Gabion net is a common structure in protection engineering. It is mainly divided into two categories, one is with a metal coating on the surface, and the other is with PVC/PE coating on the surface. The production process of the gabion net goes through the processes of weaving, shearing, stitching, and binding, and finally made into a gabion net box, which is mainly used as a side slope protection structure for river courses, riverbank slopes, and subgrade slopes. The gabion net can not only prevent the river bank from being damaged by water currents and wind waves but also realize the natural convection exchange function between the water body and the soil under the slope, so as to achieve the effect of ecological balance. Gabion nets generally have the following specifications: 2m x 1m x 1m, 3m x 1m x 1m, 4m x 1m x 1m, 2m x 1m x 0.5m, 4m x 1m x 0.5m.
Today, wire mesh product manufacturers want to introduce two different types of gabion nets. They are chain link gabion nets and welded gabion nets. Let's take a look!
One, chain link fence
The chain-link fence is a long structure. The processing technology adopts the latest environmental protection technology. During the construction process, the chain link fence is filled with stones to form an integral material with flexible structure and strong permeability, which is beneficial to promote natural The rapid growth of plants. The chain-link fence is different from the traditional protection structure. In the river improvement project, the traditional riverbank revetment or slope protection structure generally uses mortar and masonry or concrete as the main raw material. The impervious performance does not meet the needs of natural ecological river management. Be eliminated by people. The chain link gabion net has strong erosion resistance, strong water permeability, and at the same time is a porous structure that is easy for organisms to inhabit, so it is often used in the construction of multi-natural ecological rivers.
2. Welded gabion net
Welded Gabion is a cage made of high-quality steel wire welded. Packing blocks or natural pebbles in the box can be used for highways, slope protection, shaft protection, bridge protection, retaining walls, etc. It has the advantages of permeability and integrity.
There are two materials of the welded gabion net. (1) Galvanized steel wire: The diameter of the steel wire is between 2.0MM and 4.0MM, and its tensile strength is greater than or equal to 350-520Mpa. The surface of the steel wire is treated by hot-dip galvanizing. The thickness of the galvanized protective layer can also be According to customer requirements, under normal circumstances, the amount of galvanizing will be around 260g/m2, and the maximum can reach 360g/m2. (2) Galvan steel wire, the galvanized layer of this low-carbon steel wire is an alloy, which is a recent The new material used here has a corrosion resistance of more than 3 times that of the traditional pure galvanized gabion net, the diameter of the steel wire is between 1.0MM-3.0MM, and the tensile strength of the steel wire is 350-520Mpa.
