一、工程概况 三河闸位于江苏省洪泽县境内,为淮河下游入江水道的控制工程,它与洪泽湖大堤和二河闸、高良涧进水闸等工程构成一体,成为苏北里下河地区的防洪屏障。该闸系钢筋混凝土结构,全闸63孔,每孔净宽10米,总宽697.75米,闸门系弧形钢闸门,由2×150kN卷扬式启闭机控制,设计流量12000立方米每秒。建闸40余年来,已安全行洪8500亿立方米,发挥了巨大的工程效益和社会效益。
First, the project profile Sanhe gate is located in Hongze County, Jiangsu Province, as the Huaihe River into the waterway control project, which with the Hongze Lake embankment and the Erhe floodgate into the sluice and other projects into a whole, a northern Lixiahe area Flood barrier. The gate reinforced concrete structure, full gate 63 holes, each hole net width of 10 meters, a total width of 697.75 meters, the gate of the arc-shaped steel gate, by 2 × 150kN winch hoist control, the design flow of 12,000 cubic meters per second. After more than 40 years of construction of the sluice gate, it has safely flooded 850 billion cubic meters and exerted tremendous engineering and social benefits.
