PROBLEM TO BE SOLVED: To provide a construction technology for an undersea structure suppressing water level rise on a seashore side, reducing wave height, and having an excellent coastal conservation function.SOLUTION: A block 100 comprises: a body part 10 having an equilateral triangle shape in a planar view; an opening 11 provided in a region including the center of gravity of the body part 10; and three support parts 12 protrusively formed at apexes of the bottom face of the body part 10, respectively. On a submerged breakwater 200 formed in the sea near a coast, a plurality of blocks 100 are arranged along an extension direction L of the submerged breakwater 200 at predetermined intervals in the state that the body part 10 represents an equilateral triangle shape in a planar view and one of peripheral edges 13 of the body part 10 is parallel to the extension direction L of the submerged breakwater 200, and an undersea structure 300 is formed by housing crushed stones R in the openings 11 of the blocks 100. |
