Definitions

  • the invention relates to a method for drilling holes in the ground or rock, in particular for the production of grout anchors, and a drilling device for performing this method with the features of the preamble of claim 1 and 3 respectively.
  • Drilling devices for making holes for grout anchors in the ground or in the rock have a caterpillar vehicle with a carriage which is articulated on articulated arms in all spatial axes.
  • a magazine for several shots of the drill pipe is provided on such a drilling device.
  • the drive for the drill pipe with drill bit, which can be raised and lowered on the carriage, is mechanically shot by shot of the drill pipe from this magazine. After drilling the holes and before inserting the grouting anchors, the shots of the drill pipe are transferred back into the magazine. It is disadvantageous that such a drilling device cannot be used to drill a borehole, which can also move piping to support the borehole wall.
  • a drill which has a single magazine in which the shots of the drill pipe and the borehole casing are arranged concentrically one inside the other, see US-A-3734209.
  • the disadvantage here is that the borehole rod sections and borehole casing sections are unnecessarily long.
  • the concentrically arranged shots of the drill pipe and the borehole piping are taken together from the magazine for drilling the hole, for example by a double-head drive, and transferred into the borehole. After drilling the borehole, the borehole linkage must be transferred shot by shot into the magazine before inserting the grout anchor.
  • the magazine After inserting the grout anchor, the magazine is shot after shot of the drill string removed and transferred back into the magazine in a concentric arrangement with the drawn borehole casing section. Returning the shots of the drill pipe and the well casing to the magazine is cumbersome and time consuming. A special drive for the shots is also required.
  • the invention offers the advantage that the shots of the drill pipe and the borehole piping can be taken separately from one another and in chronological succession from a magazine and can be transferred back into this after drilling the hole for a compression anchor.
  • the supply of the shots of the drill pipe and the casing pipe in the magazine is simplified according to the invention.
  • separate magazines are used for the shots of the drill pipe and the well casing. These are preferably on the drill arranged one above the other.
  • the shots are successively removed from the magazines moved into the aligned working position and then back into the outer position. They are transferred by the drives in a concentric arrangement into the drilling position, where they are connected to the end of the shots for the drill pipe and the borehole casing located in the borehole.
  • the drill pipe is transferred shot by shot into the associated magazine.
  • the grouting anchor is then inserted into the still cased borehole.
  • the borehole piping is then drawn shot by shot and transferred to the associated magazine.
  • the magazines swivel into the working position and then back into the starting position.
  • the drilling device 1 can have a tracked vehicle 2 with hydraulically actuated articulated arms 3.
  • a carriage 4 which can be raised and lowered and can be moved in all spatial axial directions, is articulated thereon.
  • the drive head 7 of this drive 6 is used for rotary and / or impact drive for the drill pipe with drill bit.
  • the drive head 8 of this drive 6 is used for rotary and / or impact drive for the piping, if necessary with a drill bit of the borehole, if e.g. a double head drive is used.
  • With the duplex drive the borehole piping and the borehole rods are rotated and / or struck at the same time.
  • the drill drive 6 is driven by a feed drive 9 on the carriage 4 so that it can be raised and lowered.
  • a breaking, clamping and guiding device 11 which is used to hold, unscrew and close the connections, e.g. Threaded connections, the shots of the drill pipe and the downhole tubing is used.
  • connections e.g. Threaded connections
  • Bayonet connections are used.
  • magazines 12 for the shots 13 of the drill pipe are preferably arranged on both sides next to the carriage. These magazines 12 are turret-shaped.
  • the magazines 12 can be rotated about their central axis 14. They take several shots distributed around the circumference, freely removable from the outside.
  • Each magazine can be swiveled inward into a working position (not shown) from the external storage position according to FIG. 3 via a swivel drive about the swivel axis 15.
  • the drive head 7 take the aligned, assigned shot 13 of the drill string. After taking over the assigned shot 13, the magazine swings outwards again into the supply position.
  • magazines 16 for the shots 17 of the piping for the borehole are arranged in the same way on both sides of the mount 4.
  • These magazines 16 are also turret-shaped. They are rotatable about the central axes 18. They take several shots of the piping for the borehole, which can be freely removed from the outside, distributed around their circumference.
  • Each magazine can be transferred from an external supply position into a working position via a swivel drive about a swivel axis 19, in which the assigned section of the piping is aligned with the drive head 8.
  • the drill drive 6 After taking a shot 13 by the drive head 7, the drill drive 6 is moved downwards.
  • the drive head 8 takes over the aligned shot 17 of the borehole piping from the magazine 16 in the working position, which coaxially surrounds the shot 13 of the drill pipe as a tube.
  • the drill drive 6 then moves downward after the magazine 16 returns to its supply position.
