Vertical Installation of Corrugated Steel Pipe
Contech Engineered Solutions (Contech) installs corrugated steel pipe (CSP) to form wind turbine foundations. After excavating, Contech installs the pipe vertically within the hole and quickly backfills around it with a concrete/slurry mix to prevent the excavation from caving in. At that stage – after the pipe is backfilled and before the interior is filled with concrete – the pipe must resist the lateral pressure from the slurry. SGH helped Contech by evaluating the pipe’s potential for buckling.
