Hollow anchor bar means a rod that transfers the structures or geotechnical load to a stable rock formations, anchor bolt consists of rod, 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
