京杭运河口门低等级老船闸扩容改造研究

针对京杭运河苏北段沿线低等级口门船闸规模较小、周边限制性因素较多、工程防洪等级较高、船闸设计水头较高且常水头与设计水头相近的特点,宝应船闸扩容改造工程中,通过合理进行平面布置,采用闸墙廊道短支孔分散输水系统,优化上下游引航道结构型式等工程措施,提高了船舶过闸效率,改善了船舶泊稳条件,取得了良好的工程效果。

Countermeasure & Research of the Broadening of the Old Lock

Aimed at these similar characteristics of the low-grade entrance ship lock on the Grand Canal of Northern Jiangsu section: smaller scale,surrounding restricted by many factors,higher level of flood protection works,design head higher and constant head similar to the design head.Baoying ship lock broadening project use such engineering measures as reasonable layout,using short branch dispersed filling and emptying system,optimization the upstream and downstream approach channel structure and other engineering measures,to improve the passing efficiency,guarantee the berthing condition of ships in the lock chamber.It may provide some useful reference for future similar ship lock broadening practices.
