LIFTING GATE TYPE BREAKWATER
To speed up a standing start operation of a door body while keeping a gap between the door body and a storage portion small.SOLUTION: A lifting gate type breakwater 1 comprises: a door body 10 provided underwater and rotating from a fallen state around a rotation shaft 11 at a base end side by buoyance to stand; a storage portion 20 which is provided under the door body 10 in the fallen state and in which the door body 10 is stored; and a water supply mechanism 40 having a water storage chamber 41 and supplying water in the water storage chamber 41 to an inner space 24 of the storage portion 20 according to a start of standing of the door body 10.SELECTED DRAWING: Figure 3
【課題】扉体と格納部との隙間を小さくしつつも、扉体の起立開始動作を速くすること。【解決手段】起伏ゲート式防波堤１は、水中に設けられ、倒伏状態から浮力によって基端側の回動軸１１を中心に回動し起立する扉体１０と、倒伏状態の扉体１０の下方に設けられ、扉体１０が格納される格納部２０と、貯水室４１を有し、扉体１０が起立を開始するに伴い、貯水室４１の水を格納部２０の内部空間２４に供給する水供給機構４０とを備えている。【選択図】図３
