Classification of plastic geogrid
Three, the application of one-way plastic geogrid:Unidirectional plastic geogrid is a kind of high strength geosynthetics. Widely used in dams, tunnels, docks, highways, railways, construction and other fields.Three, one-way plastic geogrid its main purposes are as follows:1 strengthen the roadbed, can effectively distribute the diffusion load, improve the stability and bearing capacity of the roadbed, prolong the service life;2 can withstand greater alternating load;3 to prevent the roadbed material loss caused by roadbed deformation, cracking, one-way plastic geogrid4 to make the retaining wall after the filling capacity, reduce the earth pressure of retaining wall, save cost, prolong service life, and reduce maintenance costs;5 combined with spraying anchor concrete construction method for slope maintenance, not only can save 30% - 50% investment, but also can shorten the construction period more than doubled;6 in the roadbed and surface of the road to join the geogrid, can reduce the deflection, reduce the rut, the delay time of 3 to 9 times, can reduce the structure layer thickness of up to 36%;7 applies to all kinds of soil, no need to draw materials, save time;8 the construction is simple and quick, can greatly reduce the construction cost.
2, to highlight the advantages of geogrid is deformation under sustained loading (creep) tendency is very small, creep strength is much better than other materials geogrid, plays an important role in improving the service life of the project.3, the mesh grille and soil interlock and interlock function, constitute an efficient stress transfer mechanism, so that local load can be quickly and effectively spread to a large area of soil, to reduce the local failure stress, improve the service life of engineering.Three, the application of one-way plastic geogrid:Unidirectional plastic geogrid is a kind of high strength geosynthetics. Widely used in dams, tunnels, docks, highways, railways, construction and other fields.
First, what is a one-way plastic geogrid: one-way plastic geogrid is a high density polyethylene (HDPE) as raw material, through the extrusion press into a thin plate and then the rules of the hole network, and then the longitudinal tensile geogrid.Two, what are the characteristics of one-way plastic geogrid:1, the polymer into a linear state and the formation of a uniform distribution, high strength of the node of the long elliptical mesh integral structure. This kind of structure has high tensile strength and rigidity, and it provides the ideal chain system of bearing and diffusion of soil.
