PROBLEM TO BE SOLVED: To construct a revetment that hardly collapses overall, by strengthening a bond between adjacent revetment construction blocks without extremely increasing weight.;SOLUTION: Engaging structures K1, K2 are formed that comprise a recess 10 (20) and a protrusion 11 (21), on each side surface of an upper portion (an apex angle α1 side) and a lower portion (an apex angle α2 side). The engaging structure K1 of the upper portion is set to have the protrusion 11 positioned on the bottom and the recess 10 on the top. The engaging structure K2 of the lower portion is set to have the protrusion 21 on the top and the recess 20 on the bottom. Each of the engaging structures K1, K2 of the upper portion and the lower portion is formed to be roughly V-shaped, by being formed on a pair of side surfaces corresponding to two sides that form the apex angle, when seen in a planar view. The protrusion 21 of a block B placed on top is engaged by overlapping from above with the protrusion 11 of the block B placed on bottom.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
