Definitions

  • the invention relates to a method for operating a horizontal bore and a horizontal boring device.
  • Horizontal drilling devices are used to bring in trenchless construction methods disposal lines in the ground or already existing old lines trenchless exchange.
  • Horizontal drilling devices are widely used, in which a drill head is initially driven obliquely into the soil by means of a drill pipe and, starting from a drilling carriage positioned on the earth's surface, until the drill head reaches the desired drilling depth. Then the drill head is reversed to the horizontal to perform the actual horizontal bore.
  • the target point of such a horizontal well may be, for example, in a specially excavated target mine or in a basement room or he may also, i. as the starting point, are located at the surface of the earth, so that the drill head is reversed after a certain Bohr progress in an obliquely upward direction to let the drill head to exit again on the earth's surface.
  • an expander such as a conical expander
  • It can be provided to attach to the expansion device a newly retracted line to collect these simultaneously with the expansion of the pilot hole in the soil.
  • Horizontal drilling rigs are also used to replace trenchless trenchings buried underground.
  • the drill string is pushed by the drill carriage along the old line (and in particular by an old pipe) and after reaching a destination point, which may for example lie in a maintenance shaft of the sewer, the front end of the drill string connected to a widening device the old line is cut or ruptured during the retraction of the drill pipe, the parts of the destroyed old pipe are displaced radially into the surrounding soil.
  • a new pipe can be pulled into the old pipe.
  • the new pipe can have an outer diameter which corresponds to or even exceeds the outer diameter of the old pipe.
  • Horizontal drilling devices regularly have a linear drive, with which the drill string is driven in the ground and withdrawn; Furthermore, a rotary drive is provided regularly, with which the drill pipe (and thus the associated drilling or expander) can be set in rotation. Through the rotation of the drill head or the expander the propulsion in the soil can be improved.
  • a rotation of the drill head is required in order to be able to control it in the desired drilling direction.
  • the drill heads of such horizontal drilling devices have an asymmetrically shaped (eg bevelled) drill head front which results in lateral deflection of the drill head during movement through the soil. If the drill head is driven in rotation simultaneously with the driving in the ground, the asymmetrical design of the drill head has no influence on the straight bore course, because the lateral deflection compensates in the middle of a turn.
  • Horizontal wellhead drilling rigs are often only suitable for use in out-of-town areas as they must be positioned at a considerable distance from the area because of the tapping path required to achieve the desired depth of drilling in which the bore or the new pipeline is to be introduced into the soil or in which an existing old pipeline is to be replaced. Frequently, space is not available in built-up urban areas.
  • Another disadvantage of such Horizontalbohrvoriquesen is that these - regularly trained as a self-propelled Bohrlafette - horizontal drilling produce considerable land damage that must be eliminated again with a corresponding financial outlay.
  • a horizontal boring machine which is designed for use in small excavation pits with a rectangular cross section of about 70 cm x 40 cm and a depth of about 1 m to 1.5 m.
  • This horizontal drilling device comprises a frame whose dimensions correspond approximately to the cross-sectional dimensions of the excavation and which is lowered into the excavation. A part of the frame protrudes beyond the upper edge of the excavation.
  • a combined linear / rotary drive provided over a screwed from individual rod sections together drill pipe is driven into the soil.
  • the linear / rotary drive comprises a rotary drive which can be displaced in the horizontal direction within the frame by means of the linear actuator consisting of two hydraulic cylinders.
  • the last rod assembly is fixed non-positively in the rotary drive, for which the rotary drive has jaws.
  • the rod sections which are gradually screwed to the rear end of the already drilled drill string, are fed to the linear / rotary drive upper a linkage, which this from a rod magazine, in the upper, over the edge of the pit extending portion of the frame is arranged, transported to the linear / rotary drive.
  • the linkage comprises a changer motor whose motor shaft is provided with a threaded pin.
  • the threaded pin is screwed into the rear end of a linkage, which is intended for transport to the linear / rotary drive.
