输水系统是船闸实现其功能的关键设施,其设计直接影响船闸工程的安全与效率。等惯性四区段出水分散输水系统是目前国内外高水头大型船闸常用的输水系统形式,但其结构复杂、建设难度大,且由于设置第二分流口而带来自身空化等问题。为解决上述问题,结合我国内河船闸特点,通过国内外工程资料分析、理论与计算分析、物理模型试验等手段,提出并验证了“闸墙长廊道+闸室中心立体分流+闸底两区段四纵支廊道出水+侧支孔+明沟消能”的等惯性两区段输水系统形式在40 m级单级巨型船闸中的适用性,为高水头大型船闸建设提供参考和依据。
The water delivery system is the key facility for the ship lock to realize its function. Its design directly affects the safety and efficiency of the ship lock project. The inertial four-zone water distribution and dispersion system is the most commonly used form of water delivery system for high-head and large-sized shiplocks both at home and abroad. However, its structure is complex and the construction is difficult, and cavitation is caused by the second diversion opening. In order to solve the above problems, combined with the characteristics of inland river locks in our country, through the analysis of engineering data at home and abroad, theoretical and computational analysis, physical model tests and other means, proposed and verified The applicability of two isokinetic two-stage water conveyance system forms in the 40 m-class single-stage gigantic ship lock for section four vertical branch corridor water outlet + side branch hole + open channel energy dissipation "is provided for reference for the construction of large headlocks with high water head and in accordance with.
