Therefore, in some cities with developed economy in China, the advanced municipal pipeline construction and maintenance methods abroad are used for reference, and comprehensive pipe gallery projects are built. The utility tunnel essence refers to municipal public facilities built underground in cities for laying urban engineering pipelines according to the unified planning, design, construction and maintenance principles.
In recent years, the construction of the comprehensive pipe rack in China enters a relatively high-speed period, however, the construction period of the cast-in-situ pipe rack which is adopted at present is long, the ground is seriously damaged, the noise and dust pollution are large, and the urban environment and the traffic are greatly influenced.
