Description:

1.    Self-drillinganchor bolts

The  Self Drilling Anchor Bolts is aunique anchoring systems and is today''s answer to the increasingdemands of the tunnelling industry and ground engineering for saferand faster production.
The system provides advantages for all areas of its applications,where boreholes would require the time consuming drilling withcasing systems
in unconsolidated or cohesive soil.

Features and Advantages:
-     Particulary suitable difficultground conditions
-     A high rate of installationsince drilling, placing and grouting can be performed inone single operation.
-     Self drilling system eliminatesthe requirement for a cased borehole

Applications:

1).Tunnelling:
-     Radial bolting
-     Forepoling
-     Face stabilization
-     Portal preparation

2).Ground engineering:
-     Slope stabilization
-     Micro injection pile
-     Temporary support anchor
-     Soil nailing
