The company is a large comprehensive enterprise known domestic production of geosynthetics and import and export enterprises specialized in the production, research and development of geosynthetics and new composite materials. Mainly produces operating YN crack control paste, crack paste way geogrid way geogrid, fiberglass geogrid, warp knitting geogrid, steel plastic geogrid, mining geogrid 3D geonet mat, high strength geonet, geocell, engineering fiber, plastic blind ditch, soft water pipe, short wire geotextile, filament geotextile, geomembrane, composite geomembrane and other engineering materials. Its products are mainly used in the aerospace, aviation, military, chemical, oil; roads, railways, coal mining, water conservancy, electric power, water and soil conservation, and environmental greening and infrastructure areas, has been widely used in a number of national key projects such as highways, railways . The way plastic grille polymers by squeezing into boards, punching process after longitudinal, transverse stretching. The appearance of the biaxially stretched plastic geogrid approximately square network structure, it is with the polypropylene as the main raw material by extrusion, and then longitudinal, transverse stretch formed of a high strength geotextile material. This material has great tensile strength in the longitudinal and transverse direction, are widely used in soft Foundation ribs. The material in the longitudinal and transverse directions have a great tensile strength, this structure in the soil also can provide a more effective force bears and ideal for the proliferation of the chain system, adapted to large area permanent bearer foundation reinforcement. With heating extension process, due to the way plastic geogrid in the manufacture of the polymer in polymer rearrange directed to strengthen the links between the molecular chains force, to achieve the purpose of improving its strength. Its elongation of only 10% of the original sheet material to 15%. Geogrid anti-aging material such as carbon black, it has good acid and alkali resistance, anti-corrosion and anti-aging durability. Way plastic geogrid production process: the way plastic geogrid for raw materials (PE) polyethylene additive particles after hot melt after the formation of the board and then punching the formation of a two-way plastic geogrid. Range of applications: two-way stretch plastic geogrid applicable the permanent foundation reinforcement hosted at various dams and embankment reinforcement, slope protection, wall reinforcement, large airport, parking lot, pier freight yard. 1, all kinds of roads, railways, airports subgrade enhancement; 2, large car park and pier freight yard permanently hosted ground-based augmentation; 3, slope protection of railways, highways, culverts and enhancement; 4, one-way stretch Geocell enhanced the soil slopes secondary gate enhanced further enhance soil slopes to prevent soil erosion;, mining, tunnel reinforcement. Product Features: 1. Increase the carrying capacity of the road (ground) base to extend the service life of the base of the road (ground). 2. Prevent surface subsidence or cracks Road (ground), keep the ground neat appearance. Construction, saving time, effort and shorten the duration and reduce maintenance costs. 4 to prevent the culvert cracks. 5. Enhance soil slopes to prevent soil erosion. 6. Cushion thickness reduction and cost savings. 7 support slope grass mat stability of a green environment. 8. Replace metal mesh for the network of off the top of the coal mine. Require geogrid geogrid construction technology paved surface should be relatively flat, paved layer inspected and accepted, in order to prevent vertical skew phenomenon, press width in paving layer draw a white line or hang up, you can end of the paving, and then fixed with nails grille portion (8 meters wide with nails, the uniform distance is fixed). After the end of the fixed grille, pavers will grill slowly pulled forward shop, every shop 10 meters long artificial taut and straightening up a roll of grille Puwan holes under roll operation with the former. Puwan roll after 6T-10T road roller from the start point to the forward direction of rolling again. In the surface layer and the leveling layer (such as paving steel roller compactor appropriate; such as the grille laid directly on the concrete pavement with a rubber roller compactor is appropriate.) Then shop: roll length as laying segment length, segment length should shop grille covered, and then check the quality of the time paved as a whole, and then followed by paving the next paragraph. Next paragraph paved, grille and grille with a lap length of 10-15CM, fixed with nails or wooden wedges continue forward direction Shop the second paragraph. And so on, operating requirements with the former excavation foundation bed, set the sand cushion (height difference of not more than 10cm), rolled into the platform, laying grille, to the vertical axis should be consistent with the main direction of the force, longitudinal lap 15 -20cm, horizontal 10cm, plastic with lap banding, and laying on the grille, every 1.5-2m with a U-shaped nails fixed on the ground, laying the geogrid should be back in time to fill material, laying Geocell gate layers depending on technical requirements. Geogrid construction points: 1, construction site: requirements compaction flat, horizontal shape, clear spikes protuberance. 2, the laying of: the formation compaction venue, the installation grille laying the grille its mainly affected by the force direction (vertical) should be perpendicular to the the embankment axis direction, laying to be smooth, wrinkle-free, try tension. Pressure re-nailing and quarrying fixed laying grille is mainly affected by the direction of the force through long connector, the connections between the pieces and the pieces can be manually banding lap, lap width of not less than 10cm. Such as setting the grid in two or more layers between layers should be staggered joint. After the laying of the large area to adjust its overall flatness. Fill cover layer of soil, not compacted again with artificial or machinery tension grille, the intensity should be uniform, the grid in the soil for Bengzhi force status. 3, the choice of filler: filler should design requirements selected. Practice has proved that can be used in addition to freezing soil, swamp soil, garbage, chalk, diatomaceous earth filler. However, the Gravel soil and sandy soil stability, mechanical properties and by the water content has little effect, should be preferred. Filler particle size of not more than 15cm, and pay attention to controlling the the filler gradation, in order to ensure the weight of the compaction. Persistent hosted foundations. Remarks special specifications and requirements of the contract or agreement with the finite element method to study the problem of the use of two-way geogrid reinforced the bridgehead embankment, which control Bump. The analysis reinforced layer spacing vertical additional stress distribution, settlement bridgehead embankment, the influence of the geogrid tensile stress and strain. The results show that the bridgehead embankment the reinforced treatment, can effectively control the bridgehead embankment settlement, and bridge abutment embankment settlement can smooth the transition, and created favorable conditions for the control of the Bump reasonable solutions.
