PVC Coated Galvanized Iron Wire Mesh Gabion Basket Galvanised For Bridge Protection In France

Gabion Cage Description :

Gabion basket, also known as gabion box and gabion net, is a new type of ecological grid structure. It has been successfully applied to water conservancy projects, highways, railway projects and dike protection projects, and has well realized the organic combination of engineering structure and ecological environment. At the same time, compared with the traditional rigid structure, it has its own advantages and has become the preferred structural form for riverbed, landslide, debris flow, rockfall protection and environmental protection worldwide.

Gabion basket is made of twisted hexagonal woven mesh. The metal wire used to make gabion baskets is made of soft tensile heavy galvanized steel, and PVC coating can also be used for additional corrosion protection when the application requires. The double twisting of the woven wire mesh provides structural integrity, strength and continuity by increasing the non-loosening effect of preventing any accidental damage from spreading. Fastening wires are used to assemble and interconnect empty units and to close and fix stone filling units. Once assembled, the basket will be filled with stones at the scene.

 
Gabion Cage Material :

1. hot-dip galvanized low carbon steel wire,
2. Zinc-5%Al or10%Al-mixed rare earth alloy coating, also named Galfan. lifetime 3times min than hot-dip galvanized gabion.
3. PVC coated , PVC coated on hot-dip galvanized steel wire and Galfan, many kinds of color
4. Tensile strength: 350-500Mpa,Elongation ≥12%,according to EN10223-3
5. zinc coating: mesh wire≥230g/M2,selvedge wire≥245g/M2,lacing wire ≥230g/M2
 
Gabion Cage Applications :
• Control and guide of water or flood
• Flood bank or guiding bank
• Prevention of rock breaking
• Water and soil protection
• Bridge protection
• Strengthening structure of soil
• Protection engineering of seaside area
• Seaport engineering
• Isolation walls
• Protection of road

Retaining Gabion Basket Advantages:

1).Flexible structure to adapt to changes in the slope without being destroyed, better than the rigid structure with the security and stability;

2).Anti-erosion ability, able to withstand the maximum flow rate of up to 6m / s .

3).This structure has essentially permeability, groundwater and the filtering effect of the natural role of a strong inclusive, suspended matter and silt in the water to move in to fill the crevice in precipitation, which is conducive to the growth of natural plants, and gradually restore the original ecological environment.

Gabion Basket Installation Process:

1. Ends,diaphragms,front and back panels are placed upright on the bottom section of wire mesh

2. Secure panels by screwing sprial binders through the mesh openings in adjacent panels

3. Stiffeners shall be placed across the corners, at 300mm from the corner. Providing a diagonal bracing,and crimped

4. Box gabion filled with graded stone by hand or with a shovel.

5. After filling,close the lid and secure with sprial binders at the diaphragms,ends,front and back.

6. When stacking tiers of the weled gabion,the lid of the lower tier may serve as base of the upper tier.Secure with sprial binders and add pre-formed stiffeners to exterior cells before filling with graded stones.
