Composition and characteristics of plastic-coated stone cage net:
Plastic-coated stone cage net is also called green grid, Gabion net. Plastic-coated stone cage net is coated with galvanized steel wire. It is also a PVC steel wire. It means to wrap the PVC protective layer on the surface of the steel wire, and then weave it into various pore sizes of stone cage net. This PVC protective layer will greatly increase the protection of high pollution environment, and through the choice of different colors, it can be integrated with the surrounding environment.
1.Ecological function: Pores in green grid and mattress create conditions for water flow, facilitate natural exchange between water and soil, create living environment for organisms and microorganisms in water, thus enhancing water self-purification ability, protecting and improving water source and water quality. Pores in filling materials are deposited artificially or naturally. Soil creates conditions for greening and vegetation. Even if seeds are not scattered, plants will naturally grow to optimize, beautify the environment, improve and restore the ecological environment.
2.Permeability function: Retaining wall built with net box and slope protection paved with loose filling material in net box, with more voids, is conducive to the discharge of pore water in the backfill and soil layer under slope protection after masonry. Once surface water infiltrates into soil body, it can be used to discharge quickly through masonry to effectively reduce groundwater level, thereby reducing the backside of wall and downslope. Groundwater pressure. In landslide control and debris flow control projects, the timely discharge of water reduces the probability of wall damage, and the good deformation ability of the wall can effectively cushion sudden external impact.
3.Stability function: The green grid is a twisted grid structure specially woven by machinery. Local damage will not cause the overall damage of the cage. Green grid material has moderate deformation characteristics, linking the whole project into a whole without splitting. Even if uneven settlement occurs, the whole structure will not produce cracks or serious problems.
4.Simple construction: Green grid technology can produce semi-finished products according to design intention, factory production, construction site is assembled and finalized according to design drawing, then laid on the soil slope or excavated foundation pit, paved slope protection or masonry into cage retaining wall, filled with filling materials and covered with mesh. The operation is simple and easy to be disturbed by climate, and suitable. Suitable for mechanized operation, can ensure the construction quality and speed up the progress of the project. In the construction process of a construction unit, due to the influence of weather, the construction unit will transfer the workers who work as masonry retaining wall to do green grid slope protection.
5.Beautiful effect: The combination of green grid structure and the diversity of colors can provide us with a variety of structural design to meet the landscape requirements of different regions. At the same time, combining lawn planting and flower planting, we will be presented with a green retaining wall or slope protection.
6.Service life: The steel wire of green grid material is galvanized, PVC, galvanized, stainless steel and so on. The surface coating of the steel wire is more stable, which can effectively reduce the oxidation of the wire. It has the characteristics of corrosion resistance, anti-static electricity, anti-aging and anti-oxidation, and has longer service life. According to the experiment, plastics are immersed in 30_concentration hydrochloric acid for 10 days, plastics No discoloration, no cracking. It can be seen that even in highly polluted areas, the application of this material is absolute.
