The invention discloses a protection method for underground flexible pipelines. The protection method comprises the following steps that S1, the distribution condition of the underground flexible pipelines in a construction range is determined; s2, in the process of excavating the construction pit, protective excavation is conducted on the underground flexible pipeline; s3, a suspension protection frame is erected above the construction pit, and suspension protection is sequentially carried out in a segmented mode through the suspension protection frame according to the exposure condition of the underground flexible pipeline; and S4, settlement monitoring is conducted on the periphery of the underground flexible pipeline. The hanging protection for the underground flexible pipeline does not occupy too much construction space, so that the normal development of construction operation is not influenced; the suspension distance can be adjusted according to the pipe network property, the material and the old and new aging degree of the underground flexible pipeline, and targeted protection is carried out; the protection effect is guaranteed, material consumption is reduced, the construction cost is reduced, settlement around the pipeline is monitored, and the acting force of soil on the line pipe can be effectively detected so as to control the deformation degree of the pipeline.

    本发明公开了一种针对地下柔性管道的保护方法,包括以下步骤:步骤S1:确定施工范围内地下柔性管道的分布情况;步骤S2:在挖掘施工坑的过程中,对地下柔性管道进行保护性开挖;步骤S3:在施工坑上方架设悬吊防护架,通过悬吊防护架根据地下柔性管道暴露的情况,依次分段进行悬吊防护;步骤S4:对地下柔性管道周边进行沉降检监测。本发明提供的针对地下柔性管道的悬挂防护不会过多占据施工空间,进而影响施工作业的正常开展;可针对地下柔性管道的管网性质、材质及新旧老化程度,调整悬吊间距,针对性的进行保护;保证保护效果,且减少材料使用,降低施工成本,对管道周边的沉降监测,能够有效的检测土壤对线管的作用力,以控制管道变形程度。
