Supporting structure for protecting stability of pile foundation in soil slope engineering

The utility model discloses a supporting structure for protecting a pile foundation to be stable in soil slope engineering, which is characterized by comprising a plurality of strip-shaped fitting-slope concrete retaining walls which are uniformly arranged at intervals, and columns are arranged on a slope between the adjacent strip-shaped fitting-slope concrete retaining walls. A plurality of pre-stressed anchor rods are arranged on each strip-shaped fitting-slope concrete retaining wall at intervals in the height direction of the strip-shaped fitting-slope concrete retaining wall, net hanging steel bars are arranged on the surface of the side slope between the adjacent strip-shaped fitting-slope concrete retaining walls, concrete is sprayed on the surfaces of the net hanging steel bars, and non-pre-stressed anchor rods are further evenly arranged on the surface of the side slope between the adjacent strip-shaped fitting-slope concrete retaining walls. After supporting is completed, when the column starts to
