Gabion

Stone cage net and gabion mesh, gabion mesh is commonly referred to as China in ecological green grid, in foreign countries, this product is made into a "box structure gabion". Mesh is the word "gabion" transliteration, concise English Dictionary of explanation is: bamboo basket, metal basket.

In China, ecological green grid structure originated 2000 years ago with the pen, craft, Li Bing and his son for the first time in the Dujiangyan project, which is the traditional sense of the mesh structure: now, as a new eco grid structure of new technology, new technology, new materials, successfully applied to water conservancy project, highway, railway engineering, embankment protection works. The organic combination of the engineering structure and the ecological environment has been realized. At the same time has its own advantages compared with traditional rigid structure, so in the world has become the protection of riverbed, landslide, debris flow prevention, prevent both environmental protection preferred structure of rockfall.

Suitable for high velocity, gabion mesh erosion, slope seepage of slow river. The stone cage is a flexible structure, and the self adjustment of the uneven settlement is better. Shore surface porous stone, the gap between to animal habitats, plant growth, above the waterline of the stone cage surface can be vegetation ecological considerations and safety requirements using soil bag.

The green grid structure is common in slope retaining stabilization, because of its economy, construction is convenient, can use local materials,

Fill in the soil, gravel and natural grading, etc., to quickly form a retaining soil or water retaining structure, so as to the engineering community is willing to adopt.

Two

Structure characteristics

(1) economy. Just put the stone into the cage can be sealed.

(2) construction is simple, without special technology.

(3) the ability to withstand natural damage and corrosion resistance and the impact of adverse weather.

(4) can withstand a large range of deformation, and still do not collapse.

(5) the silt in the gap between the cage and the stone is good for the production of plants, which can be fused with the surrounding natural environment as a whole.

(6) with good permeability, can prevent the damage caused by the hydrostatic.

(7) to save the cost of transportation. It can be folded up the transportation, at the site assembly.

(8) quickly, to rush deadlines: multiple simultaneous construction of parallel flow.

Generalization

The green grid mesh is widely used in transportation, water conservancy, municipal, landscape, soil and water conservation project in a new material structure. The eco grid corrosion resistant high strength low carbon high galvanized steel wire or 5%- ~ 10% thin aluminum zinc alloy coated steel wire (or homogeneous polymer coated wire), the machinery will be woven into double stranded twisted hexagonal shape, multi mesh mesh, the double hinge part length should be less than 125px, with protective coating no damage of steel wire. See industry standard YB/T4221-2010. According to the requirements of the engineering design of gabion net assembly boxes and loaded into the cage, stones and other filler together with new technology, embankment, subgrade protection project.

In order to ensure the wire material is not damaged in the process of weaving (such as in other steel and high carbon and alloy steel wire weaving equipment does not move, force will damage the wire material and woven coating etc.), construction is convenient, and the flexibility characteristics of steel wire can weave gabion mesh used for low carbon steel wire, absolutely can not be used the other wire; if in low carbon galvanized or 10% high aluminum zinc alloy coated steel wire on the surface of a thin layer of PVC or PE (do not use other polymers), the product structure is more rust proof, anti-static, anti aging, corrosion resistance, high compressive strength, high shear, can effectively resist the erosion of seawater or the height of the pollution of the environment.

Texture of material

(1): high quality low carbon steel wire galvanized steel wire, steel wire diameter 2.0MM-4.0MM, the tensile strength of the steel wire not less than 380Mpa, the surface of hot galvanized steel wire protection, protection of the thickness of the galvanized production according to customer requirements, the largest amount of zinc can reach 300g/m2.

(2) -5% zinc aluminum (10% aluminum) - rare earth alloy steel wire, steel wire (also called Gao Erfan), this is an international emerging emerging as a new material, corrosion resistance is 3 times more than traditional pure galvanized steel wire, steel wire diameter is 1.0MM-3.0MM, the tensile strength of not less than 1380Mpa.

(3) galvanized steel wire plastic: high quality low carbon steel wire, the steel wire's surface covered with a layer of PVC protective layer, and then woven into a variety of specifications of the six angle network. This layer of PVC protection will greatly increase the protection of the environment in high pollution, and through the choice of different colors, so that it can be integrated with the surrounding environment.

(4) zinc -5% aluminum (10% aluminum) - mixed rare earth alloy steel wire package: in the surface of the zinc -5% aluminum - mixed rare earth alloy steel wire covered with a layer of PVC protective layer.

Gabion

The parameters of grid

(1) aperture: 60*80mm, 80*100mm, 80*120mm, 100*120mm, 120*150mm

The double stranded part length not less than 50mm. to ensure that.0 is part of the wire strands of gold plating and PVC coating damage.

(2) the wire diameter: the stone cage nets three - wire diameter, wire, tie wire mesh edge

1 mesh in the range of 2mm-4mm

The 2 side is generally greater than 0.5mm-1mm thick wire mesh.

3 wire is generally less than the mesh, common to 2.2mm.

(3) wire pull: not less than 380N/mm 38kg/m2

(4) surface treatment

1 Zinc plating. The highest zinc content was 10g/m2. Poor corrosion resistance

2 hot dip galvanized steel. The highest amount of zinc can reach 300g/m2. Strong corrosion resistance

3 Galfan (zinc Aluminum Alloy). This is divided into two kinds of materials, zinc -5% aluminum mixed rare earth alloy steel wire, zinc -10% aluminum mixed rare earth alloy steel wire. Super corrosion resistance

4.PVC plastic package. The thickness of the plastic package is generally 1.0mm thickness, for example: after the 2.7mm package for 3.7mm. Strong corrosion resistance
