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 method for gradually introducing thin-walled pipes into the ground includes inserting a pipe clamp, which has been arranged horizontally on a mast, into a horizontal pipe, bracing the pipe clamp (pipe gripping jaw) with the rear part of the pipe, moving the pipe clamp back with the pipe braced thereon, erecting the mast, with the tools, the pipe clamp and the pipe, into a vertical position, introducing the pipe to the desired depth with the tools, unclamping the pipe clamp and pulling it out of the pipe, and repositioning the mast back into a horizontal position. A device has a carrier unit, a mast, which can be pivoted between vertical and horizontal, tools with a pipe clamp, arranged on the mast, and a magazine a pipe arranged substantially horizontally. The pipe clamp is inserted into the pipe coaxially in relation to the pipe and substantially horizontally.

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.

The invention relates to a drilling device for producing a drilling column in the soil comprising a mast, a drill drive arranged on a carriage, which is movably supported along the mast, a drilling tube which can be driven in a rotating manner by the drill drive and is movable along the mast in order to produce a drill hole, and a tube hopper that is connected to the drilling tube and comprises a storage space for filling material to fill the drill hole during the extraction of the drilling tube. In accordance with the invention provision is made for the tube hopper to be arranged in the drilling direction above the drill drive and to be connected to the drilling tube. The invention further relates to a method for producing a drilling column in the soil.

A soil structure tool for building structures in soil, placing structures in soil, or both, may improve the load bearing capability for soil by using multiple devices as part of a single tool. The soil structure tool may be operated to place a first device in a working position while placing the remaining device or devices in a non-working position so the first device in the working position may be used without interference from the remaining tools. Moving devices attached to the soil structure tool between the working and non-working positions permits building structures in soil or placing structures in soil without requiring multiple vehicles or other platforms to hold various devices and without requiring multiple devices to be attached to or detached from a vehicle or other platform.

The invention relates to a construction machine, in particular a drilling and/or pile driving device, for foundation construction comprising a chassis and a leader arranged on the chassis for the longitudinally displaceable guidance of a drive head. Provision is made for the leader to be pivotable on the chassis by means of a pivot drive about a pivot axis that extends at least approximately parallel to the longitudinal axis of the leader. In accordance with the invention at least one locking element is provided which can be displaced between a first position, in which it fixes the leader around the pivot axis in a rotationally fixed manner on the chassis, and a second position, in which the leader is released. In addition, according to the invention a setting device is provided for the remote-controlled displacement of the locking element.
