Abstract

The invention relates to a method for the production of a back-cut cavity, in particular, for the production of a support member. An essentially straight hole (7) is produced in a subsoil (5), whereby a device (9), with a rotatable shaft (11) and at least one radially displaceable excavating element (17) arranged thereon, is introduced into the hole (7). Said device (9) is set in rotation, whereby the at least one excavating element (17) excavates or loosens the material of the subsoil (5) in the region surrounding the working region (15) of the flexible elements (17) on the device (9) due to the centrifugal forces. During the excavation and loosening of the subsoil (5), or thereafter, the excavated or loosened material is flushed away to form a back-cut cavity by means of a flushing agent (21).
