FLOATING FLAP GATE
PROBLEM TO BE SOLVED: To arbitrarily set a water level at which a door body starts to rise.SOLUTION: A floating flap gate 1 is configured to raise and move a tip of a door body 2 around a rotation axis 2c located at a base end in a direction of water flowing in, and in a plane in a height direction, in order to close an opening of a tide barrier or a breakwater when the water flows in. A counterweight 7 is fixed at the other end of a wire rope 4 having one end fixed to a tip 2b of the door body 2. A stopper 8 is fixed to the wire rope 4 located between the door body 2 and a pulley 6a for guiding first the wire rope 4 fixed to the tip 2b of the door body 2. The wire rope 4 located between the stopper 8 and the door body 2 passes through a hollow first buoyance body 9 so as to be relatively displaced with respect to the wire rope 4. The door body is kept horizontal for a vehicle or the like to travel or evacuate at a water level where the vehicle or the like can travel.
【課題】扉体の起立開始水位を任意に設定できるようにする。【解決手段】水が流入する際、防潮壁や防波堤の開口部を遮断するために、流入する水の方向に高さ方向の平面内で、扉体２の先端側が基端側の回転軸２ｃを支点として起立揺動する浮体式フラップゲート１である。扉体２の先端部２ｂに一端を取付けたワイヤロープ４の他端にカウンタウエイト７を取付ける。扉体２の先端部２ｂに取付けたワイヤロープ４を最初に案内する滑車６ａと扉体２の間に位置するワイヤロープ４にストッパ８を固定する。ストッパ８と扉体２の間に位置するワイヤロープ４に、ワイヤロープ４に対して相対移動が自在なように中空形状の第１の浮力体９を通す。【効果】自動車等が走行可能な水位では扉体の倒伏状態を維持して、自動車等の通行や避難が可能になる。【選択図】図１
