Definitions

  • the invention relates to a rotary drilling tool for creating a hole in the ground, with a base body, a removal device arranged on an underside of the base body, which has at least one hammer unit which comprises an axially reversibly driven hammer element, and a discharge line for discharging removed soil material and drilling suspension, according to the preamble of claim 1.
  • the invention further relates to a method for creating a hole in the ground with a rotary drilling tool, in which soil material is removed with a removal device on an underside of a base body of the rotary drilling tool and removed soil material and drilling suspension are removed by means of a discharge line, the removal device having at least one hammer unit, in which a hammer element is driven axially reversing, according to the preamble of claim 12.
  • a generic rotary drilling tool comes from the EP 2 592 214 A1 out.
  • several hammer units are provided with axially reversible hammer elements which are driven by compressed air. This creates a striking movement of the hammer elements, which means that hard ground, especially rock, can be removed.
  • Used compressed air can escape from a lower area of the hammer units, the compressed air being used to remove removed soil material and drilling suspension in the so-called air-lifting process.
  • the released compressed air can flow upwards through discharge lines. Soil material and drilling suspension are removed upwards from the borehole.
  • a drilling device which can be arranged within a support pipe and can clamp on the inside of the drill pipe to create the hole.
  • a rotary drive, a feed drive, a clamping device for clamping the housing in the support tube and other units for feeding and discharging suspensions are arranged within the drilling device. The soil material is removed using rotating cutting devices.
  • Drilling tools with rotating cutting teeth are suitable for working on soils of low or medium strength, particularly stripping soil material.
  • the WO 83/00183 teaches a hammer drill with a single drill head located at a lower end of the drilling device.
  • the US 4,790,391 A shows another rotary drilling device with an alternative cutting element advance.
  • a propulsive force is generated on the cutting element using a pneumatic piston.
  • the cutting element is axially displaceable on a guide, for example in the form of a splined shaft profile, which is acted upon by the piston.
  • a pumping device is provided on the working surface, which sucks the drilling suspension from the depth of the borehole.
  • the invention is based on the object of specifying a rotary drilling tool and a method for creating a hole in the ground, with which particularly good removal performance can be achieved, especially with hard ground material.
  • the object is achieved on the one hand by a rotary drilling tool with the features of claim 1 and on the other hand by a method with the features of claim 12.
  • Preferred embodiment variants are specified in the respective dependent claims.
  • the rotary drilling tool according to the invention is characterized in that a pumping device is arranged on the base body along the discharge line and that the pumping device is designed to pump out the removed soil material with drilling suspension through the discharge line.
  • a basic idea of the invention is based on the knowledge that, for good removal performance in hammer units with reversibly driven hammer elements, it is essential that these hammer elements hit the hard ground material as directly as possible. This allows the impact energy to be efficiently converted into selective overloads on the ground material which leads to the existing floor material flaking or breaking off.
  • the hammer unit can be driven in any way, for example using electrical energy or using a hydraulic fluid.
  • the at least one hammer unit is operated with compressed air, which is supplied via a supply line.
  • the compressed air is supplied from outside the borehole by a compressor, which is preferably arranged on the drilling device, through which a rotary movement is also applied to the rotary drilling tool.
  • a preferred development of the invention is that an outlet opening for used compressed air is provided at a lower end region of the at least one hammer unit.
  • the used compressed air therefore also escapes into the area in which the soil removal takes place.
  • the compressed air can flow upwards in the borehole filled with drilling suspension to remove removed soil material. According to the air-lifting process, the compressed air flowing upwards carries with it a certain amount of removed soil material and drilling suspension. This allows the flow generated by the pump device to be supported.
  • any suitable pump can be used as the pump device, in particular a screw pump.
  • One or more pumps can be provided.
  • a further preferred embodiment of the invention is that the hammer element has a vertically aligned piston, which is slidably mounted in a cylinder housing of the hammer unit.
  • the rotary drilling tool can have several hammer units which are designed in the same way.
  • the hammer units can in particular be designed in modular form from the cylinder housing with the piston mounted therein. The supply and discharge of compressed air is controlled in such a way that the piston moves up and down at a desired frequency.
