Anchors, Rock Bolts & Pre-Support

AT – TUBESPILE^™

The AT – TUBESPILE^™ forms part of the POWER SET product family. It qualifies perfectly as a pre-support system in conventional tunneling and is classified as a spile.
The application of the AT – TUBESPILE^™ permits the stabilization of local instabilities in the excavation area and the prevention of ground loosening induced by installation. In poor ground conditions, this system is a sound alternative to conventional ram spiles, rebar spiles, or IBO - Self-Drilling Spiles.

Fields of Application

• Tunneling in soft homogenous or inhomogeneous ground
• Advances through alpine fault zones
• Advances through sedimentary foundation soil or debris
• Advances through blocky rock mass

Main Advantages

• Installation using conventional drill jumbos
• Secure and easy installation procedure
• Spile drilling and installation in one step
• Ground preserving, self-drilling installation
• Higher section modulus than comparable ram spiles, rebar spiles, or IBO - Self-Drilling Spiles