  • the shots 13 and 17 are fixedly connected to the drill pipe or casing located in the borehole in a known manner using the breaking, clamping and guiding device 11.
  • the rotary and / or impact drive of the drilling drive 6 is then actuated.
  • the drill pipe is dismantled shot by shot.
  • the shots 13 of the drill pipe are then moved to the height of the magazine 12.
  • the magazines 12 are swung in.
  • the shots 13 are then transferred into the magazines 12 in a suitable position.
  • the magazines are then returned to their external storage position.
  • the grout anchor is then installed in the still cased borehole.
  • the piping is then dismantled shot by shot.
  • the shots 17 of the piping are transferred into the magazines 16 in a similar manner as described above.
  • the magazines do not have to be provided on the drill itself. They can also be placed in secondary positions, e.g. other vehicles.
  • the respective magazine 13 can have a locking device 20 according to FIG. 4, which is able to hold the shot 13 of the drill pipe in the working position so that it cannot rotate, so that the drive head 7 with this shot 13 e.g. is connected by screwing.
  • the weft 13 can have a thread 43 in the upper region, which is screwed to the drive head 7. 4, 6 and 7, the locking device 20 consists of two elements 21 and 22, each having a slide slope 24 and 25, which cooperate with each other.
  • the first element 21 is provided below a guide 27 with a key-shaped locking device 23, the front one Area is able to engage in a corresponding key surface 42 on the outer circumference of the weft 13. Below this key-shaped locking device 23, the first element 21 of the locking device 20 is designed such that it can slide past the outer circumference of the shot 13 on both sides.
  • the second element 22 is attached to a carriage 44, which is arranged in the central area Z of the respective magazine 12 or 16 on its central axis 14 or 18 so as to be vertically displaceable.
  • This carriage 44 is connected to a piston-cylinder unit 26, which is supported in the central area Z of the respective magazine.
  • Fig. 6 shows the locking device 20 in the retracted position.
  • the piston-cylinder unit 26 is actuated, the carriage 44 moves upwards on the axis 14, whereby the first element 21 is displaced to the right in the direction of the arrow in the direction of the arrow via the second element 22 and the sliding surface 24, and until the front of the key-shaped locking device 23 engages in the key surface 42 and thus holds the shot 13 which is in the working position in a rotationally secure manner.
  • the guide 27, which is fixedly connected to the central area Z, serves as a counter surface during the displacement process of the first element 21.
  • the drive head 7 can be shut down from above and connected to the weft 13 in a rotationally secure manner via the thread 43.
  • the piston-cylinder unit 26 is again acted upon, so that the locking device 20 moves back from the position shown in FIG. 7 to the position shown in FIG. 6.
  • the shot 13 is moved via the drive 6 or the drive head 7 down into the area of the magazine 16 in which the shots 17 of the piping are arranged.
  • These magazines also have a lock 20, as in the aforementioned embodiment, whereby in the same way the shot 17 of the piping in the working position is connected to the drive head 8 in a rotationally secure manner.
  • the drive heads 7 and 8 are released from the respective shots 13 and 17 via the device 11 and sweep back to their starting position.
  • the corresponding shots are moved back into the area of the magazines assigned to them after they have been loosened beforehand by the device 11 or by means of a screw connection.
  • the corresponding locking device 20 again comes into operation and holds the respective shots 13 and 17 in the working position in the respective magazine area until the connection between these shots and the drive heads 7 and 8 assigned to them are broken again. The shots are thus moved back from the working position into the storage position within the magazine 12 or 16 assigned to them.
  • the respective central axis 14 can be provided with a roller guide 28.
  • this roller guide 28 has two coaxially arranged rollers 30 and 29, which surround a guide slot 31 on both sides.
  • the respective shot 13 or 17 can thus be guided well between the rollers 29 and 30 assigned to them within the guide slot 31, so that there is an improvement in the mounting.
  • the tracked vehicle 2 is provided in the area of the carriage 4 with articulated arms 33 and 34 with a lifting and lowering working platform 32.
  • These articulated arms 33 and 34 are part of a four-bar linkage with a coupling 39 and a bearing 45, which is arranged on the tracked vehicle 2 next to the articulated arms 3.
  • the work platform 42 is attached to the rocker 39.
  • a piston-cylinder unit 41 one arm of which is arranged on the housing, while the other arm is connected to the articulated arm 33. If this piston-cylinder unit 41 is actuated, the two articulated arms 33 and 34 pivot upward, so that the work platform 32 moves in the direction of the arrow via the coupling 39.
  • the coupling 39 is always held in a position which ensures that the working platform 32 is always in a horizontal plane.
  • the two articulated arms 33 and 34 are designed telescopically.
