The data of gabion net ecological grid retaining wall is evolved and developed from bamboo gabion net. The gabion project, like paper making and gunpowder, originated in China. Dujiangyan Water Conservancy Project, which has a history of more than 2000 years ago, used gabion made of bamboo strips to build dams at that time. Through the application and improvement of hundreds of years in modern times, it has presented a modern way of gabion ecological grid barrier. The layout has been a reticulated rectangular box made of galvanized steel wire fabric, filled with block stones or natural pebbles, and used for various water retaining works and anti scour structures.

Gabion net, also known as gabion net, heavy hexagonal net and lead wire cage, is an ecological grid structure. Gabion mesh is made of low carbon steel wire with high corrosion resistance, high strength and ductility or steel wire above PVC coating by mechanical weaving. The box structure made of this mesh is gabion. 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 is not less than 38kg/m2, and the weight of the metal coating is generally higher than 245g/m2. The diameter of the edge line of the gabion mesh is generally larger than the diameter of the mesh line. The length of the double stranded part shall not be less than 50mm to ensure that the metal plating layer and PVC layer of the steel wire in the bonding part are not damaged. Gabion mesh can be divided into four categories: gabion cage, gabion mesh cushion, gabion mesh retaining wall, road protection gabion mesh. Among them, gabion retaining wall, as a new type of retaining structure, has been used more and more because of its low cost, good ecology, wide scope of application, flexible deformation and other characteristics.

In landscape engineering, gabion net has always been a headache for engineers and technicians in highway slope protection, embankment revetment and mountain slope greening. For many years, they have been exploring a technology that can not only satisfy the protection needs of mountains and beaches, but also beautify the environment, and is also economical and fast. Over the years, this technology has begun to emerge, which is called ecological gabion network technology. The key technology of ecological gabion technology is gabion network. Because it is flexible planning, even in the case of land subsidence, collapse, landslide and other conditions, it can be resisted by its own deformation. The materials and knitting tips of the gabion mesh are very sophisticated. The steel wire used for weaving the gabion mesh is high-strength low-carbon galvanized steel wire. The surface is coated with plastic polymer optimized resin mold. It is highly resistant to rust, abrasion, erosion and cracking. The weaving method adopts twisted pair grid technology, which is to weave a twisted pair hexagonal mesh with gabion mesh. The twisted pair method binds the steel wires together to form a mesh. Even if one or two steel wires are broken, the mesh will not be untied, which is unusually robust. The ecological gabion technology is a plan that uses high-strength galvanized steel wire to weave a rectangular cage with different standards, and the cage is filled with stones. After this planning is applied to bank slope protection, the gap between stones is continuously filled with soil under the action of two layers of human and natural factors. The plant seeds gradually take root and germinate in the soil between the rocks, and grow healthily. The root system firmly fixes the rocks and soil. In this way, the intention of slope protection and beautification can be completed, and the role of ecological improvement and water and soil conservation is also very obvious Ecological gabion technology has four advantages. First, the construction is simple. The ecological gabion technology only needs to put the stone into the cage for sealing, without extra technology or water and electricity. Second, the cost is low. The cost of ecological gabion is only 18 yuan per square meter. Third, the scene and protection function are good. The combination of engineering method and plant method selected by ecological gabion technology can effectively prevent water and soil loss. The effect of the scene is fast, and the role of the scene is more natural and rich. Fourth, the use of the technology has a long life span. The technology of the ecological gabion network has a long life span of several decades, and usually does not need to be repaired. Gabion network has the advantages of high corrosion resistance, stability, durability, more economical project cost, good natural landscape and natural beauty. Many architects and landscape designers have begun to explore the excellent characteristics of gabion network, which can greatly benefit mankind in water construction and ecological environment. For the sake of engineering safety, experimental materials without international standards, such as 10% aluminum zinc alloy coated steel wire, must not be used. If a layer of PVC or PE (other polymers are not allowed) is coated on the surface of low carbon high galvanized or 5% aluminum zinc rare earth alloy steel wire, its product planning will be more rust proof, anti-static, anti-aging, corrosion resistant, high compression resistance, high shear resistance and other characteristics, which can effectively resist the corrosion of seawater or highly polluted environment.

