TIDE GATE AND TIDE GATE INSTALLATION METHOD
PROBLEM TO BE SOLVED: To provide a tide gate capable of automatically shutting off.SOLUTION: A tide gate 1 which is provided to a breakwater 50 includes: a rotation axis 2 which is disposed along a vertical direction; and a door body 3 the base end of which is supported by the rotation axis 2 to rotate on the rotation axis 2 to thereby shut a gate 51 formed in the breakwater 50. The tide gate 1 also includes: side walls 4a which is disposed at the opposite side of the gate 51 relative to the door body 3 being separated a predetermined distance from the door body 3 protruding from the breakwater 50 along the door body 3 in an open state with the front end of the door body 3 at the upstream side in a water flow direction in the gate 51; and seal walls 4b for sealing the base end side of the door body 3 formed continuously with the side wall 4a of the breakwater 50.
【課題】門を自動的に閉鎖すること。【解決手段】防波堤５０に設けられる防波扉１であって、鉛直方向に沿って配置された回転軸２と、回転軸２に基端が支持されて回転軸２の廻りに回転移動することで防波堤５０に設けられた開状態の門５１を閉鎖する扉体３とを含み、門５１における水の流入方向の上流に扉体３の先端を向けて配置した開状態で、扉体３における門５１の反対側に扉体３と所定間隔を隔てて扉体３に沿って防波堤５０から突出して配置される側壁４ａ、および側壁４ａに連続して防波堤５０において扉体３の基端側を塞ぐ閉止壁４ｂを備える。【選択図】図３
