- Abstract:
- The elevation conflict of underground pipelines is a common problem in the construction of urban stormwater and sewage diversion network. Taking a pipe jacking project in Shenzhen as an example, the paper analyzes the solution to pipeline conflicts and introduces the key points of top-down construction in the conflict section by wall protection wells, hydraulic rope saw and water cutting technology to connect high-level sewage pipes with new pipelines, and abolish pipeline plugging, thus realizing the relocation of sewage waterways and completing the construction of new pipelines crossing high-level sewer, which not only shortens the construction period while ensuring the safety, but also greatly reduces the project cost.
