T76 Steel Anchor Bolts / Anchor Rods / Anchor Bar For Micropile Foundation
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.
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
