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.
