Description

[Detailed explanation of the invention] (A) Industrial application field This invention relates to blocks for earth retaining and side ditch construction when carving down mountain slopes to create roads.

(B) Conventional technology In the past, retaining walls and side ditches for retaining earth had to be cast separately, assembled on-site, and bolted, which was time-consuming and troublesome.

(C) Problems that the invention seeks to solve Except for its shortcomings, this invention is easy to work on site;
In addition, the aim is to develop a robust earth retaining gutter block.

(D) Means to solve the problem Now, let me explain the solution while following the drawings: (a) Create two grooves 4 on the top surface of the bottom plate part 2 of the L-shaped retaining wall 1 to match the width of the gutter to be constructed. , 5 are recessed, and the lower portions of the vertical side walls 7, 8 of the side gutter 6 without a bottom plate are placed so as to fit into these grooves 4, 5 at the work site.

(b) Concrete is then poured onto the top surface of the bottom plate portion 2 of the L-shaped retaining wall 1 and hardened.

(E) Function Since the present invention has the above-described configuration, it can be constructed extremely easily at a construction site by simply combining the L-shaped retaining wall 1 and the gutter 6 without a bottom plate.

(F) Effect of invention Therefore, B. On-site work is easy.

(b) Can be constructed in any combination according to the width and height of the gutter.

C. During construction, the amount of soil excavated from the backside of the mountain can be reduced.

D. After installation, the vertical part 3 of the L-shaped retaining wall 1 is fixed by the gutter 6 without a bottom plate or one end 6 of its upper plate part, so the rear earth pressure of the vertical part 3 of the L-shaped retaining wall 1 is reduced. Therefore, the inner thickness of the vertical portion 3 can be made thinner and the amount of reinforcing bars can be reduced.

E. When a penetrating hole 9 is formed in the bottom plate part 2 of the L-shaped retaining wall 1, the L-shaped retaining wall 1 and the side gutter without a bottom plate become integrated with the poured concrete, and the combination becomes strong, and the soil and sand below stick.

Claims (1)

[Claims for Utility Model Registration] 1 (a) Two parallel grooves 4 and 5 are recessed in the upper surface of the bottom plate portion 2 of the L-shaped retaining wall 1. (b) The groove 4 is provided almost directly below the vertical portion 3 of the L-shaped retaining wall 1, and the distance between the groove 4 and the groove 5 is the same as the distance between the vertical side walls 7 and 8 of the side gutter 6 without a bottom plate. (c) Insert the lower parts of the vertical side walls 7 and 8 of the side gutter 6 without a bottom plate into the grooves 4 and 5 of the bottom plate part 2 of the L-shaped retaining wall 1, respectively. The combination earth retaining gutter block 2 constructed as described above.The combination according to claim 1 of the utility model registration claim, in which one end 6' of the upper plate part of the gutter 6 without a bottom plate is brought into close contact with the vertical part 3 of the L-shaped retaining wall 1. Earth retaining gutter block 3 Grooves 4 and 5 recessed in the bottom plate part 2 of the L-shaped retaining wall 1
A combination earth retaining gutter block according to claim 1 of the utility model registration claim, in which a penetrating hole 9 is formed between the block and the block.
