Description

The present disclosure relates to a road surface bump elimination unit and a road surface unevenness elimination method.

BACKGROUND ART Conventionally, there has been known a road surface unevenness eliminating material for eliminating unevenness occurring on a road surface. This conventional road surface unevenness eliminating material includes a base block made of foamed resin, a load distribution member, and a suitable number of reinforcing members (Patent Document 1, Abstract, Claim 1, etc.). The base block has a bottom surface and an inclined top surface which is inclined at a predetermined angle with respect to the bottom surface. A load spreader is provided on the slanted upper surface of the foundation block. The reinforcing member is provided along the inclination direction of the inclined upper surface portion of the foundation block. Further, the load distribution member is provided on the foundation block with the reinforcing member installed on the inclined upper surface of the foundation block.

In some cases, the conventional road surface level difference elimination material is divided into two or more divided road surface level difference elimination materials in the inclination direction of the inclined upper surface (Patent Document 1, Abstract, Claim 2, etc.). In this case, each divided road surface level difference elimination member is joined by a connection mechanism.

In addition, a temporary slope suitable for pushing a trolley through a stepped portion provided in a work area such as a construction site or a manufacturing site has been known. This conventional temporary slope is a slope that is temporarily installed in a stepped portion between a low-floor portion and a high-floor portion, and has a plurality of rectangular blocks and inclined blocks (Patent Document 2, Claim 2). etc). The rectangular block is made of a resin material and has a length longer than its height. The slanted block is obtained by cutting a rectangular block along a diagonal line in the length direction.

In the conventional temporary slope, the rectangular blocks are stacked on the stepped portion in a stepped manner, and the inclined block is arranged on the upper part of the arranged rectangular blocks and next to the step composed of one step of rectangular blocks, The inclined surface formed by the inclined blocks is configured to be continuous. This temporary slope has a connecting mechanism between adjacent blocks or stacked blocks.

The above-mentioned conventional road surface unevenness eliminating material can quickly and easily eliminate unevenness on the road surface. and the higher portion can be connected by a continuous slope. However, if the level difference is further increased, the height of the divided road surface level difference elimination member increases, resulting in an increase in weight, which may make installation by workers difficult.

Therefore, it is conceivable to use the rectangular block of the conventional temporary slope together with the road surface unevenness eliminating material. However, the upper surface and the bottom surface of this rectangular block are respectively formed with a convex portion and a concave portion that constitute the connecting portion (Patent Document 2, FIGS. 4 and 5, etc.). For this reason, when installing rectangular blocks, for example, workers may lose their balance by tripping on the protrusions on the upper surface of the rectangular blocks, or the recesses of the rectangular blocks may become clogged with dust and interfere with the connection of the upper and lower rectangular blocks. As a result, the safety and efficiency of the installation work may decrease.

The present disclosure provides a road surface unevenness elimination unit and a road surface unevenness elimination method capable of eliminating unevenness higher than before and improving the safety and efficiency of installation work by workers.

Raising materials 12 are vertically stacked in three stages. The number of raising materials 12 arranged side by side in the step passing direction Ds may be two, three, or five or more, and the number of stages of raising materials 12 stacked vertically may be four or more. .

In the example shown in FIG. 1, the plurality of raising members 12 of the road surface level difference elimination unit 1 include a first raising member 12A and a second raising member 12B. In the step passing direction Ds, the dimension of the second raising material 12B is larger than the dimension of the first raising material 12A. In the step passing direction Ds, the dimension of the first raising material 12A is, for example, about 500 mm, and the dimension of the second raising material 12B is, for example, about 880 mm. The dimension of the second raising material 12B in the step passing direction Ds is, for example, about one third of the dimension of each road surface level difference elimination member 11 .

The operation of the road surface unevenness eliminating unit 1 of this embodiment will be described below.

For example, when a natural disaster such as an earthquake occurs, a step S may occur at a road joint such as an expressway or a road bridge. Moreover, when a disaster occurs, a gap G may occur in addition to the step S at the road joint. In such a case, it is required to quickly eliminate the step S and the gap G on the road surface R to allow emergency vehicles rushing to the disaster site and vehicles such as trucks transporting supplies to the disaster site to pass. be.

The conventional road surface level difference elimination material described in the above-mentioned Patent Document 1 can quickly and easily eliminate the level difference that occurs on the road surface. Even with a higher step of about 30 cm, it is possible to connect the lower portion and the higher portion with a continuous slope. However, if the level difference is further increased, the height of the divided road surface level difference elimination member increases, resulting in an increase in weight, which may make installation by workers difficult.

