Polyester geogrid used in railway, polyester geogrid high strength nylon industrial silk sea, through the mesh fabric weaving direction, coating and processing into a geogrid. In soft soil treatment and subgrade, embankment and other projects, improve and improve the quality of the project, reduce the cost of the project.

Polyester geogrid is used to protect railway ballast: when the vibration and wind and rain of the train lead to the loss of ballast, the ballast and geogrid are wrapped to prevent the loss of ballast and improve the stability of the subgrade; Polyester geogrid used in railway Retaining Wall: geogrid is used for the edge of the reinforced Railway retaining wall, for example, in the railway station and parking station, to extend the service life and reduce the maintenance cost ; reinforced earth retaining wall under the geogrid: the road beside the vertical retaining wall and the geogrid laid can improve the bearing capacity of the retaining wall; under the abutment foundation, it is easy to sink and jump. The geogrid movement is laid on the foundation of the abutment, which can improve the bearing capacity and stabilize the butt joint.

Polyester geogrid is a kind of high-density polyethylene (HDPE) as raw material, plastic sheet extrusion, stamping, heating, making the original distribution of scattering molecules reorientation fully improve the tensile strength and linear state of rigid geogrid. Polyester geogrid used in railway is used to lay the railway geogrid in the soil, and through the interlocking and engagement of the geogrid and the soil, an effective stress transfer mechanism is formed, which makes the local load quickly and effectively spread to the soil, with a large area, so as to restore the local failure stress and improve the purpose of the project life cycle.

Polyester geogrid used in railway. Polyethylene has outstanding advantages. Under the load of geogrid, the creep deformation tends to be small, and the creep strength is much better than geogrid and other materials, so as to improve the important role of the project in life. Polyethylene geogrid products are suitable for railway construction and reinforced earth retaining walls, dams, bridges, rivers, lakes, steep coastal slopes and geogrid projects. Polyester geogrid used in railway to improve the bearing capacity of retaining wall or dam, extend the service life, reduce the occupied area, shorten the construction period, reduce the cost and reduce the maintenance cost.

Polyester geogrid used in railway is extruded into polyethylene polymer through pressure sheet, then washed regular mesh, and then from the longitudinal direction. In this process, the polymer becomes a directional linear state and forms a uniform distribution. This kind of structure (elongation at 2% - 5%) and modulus strength, super early international standard very high strength and modulus.

Polyester geogrid used in railway from vertical to horizontal through extrusion of polymer, sheet forming, stamping process. It is also assumed that the structure can provide a more effective force in the soil and is suitable for filling a strong permanent foundation.