  • the hammer units are arranged in a substantially cylindrical housing of the rotary drilling tool.
  • the pump device is arranged in a housing above the removal device.
  • the housing can extend a cylindrical base body with the removal device upwards.
  • the pump device is preferably arranged centrally within the upper part of the housing.
  • Energy for operating the pumping device can be supplied from outside the borehole via an energy supply line, in particular an electrical line or a pressurized fluid line.
  • a so-called rotary feedthrough or a rotary contact with an annular contact strip can be provided in a generally known manner, so that energy can be transferred to the rotating drilling tool from a fixed energy supply from the outside.
  • a connecting device for a drill pipe is arranged on an upper side of the housing.
  • the connecting device can in particular be a so-called Kelly box for connecting a Kelly drill pipe.
  • Other mechanical connecting devices for non-rotatably connecting the rotary drilling tool to a drill pipe can also be used.
  • a particularly efficient suction of removed soil material is achieved in that the pumping device is arranged on a central section of the discharge line and that the discharge line is divided into several discharge lines below the central section.
  • the pumping device is therefore arranged centrally on an approximately central section of the discharge line, whereby the suction power of the pump can be divided into several discharge lines below the central section.
  • At least one suction opening for sucking off the removed soil material is arranged on an underside of the base body.
  • Each suction opening is connected to a discharge sub-line, which leads to the central section with the pump device.
  • the processed soil material can be particularly reliably extracted over the entire drilling section and removed upwards via several suction openings.
  • a possible embodiment of the rotary drilling tool according to the invention is that the rotary drilling tool is designed as a full-cut drilling tool.
  • the downward-facing end face of the rotary drilling tool is essentially plate-shaped, with several hammer elements protruding to remove the existing soil. When the rotary drilling tool is rotated at the same time, particularly large areas of soil can be worked.
  • the rotary drilling tool is designed as a core drilling tool.
  • the hammer units are located as a removal device along an annular edge region of the base body.
  • a free receiving space remains in the middle to accommodate a core that forms during drilling.
  • the drill core can break off on its own after a certain length due to the transverse forces that occur during drilling.
  • an active device for breaking or processing the drill core can also be provided.
  • the core can be removed from the borehole using the rotary drilling tool or a separate core catcher.
  • an energy supply line is provided with which the pump device on the base body is supplied with energy, in particular electrical or hydraulic energy.
  • energy in particular electrical or hydraulic energy.
  • the pumping device can be operated particularly reliably.
  • the pump performance can also be easily adjusted possible depending on your needs.
  • the pumping device can also be done by tapping torque from the drill pipe.
  • the method according to the invention is characterized in that a pump device is arranged on a base body of the rotary drilling tool along the discharge line, with which the removed soil material with drilling suspension is pumped out through the discharge line to the outside of a borehole.
  • the method according to the invention is preferably carried out with the rotary drilling tool according to the invention, as described above.
  • the advantages described above can be achieved, particularly with regard to a high removal rate.
  • a preferred variant of the method according to the invention is that the hammer unit is operated with compressed air, which exits from an underside of the base body.
  • the escaping compressed air can support the removal of removed soil material with drilling suspension upwards into the discharge line.
  • particularly reliable suction is achieved in that the removed soil material and the drilling suspension are sucked out via several suction openings and several suction lines, which open into a central section on which the pumping device is arranged.
  • the pump's suction power is distributed over several partial suction lines and several drainage openings. This promotes reliable and quick removal of the removed soil material.
  • a first rotary drilling tool 10 is described below in connection with Figures 1 to 3 explained.
  • the rotary drilling tool 10 is designed as a core drilling tool with an annular arrangement of the removal device 20 around a central hollow core receptacle 16.
  • the removal device 20 has six identically designed hammer units 22 with a circular disk-shaped hammer element 24.
  • removal elements (not shown) are arranged, which are preferably tapered hard metal elements.
  • Suction openings 38 are arranged between the individual hammer units 22 for suctioning off the removed soil material with the surrounding drilling suspension.
  • the suction openings 38 are set obliquely in one direction of rotation in order to achieve the best possible material absorption.
