正反井开挖施工技术在梅蓄电站下库闸门井上的应用

Application of Excavation Construction Technology of Positive and Reverse Wells in Lower Reservoir Gate shaft of Meicun Pumped Storage Power Station

闸门井作为抽水蓄能电站项目上的关键,施工进度直接影响蓄水发电时间。利用正反井施工技术进行闸门井的开挖,具有施工进度快、安全风险小、节约成本的优势,为电站按期蓄水发电提供条件,给类似闸门井开挖施工提供参考。

As the key of pumped storage power station project,the construction progress of gate shaft directly affects the time of water storage and power generation.It has the advantages of fast construction progress,low safety risk and cost saving to excavate the gate shaft by using the construction technology of positive and negative wells,which provides conditions for the power station to store water and generate electricity on schedule,and provides reference for similar gate shaft excavation construction.
