    Three-Dimensional Composite Drainage Network Landfill Site Railway Tunnel Filtration

    ●Innovative Material: This is a new type of drainage geotextile made up of a three-dimensional geonet sandwiched between two needle-punched non-woven geotextiles.

    ●Advanced Structure:

    Tri-dimensional thick vertical ribs enhance durability.

    Inclined ribs on the top and bottom improve drainage efficiency.

    ●Comprehensive Performance:

    Functions in filtration, drainage, ventilation, and protection.

    Effectively replaces traditional sand and gravel systems.

    ●Efficient Water Management:

    Rapidly drains underground water.

    Blocks capillary water under high construction loads.

    Maintains optimal thickness for enhanced water conductivity.

    ●Additional Benefits:

    Provides isolation for foundations.

    Reinforces structural integrity.

      Characteristics of Product

      1. Strong drainage capacity (equivalent to one meter thick gravel drainage).
      2. High tensile strength, able to withstand high-pressure loads for a long time (able to withstand compression loads greater than 3000kPa).
      3. Reduce the probability of geotextile embedding and maintain long-term stable hydraulic conductivity.
      4. Corrosion resistance, acid and alkali resistance, long service life, low cost, and convenient construction.
