Hollow Anchor Bar
Full threaded steel self drilling rock bolt / Hollow anchor bar / Anchor rods
The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. 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. Hollow anchor bar is made of seamless tube with high strength.
Advantages and Characteristics as below:
1. No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes.
2. Fast drilling and installation, because drilling, installation and grouting are in a single operation.
3. Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of bondwith the borehole gout.
4. The hollow core not only serves for flushing during drilling, but also for grouting after drilling.
5. Continuous threads ensure the bars can be cut and coupled at any point, or extended.
6. Different anchor bits are available for different ground conditions.
