Application of uniaxial geogrid in railway subgrade
Product Introduction
In railway engineering, uniaxial geogrids are hailed as the "strong reinforcement" of the subgrade. Unlike biaxial geogrids, uniaxial geogrids possess extremely high tensile strength in a specific direction (usually longitudinal), making them ideal for applications like railways where the stress direction is clearly defined and the loads are immense.
The core role of uniaxial geogrids: tensile reinforcement
When heavy-load trains (especially high-speed trains or heavy freight trains) pass over railway subgrades, they generate enormous downward pressure and lateral compressive forces.
Uniaxial stress optimization: During manufacturing, uniaxial geogrids undergo directional stretching, resulting in highly oriented molecular chains that give them extremely high elastic modulus and creep resistance in the primary stress direction.
Stress principle: When a train exerts downward pressure, the geogrid, through interlocking friction with the subgrade filler (crushed stone/soil), converts the vertical pressure into horizontal tensile force, thereby limiting the subgrade from "spreading out" to the sides.
