1) Materials: PP HDPE
2)Width:1-4m
3)Tensile yield per linear mater: 25-260kn/m
stretch plastic geogrid
■Products
Bidirectional polymer geogrid is by extrusion, into a plate, and then punching process vertical and horizontal stretching from. The material in both vertical and horizontal great tensile strength, such a structure in the soil also provide a more effective spread of the force's commitment to the ideals andChain system, adapted to carry a large area of permanent foundation reinforcement.
■Features
1. Increase the road (to) the bearing capacity of the base to extend the road (to) the base of life.
2. Prevention of Road (ground) surface subsidence or cracks, keeping the floor neat appearance.
3. Construction of convenience, saving time, effort, shorten the construction period, reduce maintenance costs.
4. Culverts to prevent cracks.
5. Enhance the soil, prevent soil erosion.
6. Reduce the cushion thickness, saving cost.
7. Support the stability of slopes green grass mat environment.
8. Can replace metal mesh network for coal mine roof off.
■Usage
Two-way stretch plastic geogrid for reinforcement of various dams and embankment, slope protection, wall reinforcement, large airport, parking, terminal freight yard and other permanent foundation bearing reinforcement.

■Product specifications and performance parameters
The use of the finite element method two-way bridge geogrid reinforced embankment to control Bump of issues. Spacing on the bridge of reinforced embankment settlement, the vertical distribution of additional stress, the geogrid tensile stress and strain were investigated. The results show that a reasonable solution for the reinforcement of the bridge embankment treatment can effectively control the bridge embankment settlement, and makes the bridge abutment and the embankment settlement to smooth the transition between, for the control of creating favorable conditions for Bump.
Applications
1 A variety of roads, railways, airports subgrade enhancement;
2 Large parking lot and terminal freight yard and other permanent foundation bearing enhancement;
3 Rail, road slope protection, culvert enhancement;
4 Uniaxial geogrid enhance soil after the second increase, and further enhance soil, preventing soil erosion;
5 Mining, tunnel reinforcement.
Construction Method
Excavation of foundation bed, set the sand cushion(Height less than 10cm), rolled into the platform, laying grille, the vertical axis to be the major force in the same direction with the longitudinal lap 15-20cm, horizontal 10cm, lap belt with plastic banding, and in laying the grill, every 1.5-2m with U-nails on the ground, laying the geogrid should be promptly backfill material, laying the geogrid layers as the technical requirements.
Requirements of the construction process of 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 white line drawn in the pavement layers or hung, you can begin paving, and then iron Nail the ends of grid (each 8 m wide with a nail, even from fixed).

After the end of fixed grid, the grid with a paving machine shop pull slowly 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 after a roll of the roller with the 6T-10T began to move from a starting point to the direction of rolling over. (Such as paving in the surface layer and the leveling layer, the steel roller roller appropriate; such as grid laid directly on concrete pavement, and with the rubber roller roller appropriate.)

Then shop: A unit of volume as long as the laying of the section chief, shop in the grid should be covered within the section chief then, once again paving the overall quality check, and then followed by laying of the next paragraph. Paving the next section, the grille and grille can be 10-15CM length of the lap, and fixed with a nail or wedge the way forward to continue to shop after the second paragraph. And so on, operational requirements with the former.
