Non woven geo fabricWhat is it ? Why do you need it!
PET high-performance non woven geo fabric (Polyester High-Performance Non-Woven Geotextile) reinforcement, filtration, drainage and soil stability. With the continuous development of engineering construction technology, geotextiles, geomembranes and geogrids are widely used in road construction, environmental protection, water conservancy projects, infrastructure construction and waste management. This article will deeply explore the characteristics, working principles, application fields, construction methods, market prospects and future development trends of PET high-performance non-woven geotextiles to help readers fully understand this important geotechnical material.
Non woven geo fabric Production process
- The production process of PET high-performance non woven geo fabric mainly includes the following steps:
- Raw material preparation: Select high-quality PET fiber as raw material.
- Opening and carding: The fibers are opened and arranged into a mesh by a carding machine.
- Needle punching or thermal bonding: The fibers are fixed together by needle punching or thermal bonding to form a geotextile with a certain thickness and strength.
- Post-treatment: Surface treatment is performed as needed, such as waterproof treatment, UV protection treatment, etc.
- Rolling and packaging: The finished product is rolled and packaged for transportation and storage.
Non woven geo fabric Application areas
- Soft soil foundation reinforcement: Laying PET non woven geo fabric on soft soil foundation can improve the bearing capacity of the foundation and reduce settlement.
- Slope protection: Laying PET non woven geo fabric on the slope can prevent soil loss and enhance the stability of the slope.
- Roadbed reinforcement: In road construction, PET non woven geo fabric can be used to strengthen the roadbed and improve the bearing capacity and service life of the road surface.
- Drainage system: Laying PET non woven geo fabric under the roadbed or building foundation can effectively drain the accumulated water and prevent water accumulation.
- Vertical drainage: Using PET non woven geo fabric in deep foundation pits or underground structures can form an effective vertical drainage channel and accelerate the discharge of groundwater.
- Ditch lining: Laying PET non woven geo fabric in drainage ditches can prevent soil erosion and extend the service life of ditches.
- Soil and rock separation: In landfill or dam construction, PET non woven geo fabric can effectively separate soil and rocks of different particle sizes and prevent fine particles from entering the drainage system.
- Filter layer: In water conservancy projects, PET geotextile can be used as a filter layer to prevent soil loss while ensuring smooth water flow.
Non woven geo fabric Construction preparation work
Before construction, the following preparations need to be done:
- Site survey: Understand the geological conditions and engineering requirements of the construction site in detail.
Material inspection: Ensure that the PET geotextile used meets the design requirements and technical standards.
Equipment preparation: Prepare the required construction equipment, such as laying machines, compactors, etc. - Laying method;
Manual laying: Suitable for small areas or areas with complex terrain, workers manually lay and fix.
Mechanical laying: Suitable for large areas or flat areas, use laying machines for rapid laying.
Layered laying: When multiple layers of geotextiles are required, lay them layer by layer and ensure that the connection between each layer is firm. - Fixing method
- Nail fixing: Use special geotextile nails to fix the geotextile to the ground.
Sandbag ballast: Place sandbags on the edge of the geotextile to increase its stability.
Concrete anchoring: Pour concrete at a specific location and embed the edge of the geotextile into the concrete for fixing.
How to choose the right PET nonwoven geotextile?
When choosing the right PET geotextile, you should consider the soil conditions, load requirements, permeability requirements and durability requirements of the project. By consulting professional suppliers or technical experts, you can customize the most suitable material specifications and parameters for the project.
Conclusion
PET high-performance nonwoven geotextile has become an indispensable key material in civil engineering due to its excellent physical properties, durability and wide application fields. PET geotextile plays an important role in soil reinforcement, drainage, anti-seepage, and environmental protection such as ecological restoration and landfills.
