Gabions are double twisted hexagonal woven galvanized steel wire mesh compartmented baskets with a rectangular box shape. The compartments or cells are of equal size and dimension and are formed by internal diaphragms being placed within the basket. The compartments or cells are filled with natural stone and the diaphragms minimize stone migration within the basket providing even distribution of the stone fill throughout the basket even after structural movement.
The 'baskets' come in a variety of dimensions, generally 1m wide x 1m deep x 1-4m long, and a selection of mesh sizes to suit the various applications. They are relatively cheap, at £30-£50 each and by using local random stone, generally in chunks 100-200mm, and being very simple to install, the cost is kept to a minimum, and the finished result is aesthetically pleasing.
The gabions can be 'stacked' to create structures up to around 10m high. The bottom gabions are placed, wired together and filled with stone, before wiring on the 'lids' and positioning the next course, stepped back from the face of the lower course by 200-300mm.
The 'natural' look of gabions, compared to, say, reinforced concrete, make them a most attractive alternative for many schemes, such as the river bank erosion control project shown opposite.
Uses:
Gabions are used in many several situations including the stabilization of the earth movement and erosion, river control, reservoirs, canal refurbishment and retaining walls. The are designed in welded mesh or woven wire, welded mesh gabions are faster to erect and do not need tensioning
Flexibility
One of the most important advantages of double twisted mesh gabions & reno mattresses is their flexibility both for the individual unit and the overall gabion or reno mattress structure. The Double Twisted Hexagonal Mesh construction of the units permits it to tolerate differential settlement without failure. This property is especially important when a structure is on unstable soil conditions or in areas where scour from wave action or currents can undermine the toe of the structure and cause structural settlement.
Durability
Gabions & Reno Mattresses built from high strength double twisted hexagonal mesh filled with natural hard durable stone and connected together to create a monolithic mass structure capable of undergoing structural movement without any loss of structural integrity creating a highly durable structure.
Strength
Double Twisted Hexagonal Mesh Gabions & Reno Mattresses possess the strength and flexibility to withstand forces generated by water and earth masses. The most important and relevant strength characteristics pertaining to gabion and reno mattress design standards are the mesh punch strength, the mesh tensile strength, the pull apart resistance strength of the mesh, and the corrosion resistance of the mesh. The strength values of the double twisted mesh are located within the individual product specifications for each product and are represented in ASTM A975-97.
Permeability
Gabions & Reno Mattresses create structures that are naturally free draining. Hydrostatic heads do not develop behind gabion and reno mattress structures. Drainage is accomplished by gravity and by evaporation as the porous structure permits an active air circulation through it. Moreover, as soil is deposited and plant growth invades the structure, transpiration further assist in removing moisture from the soil being protected.
Ecology Gabions & Reno Mattresses offer an environmentally sensitive solution to soil retention slope stabilization. Gabion and reno mattress structures utilize natural stone for their stability and strength. Constructed of natural stone fill the gabions are naturally porous allowing interaction between the land and the water table. Soil will generally be deposited in the small voids of the stone fill material during drainage and draw down and will promote vegetated growth inundating the structure. Over time in some applications the structure can become so inundated with vegetation as to no longer be visible. Vegetation, plant and tree growth can be implemented at the time of construction utilizing several methods to ensure vegetation occurs immediately.
Reliability The overall strength characteristics offered by the double twisted hexagonal mesh gabion and reno mattress listed above and the long successful history of the material usage world wide ensures that the double twisted mesh gabions and reno mattresses will perform as designed.
Low Construction Cost
Gabions & Reno Mattress installations are very cost effective. Gabions & Reno Mattresses are easy to construct requiring limited equipment, unskilled labor, minimal foundation preparation, no drainage provisions, and low cost stone fill generally provided by a local stone or rock supplier. Gabion & Reno Mattress structures require very little if any maintenance and if designed and built properly can be a permanent structure.
Aesthetics
Gabions & Reno Mattresses constructed with care can create visually pleasing structures. Unlike other types of materials such a modular block walls the gabion stones do not discolor due to drainage. In fact the longer a gabion or reno mattress structure is in place and becomes inundated with vegetation the more aesthetic it becomes.
Mesh box is point to heavy hexagonal mesh is also named gabion mesh.
In order to reinforce gabion mesh configurable intensity, all of the face halftone side adopt more thick steel.control and lead to water or flood ,water and soil protection, keep off dust wall.
Characteristics :
- Economy. It only needs to load a stone cage can be sealed.
- Construction is simple, without special skills.
- A strong withstand natural damage and corrosion resistance and resistance to adverse effects of climate.
- Withstand large-scale deformation, and does not collapse.
- Cage rock crevice between the mud to plant production, with the surrounding natural environment melting together.
- Has good permeability to prevent static fluid from the damage caused.
- Save transportation costs. Can be folded up its transport, assembly on site.
usage:
- Control and guide of water or flood
- Preventing of rock breaking
- Rock fall protection
- Water and soil protection
- Bridge protection
- Strengthening structure of soil
- Protection engineering of seaside area.
- Port project
- Keep off dust wall
- roadway protection.
Gabion box Protect mat thickness is between 0.15-0.5.. mainly used in riverway, shore , and roadbed slope. It can prevent the riverside was destroyed by stream and storm. And also implement the exchange of water and earth under the slope. Achieve the zoology balance. Planting on the slope is beautiful and can make the slope virescence.
Heavy hexagonal wire netting also can be made into hang mesh, used for roadbed, and prevent rockfall and plasm gushing.
Heavy hexagonal wire netting also can be made into mesh bag, made of monolayer mesh sheet. Used for father and leading of riverway. The mesh , wire diameter, galvanized and PVC peritoneum is same as gabion box.
Heavy Hexagonal wire netting also can be made into mesh cage. Thickness is: 0.5-1.0m. character is similar to gabion box. Bowel can fill rock and sand. Exterir can be covered with sand and vegetation.
double twist wire mesh usual specification(special specification can made to the order)
Heavy hexagonal mesh is also named big specification hexagonal mesh (big aperture hexagonal mesh, big wire hexagonal mesh ),it’s using high quality wire tweak weave and machine weave twisted-pair hexagonal mesh wire. Heavy hexagonal mesh have wide range of uses. For example; border slope timbering, it can made inyo box to protect dyke , reservoir, river flowing ect.
1. Galvanized big wire hexagonal mesh use of low carbon steel wire weave, the steel wire of tensile strength of not less than 38kg/m²,steel wire diameter also can reach 2.0-4.0mm, the surface of steel wire use adopt hot galvanized to protect, the thickness of galvanized protect we can make it as your requires. the galvanized we can maked to 300g/ m²。
2.Galvanized dipped plastic hexagonal mesh is coated PVC with galvanized wire surface then weaved to various specification hexagonal mesh. The protect of PVC can increase the mesh's life, and through different color choices, and it can be integrated with the surrounding natural environment.
Heavy hexagonal mesh surface dispose to hot dipped, electro, PVC dipped.
Heavy hexagonal mesh (big aperture hexagonal mesh) can made to wire mesh fence,(seclusion bar) use, it’s substitutes of chain link fence.
Heavy hexagonal mesh by make of screw weave, it’s burliness than chain link fence. Chain link fence is indefinite but hexagonal mesh’s wire is screw disturb together .
