Hardware Knowledge Hall: The production and advantages of stone cage nets

Production: The gabion net is mechanically woven from low-carbon steel wire with high corrosion resistance, high strength, ductility or PVC-coated steel wire. The box-shaped structure made by using this net is a stone cage. According to ASTM and EN standards, 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 gabion wire is not less than 38kg/m2, the metal coating weight is generally higher than 245g/m2, and the diameter of the edge wire of the gabion mesh is generally larger than the diameter of the wire. The length of the double-stranded part shall not be less than 50mm. In order to ensure that the metal coating and PVC coating of the twisted part of the steel wire are not damaged.

Usage: Gabion net can be used for side slope support, foundation pit support, shotcrete hanging on mountain rock surface, side slope vegetation (greening), railway highway isolation fence, it can also be made into box cages and nets Mat, used for anti-scouring protection of rivers, dams and seawalls, as well as cages for the closure of reservoirs and rivers. The most serious disaster in rivers is the destruction of river banks by water, which causes flooding, which leads to massive losses of lives and properties and a large amount of soil erosion. Therefore, when dealing with the above problems, the application of this ecological grid structure becomes one of the best solutions, which can permanently protect the river bed and bank.

Advantages: 1. The flexible structure can adapt to the slope changes without being destroyed, and has better safety and stability than the rigid structure; 2. The anti-scouring ability is stronger, and it can withstand the maximum water flow speed up to 6m/ s; 3. The structure is inherently water-permeable, and has a strong tolerance for the natural and filtering effects of groundwater. Suspended objects and silt in the water can be deposited in the rockfill, which is conducive to the growth of natural plants , And gradually restore the original ecological environment.

The gabion net is a net-like production of iron wire or polymer wire that fixes the stone fill in place. The wire cage is a mesh woven or welded structure made of iron wires. These two structures can be electroplated, and the woven wire box can be additionally coated with PVC. Use weather-resistant hard rock as the filler, it will not be quickly broken due to abrasion in the stone box or gabion sink. Gabions containing different types of block stones have different characteristics. The multi-corner stones can be interlocked with each other well, and the stone cage filled with them is not easy to deform.
