Product Description
Hollow anchor bar means a rod that transfers the structures or geotechnical load to a stable rock formations, anchor bolt consists of bar, drill bit, coupling, plate, grouting stopper and nut. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It's irreplaceable in narrow construction environment. Hollow anchor bar is made of seamless tube with high strength.
Features of Hollow Grouting Anchor Bar:
• Fits standard Boomer, ROC and Mustang rigs.
• Particularly suitable for difficult ground conditions.
• A high rate of installation since drilling, placing and grouting can be performed in one single operation.
• Self drilling system eliminates the requirement for a cased borehole.
• Installation with simultaneous drilling and grouting possible.
• Easy installation in all directions, also upwards.
• Suitable for working in limited space, height and in areas of difficult access.
• Simple post grouting system.
• Hot-dipped galvanizing for corrosion protection
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.

We have products of different specifications in stock, and can customize products of different specifications according to your requirements.
Hollow anchors can be used in the fields of water conservancy engineering, tunnel reinforcement, subway, mine support, and construction.
During the constructions of underground works, it is very common to encounter soft rock, fractured zone and large deformation due to high ground stress. In the case of serious collapsing, extra-long anchor is needed instead of ordinary one.
Technology ProcessThe 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 projects.
1. Connect the alloy drill and anchor rod one end, on the other end, connect the drill sleeve and shank adapter, then connect the drilling rig or hand-held drill. Then start drilling, fill the cooling water while drilling.( If you want to lengthen the anchor rod, can connect the coupling, and then drilling)
2. Take down the drill, put the stop-grouting plug into the rod, and insert it to the hole, then ready to grout. Special circumstances like surrounding rock grouting tension is over or surrounding rock is too broken, can use anchor agent to seal the hole.
3. Connect quick grouting coupling and anchor rod end, connect other end of grouting machine.
4. Start grouting, when grouting full and reach design value then power off. Grouting pressure according to the design parameters and grouting machine performance determine, Cement/sand reference values is 1:0 ~ 1:1, water/cement reference value is 0.45:1 ~ 0.5:1.
5. Install anchor plate and nuts, and tighten nuts. | Packaging and Transportation |
The packaging is packaged in tarpaulins and wooden boxes to ensure that it will not rust and corrode in the process of encountering water.