  • a disadvantage of the DE 196 33 934 A1 known Horizontalbohrvoriques is that due to the coaxial alignment of the changer motor, the new rod assembly and the drill string only relatively short (compared to the length of the frame) short rod sections can be used. However, the shorter the individual rod sections, the more frequently new rod sections have to be attached to the drill pipe in order to introduce the hole of the desired length into the ground. The preparation or release of a rod section is associated with a considerable amount of time.
  • the device has a rotary drive, which is not a has shown hollow shaft which is adapted to receive a pipe section, the front end can be screwed to the last linkage portion of the already located in the ground part of a linkage. To make this possible, is located on a carriage a clamping device for holding the linkage section. The power transmission between the hollow shaft and the linkage section is done upper form or frictional engagement.
  • the invention was the object of an improved method for operating a horizontal drilling and a specify improved horizontal drilling device.
  • a method for operating a horizontal drilling device which allows the use of as long as possible rod sections and a horizontal drilling device, which is suitable inter alia for carrying out this method should be specified.
  • the invention is based on the idea to provide as long as possible rod sections for the drill string in order to limit the time required for a rod change (ie, the attachment or release of a rod section to / from the drill string) to a minimum.
  • a rod change ie, the attachment or release of a rod section to / from the drill string
  • the rod sections are held during the linkage change of the removable motor. Since this changeover motor is positioned in a coaxial position behind the linkage, the maximum possible length of the rod sections is shortened at least by the length of the changeover motor.
  • the present invention is therefore based on a changer motor, as in the drilling device of DE 196 33 934 A1 is present to dispense, the linkage change the rod sections by means of the rotary drive (over which during operation of the drilling device, the drill pipe is then driven to rotate) perform. Since according to the invention also resorted to a rotary drive, which does not attack at the front or rear end of the rod sections, but this encompasses (so that it engages the mantle of the respective rod section), a design-related loss of length for the rod sections is avoided. These can thus be formed as long as possible.
  • the linkage boom provided for the linkage change is fixed in a form-fitting manner within the passage opening of the rotary drive.
  • a positive fixation of the rod sections has opposite to the DE 196 33 934 A1 known non-positive fixation on the advantage that the risk of slippage of the drill string is avoided at high loads and also the design effort that is required by the use of hydraulic cylinders to form a clamping device can be avoided.
  • a corresponding horizontal drilling device which is particularly suitable for operation according to a method of the invention, has a linear drive, a movable by means of the linear drive rotary drive and a drill pipe, wherein the rotary drive forms a through hole into which the drill string is pluggable.
  • the rotary drive within the passage opening on force transmission means for the positive transmission of pressure and / or tensile forces and / or torque on the drill string on.
  • the force transmission means are formed so that the drill string in a first angular position (the power transmission means relative to the drill string) can be plugged into or removed from the rotary drive, while in a second angular position a locking of Linkage is given, can be transmitted in accordance with the invention pressure and / or tensile forces and / or torque.
  • a locking of the linkage within the rotary drive is thus achieved via a relative rotation of the rod assembly relative to the power transmission means of the rotary drive.
  • a locking of the drill string in the rotary drive by a relative rotation can preferably be achieved in that the force transmission means comprise a power transmission ring which forms an opening through which the drill string can be inserted through.
  • the drill pipe in at least one first section to a cross section of the opening as far as corresponding first cross section, that the linkage in only the first angular position through the opening of the power transmission ring is pluggable.
  • the drill pipe has in at least one second section, which is formed as a partial section of the first section, has a second cross section, which differs from the first cross section, and which is configured so that the linkage can only be rotated into the second angular position when the second section is within the second angular position Opening of the power transmission ring is located.
  • the power transmission ring is interchangeable arranged in the rotary drive.
  • the cost of maintenance of the horizontal boring device according to the invention is kept low, since the power transmission ring, which is subject to a relatively large wear by the locking contact with the drill string, can be replaced without having to replace the entire rotary drive.
  • the drill string has a circular base cross-section, wherein this circular base cross-section in the first section is flattened at least on one side (and preferably on two sides with opposite parallel flats). Further preferably, the drill string may then have in the second portion at least one (preferably two) arcuate groove (s) which terminates in the lateral flattening (s).
