Description of the Related Art Conventionally, there are almost no earth retaining retaining walls in which a steel sheet pile is used as an outer wall material that also serves as a concrete formwork, and concrete is cast between the outer wall material and the slope, and a construction method therefor. A similar known technique is disclosed in JP-A-11-210.
There is an earth retaining wall constructed by the slope reinforcing retaining wall method described in Japanese Patent Application Publication No. 004-004.

擁壁を完成する。In the slope reinforcing retaining wall method, as shown in FIG. 8, one end of an anchor material a is cast on a slope 2 of a ground 1 and the other end is joined to a concrete panel b. To connect the ground 1 and the concrete panel b. Similarly, a plurality of concrete panels b connected to the ground 1 are piled up and constructed, and the concrete panels b in the vertical and horizontal directions,
b are connected to each other by a reinforcing bar c, and the anchor material a and the reinforcing bar c are further integrated. Concrete 6 is cast between the concrete panels b and the slope 2 of the ground 1 and cured until the strength is developed. The above process is repeated several times to complete the earth retaining wall.

法により構築された土留め擁壁は、アンカー材ａを地山
１の法面２に打設する必要があり作業が煩雑である。The earth retaining wall constructed by the above-mentioned slope reinforcing retaining wall construction method requires the anchor material a to be cast on the slope 2 of the ground 1 and the work is complicated.

b is connected to each other by a reinforcing bar c (specifically, a hole penetrating the concrete panel b in the up-down direction and the left-right direction is provided, and the reinforcing bar c is connected to the hole between the panels b and b so as to be connected). Therefore, even if the arrangement position of the concrete panel b is slightly shifted, the position of the hole is shifted and it is difficult to penetrate the reinforcing bar c, and it is difficult to form the concrete panels b. Even if the arrangement position is shifted, since the concrete panel b has a considerable weight, it is difficult to correct the position and the construction work is complicated. Therefore, the work efficiency is low and the cost increases.
