  • a pile is made as follows: In the drilling phase where the support tube 4 is rotated, the cylinders 20 are in the retracted position, and the lower end of the central injection tube 15 is closed by the cutting head 13. In addition, in this position retracted from the jacks 20, the cam 45 is urged by the sealing piston 18 so that the valves 40-42 are pressed under the blades 10-12.
  • the jacks 20 are deployed causing an upward movement of the central injection tube 15 and of the sealing piston 18 integral with the latter. During this movement, the cam 45 is tilted and the valves 40-42 are brought into their injection position where they form a closure belt around the support tube 4.
