In the face of escalating infrastructure demands, from urban tunneling expansions to coastal slope stabilizations, the construction industry is increasingly reliant on advanced geotechnical solutions. SupAnchor, recognized as Asia's leading manufacturer and exporter of self-drilling anchors, has launched its T thread self-drilling hollow anchor, designed to meet the rigorous challenges of diverse soil and rock conditions worldwide. Adhering to the T International Standard, this product underscores SupAnchor's commitment to innovation and quality in the geotechnical reinforcement system market.
The T thread self-drilling hollow anchor operates on a "3-in-1 principle," where the ribbed hollow steel bar functions simultaneously as a sacrificial drilling rod, injection tube, and reinforcing bar. This integrated approach enables drilling and grouting in a single operation, eliminating the need for separate casing systems and significantly reducing construction time, particularly in unconsolidated or cohesive soils. Key technical features include optimized thread design for compatibility with standard rotary percussive equipment, a relative rib area (fR) ranging from 0.21 to 0.33 to maximize bonding with grouting materials, and 45° angled rib surfaces that minimize splitting forces, ensuring structural stability with crack widths below 0.1 mm at maximum load.
To illustrate the adaptability of this self drilling anchor system, below is a summary of key specifications for selected models:
| Model | Outside Diameter (mm) | Internal Diameter (mm) | Ultimate Load (kN) | Weight (kg/m) | Typical Lengths (m) |
|---|---|---|---|---|---|
| T30/16 | 30 | 16 | ≥220 | 2.70 | 2, 3, 4 |
| T40/16 | 40 | 16 | ≥660 | 7.17 | 2, 3, 4, 5, 6 |
| T76/1400 | 76 | Varies | High capacity | Varies | Customizable |
Anti-corrosion options further enhance durability, with choices including hot-dip galvanizing for general environments, SupCoating (HDG + epoxy) for moderate corrosion resistance, and stainless steel for extreme conditions like coastal or chemical plant projects. This flexibility ensures the hollow bar anchor can be tailored to specific environmental needs, extending service life and reducing maintenance costs.
The versatility of this geotechnical reinforcement system is demonstrated in its broad applications across global projects. Key scenarios include:
SupAnchor's focus on research and development has solidified its position as a key player in the global infrastructure sector.
