Polyester biaxially stretched welded geogrid is made of polyester as the main material, adding anti-aging agents and other additives, and is mechanically stretched at low times into refined ribs. Welded and formed geosynthetic materials, different mesh diameters, rib widths, and thicknesses are used to change the tensile force of the ribs according to project needs
Product characteristics
The tensile force of polyester bidirectional tensile welded geogrid It is borne by warp and weft woven polyester ribs, which produce extremely high tensile modulus under low strain capacity. The longitudinal and transverse ribs work together to give full play to the interlocking effect of the grid on the soil.
Polyester biaxially stretched welded geogrid is made of longitudinal and transverse polyester ribs woven into a mesh, which has the characteristics of high strength, small elongation at break, and small creep coefficient. The temperature resistance range is from degrees Celsius to degrees Celsius. Anti-ultraviolet and excellent microbial corrosion properties.
Through the treatment of the polyester surface during the production process, rough patterns are pressed to enhance the roughness of the grid surface and improve the friction coefficient between the geogrid and the soil.
The width of polyester biaxially tensile welded geogrid can reach up to 100%, achieving efficient and economical reinforcement effect.
The polyester material used in polyester biaxially tensile welded geogrid can ensure that it will not be corroded by acid, alkali and salt solutions, or oil at normal temperature, and will not be dissolved by water or invaded by microorganisms. At the same time, the polymer properties of polyethylene are sufficient to resist aging caused by ultraviolet radiation. After the grille is stressed, the vertical and horizontal ribs work together to prevent the nodes from being cracked or damaged. In actual projects, after the filler is compacted, it is not corroded by ultraviolet light and oxygen, so it can fully meet the requirements of permanent engineering construction.
Polyester geogrid
Product Application
Can be used in roads, railways, embankments, bridge abutments, construction access roads, wharves, revetments, flood control embankments, dams, tidal flat management, freight yards, slag yards, Civil engineering projects such as airports, sports fields, environmentally friendly buildings, soft soil foundation reinforcement, retaining wall reinforcement, high slope treatment, and water conservancy projects exposed to the outside world.
Features
High strength, small creep, adaptable to various environmental soils, and can fully meet the use of tall retaining walls in high-grade highways.
It can effectively improve the interlocking and interlocking effect of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
Compared with traditional gratings, it has the characteristics of high strength, strong load-bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform holes, convenient construction, and long service life.
It is more suitable for deep-sea operations and embankment reinforcement, and fundamentally solves the technical problems of low strength, poor corrosion resistance, and short service life caused by long-term erosion of seawater by gabions made of other materials.
, can effectively avoid construction damage caused by being crushed and damaged by machinery during the construction process.
Polyester geogrid
Construction method
The paving surface of the geogrid should be relatively flat. After the paving layer is inspected and accepted, in order to prevent longitudinal skew, first lay the paving layer according to the width. Mark the white lines or hanging lines and start laying, and then fix the ends of the grille with type nails (use nail roots for every meter of width and fix them at even distances).
After fixing the ends of the grating, use a laying machine or manual method to slowly pull the grating forward, and manually straighten it once every meter of paving, until one roll of grating is laid, and then lay it down. One roll, the operation is the same as before.
. Continuous paving: The unit of roll length is used as the laying section length. After the section length of the grating should be paved, the overall laying quality should be checked again, and then the next section should be laid.
