A wing type anchor body opens up when a pack is pressure grouted, compresses (apply bearing pressure) a borehole surface, and increases tension. SAMJ-PEA anchor is a complex type anchor that utilizes bearing pressure and compressive friction at the same time.
Features
- Less affected by progressive debonding as the stress generated on ground is distributed by expanded wings
- Anchor force increases with increased compression surface and bearing pressure
- Grout cures after wing expansion causing no damage to anchorage bulb unlike similar products that stresses an anchor after grout is cured
- A permanent anchor that utilizes compressive force and bearing pressure at the same time
