A method for the in situ casting of a foundation pile supplied with a recoverable tube-shaped form (2), said pile having an improved and measurable capacity load at its sill, and the device for carrying out the method, said device being designed for the installation within said tube-shaped form and comprising means (3) for the transmission of a compressive stress direct or indirect onto the bottom of the digging through means for the distribution of the stress, said means resting on supporting means (1) supplied at the basis of the cage, and means (12) for generating a compressive action on said transmission means, said generating means being connected to said tube-shaped form at a point corresponding to its upper edge and being associated to means for measuring the compressive stress exerted on the bottom of the digging, concrete being introduced into the form through said means which transmit said stress or otherwise being introduced into the hollow space (8) between said means and said tube-shaped form. |
