Transmission Line
Transmission lines face many of the same geotechnical issues faced by other tower structures. Lateral loads from wind forces result in large overturning moment. Anchors add additional uplift capacity to new or existing transmission line tower foundations. Micropiles are appropriate for a wide range of ground conditions for structural support and can penetrate obstructions such as boulders. Dynamic compaction permits construction on loose fills and reduces seismic subsidence. Soil mix columns and aggregate piers create reinforced platforms for more uniform settlements and to resist seismic loading. Jet grouting surgically replaces in situ soils and can be performed through or around foundations for underpinning. Compaction grouting densifies loose granular soils and corrects settlement. Injection systems treat expansive clays. Driven piles are appropriate for a wide range of ground conditions and are suitable for land-based or marine-based transmission line towers. Fracture grouting reduces or reverses differential or total settlement and can be repeated to control ongoing transmission line tower settlement. Vibro replacement stone columns reinforce cohesive soils and densify granular soils for transmission line tower construction. With a foundation provided by Hayward Baker, your transmission line will remain in operation.
