Abstract
In a method for building immersed foundations on a prepared bed without preliminary unwatering by means of a platform which is intended to support the final structure, the steps which consist in positioning in the underwater bed a support having at least three bearing points which are so adjusted as to project from the bed to a height corresponding to the intended depth of the seating plane, in lowering the platform onto the bearing points, in placing a hardenable material such as concrete or mortar on the foundation bed so as to imprison at least the lower ends of anchoring means which extend downwards from the platform.

A method for building immersed foundations on a prepared bed without preliminary unwatering by means of a platform which has on its underface downwardly extending anchoring means and which serves as a cover for the concrete employed in the construction of the foundation and which defines a seating surface for the final structure, comprising
- positioning in the underwater bed a support constituted by at least three bearing points which project from said bed;
- adjusting the height of the bearing points as a function of the depth selected for the seating plane;
- lowering said platform underwater so as to rest on the bearing points;
- enclosing the space between the foundation bed and the platform;
- pouring a plastic material which is capable of setting and hardening into the said enclosed space in sufficient quantity to ensure that said platform anchoring means are imprisoned therein, without reaching the underface of the platform;
- and then, after a sufficient time for the plastic material to set and harden, so that it constitutes with the platform a rigid and leaktight hollow body, filling the said hollow body with material in the plastic state, capable of setting and hardening.
Combined means for the construction of immersed foundations, comprising
- a support having at least three bearing points of adjustable height relative to a foundation bed;
- a platform which rests on said bearing support and has on its undersurface anchoring means projecting downwardly of a lesser quantity than said bearing points;
- means to enclose the space between the foundation bed and the periphery of the platform;
- and
- means for pouring hardenable material such as concrete between the platform and the bed in order to embed the anchoring means in the hardenable material.
