Helical screw pile assemblies

A pile assembly comprising:

• an elongated member comprising a plurality of holes, the plurality of holes displaced helically along the surface of the elongated member;
• and
• a disc member comprising:
• an outer peripheral extent and an inner peripheral extent;
• a slot extending between the outer peripheral extent and the inner peripheral extent to form spaced-apart first and second ends;
• and
• a plurality of protruding elements displaced radially along the inner peripheral extent;
• whereas in a first unassembled configuration, the first end and second end of the disc member are substantially coplanar with each other;
• and
• whereas in a second assembled configuration, the first end and the second end of the disc member are axially separated from each other such that the disc member forms a helical shape and the plurality of protruding elements engage with the plurality of holes along the surface of the elongated member.
