R32S T-thread Self Drilling Bolts with Bolt / Plate / Coupling / Bit / Nut

Products information

The SelfDrilling Anchor (SDA) is unique anchoring system and fulfills current and increasing demands ofthetunneling 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 of hollow grounting anchor bolt

• Particularly 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 in Tunneling & Ground Engineering

• Radial bolting

• Slope stabilization

• Forepoling

• Micro injection pile

• Face stabilization

• Temporary support anchor

• Portal preparation

• Soil nailing