  • the drill string is designed as a drill string of a plurality of interconnected rod sections, wherein each rod section has at least two first sections and at least two second sections. This can ensure that the rotary drive or the power transmission means of the rotary drive can engage two (spaced apart in the longitudinal direction of the rod assembly) positions of each rod section.
  • each rod section for the rod change at a first position and for drilling the drill string at a second position is fixed. This makes it possible to design the rod assembly longer than the maximum stroke of the linear drive, which generally always has to be significantly shorter than the length of the excavation pit (in the direction of the drilling axis) for design reasons.
  • a first and a second section are in the region of the two ends of each rod section, between which at least a third section is arranged, which have a lower bending stiffness than the two first sections.
  • This third section can be adapted to the overall bending stiffness of the individual rod section and thus of the entire drill string.
  • the rotary drive of the horizontal drilling device preferably has a hollow gear with a bevel gear driven by a motor, wherein the bevel gear meshes with a toothed ring, which in turn is rotatably connected to the power transmission means.
  • This configuration makes it possible to arrange the motor of the rotary drive in the vertical direction (i.e., perpendicular to the drilling axis) within the excavation, whereby the rotary drive as a whole can be kept as short as possible (in the direction of the drilling axis).
  • the smallest possible stroke for the rotary drive moving linear drive can be realized in tight spaces.
  • the linear drive of the horizontal drilling device according to the invention is preferably in the form of one or more drive cylinders (preferably operated hydraulically or pneumatically).
  • the rotary drive can then be connected to the linear drive by being connected to the cylinder tube (s) of the drive cylinder (s).
  • the Fig. 1 shows in an isometric view of a horizontal drilling device 1 according to the invention when introducing a pilot hole in the ground.
  • the horizontal drilling device comprises a cylindrical housing 2, which is partially closed by a cylindrical jacket 3. Functionally, the horizontal boring device 1 or the housing 2 of the horizontal boring device 1 is subdivided into two sections, namely a lower section called a "pit section", which is located inside a excavation pit 4 specially excavated for receiving the horizontal boring device 1.
  • the housing 2 In the pit section of the horizontal drilling device 1, the housing 2 is substantially completely closed by the jacket 3. This prevents soil from falling off the wall of the excavation 4 from falling into the cavity formed by the housing 2, where there are further functional elements the horizontal drilling device 1 and in particular a combined linear / rotary drive 5 is located. Otherwise, soil falling into the cavity could contaminate these functional elements, which could impair the function of the horizontal drilling apparatus 1.
  • the housing 2 is partially open in order to give an operator access to a linkage pin 6 extending into this area.
  • the horizontal boring device 1 is positioned "suspended" within the excavation 4, i. this is not supported on the bottom of the excavation 4, but rather on a support device with a total of three support legs 7, which are attached to the longitudinal members 8 of the housing 2 in the region of the surface portion of the horizontal drilling device 1.
  • Each of the support legs 7 can be attached to the respective side member 8 at a total of five different positions.
  • a height adjustment of the suspended in the excavation 4 horizontal drilling 1 done. This height adjustment is important to e.g. to position the located within the pit section linear / rotary drive 5 on the right for the introduction of the pilot hole in the ground height.
  • Each of the support legs 7 further comprises a spindle support, which is connected via a rotary joint with the cross member 10 of the respective support leg 7.
  • the spindle support comprises a threaded rod 11 which has a support leg 12 at its foot end.
  • a handle 13 is provided, via which the threaded rod 11 can be rotated about its longitudinal axis, whereby a longitudinal displacement relative to the threaded rod surrounding the spindle housing 14 is achieved.
  • the spindle supports serve to align the horizontal drilling device 1 within the pit 4 exactly after a first height positioning has already been achieved by the attachment of the support legs 7 to the side rails 8 of the housing 2.
  • the excavation 4 - as well as the housing 2 of the horizontal drilling device 1 - has a cylindrical shape whose inner diameter also corresponds substantially to the outer diameter of the housing 2 of the horizontal drilling device.
