Description

Polyethylene one-way stretch geogrid is a high density polyethylene (HDPE) as raw materials, plastics extrusion sheet, punching, heating, stretching. By stretching making the original scattered distribution chain-shaped molecule reorientation and linearly status, the grille sufficiently improved tensile strength and rigidity. It lay in the soil, and by engaging the interlocking effect and soil grid mesh between, constitute an efficient stress transfer mechanism, so that local load quickly and effectively spread to large areas of soil to go, thus helping to lower local failure stress, the purpose of improving the life of the project.
  

Specification

1. Strength :  30KN/M --  300KN/M

2. Width: 1m to 3m

3. Length: As request

4. Loading : 20ft container, 40ft high container  

Advantages  

Polyethylene-way stretch geogrid advantage is sustained in the long term load deformation (creep) the tendency of small, creep strength geogrid is much better than other materials, to improve the life of an important project effect.
The product is suitable for the construction of roads, railways and rivers, lakes and the coast reinforced retaining walls, dams, bridges, steep slopes and Geocell and other projects. Its role is to improve the bearing capacity of retaining walls or dams, extend life and reduce the footprint, shorten the construction period, reduce costs, reduce maintenance costs.

Uniaxial tension geogrid is extruded polymer pressed into sheets and then washed rules mesh, and vertical stretching. This process of linear polymer into the oriented state and the formation of uniform distribution, node strength of the long oval-shaped mesh of high integrity structure. This structure has a very high tensile strength and tensile modulus, especially my company such products more ultra international level high early (elongation at 2% -5%) tensile strength and tensile modulus . The soil provides the ideal force commitment and proliferation of chains. The product tensile strength (> 150Mpa), to adapt to a variety of soil, is widely used in reinforced reinforcement.

Application

Uniaxial geogrid with high strength, widely used in dam, tunnel, port, roads, railways, construction and other fields. 

Its main use is as follows:
1. Enhance roadbed, which can effectively spread of load distribution, improve the stability and foundation bearing capacity and prolong life;
2. Can withstand greater alternating load;
3. Prevent roadbed subgrade material loss caused by the deformation and cracking;
4. Make the filling self-supporting capacity of the retaining wall after the increase, reduce earth pressure retaining wall, save costs, extend life and reduce maintenance costs;
5. The combination of spraying anchor construction method of concrete slope maintenance carried out, not only can save 30% -50% of the investment, but also shorten the construction period more than doubled;
6. Add geogrid in highway roadbed and surface layer, it is possible to reduce deflection and reduce rutting, cracks delayed time 3-9 times the structure thickness can be reduced by 36%;
7. Applicable to all kinds of soil, no off-site coverage, while saving time and labor;
8. simple and quick construction, can greatly reduce the construction cost.
