On both sides of the outer wall of the pressure plate 11, the assembly groove 18 is opened inside the transverse rib 13, the first anchor hole 15 is opened inside the transverse rib 13, the assembly 21 is installed on the inner wall of the assembly groove 18, the mounting protrusion 22 is fixedly connected to the outer wall of the assembly 21, the steel rope 23 is fixedly connected between the outer walls of a pair of mounting protrusions 22, the assembly anchor hole 24 is opened inside the assembly 21, the outer wall of the transverse rib 13 and the outer wall of the U-shaped groove 12 fit together, the assembly anchor hole 24 and the first anchor hole 15 are correspondingly set, and the longitudinal anchor rod 14 is installed on the inner wall of the first anchor hole 15 and the assembly anchor hole 24. The flexible connecting strip 2 is designed to facilitate the interaction between the fitting 21 inside the flexible connecting strip 2 and the assembly groove 18 inside the transverse rib 13, as well as the assembly anchor hole 24 on the fitting 21 and the first anchor hole 15 inside the transverse rib 13. This design allows for quick installation of the flexible connecting strip 2 on both sides of the same-level arc-shaped pressure plate 11 by simply inserting the longitudinal anchor rod 14. This achieves lateral linkage between the same-level arc-shaped pressure plates 11. The transverse ribs 13 on both sides of the arc-shaped pressure plate 11 and the U-shaped slots 12 on the lower side of the arc-shaped pressure plate 11 engage with each other, enabling overlapping and engaging relationships between upper and lower level arc-shaped pressure plates 11. Combined with the longitudinal anchor rod 14 that runs through the three levels of arc-shaped pressure plates 11, this achieves the series locking characteristics between multiple levels of arc-shaped pressure plates 11.

The fastening bolt 31 is threadedly installed on the outer wall of the threaded rod 32, and the lower end face of the fastening bolt 31 is in contact with the upper surface of the arc-shaped bearing plate 11. With this structure, the arc-shaped bearing plate 11 can be firmly fixed to the surface of the high slope by installing the fastening bolt 31.

[0034] The assembly rod 33 is vertically installed on the inner wall of the high slope and is made of cast concrete.

After the drilling is completed, the corresponding concrete pouring equipment pours concrete into the hole, and while the concrete is in a fluid state, the threaded rod 32 is inserted into the concrete in the hole until the concrete in the hole solidifies.

[0036] Step 1: Align the pair of mounting holes 34 on the lower arc-shaped bearing plate 11 with the threaded rod 32 fixed on the high slope, place it on the surface of the high slope, and finally fix the arc-shaped bearing plate 11 firmly on the surface of the high slope by threading the fastening bolt 31 onto the threaded rod 32.

[0037] Step 2: Align the U-shaped slot 12 on the lower side of the upper arc-shaped bearing plate 11 with the transverse ribs 13 on both sides of the lower arc-shaped bearing plate 11 and engage them. Then, by threading the fastening bolts 31 onto the threaded rods 32, the arc-shaped bearing plate 11 is firmly fixed to the surface of the high slope, thus completing the installation and fixing of the upper arc-shaped bearing plate 11.

Align the longitudinal anchor rod 14 with the first anchor hole 15 on the transverse rib 13 and insert it through the first anchor hole 15 on the upper transverse rib 13 and the third anchor hole 17 on the middle arc-shaped bearing plate 11 until it reaches the first anchor hole 15 on the lower transverse rib 13. Through the cooperation between the longitudinal anchor rod 14 and the assembly anchor hole 24 on the fitting 21, fix the fitting 21 in the inside of the assembly groove 18 and fix the flexible connecting strip 2 to the side of the support structure 1.

[0039] Step 4: Next, align the assembly holes 34 on the same layer of the arc-shaped bearing plate 11 with the threaded rods 32 on the high slope, and perform Step 1, Step 2 and Step 3 in sequence until the support structure 1 covers the entire slope surface of the high slope.
