To construct a wave dissipation structure, in combination with a waste disposal site, in the offing of the sea while considering landscape in order to deal with giant typhoon, earthquake and tsunami.
A block reef B to be constructed in the offing is constructed by arraying and stacking tetrapod or heavy rubble toward the obliquely back side at a plurality of spots in the sea. Furthermore, at the seashore side, a wave dissipation box C is constructed in the similar array. Tsunami rides on the block reef B or the wave dissipation box C and moves forward while being branched to right and left, and its power is weakened little by little at each of the spots. Anchor piles F and f are driven through the block reef B or the wave dissipation box C, and grout is injected into the distal ends of the piles and the block reef B in the middle, thereby attaining reinforcement/scouring prevention. Further, after the block reef B and the wave dissipation box C are constructed completely, a breakwater reaching the seashore is constructed around or in the upper part of the block reef B and utilized as a reclamation site or remaining material storage space.
