In the complex geological landscapes of Europe and North America, tunneling and mining projects often face significant challenges from unstable rock masses, requiring immediate and reliable reinforcement solutions. SupAnchor, a prominent manufacturer of high-quality self drilling anchor systems, has developed the SupHulk friction rock bolt system to address these needs, providing robust support that enhances safety and efficiency in critical infrastructure development. This innovation is part of SupAnchor's commitment to delivering professional, innovative, and collaborative geotechnical solutions worldwide.
The SupHulk friction rock bolt system, particularly the Premium line (PM) series, is engineered for tunneling and mining applications where stiff support with high yield loads is essential. The installation process is straightforward: operators drill a hole, insert the bolt, and inflate it using a specialized system that automatically stops at the recommended pressure, ensuring consistent quality. This self drilling anchor bolt system immediately bears full loads and absorbs rock movements, distributing forces along the entire bolt length for superior stability.
Key parameters from the PM series highlight its engineering prowess. For instance, the minimum breaking loads range from 110 kN for PM12 to 240 kN for PM24, with minimum yield loads of 100 kN, 130 kN, and 200 kN respectively. All models feature a minimum elongation of 10%, ensuring good deformability under stress. The inflation water pressures are set at 300 bar for PM12 and PM24, and 240 bar for PM16, tailored to different rock conditions. These specifications enable the SupHulk system to solve engineering challenges such as shear movements and irregular boreholes, making it a versatile geotechnical reinforcement system.
| Model | Min Breaking Load (kN) | Min Yield Load (kN) | Min Elongation (%) | Inflation Pressure (bar) | Hole Diameter (mm) |
|---|---|---|---|---|---|
| PM12 | 110 | 100 | 10 | 300 | 32-39 |
| PM16 | 160 | 130 | 10 | 240 | 43-52 |
| PM24 | 240 | 200 | 10 | 300 | 43-52 |
The SupHulk system's ability to form friction and interlocking anchors along the borehole length provides full-column support, adapting to a wide range of rock conditions. Features such as the SupHulk net washer for screening, gap-bridging capabilities, and shear movement tolerance in medium to soft rocks enhance its performance. Notably, a 50 cm inflated bolt can generate 100 kN of friction, offering significant holding power. This makes it an ideal drill-and-grout bolt alternative for rapid, safe installations.
SupHulk rock bolts are highly versatile, finding applications in both tunneling and mining sectors. In tunneling, they serve as pattern bolts to support excavations, with bolting patterns tailored to rock mass properties and project scale. For mining, common uses include roof bolting and hanging wall bolting, where the system's rapid deployment and high performance improve safety and operational efficiency. The capacity ranges of 110 kN to 240 kN ensure suitability for most reinforcement tasks, from small-scale civil engineering to large infrastructure projects.
This adaptability positions the SupHulk system as a critical component in projects across Europe and America, where stringent safety standards and environmental considerations demand reliable geotechnical reinforcement systems.
The SupHulk friction rock bolt system contributes significantly to global infrastructure safety by reducing risks in tunneling and mining operations. Its engineering adaptability and immediate load-bearing capabilities align with industry trends toward faster, safer construction methods.
