Abstract (en)

[origin: EP0553378A1] A device for making an essentially vertical slot, filled with supporting liquid, in the soil during the construction of a sealing or supporting wall is provided with a cutting unit (100) which has at its bottom end two cutting wheels (101) which are arranged one behind the other and are mounted in such a way that they can be driven in opposite directions about parallel horizontal axes (102) and between which an intake connection (103) of a discharge line (104) for released soil material is arranged. In such a device, it is possible to control the position of the cutting unit (100) if the cutting unit (100) is held and guided in such a way as to be movable up and down on a mast supporting framework (300) via a supporting tube (200) of supporting-tube sections (201) coupled to one another in such a way as to be locked against rotation.
