FLOATING BODY TYPE FLAP GATE
PROBLEM TO BE SOLVED: To install even a door body of a long span unable to provide a ground structure in an intermediate part.SOLUTION: A floating body type flap gate 1 is constituted so that the tip side 2b of a door body 2 can stand and rock with a rotary shaft 2c on the base end side 2a as a fulcrum in a plane in the height direction in the flowing-in water direction. The other end of a wire rope 4 whose one end is fixed to a reverse surface 2d of the door body 2 existing in a falling-down state, is fixed to a ceiling part of an underground space 5a by being guided via fixed pulleys 7a and 7b and movable pulleys 8a and 8b arranged inside the underground space 5a formed on the tip part side of the door body 2 of a storage space 5 for storing the fallen-down door body 2. Push-up on the tip side of the door body 2 of the standing initial stage and sudden falling-down of the falling-down final stage are restrained by lifting a push-up rod 9 for installing the first movable pulley 8a by lifting of a counterweight 6 for installing the second movable pulley 8b for guiding the wire rope 4, and shock absorption of the standing final stage and water-level tracking of the falling-down initial stage are executed by tension acting on the wire rope 4.SELECTED DRAWING: Figure 1
【課題】中間部に地上構造物を設けることができない径間が長い扉体であっても設置を可能とする。【解決手段】流入する水の方向に高さ方向の平面内で扉体２の先端側２ｂが基端側２ａの回転軸２ｃを支点とする起立揺動可能に構成した浮体式フラップゲート１である。倒伏状態にある扉体２の裏面２ｄに一端を固定したワイヤロープ４の他端を、倒伏した扉体２を格納する格納空間５の、扉体２の先端部側に形成した地下スペース５ａの内部に配置した定滑車７ａ，７ｂと動滑車８ａ，８ｂを介して案内して地下スペース５ａの天井部に固定する。ワイヤロープ４を案内する第２の動滑車８ｂを取り付けたカウンタウエイト６の昇降により、第１の動滑車８ａを取り付けたプッシュアップロッド９を昇降させて起立初期の扉体２の先端側の押し上げと倒伏終期の急激な倒伏の抑制、ワイヤロープ４に作用する張力により、起立終期の衝撃吸収と倒伏初期の水位追従を行う。【選択図】図１
