Abstract: A hollow pile suitable for being sunk substantially vertically into the soil by screw-sinking, said hollow pile being characterized in that it has: at least one helical fin (2) having a flattened shape and a small pitch suitable for causing the pile to be sunk by a few centimeters per turn, when said pile is caused to move in rotation, the helical fin (2) finding itself united mechanically with and in thermal contact with the outside wall of the pile (1); and internal partitioning (3) defining an axial compartment (11) and an outer compartment (12) that communicate with each other at the bottom (13) of the pile; said hollow pile being characterized in that: the helical fin (2) is in direct thermal contact with the outer compartment (12) through the thickness of wall of the pile (1); and the outer compartment (12) has a flow section (S2) that is significantly smaller than the flow section (S1) of the axial compartment (11).
