The full name of IBO is Injection Bore Micro-Pile System. It used for rocky soils or even solid bedrock. IBO also known as self-drilling anchor system, it utilizes a hollow steel bar with continuously thread. When it drills with the bit, grout is simultaneously injected through the hollow bore.

During the construction of underground works, it is very common to encounter soft rock, fractured zone and large deformation due to high ground stress. In the case of serious collapsing, extra-long anchor is needed instead of ordinary one.

Based on these reasons, IBO self-drilling anchor drilling tools are more and more widely used in underground, support, tunnel and other fields.

IBO Self-drilling anchor embodies drilling, grouting and anchoring as a whole. It widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It’s irreplaceable in narrow construction environment.

The IBO self drilling anchor bolts are fully threaded, hollow core, cold rolled anchors with continuous outside thread suitable for attaching bits and couplings, which also forms a superb mortar connection. They are supplied with couplings, anchor plates and nuts, and anchor drill bit.

IBO Self Drilling Anchors are used for temporary and permanent stabilization; retaining walls in confined spaces; and slope stabilization for roads, railways, and tunnel portals. Whether used in cohesive or non-cohesive ground, the IBO self drilling anchor can be grouted and then stressed and locked off with nut and plate. Advantages are: similar installation for all ground conditions; no casing required; fast drilling and anchoring in a single operation; choice of bits and anchor loads; and hollow core for high-volume flushing and grouting.

Features of IBO self drilling anchor system:

1, High penetrability anchor drill bits, they are very easy to penetrate various rocks.

2,  Self-drilling anchor can be used at the place with narrow space. With continuous thread, achieving the aim of rock reinforcement with extra-long anchor

3, Unnecessary to be pulled out. Hollow steel can be used as grouting channel;

4, Embodies drilling, grouting and anchoring in one step.
