In the realm of modern geotechnical engineering, the challenges posed by unstable soils, deep excavations, and heavy-duty infrastructure demand innovative solutions. SupAnchor, Asia's leading manufacturer and exporter of self-drilling anchor systems, has responded with the introduction of the SupUTS self-drilling hollow anchor. This high-performance product, part of the SupAnchor® self-drilling anchor system, is engineered to address demanding scenarios requiring superior load-bearing capacity and structural reliability, reinforcing its role in global projects from tunnel support to slope stabilization.
The SupUTS self-drilling hollow anchor is built on a foundation of efficiency and strength, leveraging SupAnchor's expertise in geotechnical reinforcement systems. Its core design features a 3-in-1 integration principle, where a ribbed hollow steel bar serves as a sacrificial drilling rod, injection tube, and reinforcing bar simultaneously. This eliminates the need for separate equipment, streamlining construction processes and reducing risks in unconsolidated or cohesive soils. The "UTS" designation, referencing Ultimate Tensile Strength, indicates optimized tensile and yield load capacities, making it suitable for high-load applications like deep foundation reinforcement and large-scale tunnel support.
Key parameters highlight the product's engineering adaptability. For instance, the model SSTR32/360 offers an ultimate load of ≥360 kN, while SSTR51/930 reaches ≥930 kN, ensuring performance in extreme conditions. Anti-corrosion options, including hot-dip galvanizing, SupCoating (HDG + Epoxy), and stainless steel, extend service life in diverse environments from inland projects to coastal areas. Below is a summary of technical data for key models:
| 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 | 200x200x12 |
| SSTR38/660 | 38 | ≥660 | ≥520 | 6.3-6.8 | 250x250x16 |
| SSTR51/930 | 51 | ≥930 | ≥730 | 9.0-9.5 | 300x300x20 |
This self drilling anchor system emphasizes standardized compatibility, with thread designs aligned to industry norms, ensuring quick installation and reduced labor intensity. The rib structure maximizes bonding with grouting materials, while angled surfaces minimize soil damage, keeping crack widths below 0.1 mm for enhanced stability.
The SupUTS series is tailored for demanding geotechnical reinforcement projects, where its high-strength performance and efficient construction offer significant advantages. Typical applications include:
This hollow bar anchor system addresses critical engineering challenges by combining drill-and-grout bolt functionality with enhanced mechanical properties. For example, in tunnel support scenarios, the SupUTS anchor reduces construction time and improves safety by integrating drilling and grouting into a single step, minimizing disruptions in unstable rock formations.
