Description

R32N Fully Threaded Hollow Grounting Self Drilling Anchor Bolts

The Self Drilling Anchor (SDA) is unique anchoring system and fulfills current and increasing demands of thetunneling 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.

Product Description:

Hollow Drilling Mining Rock Grouting Anchor Bolt consists of hollow core with continuous hot-rolled outside thread. They can application as injection anchor without casing, especially for non-stable boreholes, can be performed in one single operation. no pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installation necessary.

Advantages:

• 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.

• Suitable for working in limited space, height and in areas of difficult access.

• Simple post grouting system.
