Definition:
Pile screwed without vibration with double side repression and was in the shape of propeller on all the height, without vertical transport of ground
Properties:
installation of the reinforcement on all the height before concreting
tilted piles possible (up to 1/5)
the section of the pile is determined by the diameter of the propeller and the diameter of the barrel. The diameter of the propeller determines the geological capacity of bearing pressure, the diameter of the barrel determines the organic capacity of bearing pressure. The diameter of the current barrel of 310mm with 610mm is spaced 50mm. The diameter of the propeller of 460mm with 810mm.
without vertical transport of ground, even with the point (side repression).
begun again horizontal efforts by an additional reinforcing cage at the head
it can be necessary of préforer the hard layers (>20MPa).
capacity of bearing pressure until 2000kN
Scope of application:
in the environment sensitive to the sound: <85dBA with 7m of the machine
in the environment sensitive to the vibrations. The pile is installed under the combined effort of screwing and push.
without important drainage of ground
almost all profile them ground Belgians
especially in tertiary clays
