Helical piers and anchors are used in a variety of tension and compression applications in the transportation sector. Constructability and the mitigation or elimination of site issues drive the increasing popularity of helicals in this arena. Using small, low-impact equipment, helicals screw in gently with no vibration to existing infrastructure. Quick installation requires fewer and shorter shutdowns. Helicals are segmented piles, easily staged and stored, mitigating overhead and other access issues. Limited or no excavation is required, mitigating or eliminating spoils and environmental concerns. All of these advantages translate into a cost-effective alternative to other anchoring and foundation systems.
Popular uses of helical piles in the transportation sector include:
- Tiebacks and Soil Nails for abutments and overpasses
- Anchors for transformers, switchgears, street lights, and guys
- High-capacity foundation piles up to 150 tons
- Low-capacity foundation piles for signs, signals, and switching equipment
