Introduction

Uniaxial polyethylene geogrid uses high density polyethylene(HDPE) as raw material. It is plasticsed, sheet extrused, punched, heated and stretched. In this process macromolecule is orientated into a linear state and long oval-shaped high overall network structure. Through the stretching, it makes the original distribution of the chain-shaped molecules scattered reorientation and linear, which fully improved tensile strength and rigidity of the grille. Laying in the soil, through the mesh grile and soil and the interlocking between the role if occlusion constitute an efficient stress tranfer agencies, so that the local load can be quickly and effectively spread to a large area of soil, and in order to achieve lower local failure stress, to achieve the purpose of improving life.

This kind of products in our company have such an international stardard ultra-high early(at 2% elongation-5%)tensile strength and tensile modulus, the soil provides the ideal power to bear and spread of the chain system. The tensile strength is high(>150Mpa)so that it is a kind of reinforcee material that can be used in all sorts of soils.

Features

Polyethlene uniaxial geogrid's prominet advantage is the tendency of deformation under the long-term sustained load(creep) is small and anti-creep strength is much better than other geogrid material, which play an important project role in improving the life.

The product is applied in the construction of roads, railways and rivers, lakes and along the coast of the reinforced retaining wall, dam, bridge, steep slopes and other projects geocell. Its role is to enhance the profile of the bearing capacity of the dam wall or to extend the servicelife, reduce the area and shorten the construction period, lower costs and reduce maintenance costs.

Function

Uniaxial geogrid is kind of high strength geosynthetic. It has extensive applications in dyke, tunnel, pier, highway, railway and building.

Its main applications are as follows:
1. Enhance roadbed and effectively diffuse its load to improve its stability and bearing capacity and increase service life;
2. Can bear more alternate load;
3. Prevent roadbed distortion and crack caused by the loss of roadbed materials;
4. Increase the self-supporting property of fill behind retaining wall, decrease the earth pressure of retaining wall, save cost, increase service life and reduce maintenance expense;
5. Combine anchor sprouting concrete construction method to give side slope maintenance, which not only saves investment by 30%-50% but also reduces erection time by one time or above.
6. To increase geogrid in the roadbed and surface of highways can reduce flexure, track and put off the flawing appearance by 3-9 folds and reduce the thickness of structural layer by 36%;
