To provide retaining wall blocks capable of performing execution work therefor when requiring to cultivate plants, enabling execution work of such a mode when requiring that the execution work surface becomes the smooth surface without requiring to cultivate the plants and being usable not only as a leaning type retaining wall but also as a vertical retaining wall, and a retaining wall execution work method using it.
The upper side 1a and the bottom side 1b are set almost parallel, a front face or a back face is formed as an inclined face 1c corresponding to a retaining wall slope face by changing the longitudinal directional length of the upper side or the lower side, the inclined face 1c of a retaining wall block 1 forming the other back face or front face as the vertical surface 1d is used so as to become the same plane as the retaining wall front face side, and plural pieces are heaped obliquely upward so as to become the retaining wall slope face. Or plural retaining wall blocks are heaped obliquely upward so that a back face of the blocks almost runs along a face of slope and a front face becomes a stairs shape, or the retaining wall blocks different in the brace length are heaped up so that the brace length becomes short as the blocks proceed to an upper stage, or concrete filling clearance 5 is arranged between the retaining wall blocks so that concrete is integrally filled in the vertically communicating filling clearance of the blocks stacked in a multistage shape.
