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.
A recent infrastructure project utilized SupAnchor's self drilling anchor system to overcome complex geological conditions, highlighting the technical advantages of hollow bar anchors in geotechnical reinforcement.
SupAnchor introduces the T Thread self-drilling hollow anchor, a drill-and-grout bolt system for tunneling and slope stabilization, with high load capacity and corrosion protection.
A major highway tunnel portal in the European Alps relies on SupAnchor self drilling anchor bolts to overcome fractured rock and water ingress, delivering rapid, reliable ground stabilization and showcasing advanced geotechnical reinforcement systems.
SupAnchor introduces SupShell Expansion Rock Bolt System, a drill-and-grout bolt for immediate anchorage in tunneling, mining, and slope stabilization. Features EN 10083 steel, ISO 1461 galvanizing, and versatile grouting.
SupAnchor's hollow bar anchor technology stabilizes a critical slope with micropile anchors, overcoming fractured rock and groundwater challenges.
