Definitions

  • the invention relates to a method for measuring a borehole in the ground that is an entry point on the ground surface and has a base at its lower end, with one Drill pipe is generated that one above the entry point Clamping point and a drill bit at its front end carries, by means of a with the drill pipe to the base in the incline inserted into the borehole.
  • the inclinometers used usually have two effective inclination angle measuring units in mutually perpendicular planes on. From the measured values of the two units mentioned then the size of the angle of inclination relative to the vertical and the direction of the angle of inclination with respect to the reference direction determine.
  • the present invention has for its object the above Procedure for measuring a borehole again to simplify.
  • a horizontal offset between the clamping point and the entry point can be set to zero in the first approximation, so that the calculated offset w also refers to the entry point can be.
  • the inclination direction and the inclination angle at the clamping point can be measured simultaneously with the above-mentioned measurement using the inclinometer installed in the drill pipe or after the pulling of the drill pipe, the inclination angle and inclination direction in the clamping plane can be subsequently determined using the inclinometer installed in the drill pipe .
  • the further inclinometer can be arranged on a drill guide for the drill pipe on the leader near the entry opening or preferably in the drill pipe at its upper end, which always remains above the drill guide. Deviations of the drill pipe from the vertical at the clamping point due to inclined positions of the leader can hereby be taken into account.
  • the inclination angle is usually measured in one identifiable with respect to a predetermined reference direction Rotary position of the drill pipe with the inclusion of two to each other vertical inclination angle components, from which the absolute angle of inclination in relation to the vertical and the direction of inclination in relation to the predetermined Reference direction is calculated.
  • the procedure is usually carried out in such a way that that before the drilling of the borehole a rotary position of the drill pipe with respect to a reference direction, e.g. B. on the drill pipe a rotary position near the rotary drive head Leader is marked and then the drill pipe is driven in rotation to sink the borehole. After reaching the The drill pipe is in the same rotary position brought against the reference direction and the angle of inclination towards the vertical and the direction of inclination towards the Reference direction determined. From the measured inclination angle a and the read length 1, the horizontal offset of the Foot point compared to the clamping point according to size and direction calculated according to the invention.
  • the process of measuring the angle of inclination when pulling or sinking several times at any step height can the process of measuring the angle of inclination when pulling or sinking several times at any step height become. With each step, the angle of inclination at the end of the Drill pipe and the corresponding cantilevered pipe length determined and from this the position of the drill head after the named computational method determined. From this, the path of the drill head can be in the borehole and thus the course of the borehole is calculated and be recorded.
  • the spatial course of the borehole can determined by the angle of inclination and direction of inclination over the depth and displayed graphically or in tabular form.
  • the procedure can be performed that the measured values of the inclination angle using the inclinometer measured and stored over time and that by means of a separate measuring device located outside the borehole the clamping position of the drill pipe measured over time and is saved and that the spatial course of the borehole is determined by the measured values of the angle of inclination and the Clamping position can be correlated over time.
  • a device such as that described in the earlier application mentioned is suitable for carrying out the method.
  • a further development according to the invention comprises a drivable drill pipe which is tubular, a drill guide for the drill pipe near the entry point, a drill bit at the front end of the drill pipe, a first inclinometer for measuring an angle of inclination a, which is arranged behind the drill bit in the drill pipe, and one second inclinometer for measuring an angle of inclination ⁇ k , which is arranged above the drill guide for the drill pipe, means for measuring the length 1 of the drill pipe projecting from the drill guide and means for marking a predetermined rotational position of the drill pipe with respect to a reference direction at any depth.
  • At least the first inclinometer comprises an independent current source, a timer and a data memory for storing measured inclination angles and times.
  • the second inclinometer can be arranged in any protected position on the leader, but in particular at the upper end in the drill pipe. Alternatively, a spirit level can be provided on the leader.
  • a drilling device with the deformed drill pipe brought down is shown in a side view.
  • the deformation of the drill pipe is assumed lying in the drawing plane.
  • a self-propelled caterpillar vehicle 12, which carries a vertically oriented leader 13, stands on a floor surface 11.
  • a drill rod 16 is connected to the rotatable drive head 14 and guided in the rod guide 15. It enters the ground at an entry point 17 and lies with a curvature in the borehole, not shown.
  • At the lower end there is a first inclinometer 21 in the drill pipe 16 immediately behind a drill bit 19.
  • the diameter of the drill hole is larger than that of the drill pipe 16 and that only the drill bit 19 is in contact with the drill hole.
  • the position of the first inclinometer 21 is assumed to be the base 18 of the borehole.
  • the center of the rod guide 15 is assumed to be the clamping point 20.
  • the drill pipe follows a bending line which is characterized by the length 1 of the base point below the clamping point and by the horizontal offset w of the base point relative to the clamping point.
  • the inclinometer 21 detects the angle of inclination a of the drill pipe relative to the vertical. As shown, the horizontal offset w is calculated with 2/3 ⁇ 1 ⁇ tg ⁇ .
  • Below the rotary drive head 14 there is a second inclinometer 22 in the drill string.
  • the drill string 16 between the rotary drive head 14 and the rod guide 15 is not curved and thus the axis of the inclinometer 22 in any height position of the rotary drive head 14 on the leader with the alignment of the rod guide 15 matches.
