1 Project Overview Qingkou River tide gate located in Ganyu County, Jiangsu Province, Qingkou River mouth. The gate design flow 500m ~ 3 / s, check flow 600m ~ 3 / s. The total number of gate holes for the 7 hole, single hole net width of 5.0m, the floor along the flow direction of 14.0m long. The sluice chamber adopts the integral flat bottom plate structure, which is divided into three bottom plates, two holes on both sides are connected together, the middle three holes are connected together, the bottom plate surface elevation is -1.5m (bottom surface of the waste Yellow River, the same below), bottom plate elevation -2.7m . The downstream pier top elevation of 4.8m, the upstream side pier pier elevation of 3.0m. The upstream side of the gate has a net width of 4.5m, connecting the seawall on both sides with a bridge deck elevation of 5.9m.
