Definitions

  • the invention relates in a first aspect to a pipe bunker for receiving concrete for filling a borehole.
  • the invention relates to an apparatus and method for extracting a multi-piece drill pipe from a wellbore and for filling the wellbore.
  • a device for producing columns of material in the soil has a sinking unit with deep vibrator and material delivery pipe.
  • a feed lock is arranged, which is sealed pressure-tight on the one hand with respect to the pressure chamber formed in the conveyor tube during operation and on the other hand with respect to the environment.
  • a lock door is provided on the bottom side of the loading lock.
  • the US 5,647,690 discloses a generic tube bunker, which is provided for filling cavities in the ground for pillar preparation. On the bottom side of the pipe bunker a pipe is provided, which is retracted into the ground. During the subsequent pulling of the pipe sand from the bunker is filled through the pipe in the resulting cavity. A valve is provided on the tube bunker to stop the flow of material from the bunker through the tube after a column has been filled.
  • the object of the invention is to provide a device with which the filling of a borehole when pulling out of the drill pipe is significantly facilitated.
  • an apparatus and a method for extracting a multi-part drill pipe from a borehole and to fill the borehole to be specified.
  • a pipe bunker for receiving concrete for filling a borehole which has a container body with at least one inlet opening for filling the concrete and with an outlet opening for the outlet of the concrete, wherein the container body is formed in the region of the outlet opening for connecting a drill pipe and wherein in the region of the outlet opening, a closure device for closing the outlet opening is provided.
  • a tubular bunker consisting essentially of a container body with an inlet opening for filling the concrete and an outlet opening for the exit of the concrete and the is formed in the region of the outlet opening for connecting a drill pipe.
  • a first significant advantage of such a tubular bunker is the fact that the subsequent delivery of the concrete so special reliably can be accomplished.
  • the tube bunker according to the invention is particularly simple and can therefore be manufactured inexpensively.
  • the container base body has a substantially cylindrical shape with an inlet-side and / or outlet-side conical end region.
  • the container base body can then be made of a steel tube, for example.
  • the diameter of the container main body may be twice as large to three times as large as that of the drill pipe.
  • the angle of the conical end region on the outlet side is preferably selected so that the liquid concrete can flow off easily. Appropriately, this angle is about 45 °. Since this requirement is not met in the inlet-side conical end portion, this end portion can be kept flatter. As a result, with substantially the same external dimensions, a higher storage capacity of the tubular bunker can be achieved.
  • connection to the drill pipe or the connection to a concrete supply line is particularly simple if an inlet nozzle is provided on the inlet-side end region and / or an outlet nozzle is provided on the outlet-side end region.
  • the outlet nozzle in order to transfer the drilling torque to the drill pipe via the pipe bunker, is non-rotatably connected to the drill pipe.
  • the torque of a rotary drive can be transmitted to the tube bunker, when also the inlet nozzle is designed for rotationally fixed connection to the rotary drive.
  • Such non-rotatable connections can be provided by suitable internal or external teeth.
  • the closure device is designed as a pivotable flap. This is inexpensive and therefore inexpensive to implement and also ensures high reliability.
  • the flap is pivotable about a centrally arranged axis. Even with pending concrete pressure then the flap can be opened and closed with a minimum of forces.
  • the closure device can in principle be operated in any manner.
  • the closure device can be actuated hydraulically or mechanically in a particularly simple and reliable manner.
  • the device according to the invention for extracting a multi-part drill pipe from a borehole and for filling the borehole has a pipe bunker according to the invention, as described above, and a lifting device for holding, raising and lowering the pipe bunker and a drill pipe possibly attached thereto.
  • a device which is particularly suitable for carrying out the method described below, the extraction of a multi-part drill pipe from a borehole and the filling of the borehole with concrete is particularly simple.
  • the apparatus may conveniently comprise a fixing device for holding the drill pipe.
  • a fixing device for holding the drill pipe.
  • This may be, for example, a hydraulic gripping or clamping device, which is actuated if necessary.
  • a hydraulic device is expediently provided for actuating the closure device of the tubular bunker and / or for actuating the fixing device.
  • the lifting device is hydraulically or mechanically actuated.
  • a further preferred variant is characterized in that the lifting device has a carriage which is arranged displaceably on a vertical guide.
  • the tube bunker can be rotatably mounted.
  • a rotary drive for the drill pipe is arranged on the carriage, which in turn is rotatably connected to the tubular bunker.
  • the drill pipe together with an end-mounted pipe bunker is pulled out of the borehole until a boring element is exposed.
  • the tube bunker is then closed and the exposed drill pipe element is released from the tube bunker and, where appropriate, from further drill pipe elements still located in the wellbore.
