In the demanding environments of soft rock and clay soils, infrastructure projects across Europe and North America face significant geological challenges, including unstable tunnel faces and slope failures. SupAnchor's SupFRP GFRP self drilling anchor system has emerged as a key solution, enabling rapid installation and robust support in applications such as tunneling and slope stabilization. This innovative self drilling anchor bolt combines drilling, grouting, and anchoring into a single process, reducing project timelines and enhancing on-site safety. By addressing common issues like debris accumulation and machinery obstructions, the system supports efficient geotechnical reinforcement in diverse conditions.
The SupFRP GFRP self drilling anchor system features a central hole that allows for water flushing during drilling, which clears debris and facilitates grouting in soft rock or clay soil. This hollow bar anchor design ensures high torque resistance and easy handling, critical for maintaining stability in dynamic geological settings. Key technical parameters, such as guaranteed tensile load and torsion strength, directly address engineering needs by preventing anchor failure and protecting machinery during installation. For instance, the high tensile E-modulus of 45 GPa across models ensures durability under stress, while the cuttability feature avoids damage during tunnel enlargement. Below is a summary of technical data for the H25S, H28S, H32S, and H38S models, highlighting their role in efficient drill-and-grout bolt applications.
| Model | Outside Diameter (mm) | Internal Diameter (mm) | Guaranteed Tensile Load (kN) | Torsion Strength (Nm) | Weight (kg/m) |
|---|---|---|---|---|---|
| H25S | 25 | 12 | 220 | 180 | 0.63 |
| H28S | 28 | 14 | 280 | 250 | 0.86 |
| H32S | 32 | 15 | 365 | 360 | 0.99 |
| H38S | 38 | 20 | 490 | 450 | 1.33 |
These specifications enable the self drilling anchor system to handle high end loading and permanent applications, making it ideal for reinforcing tunnel faces and stabilizing slopes. The ISO standard thread profile ensures compatibility with global equipment, while the lightweight design simplifies logistics and reduces labor costs. By integrating these features, SupAnchor's geotechnical reinforcement system minimizes risks in unstable ground, supporting safer and more efficient construction practices.
The versatility of the self drilling anchor bolt extends to various critical applications, enhancing safety and efficiency in infrastructure projects. Key uses include:
This hollow bar anchor system is particularly effective in projects requiring quick deployment, such as emergency repairs or urban development in geologically sensitive areas. For example, in European tunneling projects, the drill-and-grout bolt has reduced installation time by up to 30%, according to field reports, highlighting its value in time-critical scenarios.
