红水河乐滩船闸输水系统水力特性原型调试研究

Study by prototype debug on hydraulic characteristics of the filling and emptying system of Letan ship lock on Hongshui River

红水河乐滩船闸是国内实际运行水头最高的单级船闸.本文介绍了该船闸双边输水工况水力特性,提出了控制闸室超灌(泄)的措施,并通过输水方式优化,改善了闸室水流流态,保证了船闸安全通航.

Letan ship lock is a single-lift ship lock which has the highest factual working head in China. This paper presents the hydraulic characteristics under operating conditions with double-valve operation, and puts forward the measures for controlling the inertia over travel. By optimizing the pattern of water conveyance, the flow regime in the chamber has been ameliorated, and the safety of the navigation has thus been guaranteed.
