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 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.
