Dacron Geogrid

The polyester fiber warp knitted geogrid is made of high-strength polyester fiber. Using warp knitting directional structure, the warp and weft yarns in the fabric have no bending state between each other, and the intersection points are bundled with high-strength fiber filaments to form a firm bonding point and give full play to its mechanical properties, and the high-strength polyester fiber warp knitted geogrid has high tensile strength, small elongation force, large tear strength, small difference in vertical and horizontal strength, ultraviolet aging resistance, wear resistance, corrosion resistance, light weight, and strong interlocking force with soil or gravel, which has a significant effect on enhancing soil shear resistance and reinforcement to improve the integrity and load capacity of soil.

Features: 
1. It has extremely high tensile strength 
2. The elongation is small 
3. Erosion resistance and aging resistance 
4. It has a strong occlusion force with the base material 
5. Light weight and drainage

use 
1.Warp knitted polyester geogrid is used for the reinforcement of soft soil subgrade of highways, railways, municipal roads and other roads, which can effectively improve the strength of subgrade and delay the reflection cracks of roads. 
2.The reinforcement and isolation of embankments and rivers in the warp knitted polyester geogrid water conservancy project reinforces the soft soil foundation, enhances its protective capacity, and improves the bearing capacity and stability of the foundation. 
3.Warp knitted polyester geogrid is used for embankment slope reinforcement, retaining wall reinforcement, enhance the overall strength, highway, railway, water conservancy and other soft soil foundation reinforcement. 
4.Warp knitted polyester geogrid is used for railway slag protection: due to the vibration of the train and the wind and rain, resulting in the loss of ballast slag, the geogrid is used to wrap the ballast to prevent the loss of ballast and improve the stability of the roadbed; 
5.Warp knitted polyester geogrid is used for railway retaining walls: geogrids are used for retaining wall reinforcement on railway sides, such as platforms and freight platforms in railway stations, which can prolong the service life and reduce maintenance costs; 
6.Warp knitted polyester geogrid is used to reinforce the retaining wall: the geogrid is paved next to the highway and the vertical retaining wall, and the abutment foundation that can improve the retaining wall is generally easy to sink downward, and the phenomenon of jumping cars occurs, and the geogrid is laid under the abutment foundation, which can improve the bearing capacity and stabilize the abutment.

Construction method 
The grid should be paved on the coarse-grained stone of the asphalt layer of the construction pavement, the original pavement should be leveled first, and the construction should be carried out after finishing, trimming and cleaning, and the ordinary grid needs to be fixed with specific steel nails The grid lap is connected, the joint is transversely greater than 5cm, and the longitudinal direction is greater than 10cm.
