In the realm of modern geotechnical engineering, projects such as tunnel construction, slope stabilization, and mining operations often grapple with harsh environmental conditions, including corrosion, high loads, and electromagnetic interference. SupAnchor, a leader in geotechnical solutions, has introduced the SupFRP® GFRP Solid Bolt to address these challenges. This product exemplifies the company's commitment to innovation, providing a durable alternative to traditional steel bolts and hollow bar anchors. As part of SupAnchor's comprehensive self drilling anchor system portfolio, this solid bolt enhances reliability in critical infrastructure projects across Europe and America, where safety and longevity are paramount.
The SupFRP® GFRP Solid Bolt is engineered with a solid structure from high-quality Glassfiber Reinforced Polymer, eliminating the vulnerabilities of hollow designs while retaining benefits like corrosion resistance and lightweight properties. This makes it an ideal component in geotechnical reinforcement systems, particularly in scenarios requiring high tensile strength and adaptability. Key parameters, such as guaranteed tensile load and diameter, ensure consistent performance under varying geological stresses. For instance, in slope stabilization or tunnel support, the bolt's high load-bearing capacity prevents failures, while its non-conductive nature safeguards sensitive equipment. The following table summarizes critical technical data for different models, highlighting how these specs address common engineering challenges like weight reduction and corrosion mitigation.
| Model | Outside Diameter (mm) | Guaranteed Tensile Load (kN) | Weight (kg/m) | Tensile E-Modulus (GPa) |
|---|---|---|---|---|
| S20/200 | 20 | 200 | 0.52 | 45 |
| S22/240 | 22 | 240 | 0.62 | 45 |
| S25/320 | 25 | 320 | 0.83 | 45 |
| S28/400 | 28 | 400 | 1.04 | 45 |
| S32/500 | 32 | 500 | 1.30 | 45 |
These specifications, including the waved thread structure for better bonding, enable the bolt to perform reliably in drill-and-grout bolt applications, where precise installation is crucial. By comparing it to hollow bar anchors, engineers can appreciate the enhanced durability and reduced maintenance, making it a cost-effective choice for long-term projects.
The SupAnchor GFRP Solid Bolt finds extensive use in diverse geotechnical settings, from stabilizing slopes in mountainous regions to reinforcing underground tunnels and mine roadways. Its corrosion resistance makes it suitable for humid, saline-alkali environments, common in coastal or industrial areas, while its non-magnetic properties ensure safety near power facilities and precision instruments. As a key element in self drilling anchor bolt systems, it integrates seamlessly with existing geotechnical reinforcement systems, offering flexibility for both temporary and permanent support. Notable applications include:
These uses highlight the bolt's adaptability, addressing specific challenges like electromagnetic sensitivity and heavy load demands, which are critical in European and American engineering standards.
The introduction of the GFRP Solid Bolt aligns with global trends in infrastructure development, where there is a growing emphasis on sustainability, safety, and efficiency. In industries like tunneling and mining, this product contributes to reduced environmental impact and lower lifecycle costs, as it minimizes corrosion-related failures and maintenance. SupAnchor's innovation supports broader geotechnical reinforcement systems, enhancing reliability in projects such as highway construction, dam building, and urban development. By offering a lightweight alternative to steel, it also reduces carbon footprints associated with transportation and installation. This advancement not only improves operational safety but also fosters economic benefits by extending the service life of structures, resonating with international efforts to build resilient infrastructure.
