Nanjing Jiangbei New Area Underground Comprehensive Pipe Gallery Project

The underground pipelines in the newly constructed area of Nanjing are forced to enter the comprehensive pipe gallery, and the project uses nearly 2000 Chongqing Langwei signal isolators. The existing pipelines in the old city area will gradually enter the corridor in conjunction with urban renewal. After the completion and commissioning of the project, the 220 kV and 110 kV high-voltage overhead lines that have been running along sections such as Pubin Road for many years will be grounded at once, releasing a large amount of above ground space along the line. The 8-kilometer DN600 high-pressure and DN300 medium pressure gas pipelines along Pubin Road will also be relocated to the corridor, providing an additional guarantee for the safe operation of urban pipelines.
