In the demanding fields of civil engineering and construction, projects in soft rock and clay soil often grapple with instability during tunneling and slope work. SupAnchor's introduction of the GFRP SDA Bolt marks a significant advancement, providing a unified solution that combines drilling, grouting, and anchoring. This self drilling anchor system addresses critical challenges such as time-consuming installations and machinery damage, enabling faster, safer operations in environments like tunnel face stabilization and slope reinforcement. By leveraging innovative design, SupAnchor enhances project efficiency and safety, catering to the growing needs of global infrastructure development.
The SupAnchor GFRP SDA Bolt stands out with its integrated approach, offering numerous benefits for geotechnical applications. Its design ensures permanent application, high torque resistance, and ease of handling, making it a reliable choice for various soil and rock conditions. Key advantages include:
These features make the hollow bar anchor ideal for reducing project timelines and minimizing risks in challenging terrains.
The technical specifications of the SupAnchor GFRP SDA Bolt are tailored to meet rigorous engineering demands. Below is a detailed table summarizing key parameters for different variants, highlighting how they address common challenges like load-bearing capacity and installation efficiency. The data underscores the product's ability to provide secure anchoring in soft rock and clay soil, with high tensile and torsion strengths ensuring durability under stress.
| Parameter | H25S | H28S | H32S | H38S |
|---|---|---|---|---|
| Outside Diameter (mm) | 25 | 28 | 32 | 38 |
| Internal Diameter (mm) | 12 | 14 | 15 | 20 |
| Guaranteed Tensile Load (kN) | 220 | 280 | 365 | 490 |
| Torsion Strength (Nm) | 180 | 250 | 360 | 450 |
| Weight (kg/m) | 0.63 | 0.86 | 0.99 | 1.33 |
For instance, the high guaranteed tensile load—ranging from 220 kN to 490 kN across models—ensures reliable support in slope stabilization, while the torsion strength protects machinery during drilling. The central hole design allows for water flushing, preventing obstructions and enhancing safety in tunnel enlargements. This drill-and-grout bolt simplifies processes, reducing labor and material costs in geotechnical reinforcement systems.
The versatility of the self drilling anchor bolt extends to various critical applications. In face stabilization for tunnels, it provides immediate support during excavation, minimizing collapse risks. For forepoling and slope stabilization, the bolt's high end loading and easy installation make it suitable for precarious terrains. In soft rock ground support, its cuttability feature safeguards equipment, while in roof and wall bolting, it ensures long-term integrity. These applications highlight how the geotechnical reinforcement system adapts to diverse project needs, from urban infrastructure to mining operations, improving overall safety and efficiency.
