Slope Active Protection Network in galvanized steel wire rope + as the main material of the active protection network system with high toughness, high protection strength, high corrosion and rust, easy spreading and so on. Suitable slope collapse, weathering, Slough, slippery or slump class geological disaster prevention, Active Protection Network on hillslope morphology no special requirements, do not destroy and change the slope of the original topography and vegetation conditions, while back to artificial afforestation retain the necessary conditions. Model grid support rope stitch rope main protection Remarks GAR1 (ordinary simple type) DO / Φ8 / 300 (wire rope) Φ16 edge (or on the edge), wire rope anchor + Φ12 edge (or on the edge) support rope Φ8 envelope effect, limiting the range of motion of falling rock, partially inhibited the occurrence of collapse single wire rope, anchor length generally 2m-3m, pullout force is not less than 50kN GAR2 (common type) DO / Φ8 / 300 (wire rope) Φ16 rope anchor system + Φ16 lateral support rope + Φ16 (12) longitudinal support rope Φ8 slope reinforcement, inhibition of collapse and weathering, slip collapse occurred, limiting the range of motion of falling rock or a small number of local single-wire rope, opening the pit + tensioning anchor rod length generally 2m-3m, pullout force is not less than 50kN GPS1 (ordinary common type) DO / 8/300 + SO / 2.2 / 50 / 2.25 × 10.2 (wire rope + wire mesh grille) Φ16 edge (or on the edge) , wire rope anchor + Φ16 edge (or on the edge) support rope Φ8 with GAR1, there are small rockfall choice when double net (wire rope + wire grid), anchor length generally 2m-3m, pullout force is not less than 50kN ★ GPS2 (ordinary common type) DO / 8/300 + SO / 2.2 / 50 / 2.25 × 10.2 (wire rope + wire mesh grille) Φ16 system wire rope anchor + Φ16 lateral support rope + Φ16 (12) longitudinal support rope Φ8 with GAR2, when there is the choice of small rock or soil slope dangerous double net (wire rope + wire grid), anchor length generally 2m-3m, pullout force is not less than 50kN GER1 SO / 2.2 / 50 / 2.25 × 10.2 (steel wire mesh) Φ16 edge (or on the edge), on the edge of the wire rope anchor + Φ12 support rope, Φ12 lower edge of the support wire ropes ≥Φ2.2 seam contract GAR1, but falling stones body smaller and more demanding life Short chosen to guard the main shattered single wire rope, anchor length generally 2m-3m, pullout force is not less than 50kN GER2 SO / 2.2 / 50 / 2.25 × 10.2 (steel wire mesh) Φ16 system wire rope anchor + Φ12 lateral bracing wire ropes ≥Φ2.2 seam contract GPS2, but the risk is small and the rock body requires a shorter life when using single wire rope, anchor length generally 2m-3m, pullout force is not less than 50kN GTC- 65A TC / 65 (high strength steel Sige) prestressed steel bolt + orifice pit (need to choose based on the border with child support rope and wire rope anchor) Φ8 with GPS2, can meet up to 100 years longer corrosion life requirements, but it is only about strengthening the capacity of its 70% to 80%, is not suitable for volume greater than 1m3 chunk single solitary dangerous rock reinforcement of high-strength steel wire mesh grille GTC-65B TC / 65 (high strength steel Sige) Φ16 edge (or on the edge), wire rope anchor + Φ16 edge (or on the edge) support rope Φ8 with GAR1, can meet up to 100 years longer corrosion life requirements, but not suitable for volume greater than 1m3 single chunk of rockfall protection high-strength steel wire mesh grille, anchor length generally 2m-3m, pullout force is not less than 50kN
