PURPOSE:To eliminate the occurrence of cracking and separating phenomena by a method in which when laying blocks for permanent revetment on a sloped ground, iron bars are set in joint-packing parts formed around the adjacent blocks and then concrete is placed there. CONSTITUTION:When laying blocks 2 on a stepped part 6A, etc., leading to a slope or on the slope, iron bars 4 are set in a joint-packing part 3 formed around the adjacent blocks 2 and then concrete is placed there. Thus, since the joint parts are strengthened and the joints and the blocks are integrally joined with each other, the whole of the blocks covering the slope and stepped part can be more toughened. |
