Warp Knitted Polyester Geoglyph Can Strengthen Soft Soil Foundation
Production Introduction
Warp knitted dacron geoglyph is a new type of composite geomaterial, which is composed of dacron geoglyph and Dacron filament geotextile. This material is characterized by the combination of the advantages of both, not only has high tensile strength and low elongation, but also has good temperature resistance and high water permeability and filtration. In addition, it also has tear resistance, anti-dispersion, long service life performance.
Production Property
1. High strength and durability: Using high strength polyester fiber as raw material, made of warp knitting process, with extremely high tensile strength and small elongation.
2. Corrosion resistance and oxidation resistance: The material is resistant to chemical attack and the effects of environmental aging.
3. Strong bite force with the base material: there is a strong adhesion between the material surface and the base material.
4. Light weight and drainage: the characteristics of light weight make the construction more convenient, and have a certain drainage effect.
Production Application
1. Road, railway, airport and other pavement enhancement: can effectively improve the strength of the roadbed, delay the appearance of road reflection cracks.
2. Old pavement maintenance and widening: suitable for asphalt pavement and cement concrete pavement maintenance work.
3. Subgrade enhancement: used to improve the stability of subgrade.
4. Reinforcement of DAMS and river channels: it can strengthen the soft soil foundation and improve the bearing capacity and stability of the foundation.
5. Abutment foundation reinforcement: the laying of geogrid can improve the bearing capacity and avoid the phenomenon of jumping.
