    摘要： An assembly for forming an elongate construction element underground, in particular a foundation pile, comprises an elongate displacement body (10) and a device for driving the displacement body into the ground in an axial direction. The displacement body is provided at an outer end (13) with at least one displacing member (14) and with an outflow opening (12) for a curing construction liquid. The at least one displacing member herein comprises at least one substantially flat blade which extends in axial direction from the outer end of the displacement body. The blade (14) is provided with at least one recess (21..24) within a periphery (15) which may or may not be imaginary.

    摘要： A load bearing pile arrangement comprising a plurality of load bearing construction pile assemblies. Each comprises a pile provided with a support manifold at an upper end thereof. Each pile includes an outer tube and an inner tube between which, when the assembly is in use, provides a pathway for fluid pumped from above and down through the inner tube to a vortex manifold where the fluid swirls before passing upwards between the inner tube and the outer tube. The fluid also swirls as it passes upwards between the tubes and by at least one collar comprising an annular ring fixedly mounted on the tube the ring having helices, which cause the fluid to continue swirling as it passes upwards between the tubes and. In use, the load bearing pile arrangement can be used to recover heat from the surrounding ground; store heat in the surrounding ground; or, to store coolth, especially in a desert locality.

    摘要： The subject invention pertains to a method and apparatus for inducing a lateral load for the purpose of increasing the force needed to lift a pile and/or increasing the downward and/or lateral load bearing capacity of a pile. The pile can be a driven or pushed displacement pile, a driven or pushed non-displacement pile, any type of bored pile, or any combination. In an embodiment, the subject invention can enhance pile performance by increasing (prestressing) permanently the lateral pressure between a pile and its surrounding soil. The subject invention can provide directional displacement through induced lateral loading of installed piles. Embodiments of the subject invention can incorporate embedded lateral loads in one or more piles.

    摘要： A geothermal driven pile (1) provided with an axial cavity closed at both ends, closed off at the one end with a connecting piece (3) provided with at least one connecting stub which is in communication with the cavity, wherein, for instance in the shape of a hose or a pipe, separating means (5,6) can be accommodated, which extend in the driven pile (1) from one end to a point close to the other end for circulating a fluid through the driven pile (1). The hollow driven pile (1) is manufactured from concrete with an extrusion method. The connecting stub terminates laterally above the driven pile and can be included in a foundation beam (7) such that the connecting stub remains accessible from outside of the foundation beam (7) for connection with a pipe system.

    摘要： The present application relates to a method of installing a pre-cast pile (9) in the ground which involves applying an enlarged head forming tool (1) to the ground until a volume of soil has been displaced or removed so as to form a void at the surface of the ground. The pre-cast pile is then driven into the ground to a predetermined depth below the void and the void is then filled with concrete or grout to form a cast-in-situ pile head. The diameter of the pile head is greater than the diameter of the pile shaft.
