    • A pile boring machine comprising:
      - a mast (2)
      - a kelly for the realization of bored piles, constituted by a battery of rods (7,19) displaceably inserted one into the other wherein the most inner rod (9) supports an excavation tool (5);
      - a rotary table (1) which bears the kelly and vertically slides along the drilling mast (2), the said rotary table being provided with means (8a) for rotating the battery of rods (7,19) around its longitudinal axis;
      - means (10) adapted for displacing and recompacting the rods of the battery and;
      - motorized means (6) adapted for exerting a traction and a thrust on the rods during the excavation. Characterized in that, at least part of the rods (19) of the battery of the kelly is entirely positioned under the rotary table (1) by which it is put in rotation.
