WATER DISCHARGE FACILITY
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
【課題】取水口に塵芥が付着した場合でも、放流量を維持することができ、しかも、付着した塵芥を容易に除去できるようにする。【解決手段】本発明の放水設備は、堤体に設けられ、堤体によって堰き止められた水の一部を貯水する貯水部と、該貯水部に貯水された水を堤体より下流側へ放流する放流路と、を備え、貯水部は、貯水量が貯水可能量を超えた場合に、貯水が堤体から越流するように構成され、放流路は、貯水部の水を取り込むための取水口と、取り込んだ水を堤体の下流側へ放流する放水口と、放水口を開閉可能に構成された蓋とを備え、蓋は、取水口より取り込んだ水の水圧が所定圧より高い場合には、放水口を開放し、所定圧より低い場合には、放水口を閉塞するよう構成されている。【選択図】図１
