In the challenging geological landscapes of Europe and North America, infrastructure projects such as tunnel construction, mining operations, and slope stabilization often grapple with unstable rock formations that demand robust support systems. SupAnchor has stepped up with its SupCT Bolt System, a self drilling anchor system designed to provide reliable, long-lasting solutions. This innovation addresses critical engineering needs by combining high ductility in steel bolts and permanent corrosion resistance in GFRP bolts, ensuring safety and efficiency in diverse applications. The system's adaptability to various ground conditions makes it a go-to choice for geotechnical reinforcement, supporting everything from urban tunneling to remote mining sites.
The SupCT Bolt System is categorized into Steel Bolt and GFRP Bolt types, each with solid and hollow bar variants, tailored for specific rock support scenarios. Key parameters highlight its engineering prowess: for instance, the Steel Solid Bolt model SSB-M20 boasts a yield load of 157 kN and an ultimate load of 186 kN, while the GFRP Solid Bolt model GSB-R25 achieves an ultimate load of 350 kN. These specs ensure strong pull-out resistance and durability, crucial for withstanding dynamic loads in tunneling and mining. The system's duplex corrosion protection—combining hot dip galvanization and epoxy powder coating—extends service life up to 150 years, mitigating common issues like rust in humid or chemically aggressive environments. Additionally, factory preassembly of components like zinc-coated expansion shells streamlines installation, reducing on-site labor and time by up to 30%, which is vital for fast-paced projects. A summary of select models illustrates its versatility:
| Model | Type | Yield Load (kN) | Ultimate Load (kN) | Borehole Diameter (mm) |
|---|---|---|---|---|
| SSB-M20 | Steel Solid | 157 | 186 | 45-48 |
| SHB-R2715 | Steel Hollow | 159 | 191 | 45-48 |
| GSB-R25 | GFRP Solid | N/A | 350 | 45-48 |
This self drilling anchor bolt system solves engineering challenges by providing immediate support upon installation, thanks to its drill-and-grout mechanism that fills boreholes completely, preventing voids and enhancing stability. The optimized grouting design, with a short distance between the grouting pipe end and expansion shell, ensures mortar fills the hole from the bottom up, a key advantage in soft rock conditions where traditional methods may fail. Moreover, the hollow bar anchor variants facilitate efficient grouting in confined spaces, making them ideal for complex geotechnical reinforcement tasks.
The SupCT Bolt System finds extensive use in global infrastructure, including tunneling for transportation networks, slope stabilization in mountainous regions, and support in mining excavations. Its ability to handle varied ground conditions—from soft to hard rock—means it can be deployed in projects like the Eurotunnel or North American mining sites, where safety and longevity are paramount. For example, in tunneling, the system's high efficiency allows for rapid installation without multiple support components, cutting project timelines and costs by an estimated 20%. This geotechnical reinforcement system also contributes to sustainable development by reducing the need for frequent replacements, aligning with environmental goals in construction. The self drilling anchor system's corrosion resistance is particularly valuable in coastal or industrial areas, where saltwater or chemicals accelerate degradation, ensuring structures remain secure for decades.
SupAnchor's commitment to innovation is evident in the SupCT Bolt System, backed by rigorous R&D and adherence to international standards such as ISO, DIN, and ASTM. The company's certifications, including compliance with NS-EN-ISO 1461 for hot dip galvanization and NS-EN 13438 for epoxy coating, underscore its professionalism and reliability. Collaborations with global engineering teams have led to deployments in over 50 countries, enhancing SupAnchor's reputation as a leader in ground anchor bolt manufacturing. The brand's message of being professional, innovative, and collaborative resonates through this product, which has been integral to major projects like urban subway expansions and dam reinforcements. By focusing on continuous improvement, SupAnchor ensures that its self drilling anchor systems meet evolving market demands, solidifying its position in the competitive geotechnical sector.
