Definitions

  • the invention relates to a guide frame for guiding a milling device and a method for anchoring a pipe in the ground.
  • the pile tubes are usually rammed by means of suitable piling in the seabed. Since the seabed is usually sufficiently soft, a ramming is basically possible even with relatively large pipe diameters. However, it may happen that there are hard rock layers or boulders in the soil, which make further ramming of the pipe considerably difficult or even impossible. Especially for pipes with a large diameter such rock layers or boulders can lead to considerable problems in anchoring.
  • the invention is therefore based on the object to provide a device by means of which the anchoring of a pipe in the ground can be supported.
  • the invention is also based on the object of specifying an economical method for anchoring a pipe in the ground.
  • the guide frame according to the invention for guiding a milling device within a tube inserted into the ground comprises a frame which is insertable into the tube and has a guide along which the milling device is displaceable, a clamping device for clamping and fixing the frame in the tube and an adjusting device with which the milling device is adjustable in a transverse direction to the tube axis within the tube.
  • the inventive method for anchoring a pipe in the ground comprises the steps of: ramming the pipe into the ground, inserting a guide frame with a milling device mounted therein into the pipe and lowering within the pipe, tightening the guide frame within the pipe and removing soil within the pipe Tube by rotationally driving at least one cutting wheel of the milling device and axial lowering of the milling device within the guide frame.
  • the guide frame according to the invention serves to guide a milling device axially within a pipe partially introduced into the ground in order to excavate and / or shred soil material inside or below the pipe.
  • the introduction, in particular ramming, of the pipe into the ground can hereby be supported by, for example, crushing and / or removing hard material below the pipe, which impedes further driving in of the pipe, by means of the milling device.
  • a hard material may be, for example, a foundling, which projects below the tube into the tube cross-section. After removal of the hard material or foundling, the pipe can be further introduced into the soil.
  • the pipe may in particular be a supporting mast to be anchored in the ground, for example for a wind energy plant, preferably an offshore wind energy plant.
  • Such masts may have diameters of several meters, for example five meters or more.
  • the mast tapers upwards, in particular above the water surface, since there lower forces act.
  • the milling device can in particular be a trench wall cutter with horizontally mounted cutting wheels and a substantially rectangular milling cross section. Such milling devices are well known and are commonly used for creating Frässchlitzen in the ground.
  • such a standard milling machine can also be used for excavating soil within a pipe introduced into the soil.
  • an essential aspect is that the milling device has a smaller cross-section than the inner cross section of the tube section introduced into the bottom in order to be able to lift it into the tube through the tapered upper section.
  • a first basic idea of the invention is to guide the milling device axially within the tube, in order to remove soil by means of the smaller-diameter milling device in a defined subarea of the tube cross-section and reliably avoid damage to the tube.
  • the milling device is axially displaceably mounted on a frame of the guide frame, so that it can be lowered relative to the frame during the milling process.
  • the frame in turn can be firmly clamped within the cross section of the tube, so that a reliable guide is realized.
  • Another basic idea of the invention is to be able to adjust the milling device, in particular between individual milling operations, within the tube in the transverse direction.
  • the adjustment provided for this purpose thus moves the milling device in a direction transverse to the tube axis pipe cross-sectional plane.
  • This is based on the fact that the cross section of the milling device is smaller and usually has a different shape than the inner cross section of the tube in which the milling device is used. Due to the adjustment of the milling device within the tube targeted different portions of the pipe cross-section can be excavated. By repeatedly displacing the milling device, it is even possible to excavate soil in the region of the entire pipe cross-section.
  • the adjusting device comprises a turning device, by means of which the milling device is rotatable within the tube.
  • a turning device by means of which the milling device is rotatable within the tube.
  • an inner frame of the guide frame, on which the milling device is mounted are rotated relative to an outer frame braced in the tube.

  • the adjusting device comprises a displacement device by means of which the milling device is displaceable transversely to the tube axis.
  • a displacement device by means of which the milling device is displaceable transversely to the tube axis.
  • the frame is clamped by means of extendable clamping or spreading arms in the tube, wherein the clamping arms allow different radial positioning of the Fräsrahmens within the tube cross-section.
  • opposing clamping arms can be provided, which are selectively different, so non-symmetrical to each other, are extendable.
  • At least one roller is provided, which rests for rotating the frame with the milling device to the tube axis on a tube inner wall of the tube and rolls.
  • the at least one roller is designed as a support roller, which is supported on the pipe inner wall and so carries the guide frame.
  • the support roller can be preferably held by frictional engagement on the pipe inner wall.
  • the support roller can be pressed against the pipe inner wall and thus forms a part of the clamping device, with which the guide frame is clamped in the pipe. In this way, the guide frame can be rotated during the clamped state in the tube.
  • several rollers are provided.
  • At least one rotary drive is provided, with which the at least one roller for generating a rotational movement of the frame can be driven.
  • the at least one roller for generating a rotational movement of the frame can be driven.
  • the at least one roller for contacting the pipe inner wall relative to the frame frame is radially extendable.
  • the radially extendable roller allows on the one hand a distortion of the frame within the tube and on the other hand an adaptation to different pipe cross-sections.
  • the clamping device preferably has at least one clamping element, which is radially extendable relative to the frame.
  • a clamping element for example a clamping or clamping jaw, a hydraulic cylinder may be provided.
  • the clamping element can also be formed by the support roller, so that in the clamped state, a rotation of the guide frame is possible.
  • the frame has a stop by means of which the guide frame can be supported on the milling device.
  • the guide frame can be put on the milling device and supported by this or wear.
  • a cable suspension is provided on the milling device, with which it can be hung on a support device. This makes it possible to provide for lowering or raising the guide frame no separate lifting device.

  • the cutting device for undercutting a region below a tube wall of the tube can be arranged and guided obliquely within the tube.
  • the entire guide frame within the tube obliquely, that is transversely to a longitudinal axis of the tube can be arranged.
  • an obliquely routable milling device can be used to mill off an area underneath the pipe wall in order, for example, to crush or remove hard rock like a foundling there.
  • the guide frame preferably comprises differently extendable clamping arms.
  • At least one roller is provided, which rolls upon rotation of the frame around the tube axis on a tube inner wall of the tube and that the at least one roller is mounted radially extendable on a relative to the frame radially extendable clamping element.
  • a fixed tension or a tension in which the guide frame is rotatable within the tube, can be set.
  • the frame can be firmly clamped inside the tube by means of the radially extendable clamping element, for example a clamping jaw.
  • the roller in particular support roller, can be used for tensioning the guide frame.
  • the roller mounted on the tensioning element can be extended radially relative to the tensioning element so that it projects radially beyond the contact surface of the tensioning element.
  • a hydraulic connection can be provided on the guide frame, which can be coupled to a hydraulic connection of the milling device.
  • the guide frame can thus be supplied with hydraulic fluid via the milling device, which is connected to a hydraulic unit. A separate hydraulic supply of the guide frame is then not required.
  • the invention further relates to a device for removing soil within an at least partially introduced into the ground or rammed pipe.
  • the device comprises a guide frame according to the invention and a milling device which is mounted on the guide frame and comprises a milling frame and at least one cutting wheel mounted on the milling frame.

  • multiple adjustments of the milling device within the tube cross-section can be using the smaller diameter milling device approximately cancel the entire cross section of the tube.
