Way plastic geogrid Products: two-way stretch plastic geogrid ■ Introduction bi polymer geogrid is by extrusion, into a plate, then punching process vertical and horizontal stretching from. And assume an ideal diffusion of the material of the chain system in the vertical and horizontal great tensile strength, such a structure in the soil also provide a more effective force, is adapted to carry a large permanent in foundation reinforcement. ■ Features 1. Increase the bearing capacity of the road (to) the base to extend the road (to) the base of life. 2. Prevent Road (ground) surface subsidence or cracks, keeping the floor neat appearance. 3. Construction of convenience, saving time, effort, shorten the construction period and reduce maintenance costs. 4. Culverts to prevent cracks. 5. Enhance the soil, prevent soil erosion. 6. Reduce the cushion thickness, saving cost. 7. Net supporting slope stability mat grass green environment. 8. Can replace metal mesh network for coal mine roof. ■ Uses two-way stretch plastic geogrid for various dams and embankment, slope protection, wall reinforcement, ground reinforcement large airport, parking, terminal freight yard and other permanent bearer. ■ Product specifications and performance parameters using the finite element method to use two-way geogrid reinforced embankment bridge to control the Bridgehead Bump study the issue. Analysis of reinforced layer spacing of the bridge embankment settlement, vertical additional stress distribution, influence of tensile stress and strain of the geogrid. The results show that a reasonable plan to make the bridge embankment reinforced handle, can effectively control the bridge embankment settlement, and make settlement between the abutment and embankment can smooth transition, for the control of the bridge to create favorable conditions for jumping. Applications 1, all kinds of roads, railways, airports roadbed enhancement; permanent foundation bearing two large parking lot and dock yard, such as enhanced; 3, slope protection railways, roads, culverts enhancement; 4-way stretch Second slope geogrid reinforced enhanced further enhance the soil, prevent soil erosion; 5, mining, tunnel reinforcement. Foundation bed excavation construction method, 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, transverse 10cm, ride take place with plastic tape binding, and the laying of the grille, every 1.5-2m with U-nails on the ground, laying geogrid shall promptly backfill material, laying geogrid layers, as 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 the width of the pavement layer draw a white line or thread, 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 grill, grill with a paving machine shop slowly pulled forward, each 10 meters long shop 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 the 6T-10T. (Such as paving on the surface layer and the leveling layer, steel roller compactor is appropriate; if the grid laid directly on the concrete pavement with a rubber roller roller appropriate.) Then shop: to roll as long as the unit laying section chief, section chief in the future shall be covered within a covered grill, check once again the overall quality paving, paving and then the next paragraph. The next section of paving, grille and grille can 10-15CM lap length and continues to pave the way forward after the second paragraph with nails or wedge fixed. And so on, with the former operating requirements
