Engineering effect of steel plastic geogrid
Steel plastic geogrid:When the geogrid is used in the soft ground treatment, the location and the number of the geogrid should be determined according to the geological condition.When the filling height is greater than 4m, the geogrid to meet the minimum requirements of industry standards, the vertical and horizontal limit tension should not be less than 20kN/mWhen the filling height is between 3-4m, the vertical and horizontal tensile force of geogrid is not less than 40kN/mWhen the filling height is less than 3m, the geogrid vertical ultimate tension is not less than 50 kN/m, the elongation is less than 4%, the proposed use of GSZ60-60 type geogrid when the geogrid embankment excavation combination should be used when the bidirectional geogrid is not less than 40kN/m, should adopt the GSZ60-60 type of GeogridAs for the old road widening old road junction, referring to the method of reconstruction and extension of the use of Grid: where the fill height is larger than 3 meters away from the roadbed, roadbed cap at 20 cm of paving plastic composite grille, with vertical (vertical line direction) limit tension is greater than or equal to 60kN/m, the transverse (parallel line direction) ultimate tension greater than or equal to the plastic composite geogrid 20kN/m, elongation is less than or equal to 4%.
4, more suitable for deep sea operations, embankment reinforcement, fundamentally solve the other materials to do a long time due to the erosion of the sea cage caused by low strength, poor corrosion resistance, short service life and other technical problems.5, can effectively avoid the construction process by machine rolling, damage caused by the construction damage
1, high strength, small creep, adapt to all kinds of soil environment, can fully meet the use of high grade highway retaining wall.2, can effectively improve the reinforced bearing surface, occlusal function, interlocking greatly improve foundation bearing capacity, effectively restrain the soil lateral displacement of reinforced foundation, stable performance.3, compared with the traditional grid has greater strength, strong bearing capacity, corrosion resistance, anti-aging, friction coefficient, perforated uniform, convenient construction, long service life and other characteristics.
