PRESSURE GROUTED DISPLACEMENT SCREW PILES
A grouting module may include a lower surface configured for connection to a screw pile component, an upper surface configured for connection to an upper hollow pile shaft, a body disposed between the upper surface and the lower surface, and an axial bore through the upper surface and at least a portion of the body. The body may include a flange configured to create an annular space around the upper adapter and one or more flow injection conduits configured for injecting grout received from the upper hollow pile shaft through the axial bore extension into the annular space while the pile is advanced downward into a substrate. Once the final pile tip elevation is reached, the pile extensions above the grouting module are counter-rotated slightly to realign the ports in the grouting module from side to bottom discharge and allow post-grouting of the lead pile extension.
