In the challenging geological conditions of European tunneling projects, such as those in the Alps or urban underground expansions, engineers often grapple with rock instability and soft ground. These scenarios demand robust solutions for strata control to ensure safety and efficiency. SupAnchor's new SupShell Expansion Rock Bolt System has emerged as a key player, offering a high-quality self-drilling anchor system designed to tackle these hurdles. By enabling quick assembly and secure installation, this system supports improved advance cycles and fortification, making it a valuable asset in modern infrastructure development.
The SupShell system integrates advanced features to address common engineering challenges. Its design allows for easy and fast installation, with immediate anchorage provided by the expansion shell that generates superior grip. This is particularly beneficial in time-sensitive projects where delays can escalate costs. Key parameters from the product line highlight its adaptability: for instance, the galvanized option under ISO 1461 ensures corrosion protection, extending the system's lifespan in harsh environments. The injection system facilitates efficient grouting, with a plastic sealing element preventing leakage and ensuring complete hole filling, which enhances mechanical and chemical anchorage.
To illustrate the technical specifications, the following table outlines key models and their attributes, demonstrating how they solve engineering challenges by offering tailored solutions for different drill hole diameters and load requirements:
| Expansion Shell Model | Outside Diameter (mm) | Drilling Hole Diameter (mm) | Length (mm) | Weight per Meter (kg/m) |
|---|---|---|---|---|
| R25/EX36 | 36 | Φ40-Φ42 | 132 | 0.62 |
| R28/EX40 | 40 | Φ44-Φ46 | 136 | 0.84 |
| R32/EX44 | 44 | Φ48-Φ50 | 135 | 0.82 |
| R32/EX46 | 46 | Φ50-Φ52 | 176 | 1.2 |
| R32/EX48 | 48 | Φ52-Φ54 | 165 | 1.45 |
These specifications, including thread type ISO 10208 and steel type CK45, ensure compatibility and durability. For example, the varying diameters and lengths allow engineers to select the appropriate model based on soil conditions, reducing installation time and improving savings in workmanship. The self-drilling anchor system's ability to provide both mechanical and chemical anchorage makes it a versatile drill-and-grout bolt, suitable for pre-grouting or post-grouting applications in diverse geotechnical settings.
The SupShell system finds relevance across multiple sectors, from tunneling and mining to slope stabilization and foundation work. In large-scale projects like cross-border railway tunnels or urban metro expansions, the need for reliable geotechnical reinforcement systems is paramount. This hollow bar anchor system addresses that by offering immediate load-bearing capacity, which minimizes downtime and enhances safety. For instance, in mining operations where ground movement is a constant threat, the system's improved fortification cycles help maintain structural integrity, preventing collapses and protecting workers.
Moreover, the system's adaptability to different geological profiles—from soft soils to hard rock—makes it a go-to solution for engineers worldwide. By integrating this self-drilling anchor bolt into their projects, companies can achieve better resource management and cost efficiency, aligning with sustainable development goals. The use of such advanced ground anchor bolt technology underscores the growing emphasis on innovation in construction methodologies.
