Study on the Impact of Subway Construction on Natural Gas Pipelines and Countermeasures
With the continuous development of first-tier and second-tier cities,subways have become one of the main transportation methods in cities.More and more cities are building subways.The impact of subway construction on the operation of underground natural gas pipelines has become one of the important safety issues faced by urban gas enterprises.From the perspective of urban gas enterprises,the impact of subway construction on natural gas steel pipelines is analyzed in three aspects:land subsidence caused by construction and even third-party damage,vibration caused by train operation and stray current.Combined with actual cases,requirements are put forward from the aspects of pipe selection,adjacent spacing requirements,steel pipe anti-corrosion system,land subsidence monitoring,etc.At the same time,corresponding countermeasures are also proposed for the construction supervision of subway construction,gas pipeline relocation and other operational aspects.
