摘要： PURPOSE:To perform proper control of a delivery flow rate without needing artificial operation by arranging a water tank, in which a pressure is released, in the middle of a delivery water passage having a check valve located in an opening part to a delivery water tank, and arranging an overflow weir, the overflow depth of which is lower than a stop set water level of drain to the delivery water tank, at the water tank. CONSTITUTION:In a river drainage pump station, the delivery port of a pump 3 arranged in a suction water tank 1 is communicated with a delivery water tank 10 through a delivery water channel 2, and a check valve 4 is arranged in an opening part fronting on the delivery water tank 10 of the delivery water passage 2. The delivery water tank 10 is communicated with a river 12 through a communication water 11. In this case, a water tank 5 the delivery pressure of which is released to the atmosphere is located between the check valve 4 of the delivery water passage 2 and the pump 3 and an overflow weir 6 is arranged at a water tank 5. A portion situated downstream from the overflow weir 6 is communicated with a suction water tank 1 through a bypass water passage 7. When the water level W of a river 12 is raised to a level approximately equal to a set water level L, a part of the delivery water passage 2 is returned over the overflow weir 6 to the suction water tank 1.

摘要： PROBLEM TO BE SOLVED: To easily control the revolving speeds of prime movers and suppress the vibrations of a pump and a dust collector by forming the prime movers of a door body lifting means and the pump and the dust collector with hydraulic motors assembled in engine-driven hydraulic pump circuits. SOLUTION: An engine is driven to drive a hydraulic pump, a prime motor 4A for lifting or lowering a door body 1 is started, the door body 1 is lifted to open a gate, and the water of an upstream waterway 7 flows into a river 10. When the hydraulic pump is driven in the reverse direction by a controller, the door body 1 is lowered to close the gate. The backflow of the water of the river 10 into the upstream waterway 7 at the time of a flood can be prevented in cooperation with the closure of a flap valve 11. The hydraulic pump is driven to start prime movers 6D, 8B, a pump 6 is operated to discharge the water of the upstream waterway 7 into the river 10, and foreign matters is scraped up by a residue scraping rake 8A. The swelling of the upstream waterway 7 is suppressed, and the blocking of the pump 6 by foreign matter can be prevented.
