Warp Knitting Polyester Geogrid Fabric for Railway Project

Warp Knitting Polyester geogrid fabric is fabricated by the complex knitting process using high tenacity, high oriented polyester filament to provide superior engineering and long term design strength properties.  BPM warp knitting geogrid is specifically designed for improved tensile reinforcement capacity in two principle directions. Our warp knitting polyester geogrid is designed to possess excellent mechanical and chemical stability while remaining biologically resistant to soil microorganisms. It is utilized in demanding construction installations and soil reinforcement applications, where it develops uniaxial strength. Additionally, it offers enhanced protection against chemicals, mechanical stress, and ultraviolet radiation.

Railway embankments are essential structures that bear the gravitational and dynamic forces of trains, forming the foundation for tracks. They are located in various terrains, geological formations, and climatic conditions, making them susceptible to hazards such as floods, landslides, collapses, and earthquakes. Geogrid fabric is widely used to reinforce railway subgrades, providing enhanced stability and strength.

Two commonly used types of geogrid fabric for this purpose are biaxially-stretched plastic geogrid and polyester geogrid. These materials possess high tensile strength, resistance to high temperatures and corrosion, lightweight properties, and are easy to construct with. They are also resistant to aging and compatible with cement, soil, and fragmented materials. Warp-knitted polyester geogrid fabric, in particular, is suitable for reinforcing embankments, road foundations, slope protection, cave wall reinforcement, and supporting structures in large-scale projects like airports, parking lots, and dockyards. Geogrid fabric finds widespread applications in railways, highways, and roads.

1 Appplications of Warp Knitting Polyester geogrid fabric for Aircraft runways 

• Reinforcement of iron roadbeds

Geogrid fabric  is used to reinforce the railway subgrade. Composite materials and road surface materials are integrated together to effectively distribute loads, prevent the loss of road slag and deformation of the roadbed, improve the stability of subgrade and withstand greater variable loads.

• Railway track slag protection

Due to train vibration and wind and rain, the road slag is lost. It is wrapped with geosynthetics to prevent the loss of ballast and improve the stability of roadbed.

• Railroad Retaining Walls

Geogrid fabric are used to reinforce the retaining walls on the side of the railway. For example, the platform and the cargo platform in the railway station can extend the service life and reduce maintenance costs.

• Railway slope protection

Geogrid fabric is used for slope protection on both sides of the railway to prevent stones and fine soil from sliding down, then increase the service life of the railway and reduce maintenance costs.

2 Why Chose Warp Knitting Polyester Geogrid Fabric for Railway Project

In 2017, an inspection team from China Railway Corporation visited our company to assess our GSJ100-100 biaxial warp knitting polyester geogrid fabric, which is specifically designed for reinforcing railway projects. During their visit, the inspection team thoroughly examined our production capacity and the quality of our geogrid fabric.
