In the demanding fields of tunneling and ground engineering, where unstable soil and rock conditions pose significant challenges, SupAnchor has launched its latest innovation: the T thread self-drilling hollow anchor. This product, designed in compliance with international standards, addresses the need for rapid, reliable anchoring solutions in projects ranging from urban infrastructure to remote mining operations. As a leader in Asia's self-drilling anchor market, SupAnchor continues to push the boundaries of efficiency and safety.
The T thread self-drilling hollow anchor system integrates drilling, grouting, and reinforcement into a single operation, significantly reducing construction time and costs. Key features include the 3-in-1 principle, where the hollow bar acts as a drilling rod, injection tube, and reinforcing bar simultaneously. This is particularly beneficial in cohesive or unconsolidated soils, where traditional methods are slow and prone to failure. The optimized rib design, with a relative rib area between 0.21 and 0.33, ensures strong bonding with grouting materials, while the 45° rib angle minimizes splitting forces, keeping crack widths below 0.1 mm at maximum load for enhanced stability.
To meet diverse engineering needs, SupAnchor offers various anti-corrosion treatments: hot-dip galvanizing for general environments, SupCoating for moderate corrosion resistance, and stainless steel for highly corrosive conditions like coastal areas. This adaptability extends the product's service life and applicability across global projects.
| Model | Outside Diameter (mm) | Internal Diameter (mm) | Ultimate Load (kN) | Weight (kg/m) |
|---|---|---|---|---|
| T30/16 | 30 | 16 | ≥220 | 2.70 |
| T40/16 | 40 | 16 | ≥660 | 7.17 |
These specifications enable the self drilling anchor bolt to handle high loads efficiently, solving common engineering challenges such as soil instability and the need for quick installation in time-sensitive projects.
The T thread self-drilling hollow anchor is widely used in critical applications. In tunneling engineering, it provides essential support for tunnel faces and surrounding rock, preventing collapses during excavation. For slope stabilization, it reinforces natural or man-made slopes, reducing the risk of landslides in areas like highway embankments or mining sites. Additionally, it enhances foundation and retaining structures in soft soils, improving load-bearing capacity for buildings and infrastructure projects.
This geotechnical reinforcement system contributes to global infrastructure development by offering a reliable solution for both permanent and temporary support. Its efficiency aligns with the growing demand for sustainable and safe construction practices, particularly in regions prone to geological hazards. SupAnchor's commitment to innovation ensures that this hollow bar anchor meets the highest standards, supporting projects from urban development to environmental conservation.
