Description

[Detailed description of the invention] This invention is an assembly-type retaining wall block in which one retaining wall block is divided into a front plate and a rear plate, which are made lightweight, and are combined into one.

Conventional retaining wall blocks have the disadvantage that they are quite heavy and bulky, making them difficult to handle during transportation and construction.

This proposal aims to eliminate the above drawbacks.

This invention will be explained based on the drawings. Oval shaped holes 8 and grooves 9 are provided at both ends of the upper and lower parts of the front plate 1, which has an angular surface 10 on its surface. Similarly to the front plate 1, the rear plate 2 is also provided with elliptical holes 8 and grooves 9.
Oval holes 5 are arranged at both ends of both sides of the front plate 1 and the rear plate 2, respectively. A non-penetrating hole 6 is inserted into the front plate 1 at the center of the opposing inner sides of the front plate 1 and the rear plate 2.
and applied to the rear plate 2. The connecting rod should be H-shaped or U-shaped so that it can easily enter the oval hole 8 at the tip 11.
Make it thinner.

At the bottom, insert a U-shaped connecting rod 4 into the holes 8 located at both ends of the lower parts of the front plate 1 and rear plate 2, and connect the front plate 1 and rear plate 2.
Connect the bottom of the. Insert the protruding parts 12 of the H-shaped connecting rod 3 from the second stage into the holes 8 at both ends of the upper stage, connect the front plate 1 and the rear plate 2, and then insert the protruding parts 12 of the H-shaped connecting rod 3 into the holes 8 at both ends of the lower part of the upper stage.
By inserting one protrusion 12 of the H-shaped connecting rod 3 into the holder, the front and rear and upper and lower parts can be connected at the same time. The top layer of the stack is the front plate 1 using the U-shaped connecting rod 4.
Finish by connecting and rear plate 2. The elliptical hole 8 and the elliptical hole 5 make it possible to perform horizontal stacking and vertical stacking diagonally. A pipe is passed through the impenetrable hole 6 as necessary, and then concrete is poured between the front plate 1 and the rear plate 2 to form a retaining wall.

By making the elliptical hole 8 and the elliptical hole 5 elliptical, it is possible to insert the connecting rod even if a slight error occurs during construction. Groove 9
is a groove deep enough to accommodate the diameters of the three H-shaped connecting rods 4. This groove is intended to ensure that the lower part of the upper tier and the upper part of the lower tier come into close contact when stacking during construction. The H-shaped connecting rod 3 enables connection of the upper and lower front and back at the same time. The thickness of the retaining wall can be increased or decreased by increasing or decreasing the length of the H-shaped connecting rod 3 and the C-shaped connecting rod 4, and the retaining wall construction can be carried out according to the construction site. By pouring concrete in between, the H-shaped connecting rods 3 and the U-shaped connecting rods 4 serve as aggregates that increase the strength of the concrete.
In the lowermost stage and the uppermost stage, one protrusion of the H-shaped connecting rod 3 is unnecessary, so the U-shaped connecting rod 4 is used. The non-penetrating holes 6 are penetrated where necessary to allow pipes to pass therethrough and serve as drainage ports. The cut of the retaining wall allows rainwater and groundwater generated on the surface to pass through the Kuriishi 7.
Remove water from the drain and relieve water pressure against the retaining wall. In order to make it easier to penetrate the hole, it is left in a non-penetrating state.

Both the front plate 1 and the rear plate 2 are plate-shaped,
Therefore, even if they are piled up, they do not take up much space and are easy to transport. Furthermore, since one retaining wall block is disassembled into two parts, front and rear, it is relatively lightweight and easy to handle.

In addition, there are the following embodiments of the prefabricated retaining wall block.

(a) A method of providing a non-penetrating hole 6 at the center of each of the front plate 1 and the rear plate 2 facing each other.
