PROBLEM TO BE SOLVED: To provide a float mooring device that allows a float to move up and down in response to change in normal water level of a sea surface in ordinary times, and which is capable of floating the float on the sea surface even when the water level rises to an abnormal height due to the arrival of a huge tsunami, etc.SOLUTION: A pair of pedestal props 11 are fixed on the water bottom at suitable positions with respect to a floating pier 10, and the top end part of each pedestal prop 11 is provided with an oscillation prop 12, the tip end part of which is detachably supported, to mount end part of a coupling chain 13, one end part of which is fixed at the tip end part of the oscillation prop 12, on the bottom face of the floating pier 10. A total length of the oscillation prop 12 and the coupling chain 13 is increased above the height of a sea surface L on an abnormal sea level. On the abnormal sea level, the oscillation prop 12 stands up by a rise of the floating pier 10. In an ordinary time, the floating pier 10 moves up and down with change in water level due to tides under slacks and tensions of the coupling chain 13.SELECTED DRAWING: Figure 1
【課題】 平時には水面の通常の水位の変化に応じて浮体が昇降することを許容し、大津波の襲来等による異常な高さまで水位が上昇した場合でも水面に応じて浮体を上昇させて水面に浮遊させることができる浮体の係留装置を提供する。【解決手段】 浮桟橋10に対して適宜な位置の水底に一対の台座支柱11を固定し、該台座支柱11のそれぞれの上端部に着脱自在に先端部が支持される揺動支柱12を設け、該揺動支柱12の先端部に一端部を固定した連結チェーン13の他端部を浮桟橋10の下面に取り付ける。揺動支柱12と連結チェーン13の合計の長さを異常水位時の海面Lの高さよりも大きくする。異常水位時には浮桟橋10の上昇により揺動支柱12が起立しする。平時には、連結チェーン13の弛緩と緊張により干満により水位の変化に応じて浮桟橋10が昇降する。【選択図】 図1
