Pipeline side settlement prevention system for soft soil foundation and construction method

Abstract

The invention discloses a pipeline side settlement prevention system for a soft soil foundation and a construction method. The pipeline side settlement prevention system for the soft soil foundation comprises a pipeline, a structure pool wall, a structure bottom plate, a concrete base plate and a sand foundation, one end of the pipeline penetrates through and is fixed on the structure pool wall, one end of the structure bottom plate extends out of the outer surface of the structure pool wall to form an overhanging scaffold, the concrete base plate is located under the pipeline, one end of theconcrete base plate is fixed to the overhanging scaffold, and the sand foundation is located above the concrete base plate. The concrete base plate has certain strength and rigidity, and one end of the concrete base plate is fixed to a structure, so that differential settlement of a soft soil foundation pipeline and the structure can be coordinated by means of the strength and rigidity of the concrete base plate, and the problems of flexural joint damage, pipeline tension fracture, water leakage and the like caused by differential settlement of the pipeline at the joint of the pipeline and thestructure are effectively solved.

Description

technical field [0001] The invention relates to a pipeline side settlement preventing system for soft ground and a construction method for preventing pipeline side settlement for soft ground. Background technique [0002] The structures of sewage treatment plants in soft soil foundation areas often use pile foundations with almost no settlement, while the pipelines connected to the structures generally use sand and gravel foundations. Due to the lack of backfilling or the settlement of the soft soil itself, the pipelines settle more, resulting in pipelines There is obvious uneven settlement between the structure and the structure. A lot of engineering experience shows that the connection between pipelines and structures is often prone to problems such as flex joint tearing, pipeline tearing and water leakage due to uneven settlement, which seriously affects the normal operation of the sewage treatment plant, and in severe cases leads to Sewage treatment plants shut down and...
