In the demanding fields of tunneling and mining, geological instability poses significant challenges to project safety and timelines. SupAnchor's SupShell Expansion Rock Bolt System addresses these issues with innovative design, providing robust strata control and enhancing efficiency on construction sites worldwide. This self drilling anchor system is engineered to meet the highest quality standards, ensuring reliability in various geotechnical conditions.
The SupShell system features multiple models tailored to specific drilling requirements, enabling easy and fast installation. Key parameters include outside diameter, drilling hole diameter, length, and weight per meter, which are critical for ensuring compatibility and performance. For instance, the expansion shell models such as R25/EX36 and R32/EX48 are designed to deliver immediate anchorage, reducing advance cycles and improving fortification in unstable strata. The grouting system facilitates complete hole filling, preventing leaks and enhancing chemical bond, which is essential for long-term stability.
| Model | Specification | 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 ensure that the self drilling anchor bolts can be deployed quickly, with thread type ISO 10208 and steel type CK45 providing durability and ease of use. The system's ability to offer both mechanical and chemical anchorage makes it a versatile solution for geotechnical reinforcement, solving engineering challenges such as time savings and improved safety.
The SupShell expansion rock bolt system is ideally suited for applications in tunneling, mining, and slope stabilization. Its design allows for pre-grouting or post-grouting, adapting to various geological conditions. For example, in mining operations, the immediate anchorage feature reduces downtime and enhances worker safety, while in tunneling projects, the hollow bar anchor design facilitates efficient grouting, ensuring complete strata support.
This geotechnical reinforcement system plays a vital role in global infrastructure development, contributing to safer and more efficient projects in sectors like transportation and energy. By improving advance cycles and reducing labor costs, the SupShell system supports sustainable development and meets the growing demand for reliable ground anchor solutions. Its adoption in international projects underscores its value in enhancing geotechnical safety worldwide.
SupAnchor demonstrates its commitment to professionalism and innovation through continuous R&D and adherence to standards such as EN 10083 and ISO 1461 for corrosion protection. As a leading soil nail system manufacturer, the company collaborates with global partners to deliver high-quality products, reinforcing its reputation for reliability and excellence in the geotechnical industry.
