Hunan plastic geogrid manufacturer price one-way plastic geogrid manufacturer
Characteristics of plastic geogrid: mechanical properties: due to the directional stretching during the manufacturing process, the polymer molecules are oriented along the stretching direction, strengthening the bonding force between the molecular chains, greatly improving its tensile strength, even greater than the strength of mild steel, but the elongation is very small. As the interlocking force of soil and stone increases in the grid, the friction coefficient between them also increases significantly. Creep property: creep property refers to the ability of geogrid to bear constant load within a certain period of time with 10% deformation allowed. The test shows that plastic geogrid has small deformation and good creep resistance under long-term continuous load.
Laying a certain plastic tensile geogrid in the soil can improve the strength and deformation characteristics of the soil in different degrees. In reinforced soil technology, the interface effect between geotechnical composition data and reinforced soil is a main parameter of reinforced soil. In order to apply a certain geotechnical data to a certain kind of soil, it is necessary to study the interface effect characteristics between them. In the process of pulling out the plastic geogrid, in addition to the resistance between the filler soil and the longitudinal reinforcement and the sliding interval of the grid, the normal stress, the external friction between the filler soil and the transverse rib, there is also the resistance between the filler soil and the transverse rib, which is closely related to the composition, density, thickness of the transverse rib, etc.
The research on the operation mechanism and action under the earthquake effect has just begun, and has announced the useful effect. The reinforced soil technology is still used in the non seismically active areas in domestic highway and railway projects. In the reinforced soil planning, when selecting the geogrid data, the mesh size of the geogrid should not be too large, otherwise the stiffness of the ribs will be reduced, the bite force will be reduced, and the geogrid will be simply damaged.
