结合正井法施工的水电站调压井和竖井合并布置设计

Combined Arrangement Design of Surge Tank and Shaft for Hydropower Project with Down-Excavating Construction

德尔西水电站通过调整、优化设计方案,将调压井和压力管道竖井合并布置,采用快速正井法施工工艺进行竖井开挖和支护,采用滑模工艺施工衬砌混凝土,有效缩短了压力管道的工期,施工过程顺利,达到了预期目的,取得了良好的工程效益,是一次成功的探索和实践。

By adjusting and optimizing the design plan,DELSITANISAGUA Hydropower Project has merged the surge tank and the vertical shaft.The Down-Excavating construction method is used for the vertical shaft excavation and support.The sliding lining process is used to construct the lining concrete,which significantly cuts down the construction period of the pressure piping.The construction which achieved the expected purpose and favorable engineering benefits was a successful practice and exploration.
