Layout of water-saving pool and water conveyance system for water-saving ship lock
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.
