A foundation engineering machine and method for producing a trench in the ground include a substantially vertical mast, a diaphragm wall apparatus displaceably supported in a longitudinal direction of the mast for producing the trench, and a bar-shaped holder, at the lower end of which the diaphragm wall apparatus is mounted and with which the diaphragm wall apparatus is linearly displaceable along the mast. An upper first clamping sledge with a first clamp for releasably clamping the bar-shaped holder and a lower second clamping sledge with a second clamp for releasably clamping the bar-shaped holder are movably supported on the mast. The first clamping sledge and the second clamping sledge are movable relative to each other, and the lower second clamping sledge has a connector for mounting an additional lifting device disposed on the ground, with which a force can be applied in the longitudinal direction onto the second sledge.

A pile driver driven foundation bracket system includes a foundation bracket drive unit and a foundation bracket unit. The foundation bracket drive unit includes a pile driving unit interface configured to engage with a pile driving unit, a hollow sleeve, and a foundation bracket drive interface. The pile driving unit interface is connected to a first end of the hollow sleeve, and the foundation bracket drive interface is connected to a second end of the hollow sleeve. The foundation bracket drive interface is removably connected to the foundation bracket unit. The foundation bracket unit includes a horizontal foundation bracket support arm, a foundation bracket brace having an opening, the opening being configured to allow soil to flow therethrough when the foundation bracket unit is rotated, and a foundation bracket hollow sleeve.

A device for supporting and guiding supplying lines used with a digging tool on a drilling machine is described. The device comprises a support branch, formed by a plurality of spacers, adjacent to one another in which a rope or tie-rod is inserted in a housing comprised in the spacers, a supplying pipe for the supplying line and a crosspiece comprising a seat adapted to support the supplying pipe. Each pair of adjacent spacers comprises retaining means. Each retaining means comprises a retaining element, associated to a first spacer of a pair of adjacent spacers, and a slot having a shape substantially matching the shape of the retaining element, associated to a second spacer of the pair of adjacent spacers. A retaining element, during use, engages with a slot allowing relative axial movement, in the longitudinal direction of the rope, of a predetermined amount.
