重庆某抽水蓄能电站地下洞室群施工组织设计

Construction organization design of underground cavern group of a pumped storage power station in Chongqing

本文针对重庆某抽水蓄能电站地下洞室群施工,通过对施工涉及的供风、供水、供电进行研究计算,确定供风、供水、供电高峰强度,提出了地下洞室群施工通道布置、施工排水、开挖支护、混凝土浇筑、机电设备及金属结构安装等措施方案,可为其他抽蓄工程地下洞室群施工组织设计提供借鉴。

Aiming at the construction of underground cavern group of a pumped storage power station in Chongqing,this paper determined the peak intensity of wind supply,water supply and power supply by studying and calculating the air supply,water supply and power supply involved in the construction,and proposed measures such as the construction channel layout,construction drain⁃age,excavation and support,concrete pouring,mechanical and electrical equipment and metal structure installation of underground cavern group.It can provide reference for the construction organization design of underground cavern group in other pumping and storage projects.
