SUCTION ANCHOR
PROBLEM TO BE SOLVED: To lift extraction resistance force against tensile force without making a scale large.SOLUTION: A suction anchor 1 according to the present invention generally consists of a peripheral wall part 2, a top plate part 3 closing an upper end thereof, a cylinder-shaped cell 4 provided nearby the top plate part, and a disk-like bearing pressure plate 8 which is arranged in the cell and to which a tension rod 9 has its lower end coupled. The bearing pressure plate 8 is so arranged as to move in the cell 4 reciprocally along a substantially perpendicular direction, and the inner space of the cell is sectioned liquid-tightly into an upper space 14 spreading between a lower surface of the top plate part 3 and an upper surface of the bearing pressure plate 8 and a lower space 15 spreading between a lower surface of the bearing pressure plate 8 and a ground surface 45 of the seabed 13. In the upper space 14 of the cell 4, a coil spring 16 is arranged as an elastic member allowing restoring force to operate on the upper surface of the bearing pressure plate and the lower surface of the top plate part 3 as the bearing pressure plate 8 is elevated.SELECTED DRAWING: Figure 1
【課題】規模を大きくせずとも、引張力に対する引抜き抵抗力を引き上げる。【解決手段】本発明に係るサクションアンカー１は、周壁部２、その上端を塞ぐ天板部３、該天板部の近傍に設けられたシリンダー状の隔室４、及び該隔室内に配置され引張ロッド９がその下端で連結された円板状の支圧板８で概ね構成してある。支圧板８は、隔室４内をほぼ鉛直方向に沿って往復動自在となるように配置してあるとともに、該隔室の内部空間を、天板部３の下面と支圧板８の上面との間に拡がる上方空間１４と、支圧板８の下面と海底地盤１３の地盤面４５との間に拡がる下方空間１５とに水密に区画してある。隔室４の上方空間１４には、支圧板８の上昇に伴って該支圧板の上面及び天板部３の下面に復元力を作用可能な弾性部材としてのコイルスプリング１６を配置してある。【選択図】 図１
