Description of the Related Art Conventionally, a retaining wall block has a vertical gap between a front wall constituting the front surface of the retaining wall and a rear wall on the ground side, and the blocks are stacked, and the gap is filled with concrete. Then, the retaining wall was constructed by integrally forming the blocks.

としていた。In order to prevent this inconvenience, a half groove is provided on the side wall of the block, and when the blocks are stacked, a drain hole is formed in cooperation with the hole of the adjacent block. A proposal has also been made (JP-A-5-339954).
issue). However, in this proposal, it is necessary to accurately adjust the hole groove position of the adjacent block, and furthermore, the bottom of the block forms an angle with the horizontal, and one water hole is formed to secure the inclination of the drain hole. A hole groove for forming a hole extends over the upper and lower blocks. Therefore, at the boundary between the upper and lower blocks, there is a possibility that leakage may occur from the drain hole and backflow to the ground may occur, and eventually, it is necessary to insert pipes along the groove. In addition, many scaffolds were used, and the work was performed in an unstable state, which required complicated work.

The outer wall 2 faces the outer surface 2 of the front wall 1 and the outer surface 8 of the rear wall 7 (FIGS. 1, 2, and 7). The drain hole 25 is 2.0% relative to the horizontal so as to be inclined downward toward the front wall 1 side.
A gradient of about 2.5% is formed.

One is provided on each side of the connecting wall, but if the height is higher than the width, two may be provided above and below (not shown). Further, it is desirable that the reinforcing ridge is formed at a substantially intermediate height and in a substantially horizontal direction. However, if the reinforcing ridge is connected to the front wall, the connecting wall, and the rear wall, the reinforcing ridge may be inclined from the horizontal, for example, the front wall. Can also be provided at right angles to the inner surface of the.

The outer surfaces of the front wall are arranged so as to be flush with each other, and the vertically adjacent blocks are arranged in a staggered manner. A backing material (such as gravel) 38 is interposed between the ground 37 and the outer surface 8 of the rear wall 7 of the retaining wall block 30 (FIG. 9).

できる。Further, the connecting projection of the lower retaining wall block fits into the gap between the inner surface of the front wall and the inner surface of the rear wall of the retaining wall block located above, so that the concrete block is filled with concrete. The displacement is prevented (FIGS. 9 and 10). Also, the front and rear walls 1, 7
Since the center of gravity of the retaining wall block 30 is located at the upper rear due to the inclination and the concave portion 20, the backing material is compacted, the stability up to concrete filling is extremely good, and the empty pile can be stacked higher than usual.

作業を簡略化する。Also, since the upper and lower retaining wall block overlapping surfaces are substantially horizontal, the front wall and the rear wall are constructed to be inclined by stacking the retaining wall blocks up and down. Lamination work is easy. Furthermore, since the complicated work of burying the pipe for the drain hole that was required in the past is eliminated,
Accurate positioning of the adjacent retaining wall blocks and the like are not required, and temporary construction of the work scaffold can be omitted, and the work of stacking the retaining wall blocks can be simplified.

Therefore, the retaining wall block 30 and the retaining wall block 31 are used in an appropriate combination. In addition, a half retaining wall block 32 having a similar structure in which the width of the front wall and the rear wall is formed in half,
33 (FIGS. 8, 10). The retaining wall block 3
2 is a type having a drain hole 25, and a retaining wall block 33 is a type without the drain hole 25.

By making the connecting projection 17 smaller than the one shown,
The upper and lower retaining wall blocks 30 are provided with the concave portions 20 and the connecting protrusions 17.
Are substantially fitted to each other so that they can be easily stacked vertically (not shown).

Therefore, the foundation concrete 36 and the retaining wall block 30 and the like can be firmly connected, and the stability of the stacked retaining wall blocks is enhanced. When the foundation wall 36 is not provided and the retaining wall block is directly placed on the ground leveled with gravel or the like (not shown), the gap 3
The concrete in 9 is driven together with the gravel and the like to increase the stability of the similarly stacked retaining wall blocks.

Since 3 is provided in a substantially horizontal direction, it serves as a guide for jointing, so that work efficiency can be improved. Further, usually, the seam of concrete is not horizontal, and a step is provided at the seam by interposing a square bar or the like. In this case, the reinforcing ridge also supports the square bar (for raising or moving the square bar). To prevent)

Since it is moved to the side, there is no risk of falling to the front side when the layers are stacked up and down, and there is an effect of stabilizing even an empty stack. Therefore, since a larger number of blocks can be stacked at one time than before, there is an effect that construction efficiency can be improved.

There is an effect that can be done. Also, when forming a step on the joint surface of concrete, even if the specific gravity of the square bar used is reduced, it is possible to prevent the rising and movement of the square bar, and it is also possible to lighten the square bar, so that it is easy to handle, Overall, it has the effect of increasing construction efficiency.
【００３８】更に、水抜き孔を形成した場合には、従来

を省くので、作業足場の仮設を省略して、作業の安全を
確保すると共に施工を簡略化するので、施工効率を高め
て工期の短縮を図ることができる効果がある。Further, in the case where the drain hole is formed, the time and labor for interposing a pipe or the like between the retaining wall blocks as in the related art is omitted, so that temporary work scaffolding is omitted, and work safety is reduced. Since it secures and simplifies construction, there is an effect that construction efficiency can be increased and the construction period can be shortened.
