The noose mesh is a new active protection form with high-strength steel strand spiral mesh as the main body.

Main components: SPIDER high-strength steel strand spiral mesh, prestressed steel anchor, special anchor plate

Fixing method: prestressed steel anchor rod, special anchor pad fastening

Bearing capacity: better than all current flexible slope stabilization systems

DESIGN METHOD: DESIGN SYSTEM BASED ON RUVOLUM THEORY

Scope of application: overall stable reinforcement of soil slope and rock slope, reinforcement of various solitary rock dangerous rocks, and slip treatment can also be combined with deep anchoring measures

Breaking tensile force: 195~220 kN/m

Mesh shape: diamond

The noose mesh is made of high-strength anti-corrosion steel wire after forming a cable, the diameter of the diamond mesh is 250mm, and the standard specification of the mesh is 10x3.5m;

Bolting: generally use Φ25/28 ordinary rebar anchor with processing thread at one end (exposed section), can also use Φ25 fine-rolled rebar (such as GEWI bolt), and according to the need for hot-dip galvanizing and other anti-corrosion treatment, self-drilling hollow bolt can be used when the hole is difficult;

Anchor pad: diamond-shaped steel plate, four corners with clasp jaws, size not less than 320x180mm, thickness not less than 10mm; its structure can be changed or simplified when necessary;

Boundary rope: used to close the four perimeter of the protective net wire rope, according to its position is divided into upper boundary rope, lower boundary rope and side boundary rope, its diameter shall not be less than Φ12, generally choose Φ14 or Φ16, a single length should not be greater than 40m, each end is equipped with a length of 2~3m wire rope anchor;

Auxiliary bolt: optional. It is used to make the SPIDER net better close to the slope in the local low depression, relative to the main bolt, its diameter can be about small, generally 20~25mm, the length is generally selected 1~1.5m, and the anchor pad can also be appropriately reduced.
