小清河水牛韩省水船闸输水系统布置及水力计算

水牛韩船闸是小清河复航工程的上游梯级,由于沿线水资源比较匮乏,水牛韩船闸须具备省水功能。根据闸址地形条件并考虑未来船闸续建的需求,提出单级省水池的水牛韩省水船闸总体布置。按照《船闸输水系统设计规范》要求和工程特点,确定水牛韩船闸采用闸首短廊道集中输水系统,省水池与上、下闸首分别用一根输水廊道连接的输水系统,提出具体的输水系统布置,确定各输水阀门运行方式,并采用船闸输水过程数学模型计算了船闸非省水运行和省水运行时的输水水力特性。结果表明,提出的输水系统布置和确定的输水阀门运行方式合理可行,各输水水力特性值满足设计和规范要求。

Layout and hydraulic calculation of filling and emptying system for Shuiniuhan water-saving ship lock of Xiaoqing River

Shuiniuhan ship lock is the upstream step of re-navigable project of Xiaoqing River.Due to the lack of water resource along the re-navigable project of Xiaoqing River,Shuiniuhan ship lock should need water-saving function.According to the topographical conditions of the lock site and considering the need for the future construction of the ship lock,we propose the overall layout of the Shuiniuhan ship lock with a single-level water-saving pool.In accordance with the requirements of Design Code for Filling and Emptying System of Ship and the characteristics of the re-navigable project of Xiaoqing River,we put forward the type of lock head filling and emptying system of Shuiniuhan ship lock to be short-culvert concentrated,connect the water-saving pool to the upper and lower lock head by a water conveyance corridor respectively,determine the detailed layout of the filling and empting system and the valve opening mode,and calculate hydraulic characteristics during lock filling and emptying with non-water-saving and water-saving operations by lock filling and emptying mathematical model.The results show that the detailed layout of the filling and empting system and the valve opening mode are reasonable,the hydraulic characteristics can satisfy the design and criteria demands.
