In the realm of geotechnical engineering, projects frequently encounter unstable soils, high structural loads, and challenging environmental conditions that demand robust reinforcement solutions. SupAnchor, recognized as Asia's premier manufacturer and exporter of self-drilling anchors, has launched the SupUTS series, a high-performance self-drilling hollow anchor designed to address these complexities. This innovation promises to enhance safety and efficiency in critical infrastructure developments worldwide, from deep tunnel excavations to coastal defense systems.
The SupUTS self-drilling anchor system integrates a ribbed hollow steel bar that serves as a drill rod, grout injection tube, and reinforcement bar in one unit, streamlining construction processes. This 3-in-1 design eliminates the need for separate equipment, reducing time and risks in unconsolidated or cohesive soils. Key parameters highlight its high-strength performance, with ultimate tensile loads ranging from 360 kN to 930 kN across models, ensuring reliability in high-demand scenarios. The anchor's standardized thread design and compatibility with SupAnchor's accessory system facilitate quick installation, while anti-corrosion options—including hot-dip galvanizing, SupCoating, and stainless steel—extend service life in varied environments.
| Model | Outside Diameter (mm) | Ultimate Load (kN) | Yield Load (kN) | Weight (kg/m) | Anchor Plate Size (mm) |
|---|---|---|---|---|---|
| SSTR32/360 | 32 | ≥360 | ≥280 | 3.5-4.0 | 200 x 200 x 12 |
| SSTR38/660 | 38 | ≥660 | ≥520 | 6.3-6.8 | 250 x 250 x 16 |
| SSTR51/930 | 51 | ≥930 | ≥730 | 9.0-9.5 | 300 x 300 x 20 |
This self-drilling anchor bolt system solves engineering challenges by providing high tensile strength and efficient grouting, which minimizes soil disturbance and ensures structural integrity. The hollow bar anchor design allows for simultaneous drilling and grouting, making it ideal for projects where time and safety are critical.
