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.
