The Self Drilling Anchor (SDA) system is a bolting solution for difficult ground and rock conditions. The system enables drilling and grouting in one operation, making much saving in jobsite and project time. Which 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.

Advantages:

1, easy and similar operation principle for different rock mass and soil conditions.

2, drilling, anchoring and grouting can be performed in one single operation.
3, no pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installationnecessary.
4, minor space requirement for the accomplishment of anchoring.
5, optimized machinery and manpower requirements.
6, basic dimensioning of the required anchoring forces by choosing the appropriate anchor type.
7, optimum bonding of the profiled anchor rod and the grout.
8, adjustment of the drill bit design and diameter to different rock mass and ground conditions.
9, simple anti-corrosion method available.
10, appropriate for temporary or permanent applications
