Best plastic geogrid lowest price and best quality way grille

 Product Description: Product Name: two-way plastic geogrid Products: two-way stretch plastic geogrid network-like structure approximate the appearance of the square, which is the main raw material of polypropylene by extrusion, and then vertical and horizontal stretching the formation of a high-strength geotextile material. The material on the vertical and horizontal great tensile strength, is widely used in soft foundation reinforcement treatment. Applications: 1, applies to all kinds of roads, railways, airports roadbed reinforced surface enhanced. 2, the foundation for large parking lot and terminal freight yard and other permanent bearer enhanced. 3, for slope protection railways and roads. 4, for a culvert enhancement. 5 for a one-way stretch geogrid reinforced slope after secondary enhanced further enhance the soil, prevent soil erosion. 6, mining, tunnel reinforcement.

Analysis of reinforced layer spacing of the bridge embankment settlement, vertical additional stress distribution, the influence of tensile stress and strain of the geogrid. The results show that a reasonable program for the reinforcement of the bridge embankment treatment can effectively control the bridge embankment settlement, and make settlement between the abutment and embankment can smooth the transition for the control of the Bridgehead Bump created favorable conditions. Applications 1, all kinds of roads, railways, airports roadbed enhancement; permanent load bearing foundation 2, large car park and terminal freight yard and other enhancements; 3, slope protection railways, roads, culverts enhancement; 4-way stretch Second slope geogrid reinforcement enhanced to further enhance the soil, prevent soil erosion; 5, mining, tunnel reinforcement. Construction method excavation foundation bed, set the sand cushion (height of not more than 10cm), rolled into the platform, laying grille, the vertical axis to be consistent with the direction of the main force, longitudinal lap 15-20cm, lateral 10cm, take Point for banding with plastic tape, and the laying of the grid, every 1.5-2m with U-nails on the ground, laying geogrid should be promptly backfill material, laying geogrid layers depending on the technical requirements. Construction technology requirements geogrid Geogrid paved surface should be relatively smooth, paving layer after passing the acceptance, in order to prevent the phenomenon of vertical skew, press width white line drawn in the pavement layers or hung, you can begin paving, and then fixed with nails grille ends (each 8 meters wide with a nail, uniform distance fixed). After fixing the ends of the grid, with a paving machine to pull forward slowly grill shop, shop 10 meters long each manual tensioning and straightening time, until the volume grid Puwan, holes and under the roll, operation with the former. Puwan roll began rolling it again in the forward direction from the starting point of the roller with 6T-10T. (Such as paving on the surface layer and the screed, steel roller roller appropriate; such a grid laid directly on the concrete pavement, with a rubber roller roller appropriate.) Then shop: a roll as long as the unit laying section chief, section chief in the future shall be covered within a covered grill, 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 move forward with the direction of the second paragraph after the nail shop or wedge fixed. And so on, with the former operating requirements. Geonet, geogrid A. on the road is mainly used for soft ground treatment, roadbed enhancement, slope protection, reinforcement abutment, (1) soft ground wing walls, retaining walls, reinforced earth isolation and folders in road projects the laying of geonet or geogrid can improve the subgrade bearing capacity, long life, prevent pavement cracks; (2) the laying of geotextile nets on the road slope to prevent landslides, and soil and water conservation, landscaping; (3) paved highway bridge abutment foundation geonet or geogrid can increase the carrying capacity, stable abutment to prevent cracking bridges, and avoid jumping; (4) geonet or geogrid soil reinforcement for folders wing wall , panel thin, small base size, can save a lot of earth, reduce costs; (5) the use of geotextile mesh or geogrid in highway retaining wall, it can increase the carrying capacity of retaining wall to prevent landslides, and can save a lot of earth, a substantial reduce the construction period and reduce the project cost; (6) geonet or geogrid used as surface enhanced, can spread the load effectively prevent pavement cracks; B. use geonet or geogrid on the railway on soft soil can be avoided Railway premature settlement produced and destroyed (1) laying geogrid Geo network or the railway embankment, and they were with the road material more rigid foundation, which can effectively allocate load, preventing roadbed deformation and improve its stability; ( 2) the laying of the railway slope geotextile mesh to prevent rock fall, causing harm to the person or vehicle to maintain railway flow; (3) geonet or geogrid wrap ballast to prevent the loss of ballast and subgrade deformation to improve its stability (4) the use of geotextile mesh or geogrid reinforced steep increase clip a railway line, just add little or no additional area; (5) the use of railway retaining wall geonet or geogrid retaining wall can enhance the carrying capacity, prolong life (6) geonet or geogrid in the subway tunnel to improve the structural strength of the tunnel, to prevent landslides C. geonet or geogrid also be applied - embankment dam, river, canal, reclamation dike, reservoir reinforcement other water conservancy projects (1) the laying of geotextile on the slope of the reservoir or river can prevent soil erosion caused by loss of water; and (2) Reservoir dam or reservoir bottom end of the laying of geotextile or geogrid prevents the base of the dam sedimentation occurs; (3) the geotextile net cage made of stone can be reinforced reservoirs, rivers or coastal slope to prevent water erosion, stone cage Shen bed to avoid underwater operations; (4) reservoir project geonet or geogrid use to set the vertical retaining wall, reducing the land, but also to increase the storage capacity; D. geonet or geogrid reinforced foundation airport runway can greatly improve the carrying capacity to ensure that aircraft movements Security E. geonet or geogrid can be used to refuse site treatment plant ash dam construction, mining, metallurgy, green, pens, and other areas of (1) the laying of geonet or geogrid slope coal mine iron on track Pulverized coal or prevents slipping on the rails, the impact of coal cars run; (2) geonet do mine off the top, you can improve the structural strength of mine, to prevent landslides and ensure the safety of miners; (3) In some special places, laying temporary access can be laid directly on a layer of geotextile mesh or geogrid, cars will be able to smooth passage, convenient and fast; can save construction costs; (4) fence made of geonet or geogrid will slag heaps in the fence, both beautiful and easy to work there, but also reduce the area; (5) geonet or geogrid can be used to handle garbage site. Either to prevent environmental pollution, but also reduce the area, and contribute to refuse storage; (6) Geo network can also be used for simple protective isolation, fence project. (7) Geo network folder tendons ramp built surface shape desired. (8) The geotextile can be applied to the thermal power plant ash dam project, to prevent sedimentation and reduce pollution.
