Definitions

  • This invention relates to piles, that is pointed stakes, posts or like longitudinal members drivable into the ground for use as supports or strengthening members.
  • An object of this invention is to increase the bearing load capacity of piles.
  • a non-core pile 1 as shown in Figure 1, includes in its walls a plurality of evenly spaced holes. To the upper edge of each hole a sharp member is pivotally attached.
  • the sharp members are moved through the holes by a hammer E or other heavy tool, which is passed through the pile and they are urged into the ground surrounding the pile, fixing the pile.
  • the hammer E has a smaller outer diameter than the internal diameter of the pile.
  • the sharp members are fin-shaped and comprise an attachment portion including a hole for receiving a bolt 7 via an elongate member having an end embedded in the edge of the corresponding aperture in the pile. Alternatively, the sharp members may be fixed on the inside wall of the pile.
  • the sharp member further includes an arcuate sharp edge for cutting into the ground with a strengthened pointed portion 6.
  • a hole A is made in the ground of slightly greater size than the pile and the pile is inserted into it, using a crib B, with the sharp members retracted.
  • the hammer E is then employed to force the sharp members outwardly and into the surrounding ground.
  • the interior of the pile is filled with liquid concrete C or similar filler material.
  • Piles according to the invention have been tested and found to be very effective. Piles were inserted into the ground and left for three days. A load was applied to each pile and increased eight times at six hourly intervals following settlement of the pile.
