The driven pile (Franki-type) is constructed using a recoverable casing pipe, driven into the ground without soil extraction, cast in situ, and equipped with a disposable steel base plate (Vibro-Franki piles).
The insertion of the form pipe is carried out with overhead hammering of the pipe using diesel and/or hydraulic pile drivers with a hammer weight of no less than 3600/4600 kg.
At the lower end of the form pipe, a disposable steel baseplate of adequate thickness must be inserted.
Once the design depth is reached, the metal reinforcement is inserted and then the form pipe is filled with concrete of suitable fluidity.
The form pipe is pulled out of the ground gradually and simultaneously filled with concrete.
