Claims

[Scope of utility model registration request]

In overflow type water gates that can be raised and lowered, one end of the upper end of the gate body is fixed on the downstream side and extends downward, gradually sloping toward the downstream side as it approaches the river bed, and the lower part is gently sloped. The gate is fixed in contact with the riverbed at the gate, and the roughly central part is attached to a coil spring whose one end is fixed to the lower part of the door body and receives a tensile force.The cross-sectional shape is not arched and is provided with a flexible rubber sheet. Low-noise water gate.
