SOLLROC self-drilling anchor bolts have a wide range of application fields including:
- Reinforcement of poor rock/soil conditions in tunnels,
- Stabilization of tunnel faces
- Tunnel root piling and
- Tunnel entrances.
Self drilling anchor bolt is extensive applied in all kinds of constructions, such as railway system, metro project and infrastructure development. As an efficient anchoring method, it’s also widely applied to pre-support project, radial support project, slope stabilization, foundation support project, soil nail wall, back pull anchor rod retaining wall and other rock supporting work.
R32N Self drilling grouting bolts
1-. Anchor bolt
It has the international standard wave-shape connecting a thread and is very easy to be installed with bit, coupling and fasten a nut. It can also be cut or connected very freely.
To bear higher stress of surrounding rock.
To transmit the stress of surrounding rock to a plate.
It can realize the purpose of elongating to the designed depth while drilling.
It has strong ability of penetrating, so the anchor can pass through various rocks with it.
Max tensile load(KW):280kN
Cross bit all steel(EX)
Cross bit with carbide(EXX)
Clay bit (EW)
