定向钻施工技术在南水北调配套工程中的应用

Application of Directional Drilling Construction Technology in South-to-North Water Transfer Project

定向钻敷管技术是一种现代非开挖敷设管道施工新技术。穿越南水北调总干渠采用定向钻施工,有效解决了不具备传统开挖埋管施工条件,不影响南水北调总干渠通水、不污染环境等问题,重点介绍了定向钻施工程序、定向钻施工、尾工处理等阶段的施工技术和质量控制要点。

Directional drilling pipe technology is a new construction technology of modem trenchless pipelines.Through the construction of the main channel of the South-to-North Water Diversion Project, the directional drilling construction is not solved.The construction conditions of the excavation pipe are not effectively affected, and the main channel of the South-to-North Water Diversion Project is not affected. The article mainly introduces the directional drilling construction procedure, processing and other stages of the construction technology and quality control points.
