摘要
洪屏抽水蓄能电站每条引水洞共有2条竖井,上竖井高程差为277 m,下竖井为295 m,施工条件差,开挖过程中安全及质量控制难度大。从施工方案选择、竖井施工平面布置、施工工艺等几个方面,对洪屏抽水蓄能电站引水竖井开挖施工实施过程进行了介绍。防坠罐笼、防坠器、视频监控设备等现代科技的应用,保证了竖井开挖施工的安全。
Each diversion tunnel in Hongping Pumped-storage upper shaft and lower shaft are 277 m and 295 m respectively. Power Station consists of two shafts. The height differences of The safety and quality control in the process of shaft excavation are difficult as poor construction conditions. From the aspects of shaft construction scheme selection, construction layout and construction technology, the actual excavation of shafts are introduced. The application of anti-dropping cage, parachute system and video monitoring ensure the safety of shaft excavation.
