Example Embodiment
[0015] Example 1:
[0016] An anti-frost heave pile, which is composed of a prefabricated pile. The upper pile circumference of the prefabricated pile is provided with an anti-frost heave ring-shaped layer, and the anti-frost heave ring layer is composed of an anti-frost heave material.
Example Embodiment
[0017] Example 2:
[0018] According to the anti-frost heave pile described in embodiment 1, the pile body of the prefabricated pile is coated with asphalt or covered with linoleum, the anti-frost heave layer is backfilled sand, and the top of the anti-frost heave layer has a layer of waterproof cohesive soil. The precast piles mentioned are concrete precast piles or steel piles.
Example Embodiment
[0019] Example 3:
[0020] The above-mentioned construction method of anti-freeze heave piles, after leveling the working surface, use a drill to drill the anti-freeze hole 1, and then implant the precast pile 2 in the anti-freeze hole. The depth of the anti-freeze hole is greater than the depth of the frozen soil layer. The remaining space is filled.
