Abstract:Taking the Guangzhou International Innovation Town Launching Area Jinguangxi Avenue Utility Tunnel Project as an example, the aim is to explore the intensive and intelligent urban utility tunnel planning and design methods, and the key is to address the problems such as repeated road excavation, chaotic management and difficult maintenance caused by the traditional underground pipeline laying methods. The focus is on the study and analysis of cross-sectional selection and node design of utility tunnel. In view of the characteristics of the pipelines entering the utility tunnel such as DN1200 water supply pipes, 10 kV power 24-48 circuits, 110 kV power 3 circuits and 16-hole communication pipes, a reasonable utility tunnel design scheme is proposed, providing the technical references for similar projects. At the same time, the application of urban underground space resources is optimized, which is of great significance for improving the efficiency of urban underground space utilization, ensuring the safety of urban operations and enhancing the effectiveness of pipeline management.
