the buffer layer is provided with a one-way permeation hole and an overflow hole, and the opening area of the one-way permeation hole is larger than that of the overflow hole; the one-way permeation hole is communicated with the water storage layer;

the seepage-proofing anti-freezing ecological slope protection structure also comprises a pipeline and a water diversion member, wherein one end of the pipeline is communicated with the overflow hole, and the other end of the pipeline is positioned in the soil layer; the water diversion piece penetrates through the pipeline and is simultaneously connected with the water storage layer and the soil layer, and the water diversion piece is used for leading water in the water storage layer into the soil layer.

7. The ecological slope protection structure of prevention of seepage frostbite of claim 6, characterized in that:

the water diversion piece is arranged as a cotton thread or a capillary tube.

8. The ecological slope protection structure of prevention of seepage frostbite of claim 1, characterized in that:

the protective structure layer further comprises an adjusting layer, and the adjusting layer is arranged between the flexible protection pad and the impermeable layer and used for filling a gap between the flexible protection pad layer and the impermeable layer.

9. The ecological slope protection structure of prevention of seepage frostbite of claim 8, characterized in that:

the adjusting layer comprises a second steel mesh bag and second stones arranged in the second steel mesh bag, and the grain size of the second stones is smaller than that of the first stones.

10. The construction method of the anti-seepage anti-freezing ecological slope protection structure is characterized by comprising the following steps:

finishing the side slope;

paving a flexible protection pad on the side slope;

arranging a reinforced concrete layer with a plurality of accommodating grids on the flexible protection pad, and sequentially arranging an impermeable layer, a water storage layer and a buffer layer in each accommodating grid in the height direction of the side slope, wherein the impermeable layer is connected with the flexible protection pad;

and paving a soil layer on the buffer layer and the reinforced concrete layer, and planting plants in the soil layer.
