摘　　要：相比于常规船闸,省水船闸的省水池设计对输水系统的布置产生怎样的影响,阀门启闭次数翻倍、工作水头降低对输水时间的延长是否可控是关键的问题。通过水力计算和三维水流数学模型试验的方法对马店船闸省水池及输水系统进行研究,提出“闸底长廊道侧支孔”+“一级省水池”组合的创新型输水系统形式,其输水时间能够满足“设计输水时间不大于10 min”的要求,省水运行对船闸输水效率的折减符合设计预期,水流平稳,输水系统布置和省水池布置合理。Compared with the conventional ship lock,there are some critical issues for water-saving ship lock,such as how does the design of the water-saving pool affect the layout of the water conveyance system of the ship lock,and whether the doubling of the number of valve opening and closing times and the reduction of the working head can control the extension of the water conveyance time.In this paper,the water-saving pool and water conveyance system of the Madian ship lock are studied by means of hydraulic calculation and three-dimensional water flow digital model test,and an innovative water conveyance system type combining“side branch hole of the sluice bottom corridor”+“first-class water-saving pool”is proposed.The water conveyance time of this water conveyance system can meet the requirements of“the design water conveyance time is not more than 10 min”,and the reduction of the water conveyance efficiency of the ship lock by the water-saving operation is in line with the design expectations.The water flow is stable,and the layout of the water conveyance system and the water-saving pool are reasonable.
