Abstract

A boring apparatus is described which comprises a substantially hollow vessel (2) with a fixed base (5) and a rotatable base (6). The rotatable base is provided, at its circumference, with at least one side cutter (8) which may be rotated with the rotatable base from a first position, in which the at least one side cutter serves to cover a respective opening (13,14) provided in the vessel wall, to a second position, in which the opening in the vessel wall is exposed. <IMAGE> <IMAGE> <IMAGE>
