32mm Epoxy Concrete Anchor Hollow Grouting Threaded Rock Bolts
Features
The SupFRP® GFRP Hollow Bolt is developed with high tensile load and pressure resistance. Due to its high tensile strength the bolt has a high and immediate load bearing capacity if applied with fast setting resin capsules.
It combines rock bolt with injection function. After injection work,the bolt can remain in the borehole and bear load with plate and nut at the end. Due to high injection pressure,it can realize full grouting and improve project quality.
Applications
1. Slope stabilization
2. TBM face support
3. Forepoling
4. Stabalization of soft rock
5. Permanent application
Advantages
1. Easy handling due to low weight
2. High tensile load
3. Cuttability
4. High corrosion resistance
5. Good bond force
