Polyester Geogrid

2019-10-28

geogrid definition: two-dimensional grid or a certain height of three-dimensional grid with thermoplastic or molded polymer such as polypropylene or polyvinyl chloride The screen grid, when used as a civil engineering, is called a geogrid.
1. Geogrid Geogrid is a major geosynthetic material with unique properties and efficacy compared to other geosynthetics. Geogrids are often used as reinforcements for reinforced earth structures or as composite materials. Geogrid is divided into four categories: plastic geogrid, steel geogrid, fiberglass geogrid and glass fiber geogrid.
(1) Plastic geogrid The plastic geogrid is a square or rectangular polymer mesh which is formed by stretching, and may be uniaxially stretched or biaxially stretched according to the direction of stretching in the manufacture. It is punched on a extruded polymer sheet (mostly polypropylene or high density polyethylene) and then subjected to oriented stretching under heating. The unidirectionally stretched grid is stretched only along the length of the sheet, while the biaxially stretched grid is continuously stretched by stretching the unidirectionally stretched grid in a direction perpendicular to its length.
Since the polymer of the geogrid in the manufacturing process is rearranged and oriented with the heating extension process, the bonding force between the molecular chains is strengthened, and the strength is improved. Its elongation is only 10% to 15% of the original board. If an anti-aging material such as carbon black is added to the geogrid, it can have good durability against acid, alkali, corrosion and aging.
(2) Steel-plastic geogrid steel-plastic geogrid with high-strength steel wire (or other fiber), specially treated, with polyethylene (PE), and other additives, through extrusion to make it a composite high-strength tensile Strips with rough embossing on the surface are high-strength reinforced geotechnical belts. The single belt is formed by longitudinal or transverse arranging or clamping, and is welded by a fusion welding technique with special strengthening bonding to form a reinforced geogrid.
(3) Glass fiber geogrid Glass fiber geogrid is a mesh structure material made of glass fiber and made by a certain weaving process. It protects the glass fiber and improves the overall performance. After special coating process Geosynthetics. The main component of glass fiber is: silicon oxide, which is an inorganic material. Its physical and chemical properties are extremely stable, and it has high strength, high modulus, high wear resistance and excellent cold resistance, no long-term creep; thermal stability. Good property; the mesh structure makes the aggregate interlock and limit; improve the load-bearing capacity of the asphalt mixture. Because the surface is coated with special modified asphalt, it has two-fold composite performance, which greatly improves the wear resistance and shearing capacity of the geogrid.
Sometimes combined with self-adhesive pressure-sensitive adhesive and surface asphalt impregnation, the grid and asphalt pavement are tightly integrated into one. Due to the increased interlocking force of the earth and stone in the geogrid grid, the friction coefficient between them increases significantly (up to 08 to 10), and the pull-out force of the geogrid embedded in the soil is due to the gap between the grid and the soil. The frictional bite force is stronger and significantly increased, so it is a good reinforcement material. At the same time, the geogrid is a kind of plastic flat net material with light weight and certain flexibility. It is easy to cut and connect on site, and can also overlap and overlap. It is easy to construct and does not require special construction machinery and professional technicians.
(4) Polyester fiber warp-knitted geogrid Polyester fiber warp-knitted geogrid is selected from high-strength polyester fiber. The warp-knitted oriented structure, the warp and weft yarns in the fabric are not bent with each other, and the intersections are combined with high-strength fiber filaments to form a firm joint point, giving full play to its mechanical properties, high-strength polyester fiber warp-knitted geogrid The grid has high tensile strength, small elongation force, high tear strength, small difference in longitudinal and transverse strength, resistance to ultraviolet aging, abrasion resistance, corrosion resistance, light weight, strong interlocking force with soil or gravel, and reinforcement of soil. Shearing and reinforcing improve the integrity and load of the soil and have a significant effect.
