Only retaining walls with a normal gradient can be constructed. That is, it is necessary to use another block in which the formation position of the uneven portion is different each time the normal gradient of the retaining wall is different. Therefore,
There is a problem in that the cost must be increased because a plurality of irregular blocks must be manufactured.

The connection method of each block 1 can be constructed by repeating the work reverse to the above. 16 and 17, the case of constructing a retaining wall having a relatively steep normal gradient θ2 and having a radius R2 in plan view has been described, but the present invention is not limited to this. Further, since the side surfaces of each of the semi-circular convex portions 13 and the circular arc convex portions 15 are respectively formed as circular arc surfaces, the upper block 1 does not change even if the working surface curves and the angle between the lower blocks changes. The convex portion 13,
Since it is configured to abut on the lower block with the radius R of 15, it can be easily dealt with. The semi-circular convex portion 14 is for making the rectangular cylindrical block 1 stand by itself during transportation.

の発生等もないといった諸効果がある。As described above, the green retaining wall building block according to the present invention has a plan view in which the left and right front side walls and rear side walls, the front wall and the rear wall having the same width, are vertically opened.
When forming a square prismatic block, wing portions are respectively provided at the intersections of the front side wall and the rear side wall, and arcuate concave portions that open to the outer surface are formed on the upper surface of the wing portions. Each of the lower surfaces is formed with a circular arc-shaped convex portion that can come into contact with the rear surface wall, and a semi-circular convex portion that can be fitted with the circular arc-shaped concave portion of the upper surface of the blade is formed in the center of the lower surface of the front wall. With this structure, it is possible to construct a retaining wall with an arbitrary gradient by simply changing the laminated state with the same block, and it is possible to reduce the cost, and also to the curved retaining wall. It can be dealt with easily. Further, since the rear half of the bottom surface of the rectangular tubular block composed of the left and right rear side walls and the rear wall is closed by the ascending slope wall that gradually rises toward the rear wall, the rear surface of the block when the retaining wall is constructed is constructed. Even if the amount of excavated soil is small, there are various effects such as well drainage in the vegetation space and no root rot.