  • the shell 3 of the horizontal drilling device 1 in the region of the pit section is thus more or less directly against the wall of the Excavation 4 on. Due to the extensive agreement of the inner diameter of the excavation 4 and the outer diameter of the housing 2, not only the size of the excavation pit 4 to be excavated can be kept to a minimum, but it can be achieved within the excavation 4 as large as possible and homogeneous support of the horizontal drilling 1. Due to the circular cross-section of the excavation 4 and the housing 2, the support is also independent of the respective rotational orientation (about the longitudinal axis of the horizontal drilling).
  • the excavation 4 was excavated by first with a crown drill (not shown), an annular groove with the required (outer) diameter in the surface seal (asphalt surface) was introduced, which removes dislodged disc-shaped asphalt cover and then the underlying soil by means of a Suction dredger (not shown) was sucked.
  • the suction dredger used for this purpose comprises a suction nozzle, which likewise has a circular cross section.
  • the excavation 4 is excavated slightly lower than necessary in order to allow a height adjustment of the suspended horizontal drilling device 1 within the excavation 4, without causing an accidental placement of the lower end of the horizontal drilling 1 on the pit floor.
  • the horizontal drilling 1 was lowered by means of a crane (not shown) in the pit 4 until the previously secured to the side rails 8 of the housing 2 support legs 7 have contact with the earth's surface. With the help of the crane, the horizontal drilling device 1 was then still rotationally aligned within the excavation by being rotated about its longitudinal axis until the arranged by the arranged within the pit portion of the horizontal drilling 1 linear / rotary drive drilling axis has in the desired starting direction for the pilot hole , On the spindle supports then a fine adjustment of the working height of the horizontal drilling device 1 and within limits of the inclination of the horizontal drilling device 1 with respect to the vertical could be achieved.
  • the horizontal boring device 1 Since the wall of the excavation 4 - in particular when it was excavated by means of a suction dredger - is not uniformly cylindrical, the horizontal boring device 1 according to the invention has in the region of the excavation section a total of four support elements 15 distributed uniformly over the circumference. These support elements 15 comprise support plates 16, which in a retracted position in each case form a section of the cylindrical jacket 3 of the horizontal drilling device. The support plates 16 can each be deflected by means of a hydraulic cylinder 17 in the radial direction to the outside to make a direct contact of the horizontal drilling device 1 with the wall of the excavation 4 in order to safely support these within the excavation 4.
  • Each of the support plates 16 is connected via a first pivot 18 to a first end of a Auslenkhebels 19, which in turn is rotatably supported by a second pivot joint 21 on the housing 2 of the horizontal drilling device 1.
  • a second end of the Auslenkhebels 19 is connected to the head of a piston rod 20 of the hydraulic cylinder 17.
  • a extension and retraction of the hydraulic cylinder 17 thus causes a partial rotation of the Auslenkhebels 19 about the pivot 21, whereby the respective support plate 16 can be deflected radially or withdrawn.
  • End stops 22 prevent the support plate 16 when retracting the hydraulic cylinder 17 penetrates into the interior defined by the shell of the housing.
  • the Fig. 2 shows one of the Fig. 1 corresponding representation of the entire horizontal drilling device 1, but in which a part of the shell 3 is removed in the pit section to make visible the functional elements arranged therein.
  • Fig. 3 to 5 show various views of this portion of the horizontal drilling device 1 in enlarged views. It can be seen that the combined linear / rotary drive 5 is arranged at the lower end of the horizontal drilling device 1 within the housing 2. This serves to propel a composite of individual rod sections 23 drill pipe 24 rotating in the soil.
  • the Fig. 6 shows a partial section through the linear / rotary drive 5 in an isolated from the other elements of the horizontal drilling device 1 representation.
  • the linear drive is formed by two hydraulic cylinders 25.
  • the piston rods 26 of the two hydraulic cylinders 25 pass through the respective cylinder tube 27 completely and are connected at their two ends to the housing 2 of the horizontal drilling device 1.
  • the piston rods 26 each have a centrally disposed piston (not shown), which divides the respectively formed between the cylinder tube 27 and the piston rod 26 annular space into two working chambers, which can be supplied via a hydraulic line 66 with the hydraulic oil.
  • a movement of the respective cylinder tube 27 on the piston rod 26 in one or the other direction is achieved.
