A trench wall apparatus includes a base frame held at its top end by a holding means held by at least one soil excavation means, which is positioned at a bottom end of the base frame. When soil is excavated while forming the trench, the trench wall apparatus is held by a clamping means that includes at least two clamping elements on opposite sides extended laterally by at least one actuating cylinder, whereby at least one part of the trench wall apparatus is clamped in the trench, and a pressing means applies a pressing force on the at least one soil excavation means. The clamping elements and clamping cylinder are positioned on an intermediate frame displaceably mounted along the base frame. The intermediate frame is clamped and fixed to the ground by the clamping means. The base frame having the soil excavation means is pressed downward by the pressing means.
