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.

METHOD FOR PRODUCING A SEALING BASE IN THE GROUND

The invention relates to a method for producing a sealing base in the ground in which by injection of a curable grouting compound a plurality of sealing elements is produced in a first soil layer, which elements adjoin one another or overlap, wherein the plurality of sealing elements forms a solid base plate following curing of the grouting compound. It is provided according to the invention that in a second soil layer, which lies beneath the first soil layer for the solid base plate, a gel base is created by injection of a sealing gel, and that the solid base plate and the underlying gel base form the sealing base. The invention further relates to a correspondingly produced sealing base.

System for and method of stabilizing rail track structures using a load transfer apparatus

PILE COUPLING FOR HELICAL PILE/TORQUED IN PILE
20200385947 · 2020-12-10 ·

A pile includes a first pile section having a first end that engages a supporting medium and an opposing second end. A first end of a second pile section is engageable with the second end of the first pile section, each of the first and second pile sections having mating end fittings that create an in fit. A sleeve overlays the first and second engaged ends of the first and second pile sections. At least one through hole aligned with at least one corresponding through hole of the first pile section is sized for receiving a fastener far securing the sleeve to the first pile section. In another version, the ends of the pile section are engaged in contact while the overlaying sleeve has a pair of interlocking sleeve or coupler portions that are configured to provide torsional resistance. Additional pile sections can be sequentially attached to the second pile section.
