Introduction Of Hollow Drilling Mining Rock Grouting Anchor Bolt
1, Hollow Drilling Mining Rock Grouting Anchor Bolt consists of hollow core with continuous hot-rolled outside thread
2, Hollow Drilling Mining Rock Grouting Anchor Bolt can application as injection anchor without casing, especially for non-stable boreholes
3, self-drilling installation, utilization of the anchor bar as drill rod with a single-use drill bit
4, easy extension of the anchor bars by anchor coupler
5, grouting or development of the grout body either simultaneously with drilling using a rotary injection adapter or afterwards
6, assembly of the anchor head with the anchor plate and the nut, stressing and locking

 

Features and Advantages

  • Particularly suitable for difficult ground conditions.
  • An efficient installation since drilling, placing and grouting can be performed in a single operation, saving both time and money.
  • Self-drilling system eliminates the requirement for a cased borehole in collapsing soils.
  • Fast, single-step anchoring system with simple equipment able to work with standard track drill (top hammer) or hand-held drilling equipment, eliminating the need for larger casing rigs.
  • Installation with simultaneous drilling and grouting possible, and post grouting system is simple.
  • Continuously drilling and grouting under high pressure causes the grout to permeate into looser soils and creates a bulb-effect for increased bond capacity.
  • Easy installation in all directions, also upwards, and similar installation methods for all ground conditions.
  • Suitable for working in limited space, height and in areas of difficult access.
  • Galvanizing for enhanced corrosion protection is available if necessary.
  • Multiple ranges of drill bits suitable for different ground conditions.
  • Continuously threaded bar pattern can be cut and coupled anywhere along its length to achieve all lengths.
