Threaded Rock Bolt T73/56 Hollow Anchor Self Drilling Rock Anchors for Quarry
Specification:
Outer Diameter:73mm
Inner Diameter:56mm
Utimate Load:1035KN
Yield load:830KN
Weight:10.8kg/meter
Description:
Self drilling anchor system is mainly used in slope stabilization, tunneling pre-support, foundations with micropiles, it is also widely used in the railway system, metro project etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formations. The unconsolidated ground condition favor the self-drilling anchor bolt technique for fast and simple method of installation compared to the traditional method.|
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.
Tunnelling Ground engineering:
1. Face stabilization
2. Radial systematic anchoring
3. Foundation for avalanche protect
4. Stabilization of tunnel portals
