SA Permanent Anchor
After drilling, the wedge cone of the anchor head is precisely fixed together with the anchoring blades into the anchor head.
Method Overview
- After drilling the anchor head, the wedge cone is tightened with the anchoring blades to ensure precise fixation to the anchoring head, while the PC strands are tensioned to prevent sagging. This enhances bearing capacity during ground movement, secures pull-out force before grouting, and simplifies the overall construction process.
Features & Benefits
- Ensures pull-out force, preventing initial tensile loss caused by slippage.
- Pre-tensioning before grout injection allows for securing a consistent pull-out force, enabling the grouting process to be completed in a single operation.
- By performing pre-tensioning before grout injection, it prevents the elongation of PC strands — a common issue in conventional anchor installations.
- Factory fabrication enables single-step completion of grouting and bearing plate installation, ensuring rapid adaptability during on-site construction.

Anchor Assembly and Installation
It must be positioned at the center of the hole, and spacers are used for connecting the nailing materials.
Care should also be taken to ensure that the surface coating layer is not damaged or peeled off.

Grouting
Ordinary Portland cement or high-early-strength cement is generally used, and the grout mixture follows the standard specifications.
