Anchors and Rock Bolts R25 to T130 for Self Drilling Hollow Anchor Bolt (R-thread)

IBO Self-drilling Anchors are successfully used for anchoring in poor ground, cohesive and non-cohesive soils, and in the case of unstable boreholes. Main applications are:

• Tunneling and Mining

Rock bolting

Face anchoring

Reinforcement ahead of the tunnel face - spiles

Foot piles

Tunnel portals, trenches, and cut and cover area

• Special foundations

Reinforcement of excavation pits, dams, and slopes - grouted anchors

Anchorage of retaining walls and noise barriers

Pile foundation and buoyancy control - grouted piles

Avalanche protection structures

Anchorage of avalanche barriers

IBO-anchor plate

IBO - drill bits are available both hardened and with carbide inserts. Drill bits in different designs and diameters are available on request.

• Hollow bar anchor with continuous cold-rolled outside-thread
• Application as injection anchor without casing, especially for non-stable boreholes
• Self-drilling installation, utilization of the anchor bar as drill rod with a single-use drill bit
• Easy extension of the anchor bars by couplings
• Grouting or development of the grout body either simultaneously with drilling by using a rotary injection adapter or afterwards
• Assembly of the anchor head with the anchor plate and the nut; stressing and locking of the anchor bar with a torque wrench or hydraulic jack after the grout has cured.

• Easy and similar operating principle for different rock mass and soil conditions
• Drilling, installation, and injection of the IBO anchor in one single operational step
• No pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installation necessary
• Minor space requirement for anchor installation
• Optimized machinery and manpower requirements
• Basic dimensioning of the required anchoring forces by choosing the appropriate anchor type
• Functional adjustment of the required anchor lengths using couplings
• Optimum bonding of the profiled anchor rod and the grout
• Adjustment of the IBO - drill bit design and diameter to different rock mass and ground conditions
• Bare or corrosion-protected version available
• Appropriate for temporary or permanent applications 2), 3)

1) IBO - anchor bars, couplings, nuts, and anchor plates are available bare or galvanized
2) Accreditation as soil nail for permanent applications by the Austrian Federal Ministry of Transport, Innovation and Technology, Vienna, file no.: BMVIT-327.120/0003-II/ST2/2004
3) Accreditation as micropile for permanent applications by the Austrian Federal Ministry of Transport, Innovation and Technology, Vienna, file no.: BMVIT-327.120/0032-II/ST2/2006
4) Special lengths and dimensions available on request.
