Technical specification for urban integrated pipeline corridor engineering

　　On June 1, 2015, "Technical Specifications for Urban Integrated Pipeline Corridor Engineering" (GB50838-2015) was implemented, which greatly modified and improved the 2012 version of "Technical Specifications for Urban Integrated Pipeline Corridor Engineering", and played a positive role in promoting the construction of our comprehensive pipeline corridor. This version of the specification emphasizes that in principle all pipelines must enter the corridor. But also expanded the classification of the comprehensive pipe corridor, a new cable pipe corridor.

　　The underground integrated pipeline corridor system not only solves the problem of urban traffic congestion, but also greatly facilitates the maintenance and overhaul of municipal facilities such as power, communication, gas, water supply and drainage. In addition, the system also has a certain role in earthquake prevention and disaster reduction. For example, during the Great Kobe earthquake in 1995, a large number of houses collapsed and roads were destroyed in Kobe City, but most of the underground integrated corridors were intact, which greatly reduced the difficulty of post-earthquake relief and reconstruction work.

　　The Guiding Opinions of The General Office of the State Council on promoting the construction of Urban Underground Comprehensive Management Corridors (No. 61, 2015) were published on August 10, 2015. The goal is to build and put into operation a group of internationally advanced underground integrated pipe corridors by 2020, significantly improve the "road zipper" problem caused by repeated excavation of the ground, significantly improve the safety level of pipelines and the ability to prevent and resist disasters, gradually eliminate the spider web overhead lines in main streets, and significantly improve the urban ground landscape.
