摘要
随着城市的发展，地下管道承担着城市居民生活用水的供应和与日俱增的城市污水的排放。然而管道施工时，受市政交通的影响，城市地下管道工程明开槽的时代即将成为过去，非开挖施工技术势将越来越多的在城市地下管道工程中得到应用。但是，非开挖施工技术在城市地下管道施工中如何实施？本文将针对非开挖拉管施工技术进行整体的分析探讨。
Along with city development, the underground pipe is undertaking the urban residents＇ domestic water supply and increasing urban waste water emissions. When the plumbing engineering construction is carried out, it is influenced by municipal transportation. The era of open excavation for urban underground pipe project will be over soon, but the non-digging construction technology will surely be applied in the urban underground pipe project more and more. However, how can the non-digging construction be implemented for the urban underground pipeline construction？ The paper will generally analyze and discuss the non-digging pulling pipe construction technology.
