To provide a breakwater for tsunami that prevents a tsunami from directly hitting ocean airports, coastal complexes or the like when the tsunami attacks the inside of a harbor.SOLUTION: A caisson 1 filled with iron ores or crushed rocks 4 inside is installed in front of an ocean airport or a coastal area that needs to be protected from a direct hit of a tsunami. A wall type breakwater 3 whose inside is solidified with concrete is installed continuously in front of the caisson 1. The wall type breakwater 3 has a height that prevents a tsunami from passing over the breakwater and that can hold the tsunami, and the width of the breakwater is greater than that of the caisson 1. Also, the wall type breakwater 3 can resist the force of a tsunami by means of a pile 5 driven into the seafloor from the bottom of the breakwater. A caisson 2 that has the substantially same height as or is slightly smaller in height than the one installed in the rear is installed in front of the wall type breakwater 3. The caisson 2 serves to prevent the lower part of the breakwater from being raised to the front when the upper part receives a tsunami.SELECTED DRAWING: Figure 2
【課題】港湾内に津波が来襲したとき海上空港や臨海部のコンビナートなどへの津波の直撃を防止する津波用防波堤を提供する。【解決手段】津波の直撃を阻止したい海上空港や臨海部の前面に、鉄鉱石や砕石４を内部に詰めたケーソン１を設置し、そのケーソン１の前面に津波が越えるのを阻止し、かつそれを貯えるだけの高さがあり、幅はケーソン１より広く、かつその底から海底に打ち込んだ杭５で津波の力に対抗できかるようにした内部をコンクリートで固めた壁型の防波堤３を連続して設置し、壁型の防波堤３の前面にも、上部が津波を受けたときに下部が前方に跳ね上がることを抑える役割を果たす、後方に設置したものとほぼ同じかまたは少し低いケーソン２を設置する。【選択図】図２
