| 中文摘要:为满足某电厂供水需求，需在某水库进行岸边取水工程（含取水竖井、引水隧道、引水明渠3部分）施工。通过短段掘砌逆作工艺，井筒壁溶洞导水并将导出的水作为水源的一部分，实现了井筒干封底，顺利完成井筒施工；采用顶管技术+管顶注浆技术在破碎岩体、涌水量较大地层成功完成引水隧道施工；通过岩塞爆破成功实现引水隧道和水库的连接；通过船载冲击成槽技术，实现了引水明渠的施工。 |

| Abstract:To meet the water supply demand of a power plant, the water intake engineering construction (containing water intake shaft, draw water tunnel and open diversion channel) at a reservoir was needed. By means of the top-down method of excavation with lining alternated in short segments, guiding cavern water from shaft wall was derived as a part of the water source, and the shaft construction was completed with dry bottom-sealing. By pipe jacking and pipe top grouting technologies, draw water tunnel was accomplished in the strata with broken rocks and abundant water inflow; by the rock plug blasting, the connection of the tunnel and the reservoir was successfully realized; and by percussive trenching technology, open diversion channel was constructed. |
