Steel-plastic geogrid

Product Description:

The steel-plastic composite geogrid is formed by wrapping high-tensile steel wire with high-density polyethylene into high-tensile strips, arranged in a plane at right angles through ultrasonic welding, and is a geosynthetic material designed for engineering needs with varying mesh diameters and wire counts to adjust the tensile force of the reinforcing strips. The steel-plastic reinforced geogrid is made by combining steel-plastic reinforcing strips through innovative technology. Due to its surface being compressed into a regular coarse pattern, it withstands immense tensile stresses and friction with the backfill, effectively limiting soil shearing, lateral extrusion, and upheaval. The greater stiffness of the reinforced soil layer facilitates the distribution of loads from the upper foundation in a more uniform manner to the underlying soft soil layer, significantly enhancing the soil's bearing capacity. The increased overall stiffness within the compression layer, attributed to the reinforced soil layer, aids in adjusting soil deformation. The reinforced soil composite layer formed with steel-plastic reinforced geogrid is a flexible structure, capable of absorbing seismic energy, thus demonstrating good seismic performance.

Steel-plastic grid characteristics:

1. The tensile force of the steel-plastic composite grating is borne by the high-tensile steel wire woven in the warp and weft, which generates a high tensile modulus under low strain capacity. The longitudinal and transverse ribs work协同 together, fully utilizing the locking effect of the grating on the soil mass.

2. The longitudinal and transverse ribs of the steel-plastic composite mesh are woven with steel wire, with the outer wrapping layer formed in one piece. The steel wire coordinates with the outer wrapping layer, resulting in a low elongation rate (not exceeding 3%). The main load-bearing unit of the steel-plastic composite geogrid is the steel wire, with a low creep deformation.

3. By treating the plastic surface during the production process, we press rough patterns to enhance the roughness of the grillage surface, thereby increasing the friction coefficient between the steel-plastic composite geogrid and the soil mass.

4. The width of the steel-plastic composite mesh can reach 6 meters, achieving an economical reinforcing effect.

5. The high-density polyethylene used in the steel-plastic composite grate ensures: It will not be eroded by acids, bases, salt solutions, or oils at room temperature; nor will it be attacked by water dissolution or microorganisms. Additionally, the high molecular properties of polyethylene are sufficient to resist aging caused by ultraviolet radiation. The longitudinal and transverse ribs of the grate work together after being subjected to force, preventing any cracking or damage at the joints. In actual engineering, after the filling material is compacted, it is not eroded by ultraviolet light and oxygen, thus fully meeting the requirements of construction projects.
