Abstract: In the bidding stage of a pumped storage power station, detailed analysis on key technologies of construction diversion was carried out. Reasonable construction diversion method, diversion buildings layout and construction scheme were proposed.The diversion scheme of cofferdam blocking the river combining with right tunnel was adopted. This diversion scheme was feasible, fast, economical and laid a solid foundation for reservoir construction.

Key words: construction diversion, diversion standard, cofferdam

摘要: 在某抽水蓄能电站招标设计阶段,对下水库施工导流关键技术问题进行了详细的论证分析,提出了合理经济的施工导流方式、导流建筑物布置及施工方法。施工导流采用上、下游全年围堰一次拦断河床、右岸导流隧洞过流的导流方式。该施工导流方案可满足大坝施工现场干地施工、连续快速施工及安全度汛要求,并为下水库大坝安全可靠、经济高效施工创造良好的条件。
