Description

28mm Grouting Anchor GFRP Hollow Rock Bolts In Civil Engineering

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. The improved flexibility of long tendons is well suited for application without couplings in confined locations.

Applications

1. Slope stabilization
2. Forepoling
3. Permanent application
4. Stabalization of soft rock

5. TBM face support

Advantages

1. All thread bolt

2. Easy handling due to low weight

3. Flexibility

4. Cuttability

5. High corrosion resistance

6. Good bond force
