This measuring apparatus has at least one measurement probe (10) that can be lowered into the hole and that has at least one measurement signal transmitter (12) for transmitting a measurement signal and at least one measurement signal receiver (14) for receiving the measurement signal reflected at a wall region (5) of the hole. The measuring apparatus further has an evaluation unit for determining a wall distance between the measurement signal transmitter and the wall region of the hole, the received reflected measurement signal being able to have a measurement distance associated with it on the basis of an association rule. There is further provision for a calibration device that is connected to the measurement probe and that has at least one calibration element (22). The measurement signal transmitter is designed to transmit a calibration signal that is reflectable at the calibration element, the measurement signal receiver being designed to receive the calibration signal reflected at the calibration element. The evaluation unit is designed to change and calibrate the association rule on the basis of the calibration signal reflected and received from the calibration element.

Goods & Services
Building elements not of metal, in particular foundation
elements, foundation piles and bored piles. Civil engineering construction, namely, preparation of
foundation works, foundation piles and bored piles.
The invention relates to an earth working apparatus having an undercarriage which is designed as a running gear, and an upper carriage which is supported in a rotatable manner on the undercarriage and has a driver's cab as well as a drive motor for the undercarriage. According to the invention, between the undercarriage and the upper carriage an extension segment is arranged, through which a vertical distance between the undercarriage and the upper carriage is extended. On the extension segment between the undercarriage and the upper carriage a support means for tilt protection is mounted. The invention furthermore relates to a method for earth working with an earth working apparatus of such type.
A ground working tool comprising a tubular base body with an inner receiving space for receiving a cylindrical core of solid ground material, connector mechanism for connecting the tubular base body with a rotary drive and locking mechanism for locking the core in the receiving space of the tubular base body. The locking mechanism involves at least one locking unit having a guide rail being disposed at an inner side of the tubular base body and arranged with a deviation angle relative to a tangential direction of the tubular base body and the locking unit further comprises at least one locking element, which is moveably mounted on the guide rail between a radially outer releasing position and a radially inner locking position, in which the core is clamped within the receiving space by means of the at least one locking element.
The invention relates to a method and to a device for constructing a foundation, wherein a foundation pipe (1) is impact-driven into a ground. According to the invention, prior to impact driving by means of a drilling tool (22), the drill diameter of which is substantially smaller than a diameter of the foundation pipe (1), at least one bore (5) is made in the ground in the circumferential region of the foundation pipe (1) to be inserted. The ground material removed during drilling substantially remains in the bore (5). The invention further relates to a foundation having a foundation pipe (1) produced accordingly.
The invention relates to a cleaning device for cleaning a bottom of a borehole in the ground and also to a method for creating a bored pile in a borehole. The cleaning device has a pumping means, through which sedimented ground material in the region of the bottom of the borehole can be sucked away via a suction opening and can be discharged from the borehole via a suction line. At least one flushing nozzle is provided, through which a flushing jet can be produced, which exits the cleaning device and flushes sedimented ground material from the bottom of the borehole. A bored pile can then be produced in a thus cleaned borehole.
The invention relates to a method and to a device for creating a foundation element in the ground, wherein ground material is removed by means of a drilling tool and a borehole is created, into which a pile pipe and a curable medium are introduced. The borehole is created having a boring diameter that is greater than an outside diameter of the pile pipe by a specified amount, wherein an annular space is formed between a borehole wall and an outer face of the pile pipe. The removed ground material is conveyed in an interior of the pile pipe, while the annular space is kept substantially free of removed ground material. The curable medium is introduced into the annular space in order to anchor the pile pipe in the ground.
The invention relates to a drilling tool for earth drilling with a drill rod element which can be connected to a rotary drive and can be driven in a rotating manner about a drilling axis, a frame-like housing and at least one removal tooth which is supported in a radially adjustable manner in the housing between a retracted position in the housing and an operating position, in which the at least one removal tooth projects radially from the housing.
Furthermore, on the drill rod element in the housing a transmission mechanism is arranged, through which a stroke and/or rotational movement of the drill rod element can be translated into a radial movement for radial adjustment of the at least one removal tooth.

E21B 7/00 - Special methods or apparatus for drilling
The invention relates to an earthworking tool, comprising an undercarriage, which is disposed as a chassis, and a superstructure, which is rotatably mounted on the undercarriage and which has a driver compartment and a drive motor for the undercarriage. A extension segment is arranged between the undercarriage and the superstructure, by means of which a vertical distance between the undercarriage and the superstructure can be extended. A support device to prevent tipping is provided on the extension segment between the undercarriage and the superstructure. The invention further relates to a method for earthworking by means of such an earthworking device.
