Self Drilling anchor bar uses a hollow thread bar with a sacrificial drill bit which is drilled into the ground using grout as a flushing medium. This results in a grout body within the ground containing a high tensile steel bar. Corrosion is taken into account by typically over-specifying the bar with a sacrificial corrosion allowance and/or by the use of special coatings.

We,Sinorock,can offer a design service for all types of self drilling anchor system (rock bolts and soil nails) including; High Capacity Strand anchors, Bar anchors and Hollow threadbar anchors.

Bar Anchors are suitable for loads up to 2000 kN where strand anchors cannot be used. We have designed many schemes using bar anchors from retaining structures to tank farms and continue to offer a design service for this type of anchor.
