Introduction

PP plastics uniaxial geogrid is made of high molecular polymer, which is plasticized and extruded, punched, heated and then stretched longitudinally.It has extremely high tensile strength and tensile modulus.PP Uniaxial plastic geogrid is suitable for construction of railways, highways, bridge abutments, port terminals, retaining walls, dam reinforcement, slope reinforcement and other projects, which can greatly improve the bearing capacity, prolong the service life and reduce the floor space. The construction is convenient, the construction period is shortened, the cost is reduced, and the maintenance cost is greatly reduced.

Function

1. Uniaxial geogrid is a kind of high-strength structural materials for highways, municipal roads, railways and other subgrade enhancement;

2. It is applied in the enhancement of dam rivers and the sea dike;

3. It is applied in the fence of orchards, vegetable, livestock, land, et. The use is safe and convenient, and conducive to disassembly, elegant appearance;

4. It is applied in the earth retaining and wall reinforcement works of highways, municipal roads, railways, rivers and along the coast;

5. It is mainly used for retaining walls, abutment, slope works and so on;

6. Retaining walls and abutment are force structure which assume all external load, the active earth pressure, the upper part of the structure of the dynamic load, temperature stress and so on, in a larger long term reinforcement under tension, as well as the effect of repeated dynamic loading, the molecular structure of materials fatigue, occurred in the performance of attenuation and speed up the aging grid. In order to avoid deformation resulting from reinforcement material creep, it is better to select a high-density polyethylene(HDPE) as raw materials for uniaxial geogrid.
