<p>A method for providing deep partition walls in the ground, wherein, by means of a drill head (3), pits (8) are drilled, spaced apart, to the desired depth, whereafter the ground panel (11), located between the two pits (8), is excavated by means of a deep-wall cutter (10) comprising at the two sides thereof guide elements (12), guided by the walls of the pits (8) during excavation of the ground panel (11). In this manner, successive ground panels can interconnect perfectly to yield a sealing wall, continuous at all points, consisting of a hardenable mass to be provided in the excavated trench. <IMAGE></p> |
