Retaining Wall Anchors
- SOIL SCREW™ Retention Wall System
- Tieback Tension-Anchor System
DescriptionFor retaining projects, Chance screw anchors can be matched to soil and heavy tension loads in the same way HELICAL PIER® Foundation Systems anchors are for compression applications.
Soil Nailing - SOIL SCREW™ Retention Wall System uses screw anchors as bearing devices as compared to grouted anchors which rely on friction. To construct a gravity wall to reinforce the soil, SOIL SCREW anchors have bearing plates spaced along their entire lengths. Anchor size and grid spacing are designed to local soil conditions and load requirements. A shotcrete-reinforced veneer often is applied to the wall face.
Tieback - Chance screw anchors for tiebacks in soldier-pile/waler walls come with shaft sizes and single- or multi-helix plate diameters selected for job-specific requirements. Applications include building sitework, roadways, retaining walls, levees, dams and revetments.
