Needle-punched geotextiles for railway engineering

Descripción

Railway engineering needle punched geotextile is a high-strength nonwoven fabric made from polyester (PET) or polypropylene (PP) staple fibers. Manufactured through advanced needle punching processes, this geotextile features excellent tensile strength, durability, and permeability. It is specifically designed for railway construction projects, including subgrade reinforcement, drainage, ballast stabilization, and prevention of contamination between soil layers. It helps to improve track performance and extend the lifespan of railway infrastructure.

Key Specifications

Características

Durability: Geotextiles are made of high-quality materials, offering strong durability and anti-aging performance, ensuring long-term effectiveness.

Ease of Construction: Geotextiles are highly flexible and adaptable, allowing for easy cutting and splicing to suit various complex terrains during construction.

Cost-Effectiveness: Compared to traditional impermeable materials, geotextiles are more affordable, significantly reducing the cost of highway projects.

Función

Reinforcement: In road and railway construction, geotextiles enhance soil tensile strength and stability, preventing deformation or collapse under heavy vehicle or train loads.

Separation: Geotextiles act as a barrier between soil layers with differing properties, preventing intermixing and ensuring long-term structural integrity.

Drainage: Geotextiles facilitate water drainage in road or railway subgrades, preventing water accumulation that could weaken stability and durability.
