Stone cage net
The stone cage net is made of high corrosion resistance, high strength, low carbon steel wire with the extension of the steel wire or the steel wire coated with PVC, and the box structure made of the net is a stone cage. According to ASTM and EN standards, the low carbon steel wire diameter is different according to the engineering design requirements. Generally between 2.0-4.0mm, the tensile strength of steel wire mesh cage is not less than 38kg/m2, the metal coating weight is generally higher than 245g/m2, the diameter of the edge of the stone cage mesh is generally greater than the diameter of the wire. The double stranded part of the length of not less than 50mm. to ensure that part of the wire strands of metal plating and PVC coating damage.
The slope vegetation (green), railway highway isolation fence, it also can be made into trunks, mat, for protection against erosion of rivers, dams and seawall, reservoirs, river closure with cage. River is the most serious disaster is the flow of water to the river bank to destroy, causing flooding, resulting in a large number of loss of life and property and a large number of soil and water loss. Therefore, in dealing with these issues when the lattice structure of the eco grid application has become one of the best solution, it can be permanent river bank protection.
1, the flexible structure can adapt to the change of the slope and not be destroyed, and has better safety stability than the rigid structure;
2, strong anti erosion ability, can withstand the maximum flow rate of up to 6m/s;
3, the structure has a permeable nature, has a strong inclusive effect on the nature of groundwater and filtration, suspended matter and silt to be deposited on filling of cracks in the water, which is conducive to the natural growth of plants, and gradually restore the original ecological environment.
The stone cage net is a wire or a polymer wire mesh format to make the filling stone fixed in place. Wire cages are made of steel wire mesh or welded structure. These two kinds of structures can be plated, braided wire can be additionally coated with PVC. With the hard rock as anti weathering filler, it will not sinking due to erosion and soon broken stone in the box or the stone cage. Stone cages fitted with different types of blocks have different characteristics. Stone can each other very well in multi angle interlock together, with the stone cage filling is not easy to deformation. In landscape engineering, highway slope, dam revetment and mountain steep slope greening is always a difficult problem in engineering and technical personnel. Over the years, they have been exploring a process, not only to meet the requirements of the mountain, beach and stability of the protection, but also to achieve the effect of green environment, but also economic and convenient. Gradually, this process began to emerge, it is the ecological stone cage net application technology. Dong Lei Anping hardware wire mesh products factory has developed into a set of production, processing and sales of stone cage net for the integrated enterprise, the factory stone cage net product varieties of products are mainly used in slope protection, retaining wall, bridge, river protection, highway subgrade protection, slope protection, ecological river slope regulation engineering. Ecological stone cage net application technology is made of high strength galvanized steel wire woven into different specifications of rectangular cages, cages filled with the structure of the stone. This structure is applied to slope protection, in the dual role of natural and human factors, the gap between the stones have been filling soil. The soil seed gradually between the stones in the sprout and grow roots firmly fixed rocks and mud. So that it can achieve the purpose of slope protection and greening, improve the ecological, keep the effect of water and soil is also very significant. Ecological stone cage nets process has four aspects: one is the advantage of simple construction, the ecological process of the stone cage nets just a stone into the cage and sealing, no need of special technology, also do not need water. The two is a low cost, ecological gabion boxes per square meter cost only 15 yuan. Three is a good landscape and protective effect. Engineering measures and plant measures of ecological stone cage nets processes used in combination, can effectively prevent soil erosion, landscape quick, landscape effect is more natural and more abundant. The four is a long life, ecological stone cage nets process of life for decades, and generally no maintenance. It is precisely because of this, the berm project, the Huangshi section of the Yangtze River in Taihu flood control levee protection project, the Three Gorges Three Doo revetment projects have adopted this technology.

Weight calculation formula of stone cage net
Stone cage net is a metal wire woven angular network (six mesh) made of metal cages, use line diameter according to the size of the tiles. If is the metal coating metal line is hexagonal, use the diameter of 2.0mm to 4.0mm metal wire, if it is six mesh PVC metal wire coated woven, use the outside diameter of 3.0mm to 4.0mm PVC (metal) line at the edge of the box is used to line six line number one line.
The box type stone cage is formed by connecting a large size six angle net, which only needs to be sealed in a cage in the construction.
Rock cage specifications: X 1m x 1m 3M, X 1m x 1m 2m, X 1m x 1m 4m, X 1m x 0.5m 2m, X 1m x 0.5m 4m, but also according to customer requirements for production. Surface protection state of hot dip galvanized, galvanized aluminum alloy, coated PVC, etc..
