- Diaphragm wall milling devices are used to create individual slits, diaphragm or cut-off walls that can reach depths of up to 100 meters and more. Such diaphragm or cut-off walls are used, for example, to support construction pits or to create a water barrier. It is also possible to use such milling machines to extract bo den treasures. In certain cases it is necessary to construct a diaphragm wall in or near a structure, in a tunnel or in a confined space. Conventional carrier devices with large masts and large trench cutters cannot be used for this.
- EP 05 18 297 B1 discloses a compact trench wall milling device for creating slots.

According to a development of the invention, it is preferred that a first milling frame unit with the milling wheels and at least one further milling frame unit with a drive unit, a pump unit, a supply unit, guide plates and/or a holding device are provided.

- the dimensions of the receiving recess can be designed in such a way that, when swiveling in, there is no or no significant increase in the milling frame units compared to the transversely directed lying position.
- a bevel or an arcuate area can be provided on the side areas of the receiving recess, which makes pivoting into the ground easier.
- a frame for stiffening the edge can preferably be formed along the receiving recess. The frame can simultaneously serve as a guide frame during milling.
- On At least part of the pivoting device can be designed in the frame for pivoting the at least one milling frame unit.
- the trench wall cutter can be formed from a single cutter frame unit. According to a further development of the invention, it is particularly preferred that the trench cutter is assembled from a plurality of cutter frame units at the work area. Even with very limited slab heights, trench wall cutters with relatively long guide frames can be formed, which allow particularly good guidance and thus enable a milled trench to be created in a particularly precise position.
