Active Rock Protection system

SPIDER slope stabilization system (high tensile steel wire netting) SPIDER slope stabilization system is a new form of active protection with high-strength steel stranded spiral mesh as the main body. For the reinforcement of high and steep rock slopes, the reinforcement of boulders and loose dangerous rocks. SPIDER slope stabilization system is a high-quality protection product. Main components: SPIDER high-strength steel strand spiral mesh, prestressed steel anchor rod, special anchor pad Fixing method: prestressed steel anchor rod, special anchor plate fastening Carrying capacity: better than all current flexible slope stabilization systems Design method: design system based on RUVOLUM theory Scope of application: overall stabilization and reinforcement of soil slopes and rock slopes, various types of boulder and dangerous rock reinforcement, and deep anchoring measures for slip control Breaking force: 195~220 kN/m Mesh shape: rhombus The noose net is woven from high-strength anticorrosive steel wire, the diameter of the inscribed circle of the diamond-shaped mesh is 250mm/130mm, and the standard size of the mesh is 10x3.5m; Anchor rod: generally use Φ25/28/32 ordinary threaded steel anchor rod with machined threads at one end (exposed section), or Φ25 fine-rolled threaded steel rod (such as GEWI anchor rod), and hot-dip galvanizing and other anti-corrosion treatments as required. Self-drilling hollow bolts can be used when holes are difficult; Anchor plate: diamond-shaped steel plate, four corners with buckle claws, size not less than 320x180mm,  its structure can be changed or simplified when necessary; Boundary rope: The steel wire rope used to close the four perimeters of the protective net is divided into upper boundary rope, lower boundary rope and side boundary rope according to its position. A steel wire rope anchor rod with a length of 2~3m is provided at each end; Auxiliary anchor: optional. It is used to make SPIDER net better adhere to the slope surface in local depressions. Compared with the main anchor rod, its diameter can be approximately small, generally 20~25mm, and the length is generally 1~1.5m. The anchor pad can also be used. Appropriately reduce.
