PROBLEM TO BE SOLVED: To provide a construction method of a V-shaped drain gutter and construction blocks to facilitate the separation and demolition in the case of demolition in a trench on the ground surface excavated in a V-shape. SOLUTION: The blocks 1 and 1A formed in a chevron-shape (shown in Fig.) are made as bilateral symmetry to join together at the bottom section of the trench T in the trench on the ground surface excavated in a V-shape, at the same time, the blocks are consecutively joined together in the longitudinal direction, and a joint section is hardened with joint adhesives 2 and 6 to construct the V-shaped drain gutter having flat edge sections 3 and 3a on both sides.
