[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 A highway roadbed protection structure shown includes multiple protection units, which are laid in sequence along the length of the highway to achieve complete protection of the highway roadbed. Each protection unit includes two left-right symmetrical protection frames 1, and the protection unit also includes an upper connecting beam 2 and a lower connecting beam 3. The upper connecting beam 2 and the lower connecting beam 3 are fixedly connected between the two protection frames 1 to form the outline frame of the protection unit.

[0018] like Figure 2 As shown, the protective frame 1 includes a straight upper frame 4 and a straight lower frame 5, and the upper frame 4 and the lower frame 5 are connected by an inclined middle frame 6; the protective frame 1 is a prefabricated reinforced concrete component, and the height of the protective frame 1 is the same as the height from the roadbed to the road surface, the upper frame 4 is fixed to the road surface, and the lower frame 5 is fixed to the bottom of the roadbed.

[0019] A plurality of plug-in boards 7 extend horizontally from the inner side of the protective frame 1. The plug-in boards 7 are buried in the roadbed, thereby enhancing the connection strength between the protective frame 1 and the roadbed and preventing the protective frame 1 from slipping off the roadbed slope.

[0020] The upper frame 4 is provided with a first step groove 8 corresponding to the upper connecting beam 2, and the upper connecting beam 2 is embedded in the first step groove 8 and fixed by bolts. The lower frame 5 is provided with a second step groove 9 corresponding to the lower connecting beam 3, and the lower connecting beam 3 is embedded in the second step groove 9 and fixed by bolts. The step groove is used to install the connecting beam so that the installed connecting beam can be flush with the frame. Figure 3 shown.

[0021] The upper connecting beam 2, the lower connecting beam 3 and the two middle frames 6 form a slope surface, and a mesh layer 10 is fixedly connected to the slope surface by bolts. The mesh layer 10 is a protective net, which covers the roadbed soil to prevent soil landslide. A fiberglass asphalt shingle layer 11 is fixed on the outside of the mesh layer 10. The fiberglass asphalt shingle covering the mesh layer 10 can block rainwater and prevent rainwater from damaging the roadbed soil. On top of this, a wear-resistant and pressure-resistant protective layer can be set on the outside of the fiberglass asphalt shingle layer 11.
