Self-drilling hollow anchor system has been used widely as a new technology for slope stabilization.
Self-drilling hollow bar is full threaded, in which system coupler is used to increase the length, and drill bit with different design for different stratum is installed in the front end as drilling forward, with following advantages:
- Highly increased drilling and installation efficiency. Labor cost saved huge.
- Excellent adaption to difficult rock foundation.
SupAnchor R38N self-drilling hollow anchor system was safely installed in False Creek Project in Vancouver, Canada, in 2015.
The Brenner Base Tunnel project in the Alps employed SupAnchor's self drilling anchor bolts to overcome fractured rock and water inflows, demonstrating the value of advanced geotechnical reinforcement systems.
SupAnchor's T thread self-drilling hollow anchor system integrates drilling, grouting, and reinforcement in one step, delivering high load capacity and corrosion resistance for tunnels, slopes, and foundations worldwide.
A major infrastructure project in the Alps successfully utilized SupAnchor's self-drilling anchor system to overcome fractured rock conditions, enhancing geotechnical safety and project efficiency.
SupAnchor launches a high-performance GFRP hollow injection bolt combining rock bolting and grouting, offering superior tensile load, pressure resistance, and corrosion protection for challenging geotechnical projects.
SupAnchor's self-drilling anchor system is being used in a critical slope stabilization project on a major Alpine highway expansion, overcoming difficult geology and ensuring long-term safety and infrastructure resilience.
