非开挖管道安装技术在市政管道维护中的应用

The Application of Trenchless Pipeline Installation Technology in the Maintenance of Municipal Pipelines

随着城市的快速发展,大量的市政排水管道需改建和扩建,由于传统开挖法的种种弊端,各种非开挖铺设管道的技术应运而生,而定向钻机拖管施工法就是一种比较有效的方法。这种非开挖技术具有工程造价低、对周边环境影响小、不需考虑降水措施等优点,在未来的城市管网改造中有着广阔的前景,值得我们去研究、开发。

Along with the rapid development of the cities,a lot of municipal drainage pipelines need rebuilding and expansion.Because of various disadvantages of traditional excavation method,different trenchless pipelines laying technologies arise at the historic moment,and directional drilling machine pipeline hauling method,which is a kind of effective method,possesses some advantages such as lower construction cost,less environmental impact,and no-consideration about rainfall measures,etc.This trenchless technology has a broad prospect in future urban pipeline transformation and is worthy of studying and exploring.
