In response to growing demands for robust infrastructure solutions, SupAnchor, Asia's top manufacturer and exporter of self-drilling anchors, has unveiled the Grade 75 Self-Drilling Hollow Anchor. This high-strength variant is engineered to tackle complex geotechnical challenges, such as unstable soils and heavy-load scenarios, by combining superior load-bearing capacity with efficient installation processes. As global infrastructure projects increasingly require reliable reinforcement systems, this innovation underscores SupAnchor's commitment to advancing geotechnical engineering through professional and innovative approaches.
The Grade 75 self-drilling hollow anchor is built on SupAnchor's core "3-in-1 principle," which integrates a sacrificial drilling rod, injection tube, and reinforcing bar into a single high-strength steel unit. This design enables simultaneous drilling and grouting, significantly improving construction efficiency in unconsolidated or cohesive soils where traditional methods are inefficient. Key technical features include the use of Grade 75 high-strength steel, which provides enhanced ultimate and yield loads compared to standard grades, ensuring stability under extreme tensile and shear forces. The anchor's standardized thread design, compliant with ISO 10208/ISO 1720, allows for quick on-site connections, while its rib structure optimizes bonding with grouting materials and minimizes soil disruption.
To illustrate the product's capabilities, here are inferred technical parameters based on SupAnchor's product line logic, showcasing how this self drilling anchor system addresses engineering needs:
| Parameter | Grade 75 R32 Model | Grade 75 R38 Model |
|---|---|---|
| Outside Diameter (mm) | 32 | 38 |
| Internal Diameter (mm) | 18-20 | 19-21 |
| Cross-Sectional Area (mm²) | 400-450 | 600-650 |
| Ultimate Load (kN) | ≥380-420 | ≥550-600 |
| Yield Load (kN) | ≥300-340 | ≥440-480 |
| Weight (kg/m) | 3.2-3.6 | 4.7-5.1 |
| Thread Type | ISO 10208 - R32 | ISO 10208 - R38 |
| Steel Type | Grade 75 High-Strength | Grade 75 High-Strength |
These specifications enable the hollow bar anchor to resist high pressures and deformations, making it ideal for projects where standard anchors fall short. For instance, the drill-and-grout bolt functionality reduces labor intensity and construction delays, aligning with modern engineering demands for speed and reliability.
The Grade 75 self-drilling anchor bolt is tailored for a range of demanding applications, highlighting its adaptability in geotechnical reinforcement systems. Key scenarios include:
These applications demonstrate how the self drilling anchor system enhances geotechnical safety by providing a reliable load-bearing solution, even in soft soils or under heavy structural demands.
