PROBLEM TO BE SOLVED: To increase engagement force of a support concrete block and a wave-dissipating concrete block, so as to improve stability and wave-dissipating property of the wave-dissipating concrete block.;SOLUTION: On one end and another end respectively of an outer periphery of a body portion 11, the wave-dissipating concrete block 10 has three legs 12, 13, 14 and 15, 16, 17 projected at an angle of 120° to each other in the shaft direction of the body portion 11. The legs 12, 13, 14 of the one end are arranged so that their phases are displaced to the legs 15, 16, 17 of the other end at an angle of 60°. Accordingly, the engagement force (restraint force) of the wave-dissipating concrete block 10 and the support concrete block 18 is increased.;COPYRIGHT: (C)2010,JPO&INPIT
