供热管道穿越岩层水平定向钻施工技术

Horizontal Directional Drilling Construction Technology for Heating Pipeline Crossing Rock Stratum

随着我国工程建设的发展,管道在敷设的过程中,经常遇到各种障碍物需要用非开挖施工方法进行穿越,其中,水平定向钻钻进技术是非开挖施工技术中的重要部分,主要用于穿越道路、河流、建筑物及一些不具备明挖的山体等障碍物,相比于顶管、隧道等施工方法,水平定向钻具有施工速度快、成本低等优点。水平定向钻技术已在供热管道敷设工程中广泛应用。

With the development of engineering construction in China, in the process of laying pipelines, various obstacles are often encountered and need to be traversed by trenchless construction methods. Among them, horizontal directional drilling technology is an important part of trenchless construction technology. It is mainly used for crossing roads, rivers, buildings and some obstacles such as mountains without open cut. Compared with construction methods such as pipe jacking and tunnels, horizontal directional drilling has the advantages of fast construction speed and low cost. Horizontal directional drilling technology has been widely used in heating pipeline laying projects.
