Warp-knitted polyester geogrid composite geotextile is a self-adhesive polyester geogrid composite polyester staple fibre geotextile. The warp-knitted polyester geogrid is a new type of high quality geotechnical substrate to enhance the road base, using high strength polyester fibres or polypropylene fibres as raw materials, using warp-knitted directional structure, the warp and weft yarns in the fabric are not bent to each other, the intersection of high strength fibres filaments bundled together to form a solid bond, giving full play to its mechanical properties. The width is 1-6 metres and the length is 50-100 metres.
Polyester staple geotextiles are permeable geosynthetics made from synthetic fibres by needling. Geotextiles are one of the new material geosynthetics, finished in the form of cloth, generally with a width of 4-6 metres and a length of 50-100 metres.
Main functions: pavement, road base reinforcement, back filtration, drainage, protection and isolation. Features and performance.
1、High tensile strength, low elongation
2、High modulus of elasticity
3、Good temperature resistance
4、High water permeability, back filtration
5、Tear resistance, anti-dispersion, long service life
Warp-knitted polyester geogrid composite geotextile Application areas.
1、It is used for reinforcing the soft soil roadbed of highways, railways and municipal roads, which can effectively improve the strength of the roadbed and delay the reflection cracks of the road.
2、The reinforcement and isolation of embankments and river channels in water conservancy projects can strengthen the soft soil foundation, enhance its protection capacity and improve the bearing capacity and stability of the foundation.
3、It is used for reinforcement of embankment slope, reinforcement of retaining wall to enhance the overall strength, reinforcement of soft soil foundation of highway, railway, water conservancy, etc.
4、Used for railway slag protection, due to train vibration and wind and rain, causing slag loss, using geogrid to wrap the slag to prevent slag loss and improve the stability of the roadbed.
5、Used for railway retaining wall, geogrid is used to strengthen the retaining wall on the railway side, such as the platform and freight platform in the railway station, which can extend the service life and reduce the maintenance cost.
6、Used for reinforced retaining wall, adding geogrid in the highway side and vertical retaining wall, can improve the bearing capacity of the retaining wall.
7、The foundation of the bridge platform is generally easy to sink downwards, and the phenomenon of jumping traffic occurs, laying composite geogrid under the foundation of the bridge platform can improve the bearing capacity and stabilise the bridge platform.
