The gabion mesh is made of high-corrosion, high-strength, and ductile low-carbon steel wire or the above steel wire covered with PVC using mechanical weaving. The box-shaped structure made of this mesh is the gabion cage. According to ASTM and EN standards, the diameter of low carbon steel wire used varies according to engineering design requirements. Generally between 2.0-4.0mm, the tensile strength of the steel wire of the gabion mesh is not less than 38kg/m2, the weight of the metal coating is generally higher than 245g/m2, and the diameter of the edge line of the gabion mesh is generally larger than the diameter of the mesh wire. The length of the twisted part of the double wire 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.

Gabion net can be used for slope support, foundation pit support, hanging net shotcrete on mountain rock surface, slope vegetation (greening), railway and expressway isolation protection and blocking net, it can also be made into cages, net pads, used in rivers and rivers , anti-scour protection of dams and seawalls, and cages for reservoir and river closure. The most serious disaster of the river is that the water flow scours the river bank to destroy it, which causes flooding, which leads to a lot of loss of life and property and a lot of soil erosion. Therefore, when dealing with the above problems, the application of the ecological grid structure has become one of the good solutions, which can protect the riverbed and banks for a long time.

A gabion net is a wire or polymer wire mesh-style fabrication that holds rockfill in place. A wire cage is a structure made of woven wire mesh or welded. Both structures can be galvanized and the braided wire box can be additionally coated with PVC. It is filled with weather-resistant hard stones, which will not be broken quickly due to abrasion in the stone box or gabion sinking. Gabions containing different types of boulders have different properties. The polygonal blocks can be well interlocked with each other, and the gabion filled with them is not easily deformed. The application process of ecological gabion net is to weave high-strength galvanized steel wire into rectangular cages of different specifications, and the cage is filled with stones. After this structure is applied to the bank slope protection, under the dual action of human and natural factors, the gaps between the stones are continuously filled with soil. The plant seeds gradually took root in the soil between the stones and grew vigorously, and the roots firmly fixed the stones and soil. In this way, the purpose of protection and greening of the slope can be achieved, and the effect of improving ecology and maintaining soil and water is also very significant.

The ecological gabion cage technology has four advantages:

First, the construction is simple. The ecological gabion cage technology only needs to put stones into the cage and seal it. It does not require special technology or water and electricity.

Second, the cost is low, and the cost per square meter of ecological gabion cages is low.

Third, the landscape and protection effect is good. The combination of engineering measures and plant measures adopted in the ecological gabion cage technology can effectively prevent soil erosion, the landscape is quick to achieve, and the landscape effect is more natural and richer.

Fourth, the service life is long. The ecological gabion cage has a technological life of several decades, and generally does not need maintenance.
