1 工程概况刘庄引黄闸,位于山东省菏泽市,在黄河右岸大堤桩号221+080处,为3孔桩基开敞式水闸,孔口高4m、宽6m,闸底板高程为55.20m,设计引水流量80m~3/s,加大引水流量150m~3/s,设计灌溉面积6.4万hm~2。该闸1979年10月建成并开始运行。1993年,为减少灌区渠系泥沙淤积,在闸前75m处修建橡皮坝,另外闸下游230m处是灌区分水闸。1999年前,该闸只有一台双吊点行走式启闭机,每次只能提起或关闭一孔
1 Project Overview Liuzhuang cited the Yellow River Gate, located in Heze City, Shandong Province, on the right bank of the Yellow River embankment stake 221 + 080, for the 3-hole open-pored foundation sluice, orifice height 4m, width 6m, sluice floor elevation 55.20m , Design diversion flow 80m ~ 3 / s, increase diversion flow 150m ~ 3 / s, design irrigation area 64000 hm ~ 2. The gate was completed and started operation in October 1979. In 1993, to reduce the sediment deposition in the irrigation canal system, a rubber dam was built at a depth of 75m before the gate. In addition, a flood gate was opened at 230m downstream of the gate. Before 1999, the gate had only one double-lift point hoist, each time can only lift or close a hole
