Definitions

  • the invention relates to a drilling device for a high-pressure injection method with a first drilling drive and with a channel rod, which has at least one injection nozzle for the discharge of a high-pressure suspension and a drilling head at its end.
  • the invention further relates to a drilling method using this drilling device.
  • High pressure injection processes are used in civil engineering for the production of supporting and sealing walls in the ground, underpinning bodies or plate-shaped bodies for base seals.
  • a drill bit attached to a rod is primarily introduced with external rinsing.
  • a concrete-cement suspension is injected into the soil under high pressure via a horizontally oriented nozzle located in the lower part of the drill pipe.
  • By rotating the drill pipe it is possible to produce column-shaped injection bodies during withdrawal, the size and strength of which are determined by the choice of drawing speed, pump pressure and nozzle diameter.
  • the wall and plate-shaped injection bodies are obtained by connecting several columns.
  • the invention has for its object to provide a drilling device and a drilling method of the type mentioned, with which the accuracy of the holes is improved.
  • the invention has the advantage that the drilling of the channel rod is made easier by the drilling aid of the outer tube.
  • the guidance of the outer pipe ensures a more precise sinking.
  • a deviation of the channel rod from the predefined direction of propulsion can be effectively countered.
  • a preferred embodiment of the drilling device is that the outer tube is double-walled to form a feed channel for the flushing medium, which is provided with outlet openings in the area of the drill bit.
  • annular space is present between the outer tube and the channel rod. Excess injection sus pension can escape unhindered. This prevents uncontrolled injection suspension from causing uplifts in the ground. In addition, there is no risk of blockages that could otherwise occur when the borehole wall collapses. Since the distance between the outer tube and the duct linkage can be freely selected, an optimal adjustment to the drilling base can be made by appropriate selection of the outer tube diameter.
  • the channel linkage includes a feed for additional flushing medium for the drill head.
  • the drilling method is preferably developed in that the outer tube and the channel linkage can be rotated independently of one another with respect to their direction of rotation and / or their speed.
  • the propulsion of the channel rod and the outer tube are independent of one another.
  • FIG. 1 a drilling tool and the associated linkage is illustrated during a drilling phase.
  • the Bohr Tool consists of a double-walled outer tube 1 with a drill bit 2 at the end.
  • a separate, independent channel linkage 3 with a drill head 4 is arranged coaxially inside the outer tube 1.
  • both the outer tube 1 and the channel linkage 3 are each provided with a separate drill drive, which can be mounted above the ground, for example, on a carriage.
  • the outer tube 1 and the rod 3 are drilled simultaneously, the directions of rotation being able to be in opposite phases, as the arrows 6 indicate. It is also possible to provide different speeds due to the two independent drilling drives. The choice of the directions of rotation and the speeds is selected depending on the properties of the soil 5 with a view to optimal propulsion.
  • a flushing medium for example bentonite suspension, is introduced as a drilling aid for the outer tube through a feed channel 7 which is formed between the outer wall 8 and the inner wall 9 of the outer tube.
  • the necessary pumping equipment and storage tanks are installed on the surface of the earth.
  • the flushing medium In the area of the drill bit 2, the flushing medium reaches the soil acted upon by the drill bit 2 via outlet openings 10, which are distributed over the circumference of the outer tube 1.
  • the escaping flushing medium is provided with the reference number 11 in the figure.
  • the bottom of the drill is further processed using the drill head 4.
  • the drill head 4 is also provided with outlet openings (not shown) for further flushing medium which is supplied in the interior of the channel rod 3. It acts in the area 13 in front of the drill head 4.
  • FIG. 1 shows a configuration in which the outer tube 1 leads the channel rod 3. Depending on the geology, it can be the same be appropriately useful to guide the channel linkage 3 in front of the outer tube 1 or at the same height of the outer tube 1.
  • the linkage 3 has at least one injection nozzle 12, which is oriented essentially horizontally. It is connected in the interior of the channel linkage 3 via a feed line (not shown) to a high-pressure pump on the surface of the earth, via which a high-pressure suspension is introduced, as the following description explains.
  • the rod 3 After reaching the final depth, the rod 3 is brought into a position in which the injection nozzle 12 or, if appropriate, a plurality of such injection nozzles are in front of the drill bit 2. This position is illustrated in FIG. 2.
  • the high-pressure suspension 14 is then injected into the soil 5, a cylindrical injection body 15 being produced by rotating and pulling the drill pipe 3.
  • the outer tube 1 and the channel linkage 3 is partially shown in longitudinal section along the longitudinal center line 17. It can be seen that the channel linkage 3 consists of two coaxial tubes, the outer channel tube being provided with the reference number 18 and the inner channel tube with the reference number 20. The suspension is passed to the injection nozzle 12 via the inner sewer pipe 20.
  • this additional flushing medium can also be used to flush out the annular space 16.
  • the outer sewer pipe 18 is provided with at least one flushing nozzle 22, which directs a liquid jet from the bottom to the top. This measure ensures a continuous backflow in the annular space 16 and prevents clogging or partial narrowing of the annular space 16.
  • the emerging further flushing medium flows upward in the direction of the earth's surface and supports the transport of the drilling material which has been released from the drill bit 2 and the drill head 4 (FIG. 1) under the additional influence of flushing medium. It prevents this drill material from assembling or clumping in the annular space 16.
  • flushing nozzle 22 it may be sufficient to have a single flushing nozzle 22. If several such flushing nozzles are distributed along the circumference of the outer sewer pipe 18, the continuous transport of drillings to the surface of the earth can be further improved. In particular in the case of longer duct linkages 3, the flushing of the annular space 16 is supported when flushing nozzles are stacked vertically are arranged along the channel rod 3.
