The utility model relates to the technical field of
road engineering, and particularly discloses a cooling ecological side slope
pile net structure roadbed which comprises a heat reflection
road surface, a cooling
vegetation side slope, a roadbed filling layer, a mattress layer, a
pile net structure and a U-shaped drainage structure. The heat reflection
road surface is laid on a
subgrade filling layer, cooling
vegetation side slopes are arranged on the two sides of the
subgrade filling layer, geogrids are additionally arranged in the
subgrade filling layer to enhance the stability of the subgrade filling layer and prevent
cracking, a mattress layer is arranged below the subgrade filling layer, and a
pile net structure is arranged below the mattress layer. A threaded structure is arranged at the lower end of the pile net structure pile foundation, so that the pile net can be inserted below the frozen soil upper limit of a frozen soil layer, and U-shaped drainage structures are arranged outside the two sides of the cooling
vegetation slope corner. The heat reflection
road surface can improve the proportion of reflected solar
radiation and prevent heat from being transmitted to the frozen soil layer, vegetation is planted on the two sides of the roadbed, and ecological cooling is achieved. Meanwhile, U-shaped drainage structures are arranged on the two sides of the roadbed, and hydrothermal
erosion is prevented.
