Abstract: The invention relates to an installation (10) for making a continuous wall in ground (S), the installation comprising: an excavation machine (14) having a frame (16) with a bottom end (16b); determination means (80) for periodically determining the offset between the frame and a first screen while making a second screen in the ground juxtaposed with the first screen; and correction means (50) for periodically correcting the position of the frame (16) so as to reduce the offset as determined by the determination means between the frame (16) and the first screen (E1), and maintain overlap between the longitudinal side of the frame and the longitudinal side of the first screen in such a manner that the second screen is secant with the first screen (E1) over the entire length of the shorter of the first and second screens, thereby forming the wall that is continuous.

Abstract: The invention relates to a concreting installation for concreting an excavation. The installation includes a concreting column having a top end arranged to be open in order to be at atmospheric pressure, and at least one controlled retention device situated at a distance from the open top end of the concreting column and adapted, in at least one configuration, to retain a volume of concrete inside the column. The invention also relates to a method of concreting an excavation.
