In the demanding world of geotechnical engineering, where unstable rock formations and harsh environmental conditions pose significant challenges, SupAnchor has introduced the SupCT Bolt System, a groundbreaking self-drilling anchor system designed to revolutionize rock support. This innovative product, part of SupAnchor's portfolio of high-quality self-drilling anchor systems manufactured in China, addresses critical needs in applications such as tunneling, mining, and infrastructure development across Europe and North America. The system's ability to provide immediate and permanent support in diverse geological settings highlights its engineering adaptability and market value, positioning it as a key player in enhancing geotechnical safety globally.
The SupCT Bolt System combines advanced materials and design to meet stringent engineering demands. Available in two main categories—Steel Bolt (including solid and hollow bar types) and GFRP Bolt (including solid and hollow bar types)—it offers versatility for various rock support scenarios. Key parameters such as duplex corrosion protection, high tensile strength, and optimized grouting ensure reliable performance. For instance, the Steel Bolt models, like SSB-M20 with a yield load of 157 kN and ultimate load of 186 kN, demonstrate robust pull-out resistance, while GFRP Bolts provide permanent corrosion resistance with ultimate loads up to 560 kN for GSB-R32. These specs solve engineering challenges by reducing installation time, minimizing on-site workload, and ensuring long-term durability, as evidenced by service life ranging from 50 to 150 years.
| Model | Type | Yield Load (kN) | Ultimate Load (kN) | Service Life (years) |
|---|---|---|---|---|
| SSB-M20 | Steel Solid | 157 | 186 | 50-150 |
| GHB-R32 | GFRP Hollow | N/A | 360 | Permanent |
The engineering process involves preassembled components for efficiency, with bolts delivered with zinc-coated expansion shells and protective packaging. The optimized grouting design ensures complete hole filling, while the safe bolt head design prevents mortar leakage, enhancing operator safety. This self-drilling anchor bolt system excels in providing both immediate and permanent support with a single unit, eliminating the need for multiple components and reducing project timelines.
The SupCT Bolt System finds extensive use in critical infrastructure projects, including highway tunnels, mining operations, and slope stabilization. Its high ductility for steel bolts and corrosion resistance for GFRP bolts make it suitable for challenging environments, such as acidic soils or coastal areas. In tunneling, for example, the system's ability to adapt to various ground conditions—with borehole diameters ranging from 45-68 mm and depths adjustable based on bolt length—ensures reliable anchorage even in poor rock quality. This geotechnical reinforcement system contributes to global safety standards by preventing rockfalls and structural failures, thereby reducing risks in industries like construction and energy.
Key advantages include:
These features address common issues in geotechnical projects, such as corrosion degradation and labor-intensive setups, making the system a cost-effective solution for large-scale applications.
