High Tensile Strength Three-Dimensional Composite Drainage Net with Excellent UV Resistance and Stable Drainage Performance

This high-strength reinforced three-dimensional composite drainage net incorporates a layer of high-strength geogrid between the three-dimensional mesh core and the geotextile. The geogrid significantly enhances the product's tensile strength and tear resistance, while the three-dimensional mesh core maintains excellent drainage performance. Designed specifically for projects requiring both superior drainage efficiency and exceptional structural strength.

• High Tensile Strength: The integrated geogrid provides exceptional tensile strength (≥ 50kN/m) and tear resistance, making it suitable for large-area installation and deformation-prone areas.
• Stable Drainage Performance: The three-dimensional mesh core maintains a fixed structure that resists deformation under pressure, ensuring consistent drainage channel integrity.
• Enhanced Soil Integration: The geotextile and geogrid combination increases friction with soil, improving overall soil structure stability.
• Easy Installation: Lightweight and flexible design allows for easy cutting and laying, reducing construction complexity and improving work efficiency.

Ideal for large-scale water conservancy project drainage, high-speed railway and highway subgrade drainage, extensive landfill drainage systems, and deep foundation pit drainage. Particularly suitable for projects with large structural spans, high backfill loads, and demanding requirements for both drainage performance and structural stability.

1. Base Surface Preparation: For large-scale projects or soft base surfaces, reinforce the base with geotextile first to improve bearing capacity.
2. Laying Sequence: Install the drainage net in the direction of water flow with the geogrid layer facing the backfill soil. Maintain 20cm longitudinal overlap and 15cm transverse overlap, ensuring overlap areas are properly compressed.
3. Anchor Bolt Fixing: Secure with high-strength anchor bolts at 1m spacing. Use protective caps on bolt heads to prevent damage to the drainage net.
4. Layered Backfilling: Backfill in layers of 30-50cm thickness, compacting each layer with a roller. Avoid direct heavy machinery contact with the drainage net to protect the mesh core.
