AT - POWER SET TUBESPILE

Characteristics and Applications

In Tunneling, spiles are generally used for local reinforcement ahead of the tunnel face. The AT - POWER SET TUBESPILE is installed self-drilling in terms of a one-step operation and is suitable for safe and time-optimized excavation in loose rock or soil. Optionally, the TUBESPILE is also available as a vacuum lance system for active ground drainage.

• One-step installation procedure
• Safe and fast installation using standard drilling equipment
• Optimization of the excavation geometry and increased advance per round
• Easy adjustment to changing ground conditions
• Careful ground treatment due to self-drilling installation
• Minimization of overexcavation and additional convergence
• Immediate reinforcement after the TUBESPILE installation is accomplished
• Unproblematic installation in case of unstable boreholes
• Optionally available with perforation holes for drainage or injection purposes
• Higher moment of inertia against bending as comparable rebar or IBO - spiles
