Abstract:
A reinforced helical pile system suitable for use in seismically active areas incorporates steel fibers in the grout and a fiber reinforced polymer sleeve (casing). A low-friction driving assembly and low-friction sleeve couplings enable the sleeve to be drawn into the soil substantially without rotation, reducing power consumption and preserving the integrity of the casing.
