Title: METHOD AND FACILITY FOR MANUFACTURING A CONTINUOUS WALL IN THE GROUND
Abstract:
The invention relates to a facility (10) for manufacturing a continuous wall in the ground (S), comprising: an excavation machine (14) comprising a frame (16) having a lower end (16b); determination means (80) for periodically determining the separation between the frame and a first screen during the manufacturing of a second screen in the ground, adjacent to the first screen; and correction means (50) for periodically correcting the position of the frame (16) in order to reduce the separation determined by the determination means between the frame (16) and the first screen (E1), such as to maintain an overlap between the longitudinal edge of the frame and the longitudinal edge of the first screen, such that the second screen is secant to the first screen (E1) over the entire shortest length of the first and second screens.
