Roll size: 4m x 4m, 4.5m x 4.5m etc.
Grid net:: Wire diameter: 2.0mm or 2.2mm
Hole size: 50mm*50mm
Roll size: 2m*20m
Anchors: Deformed steel bar anchor diameter: 25mm or 28mm
Length:2m -5m
Anchor bearing plate: 320mm x 170/180mm
Rope: Border rope diameter: 12mm or 16mm
Seaming rope diameter: 8mm
(2) NACCO System
The NACCO System is the same as WICCO System, the only difference is that In NACCO System, there have a layer of plastic on the outside of the rope wire.
(3) TECCO System
The TECCO steel wire mesh is made by 3mm high-tensile steel wire. And with anchors the TECCO steel wire mesh covers over the slope tensioning and firmly.
Components
The TECCO system consists of the TECCO steel wire mesh, anchors, anchor bearing plate , border and suture ropes and net connection elements.
Standard Specification:
TECCO steel wire mesh: wire diameter::3mm,
Hole Inscribed circle diameter: 65mm (+/- 5%)
Roll size: 3.3m x 10/20/30m
Anchors: Deformed steel bar anchor diameter: 25mm or 28mm
Length:2m -5m
Anchor bearing plate: 320mm x 170/180mm
Rope: Border rope diameter: 12mm or 16mm
Seaming rope diameter: 8mm
Benefits:
Compared with other active protection system:
Only 60%-80% cost compare with the traditional wire rope system.
Fast and easy installation
(4) SPIDER System
The SPIDER spiral rope net made by high tensile 3 mm steel wire, which is the mainly component of the SPIDER System. SPIDER net with a layer of grid net stabilizes large areas of rock with anchors and boundary ropes. Unstable rocks are wrapped with a layer of spiral net and a layer of grid net and anchored all around with boundary ropes.
Components
The SPIDER system consists of the SPIDER spiral rope net, grid net, anchors, anchor bearing plate , border and suture ropes and net connection elements.
Standard Specification:
SPIDER spiral rope net: Rope wire structure:3*3mm,
Hole Inscribed circle diameter: 250mm (+/- 5%)
Roll size: 3.5m x 5/10m
Grid net:: Wire diameter: 2.0mm or 2.2mm
Hole size: 50mm*50mm
Roll size: 2m*20m
Anchors: Deformed steel bar anchor diameter: 25mm or 28mm
Length:2m -5m
Anchor bearing plate: 320mm x 170/180mm
Rope: Border rope diameter: 12mm or 16mm
Seaming rope diameter: 8mm
2, SNS Passive Protection System
(1) The Passive SNS shielding system
The Passive SNS shielding system is also called stone blocking mesh, made by flexible steel wire rope netting installed in the slopes to stop the falling rocks . It can also be installed in the mud-rock flow area to form the flexible fencing dam to stop the huge solid pellets in the flow.
Standard Specification:
Diamond wire rope net: Rope wire diameter: 8mm
Hole size: 200mm (+/- 5%)
Roll size: 4m x 5m, etc.
Grid net:: Wire diameter: 2.0mm or 2.2mm
Hole size: 50mm*50mm
Roll size: 2m*20m
Anchors: Steel Rope anchor diameter: 16mm
Length:2x2m
Rope: Border rope diameter: 12mm or 16mm
Seaming rope diameter: 8mm
Other Components: Steel Column, rope support base, vacuum ring
(2)Ring Network System
Ring network system is a passive protection system, a special branch, which has a passive protection system than the average strength of a higher character. The same applies to construction facilities in the buffer zone next to the mountains and little hills, the rock fall, flying stones, avalanches, landslides blocked the building facilities, building facilities to avoid the disasters on the destruction.
Common ring network structure configuration and protection features (Consistent with Railway Industry Standard: TB / T 3089-2004 and "The People's Republic of China Communication Industry Standard: JT/T528-2004)
