Abstract:
The present disclosure provides helical pile leads and extensions with closely spaced perimeter shear helical plates that develop a cylindrical failure surface between the perimeter shear helical plates and soil as the helical pile is rotated into the ground, mobilizing soil-to-soil shear strength, and thus increasing the stability, stiffness and load capacity of the helical pile.
