Unidirectional stretching plastic geogrid: Unidirectional stretching geogrid is formed by extruding polymer into thin plates, punching regular pore network, and then stretching longitudinally. In this process, the polymer is in a directional linear state and forms a long elliptical network with uniform distribution and high node strength. This kind of structure has quite high tensile strength and modulus, especially the products of our company have higher early tensile strength and modulus than international level (elongation is 2%-5%). It provides an ideal interlocking system for soil to bear and diffuse forces. The product has high tensile strength (> 150 Mpa) and is suitable for various soils. It is widely used as reinforcement material at present.
Purpose:
Unidirectional tension geogrid is a kind of high strength geosynthetics. It is widely used in dikes, tunnels, wharfs, highways, railways, construction and other fields.
Its main uses are as follows:
1. Enhancing the subgrade can effectively distribute the diffusion load, improve the stability and bearing capacity of the subgrade, and prolong the service life of the subgrade.
2. It can withstand larger alternating loads.
3. Prevent subgrade deformation and cracking caused by loss of subgrade materials;
4. Enhance the self-supporting capacity of the backfill behind the retaining wall, reduce the earth pressure of the retaining wall, save costs, prolong service life and reduce maintenance costs;
5. Combining with shotcrete and anchor concrete construction method for slope maintenance can not only save 30%-50% investment, but also shorten the construction period by more than twice.
6. Adding geogrids to subgrade and surface of highway can reduce deflection, reduce rutting, delay crack occurrence time by 3-9 times, and reduce the thickness of structural layer by 36%.
7. Suitable for all kinds of soils, no need to take materials from different places, save time and labor;
8. The construction is simple and fast, which can greatly reduce the construction cost.
