工程建设中地下管道施工通常采用明挖和非开挖进行，明挖施工在城市基础设施建设中通常受场地、交通、环境保护等因素制约多数无法进行；近年来，非开挖敷设管道技术得到广泛使用。由于在不需要开挖面层的情况下，便能穿越地面建筑物，或者地下管线及公路、铁路、河道。施工时对城区的交通、噪音、粉尘的危害和影响大大降低。为了达到最小的破坏和最大程度保护环境的目的，在城市电网改造中采用非开挖技术施工势在必行。

Underground pipeline construction usually adopts open cutting and trenchless construction. Open cutting is usually not available in municipal infrastructure construction due to limitation in site, transportation, environmental protection and other factors. In recent years, the trenchless pipe laying technology is widely used. It can pass through the ground buildings or underground pipeline, highway, railway, waterway without surface excavation. The influence on traffic, noise and dust can be reduced a lot. In order reduce the destruction to the minimum and maximize the protection of the environment, it is an imperative choice of using trenchless technology in the reform of the urban power grid construction.
