Definitions

  • the invention relates to a method for creating a horizontal well in the ground and a horizontal drilling device for use in such a method.
  • Horizontal drilling devices are used to bring in trenchless construction supply and disposal lines in the ground or already laid old lines trenchless exchange.
  • Horizontalbohrvoriquesen there are a variety of different Horizontalbohrvoriquesen. Widely used are horizontal drilling devices in which a drill head is initially driven obliquely into the soil by means of a drill pipe and, starting from a drilling carriage positioned on the earth's surface, until the drill head reaches the desired drilling depth. Then the drill head is reversed to the horizontal to introduce the desired horizontal bore.
  • the target point of such a horizontal well may be, for example, in a specially excavated target mine or in a basement room or he may also, i. like the starting point, located on the earth's surface.
  • the drill head is reversed after a certain Bohrfort Kunststoff in an obliquely upward direction to let the drill head to exit again on the earth's surface.
  • CONFIRMATION COPY bore to widen. It can be provided to attach to the expansion device a newly retracted line to collect these simultaneously with the expansion of the pilot hole in the soil.
  • Horizontal drilling rigs are also used to replace trenchless trenchings buried underground. For this purpose, in a first step, the drill string is pushed by the drill carriage along the old line (and in particular by an old pipe) and after reaching a destination point, which may for example lie in a maintenance shaft of the sewer, the front end of the drill string connected to a widening device the old pipe when retracting the
  • Drill pipe is cut or burst, the parts of the destroyed old pipe are displaced radially into the surrounding soil. At the same time a new pipe can be pulled into the old pipe. By destroying the old pipe and displacing the sections of the old pipe, the new pipe can have an outer diameter which corresponds to or even exceeds the outer diameter of the old pipe.
  • Horizontal drilling devices regularly have a linear drive, with which the drill string is driven into the soil and withdrawn from it. Furthermore, a rotary drive is provided on a regular basis, with which the drill string (and the associated drilling or expanding head) can be set in rotation. Through the rotation of the drill head or the expander the propulsion in the soil can be improved.
  • the drill heads of such horizontal drilling devices have an asymmetrically shaped (e.g., bevelled) drill head front which results in lateral deflection of the drill head during movement of the drill head through the soil. If the drill head is driven in rotation simultaneously with the driving in the ground, the asymmetrical design of the drill head has no influence on the straight bore course, because the lateral deflection compensates in the middle of a turn.
  • Horizontal wellhead drilling rigs are often only suitable for use in out-of-town areas as they must be positioned at a considerable distance from the area because of the tapping path required to achieve the desired depth of drilling , in which the bore or the new line in the

  • a disadvantage of the horizontal well drilling apparatus known from DE 196 33 934 A1 is that an exact alignment of the pit to be excavated is required for this, since the direction in which the bore is started starting from the horizontal drilling, substantially perpendicular to the two narrow sides the excavation is located.
  • the horizontal drilling DE 196 33 934 A1 only two holes can be carried out in the opposite direction, starting from an excavation also in the two directions, which are perpendicular to the two narrow sides of the pit. In order to drill in the two directions, it is necessary to lift the entire horizontal drilling device out of the excavation, to rotate 180 ° about the vertical axis and then release it back into the excavation.
  • the present invention seeks to provide an improved horizontal drilling. Furthermore, an improved method for introducing a hole in the soil should be given.

  • the rod section Due to the fact that the driving ring 37 is not yet locked in the locking groove 41, the rod section can be displaced relative to the driving ring 37 during screwing in the longitudinal axial direction. As a result, the longitudinal movement of the rod section 23 required for the screwing of the rod section 23 can be realized without a complex length compensation realized by the linear drive.
  • the position of the rotary drive during the screwing is chosen so that the locking grooves 41 of the front end portion 39 a after complete screwing of the rod assembly 23 with the drill head 43 are within the driver ring 43, so that this directly by a 90 ° rotation, ie without the need for another method of linear drive, can engage in the locking grooves 41 to fix the rod assembly 23 in the longitudinal direction.
