  • the lateral offset is such that the guide sleeve is laterally spaced from the undercarriage.
  • a particularly preferred embodiment of the invention is that a center axis of the guide sleeve is located on a turning circle of the drilling axis of the drilling tool during a rotation of the upper carriage relative to the undercarriage.
  • the drilling tool can be brought by a simple rotation or pivoting of the upper carriage relative to the undercarriage in a coaxial position to the guide sleeve.
  • On the mast can be carried out over a corresponding adjustment kinematics and a certain axial displacement of the mast with respect to the superstructure. This results in a wider turning circle area, in which the guide sleeve can be arranged on the undercarriage.
  • the drilling guide is arranged close to the ground, but spaced therefrom.
  • An arrangement close to the ground allows a particularly good adjustment.
  • the drill guide is spaced apart to the ground, so that it can be moved easily with the drill. This allows efficient creation of multiple holes.
  • the drilling guide can be attached to any suitable location on the undercarriage.
  • the support means may be constructed of steel beams and preferably have the greatest possible rigidity.
  • the carrier device can be mounted on the chassis, on the lower part of the slewing ring or directly on a special fastening device of a transporting vessel in the case of a crawler chassis.
  • the attachment is preferably realized by means of bolts and / or screws, so that a simple release of the support device is made possible.
  • the drilling guide itself may be releasably secured to the support means.
  • the guide sleeve has an outer sleeve holder, in which releasably at least one adapter element is held, which is adaptable to a provided bore diameter.
  • the adapter element may be a corresponding sleeve or shell elements of a sleeve, which are releasably attachable in an annular sleeve holder.
  • the inner diameter of the guide sleeve is matched to the outer diameter of the drilling tool, that at least in the introductory bore a sufficient clearance is formed.
  • the guide sleeve can be formed in one piece. According to a development of the invention, it is particularly expedient that the guide sleeve is designed to be hinged with at least two guide segments.
  • the guide sleeve can be formed from two or more shell-shaped guide segments. Thus, the guide sleeve can be opened for maintenance or repair purposes and possibly easily maintained.
  • a particularly good flexibility in operation is achieved according to an embodiment of the invention in that the guide sleeve on the support means adjustable, in particular pivotally articulated.
  • an adjustment of the guide sleeve can not be done solely by a method of the drill but also by appropriate adjusting devices. It can be a linear adjustment in the horizontal plane or a pivoting about a substantially vertically directed pivot axis allows.
  • a further improvement of the adjustability is achieved according to an embodiment of the invention in that the carrier device has at least one support arm, which is designed to be telescopic.
  • the carrier device has at least one support arm, which is designed to be telescopic.
  • the inventive method for creating a hole in the ground is characterized in that the drilling tool is guided by a drill guide, which is attached to the undercarriage offset to a longitudinal axis of the undercarriage of the drill, wherein the drill guide has a guide sleeve through which the drilling tool slides through leading ,
  • the method can be carried out in particular with the drilling device described above. It can be achieved the advantages described thus.
  • a preferred embodiment of the invention is that in the bore a foundation element is created.
  • the foundation element can be made in particular by introducing a hardenable mass and / or a rod element.
  • a so-called bored pile is created in the bore, wherein the borehole is filled with the hardenable mass, in particular concrete, when pulling the boring tool.
  • a reinforcement cage and / or one or more reinforcement beams can be used.
  • a plurality of holes are created, which are arranged along an arrangement line, and that the undercarriage of the drilling device is aligned and moved parallel to the arrangement line.
  • the drill can be moved in a predetermined sequence of steps parallel to the arrangement line.
  • a plurality of boreholes are created intersecting, with a bored pile wall being formed.
  • first a first number of primary bores are created and filled, which are spaced from each other.
  • so-called primary bored piles are produced.
  • the respective distance of the adjacent primary bored piles is smaller than the diameter of the bored pile, in particular of the secondary boring piles to be created.
  • the secondary bored piles are created so that secondary bores defined between the previously introduced primary holes with the primary bored piles created therein overlapping introduced. In this way, the primary bored piles and the secondary bored piles also overlap so that a laterally closed bored pile wall is created.
  • Such a bored pile wall can be used as a support wall or as a sealing wall, for example in a Baugrubenumsch proof.
  • the carrier device 12 has an undercarriage 14 with two lateral crawler tractors 16.
  • an upper carriage 18 is rotatably mounted.
  • a vertical mast 20 is arranged and articulated via neck cylinder 22 tiltable.
  • an unillustrated rotary drive is adjustably mounted.
  • a schematically indicated drilling tool 26 is driven in rotation and retracted vertically down to create the hole in the ground.
  • the upper carriage 18 is rotatable relative to the undercarriage 14, so that he relative to a longitudinal axis 15 to the undercarriage 14 can assume a twisted position.
  • the superstructure 18 preferably has a rotation of 90 ° relative to the undercarriage 14 with the longitudinal axis 15.
  • the undercarriage 14 can be positioned and moved with its longitudinal axis 15 parallel to the arrangement line 3.
  • a drilling guide 30 is attached to a crawler trawler 16 of the undercarriage 14.
  • the drilling guide 30 is provided with adjusting cylinders 50, whose function will be described in more detail below.
  • the drill guide 30 has a guide sleeve 32, which is constructed from two cylindrical half-shell-shaped guide segments 38.
  • the guide sleeve 32 is releasably mounted in an annular sleeve holder 34.
  • An inner diameter of the guide sleeve 32 is formed to match the outer diameter of the respective inserted drilling tool 26, so that an exact guidance of the drilling tool 26 is ensured in the rotating drive and axial method.
  • the guide segments 38 can be solved in the sleeve holder 34 and replaced by matching guide segments 38.
  • the annular sleeve holder 34 is itself composed of two semi-circular ring segments 37. These ring segments 37 are pivotally connected to each other via a pivot joint 35 and mounted on a support arm 42 of a support means 40. On the other hand, the free ends of the ring segments 37 are each provided with a ring eyelet 39, through which a locking bolt 36 can be plugged into a tight closure of the sleeve holder 34.
  • the closed position of the sleeve holder 34 is in FIG. 3 shown.
  • the sleeve holder 34 is pivotally mounted via the pivot joint 35 at a free end of the support arm 42.
  • the support arm 42 is horizontally displaceable or telescopically mounted in a receptacle 46, which in turn on a bar-shaped Base support 44 of the support means 40 is attached.
  • the sleeve-shaped receptacle 46 for the support arm 42 is stiffened by means of support beams 45 on the base support 44.
