In the ever-evolving field of geotechnical engineering, the demand for reliable, high-performance anchoring solutions continues to grow. SupAnchor®, a global leader in ground anchor systems, has unveiled its latest innovation: the SupFRP® GFRP Hollow Injection Bolt. This product integrates the functions of a rock bolt and injection system, offering exceptional tensile load, corrosion resistance, and ease of installation. Designed for challenging ground conditions, the bolt is set to transform slope stabilization, TBM face support, forepoling, and soft rock reinforcement projects worldwide.
The SupFRP® GFRP Hollow Injection Bolt is engineered to meet the rigorous demands of modern construction. Available in multiple diameters and tensile capacities, the bolt ensures optimal performance across a wide range of applications. Below is a summary of key technical specifications:
| Model | Outer Diameter (mm) | Tensile Load (kN) | Pressure Resistance (MPa) | Weight (kg/m) |
|---|---|---|---|---|
| H25/220 | 25 | 220 | 5 | 0.64 |
| H28/320 | 28 | 320 | 5 | 0.88 |
| H32/360 | 32 | 360 | 5 | 1.20 |
| H38/490 | 38 | 490 | 5 | 1.50 |
| H22/230 | 22 | 230 | 18 | 0.58 |
| H25/300 | 25 | 300 | 30 | 0.79 |
The GFRP material offers high tensile load and excellent corrosion resistance, making the self drilling anchor system ideal for permanent applications in aggressive environments. The hollow bar design allows for simultaneous drilling and grouting, improving efficiency and ensuring full grout coverage. With a tensile E-modulus of 45 GPa and ultimate strain of 2.0%, the bolt provides robust support while maintaining ductility. The lightweight construction (as low as 0.58 kg/m) simplifies handling and reduces labor costs on site.
The SupFRP® Hollow Injection Bolt is specifically designed for slope stabilization, TBM face support, forepoling, and stabilization of soft rock. Its high pressure resistance (up to 30 MPa in select models) enables effective grouting in confined ground conditions. For instance, in tunnel construction, the self drilling anchor bolt can be installed quickly to provide immediate face support, minimizing downtime and enhancing safety. The system's cuttability allows for easy length adjustment, accommodating various project requirements.
As global infrastructure investment grows, the need for reliable geotechnical reinforcement systems becomes paramount. SupAnchor's product aligns with the industry's shift toward corrosion-resistant, high-strength materials. The drill-and-grout bolt eliminates the need for separate drilling and grouting operations, reducing project timelines by up to 30%. This efficiency gain is critical for large-scale projects such as highway cuttings, railway embankments, and mining operations.
SupAnchor® continues to lead the soil nail system manufacturer market with a focus on R&D and quality. The company's ISO-certified manufacturing processes ensure consistent product performance. With a global track record of successful projects in Europe, the Americas, and Asia, SupAnchor offers unparalleled expertise in ground anchor bolt factory production. The new GFRP Hollow Injection Bolt reflects the brand's commitment to 'Professional, Innovative, Collaborative' values. By combining cutting-edge materials with practical engineering solutions, SupAnchor empowers contractors to tackle the most demanding geotechnical challenges.
In summary, the SupFRP® GFRP Hollow Injection Bolt is a game-changer for geotechnical engineering. Its advanced specifications, ease of use, and proven reliability make it the preferred choice for engineers seeking long-term stability and cost-effectiveness. As the industry evolves, SupAnchor remains at the forefront, delivering innovative anchoring systems that build a safer, stronger future.
