立洲水电站导流隧洞下闸预案浅析

Diversion Tunnel Gate Closing Plan at Hydropower Station

导流隧洞作为水利水电工程建设过程中的一项临时建筑工程,在工程挡水、取水口建筑物具备运行条件后一般均需进行永久封堵封闭。而导流隧洞封堵工作的前期准备及封堵的质量、进度及安全均会对后续工程及水利水电工程的按时及安全运行带来直接影响。浅析了导流隧洞封堵前的施工准备工作及施工中的注意事项,可为类似工程提供参考。

During construction of water resources and hydropower projects,diversion tunnels are temporary construction works and often are permanently plugged and closed after retaining works and intake works are ready for operations.However,early preparations for diversion tunnel plugging,plugging quality,progress and safety will directly influence safe operations of successive projects and water resources and hydropower projects.In this paper,construction preparations before diversion tunnel closed and cautions in construction are analyzed,providing references for similar projects.
