High Tensile Strength Three-Dimensional Composite Drainage Net with Excellent Chemical and UV Resistance for Landfill and Roadbed Projects

Product Introduction

Product Features

• High tensile strength: The added geogrid significantly improves the product's tensile strength (≥ 50kN/m) and tear resistance, suitable for large-area laying and areas prone to deformation.
• Stable drainage performance: The three-dimensional mesh core has a fixed structure, which is not easy to deform under pressure, ensuring the smoothness of the drainage channel.
• Good integration with soil: The geotextile and geogrid can enhance the friction between the product and the soil, improving the stability of the soil structure.
• Easy to construct: Lightweight and flexible, easy to cut and lay, reducing construction difficulty and improving work efficiency.

Application Fields

Product Installation

1. Base surface reinforcement: For large-scale projects or soft base surfaces, the base surface should be reinforced with geotextile first to improve the bearing capacity of the base surface.
2. Laying sequence: Lay the drainage net in the direction of water flow, with the geogrid layer facing the backfill soil. The longitudinal overlap width is 20cm, and the transverse overlap is 15cm. The overlap area should be pressed tightly.
3. Fixing with anchor bolts: Use high-strength anchor bolts for fixing, with a spacing of 1m. The anchor bolt heads should be covered with protective caps to prevent damage to the drainage net.
4. Layered backfilling: Backfill in layers, each layer thickness is 30-50cm, and compact each layer with a roller. During backfilling, avoid heavy machinery directly rolling on the drainage net to prevent damage to the mesh core.
