Geogrid is a widely used geotechnical material. Its development is like the development process of geogrid manufacturers. There are setbacks and brilliance. In recent years, the application of biaxially oriented plastic geogrids in road engineering has become more and more extensive. It plays different functions in different applications, such as isolation, anti-seepage, reinforcement, filtration, drainage and protection, etc. It is believed that the application prospect of geogrid in future highway and urban road construction projects will be brighter.
The performance of the inorganic material of the geogrid:
The performance of glass fiber geogrid is to solve the problem of reflection cracks caused by the transformation of rigid pavement into flexible pavement. Generally, new geotechnical material fiberglass grid is used in the design of highway renovation projects to suppress and delay the cracks caused by the reflection of asphalt concrete pavement. , thereby increasing the service life of the road surface. Fiberglass geogrid is a geocomposite material made of glass fiber through a special coating process.
The main components of glass fiber are: silicon oxide, which is an inorganic material. Its physical and chemical properties are extremely stable, and it has high strength, high modulus, no long-term creep, good wear resistance and thermal stability. Because the surface is coated with special modified asphalt, it has dual composite properties, which greatly improves the wear resistance and shear capacity of the geogrid. Glass fiber geogrid is made of glass fiber, which has high resistance to deformation, and the elongation at break is less than 3%.
As a reinforcing material, it is extremely important to have the ability to resist deformation under long-term load, that is, creep resistance. Glass fiber will not creep, which ensures that the product can maintain its performance for a long time. Since the melting temperature of glass fiber is above 1000°C, this ensures that the glass fiber geogrid can withstand higher temperatures during the paving operation and has good thermal stability.
The material coated by the glass fiber geogrid in the post-treatment process is designed for the asphalt mixture, and each fiber is fully coated, which has a high compatibility with the asphalt, thus ensuring that the glass fiber geogrid can be The asphalt layer will not be isolated from the asphalt mixture, but will be firmly combined. After being coated with a special post-treatment agent, the fiberglass geogrid can resist all kinds of physical wear and chemical erosion, as well as resist biological erosion and climate change, ensuring that its performance is not affected.
About the mining function of geogrid:
Mine grille is a kind of plastic mesh for underground coal mines. It is made of polypropylene as the main raw material. After being treated with flame retardant and antistatic technology, it is a "double-resistance" plastic mesh with an overall structure formed by biaxial stretching. The product is easy to construct, low cost, safe and beautiful
Mine geogrids are also called double-stretched plastic mesh false roofs in coal mines, referred to as false roof meshes. The mining geogrid is specially designed and manufactured for the false roof support and roadway support support of the coal mine underground mining face. It is made of several high molecular polymers and filled with other modifiers. , Punching, stretching, shaping, coiling and other processes are manufactured. Compared with metal textile mesh and plastic woven mesh, mine geogrid has the characteristics of light weight, high strength, isotropy, anti-static, non-corrosion and flame retardant. It is a new type of coal mine underground support engineering and civil engineering. Use mesh grid material. Mining geogrids are mainly used for false roof support projects in coal mine underground mining face, and mining grids can also be used as earth-rock anchorage and reinforcement for other mine roadway engineering, slope protection engineering, underground civil engineering and traffic road engineering. Material, mine grating is one of the best alternatives to plastic textile mesh.
