WATERPROOF DOOR
PROBLEM TO BE SOLVED: To provide a waterproof door which hardly requires maintenance costs and which surely operates in a flood.SOLUTION: A waterproof door 30 includes: a storage body 21 whose upper side is open; a door body 22 which becomes a lid of the storage body 21 in a fall-down state at a normal time, and which stops water in a front and back direction in a standing state in a flood; and a water pressure cylinder 23 in which water supply/exhaust ports are provided at one end side 23a and the other end side 23b respectively, and which allows the door body 22 to rotate from a fall-down state to a standing state by water supply from one of the two water supply/discharge ports. It also includes: a tank 31 for storing water inside; a booster pump 32 for supplying water of the tank 31 to the water pressure cylinder 23 by applying pressure, and which circulates the water to the tank 31; and a plurality of valves 33A, 33B, 33C, 33D which switch the direction of water supply to the water pressure cylinder 23 and water discharge from the water pressure cylinder 23 by opening/closing.
【課題】メンテナンスの費用がほとんど掛からず、しかも洪水時に確実に動作する防水扉を提供する。【解決手段】上方が開口した収納体２１と、通常時には倒伏状態で収納体２１の蓋となるとともに、洪水時には起立状態で前後方向を止水する扉体２２と、一端側２３ａ及び他端側２３ｂにそれぞれ給排水口が設けられ、二つの給排水口のうちいずれか一方からの水の供給により扉体２２を倒伏状態から起立状態まで回動させる水圧シリンダー２３を備える防水扉３０において、内部に水を溜めたタンク３１と、圧力を掛けてタンク３１の水を水圧シリンダー２３に供給するとともにその水をタンク３１まで循環させる増圧ポンプ３２と、開閉して水圧シリンダー２３への給水及び水圧シリンダー２３からの排水の方向を切り替える複数のバルブ３３Ａ，３３Ｂ，３３Ｃ，３３Ｄを備える。【選択図】図１
