在流砂土层中的管道投入使用后,管道自身及周边的土层处于一种平衡的状态。但进行管道迁改会给周边的土体带来扰动,破坏原有的平衡状态。为保证原有设施的正常运行及工程项目的实施,需综合考虑多方面因素。结合无锡市南泉古镇现状污水管道迁改工程,介绍了流砂土层中管道迁改的技术问题与处理措施,供类似工程参考。 After the pipe in the quicksand layer is put into use, the pipe itself and the surrounding soil are in a state of balance. However, the relocation of pipelines will bring disturbances to the surrounding soil and destroy the original balance. In order to ensure the normal operation of the original facilities and the implementation of the project, we must consider various factors. Combined with the status quo of sewage pipe relocation project in Nanquan Town of Wuxi City, the technical problems and handling measures of pipe relocation in flowing sand soil are introduced for reference of similar projects.
