DYWIDAG Strand Anchor Systems
Prestressed rock and soil anchors have become an important tool for the geotechnical or structural design engineer. Their safe and reliable use in both permanent and temporary applications is accepted throughout the world.
Anchors are most commonly referred to as tiebacks for installation angles of 15°-50° from horizontal or tiedowns (51°-90° installation angle).
Soil anchors are pressure grouted tendons installed in either cohesive or non-cohesive soil or loose rock. The anchors transfer forces into the ground through the prestressing steel and grout body. In the free stressing length the anchor remains free to move.
Typical Uses for Soil Anchors
- Anchoring of support structures for excavations such as sheet pile walls, soldier piles with lagging, drilled piles, slurry walls, and concrete retaining walls.
- Counteracting uplift forces in structures subjected to buoyancy and lateral loads.
- Stabilization of eccentrically loaded foundations.
- Stabilization of natural or excavated slopes.
