The role of Yuzhimu non-woven fabric as geotextile

Yuzhimu non-woven fabric is composed of heat bonded PP+PET material. So structurally stable, with good permeability and high tensile strength. Its function involves filtration, isolation, drainage, and protection. So it is widely used in fields such as civil engineering and environmental engineering, and its main functions include the following aspects:

1. Isolation function

Function: To prevent different materials (such as soil, sand and gravel, aggregates) from mixing with each other and maintain the independence of each layer structure.
Application:

• Separate the roadbed from the soft soil layer in road engineering to prevent infiltration of soft soil or sinking of crushed stones.
• Isolate the ballast from the underlying soil in the railway subgrade to improve stability.
• Isolate waste from the foundation layer in the landfill site.

2. Filtration and drainage function

Function: Allow water to pass through while preventing soil particle loss, achieving "permeable but impermeable soil".

Application:

• Wrap drainage pipes or gravel layers in drainage systems (such as blind ditches and slope drainage) to prevent clogging.
• Protecting bank slopes in river and coastal engineering to reduce soil erosion caused by water flow erosion.
• Assist in drainage and prevent soil erosion in agricultural irrigation systems.

3. Protective function

Function: Disperse stress, reduce damage to the structure caused by external mechanical forces or natural erosion.

Application:

• Slope protection: Covering the exposed soil surface to prevent wind and rain erosion (often combined with vegetation).
• Anti leakage layer protection: Covering above the geomembrane to prevent puncture damage.
• Temporary covering: Dust prevention and suppression on construction sites, or temporary protection of exposed ground during construction.

4. Reinforcement effect

Function: Enhance soil tensile strength and improve overall stability through friction.
Application:

• Soft soil foundation reinforcement to enhance bearing capacity.
• Layered laying in retaining walls and reinforced soil structures to reduce lateral deformation.

5. Environmental Protection and Ecological Restoration
Function: Assist in ecological restoration and control the spread of pollution.
Application:

• Used as an isolation layer in the remediation of contaminated sites to prevent the migration of pollutants.
• As a seed cloth or vegetation blanket carrier in vegetation engineering, it promotes plant growth.

6. Main advantages

• Permeability and soil retention: Balancing permeability and filtration to meet different engineering needs.
• Corrosion resistance and durability: resistant to acid, alkali, and microbial erosion, with a long service life.
• Convenient construction: lightweight and soft, easy to cut and lay, suitable for complex terrain.
• Economy: Low cost, can replace traditional sand and gravel filter layers, and reduce resource consumption.

7. Application category

• Road/railway engineering: roadbed isolation, drainage.
• Water conservancy engineering: dam filter layer, slope protection.
• Environmental engineering: landfill sites, pollution isolation.
• Agriculture and Landscape: Drainage Ditches, Ecological Slope Protection.
