Steel plastic geogrid with convex node

The steel-plastic geogrid with convex joints is a new type of steel-plastic grille suitable for new construction requirements. The steel wire is wrapped in high-strength strip by high density polyethylene and welded by ultrasonic wave. The tension of the ribbon is changed by different aperture and number of roots according to engineering requirements. Through the treatment of plastic surface in production engineering team, the joints are welded into protruding joints to melt the joints into one, so as to enhance the strength of the joints and increase the friction coefficient of the ribbon surface. These functions make the composed grids have the ability to resist the horizontal shear force from the fillers, improve the bearing capacity of the soft foundation and impede the formation of soil rupture, so as to meet the requirements of the joints for super-strong engineering.

Product performance

1. High tension: The ultimate tensile strength of each meter can reach 20-150 kN. It is tested by the quality supervision and inspection center of the three finished products of transportation, railway and water conservancy.

2. Small deformation: Yield elongation of steel-plastic grid with convex joints is less than 3.

3. High node strength: Cast convex node steel-plastic grid is used to connect longitudinal and transverse ribbed grids. Its joint strength is high. The shear strength of welded grids is more than 1.5 MPa, and the ultimate peeling force of convex node grids is more than 500 N.

4. Long service life: Plastic is a material for protecting high-strength steel wire and plastics grille. It has anti-aging and anti-oxidation properties by scientific formula. It is suitable for all kinds of permanent projects, and its service life can reach more than one hundred years.

5. The effect is good: grid mesh casting convex junction structure can restrain the lateral displacement of soil, enhance the bearing capacity of foundation, reduce the overall settlement of soil and improve the uneven settlement of soil, enhance the overall performance of foundation, and prevent the surface layer from splitting.

6. Cost saving: Through several engineering examples, it is proved that the cost of reinforced earth engineering constructed with this material can be saved by 10%-50% compared with similar projects constructed by traditional methods.

7. The laying and positioning of grilles are extremely simple and easy to smooth. Width of 2m-6m, fewer joints, can be connected through lock, shorten the construction period.
