In the rugged terrain of the Swiss Alps, the expansion of the Gotthard Base Tunnel presents formidable geotechnical challenges, including unstable rock strata and high hydrostatic pressures. SupAnchor's self drilling anchor system has been deployed to provide robust foundation support, ensuring the tunnel's structural integrity and worker safety. This project underscores the growing reliance on advanced geotechnical reinforcement systems in modern infrastructure.
At the construction site, workers utilize SupAnchor's self drilling anchor bolt to drill through complex geological formations, with the hollow bar anchor design enabling simultaneous drilling and grouting for efficient installation. Key product parameters include:
| Parameter | Value |
|---|---|
| Tensile Strength | 550 MPa |
| Diameter | 32 mm |
| Length | Up to 12 meters |
| Corrosion Protection | Hot-dip Galvanized |
These specifications allow the drill-and-grout bolt to address site-specific issues like rock fracturing and water ingress, enhancing the ground stabilization anchor system's effectiveness. For instance, the high tensile strength ensures long-term durability in dynamic loading conditions, while the corrosion protection extends service life in humid environments.
The adoption of SupAnchor's geotechnical reinforcement system aligns with global trends in infrastructure development, particularly in tunneling and transportation projects. As urbanization accelerates, the demand for reliable soil nail systems and rock bolts for underground mining increases, driven by needs for safety and sustainability. This project highlights how self drilling anchors for retaining walls contribute to slope stabilization in highway and rail networks, reducing risks of landslides and ensuring public safety.
Moreover, the use of micropile hollow bar anchors in such projects supports resilient infrastructure, catering to climate adaptation strategies in Europe and North America.
