Our Geotextiles Products in New Railway Construction Project
The high-strength polypropylene filament needle-punched geotextile is made of polypropylene, which is formed by heating and melt spinning, high-strength air drafting, forming a net under negative pressure, and needle-punching to form a cloth. At present, the technology and high-strength polypropylene filament needle-punched geotextiles have been domesticated, which has changed the status of foreign monopoly technology and almost all domestic filament fabrics are PET filament fabrics, ending the long-term dependence on imports in China's engineering applications.
High-strength polypropylene needle-punched and non-woven geotextiles will play an important role in the construction of water conservancy, hazardous waste landfills, tailings depots, airports, high-speed rail and other projects with their excellent characteristics. In the application of railway bridges, in order to block the impact of the expansion and contraction of the bridge due to temperature changes on the longitudinal connection track structure, reduce the interaction between the track system and the bridge, and ensure the stability and smoothness of the track structure.
