1. A trench wall cutting device, comprising
a trench cutter comprising cutting wheels, which is constructed from at least two separate cutter modules configured to be assembled to each other to form the trench cutter, and
a supporting structure on which the trench cutter is arranged, the supporting structure being for suspending and moving the trench cutter in a vertical direction to form a cut trench in the ground,
wherein
the supporting structure has a guide apparatus configured to supply the separated cutter modules for assembly to each other to form the trench cutter at a working region at which the cut trench is to be created, and
the supporting structure comprises at least one guide rail, along which the individual cutter modules are mounted so as to be shiftable transversely to the cut trench, the at least one guide rail being arranged orthogonally to an axis of rotation of the cutting wheels.
