Self-Drilling Anchor System
Request a Quote
Self-drilling anchor can be installed for pre-support, acting as steel structure for load-bearing, or thought it grouting to achieve better geological condition.
Features
- Stable quality;
- Thread is compatible with ISO and other international standards;
- Precision-manufactured anchors with ≤ 0.20 mm tolerance;
- Good toughness, Agt ≥ 10%;
- Premium material and special thread rolling process granting good mechanical performance.
Pre-supporting, micropiling for foundation underpinning, slope anchorage, etc.
- No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes.
- 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.
- Fast drilling and installation, drilling, installation and grouting processes are in a single operation.
- The hollow core not only serves for flushing during drilling, but also for grouting after drilling.
- Continuous threads ensure that the bars can be cut and coupled or extended at any point.
- Different anchor bits are available for different ground conditions.
