Description

Technical Field

[0001] This invention belongs to the field of integrated utility tunnel and urban rail transit engineering technology, specifically relating to a connection structure between a utility tunnel and a subway. Background Technology

[0002] Integrated utility tunnels, as a modern and intensive urban infrastructure, centrally house two or more municipal pipelines in one underground space, while also providing ancillary systems such as maintenance, hoisting, ventilation, fire protection, drainage, lighting, and monitoring. Compared with traditional laying methods, they have many advantages, such as eliminating urban zip lines, ensuring the safe operation of urban "lifelines," effectively utilizing underground space, improving the urban construction environment, and centralized information management of municipal pipelines. They represent the trend in the development of municipal pipeline laying.

[0003] However, the underground cross-sectional area of ​​integrated utility tunnels and the surface maintenance and ventilation openings are relatively large. Given the scarcity of land resources, the tightness of construction land, and the difficulty of relocating utility lines in the central urban area, it is very difficult to build and implement a structure of this size.

[0004] Urban rail transit projects (subways) also require ground land for ancillary facilities (ventilation shafts, entrances and exits, etc.).

[0005] Currently, the domestic engineering situation is that integrated utility tunnels and urban rail transit projects (subways) are planned and constructed independently without being considered together. Summary of the Invention
