Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable maintenance of outflow rate even when dusts accumulated on water inlet, and facilitate removal of the accumulated dust.SOLUTION: A water discharge facility of the present invention is installed on a dam body, and includes a water storage section for storing a part of water dammed by the dam body, and a water discharge channel for discharging the water dammed in the water storage section toward a downstream side of the dam body. The water storage section causes stored water flow over the dam body when the water storage volume exceeds a water storage capacity. The water discharge channel includes a water inlet for taking in water from the water storage section, an outlet for discharging the water taken in toward the downstream side of the dam body, and a cover for opening/closing the outlet. The cover opens the outlet when a pressure of water taken in is higher than a prescribed water pressure value, and closes the outlet when the water pressure is lower than a prescribed water pressure value.SELECTED DRAWING: Figure 1
