在大中城市建设中,特别是在城市建设之初,有必要对地下管道公共设施实行最佳设计和统一规划,使地下管道公共设施成为隧道式的永久性建筑,地下公共设施隧道含有给水管、污水管、电力、供热、路灯、信号、通信、光缆、电缆和煤气管道等,这些管线集中布置在隧道或管廊内,避免了管线扩容和维修时的开挖路面,因为管线悬空存放在隧道或管廊内,有效避免了路面不均匀下沉导致的挤压,并且方便了今后对管线的养护和维修,使之成为有关单位及部门共同使用、共同享有、有效利用和有利于城市环境发展建设的地下基础公共设施。
In large and medium-sized cities, especially at the beginning of urban construction, it is necessary to carry out the optimal design and unified planning of underground pipeline public facilities so that the public underground tunnels become permanent tunnel-type buildings. The underground public utility tunnels contain water supply pipes , Sewage pipes, electricity, heat supply, street lamps, signals, communications, optical cables, cables and gas pipelines. These pipelines are arranged in tunnels or pipe galleries in a centralized way, avoiding the excavation of pipelines during expansion and maintenance. In the tunnel or pipe gallery, effectively avoid the uneven subsidence caused by the road squeeze, and to facilitate the future maintenance and repair of the pipeline, making it the relevant units and departments to jointly use and enjoy, and effective use of and in favor of the city Environmental development and construction of underground infrastructure based public facilities.
