Geogrid is a two-dimensional grid-like grid or a three-dimensional grid grid with a certain height, which is made of polypropylene, polyvinyl chloride and other high molecular polymers through thermoplastic or molding, and is widely used in civil engineering.
Geogrid stretching technology mixes high-density polyethylene or polypropylene with modifiers and additives, and extrudes and calenders through an extruder to produce high-quality plates with precise thickness control and smooth and flat surfaces.
The geogrid has a high tensile modulus, so under normal circumstances, it can be considered as a rigid rib wall according to the standard, but if the height of the reinforced retaining wall exceeds a certain height, the geogrid manufacturer The tensile modulus of will be relatively flexible, so for the internal stability analysis of infinite reinforced earth retaining wall, the results of these two forms of damage should be considered in general.
Geogrid has the characteristics of light weight, good overall continuity, high tensile strength, corrosion resistance, good anti-microbial corrosion, and convenient construction. It is widely used in high fill slope treatment projects. Compared with traditional reinforcement methods such as retaining walls, protective walls, and anchors, geogrids have the advantages of fast construction speed, simple construction, and low cost. Due to the use of steep slopes, the area is small and the project cost is low. 20% ~ 50%. In industrial and civil buildings, there is little contrast because of the usual selection, but in the slope treatment project of this project, the general contract design institute hired a design institute with experience in geotechnical engineering to design the slope treatment project. Retaining wall, protective wall, anchor and other reinforcement methods.
