Unidirectional plastic technical grid is a kind of technical material with high strength that uses high molecular polymer as main raw material, adds certain ultraviolet proof and aging resistance agent and makes messy chain shape molecules have directional layout and from linear status by unidirectional extension.
Plastic technical grid makes directional tension under certain temperature condition according to physical features of high molecule polymer, so its strength is very high in tension direction, tension resistance reaches 100-200Mpa, yield elongation rate is only 4-10%, it is near to the level of low carbon steel and much better than traditional or current reinforcement materials, and is very ideal synthetic material for strengthening and reinforcement of civil projects.
Feature:
1. High unidirectional tension resistance, good creep resistance and stable chemical nature.
2. It has large friction factor with sandy stone.
Application:
Unidirectional geogrid is used to support vulnerable foundations: geogrid can shortly enhance the bearing ability of the foundation, manage the improvement of settlement, and efficaciously distribute the load on a wider sub base layer due to its lateral limiting impact on the street base layer, thereby lowering the thickness of the base layer, decreasing engineering costs, shortening the development period, and extending the carrier life.
2. Unidirectional geogrid is used for strengthened asphalt or cement pavement: geogrid is laid at the backside of the asphalt or cement pavement layer, which can limit the depth of ruts, lengthen the fatigue existence of the pavement, and additionally minimize the thickness of asphalt or cement pavement to retailer costs.
3. Unidirectional geogrid is used to support embankment slopes and maintaining walls: Traditional embankments, specially excessive embankments, frequently require overfilling and the part of the shoulder is now not effortless to compact, ensuing in the prevalence of slope rainwater infiltration and fall down instability in the later stage. At the equal time, slower slopes are required, occupying a massive area, and conserving partitions additionally have the equal problem. Using geogrids to strengthen embankment slopes or protecting partitions can limit the land occupation through half, Extend provider lifestyles and decrease value with the aid of 20-50%.
