In this way, a plurality of earth and sand filling spaces 26 are formed, and each of the earth and sand filling spaces 26 is filled with earth and sand 28.

A wall is formed (portion indicated by oblique lines in FIG. 4E), and the inside of the block-shaped wall is further filled with earth and sand 28 to form a double structure.

In particular, since the side panels are arranged in a flat plate or curved plate shape by arranging multiple vertical reinforcing bars and horizontal reinforcing bars while welding them together so that the mesh forms a rectangular grid, the vertical reinforcing bars and horizontal reinforcing bars are subjected to earth pressure. Even when a large tensile force is applied, the mesh is not likely to be deformed or torn, and a cell structure extremely stable in strength can be constructed.

Since a plurality of earth and sand filling spaces are formed by inserting and connecting adjacent side panels to each other, cell structures of various shapes and necessary scales can be easily constructed according to the installation location and the installation purpose.

定性、施工性にもきわめてすぐれている。In particular, by filling earth and sand into a predetermined thickness around the earth and sand filling space, a block-shaped stable wall in which the earth and sand is restrained by the horizontal reinforcing bar of the side panel is formed. (The portion shown by oblique lines in FIG. 4 (e)), since the inside of this block-shaped wall is further filled with earth and sand to form a double structure, the bending rigidity is extremely large.
It is excellent in independence, and in particular, the side panel itself can stand on its own, so that it is possible to save labor of construction, and it is extremely excellent in stability and workability.
