MOVABLE BREAKWATER AND MOVABLE BREAKWATER FACILITY
PROBLEM TO BE SOLVED: To provide a movable breakwater ensuring rapid flotation of a floating pipe.SOLUTION: A movable breakwater comprises: an outer cylindrical pipe 11, which has an opening 11a on a water bottom side and vertically extends from a water bottom surface GL into a water bottom ground E; a floating pipe 12, which is inserted into the outer cylindrical pipe 11 from a lower end 34 and moves up from inside of the outer cylindrical pipe 11 due to buoyance generated by gas supplied into the floating pipe 12 itself; a lid 17a, which is installed on an upper end 32a of the floating pipe 12 and extends beyond an inner peripheral part 38 of the outer cylindrical pipe 11 in a direction perpendicular to a longer direction of the floating pipe 12; and a wall 19a, which is placed on the lower end 34 side and outside of a periphery 43 of the floating pipe 12 and extends from the upper end 32a toward the lower end 34.
【課題】可動式防波堤において、浮上管の浮上を迅速かつ確実にすること。【解決手段】水底側に開口部１１ａを有し、水底面ＧＬから水底地盤Ｅ内に向かって上下に延伸する外筒管１１と、下端部３４から外筒管１１の内部に挿入され、かつ、自身の内部に供給された気体により浮力を生じて外筒管１１の内部から上昇する浮上管１２と、浮上管１２の上端部３２ａに取り付けられて、外筒管１１の内周部３８よりも、浮上管１２の長手方向と直交する方向の外側に延伸する蓋１７ａと、蓋１７ａの下端部３４側、かつ浮上管１２の外周部４３よりも外側に設けられて、上端部３２ａから下端部３４に向かって延伸する壁１９ａと、を含む。【選択図】図６