  • the tube bunker is then moved down and connected to the next drill pipe element. Then the tube bunker is opened again so that concrete can flow through the drill pipe into the borehole.
  • a core idea of the method according to the invention can be seen in not extracting a multi-part drill pipe as a whole from the borehole but rather only so far until a single pipe element is exposed and can be removed.
  • the tubular bunker according to the invention can be used particularly advantageously.
  • a significant advantage of the method according to the invention is the fact that the design effort to pull out the drill pipe can be significantly reduced, since in principle only one lifting height is necessary, which corresponds essentially to the length of a drill pipe element. In this way, significant costs can be saved.
  • the simultaneous filling of the concrete also prevents the penetration of water into the borehole.
  • a downhole from the lifting device dissolved or to be solved drill pipe is held while the exposed drill pipe element is removed. In this way, a sinking or sinking of the drill pipe can be prevented in the borehole.
  • connection between pipe bunker and drill pipe can for example be designed so that the release of the pipe bunker from the drill pipe can be done by a short turn against a drilling direction.
  • FIG. 1 An embodiment of a tubular bunker 10 according to the invention is in connection with the Fig. 1 and 2 described. Equivalent components are identified by the same reference numerals.
  • the tubular bunker 10 essentially consists of a container base body 12, to which conical end regions 28, 30 adjoin on the inlet side and outlet side.
  • liquid concrete can enter the tube bunker 10 via an inlet opening 14 and exit from an outlet opening 16 into a drill pipe.
  • Adjoining the inlet-side conical end region 20 is an inlet connection 32, which is provided with external teeth 33 for rotationally fixed connection to a rotary drive.
  • a plurality of openings 17 are formed in the inlet-side conical end portion 28, which can serve to fill the tube bunker 10 with concrete but also for venting.
  • the outlet-side end portion 30 has a steeper angle compared with the inlet-side tapered end portion 28, thereby ensuring a safe drainage of liquid concrete.
  • the outlet-side conical end region 30 is adjoined by an outlet connection 34, in which a closure device 18 for closing the outlet opening 16 is integrated.
  • the closure device 18 shown there is designed as a flap closure and consists essentially of a tubular base body 19 in which a flap 26 is pivotally mounted about a central axis 36.
  • the tube body 19 may itself be designed as a connection piece for the tube bunker.
  • an adjusting device 42 is provided laterally on the tubular base body 19.
  • a total of six stop pins 44 are positioned at the same angular intervals on the inside of the tubular base body 19. The exact position of these stop pins 44 is particularly clear from the Fig. 4 and 6 seen.
  • two stop struts 46 are also arranged in the interior of the tubular body 19. This is especially clear in the Fig. 3 . 4 . 6 and 7 shown.
  • a limitation of the movement of the flap 26 in the closed and / or open position can of course be accomplished with differently shaped stop elements.
  • the stop struts 46 in particular a possible fluttering of the flap 26 is prevented at high concrete throughput.
  • FIG. 8 an embodiment of a device 40 according to the invention is shown schematically.
  • An essential component of the device 40 according to the invention is a pipe bunker 10 according to the invention, which is non-rotatably connected to a rotary drive 56.
  • the tubular bunker 10 is connected via the rotary drive 56 with a lifting device 50.
  • the rotary drive 56 is attached to a carriage 54 as part of the lifting device 50.
  • a vertical guide 52 of the carriage 54 is adjustable in the vertical direction by means of a hydraulic system.
  • a drill pipe element 21 is rotatably arranged as part of a drill pipe 20 via a coupling 23.
  • the coupling 23 can be released by turning it against a rotational direction of rotation.
  • Fig. 8 a situation is shown in which the drill pipe 20 is partially in a borehole 22 introduced into the ground 60.
  • the drill pipe 20 is now lifted with the aid of the lifting device 50 until the drill pipe element 21 is completely above the ground 60 and thus can be removed.
  • the tube bunker 10 is closed by means of the flap 26 of the closure device 18, shown schematically, so that no liquid concrete 24 can escape more from the tube bunker 10.
  • the drill pipe element 21 is released from the pipe bunker 10 and the subsequent drill pipe element 25.
  • the drill pipe element 25 can then be conveniently held by means of a fixing device to prevent it sinking into the borehole 22.
  • the tube bunker 10 is lowered by means of the lifting device 50 and connected to the next drill pipe element 25.
  • further concrete 24 may flow into the wellbore 22 and the above steps may be repeated until the wellbore 20 is completely withdrawn from the wellbore 22, possibly with the drill bit, and the wellbore 22 is completely filled with concrete 24.
  • the extraction is Of multi-part drill pipes from a well and the simultaneous filling of the borehole with concrete in a particularly simple manner and with significantly reduced expenditure on equipment possible and it can therefore be saved to a considerable extent costs.
