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. Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micro piles etc jobs, which is widely used in mining, tunneling, railway, metro construction etc projects.

 

R Thread size:R25,R32,R38,R51,

T Thread size: T30, T40, T52, T73, T76,T103, T127, T130.
Thread standard: ISO10208/ISO1720

 

 

Advantages and Characteristics:

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 bond with 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.

7.Duplex anti-crossion prosess ,hot-dip galvanized and epoxy coating system.
