Apparatus and methods for the placement of pipe piling

A pipe pile assembly comprising:

• At least one pipe pile, each pipe pile having an interior having an inner diameter, a bottom end and a top end, the at least one pipe pile comprising a first pipe pile;
• A tip insert movably disposed proximate the bottom end of the first pipe pile and having a flush mode and a pushed-out mode, the tip insert comprising:
• a prism with an upper end and a lower end and having a transverse cross-section with at least three sides;
• A lower plate fixed to the lower end of the prism, the lower plate is configured to fit snugly into the inner diameter of the bottom end of the first pipe pile;
• and
• A point that protrudes below the lower plate;
• At least one rod section, the at least one rod section comprising a first rod section disposed within the interior of the first pipe pile, wherein the first rod section is joined to the tip insert;
• and
• A first receiving plate attached transversely within the interior of the first pipe pile proximate to the bottom end of the first pipe pile, the first receiving plate having a tip insert receiving opening configured to receive a portion of the prism and permitting axial translation of the prism and inhibiting the rotation of the prism within the tip insert receiving opening;
• Wherein the tip insert is in the flush mode when the lower plate is disposed against the first receiving plate forming a flush end with the bottom end of the first pipe pile;
• and
• Wherein the tip insert is moved to the pushed-out mode such that the prism is spaced from the tip insert receiving opening by at least one of mechanical means and introducing material under pressure into the interior of the first pipe pile.
