Stone cage net material, application specifications
Stone cage net use introduction:
The structure can be used for slope support, foundation pit support, mountain rock face hanging net shotcreting, slope planting (greening), railway highway isolation guard net, it can also be made into cages, net mats, used for rivers, Anti-scour protection for dams and seawalls, and cages for reservoirs and river closures.
The most serious disaster that controls and guides rivers and flooded rivers is that water flows through the river bank to destroy it, causing flooding, resulting in heavy losses of life and property and massive soil erosion. Therefore, in dealing with the above problems, the application of the ecological grid structure is one of the best solutions, which can permanently protect the river bank.
The construction of channel canal riverbed channels involves the stability of slopes and riverbeds. Therefore, the choice of ecological grid structure is the main method used in many natural river reconstruction and artificial channel excavation in the past 100 years. It provides effective permanent protection for river banks or riverbeds. It also has the function of controlling the flow of water and preventing water loss, especially in environmental protection and water quality maintenance.
The application of the ecological grid structure of the bank protection slope protection and the protection of the river bank and its slope protection are very successful examples. It fully exerts the advantages of the ecological grid and achieves the ideal effect that other methods cannot achieve.
Advantages of the ecological grid structure:
1. The flexible structure can adapt to the change of the slope without being damaged, and has better safety and stability than the rigid structure;
2, strong anti-scour ability, can withstand the maximum water flow speed of up to 6m / s;
3. The structure is water-permeable in nature, and has strong inclusiveness to the natural action and filtration of groundwater. Suspended matter and sludge in the water can be deposited in the rockfill joint, which is conducive to the growth of natural plants. Restore the original ecological environment. The stone cage net is made of a single layer of mesh. Its mesh, mesh, galvanized and PVC film properties are the same as those of the cage. This product can pack blocks of different shapes and sizes into alloy net pockets to form a flexible whole. It can be connected to a designated place by lifting, car and shipping, and the alloy net pockets are connected to each other to form a larger whole. The investment time is convenient, fast, efficient and economical.
Material classification of stone cage net:
(1) galvanized steel wire: high-quality low-carbon steel wire, the diameter of steel wire is 2.0MM-4.0MM, the tensile strength of steel wire is not less than 380Mpa, the surface of steel wire is protected by hot-dip galvanizing, and the thickness of galvanized protective layer is according to customer requirements. Produced, the maximum amount of galvanizing can reach 300g/m2.
(2) Zinc-5% aluminum-mixed rare earth alloy steel wire: (also known as Galvan) wire, which is a new emerging material emerging in recent years. The corrosion resistance is traditionally pure galvanized. More than 3 times, the diameter of the steel wire can reach 1.0MM-3.0MM, and the tensile strength of the steel wire is not less than 1380Mpa.
(3) Galvanized steel wire plastic coated: high-quality low-carbon steel wire, coated with a layer of PVC protective layer on the surface of the steel wire, and then woven into hexagonal nets of various specifications. This layer of PVC protective layer will greatly increase the protection in a highly polluted environment, and through the choice of different colors, it can be integrated with the surrounding environment.

Classification of stone cage nets 1. Net cage It is a wire mesh cage which is cut and folded by heavy-duty hexagonal nets. It is generally assembled by 4 pieces of heavy-duty hexagonal nets. It is a large hexagonal net folded and expanded into 4 large squares. Face, there are two small pieces of hexagonal net on both ends, with a partition mesh in the middle. The cages of the stone cage net can also be made into triangles and trapezoids. The dams of the cages are caged on a plane. The gabion cage is often used in the retaining wall of the water conservancy project. The gabion net retaining wall is a retaining wall made up of cages of 0.5-1.0 m. The gabion cage retaining wall is mainly used for steep hillsides. It is used to control mudslides, prevent landslides, and protect roadbeds and railways. The reason why the cage cage is used is because the cage cage has a unique ecological function. Green soil can be sprinkled on the surface of the protective body. Because the gap between the stone and the stone is filled with voids, the gap accommodates the soil, which is conducive to the development of plant roots and creates a good ecological environment. Even if you don't sprinkle the soil, the gap between the stones will be buried in the soil over time, which will grow some herbaceous plants and form a natural ecological environment. After the production of the gabion cage, in order to save the volume, the compression package can be bundled.
Second, the pad, is a heavy-duty hexagonal net cut, folded metal cage, the thickness of the stone cage mesh pad is 0.15 meters - 0.5 meters. The stone cage mesh pad is divided into several cells by the partition plate. In order to strengthen the strength of the stone cage mesh pad structure, the wire diameter of each wire mesh edge of the stone cage mesh pad is relatively thick. It is mainly used as a river course, a bank slope, a roadbed slope, and a coastal slope protection structure. The stone cage mesh pad has a certain flexibility and adapts to the ground. Like the gabion net cage, the gabion mesh pad can also be divided into several cells by the mesh partition of the hexagonal net, which can increase the strength of the pad, and prevent the river bank from being affected by water flow and wind and waves. The damage also realizes the natural convection function between the water body and the soil under the slope, achieving ecological balance. The stone cage mesh pad throws the soil and can plant green vegetation. The green planting on the slope can increase the landscape greening effect. Knowledge: Why is the pad called the gabion mesh pad? Because it is a pad-type engineering component whose thickness is much smaller than the length and width of the gabion cage.
Third, the stone cage net retaining wall is a retaining structure of the stone cage net cage stacked. The components of the gabion cage retaining wall are filled with stones of similar size and proportion in the cage, so that there is a certain porosity. Due to the gap between the stones, the soil behind the masonry and the soil layer under the slope can be discharged. The water, thus reducing the water level, reducing the surface water pressure behind the wall and under the slope, the timely discharge of water reduces the probability of the retaining wall being destroyed, so that the life of the retaining wall will be greatly extended. At the same time, the wall cage is a cage made of wire mesh, which can have a certain deformation. Moreover, between the stone and the stone, it can also slide, so the deformation ability of the retaining wall can also buffer the sudden external force.
4. There are two kinds of gabion nets for roads. One is to protect roads. For example, on the side of the road, a gabion net dam is built with gabion cages to resist flood protection roads; On the side, the gabion net is used to reinforce the subgrade with a gabion cage. The other is to place the heavy-duty hexagonal net on the roadbed or cast concrete pavement during the construction of the road, as a reinforced net, placed in the cement pavement, so as to prevent cracking of the pavement. The shore of the artificial land.
5. The stone cage net roll, the gabion net is woven into a mesh of 30 meters to 50 meters, rolled into a roll, directly laid on the slope surface, to protect the slope, prevent soil erosion, rock collapse, and can also be used for slope support Protection, foundation pit support, mountain rock face hanging net shotcrete, slope planting (greening), railway expressway isolation barrier, river, dam and seawall anti-scour protection.
