Way plastic geogrid is a polymer mesh material with a square or rectangular form after stretching, stretch and different way stretch stretching direction when its two manufacturing as unidirectional. It was punched in by squeezing out the polymer sheet (mostly raw materials, polypropylene or high density polyethylene), then the purposes of orientation stretch under heating conditions. Stretching the uniaxially stretched grid is made only along the longitudinal direction of the sheet, while the biaxial stretching is continued to the grill grid and then uniaxially stretched in a stretching direction perpendicular to its length is made. As the plastic in the manufacture of polymer geogrid polymer will rearrange the orientation process with the heating extend and strengthen the bonding force between the molecular chains, to improve its intensity. Its elongation of only 10% to 15% of the original plate. If the addition of carbon black and other anti-aging material geogrid, you can make a good acid and alkali resistance, corrosion resistance and anti-aging durability has. First, what is plastic geogrid: plastic geogrid is a polypropylene (PP) or polyethylene (PE) as raw materials, plastics sheet extrusion, punching, heating, stretching the longitudinal and transverse stretching . Second, the plastic geogrid What features: plastic geogrid in the longitudinal and transverse have great tensile strength, such a structure in the soil can provide a more effective force to bear and spread the ideals chains , adapted to carry a large permanent foundation reinforcement of. Third, plastic geogrid engineering applications: for foundation reinforcement of various dams and embankment, slope protection, wall reinforcement, large airports, car parks, piers and other permanent bearer yard. 1.

Plastic geogrid ?? construction process: paved surface of the plastic geogrid should be relatively smooth, paving layer after passing through closing, to prevent longitudinal tilt, press the width of the pavement layer draw a white line or thread , you can start paving, then the ends of nails fixed plastic geogrid (each 8 meters wide with a nail, the average interval fixed) use. After fixing the ends of the plastic geogrid, with a paving machine will pull forward slowly plastic geogrid shop, shop 10 meters per Offer artificial tension and straightening time, until the roll of plastic geogrid Puwan, holes and under the roll, with the former operation. Puwan roll it again after rolling the roller with 6T-10T start from the starting point to the direction of travel. (Eg, on the surface layer of paving screed and on, steel roller compactor is appropriate; such as grid laid directly on the concrete pavement with a rubber roller compactor is appropriate.) Plastic geogrid then shop: to roll long? As long as the unit paved section, shall be covered in plastic geogrid after long segment within covered, check once again paving the overall quality, and then paved the next paragraph. The next section of paving, grille and grille can use the lap length 10-15CM and continue to the travel direction of the shop after the second paragraph with nails or wedge fixed. And so on, the operation request with the former. Plastic geogrid Product Features:?. A carrying capacity increases road (to) the base to extend the use life of the road (to) group. 2. Avoid Road (ground) surface subsidence or cracks, adhere to the air and beautiful uniform. 3. Construction lunch, saving time, effort, shorten the construction period and reduce maintenance costs. 4. Avoid culvert cracks. 5. Strengthening slopes, avoid soil erosion. 6.

Geotextile material is widely used today in geotechnical engineering geosynthetics, it is a polymer products collectively. Back in the 1920s, the chemical sector that is successfully produced synthetic materials, but until the late 1950s, this material is only gradually, as a new building material has been extended to the geotechnical engineering. Early products are mainly permeable woven and nonwoven geotextiles, and later produced impermeable geomembrane. With the practice of engineering requirements and improve the manufacturing process, but also have to create a geogrid reinforced with high-strength and other combination products. Thus, the original term of geotextile fabric has been far can not summarize the meaning of various products, so there are many alternative names in the international arena, the term geotextile material of which the most common, but still customary system called geotextile. Materials geotextile material divided into several categories: geotextiles, geomembranes, geogrids, drainage board, geomembrane, geotextile, Geocell, waterproof blanket. Wherein the glass fiber geogrid is a new kind of superior geotextile substrate pavement and subgrade enhancement products to E-glass fiber filaments as the main raw material, made by weaving a unique weaving process, with a special rubber coating from mesh structural material. Can effectively improve the structural stress distribution road, resist and delay the occurrence of reflective cracking due to cracks caused by the grassroots, to improve the life of the road, and can reduce the cost and improve the quality of construction. The product is the company introduced a new patented product, the use of glass fiber geogrid adhesive coating treatment from the self-inductance, while maintaining fiberglass geogrid features and functions on the grill and the contact surface so closely together, with easy construction, paving leveling characteristics, especially for road construction, road reinforcement, the old road reconstruction and other projects Reinforcement. Composite geotextile is made of high-strength glass fiber or polyester fiber yarn and nonwoven fabrics were made by weaving or bonding geotextile made of new composite materials, organic combination of glass fibers and nonwoven fabrics both excellent performance, with the exception geogrid has high strength, low elongation, high elastic modulus, temperature and other characteristics, but also has good anti-infiltration and filtration capacity, is a versatile geosynthetics, can effectively extend the project to use life, reduce maintenance frequency, reduce project cost for enhanced and reinforced isolation protection embankment road pavement, irrigation dams and other projects. High-strength polyester geogrid is a new high-quality reinforced embankment geotextile substrate, using high-strength polyester fiber or polypropylene fiber as raw material, weaving through the warp direction, with a special coating treatment from dipping. Has a very high tensile strength, low elongation, subgrade engineering can effectively prevent surface cracking and improve the carrying capacity of soft soil to prevent foundation settlement, reduce project cost, improve construction efficiency, thereby improving roads, railways such as the use and quality of life of the project. Huayi plastic grille in production and strict quality requirements Huayi geotextile material products of high level of production technology, production, good performance, complete specifications, the majority of customers get a high rating, giving users the construction or production units job brought great convenience, and fully guarantee the quality of high-quality geotextile material. The total area of ??plastic geogrid ribs smaller than its open area as possible, in order to ensure the mechanical interlocking engagement with a relatively large effect, that is to say as much as possible to make the mesh more bite soil area in order to give full play to its occlusion effect, but the mesh size should not be too large, otherwise the rib stiffness smaller, bite force has actually helped reduce. Plastic geogrid ribs and rib to be perpendicular to each other, in order to more effectively transfer loads. If they are not vertical, will reduce the effect of load transfer, leaving the reinforcement effect is poor. This pseudo-grid (such as the preparation of composite welded) are different. Pseudo-grid nodes are woven or welded composite, holistic difference, vertical and horizontal transfer exercise can be poor. At present, our factory workers of one mind, improve the comprehensive internal mechanisms, at present, our factory workers of one mind, improve the comprehensive internal mechanism, fully activated fighting spirit, to further expand domestic and foreign plastic geogrid product markets, the development of production for the majority of users and make a greater contribution to economic prosperity. Huayi provide resistance to low temperature geogrid very popular tradition, especially high embankment embankment embankment often require super easy to fill and compaction shoulder edge, causing flooding hit late slope of rain, the collapse instability phenomena have occurred , while the need to use more moderate slope, large area, retaining walls also have the same problem, the use of geogrid reinforced embankment slope or retaining walls can reduce half a footprint, long life, low cost of 20-50%. Geogrid soil combined with other synthetic materials handling landfill, can effectively solve the uneven foundation settlement, derived gas emissions and other issues, and can maximize storage capacity landfill.
