Description

Introduction

Composite geogrid is a structurally unique geogrid composed of different materials, typically including polymer materials and other stronger materials such as fiberglass, polyethylene, etc. Composite geogrids combine the advantages of different materials and have higher strength, durability, and tensile performance.

The common structures of composite geogrids include biaxial tensile structures, multi-layer structures, biaxial tensile+uniaxial tensile structures, etc. The design of different structures can meet different engineering needs. The main functions and application areas of composite geogrids are similar to traditional geogrids, including road engineering, railway engineering, bridge engineering, water conservancy engineering, environmental engineering, and landscaping.

Applications

Geotechnical Engineering: In geotechnical engineering, composite geogrids can be used to support rock slopes, prevent rock collapse, reinforce slope structures, and improve slope stability.

Railway and Bridge Engineering: Used for reinforcing and supporting railway subgrades and bridges, enhancing the stability and load-bearing capacity of railway lines and bridge structures, and improving the safety of engineering.

Environmental protection engineering: In environmental protection engineering, composite geogrids can be used for slope protection, river restoration, lake shore reinforcement, etc., to prevent soil erosion and pollutant diffusion.
