Abstract
The invention relates to a displaceable device unit for producing a through-hole in floors and back-fills, comprising an expansion unit (2) consisting of at least one first and one second expansion body (2a, 2b) with pressure surfaces (4), an expansion body joint (3) that is arranged between the expansion bodies, and means for obtaining a relative movement of the expansion body by a means supply line (1). Both pressure surfaces can be brought into contact with an inner wall (5) of the through-hole (6) by activating, in an alternating manner, the respective expansion body and a proper movement can be produced in the direction of a through-hole path by pulling and pushing the expansion body that is not arranged in a pressure or force fit. A head module (7) is arranged in the front region of the device unit, said module being connected to an expansion unit by a head-joint connection (8a). Means enabling a relative movement to be carried out between the head module and the expansion unit for producing pressure and compression forces on the front of the device head are provided.
