ERECTABLE FLAP GATE INSTALLED ON WATER BOTTOM
To provide an erectable flap gate allowing a lodged gate body to return to an erectable condition.SOLUTION: An erectable flap gate 1 is provided with a door body 2 and an anchoring part 31. The door body 2 is configured to be erected and/or lodging by a movable end part 24 which rotates around a support end part 23 as a supporting point arranged on a bottom of water. The anchoring part 31 anchors the door body 2 on the bottom of water. The door body 2 is provided with a first buoyancy cavity 25, a second buoyancy cavity 26, and a connecting part 27 for connecting buoyancy cavities. The first buoyancy cavity 25 is positioned between the movable end part 24 and the support end part 23. The second buoyancy cavity 26 is positioned between the first buoyancy cavity 25 and the support end part 23. The connecting part 27 for connecting the buoyancy cavities openably connects the first buoyancy cavity 25 to the second buoyancy cavity 26. When the door body 2 is anchored in an excessively lodged condition rather than in an anchored condition on the anchoring part 31, the connecting part 27 for connecting the buoyancy cavities is released. Thus, the door body 2 lodged from an erected condition is quickly returned to the anchored condition.SELECTED DRAWING: Figure 1
【課題】倒伏した扉体を速やかに起立可能状態に復帰させる。【解決手段】起伏ゲート１は、扉体２と、係留部３１とを備える。扉体２は、水底に配置された支持端部２３を支点として可動端部２４が回動することにより、起立および倒伏する。係留部３１は、扉体２を水底に係留する。扉体２は、第１浮力室２５と、第２浮力室２６と、浮力室接続部２７とを備える。第１浮力室２５は、可動端部２４と支持端部２３との間に配置される。第２浮力室２６は、第１浮力室２５と支持端部２３との間に配置される。浮力室接続部２７は、第１浮力室２５と第２浮力室２６とを開放可能に接続する。扉体２が係留部３１に係留される係留状態よりも倒伏した過倒伏状態において、浮力室接続部２７が開放される。これにより、起立状態から倒伏した扉体２を、速やかに係留状態へと復帰させることができる。【選択図】図１
