超长距离曲线顶管跟进管轴线控制技术

Axis Control Technology for Follow-up Tube in Super Long-Distance Curved Pipe-Jacking

随着曲线顶管在地下管线工程中使用日益频繁,针对轴线控制的研究也越来越多,但多集中于工具管处。结合上海市污水治理白龙港片区南线东段工程中的超长距离曲线混凝土顶管施工,重点对后续跟进管节对土体的影响以及控制技术进行了阐述,为以后更为复杂的顶管积累了经验。

With the frequent use of curved pipe-jacking in the underground pipeline project, more researches on axis control appear, but many of them focus on the tools tube. Combined with a super long-distance curved concrete pipe-jacking construction in the wastewater treatment project in the south east part of Shanghai Bailong port area, the paper mainly introduced the influence of the follow-up tubes on the surrounding soil mass and the corresponding control technology so as to accumulate experience for more complicated pipe-jacking project in the future.
