Abstract: Embodiments provide anti-frost heaving supports and methods for crude oil pipeline crossing permafrost region. The anti-frost heaving support includes a support frame. An arc-shaped frame is installed on a top of the support frame. Two sets of adjusting devices are disposed on the arc-shaped frame, each set of the adjusting devices includes a pushing device fixedly installed on the arc-shaped frame. In the anti-frost heaving support, a piston plate compresses air inside the sealing frame so that a compressional force of an elastic plate and a stressed plate on the pipeline increases. When the compressional force increases, the elastic plate deforms to make a moving rod to move towards to an interior of the sealing frame. When moving on a tilted surface of a tilting plate, the moving rod pushes the tilting plate to move. The tilting plate pushes the sealing plate to be opened to release the air inside the sealing frame, thereby reducing the compressive force exerted by the stressed plate on the pipeline.
