摘要
主要探究了夹岩水利枢纽工程织金管线织支2+658~4+158段穿越洪家渡库区尾水木空河蓄水淹没区段的安全高效施工技术。通过管道穿越段的地质调查、水文监测分析,确定河床穿越段的施工特点和难点,从快速、安全施工方面,着重研究了管道线路优化、河床地质勘察以及施工围堰等,总结了供水管道穿越库区河道施工技术,以期为其他类似工程提供借鉴。
The article mainly introduces the safe and efficient construction technology of the Zhijin 2+658~Zhijin 4+158 water-supply pipeline of Jayan Hydro-complex Project crossing the inundated Mukong River in tailwater ar⁃ea of Hongjiadu Reservoir.Through the geological investigation,hydrological monitoring and analysis of construc⁃tion characteristics and difficulties of the riverbed pipeline crossing and from the perspective of fast and safe con⁃struction,the pipeline route optimization,riverbed geological survey,construction cofferdam,construction tech⁃nology,etc.are focused,and the construction technology of water supply pipeline crossing the river channel in the reservoir area is summarized to provide reference for other similar projects.
