Underground Tunnel
The comprehensive pipe tunnel refers to an urban underground tunnel structure that accommodates various public pipelines in the city and leaves a passage for maintenance personnel. The common pipeline is a tunnel underground in a city that gathers together various pipelines such as municipal, power, communication, gas, water supply and drainage that were originally buried separately, so as to facilitate the implementation of unified planning, design, construction and management of these pipelines. It is suitable for important road sections with large traffic flow and many underground pipelines in the city.
