LAND TYPE FLAP GATE
PROBLEM TO BE SOLVED: To dispense with removal of a water cutoff membrane for blocking up mutual door bodies, when inspecting floatation confirmation of a standing start and operation confirmation between a falling-down state and a standing state.SOLUTION: A land type flap gate 11 is provided by juxtaposing and connecting a plurality of door bodies 13 standing-rocking on the tip side in a row with the rear end side as a fulcrum 13a. One end of a rope 14 is installed in a rear end part of the door bodies 13, and the other end is installed in a counterweight 17. The counterweight 17 becomes the lowest point in the middle of standing or falling-down of the door bodies 13, and while assisting the standing or the falling-down when starting the standing or the falling-down, standing blocks 16a and 16b for guiding the rope 14 are installed under the rear end side of the door bodies 13 so as to act as resistance of the standing or the falling-down before completing the standing or the falling-down. A water cutoff membrane 20 for water-tightly blocking up the mutual adjacent door bodies 13 is formed as a trapezoidal shape of gradually expanding in a width toward the tip side from the rear end side of the door bodies 13. The present invention can be constructed regardless of the length between diameters, and can confirm floatation of a standing start only by suspending a floatation confirming inspection weight at a door body rear end part.
【課題】起立開始の浮上確認や、倒伏状態と起立状態間の動作確認の検査時に、扉体間を塞ぐ止水膜の取外しを不要とする。【解決手段】後端側を支点１３ａとして先端側が起立搖動する複数の扉体１３を一列に並べて連結した陸上型フラップゲート１１である。ロープ１４の一端を扉体１３の後端部に、他端をカウンタウエイト１７に取付ける。扉体１３の起立又は倒伏途中でカウンタウエイト１７が最下点となり、起立又は倒伏開始時には起立又は倒伏を補助する一方、起立又は倒伏完了前には起立又は倒伏の抵抗として作用するよう、扉体１３の後端側下方にロープ１４を案内する固定滑車１６ａ，１６ｂを設置する。隣接する扉体１３間を水密状に塞ぐ止水膜２０を、扉体１３の後端側から先端側に向かって幅が漸次拡大する台形状とする。【効果】径間の長短によらず構築が可能で、扉体後端部に浮上確認点検用ウエイトを吊り下げるだけで、起立開始の浮上を確認できる。【選択図】図１
