Method for controlling pipeline settlement by enabling drainage pipeline to penetrate through soft soil layer
The invention relates to the technical field of pipeline settlement control construction, in particular to a method for controlling pipeline settlement when a drainage pipeline penetrates through a soft soil layer. The foundation soil body of the pipe bottom pipeline is reinforced through grouting, the pipeline is encapsulated by concrete with functional natural river sand or regenerated machine-made sand to reinforce the joint strength of the pipeline, meanwhile, flowing water at the joint of the pipeline is prevented from seeping outwards to erode the surrounding soil body, and the pipe top adopts a reinforced concrete top plate to disperse the traffic load borne by the pipeline. The quality problems of pipeline settlement caused by the fact that the pipeline penetrates through the soft soil layer, pipeline connector gap increase and even disjunction in the construction process and after construction are solved, and the problem that after the pipeline is put into operation, running water erodes and empties soil around the pipeline connector, and consequently the road surface sinks is solved. And the construction quality of the drainage pipeline and the service life and safety of the pipeline and the upper pavement in later operation are ensured.
本发明管道沉降控制施工技术领域，具体为一种排水管道穿越软土土层控制管道沉降的方法。本发明通过注浆加固管底管道基础土体，管道采用带有功能性天然河砂或再生机制砂的混凝土包封加固管道接口强度同时避免管道接口处流水外渗侵蚀周边土体，管顶采用钢筋混凝土顶板分散管道承受的行车荷载。通过上述解决了管道穿越软土土层引起的管道沉降、施工过程中和施工完成后管道接口缝隙增长甚至脱节等质量问题及管道投入运行后流水侵蚀掏空管道接口四周土体导致路面下沉的问题，确保排水管道的施工质量及后期运营中的管道及上部路面的使用寿命及安全。
