Hollow Bar, Soil Nails, Micropiles and Anchors

CTS®/IBO® hollow bars are manufactured from high yield micro alloy steel tubing. CTS®/IBO® hollow bars are installed using the injection bored method, which involves pumping at pressure a cementious grout while the CTS®/IBO® hollow bar is drilled into the grout. This method has many geotechnical benefits and it improves a project’s overall efficiency.
 

Features

• Uses CTS®/IBO® hollow bar as drill steel, grouting conduit and steel reinforcement element
• Threads are formed much like the ribs on a reinforcing bar and are fabricated to ASTM A-615 standards
• The surrounding grout cover acts as corrosion protection
• Additional methods of corrosion protection can be applied such as metallizing, besides sacrificial steel allowance
• Continuous threads guarantee the CTS®/IBO® hollow bar can be cut or coupled anywhere along its length
• Available in various sizes to accommodate loading requirements

 

Advantages

• Fast one-step installation
• Simultaneous drilling and grouting
• Allows the use of smaller equipment at lower cost
• Allows low overhead, limited access installation
• Improves the ground (densification)
• Offers higher skin friction
• Total single corrosion protection by design

Applications

CTS®/IBO® hollow bar anchors are ideal for micropiles, soil nails, tie down and tie back anchors in difficult ground conditions like weathered and decomposed rock, gravel, sand and clay soils for either permanent or temporary use.
