The polyester geogrid used in mining is made of high-strength polyester industrial filament, warp knitted directional woven grid fabric, and PVC coated geogrid. Polyester geogrid used in mining is applied to soft soil foundation treatment and reinforcement of subgrade, dike and other projects, so as to improve project quality and reduce project cost. So in such a case, some people may think that the price will fall as a result. The tensile strength of the filament is higher than that of the short filament. Because of the softness of the filament, it has certain tear resistance and good main functions, such as: reverse filtration, water filtration and reinforcement. Specifications range from 100g / m2 to 800g / m2. Polyester geogrid used in mining is mainly made of polyester fiber. The long or short fibers are laid into a network by different equipment and processes, and then the different fibers are interweaved with each other through processes such as weaving, binding and fixing each other to normalize the fabric, making the fabric soft, full and thick, so as to meet the use requirements of different thicknesses.
Polyester geogrid for mining is used to reinforce the soft soil subgrade of roads, railways, municipal roads and other roads, which can effectively improve the strength of the subgrade and delay the reflection cracks of the road. Polyester geogrid is used for mining to keep the slope surface flat and solid, and a layer of high-quality soil can be sprinkled first to facilitate plant growth. The cell shall be laid from top to bottom in the direction of main stress, so that the cell sheet weight is perpendicular to the road subgrade. Never lay crosswise. Riveting piles are nailed along the drainage ditch on both sides. Bamboo and wood piles can be used to open the lattice. Bamboo and wood piles can also be used in the middle and bottom of the lattice. Riveting piles on the top mainly play the role of hanging and riveting the lattice. Better materials, such as steel bars, should be used. For example, for a 5cm cell, its riveting pile shall be 2 × 5cm + 30cm, 40cm long. The riveting pile of the fully opened 510cm cell assembly should be 2 × 10 + 30, and the 50cm long steel bar must be perpendicular to the slope. The length of the riveting pile is required to be 2 times of the height of the cell itself plus 30 cm. The other main functions are the tensioning chamber during construction, and the available materials are relatively simple. After the cell is tensioned and riveted.
Polyester geogrid used in mining has made a great breakthrough in the treatment of road bed diseases and the application of fixed loose medium. With the further understanding of the characteristics of polyester geogrid used in mining, it has been found that it has irreplaceable advantages of other geomaterials (geotextile, geomembrane, geogrid, geobag, geogrid, etc.). The active zone 1 will still transfer the force to the transition zone 2, but because of the lateral restriction of the cell wall and the reaction force of the adjacent cells, as well as the friction force between the filler and the cell wall, the lateral movement tendency of the transition zone 2 and the passive zone 3 is restrained, so that the bearing capacity of the subgrade is improved. Through experiments, the apparent cohesion of medium dense sand can be increased by more than 30 times under the restriction of lattice. Obviously, if the shear resistance of subgrade material can be increased or the movement of three areas can be restrained, the bearing capacity of subgrade can be improved, which is the limit principle of geocell. Its purpose is to improve the shear resistance and friction of foundation materials
Polyester geogrid used in mining also depends on its toughness, and its strong toughness has a long service life. In the process of building water conservancy facilities, the polyester geogrid used in mining has achieved good results Polyester geogrid used in mining is a kind of geosynthetic material which is woven with polypropylene and polypropylene flat filament as materials. Such materials are usually used by small manufacturers and become low in price. There are many water conservancy projects, so the establishment of the project is more and more important. In view of its benefits to mankind, there are many geotextile manufacturers all over China now. In view of their functions, they have obtained one geotextile Generally, the products of small manufacturers are usually cheap, and the materials used are different, but also whitewash the situation, which has been praised by many people. The quality and price of products are different. There are many reasons for the price difference of geotextile.
