顶管施工技术在市政排水工程中的应用

摘要

In the municipal drainage projects, the technique of pipe jacking which is not largely excavated and is effective in reducing the impact to the nearby buildings, roads and pipe networks is widely used at present. In connection with the successful application of pipe jacking in rebuilding the northern branch sewer of Hongxing Southern Road in Chengdu, this paper discusses the technical measures and construction technology of pipe jacking construction, which will provide reference for the similar projects.%在市政排水工程中，非大开挖的顶管施工技术能够有效地降低对附近建筑筑物和道路、管网的影响，目前被广泛应用。结合成都红星路南延线改造北支渠排水工程施工中成功应用顶管施工技术的经验，简要论述顶管施工采取的技术措施和施工工艺，对于类似工程具有一定的借鉴意义。
