Definitions

  • the invention relates to a method for creating and measuring a borehole in the ground according to the preamble of claim 1 and to an arrangement for creating and measuring a borehole in the ground according to the preamble of claim 9.
  • the invention has for its object to provide a method and an arrangement for creating and measuring a borehole in the ground, which allow reliable creation and measurement of the borehole.
  • the method according to the invention is characterized in that the borehole is created by drilling, that between a carrier unit above a ground surface and a measuring body is tensioned a measuring cable, that the measuring body is inserted and lowered into the borehole in the ground, that the positions of at least two vertically spaced cable points of the tensioned measuring cable are determined by means of angular and distance measurements and that on the basis of the determined positions of Rope points the position of the measuring body in the borehole is determined as a measure of the position of the borehole.
  • the arrangement for creating and measuring the borehole in the ground is inventively characterized in that a rotatably drivable drilling tool for creating the borehole is provided that a measuring body is provided, which is suitable for use in the wellbore and lowered, the measuring body in contact with a Boreholewandung is that a measuring cable is provided, which is tensioned between a pivot point on a support unit above a ground surface and the measuring body in the borehole, that a measuring device is provided, by means of which by means of angular and distance measurements, the positions of at least two vertically spaced points of the cable tensioned Measuring cable can be determined, and that an evaluation device is provided, with which the position of the measuring body in the borehole as a measure of the position of the borehole on the basis of the determined positions of the cable points can be determined.
  • a first basic idea of the invention can be seen in tensioning a measuring cable between the carrier unit above the ground surface and the measuring body in the borehole.
  • the orientation of the measuring cable in the room is determined. Based on the determined orientation of the measuring cable, the position of the measuring body in the borehole and thus the position of a corresponding section of the borehole is determined.
  • the spatial positions of at least two cable points of the measuring cable are determined. These rope points are basically freely selectable, but are preferably above the soil surface. Between the spaced-apart cable points, a mathematical vector is spanned whose orientation is used to determine the position of the measuring body.
  • the position of the measuring body or the point of articulation of the measuring cable on the measuring body can be determined via the direction of expansion of the measuring cable and the position of a cable point with respect to a given reference point.
  • At least two measuring cables are stretched between the measuring body and the carrier unit.
  • the arrangement of several measuring cables makes it possible to determine not only the pure position of the measuring body but also its spatial orientation.
  • a lateral tilting of the measuring body, in particular a deviation from the vertical can be determined by a plurality of measuring cables.
  • At least two positions of the measuring body are determined at different depths in the borehole. It is particularly preferred that a first position of the measuring body in the region of a drill neck, ie at the upper end of the borehole, and a second position of the measuring body are determined at a predetermined depth below the drill neck. This makes it possible to reliably detect a deviation or an offset of the borehole from the drilling attachment.
  • a depth position of the measuring body is determined. Based on the known depth position as well as the known vector between the rope points, the position of the measuring body in the borehole can be precisely calculated.
  • the depth of the measuring body can be determined for example via a measuring device on the measuring body or by determining the cable length, starting from a reference point.
  • the cable length of the measuring cable between a known reference point, for example on the carrier unit, and the articulation point on the measuring body can be determined, for example, by a Abspulpen of a winch.
  • a drilling tool which is used to create the borehole, from the borehole is pulled and that the drilling tool swung after pulling out of the wellbore from a borehole axis and the separate measuring body is pivoted into the borehole axis.
  • the measuring body can then be inserted along the borehole axis in the borehole and lower it.
  • both the drilling tool and the measuring body are held by a pivotable mast of the carrier unit and can pivot out of the borehole axis by pivoting the mast or pivot into the borehole axis. The insertion of the measuring body in the created hole can thus be particularly easily accomplished.
  • no separate measuring body is used, but the measuring body formed by the drilling tool, which is used to create the borehole.
  • the drilling tool contacts the borehole wall in the borehole and is thus centered within the borehole. It is therefore inevitably fitting in the borehole, so that the position of the drilling tool in the borehole reliably maps the position of the borehole in the appropriate place.
  • the drilling tool When using a common or integrated drilling tool and measuring body, it is preferred that the drilling tool is pulled out of the borehole and then the measuring cable attached to the drilling tool and the drilling tool is lowered again with the attached measuring cable for measuring the borehole in the borehole.
  • the drilling tool thus serves in a first method step for drilling hole production and in a second method step as a measuring body for measuring the borehole.
  • the drilling tool is preferably not rotationally driven.
  • the determination of the position of the drilling tool in the borehole preferably takes place when the boring tool is stationary.
  • the measuring cable is detached from the drilling tool, which also forms the measuring body, and stowed on the carrier unit. After pulling the drilling tool out of the borehole, the measuring cable is fastened to the boring tool, the boring tool is lowered again into the borehole and the measuring cable is tensioned.
  • the borehole is filled with a curable medium to create a pile in the ground.
  • a curable medium to create a bored pile wall.
  • the measuring body has a body with a diameter corresponding to the borehole. This ensures a suitable insertion and alignment of the measuring body in the borehole.
  • a suitable or defined position of the measuring body in the borehole is understood in particular to mean an arrangement in which the measuring body is defined, in particular centered, by contacting the borehole wall in the borehole cross section, so that due to the position of the measuring body it can be directly closed to the corresponding borehole section.
  • the measuring cable can be tensioned, for example, by the carrier unit having a mast and a carriage movably mounted on the mast, and a pivot point for the measuring cable being arranged on the carriage movably mounted along the mast.
  • the measuring cable can be tensioned between the articulation point on the carriage and the opposing articulation point on the measuring body.
  • the articulation point on the carriage can be formed for example by a fixed point, a pulley or a winch.
  • the carriage movable along the mast has a drill drive for rotationally driving a drill pipe.
  • the point of articulation for the measuring cable is provided on a non-rotating part of the carriage, for example on a carriage main body or a housing of the drill drive.
  • the carrier unit has a mast that the mast is pivotally mounted on a base and that by pivoting the mast either the drilling tool for creating the borehole or the separate measuring body in a borehole axis Borehole can be arranged.
  • the base of the carrier unit may be, for example, a carrier vehicle that can be moved on the ground surface.

  • the measuring cable is guided over a deflection roller, in particular on the carriage.
  • the measuring cable can be guided via the deflection roller on the carriage into the borehole axis.
  • the deflection roller on the carriage in this case forms a point of articulation of the measuring cable on the carriage.
