High-density polyethylene Uni-axial geogrid
Introduction
High-density polyethylene Uni-axial geogrid is based on raw material as HDPE, after a plastics extrusion, sheet metal punching, vertical stretching of a high-strength reinforcement geosynthetics. Be laid in the soil, through the mesh of the grid and interlock soil occlusion and the role of stress constitutes an efficient transmission mechanism is local and can be quickly and effectively in the spread to large areas of soil, Thereby reducing the local stress damage, increase the life of construction.
Performance
Uni-axial geogrid with high-density polyethylene has high creep strength and good durability, from the soil of harmful substances (such as acid, alkali, salt and other chemical substances) and non-biological erosion, in the case of vegetation or soil cover, the service life of up to 120 years.
Applications
Mainly used in the construction of roads, railways and rivers coast reinforced earth retaining wall, dam, bridge, steep slopes and other slope protection works. Its prominent advantage is the long-term continuous deformation under load (creep) tend to small, to improve the life of the building has an important role.
