摘　　要：长距离输水管道施工面临地形复杂、水流条件繁杂、管道长、施工周期长等问题,施工技术有其特殊性,对管网建设的要求也越来越高,而跨宽深河道输水管道施工情况更为复杂。结合某水利枢纽输水管线工程跨宽深河道段大口径输水管道施工案例,对施工过程中采用的主要方法进行简要阐述,为类似工程提供参考依据。The construction of long-distance water diversion pipeline is faced with such problems as complex terrain,complicated flow conditions,long pipeline and long construction period.The construction technology has its particularity,and the requirements for pipe network construction are becoming higher and higher.The construction of water diversion pipeline across wide and deep rivers is more complex.This paper briefly describes the main methods used in the construction process in combination with the construction case of large-diameter water diversion pipeline across wide and deep rivers of a water project,to provide reference for similar projects.