For the sake of engineering safety, gabion mesh must not be manufactured with experimental data without world specifications, such as 10% aluminum zinc alloy coated steel wire. If a layer of PVC or PE (no other polymer is allowed) is coated on the surface of low carbon high galvanized or 5% aluminum zinc rare earth alloy steel wire, its product layout will be more rust proof, anti-static, anti-aging, corrosion resistant, high compression resistance, high shear resistance and other characteristics, which can be useful to resist the corrosion of seawater or highly polluted environment. The advantage of ecological mesh is that the low-carbon high galvanized steel wire with corrosion resistance, wear resistance and high strength or the steel wire with 5% aluminum zinc rare earth alloy coating (or the steel wire with polymer coating of the same material) is mechanically twisted into a multi stranded and hexagonal mesh mesh. The length of some of the twisted twin wires should not be less than 5cm, so as not to damage the protective coating of the steel wire. The ecological grid can be assembled into a box cage according to the design requirements of the project, and connected into a whole after being filled with filling materials such as block stones, which can be used as a new skill for embankment, subgrade protection and other projects. The mesh is made of annealed and hot-dip galvanized or hot-dip galvanized 5% aluminum zinc rare earth alloy welded gabion cage, which is another type of gabion mesh arrangement different from gabion mesh. It is made of high galvanized steel wire and has strong robustness and corrosion resistance. In order to improve the service life of welded gabion mesh, our factory has introduced PVC or PE cladding skills through strict standardized tests. Now this skill has been skillfully applied to the production process of welded gabion mesh. Through years of production and R&D, it has been able to produce various standard welded gabion mesh cages. In addition, according to the different needs of customers, we can also skillfully process the steel wire of Galfan gabion mesh with samples, zinc - 5% aluminum - mixed rare earth alloy steel wire: this is a new type of data in the world these years. The corrosion resistance is more than three times that of traditional pure galvanizing, the diameter of the steel wire can reach 2.0MM-4.0MM, and the tensile strength of the steel wire is not less than 380Mpa. The gabion mesh is a twisted hexagonal metal cage made of anti-corrosion, wear-resistant, high-strength low-carbon galvanized steel wire, According to the engineering design requirements, it is an engineering skill to assemble and load fillers such as block stones. This honeycomb layout best fits the principle of mechanics. It is an infinite block layout with the same nature, which can accept tension and absorb unknown pressure. This skill can better complete the organic connection between the project layout and the ecological environment. It is the preferred layout mode for maintaining river channels, managing landslides, preventing debris flow disasters, and avoiding rockfall to coordinate environmental maintenance. Gabion mesh is a hexagonal honeycomb cage woven from metal mesh. The metal wire used for gabion mesh is galvanized to improve its corrosion resistance. In some places with poor water quality (such as low pH value) and high demand for project life and quality, a specially optimized anti-corrosion polyvinyl chloride resin (PVC) can also be coated on the galvanized line. The product layout has the characteristics of rust prevention, anti-static, anti-aging, corrosion resistance, high compression resistance, high shear resistance, etc. It can be used to resist the corrosion of salt water or high pollution. The placement of the gabion network also needs to pay attention to many questions!

Gabion gabion mesh and cushion are usually folded and bundled to the construction site. The cover can be divided into two methods: split type and combined type. 1. Turn over each group of gabions or pads on the flat site adjacent to the construction site, level the folded parts, and prevent damage to the cage body and the external maintenance layer of the network cable; 2. The cage body is assembled into a rectangular shape with binding wires. There are usually two binding methods, one is connecting and looping, and the other is binding at a certain distance. The binding distance is usually 200~300mm. The binding method can be selected according to the drawing requirements. 3. The assembled cage device shall be placed in the required position and tied with the adjacent cage. The prepared stones or pebbles shall be filled into the cage. Proper arrangement shall be made to achieve high density. The diameter of the stones shall be twice larger than that of the mesh. The stones shall be selected with strong weathering resistance. Tie bars are used to maintain the regularity of cage shape, and the distance between tie bars is usually about 300mm. 4. After the filling of stones, cover the cage, regulate the cage edges, and bind and connect them. If split cage is selected, the cage shall be laid after all the cages are filled, and the cage shall be bound in sequence along the cage and the edge of the spacer. The cage can be covered with soil and beautified according to the actual situation. Gabion mesh (gabion gabion) refers to a box shaped mesh cage formed by a machine woven double stranded hexagonal metal mesh surface, which is divided into several cells by a partition (double stranded hexagonal metal mesh) 1m away. In order to strengthen the strength of the layout of gabion cages, steel wires with larger diameters are used at the edges of all surface mesh plates. Mesh standard of gabion cage: 6 × 8cm 8 × 10cm 10 × 12cm 12 × 15cm Diameter of gabion cage wire: 2.0-4.0mm (Note: to enhance the stability of the mesh itself, the edge wire shall be 1mm larger than the mesh wire) Raw material of gabion cage: hot galvanizing, electroplating, PVC coating, Gao'erfan [galvanizing (zinc content): electroplating: 10-25g/㎡; hot plating: 30-300g/㎡] : The layout can be used for side slope support, excavation, rock mesh eruption concrete, side slope vegetation (green), railway and highway barrier blocks, which can be made into cages and mats for river, pond dam and seawall erosion protection, reservoir and river closure cage. Controlling and guiding rivers and river flood disasters are the most serious water and river corrosion damage, resulting in numerous floods, endless loss of life and many water and soil loss of the industry. Therefore, in dealing with these questions, the application of ecological grid layout becomes the best solution, which can protect the bank forever. The channel canal channel construction, associated slope and channel stability. Therefore, the selection of ecological grid layout for steel grating is the primary method for natural river reconstruction and artificial river excavation for more than 100 years. It is useful for permanent maintenance in banks or beds. It also controls the flow of water to prevent water loss, especially in environmental and water quality maintenance. The application of ecological grid layout for bank protection and slope protection and the maintenance of river bank protection and toe are very successful. For example, the ecological grid that gives full play to its advantages and other methods cannot achieve the expected effect.
