Salinized soil roadbed slope heat preservation and reinforcement structure under freeze-thaw cycle

The invention discloses a freeze-thaw cycle salinized soil roadbed slope heat preservation and reinforcement structure which comprises a pavement, a roadbed and a slope body, the pavement is laid on the upper portion of the roadbed, the slope body is arranged on the outer side of the roadbed, a heat preservation layer is laid on the upper portion of the outer side slope of the slope body, an anti-seepage layer is laid on the upper portion of the heat preservation layer, and an anti-erosion concrete layer is poured on the upper portion of the anti-seepage layer. A solar cell panel is erected on the upper portion of the anti-erosion concrete layer, heating anchor rods are arranged on the slope top, the slope toe and the slope face perpendicular to the slope body, and the heating anchor rods penetrate through the heat preservation layer, the impermeable layer and the anti-erosion concrete layer. According to the heat preservation structure, through the arrangement of the heat preservation layer, the anti-seepage
