[0015] Steps:
[0016] 1) Slope cleaning: remove debris on the slope, including pumice and floating soil, and level the slope;
[0017] 2) Anchor construction: mark the position of the anchor and carry out drilling operations. The diameter of the anchor hole is 32mm, the depth of the anchor hole is 400~600mm, the distance between the anchor holes is 1m × 1m, the diameter of the installed anchor is 12mm, and the length of the anchor is 450~550mm. Reserve the anchor rod length 5~7cm, bend the top of the anchor rod, and pour anchoring agent to fix it;
[0018] 3) Hanging net: Lay high-strength reinforced net 1 on the slope in step 2) and fix it on the reserved anchor rod on the slope. The high-strength reinforced net 1 is PVC-coated steel wire mesh, mesh size: 60*80mm , tensile strength ≥ 380Mpa;
[0019] 4) Lay plant rolls: lay plant rolls on the surface in step 3), and fix them on the reserved anchors on the slope; the plant rolls are sold and provided by Sichuan Woeryi E...
