超高水头大型船闸输水系统研究

Research on water conveyance system of large ship lock with super-high head

随着社会经济的发展和技术的提高,船闸不断向大型化和高水头化方向发展,以往常规的等惯性输水系统已不能适应40 m以上的超高水头大型单级船闸。结合某工程实例,通过类比分析、物理模型试验及数值计算的方法,提出了新型自分流的闸室分流口结构型式和输水系统布置型式,很好地解决了闸室高效输水和船舶停泊安全问题,显著拓展了常规等惯性输水系统的适应性,其成果可供超高水头大型船闸设计借鉴。

With the development of social economy and improvement of technology,the ship lock is constantly developing towards maximization and high head. Practices show that the past conventional dynamical balanced system can not fulfill the demands of the super-high single-level ship lock over 40 m. Combined with an engineering example,a new structure form of selfdiffluence diversion outlet and a water conveyance system is put forward,which can effectively solve the problem of high efficiency water conveyance and ship berthing safety in lock chamber. The research results expand the adaptability of conventional inertial water system and can be a reference for super-high ship lock design.
