Frost heaving resistant photovoltaic support foundation

The invention provides an anti-frost heaving photovoltaic support foundation, and belongs to the technical field of support foundations, the anti-frost heaving photovoltaic support foundation comprises a hole located in a soil layer, and a supporting section, a prefabricated pipe pile and an anti-frost heaving layer are arranged in the hole; the supporting section is arranged on the bottom layer of the hole and laid on the lower layer of the prefabricated pipe pile. The prefabricated pipe pile and the hole are coaxially arranged, and the upper surface of the prefabricated pipe pile is higher than the top of the hole and extends to the position above the soil layer; the prefabricated pipe pile is of a cylindrical structure; the anti-frost heaving layer is formed by solidifying an anti-frost heaving material, and the anti-frost heaving material is filled in the prefabricated pipe pile and a hole gap between the prefabricated pipe pile and the soil layer; reinforcing ribs are further arranged on the outer side w
