Load bearing construction pile

摘要

602528 Disclosed is a load bearing construction pile assembly (4) for structural support and the recovery and or storage of heat in the upper level of the ground. The pile assembly (4) comprises a pile (6) and a support manifold (8). The support manifold (8) is located at an upper end (10) of the pile (6). The pile (6) comprises an outer tube, inner tube and vortex manifold located at a lower end portion of the pile (6). When the vortex manifold is in use, fluid is passed downwardly through the inner tube and upwardly through an annular passageway. The annular passageway is defined between the inner and outer tubes. The vortex manifold induces swirling of the fluid so that it enters the annular passageway as a spiral flow.
