摘要： A helical pile including a heat exchanger is described. The pile is formed from a lead section and one or more extension sections. The interior of the lead and extension sections are hollow and form a heat exchanger cavity. At the lower end of the lead section is a helical blade. Rotation of the lead section causes the helical blade to screw into the ground, thus pulling the lead section downward. Extension sections are added to the lead section and the pile is rotated until it is installed to a desired depth. The pile includes an inflow tube extending a predetermined distance into the heat exchanger cavity and an outflow port connected with the heat exchanger cavity. In operation, a heat carrying fluid is pumped into the inflow tube from a heat source or sink, for example, a heat pump for a building heating and cooling system. The fluid exits the tube at a point near the bottom of the heat exchanger cavity. The fluid flows upward through the heat exchange cavity and exchanges heat with the surrounding soil. The fluid flows out through the outflow port and back to the heat source or sink.

摘要： A method for reinforcing an aggregate pier. The method includes inserting a conical-head pipe into the aggregate pier, injecting grout into the aggregate pier by injecting the grout into the inner chamber of the hollow rod, driving the conical-head pipe into a soil under the aggregate pier by driving a secondary pipe into the aggregate pier and pushing the conical-head pipe toward the soil under the aggregate pier by utilizing the secondary pipe, filling the secondary pipe with grout, and inserting a reinforcement bar into the secondary pipe and the hollow rod. This method reinforces an aggregate pier against excess tensional and compressional loads of a concrete foundation.

摘要： A pile system for support structures includes at least two piles each having a first end, a second end, and a cylindrical elongate body. Each cylindrical elongate body has an inner surface and an outer surface, extends from the first end toward the second end, and defines an internal cavity with a longitudinal axis. Each pile further includes a transition region between the elongate body and the second end, the transition region including an annular seating shoulder disposed on the inner surface of the cylindrical elongate body that defines a step increase from a primary inner diameter to a secondary inner diameter. The first end of a first pile of the at least two piles is configured to be inserted into the second end of a second pile until a first distal edge thereof contacts the seating shoulder of the second pile.

摘要： Provided are a pile joint, a pile coupling structure, and a pile coupling method that allow firm uniting of piles to be coupled. A joint (10) for coupling two piles (12) comprises: a tubular body (16) into which each pile (12) provided with a key (14) on a periphery thereof is inserted through an end (16A) of the body (16); and a fitting portion (22) formed on the body (16) so as to be fitted to the key (14) by the insertion and rotation of the pile (12). The fitting portion (22) is formed with: a tapered shape having a surface (22A) that is inclined so as to become distant from the end (16A) of the body (16) as the surface (22A) extends in the direction of rotation of the pile (12); or a wedge shape for fitting between a projection and a pile.

摘要： 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.

摘要： A foundation component having an elongated shaft with a below-ground end and an opposing above-ground end. The foundation component is installed by sleeving it over a mandrel and applying downward force to the mandrel to insert the component and mandrel into underlying soil. Proximate to the underground end, the shaft has one or more crumple zones formed along its length. When the mandrel is rotated to a locked position and upward force is applied while bracing the above-ground end of the component, one or more of the crumple zones expand transversely into the soil, depending on the soil's density, thereby increasing the component's bearing capacity and resistance to pull out.
