Staple Fiber Nonwoven Geotextile for High-Speed Rail

Haoyang Environmental Co., Ltd. proudly presents our Staple Fiber Nonwoven Geotextile, engineered specifically for high-speed rail applications. This advanced material provides essential reinforcement, ensuring stability and safety for rail infrastructure while addressing environmental concerns.

Characteristics of Staple Fiber Non-woven Geotextiles

Lightweight: The material of staple fiber non-woven geotextiles is lightweight, with good air permeability and water permeability, helping to maintain the humidity and stability of the soil.

High strength: Staple fiber non-woven geotextiles have high tensile strength and tear strength, able to effectively resist the action of external forces and ensure the stability of the project.

High durability: Staple fiber non-woven geotextiles have good durability and anti-aging properties, able to be used for a long time under adverse environmental conditions.

Easy to construct: Staple fiber non-woven geotextiles have good flexibility and toughness, easy to construct and transport, able to adapt to various complex construction environments.

Application of Staple Fiber Non-woven Geotextile

Subgrade reinforcement: In high-speed rail construction, the stability and  reliability of the subgrade are crucial. Staple fiber non-woven geotextiles can effectively improve the load-bearing capacity and stability of the subgrade, ensuring the safe operation of trains.

Tunnel waterproofing: Waterproofing is crucial in high-speed rail tunnel construction. Staple fiber non-woven geotextiles can effectively prevent the leakage of groundwater, ensuring the normal use and safety of tunnels.

Track cushion: Staple fiber non-woven geotextiles can be used as a track cushion, able to effectively distribute the pressure of trains, improving the stability and service life of the tracks.

Sound barrier: Noise pollution is also a problem that needs to be addressed in high-speed rail construction. Staple fiber non-woven geotextiles can be used as a sound barrier, able to effectively reduce noise during train operation, improving the quality of life for residents living along the line.

One actual application case of Shandong Haoyang Environmental Co., Ltd. in high-speed railway construction:

（In order to ensure the smoothness of high-speed trains during high-speed travel, one of the most important issues in high-speed railway construction is to control the deformation of the subgrade. This deformation occurs in areas with abrupt changes, such as the transition between the abutment and the subgrade, the tunnel exit, etc. This change causes an uneven additional impact force on the high-speed moving wheels, resulting in uncomfortable driving conditions, and in severe cases, reducing the service life of the structure and even causing danger. This kind of disease increases the expensive maintenance and treatment costs, so the use of geosynthetics in the bridge-road transition section can effectively overcome this problem, but the quality requirements for geosynthetics are relatively high. Our company's various products are widely used in the construction of high-speed railways:

1.  Polypropylene staple fiber nonwoven geotextile: high strength, good extensibility, large deformation modulus, acid and alkali resistance, corrosion resistance, etc.

2.  Biaxially oriented geogrid: high strength, low elongation, excellent reinforcement and enhancement, and reduction of bumps and shocks in transition sections.）

As a building material with excellent performance, Staple fiber non-woven geotextiles have been widely applied in high-speed rail construction. With lightweight, high strength, high durability, and easy to construct properties, they can effectively improve the stability and safety of projects. In future high-speed rail construction, staple fiber non-woven geotextiles will receive more widespread application and development.
