MOVABLE BREAKWATER AND MOVABLE BREAKWATER FACILITY
PROBLEM TO BE SOLVED: To keep an arrangement state of an air feed pipe.SOLUTION: A movable breakwater 10 comprises: an outer cylindrical pipe 11 that is formed to be long in the vertical direction, has an opening 11a on the water bottom side, and is inserted and fixed into the water bottom ground E; a floating pipe 12 that is inserted into the inside of the outer cylindrical pipe 11, is arranged so as to be movable upward and downward in the longitudinal direction of the outer cylindrical pipe 11, and is provided so as to be capable of rising by buoyancy generated by a gas supplied to the inside of the floating pipe 12; and an air feed pipe 3 for supplying the gas to the inside of the floating pipe 12. The outer cylindrical pipe 11 has: a guide part 11A positioned outside the outer cylindrical pipe 11 to form a space which vertically continues from the top end of the outer cylindrical pipe 11, whose top part 11Aa is open, and whose bottom part 11Ab is closed; and an opening hole 11B which is positioned at the closed bottom part 11Ab of the guide part 11A and makes the space of the guide part 11A communicate with the inside of the outer cylindrical pipe 11. The air feed pipe 3 is inserted from an opening of the top part 11Aa of the guide part 11A before a tip 3A reaches the bottom part 11Ab and is inserted into the opening hole 11B. The tip 3A has an engaging part 3C for engaging with a marginal part of the opening hole 11B.
【課題】送気管の配置状態を維持すること。【解決手段】上下に長尺に形成され、水底側に開口部１１ａを有して水底地盤Ｅ内に挿入固定された外筒管１１と、外筒管１１の内部に挿入され、外筒管１１の長手方向に昇降移動可能に配置されるとともに、自身の内部に供給された気体により浮力を生じて上昇可能に設けられた浮上管１２と、浮上管１２の内部に気体を供給する送気管３とを備える可動式防波堤１０において、外筒管１１は、その外側に上端から上下方向に連続して上部１１Ａａが開口し底部１１Ａｂが閉塞された空間を形成するガイド部１１Ａと、ガイド部１１Ａの閉塞された底部１１Ａｂの位置でガイド部１１Ａの空間から自身の内部に通じる開口穴１１Ｂとを有しており、送気管３は、ガイド部１１Ａの上部１１Ａａの開口から挿入されて先端部３Ａが底部１１Ａｂに至り開口穴１１Ｂに挿入され、当該先端部３Ａに開口穴１１Ｂの縁部に係止される係止部３Ｃを有する。【選択図】図１０
