非开挖水平定向钻机拉管相关施工技术探讨

摘要

非开挖技术施工对减少和控制河道、堤防、道路等管线重复开挖，改善现场作业环境、加快施工速度、节约工程投资、加快水利发展具有重要意义。本文结合南水北调丰县沛县尾水资源化利用及导流工程———大沙河拉管工程，探讨非开挖水平定向钻施工技术及其应用前景。%Trenchless technology construction has important significance for reducing and controlling repeated excavation on river channel,embankment,road and other pipelines,improving site working environment,accelerating construction speed,saving project investment,and accelerating the development of water conservancy.In the paper,trenchless horizontal directional drill construction technology and its application prospect are discussed combining with South-to-North water diversion Fengxian County and Peixian County tail water resources utilization and diversion project—Dasha River Tubing Project.
