赣州市章江水闸除险加固设计要点回顾

Review on the main points of danger removal and reinforcement design of Zhangjiang sluice in Ganzhou

赣州市章江水闸是一座大(1)型水闸工程,加固工程于2021年通过竣工验收。工程加固设计中,针对该水闸的特点及存在的问题,通过优化水闸枢纽总体布置,在南、北岸电站左侧分别扩孔建泄洪闸,显著提高了泄洪能力;通过优化水闸调度方式,结合加固原消力池、新建二级消力池、新建钢筋石笼海漫等多种措施,根本解决了消能防冲问题。鉴于水闸加固后取得了非常良好的效果,本文对主要设计技术方案进行了回顾与总结,以期对同类型项目设计提供参考。

Zhangjiang sluice is a large type(1)sluice project in Ganzhou,whose reinforcement project completed its final acceptance in 2021.For the reinforcement engineering design,considering the characteristics and existing problems of the sluice,the flood discharge capacity was significantly improved by optimizing the overall layout of the sluice hub and building the sluice spillway respectively on the left side of the south bank and the north bank.By optimizing the sluice scheduling mode,combined with the reinforcement of the original stilling pool and the construction of a new secondary stilling pool,new reinforced stone cage seascape and other measures,the problem of energy dissipation and anti-flushing was fundamentally solved.In view of the good results obtained after the reinforcement of the sluice,this paper reviews and summarizes the main design technical schemes for helping the design of similar projects.
