Steel-Plastic geogrid engineering application is very extensive. When geogrid is applied to soft foundation treatment, the location and number of layers of the steel-plastic geogrid should be determined according to the geological conditions, and the steel-plastic geogrid should also be determined according to the height of the subgrade filling. The design strength of the geogrid.


(1)  When the height of the fill is greater than 4m, it is sufficient to meet the low requirements of the industry standard, and the vertical and horizontal tensile force should not be less than 20kN/m


(2)  When the filling height is between 3-4m, the vertical and horizontal tensile force of the steel-plastic geogrid shall not be less than 40kN/m


(3)  When the filling height is less than 3m, the vertical and horizontal tensile force of the geogrid is not less than 50 kN/m, and the elongation is less than 4%. It is recommended to use the GSZ60-60 geogrid


(4)  When the geogrid is used in the subgrade filling and excavation joint, the two-way geogrid of not less than 40kN/m should be used, and the GSZ60-60 geogrid should be used.


When used in the old road to widen the junction of the new and old roads, where the height of the subgrade is greater than 3 meters, the steel-plastic composite geogrid shall be added at a distance of 20 cm from the top of the subgrade, and the longitudinal (vertical route direction) tensile force shall be greater than or equal to 60kN /m, the steel-plastic composite geogrid with transverse (parallel route direction) tensile force greater than or equal to 20kN/m, elongation ≤4%.


Steel-Plastic geogrid engineering application should select the appropriate specifications according to the actual situation of the project to maximize the advantages of the geogrid.
