Introduction
In-depth interpretation of GB/T 35752—2017 warp knitted composite geotextile technical standard
1. Background and significance of standard formulation
Warp knitted composite geotextile is a new type of engineering material that combines warp knitting fabrics and non-woven fabrics. It is widely used in water conservancy projects, road construction and other fields. The formulation of GB/T 35752—2017 fills the gap in domestic technical specifications in this field and provides a scientific basis for product quality control.
2. Comparative analysis of standard frameworks
| Standard dimensions | GB/T 35752—2017 | Internationally accepted standards | Difference analysis |
|---|---|---|---|
| Product classification | Glass fiber and synthetic fiber, with clear codes | Mainly divided according to material type | Detailed composite process requirements |
| Technical indicators | Longitudinal/transverse fracture strength, unit area mass deviation rate, etc. | Similar indicators, but different parameter ranges | Added dynamic performance test requirements |
| Test methods | Citing multiple national standard methods | Reference to international standards such as ASTM | More emphasis on localized application |
3. Interpretation of core technical requirements
Internal quality:Including basic indicators such as breaking strength and unit area mass deviation rate, as well as options such as dynamic perforation performance and UV resistance.
Appearance quality:Specifies the type and quantity of defects to ensure that there are no major defects on the surface of the product.
4. Practical application case analysis
GF-80/80-400-2 glass fiber warp knitted composite geotextile was selected for a water conservancy project, which meets the requirements of 80kN/m in transverse breaking strength and 400g/m² in unit area mass. Through on-site monitoring, the product bursting strength reached 1.7kN, which meets the requirements of GB/T 14800.
5. Implementation suggestions
- Strictly follow the standards for material procurement and construction acceptance
- Choose a suitable combination of technical indicators according to project requirements
- Strengthen the frequency of sampling of incoming materials to ensure stable quality
- Pay attention to the impact of environmental factors on material performance and take corresponding protective measures
