The limiting support plate 9 is fixedly connected to the other end of the top of the support bottom plate 6.
[0024] During installation, the edge of the roadbed near the high slope is leveled and compacted, and then the support bases 2 are laid at equal intervals. The support bases 2 are reinforced to the edge of the roadbed by anchor rods 5. The support plates 3 are installed between two adjacent support bases 2 so that the support plates 3 are inserted into the insertion slots 10. Finally, the inclined support beams 4 are installed to reinforce the support plates 3 and improve the stability of the support plates 3.
