小口径顶管施工在市政污水管道项目中的应用研究

APPLICATION RESEARCH OF SMALL DIAMETER PIPE JACKING CONSTRUCTION IN MUNICIPAL SEWAGE PIPELINE PROJECT

在当前市政污水项目中,顶管施工作为一项相对成熟的施工技术已经很常见。面对实践中各种口径和材质的污水管道施工,小口径管道顶管施工在特点条件下发挥出了具有优势的一面,从顶管施工理论出发,以污水管道实践案例论述了小口径顶管施工的注意要点,为类似项目施工提供一定参考经验。

In the current municipal sewage projects,pipe jacking construction has become very common as a relatively mature construction technology.Faced with the construction of sewage pipes of various diameters and materials in practice,the pipe jacking construction of small-diameter pipes has played an advantageous side under the characteristic conditions.This paper starts from the theory of pipe jacking construction and discusses the smalldiameter pipe jacking with practical cases of sewage pipes.The key points for attention in pipe construction will provide some reference experience for similar project construction.
