In the demanding world of tunneling and ground engineering, efficiency and safety are paramount. SupAnchor®, a leading manufacturer of geotechnical reinforcement systems, has introduced its R thread self-drilling hollow anchor, a solution designed to streamline operations in challenging soil conditions. With over 39,000,000 meters of self-drilling anchor bars successfully installed globally, the R thread product line represents a significant advancement in the industry.
The R thread self-drilling hollow anchor embodies the '3-in-1 principle,' acting as a sacrificial drilling rod, injection tube, and reinforcing bar. This design allows for drilling and grouting in a single operation, significantly reducing construction time and labor intensity. The system complies with ISO 10208 and ISO 1720 standards, ensuring quick on-site connection and installation.
SupAnchor offers a range of models to suit various project requirements. Below are key specifications for select models:
| Model | Outside Diameter (mm) | Internal Diameter (mm) | Ultimate Load (kN) | Yield Load (kN) | Weight (kg/m) |
|---|---|---|---|---|---|
| R25N/12 | 25 | 12 | ≥200 | ≥150 | 2.30 |
| R32L/22 | 32 | 22 | ≥250 | ≥200 | 2.75 |
| R32SS/15 | 32 | 14 | ≥405 | ≥300 | 4.00 |
The self drilling anchor system is particularly effective in unconsolidated or cohesive soil, where traditional casing systems are time-consuming. By combining drilling and grouting, the R thread anchor minimizes setup time and enhances safety in tunnel face support, forepoling, and slope stabilization.
SupAnchor's R thread anchors are widely used in tunneling, ground engineering, and other geotechnical projects. They provide reliable support for tunnel faces, retaining walls, and foundation reinforcement. To accommodate different environmental conditions, three anti-corrosion options are available:
This versatility ensures the hollow bar anchor maintains long-term performance in diverse climates, from European tunnels to Middle Eastern infrastructure projects.
Global infrastructure development demands efficient geotechnical reinforcement systems. The R thread anchor's drill-and-grout bolt technology reduces project timelines and labor costs, addressing critical challenges in urban tunneling and slope protection. As a soil nail system manufacturer and ground anchor bolt factory, SupAnchor's commitment to ISO-certified production ensures consistent quality across its product line.
With 39 million meters of self drilling anchor bars installed, the company's expertise is evident. The R thread series, including additional models like R38N and R51, offers engineers a wide selection to meet specific load and diameter requirements.
SupAnchor continues to invest in R&D, advancing the design of self drilling anchor systems. The R thread product line exemplifies the company's professional, innovative, and collaborative approach. By providing customizable solutions and responsive technical support, SupAnchor partners with contractors worldwide to enhance construction safety and efficiency.
