Description

25mm-130mm Diameter Self Drilling Anchor Bolt Hollow Anchor Bar Anchor Rods for Mining

Production:

The self-drilling hollow bar anchor system consists of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplings can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.

Self-drilling hollow bar anchor system is the most common used system for rock mass stabilization, especially in tunneling, underground mining and ground engineering industry. It is mainly used for the supporting engineering in the loose and broken rock stratal with difficult to drilling hole. It provides the optimal solution for soil nailing, lock bolting, micro-piling.
