- Abstract:
- The relocation of the municipal pipeline is a critical factor in subway construction. Enhancing the design efficiency and technical proficiency of pipeline relocation is a significant concern in subway design. Regarding the pipeline relocation for metro line 6 in Chengdu, a phased relocation approach for station construction was determined, and a standardized methodology for improving the design efficiency was established. Regarding the relocation of special high-risk pipelines, various innovative solutions were developed and implemented based on specific conditions. These included the segmented movement plan of an operating high-voltage power tunnel, the scheme of large-section sewage channel and the Jinjiang River embankment sharing the structure, and the scheme of in-situ protection of large-diameter gas pipelines during the half-cover excavation method adopted by the subway station. The design scheme facilitated the efficient advancement of subway construction. Therefore, it can serve as a valuable reference for similar projects.
