| description | The invention belongs to the field of petrochemical engineering and natural gas, and particularly relates to a protection device and method for an X80 buried pipeline to cross a seismic fracture zone. The protection device comprises an X80 buried pipeline, a protection pipeline, an end cone pipeline, a flange structure, a displacement sensor, an air pressure sensor, a pneumatic booster pump, an air storage tank, an air inlet pipe, an air outlet pipe, a signal transmission and receiving device, a microcontroller and an electromagnetic valve. When the X80 buried pipeline crosses the seismic fracture zone, the fault displacement can cause buckling deformation and even damage of the X80 buried pipeline. According to the device and the method, the area, influenced by fault displacement, of the X80 buried pipeline can be determined, the protection pipelines are additionally arranged in the area, the cavities between the protection pipelines are filled with nitrogen, and the gas pressure between the pipelines can be |
