Description

[Detailed explanation of the idea] When constructing a retaining wall on a conventional river bank or mountain slope, the common method is to stack small blocks, but the stacking process is difficult and the inner side of the retaining wall is difficult to build. It had the disadvantage that it would collapse if earth or water pressure was applied to it.

The present invention relates to a block retaining wall that is easy to construct by stacking large blocks and can withstand earth and water pressure without collapsing.The structure is shown in the attached drawing. The details for reference are as follows.

Connecting plates 2 are arranged substantially perpendicularly on the left and right sides of the square plate 1, and grooves 3 are formed in the longitudinal direction of the outer surface of the connecting plates 2 to form a large concrete retaining wall block a.

The large retaining wall blocks a are arranged horizontally or stacked vertically as necessary to form a block retaining wall b, and the adjacent large retaining wall blocks a are connected at several points in the vertical direction of the connecting plate 2. are connected in the horizontal direction by bolts 4 and nuts 5, and concrete 7 is poured into concrete vertical holes 6 formed by the two grooves 3 of the connecting plate 2 and hardened.

Furthermore, when pouring the concrete 7 into the concrete vertical hole 6, it is a good idea to also insert the reinforcing bars 8 together.

9 in the figure is a drainage hole.

Since the present invention is constructed as described above, it has the following features.

1. Block retaining wall body B is formed by simply arranging large retaining wall blocks A in the left and right direction, which greatly improves construction efficiency compared to the conventional method of lining up small blocks or piling them up. .

2. The method of connecting this large retaining wall block a is to butt the left and right connecting plates 2 against each other, and then connect the connecting plates 2 in several horizontal positions with respect to the vertical direction using bolts 4 and nuts 5. Retaining wall blocks a will be strongly connected.

3 Moreover, since grooves 3 are formed on the outside of the connecting plate 2, concrete vertical holes 6 are formed by adjacent grooves 3, and concrete 7 is poured into this concrete vertical hole 6 and hardened. Therefore, concrete reinforcing rods are provided at regular intervals in the vertical direction of the block retaining wall b, making the block retaining wall b that much stronger.

4 Furthermore, since the concave portion between the left and right connecting plates 2 can be filled with split stones 10, a block retaining wall body b that is even stronger and can withstand water pressure and earth pressure is formed.
