Abstract
A pile element is disclosed for supporting a structure after being driven into a soil stratum. The pile element includes a pile body defining an exterior surface of the pile. At least one plate is adapted to be retained substantially within the pile body during driving of the pile. The at least one plate is caused to protrude sideways from the pile body upon completion of driving of the pile.
Claims14
A pile assembly for supporting a structure after the pile assembly is driven into a soil stratum, the assembly comprising:
- a reinforced concrete pile element having a rectangular cross section and comprising an end and an inner wall defining a passageway for a mandrel;
- a pyramidally-shaped pile toe mounted to the end of the pile element, the toe comprising a metal housing with a rectangular upper portion and four interior walls, the walls being joined to form a tapered bottom portion, each wall defining an aperture between the upper and lower portions;
- a movable actuator substantially enclosed by the metal housing and having a bottom portion and a pyramidal cross sectional area greater than the cross sectional area of the passageway;
- and
- a trapezoidally-shaped plate corresponding to each of said apertures, each plate having a short side adjacent the actuator and a long side adjacent the corresponding aperture;
- the actuator having a first position in the housing so that each of the trapezoidally-shaped plates may be positioned interior to the metal housing and having a second position such that the bottom portion of the actuator is adjacent the interior walls of the bottom portion and bear against the short side of each of the trapezoidally-shaped plates and thereby extend each plate at least partially from the respective aperture to a point external to the metal housing.
An elongated pile assembly having an interior and exterior portions, for supporting a structure after the pile assembly is driven into a soil stratum, the assembly comprising:
- a passageway extending substantially along the elongation of and in the interior portion of the pile assembly;
- a plurality of slots extending from the passageway to the exterior portion of the pile assembly;
- a plurality of trapezoidally-shaped plates, one plate in each slot, each plate, when in a retracted condition, having a short side exposed in the passageway and a longer side displaced from the passageway toward the exterior portion of the pile assembly;
- and
- a movable actuator positioned within the passageway for applying a force to the short side of and for actuating each of the trapezoidally-shaped plates in a direction away from the passageway to an exposed position beyond the exterior portion of the pile assembly.
