LAYING BLOCK, AND SUCTION PREVENTIVE STRUCTURE FOR LAYING BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a laying block favorable to the ecosystem and excellent in execution property. SOLUTION: Concrete block single bodies 2 stacked on the vertical direction are juxtaposed in the transverse direction, and a longitudinally communicable gap 15 is provided between the block single bodies 2 and 2 adjacent to each other. The block single bodies 2 and 2 are connected to each other via a connection member 3. Since a plurality of block single bodies are connected to each other via the connection member 3, a plurality of block single bodies 2 can be stably installed at one time if one laying block 1 is installed. Since the gap 15 free from any concrete is formed between the block single bodies 2 and 2 adjacent to each other in the laying blocks 1 arranged in stages, a retaining wall excellent in adaptability to the ecosystem can be obtained.
