Abstract
Embodiments of the present disclosure provide a frost-heave-resistant pile foundation support device including a pile foundation cylinder, a pile foundation cylinder top seat, a pile foundation cylinder base, and a frost heave penetration mechanism, wherein a top of the pile foundation cylinder is fixedly installed with the pile foundation cylinder top seat, and the pile foundation cylinder top seat is configured to connect to a target to be support; the pile foundation cylinder base is disposed at a bottom of the pile foundation cylinder, and a plurality of threaded drill rod assemblies are provided on the pile foundation cylinder; the frost heave penetration mechanism is fixedly installed on a cylindrical wall of the pile foundation cylinder. When soil undergoes frost heave action, a horizontal anchor rod of the frost heave penetration mechanism can penetrate laterally outward into the soil, so that the pile foundation cylinder is anchored to the surrounding soil, which serves as a frost-heave-resistant effect.
