hardened into a part of the insulator fiber block 30a integrally holds the insulator fiber block 30a as a part of the second block part 3, and the second block part 3 after the molding On the surface, the boundary between the insulator fiber block 30a and the concrete portion becomes a straight line and appears clearly separated. Therefore, an irregular boundary line is not seen and the appearance is good.
[0027]
Further, as shown in FIG. 6, a tape 34 is applied to the lower half of the insulator fiber block 30a so that cement milk enters the insulator fiber block 30a and hardens from the upper half where the tape 34 is not attached. Good. Then, if the lower side where the tape 34 is pasted is reversed and turned into a table, the cement milk does not enter the insulator fiber block 30a on the front side, so the above-mentioned irregular boundary line is not visible, and the insulator fiber block The boundary with 30a appears to be a straight line. In addition, what is necessary is just to stick the tape 34 to the upper half of the insulator fiber block 30a, when not reversing after shaping | molding. Moreover, the width | variety which sticks the tape 34 does not necessarily need to be a half, and can be suitably set with the approach condition of cement milk. Note that the tapes 32 and 34 are members that control the penetration of cement milk into the insulator fiber block 30a in any case, and therefore any material can be used as long as the penetration of the cement milk can be controlled.
[0028]
The water permeable member 30 is not limited to the insulator fiber block 30a having the same thickness as that of the second block portion 3, and as shown in FIGS. 1 and 2, the insulator fiber plate 30b thinner than the second block portion 3. May be mounted flush with the upper surface of the second block portion 3. And the attachment to this 2nd block part 3 of this insulator fiber board 30b may embed the side edge of the insulator fiber board 30b in the 2nd block part 3, and may fix it by hardening of the cement milk impregnated in a fiber. . In short, the water permeable member 30 may be made of any material as long as it can permeate rainwater and permeate it into the sloped sand. For example, it may replace with the said insulator fiber block 30a, and may comprise the inclination lower half part of the 2nd block part 3 with water-permeable concrete. Since the permeable concrete has innumerable continuous fine voids between the aggregates, the rainwater flowing down the upper surface of the second block portion 3 passes through the fine voids and is gradually diffused into the earth and sand. be able to.
[0029]
As shown in FIG. 4, the prevention of slipping by the water permeable member 30 is performed by integrating the plate-like first block portion 2 laid on the road surface side and the plate-like second block portion 3 laid on the slope side. The same can be applied to the roadside belt block 1 that has been changed. That is, when the water permeable member 30 is provided at the side edge portion positioned at the lower end of the second block portion 3, rainwater flowing down the second block portion 3 in the installed state penetrates into the ground through the water permeable member 30. Therefore, it is possible to prevent earth and sand below the inclined lower end of the second block part 3 from moving due to rainwater, and to protect the slope for a long period of time.
[0030]
The connecting member 4 in the present invention is not limited to the above-described hinge mechanism, and may have any configuration as long as the first block portion 2 and the second block portion 3 can be connected so as to be adjustable in angle.
For example, as shown in FIG. 7, a wire 41 having a large diameter portion 40 formed at both ends is used as the connecting member 4, and one end of the wire 41 is embedded in the first block portion 2 and the other end is You may embed in the 2 block part 3. FIG.
[0031]
The connecting member 4 shown in FIGS. 8 and 9 includes a long first rod 43 penetrating into the first through hole 42 opened near one side of the first block portion 2 and one side of the second block portion 3. A long second rod 45 penetrating into the second through hole 44 opened in the vicinity, a first hole 46 penetrating the tip portion of the first rod 43, and a second hole 47 penetrating the tip of the second rod 45. , And a cap nut 49 and a washer 50 which are screwed into the male threaded portion of the first rod 43. And the recessed part 51 is each formed in the side surface of the 1st, 2nd block parts 2 and 3 which the 1st, 2nd through-holes 42 and 44 open, and the front-end | tip of the 1st rod 43 which protruded from the 1st through-hole 42 The male screw portion is inserted into the first hole 46 of the connecting piece 48, the cap nut 49 is screwed through the washer 50, and the distal male screw portion of the second rod 45 protruding from the second through hole 44 is connected to the connecting piece 48. The cap nut 49 is inserted into the second hole 47 of the 48 and screwed through the washer 50 so that the portion including the cap nut 49 can be accommodated in the recess 51. When the first block portion 2 and the second block portion 3 are connected by the connecting member 4 having such a configuration, the angles of the blocks 2 and 3 can be freely adjusted, and the roadside belt block 1 is laid sequentially next to each other. At this time, the adjacent connecting members 4, specifically, the cap nuts 49 do not come into contact with each other.
[0032]
In another embodiment of the connecting member 4 shown in FIG. 10, the base end of the connecting piece 53 protruding from the inside of the recess 52 formed on the side surface of the first block part 2 toward the second block part 3 side is fixed and connected. A shaft portion 55 projecting from the side surface of the second block portion 3 is passed through a substantially arc-shaped long hole 54 formed in the piece 53. Even if comprised in this way, since the axial part 55 protruded from the 2nd block part 3 can move the inside of the long hole 54 of the connection piece 53, the 1st block part 2 and the 2nd block part 3 can be made at a free angle. Can be linked. The connecting piece 53 may have a base end fixed to the second block portion 3 side, and a shaft portion (not shown) protruding from the side surface of the first block portion 2 may be inserted into the long hole 54.
[0033]
In addition, as shown in FIG. 4, if the through-opening part 35 is opened in the 1st block part 2, a plant can also be planted in this through-opening part 35, and a landscape can be improved further.
[0034]
【The invention's effect】
As described above, the present invention has the following effects.
According to the first aspect of the present invention, the connecting angle of the plate-like first block portion laid on the road surface side and the plate-like second block portion laid on the slope side can be adjusted by the connecting member. Can be laid at an angle that matches the actual inclination angle. Therefore, a gap is hardly generated on the lower surface of the roadside belt block, and the roadside belt block can be laid in a stable state. And if a clearance gap does not arise, since earth and sand are hard to move and it is hard to collapse, therefore, a slope can be protected over a long period of time.
In addition, since the same roadside band block can be used even if the slope of the slope is different, it is not necessary to manufacture multiple types of angles, and management such as inventory management of the roadside band block can be simplified. The type of mold can be greatly reduced.
And a water permeable member is provided in the side edge part of the 2nd block part located on the opposite side to a connection member, and when a water permeable member casts concrete in a metallic mold and molds the 2nd block part, A state in which a part of the cement milk enters the inside and is cured and joined to the side edge portion of the second block portion, and the rain water flowing down on the second block portion in a laid state is dispersed through the water permeable member. The second block part can be molded and the water permeable member fixed to the second block part at the same time, and the slope located just below the inclined lower end of the second block part The inconvenience that earth and sand are swallowed by rainwater can be greatly reduced. Therefore, the durability of the slope can be improved.
[0036]
According to the invention of claim 2 , the water permeable member is provided on the side edge portion located at the inclined lower end of the second block portion laid on the slope side, and the water permeable member is formed by placing concrete in the mold. Rainwater that flows down on the second block part in a state where a part of the cement milk at the time of molding the second block part is joined to the side edge part of the second block part in a state where the cement milk has entered and hardened. Can be infiltrated into the ground in a state of being dispersed through the water permeable member, so that it is possible to greatly reduce the inconvenience that the slope soil located just below the inclined lower end of the second block part is swallowed by rainwater. . Therefore, even if the first block portion laid on the road surface side and the second block portion laid on the slope surface side are integrally molded, the durability of the slope surface can be improved.
