Title:
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
Document Type and Number:
Japanese Patent JP7093560
Kind Code:
B2
Abstract:
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
