[0026] During construction, a reserved hole is first drilled on the slope body 1, and then the horizontal plate 2 is installed. After the horizontal plate 2 is installed, the vertical plate 3 is embedded in the groove 10, and at the same time, the block 15 on the vertical plate 3 is installed together with the corresponding groove 11 on the horizontal plate 2, which plays a positioning role, facilitates the rapid splicing of the horizontal plate 2 and the vertical plate 3, saves time and labor, and speeds up the construction speed; then, an anchor rod is inserted into the connection between the horizontal plate 2 and the vertical plate 3 for reinforcement, and the anchor rod passes through the unstable layer 7 and is inserted into the slope body 1 to improve stability. The utility model has a simple structure, is easy to install, has high construction efficiency, and has good stability, and can play a good reinforcement role on soft rock slopes.

[0027] In a further optimized solution, a first circular hole 12 is provided in the groove 10, and a plurality of second circular holes 14 are provided at equal intervals on the vertical plate 3. The plurality of first circular holes 12 are arranged in one-to-one correspondence with the plurality of second circular holes 14, and the anchor rods sequentially pass through the second circular holes 14 and the first circular holes 12. When installing the horizontal plate 2, the first circular hole 12 is aligned with the reserved hole to facilitate the subsequent installation of the anchor rod, and after the clamping block 15 is inserted into the clamping groove 11, the second circular hole 14 is aligned with the first circular hole 12 at this time, and no calibration and positioning are required again, saving time.

[0028] Further optimized solution, the anchor rod includes a sleeve 8, which passes through the second circular hole 14 and the first circular hole 12 in sequence and is inserted into the slope body 1, and the inner thread of the sleeve 8 is connected with the screw rod 5, and the top of the screw rod 5 is located above the vertical plate 3. The sleeve 8 passes through the first circular hole 12 and the second circular hole 14 and extends into the reserved hole, and the nut on the top of the screw rod 5 fits with the vertical plate 3 to prevent rainwater from flowing into the reserved hole along the gap.
