Upgraded technology for Jiangxi Convex Joint Steel-Plastic Geogrids!
Release date:
2020-12-07
Jiangxi Yichun Convex Joint Steel-Plastic Geogrid It’s an upgraded version of steel-plastic geogrids—a newly developed grid that builds on the innovation of conventional steel-plastic geogrids. This improved model addresses key limitations of standard grids, such as their weak node peel strength (only 30N), susceptibility to weld-point cracking—which often leads to construction challenges and reduces their effectiveness in preventing lateral displacement. Thanks to optimized material formulations and refined construction techniques, the peel strength at the welded nodes now reaches a robust 500–600N, effectively overcoming the shortcomings of traditional steel-plastic geogrids. Additionally, the raised protrusions at the welded joints give this product its distinctive name. Jiangxi Yichun Convex Joint Steel-Plastic Geogrid 。
Jiangxi Yichun Convex Joint Steel-Plastic Geogrid The longitudinal and transverse tensile yield strength can reach 20–150 kN per meter, as verified by inspections conducted at the Quality Supervision and Inspection Centers for Transportation, Railway, and Water Resources sectors. Jiangxi Yichun Convex Joint Steel-Plastic Geogrid The yield elongation rate is ≤3%, and the product features a network structure formed by using a melt-injection bump-type connection for the transverse reinforcing bars. This design delivers high node strength, with the welded grid node exhibiting a shear resistance of ≥1.5 MPa. Additionally, the node thickness meets or exceeds 5 mm, while the maximum peel force at the bump-grid nodes reaches ≥400 N. The product has already been widely adopted in regions such as Beijing, Tianjin, Hebei, Hunan, and Fujian.
To Jiangxi Yichun Convex Joint Steel-Plastic Geogrid For instance, the plastic casing serves as a protective material for high-strength steel wires and also acts as the load-bearing component of the plastic grid. It boasts chemical properties that make it resistant to corrosion from acids, alkalis, and salts. Thanks to its scientifically formulated composition, it offers exceptional resistance to aging and oxidation, making it ideal for long-lasting engineering projects with a service life expected to exceed 100 years. Jiangxi Yichun Convex Joint Steel-Plastic Geogrid The effect of its use is also remarkable: its grid-like, convex-node structure in Yichun, Jiangxi, enhances the interlocking and gripping action between the grid and the soil/rock materials. This helps restrain lateral soil movement, boosts the foundation's load-bearing capacity, minimizes overall soil settlement, mitigates uneven settlement patterns, improves the foundation's overall performance, and even prevents cracking on the ground surface.
Use Jiangxi Yichun Convex Joint Steel-Plastic Geogrid It can also reduce project costs—several engineering examples have demonstrated that reinforced structures using this material can save 10% to 50% in construction costs compared to traditionally built projects of the same type. Moreover, using Jiangxi Yichun Convex Joint Steel-Plastic Geogrid It can shorten the construction period and is easy to install, making it an ideal material for land development projects.
Jiangxi Yichun Convex Joint Steel-Plastic Geogrid Production process flow:
a. Based on the product’s specifications and model, blend new PE raw material with recycled granules according to the desired peel strength, then accurately measure the proportions of each component.
b. After completing the mixing ratio, manually stir and blend the proportioned raw materials using a mixer. Then, add auxiliary ingredients such as color masterbatch and defoamer as required, ensuring thorough and uniform mixing.
c. Feeding the material: Add the uniformly mixed PE material into the extruder and preheat the extruder beforehand.
d. Based on the tensile strength of the strip, calculate the number of steel wires, place the wires on the wire rack, and get everything ready.
e. Using an extruder, PE material is heated to a molten state at high temperature. The spring steel wires are then arranged closely within the die according to the desired tension. Molten PE is injected around the wires, completely enveloping them, and rapidly cooled in cold water. This process forms a steel-plastic composite strip.
f. Welding: Place the fabricated strips into a high-frequency welding machine, then use an ultrasonic high-frequency welder to perform the high-frequency welding process.
