泥水平衡长距离顶管施工技术要点

Technical Measures of Long-distance Pipe-jacking Construction with Mud and Water Balance

结合沧州市迎宾大道污水管道工程,介绍了长距离泥水平衡顶管施工的技术要点,包括合理确定顶力的方法、注浆减阻措施、确保止水圈可靠工作的方法、测量纠偏措施等,从而为相关工程的施工提供借鉴。

Combining with the sewage Conduit engineering of Yingbin Avenue in Cangzhou City, the technical measures of long-distance pipe-jacking construction with mud and water balance are introduced. The technical measures include the reasonable determination of jacking force, reducing the jacking resistance by injecting slurry, ensuring the reliable work of sealing collars and correcting the error of survey, thereby, which provides a reference for the construction of relevant engineering.
