[0022] Furthermore, the depth of the groove 10 is half the thickness of the second protective plate 5, and the thickness of the block 11 is half the thickness of the first protective plate 4. Since the first protective plate 4 is fixed to the stable rock layer 3 by the anchor cable 8, the first protective plate 4 supports the second protective plate 5 through the block 11, making the overall laying more stable.

[0023] Furthermore, a plurality of planting grooves 12 are provided through the first protective plate 4 and the second protective plate 5 for planting vegetation, which can improve the overall stability of the slope and have the effect of beautifying the environment.

After the compensatory tensioning, 5 to 10 cm of steel strand 805 is reserved from the anchor 806, and the excess part is cut. Finally, cement paste is used to fill the gap between the anchor plate 804 and the first through hole 6, and the steel strand 805 extending out of one end of the anchor 806 is sealed with concrete of not less than 20 MPa.
