25mm Slope Stabilization Fiberglass Hollow GFRP Rock Bolts
Features
The SupFRP® GFRP Hollow Bolt is developed with high tensile load and pressure resistance. 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. The bolts tubes have a high corrosion resistance under acid conditions and are well suited for permanent support.
Applications
1. Slope stabilization
2. TBM face support
3. Stabalization of soft rock
4. Confined ground conditions
5. Forepoling
6. Permanent application
Advantages
1. Cuttability
2. Easy handling due to low weight
3. High tensile load
4. High pressure resistance
5. High corrosion resistance
6. Good bond force
