The two-way geogrid is directly made of polyester by spinning, needling and consolidation. The specifications of geotextile are complete. The product specifications are randomly selected from 80-800gm. It is a kind of geosynthetic material applied in geotechnical engineering and civil engineering. It is made by the method of forming net and consolidation of polyester filament, and its fibers are arranged into three-dimensional structure.

In addition to good mechanical properties, two-way geogrid also has good vertical and horizontal drainage performance, good extension performance and high chemical stability performance such as biological resistance, acid and alkali resistance and aging resistance. At the same time, it has a wide range of pore size, zigzag pore distribution, excellent permeability and filtration performance. The width of steel plastic geogrid can reach 6 m to achieve high efficiency and economic reinforcement effect.

The two-way geogrid is a long elliptical network structure with uniform distribution and high joint strength. This kind of structure has appropriate high tensile strength and rigidity, which provides the soil with an ideal bearing force and a decentralized chain system. This kind of structure can provide a more useful bearing of force and a decentralized ideal chain system in the soil, which is suitable for the foundation reinforcement of large-scale permanent bearing.

The two-way geogrid can distribute the load uniformly. It can reinforce the soft soil through two important mechanisms: direct tensile stress and lateral displacement. Its fixation effect comes from the friction of the grid surface and the passive earth pressure produced by the transverse reinforcement of the grid under the load. If the geogrid is directly supported on the soft foundation and supported by the granular base, it can not only ensure the incompatibility between the granular material and the foundation soil, but also further strengthen the cohesion between the grid and the granular material. The base has tensile strength, thus improving the load capacity of the soft foundation.

The two-way geogrid can avoid premature settlement and damage to the soft foundation of the railway, and the two-way geogrid can lie on the railway subgrade, so that they form a rigid foundation of the pavement materials, which can effectively distribute the load, prevent the deformation of the subgrade, and improve its stability.

The laying of two-way Geogrid on the railway slope can prevent the sliding block of the rock, cause injury to people or vehicles, keep the railway unblocked, and the price of two-way geogrid and two-way geogrid with packaging ballast can prevent the loss of ballast and subgrade deformation, and improve its stability.
