非开挖管线铺设技术是利用岩土钻掘手段,在地表不开槽的情况下铺设、修复和更换地下管线的一项施工新技术,它与传统的挖槽埋管方法相比,具有不破坏环境、不影响交通、施工安全性好等优点。 河北省地质勘探局立足中国国情,全部采用国产仪器、设备和工具,成功地开发了这项新技术。他们研制开发的非开挖导向孔 Non-excavation pipeline laying technology is a new construction technology that uses geotechnical drilling and excavation methods to lay, repair, and replace underground pipelines without surface trenching. Compared with traditional trenching methods, it has no Destruction of the environment, does not affect traffic, construction safety and other advantages. The Geological Exploration Bureau of Hebei Province has successfully developed this new technology based on China’s national conditions, all using domestically produced instruments, equipment and tools. The non-excavation pilot hole they developed
