R thread self drilling hollow bar anchor is composed by hollow anchor bolt, anchor nut, anchor plate, anchor coupler, drill bit, centralizer, and the hollow anchor bars can be cut and lengthened by coupling on request. Functions: R thread self drilling hollow bar anchor is an advanced system which can ensure the anchoring effect for complex ground conditions. It can be integrated with the functions of drilling, grouting and anchoring. Conditions: Tunneling Mining Slope Stabilization Foundation Support Features and advantages: 1. Safe, reliable, and time saving. 2. Simple installation & operation. 3. Choice of drill bits for different ground conditions. 4. Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively. 5. Anchor bars can be cut and lengthened on request, applying to narrow spaces. 6. It provides higher bonding stress than smooth steel pipe depending on continuous wave thread.
R51l/1R51lR51n/1R51n Self drilling anchoring system is an advanced system which can ensure the anchoring effect for complex ground conditions. It can be integrated with the functions of drilling, grouting and anchoring.

The SupAnchor Self-Drilling Anchor is a unique anchoring system and is todayÂë answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil. Features and Advantages Fits SupAnchor standard Boomer, ROC and Mustang rigs. Particulary suitable for difficult ground conditions. A high rate of installation since drilling, placing and grouting can be performed in one single operation. Self drilling system eliminates the requirement for a cased borehole. Installation with simultaneous drilling and grouting possible. Easy installation in all directions, also upwards. Suitable for working in limited space, height and in areas of difficult access. Simple post grouting system.
