A process and device are disclosed for laying deep foundations, such as pile foundations, subterraneous curtains or foundations with prefabricated parts. The device has a motor-driven cutter with at least one cutting head and means for evacuating the excavated earth from the cavity and for supporting the walls of the cavity. The object of the invention is to develop a process and device for laying deep foundations in as short a time as possible using a simple technology. For that purpose, the device has a separating element (2, 27) and other elements designed or arranged on the device and/or separating element (2, 27) that allow the device to be used both for excavating the cavity and for subsequently filling the concrete body remaining in the ground. The device allows the excavated sludge to be used as cavity supporting medium. |
