摘要

(Problem) The natural stone stacking construction is made easy, and even if the natural stone stacking construction is carried out, it is possible to construct a safe and solid civil engineering structure.;(Solution means) Construction stone for civil construction 1 in which the proximal end 4a of the rod-like member 4 is integrated with the natural stone 2 and the washer 7 is provided at the distal end 4b of the rod-shaped member 4. Prepare. Then, using a plurality of such construction stones (1) for civil engineering structures, the respective natural stones (2) are stacked one by one, and the respective rod-shaped members (4) are arranged almost in parallel, The rod-shaped member 4 and the washer 7 are embedded with the earth and sand 13 to secure a large friction force between the earth and sand 13 and the washer 7 and the like.
