In the rugged terrains of hydropower station projects, unstable slopes pose significant risks to infrastructure and safety. SupAnchor's Grade 75 self-drilling hollow anchor bars are increasingly deployed to address these challenges, offering a reliable geotechnical reinforcement system that ensures stability in complex geological conditions. This innovative self drilling anchor bolt technology is gaining traction in European and American markets for its efficiency and adaptability.

At a recent hydropower slope stabilization project in a mountainous region, engineers faced loose rock and soil erosion, requiring rapid installation of anchors to prevent landslides. SupAnchor's hollow bar anchor system was selected for its drill-and-grout bolt capabilities, allowing simultaneous drilling and grouting to save time and reduce costs. The project, spanning over 500 meters of slope, highlighted the system's role in enhancing geotechnical safety and project timelines.
The installation process involves drilling the self drilling anchor system directly into the ground, followed by grouting to secure the structure. This method addresses engineering needs for high bond performance and quick deployment in unstable soils. Key parameters from SupAnchor's product include tensile strength, diameter variations, and corrosion resistance, which collectively solve challenges like poor ground adhesion and long-term durability.
| Property | Value |
| Elongation | ≥ 6% |
| Yield Load | Approx. 147 kN (33 kips) |
| Ultimate Load | Approx. 196 kN (44 kips) |
| Weight | Approx. 2.6 kg/m (1.75 lbs/ft) |
| Thread Orientation | Left-hand thread |
These specifications, such as the high yield load and left-hand thread design, improve bond performance in concrete, reducing the risk of anchor failure. The self drilling anchor bolt's compatibility with existing R and T thread systems ensures seamless integration, minimizing downtime in projects. For instance, in tunneling applications, the hollow bar anchor allows efficient grout flow, enhancing reinforcement in weak rock formations.
By meeting ASTM A615 standards, this geotechnical reinforcement system provides a dependable solution for engineers, emphasizing SupAnchor's commitment to innovation and quality.
Beyond hydropower stations, SupAnchor's self drilling anchor system is vital in tunneling, mining, and foundation reinforcement worldwide. In Europe, urban tunneling projects utilize these bars to stabilize soil and rock, preventing collapses and ensuring worker safety. Similarly, in North American mining operations, the drill-and-grout bolt approach speeds up support installation in unstable shafts, reducing project risks and costs.
The adaptability of the hollow bar anchor makes it suitable for various soil nail system applications, where rapid deployment is crucial. For example, in slope stabilization along highways, these bars have been used to reinforce embankments, demonstrating their market value in enhancing public infrastructure resilience. SupAnchor's products are increasingly specified in international tenders, reflecting their reliability in diverse geological conditions.
The global infrastructure sector benefits from advanced geotechnical reinforcement systems like SupAnchor's, which address growing demands for safety and efficiency in construction.
