This product is mainly used for securing the sides (ribs) of workings in underground coal mining. It is used as a fastening material for various types of mines, including anchored, frame-supported and shotcrete-supported excavations. When used as an artificial roof, several layers are used to strengthen the structure.
polyester geogrids
High strength, low creep and adaptability to various soil types make it fully suitable for use in high retaining walls on high-class highways.
Effectively enhances the adhesion and cohesion of the reinforced bearing surface, significantly increasing the bearing capacity of the foundation, effectively limiting lateral soil displacement and improving the stability of the foundation.
Compared with traditional geogrids, it has higher strength and load-bearing capacity, better corrosion and weather resistance, aging resistance, high friction coefficient, uniform cell distribution, ease of installation and a longer service life.
It is particularly suitable for deep-sea work and embankment reinforcement, fundamentally solving the technical problems of other materials used in gabions, such as low strength, poor corrosion resistance and short service life caused by long-term exposure to seawater.
Effectively prevents damage during construction caused by crushing or destruction of material by construction equipment during installation.
Product Details
Geogrid is a basic geosynthetic material that has unique properties and functions compared to other geosynthetics. It is widely used as a reinforcing element in reinforced soil structures or as reinforcement in composite materials. Geogrids are divided into four main categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids and warp knitted polyester geogrids.
Geogrids are two-dimensional mesh structures or three-dimensional lattice screens with a certain height, formed by thermoplastic molding or injection molding from high molecular weight polymers such as polypropylene and polyvinyl chloride. When used in civil engineering work, they are called geogrids.
Polymer mesh materials formed by drawing into square or rectangular cells, depending on the direction of drawing during the production process, are divided into uniaxial and biaxial. They are made by punching holes in extruded polymer sheets (usually polypropylene or high-density polyethylene) and then oriented drawing under heat. Uniaxial geogrids are stretched only along the length of the sheet, while biaxially oriented geogrids are obtained by additional stretching of a uniaxial geogrid in a direction perpendicular to its length.
During the production process, polymer macromolecules in plastic geogrids are redistributed and oriented under the influence of heat and stretching, which strengthens intermolecular bonds and increases the overall strength of the material. Their relative elongation is only 10–15% of the elongation of the original sheet material. The addition of anti-aging components, such as carbon black, to geogrids provides high durability, including resistance to acids, alkalis, corrosion and aging.
Product Features:
High strength, minimal deformation;
Low creep;
Corrosion resistance and long service life:
Steel-plastic geogrids have a plastic protective layer with the addition of various anti-aging and antioxidant additives, which provides resistance to corrosion in aggressive environments such as acids, alkalis and salts. This enables them to meet service life requirements of over 100 years in a variety of permanent engineering structures, demonstrating excellent performance and dimensional stability.Quick and easy installation, short construction cycle, low cost:
Steel-plastic geogrids are easily laid, overlapped and fixed, providing a smooth and neat surface. Eliminating the need for complex overlaps and intersections effectively reduces project implementation time and reduces construction costs by 10–50%.
Polyester Warp Knitted Geogrid
Polyester warp-knit geogrids are made from high-strength polyester fibers. Thanks to the use of an oriented warp-knitted structure, the warp and weft threads in the fabric have no bends. The intersection nodes are connected by high-strength filament threads, forming strong connecting points, which allows their mechanical properties to be fully realized.
Warp-knit geogrids made from high-strength polyester fibers are characterized by high tensile strength, low elongation, high tear resistance, minimal difference in strength in the longitudinal and transverse directions, and resistance to ultraviolet aging, abrasion and corrosion. The material is lightweight and provides strong adhesion to soil or crushed stone. Such geogrids effectively increase the shear strength of the soil, enhance its integrity and significantly increase the bearing capacity.
Biaxially oriented plastic geogrid
Suitable for reinforcing various embankments and road bases, strengthening slopes, strengthening tunnel walls, as well as for reinforcing the foundations of permanent load-bearing structures such as large airports, parking lots, and port cargo areas.
Characteristics of biaxially oriented plastic geogrid:
Increases the load-bearing capacity of road bases and foundations, extending their service life.
Prevents subsidence and cracking of the surface, ensuring a neat and aesthetic appearance.
Provides ease of construction, saves time and labor resources, reduces project implementation time and reduces maintenance costs.
Prevents cracks in culverts.
Strengthens earth slopes and prevents soil erosion.
Allows to reduce the thickness of the roadbed, reducing construction costs.
Provides stability to grass mats for slope landscaping and environmental improvement.
Can replace metal mesh when used as artificial roofing mesh in coal mines.
Applications
Suitable for reinforcing roadbeds and strengthening road surfaces on highways, railways and airports.
Suitable for strengthening the foundations of permanent load-bearing structures such as large car parks and port cargo areas.
Suitable for strengthening slopes on railways and roads.
Suitable for reinforcing culverts.
Suitable for secondary reinforcement of slopes already reinforced with uniaxial geogrids, further increasing slope stability and preventing soil erosion.
Suitable for reinforcement in mine workings and tunnels.
