市政大直径污水管道不断流施工方法研究和应用

Research and Application of Continuous Flow Construction Method for Municipal Large Diameter Sewage Pipeline

随着国内经济快速发展,城市建设日益繁荣,近几年,全国各大中型城市隧道工程建设如火如荼,因隧道施工将不可避免的对原有市政管线带来影响,管线问题已成为隧道施工中的难题之一。将管线拆除或改迁虽行之有效,但囿于客观条件,一些隧道仍不得不穿越管线进行施工。尤其对雨污水管线,因大多修建时间久,时有渗漏情况发生,因此如何保证隧道施工时雨污水管线及工作面安全,成为隧道施工中亟待解决的问题。

With the rapid development of domestic economy and the prosperity of urban construction,in recent years,the construction of tunnel projects in large and medium-sized cities across the country is in full swing.Because the tunnel construction will inevitably affect the original municipal pipelines,the pipeline problem has become one of the difficulties in tunnel construction.Although it is effective to dismantle or relocate pipelines,some tunnels still have to cross pipelines for construction due to objective conditions.Especially for the rainwater and sewage pipelines,since most of them have been built for a long time,leakage occurs from time to time.Therefore,how to ensure the safety of the rainwater and sewage pipelines and the working face during the tunnel construction has become an urgent problem to be solved in the tunnel construction.
