WATERTIGHT STRUCTURE FOR FLAP GATE AND FLAP GATE PROVIDED WITH THE SAME
To provide a watertight structure for flap gate and a flap gate provided with the same which can largely take a gap between a door body and a bottom surface of a water gate opening without providing a step in a state where an external force other than gravity is not applied, and can secure watertightness with the water gate opening in closing.SOLUTION: In a watertight structure in a flap gate 1 provided with a door body 2 which is supported in such a weight balance as to open an opening 200 of a water gate 100 in a state where an external force other than gravity is not applied, a gap C is provided between a lower end edge part 23 of a door body 2 and a bottom surface 300 of a water gate 100 in a state where the door body 2 closes the water gate 100, and the watertight structure has a gap opening/closing member 72 that is slid in a running water direction and opens/closes the gap C.SELECTED DRAWING: Figure 1
【課題】 重力以外の外力が加わらない状態において、敷段差を設けなくても扉体と水門開口部の底面との間の隙間を大きく取ることができるとともに、閉鎖時には水門開口部との水密性を確保することのできる、フラップゲート用水密構造体およびこれを備えたフラップゲートを提供する。【解決手段】 重力以外の外力が加わらない状態で水門１００の開口部２００を開口する重量バランスで支持されている扉体２を備えたフラップゲート１における水密構造体であって、扉体２が水門１００を閉鎖している状態において扉体２の下端縁部２３と水門１００の底面３００との間に隙間Ｃを設けるとともに、流水方向に揺動して隙間Ｃを開閉する隙間開閉部材７２を有する。【選択図】 図１
