顶管技术能有效纠正管子在土层延神中出现的偏差,对于大中型管道非开挖铺设具有广泛的适用性。该技术的优点包括不破坏环境和地面建筑物,不开挖地面,不影响管道的段差变形,具备高效、经济、安全、保护环境等综合功能[1]。近年来随着我国人口密集、交通繁忙、地面建筑物增多和地下管线复杂,顶管技术在给排水管道施工中得到广泛应用,其经济效益和社会效益有目共睹。
Pipe jacking technology can effectively correct the deviation of pipe in the soil extension, which has a wide range of applicability for non-excavation of large and medium-sized pipelines. The advantages of this technology include not damaging the environment and the ground buildings, not digging the ground, not affecting the pipe section deformation, and having the comprehensive functions of high efficiency, economy, safety and environment protection [1]. In recent years, as China's densely populated, heavy traffic, increased ground buildings and complex underground pipelines, pipe jacking technology has been widely used in the construction of water supply and drainage pipelines, and its economic and social benefits are obvious to all.
