Abstract:Taking the reconstruction design of the municipal pipeline in Shanbanqiao Road of Chengdu as an example, based on the engineering background of Shanbanqiao Road (Ring II ~ Middle Ring) in Chengdu Park Urban Street Integration Construction Pilot Project, the key points in the reconstruction design of the traditional municipal pipelines and the municipal pipelines under the park urban street integration concept are expounded. The application practice of park urban street integration design concept in this project is introduced. The pipeline status and demands of the reconstruction project are analyzed, and its boundary conditions of pipeline construction are analyzed. The innovative design scheme of utility tunnel for comprehensively laying pipelines used in the reconstruction of municipal pipelines is introduced in detail.
