Self Drilling Anchor Coupling Sleeve R51 180mm length for Tunnelling Ground engineering
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

| In a certain range, tensile strength increases in proportion to hardness. For couplers or nuts, it's important to make sure the fitting capacity with bars must reach bar's capacity itself. Through hundreds of rounds of testing, SupAnchor sets up a lab standard which is HRC 23 – 30 for couplers and HRC 25 – 30 for nuts. SupAnchor's products have achieved 100% safe application over 15 years. | ||
