SDA hollow drilling rock anchor bolts & reinforcing steel bars  

The SupAnchor steel self-drilling anchor bolt

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

 Applications

Tunnelling Ground engineering

• Radial bolting • Slope stabilization

• Forepoling • Micro injection pile

• Face stabilization • Temporary support anchor

• Portal preparation • Soil nailing
