Definitions

  • the invention relates to a drilling device for civil engineering with in the drilling direction ending in a crown, rotatably driven and hollow drill pipe, the hollow of which is connected to a flushing device.
  • the invention also relates to a method for producing stabilizing columns or similar structures in the ground or the like. Soil masses in which a suspension with a binder is injected during a drilling process or after it - especially with a hydraulic binder with calcium silicates and aluminates that hardens under water.
  • Drilling devices of this type are known, for example, as rotary impact drills for rotating and impact drilling. These have a drill carriage as a machine frame with a rotary drill drive and a hammer motor, which interact with a feed drive and can be moved together with a drill rod on the drill carriage.
  • the drill pipe To manufacture the above-mentioned columns - in particular for lengths over 16 m - the drill pipe must be lengthened or shortened manually and the drill carriage for such an attachment and removal must be moved into a lateral rest position. When the extension is removed, injection material can flow out of the column that has already been produced. The one there The resulting cavity will usually fill up when the so-called jetting work is resumed. If this backfilling is not completely successful due to broken ground, there is a localized constriction in the area of the boom change.
  • the inventor has set itself the goal of eliminating the identified shortcomings and improving such a drilling device and the manufacturing method described above.
  • An inner rod bearing the crown and connected to the flushing device is surrounded in a section of its longitudinal extent by a tubular jacket and forms an annular space with the latter.
  • a tubular jacket For this purpose, it has proven to be advantageous to provide the tubular casing with its own rotary drive and preferably to design the inner linkage and tubular casing to be rotatable in opposite directions to one another.
  • the tubular casing ends at a distance from the crown of the inner rod with an annular crown directed towards the latter, which defines an opening and which conveys excess mixture from the bottom of the borehole; according to the invention Annulus connected to a discharge device.
  • the tubular casing has at least one radial opening which connects the annular space to a discharge housing.
  • this discharge housing surrounds a section of the annular space which is widened in cross section; this catching section for the material that is extracted against the direction of drilling contains the breakthrough (s).
  • the suspension reaches radial pressure nozzles in the hollow of the inner rod up to close to the drill bit, which can be closed by a check valve;
  • the inner linkage is provided in its section protruding from the tubular jacket with at least one of these nozzles — connected to the hollow of the inner linkage and approximately radially directed — wherein several nozzles can be distributed axially offset around the circumference of the inner linkage.
  • two coaxially arranged and mutually counter-rotating tube elements - which have crowns in the direction of drilling - produce an eccentric rotation at the point of drilling, the wall thickness of the outer tube element being pre-cut with the crown of the inner rod assembly.
  • the suspension is pressed with high pressure between the two crowns radially to the drilling axis from the inner rod into the surrounding growth.
  • the suspension is introduced into the soil for 3 to 6 minutes, in particular 4 to 5 minutes, per meter of column length and then excess suspension / soil mixture is drawn off through the crown located at the back in the direction of drilling.
  • the risk of “jamming” of the nozzle jet is substantially lower than in the case of uncased jetting due to the counter-rotation of the inner linkage and the piping or pipe jacket and the short distance between the nozzle and the pipe jacket.
  • so-called rotary impact screws can be used as inner rods in soils with a high clay content at no additional cost. This would ensure the functionality of the system even in the event of a very thick backflow.
  • the intended speed of 10 to 15 rpm is low compared to conventional values, but promises better jetting results.
  • the speed can be regulated continuously in the drilling device according to the invention; it is also possible to fundamentally vary the retraction speed during the jet of the individual pile.
  • the formation of the column is to be continuously monitored by monitoring and recording the most important parameters, specifically within the following parameters: * Quantity measurement 0 to 200 rpm * Pressure measurement 0 to 1000 bar * Drilling depth according to vote * Speed of the jet nozzle option
  • an inner rod or inner tube 12 of the drill rod 10 is equipped at one end with a flushing head 14 together with a hose connection 16, through which liquid reaches the hollow 13 of the inner rod 12.
  • the latter bears a striking crown 18 with an axial passage 19 and a cutting edge 20, which is preceded by a check valve 22 in the drilling direction X in the rod axis A. This is closed by the pressure of the liquid and with it that passage 19.
  • the inner rod or inner tube 12 of an outer diameter d of 90 mm here is uneven by a tubular jacket 24 of length and an outer diameter e of 133 mm, which delimits an annular space 26 with the inner rod 12.
  • This tubular jacket 24 ends crownwise at a distance b from the free end of the striking crown 18 with an annular crown 28. Its mouth 30 receives reflux material which flows through the annular space 26 against the drilling direction x to an annular slot 32 or the like which partially surrounds the inner rod 12. Breakthrough migrates and through this into the housing 36 of a discharge line 38.
  • a catch section 34 of length n of the tubular jacket 24 is rotatably supported in cross-section.
  • a rotary drive 40 which actuates and surrounds the inner linkage 12 and to which a sleeve extension 25 of the tubular jacket 24 with a rotary drive 42 is adjacent for this towards the crown.
  • a flange 44 of that sleeve end 25 sits on a counter flange 45 of the tubular jacket 24.
  • radial nozzle holes of a nozzle holder 48 of the inner rod 12, which is provided near the check valve 22, are indicated, at 50 nozzle or jet jets emerging from the nozzle holes 46 of the inner rod 12.
  • the inner rod 12 rotates clockwise, the tubular jacket 24 in the opposite direction. This counter-rotating rotation creates an eccentric rotation in the drilling starting point, which means that the striking crown 18 of the inner rod 12 pre-cuts the wall thickness of the tubular casing 24, also referred to as piping. This also allows smaller boulders to be drilled through with piping 24.
  • a major advantage of this procedure is the high directional accuracy. Due to the rotary pre-cutting, stones or blocks that are rubbed off are cut; the deviation from the drilling axis A is much smaller than with rotating cutting.
  • the following drilling accuracies can be guaranteed: Total drilling length to 12.00 m 1.0% 0 to ⁇ 12 cm 12.00 - 16.00 m 1.5% ⁇ 12 to ⁇ 24 cm 16.00 - 20.00 m 2.5% ⁇ 24 to ⁇ 50 cm.
  • the central flushing hole is closed by means of a steel dome (not shown) after the desired drilling depth has been reached.
  • a hydraulic binding agent such as cement
  • An example of operating parameters for column diameters of approximately 600 mm includes: - pump pressure about 500 bar - nozzle diameter 2 x 2.00 mm - retraction speed approx. 4 - 5 min / ml (steps of 4 cm in approx. 10 sec.) - revolution per minute 10 - 15 rpm. - W / Z factor 1.1 - 1.25
