Steel-plastic geogrid is a major geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as a reinforcement of reinforced earth structure or a composite material. Supply steel plastic geogrid.In order that everyone can better understand its related knowledge, today I will introduce its use and design application.

Uses: Steel-plastic geogrids can be used in highways, railways, embankments, abutments, construction access roads, wharves, revetments, flood protection dikes, dams, tidal flats, cargo yards, slag yards, airports, sports fields, environmental protection buildings, soft soil foundation reinforcement, Civil engineering of retaining walls, slope protection and pavement resistance.

Design application: When the geogrid is applied to the treatment of soft foundations, the position and number of layers of the additional grid should be determined according to the geological conditions, and the design strength of the steel-plastic geogrid should also be determined according to the height of the subgrade fill. When the soil height is greater than 4m, it is sufficient to meet the low requirements of the industry standard, and the longitudinal and horizontal tensile force should be not less than 20kN / m. When the filling height is between 3-4m, the longitudinal and horizontal tensile force is not less than 40kN / m. When it is less than 3m, the longitudinal and lateral tension is not less than 50 kN / m, and the elongation is less than 4.It is recommended to use GSZ60-60. When the steel-plastic geogrid is used for the subgrade filling and excavation joint, the two-way not less than 40kN / m, The GSZ60-60 type should be used. When used to widen the old road with the old and new roads, the roadbed filled with a height greater than 3 meters should be covered with a steel-plastic composite grid at a distance of 20㎝ from the roadbed cap. ) Steel-plastic composite grid with tensile force greater than or equal to 60 kN / m and transverse (parallel route direction) tensile force greater than or equal to 20 kN / m, with an elongation of ≤4.
