摘要
根据洪江船闸扩建改造工程条件,确定采用闸底长廊道侧支孔出水明沟消能输水系统。由于布置在老船闸基础上进行,有别于一般新建船闸,具有其特殊性和复杂性。通过1:25的输水系统水力学物理模型试验,研究优化充水阀门单边运行方式为单边间歇开启,改善单边输水水力特性;通过在进水口前设置消涡板,消除进水口处的串心旋涡。
According to the conditions of the expansion and reconstruction of Hongjiang shiplock,the filling and emptying system was arranged with chamber floor′s long culvert and later orifice.Because of the limitation of the old chamber,the arrangement of the filling and emptying system of Hongjiang reconstructive lock was special.A 1:25 physical model was set up for meeting the requirements of the design code.The vortex elimination plate is set in front of the inlet to eliminate the cascade vortex at the inlet.At the same time,by optimizing unilateral operation mode of water filling valve to open intermittently,the hydraulic characteristics of unilateral water conveyance can be improved.
