Geogrid is one of the main geosynthetics. Compared with other geosynthetics, it has unique performance and efficacy. It is often used as reinforcement material of reinforced earth structure or composite material. Geogrids are divided into four categories: plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp-knitted polyester geogrid. The grid is a two-dimensional grid or three-dimensional grid with a certain height made of polypropylene, polyvinyl chloride and other macromolecule polymers by thermoplastic or moulding. It is called geogrid when it is used in civil engineering. Geogrid has been widely used because of its high strength, small deformation, small creep, corrosion resistance and long service life. Here is a brief introduction to the concrete application of geogrid.

1. Geogrid plays an important role in road construction, mainly for strengthening roadbed and delaying aging. It is mainly used for soft foundation treatment, roadbed reinforcement, slope protection, bridge abutment reinforcement, wing wall, retaining wall, isolation and reinforced earth engineering.

2. The use of geogrids on railways can avoid the settlement and damage of Railways on soft soil foundation prematurely.

3. Geogrids are used in dikes, dams, rivers, canals, sea embankments, reservoir reinforcement and other water conservancy projects.

4. Enhancing the foundation of airport with geogrid can greatly improve the bearing capacity of runway and ensure the safety of aircraft taking off and landing.

5. Geogrid can be used in waste site treatment, power plant, ash dam engineering, coal mine, metallurgy, greening, enclosure and other fields.

6. Strengthening the soft foundation of building structure to improve the overall bearing capacity of the foundation.
