—Self-drilling Rock Bolt

Rock anchors provide reinforcement and improve shear resistance along unfavorable joints and bending planes. MAXDRILL self-drilling anchor embodies drilling, grouting and anchoring as a whole. Widely used as an efficient anchoring means, in tunnel pre-support, slope stabilization, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sinkage. It’s irreplaceable in narrow construction environment. Small diameter, drilled, grouted in place, anchors incorporating steel reinforcement are used for support of steep rock cuts.

Applications

 

This application is useful for support of steep rock cuts where artificial resistance in the form of a retaining wall is needed to provide reinforcement and ensure safety.

The SupAnchor Self-Drilling Anchor

is a unique anchoring system and is today’s

answer to the increasing demands of the

tunnelling industry and ground engineering for safer and faster production.

The system provides advantages for all areas of its

applications, where boreholes would require the

time consuming drilling with casing systems in

unconsolidated or cohesive soil.

Features and Advantages

• Fits SupAnchor standard Boomer, ROC and

Mustang rigs.

• Particulary suitable for difficult ground conditions.

• A high rate of installation since drilling, placing

and grouting can be performed in one single

operation.

• Self drilling system eliminates the requirement

for a cased borehole.

• Installation with simultaneous drilling and

grouting possible.

• Easy installation in all directions, also upwards.

• Suitable for working in limited space, height and

in areas of difficult access.

• Simple post grouting system.• Hot-dipped galvanizing for corrosion protection
