Trench wall cutting device and method for cutting a cutting trench in the ground

Abstract

The invention relates to a trench wall cutting device comprising a trench cutter having at least one cutting frame unit and at least two cutting wheels arranged in the longitudinal direction of the cutting frame unit and is configured for cutting a substantially vertical cutting trench in the ground, a supporting structure for suspending the trench cutter in a cutting position and moving it in a substantially vertical cutting direction for creating the cutting trench, and a feed device for feeding the trench cutter in a feeding direction which is oriented transversely to the cutting direction. According to the invention, it is provided that the feed device is configured for feeding the at least one cutting frame unit with the two cutting wheels in a transversely-oriented feed position, wherein the longitudinal direction of the cutting frame unit is oriented in parallel to the feeding direction, and that a pivoting device is provided by means of which the cutting frame unit with the cutting wheels can be pivoted from the transversely-oriented feed position into the substantially vertical cutting position.
