High-performance geosynthetics
Railway subgrade stability and long life cycle solutions
Addressing three core challenges: soft soil bearing capacity, ballast loss, and slope protection, significantly reducing life-cycle maintenance costs.
Severe Challenges of Railway Engineering
Ballast particle displacement
Long-term high-frequency dynamic loads cause ballast particles to wear and break, and the track geometry exceeds the standard.
Soft soil foundation settlement
Uneven settlement is likely to occur in silty soil or collapsible foundations, which can endanger driving safety.
Slope erosion and instability
Heavy rainfall and dynamic load impacts triggered embankment landslides and bridge abutment slumps.
Track Bottom Reinforcement (Battery Stabilization)
Recommended Product: High-Nodal Stiffness Biaxial/Triaxial Geogrid
Interlocking Effect: The geogrid locks in the displacement of the crushed stone, forming a high-strength composite load-bearing layer.
Cost Optimization: Reduces ballast fill thickness by 30%-50%.
Extended Cycle: Extends maintenance cycle by 3-5 times.
Enhancing the Bearing Capacity of Soft Soil Foundations
Recommended Product: Long-filament nonwoven geotextile + reinforced geogrid
Stress Diffusion: Distributes concentrated loads evenly, effectively suppressing differential settlement.
Filtration and Pollution Prevention: Completely blocks "mud heave" and ensures a dry roadbed.
High and steep slopes and embankment protection
Engineering Challenges: Slope erosion, landslides, and differential settlement at bridge abutment transition sections caused by heavy rainfall.
Solution: Three-dimensional geocell system.
Implementation Results:
Lateral Constraint: The honeycomb structure provides strong physical constraints, preventing filler loss.
Ecological Regeneration: Supports vegetation growth, creates a green railway corridor, and enhances slope erosion resistance.
