Take you to Know about the Geogrid in Construction
Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids, and polyester warp-knitted polyester geogrids. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of polypropylene, polyvinyl chloride, and other macro-molecular polymers by thermoplastic or molding.
We mainly introduce the mining grille for our industry. The mining grille is a 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 formed by biaxial stretching.
The mining geogrid is specially designed and manufactured for the false roof support and roadway 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 lightweight, 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 faces. 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.
Technical advantages
1. Friction is not easy to generate static electricity. In the underground 2. In the environment of coal mines, the average surface resistance of plastic mesh is below 1×109Ω.
3. Good flame retardant properties. It can reach the flame retardant properties specified by coal industry standards MT141-2005 and MT113-1995 respectively.
4. Easy to clean coal. The density of the plastic mesh is about 0.92, which is less than the density of water. During the coal washing process, the broken mesh floats on the water surface and is easily washed away.
5. Strong anti-corrosion ability and anti-aging.
6. Easy to construct and transport. The plastic mesh is relatively soft, and it is not suitable for workers to be scratched during construction, and it has the advantages of easy curling and bundling, mining grid cutting, and lightweight, so it is convenient for underground transportation, carrying, and construction.
7. It has a strong bearing capacity in both vertical and horizontal directions. Because this plastic mesh is biaxially stretched rather than woven, the mesh creep is small and the mesh size is uniform, which can effectively prevent the falling of broken coal and protect the safety of underground workers and the safety and security of mine workers.
Several types of geogrids are available in our company. If you need these devices, please contact us, and we will provide you with a professional product selection.
