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

A diaphragm wall device for creating a trench in the ground, comprising

• a base frame which extends in a longitudinal direction,
• at least one soil removal device, which is arranged on a lower end region of the base frame,
• a holding device for holding the diaphragm wall device on its upper region,
• a bracing device with at least two opposite bracing elements displaceable laterally, transversely to the longitudinal direction and with at least one actuating element, by means of which the bracing elements can be extended laterally in the trench for bracing at least a part of the diaphragm wall device,
• an intermediate frame, on which the bracing device with the at least two bracing elements and the at least one actuating element is arranged, and
• a pressing-on device, by means of which the at least one soil removal device can be applied with a pressure force,
• wherein the pressing-on device is arranged between the intermediate frame and the base frame, so that the base frame is displaceable relative to the intermediate frame by means of the pressing-on device,
• wherein the holding device is fixedly connected with the intermediate frame, and
• wherein the base frame with the soil removal device is displaceable with respect to the holding device,
• wherein
• the intermediate frame is displaceably mounted in a lower region of the base frame along the base frame and
• the holding device is fixedly connected to the intermediate frame via one or multiple longitudinal beams, which extend along the base frame.
