As global infrastructure demands escalate, particularly in Europe and North America, engineers face increasing challenges from unstable soils and high-load requirements. SupAnchor, recognized as Asia's No.1 manufacturer and exporter of self-drilling anchors, has responded with the launch of the SupUTS self-drilling hollow anchor. This high-performance product is designed to address complex geotechnical scenarios, offering superior structural reliability and streamlined construction processes. In projects ranging from deep foundation work to tunnel support, the SupUTS series exemplifies innovation in the self drilling anchor system market.
The SupUTS self-drilling anchor bolt integrates a ribbed hollow steel bar that functions as a drilling rod, injection tube, and reinforcing bar in one—a 3-in-1 design that eliminates the need for separate equipment. This geotechnical reinforcement system is optimized for high-strength performance, with the "UTS" designation referencing ultimate tensile strength. Key parameters include enhanced load capacities, standardized compatibility, and flexible anti-corrosion options. Below is a summary of technical data for key models:
| Model | Outside Diameter (mm) | Ultimate Load (kN) | Yield Load (kN) | Weight (kg/m) | Anti-Corrosion Options |
|---|---|---|---|---|---|
| SSTR32/360 | 32 | ≥360 | ≥280 | 3.5-4.0 | Hot-dip galvanizing, SupCoating, Stainless steel |
| SSTR38/660 | 38 | ≥660 | ≥520 | 6.3-6.8 | Hot-dip galvanizing, SupCoating, Stainless steel |
| SSTR51/930 | 51 | ≥930 | ≥730 | 9.0-9.5 | Hot-dip galvanizing, SupCoating, Stainless steel |
This hollow bar anchor system solves engineering challenges by reducing construction time and labor intensity. For instance, in cohesive soils, the drill-and-grout bolt process ensures efficient grouting and bonding, with rib structures minimizing soil disturbance. The high tensile strength—evident in models like SSTR51/930 with ≥930 kN ultimate load—makes it suitable for extreme conditions where traditional anchors fall short. SupAnchor's standardized design ensures accessory compatibility, further enhancing on-site efficiency.
The SupUTS series is engineered for a wide range of demanding applications. Key scenarios include:
