Geogrid is a major geosynthetic material. High strength steel wire (or other fibers), specially treated with polyethylene (PE) or polypropylene (PP) and added with other additives, is extruded to form a composite high-strength tensile strip with rough embossing on the surface, which is a high-strength reinforced geotextile strip. From this single strip, it is formed by welding its junction points with a special strengthening bonding fusion welding technology (ultrasonic welding technology) by arranging or clamping at a certain distance vertically and horizontally, and forming a reinforced geogrid Test items: Physical properties: width, appearance, mass per unit area, thickness, equivalent aperture, vertical permeability coefficient, thickness of mold bag flushing, mold bag length/width, width, density, roughness height, oxidation induction time (OIT) (standard), water vapor permeability coefficient, appearance quality, width and deviation, mass per unit area of geotextile, thickness and deviation, carbon black strength, height and deviation of geotextile cell, thickness of geotextile cell Geocell welding distance and deviation, unit area mass of bentonite waterproof blanket, bentonite expansion index, blue absorption, permeability coefficient, resistance to static water pressure, filtration loss, length and deviation, etc. Mechanical properties: longitudinal and transverse fracture strength and elongation, bursting strength, longitudinal and transverse tear strength, sewing strength, tear strength, longitudinal and transverse yield strength (stress) and elongation, longitudinal and transverse fracture strength (stress) and elongation, longitudinal and transverse Transverse right angle tear strength, puncture strength, longitudinal and transverse dimensional stability, tensile strength, peel strength, bursting strength, longitudinal and transverse tear strength, tensile yield strength of format sheets, tensile strength of welded joints, elongation under high load Reliable performance: acid and alkali resistance (strength retention rate), UV resistance (strength retention rate), bentonite durability Function of testing report:1.
