Product Description:

Gabion basket is woven from low-carbon steel wire treated with anti-corrosion technology. The mesh is shaped like a hexagon. The cage has a spacer per meter and is divided into independent units.

Gabion basket is an ecological grid structure. The stone cage net is mechanically woven from low-carbon steel wire with high corrosion resistance, high strength and ductility or PVC-coated steel wire. The box-shaped structure made by the net is the stone cage. The diameter of the low carbon steel wire used varies according to engineering design requirements. Generally between 2.0-4.0mm, the tensile strength of the steel wire is not less than 38kg/m2, and the metal coating weight is generally higher than 245g/m2. The diameter of the edge wire of the gabion mesh is generally larger than the diameter of the wire. The length of the twisted part of the double wire shall not be less than 50mm. To ensure that the metal coating and PVC coating of the twisted part of the steel wire are not damaged.

Gabion Basket Application:

The structure can be used for side slope support, foundation pit support, mountain rock surface hanging net shotcrete, side slope vegetation (greening), railway highway isolation fence, it can also be made into box cages, net pads, used in rivers, rivers, Erosion protection of dams and seawalls, as well as cages for the closure of reservoirs and rivers.

• Control and guide rivers and floods

The most serious disaster of rivers is the destruction of river banks by water, which caused flooding, resulting in massive losses of lives and properties and massive soil erosion. The application of the ecological gabion net structure can permanently protect the river bed and bank.

• Channel canal bed

The construction of the channel involves the stability of the slope and river bed. It can effectively and permanently protect the river bank or riverbed, control the flow of water, prevent water loss, and has excellent effects in environmental protection and water quality maintenance.

• Slope protection

The application of ecological grid structure to river bank protection and slope toe protection is a very successful example. It gives full play to the advantages of ecological grid and achieves the ideal effect that other methods cannot achieve.

Advantages of gabion basket structure:

1. The flexible structure can adapt to the changes of the slope without being destroyed, and has better safety and stability than the rigid structure;

2. Strong anti-scouring ability, can withstand the maximum water flow speed up to 6m/s;

3. The structure is inherently water-permeable, and has strong tolerance to the natural and filtering effects of groundwater. Suspended matter and silt in the water can be deposited in the rockfill, which is beneficial to the growth of natural plants. 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.
