√ Brief Introduction
R51L hollow bolt is one of the R-thread self-drilling hollow injection anchor bolt. It is composed by hollow anchor bar, anchor nut, anchor plate, anchor coupling, drill bit, centralizer, and the hollow anchor bars can be cut and lengthened by coupling on request.
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.
√ Features
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.
