TSUNAMI ATTENUATION GROOVE STRUCTURE
PROBLEM TO BE SOLVED: To provide a groove structure which can reduce height and strength of tsunami and is provided on the sea bottom.SOLUTION: An inclined wall surface 4 on a land side more upright than a sea bottom 1 is inclined to an offshore side toward a sea surface 2, and is curved into a recessed shape. A cavity portion 5 for adjusting buoyancy so as to obtain buoyancy larger than the total weight of a groove structure is provided, an air supply/exhaust plug 7 for adjusting buoyancy is provided above the cavity portion 5 for adjusting the buoyancy, and a sea water entrance 6 is provided below the cavity portion 5 for adjusting the buoyancy. A rod 10 is erected above the sea surface 2 from both ends of the groove structure.SELECTED DRAWING: Figure 1
【課題】津波の高さおよび強さを低減させることのできる海底に設ける溝構造体を提供する。【解決手段】海底１よりも立ち上がった陸地側の傾斜した壁面４を海面２に向かうに従って沖側に傾け、凹形に湾曲させる。溝構造の総重量よりも大きい浮力を得るように浮力を調節する空洞部分５を設け、浮力を調節する空洞部分５の上方に浮力調整用空気送排気栓７を設け、浮力を調節する空洞部分５の下方には海水出入り口６を設ける。溝構造体の両端部から海面２の上方に竿１０を立ち上げる。【選択図】図１