Therefore, it is conceivable to use the rectangular block described in the above-mentioned Patent Document 2 together with the road surface unevenness elimination material. However, the upper surface and the bottom surface of the rectangular block are respectively formed with a convex portion and a concave portion that constitute the connecting portion. For this reason, when installing rectangular blocks, for example, workers may lose their balance by tripping on the protrusions on the upper surface of the rectangular blocks, or the recesses of the rectangular blocks may become clogged with dust and interfere with the connection of the upper and lower rectangular blocks. As a result, the efficiency of the installation work may decrease.

On the other hand, the road surface level difference elimination unit 1 of this embodiment eliminates the level difference S generated on the road surface R by the following configuration. The road surface level difference elimination unit 1 includes two or more road surface level difference elimination members 11 whose upper surface 11a is inclined at a predetermined angle θ with respect to the bottom surface 11b, and a plurality of flat raising members 12 . Each road surface level difference elimination member 11 is divided into two or more road surface level difference elimination members 111, 112, 113 in the inclination direction Dt of the upper surface 11a. Of these two or more divided road surface level difference elimination members 111, 112, 113, the first road surface level difference elimination material 11A is arranged to move from the level difference S so that the inclination direction Dt is aligned with the level difference passing direction Ds in which the vehicle passes the level difference S. It is installed on the road surface R at the farthest position. Two or more raising members 12 among the plurality of raising members 12 are arranged side by side on the road surface R adjacent to the first divided road surface level difference elimination member 111 in the step passing direction Ds. Among the two or more road surface unevenness-eliminating members 11, the second road surface unevenness-eliminating member 11B is formed of two or more adjacent road surface unevenness-eliminating members 11A with the inclination direction Dt aligned with the step passing direction Ds. It is installed on the raising material 12 .

Further, the road surface level difference elimination method of the present embodiment includes two or more road surface level difference elimination materials 11 in which the upper surface 11a is inclined at a predetermined angle θ with respect to the bottom surface 11b, a plurality of flat plate-like raising materials 12, and each road surface unevenness eliminating material 11 is divided into two or more divided road surface unevenness eliminating members 111, 112, 113 in the inclination direction Dt of the upper surface 11a, using the road surface unevenness eliminating unit 1 Eliminate gaps. Specifically, first, among the two or more road surface unevenness eliminating members 11, the first road surface unevenness eliminating member 11A is aligned with the unevenness passing direction Ds in which the vehicle passes over the unevenness S so that the inclination direction Dt of the road surface unevenness eliminating member 11A is aligned with the unevenness S. is installed on the road surface R at the position farthest from the Next, two or more raising members 12 among the plurality of raising members 12 are arranged side by side on the road surface R adjacent to the first road surface level difference elimination member 11A in the step passing direction Ds. Among the two or more road surface unevenness eliminating members 11, two or more road surface unevenness eliminating members 11 are arranged adjacent to the first road surface unevenness eliminating member 11A with the inclination direction Dt aligned with the unevenness passing direction Ds. is installed on the raising material 12.

With such a configuration, the road surface unevenness eliminating unit 1 and the road surface unevenness eliminating method of the present embodiment include the first road surface unevenness eliminating material 11A installed on the road surface R and the first road surface unevenness eliminating material 11A. A level difference S generated on the road surface R is eliminated by two or more raising materials 12 installed on the road surface R by means of a second road surface level difference eliminating material 11B installed on the two or more raising materials 12. can do. As a result, the height of the second road surface unevenness eliminating member 11B can be raised by the raising material 12, and for example, the level difference S, which is about 40 cm to about 60 cm higher than the conventional one, can be raised by the individual road surface unevenness eliminating member 11. It becomes possible to eliminate without increasing the height.

Therefore, among the two or more divided road surface level difference eliminating members 111, 112, 113 constituting the road surface level difference eliminating member 11, it is arranged closest to the level difference S, and the rear end portion on the side of the level difference S has the maximum height.

Therefore, according to the road surface unevenness elimination unit 1 of the present embodiment, it is possible to improve the safety and efficiency of the installation work performed by the worker as compared with the conventional one.

In addition, when the conventional rectangular blocks described in Patent Document 2 are stacked on a road surface, for example, a step occurs between the adjacent rectangular blocks due to unevenness of the road surface.
