In challenging tunneling projects across Europe and America, where unconsolidated soils and rock instability pose significant risks, engineers are turning to advanced geotechnical reinforcement systems. SupAnchor, recognized as Asia's leading manufacturer and exporter of self-drilling anchors, has unveiled its T Thread Self-Drilling Hollow Anchor, a core product designed to address these demands with efficiency and reliability. This innovation comes as global infrastructure development accelerates, requiring solutions that minimize construction time while ensuring structural integrity in diverse geological conditions.
The T Thread Self-Drilling Hollow Anchor adheres to the T International Standard, offering a standardized approach that simplifies on-site installation. Its design follows the "3-in-1 principle," where the ribbed hollow steel bar functions as a sacrificial drilling rod, injection tube, and reinforcing bar simultaneously. This integrated system eliminates the need for separate casing, reducing construction time by up to 50% in cohesive soils where traditional methods are time-consuming. Key parameters that enhance performance include optimized rib geometry with a relative rib area (fR) ranging from 0.21 to 0.33, which maximizes bonding with grouting materials, and a 45° rib angle that minimizes splitting forces, keeping crack widths below 0.1 mm under maximum load.
To cater to varied environmental needs, SupAnchor provides three anti-corrosion options: hot-dip galvanizing for general use, SupCoating (HDG + epoxy) for moderately corrosive environments, and stainless steel for highly corrosive scenarios like coastal projects. The product's compatibility with standard rotary percussive drilling equipment and matching accessories ensures seamless integration into existing workflows. Below is a summary of technical data for select models, highlighting the anchor's adaptability:
| Model | Outside Diameter (mm) | Ultimate Load (kN) | Anti-Corrosion Options |
|---|---|---|---|
| T30/16 | 30 | ≥220 | Hot-dip galvanizing, SupCoating, Stainless steel |
| T40/16 | 40 | ≥660 | Hot-dip galvanizing, SupCoating, Stainless steel |
| T76/1400 | 76 | ≥1400 | Hot-dip galvanizing, SupCoating, Stainless steel |
This self drilling anchor system not only improves bonding performance but also addresses common engineering challenges such as soil erosion and load-bearing deficiencies. By incorporating a hollow bar anchor design, it allows for efficient grout injection, enhancing stability in soft or rocky terrains.
The T Thread Self-Drilling Hollow Anchor is widely deployed in critical infrastructure projects. In tunneling engineering, it provides essential support for tunnel faces and surrounding rock reinforcement, preventing collapses during excavation. For slope stabilization, it reinforces natural or man-made slopes along highways and mining sites, resisting landslides and soil erosion. Additionally, it strengthens building foundations and retaining walls in soft soils, improving load-bearing capacity for both permanent structures like bridges and temporary shoring during construction.
This geotechnical reinforcement system aligns with global trends toward sustainable and efficient construction, reducing environmental impact through minimized waste and faster project completion. As urbanization increases, the demand for such innovative solutions grows, particularly in regions prone to geological hazards.