  • the movement of the two hydraulic cylinders 25 of the linear drive is synchronized.
  • a rotary drive is arranged between the two cylinder tubes 27 of the linear drive forming hydraulic cylinder 25 and secured thereto.
  • the rotary drive comprises a flange-mounted on a hollow gear 28 motor 29 (in particular a hydraulic or an electric motor).
  • a drive shaft 30 of the motor 29 is connected to a bevel gear 31, which in turn meshes with a toothed ring 32, which in turn is connected via screw 33 with a drive sleeve 34.
  • the drive sleeve 34 is rotatably supported by two roller bearings 35 within a housing 36 of the hollow gear 28. A rotation of the drive shaft 30 of the motor 29 thus causes a rotation of the drive sleeve 34 about its longitudinal axis.
  • This longitudinal axis substantially corresponds to the longitudinal axis of the drill pipe 24 held therein and consequently also to the drilling axis, ie the starting direction of a pilot bore to be introduced or the longitudinal axis of a bore or an old pipe extending in the wall of the excavation 4.
  • a drive ring 37 For transmitting the rotational movement of the drive sleeve 34 and the longitudinal movement generated by the hydraulic cylinders 25 of the linear drive on the drill pipe 34 held in the drill pipe 24 is a drive ring 37 which - fixed in an operating position of the drill string 24 within the driver ring 37 - the drill string 24 positively.
  • the driving ring 37 is mounted in a form-fitting manner within the drive sleeve 34 and can be exchanged in a simple manner by first removes a snap ring 63 from a corresponding groove in the inside of the drive sleeve 34 and then a spacer ring 64 is pulled out of the drive sleeve. The driver ring 37 can then be easily pulled out of the drive sleeve 34.
  • the Fig. 9a and 9b 10a and 10b show, in two views in each case, the two operating positions of the drill pipe 24 within the driver ring 37 relevant to the operation of the horizontal drilling apparatus 1. These two operating positions differ by a 90 ° relative rotation of the driver ring 37 about its longitudinal axis relative to the drill pipe 24.
  • the drill pipe 24 is locked in the drive ring. This locking is achieved by the special shell shape of the rod sections 23 of the drill string 24 and a shape adapted thereto of the central opening of the driver ring 37.
  • Each rod assembly 23 of the drill string 24 has a cylindrical basic shape with a relatively small diameter central portion 38 and two relatively large diameter end portions 39a, 39b.

  • cams 42 are formed whose distance is greater than the narrow width (corresponding to the distance between the two straight edges of the through hole of the driving ring) of the through hole of the cam ring 37. These cams 42 strike in the in the Fig. 9a and 9b illustrated locking position at the edges of the driving ring 37 and thus prevent further rotation (clockwise).
  • the middle section 38 of each rod section 23 has a reduced outer diameter in order to achieve a (defined) bending stiffness in relation to the end sections 39a, 39b. This should enable the use of a controllable inclined drilling head. By reversing the drill head 43 in the ground, a sectionally arcuate bore profile is achieved. The drill string 24 must adapt to this arcuate bore profile, which leads to a corresponding bending stress.
  • the reduced diameter and thus relative to the end portions 39a, 39b relatively flexible middle section 38 of each rod section 23 serves to keep the rod assembly 23 altogether pliable, while at the same time the end portions 39a, 39b, which are particularly vulnerable to breakage, stiff perform.

  • the two free ends of the two piston rods 49 are connected to the housing 2 of the horizontal drilling device 1, so that by a corresponding pressurization of the hydraulic cylinder 48 with hydraulic oil, the cylinder tubes 47 can be moved on the stationary piston rods 49 and consequently the boom support 44 in the horizontal direction.
  • the receiving mandrel 45 of the boom receptacle 44 is pivotally mounted within the bridge 46 about a horizontal axis, wherein a pivoting between the two in the Fig. 7a, 7b on the one hand and 8a, 8b on the other hand shown end positions is possible.

After the first stroke of the linear drive is moved back so that the driving ring 37 engage in the locking grooves and lock the drill head 43. Then the linear drive is again moved forward by one working stroke, whereby the drill head 43 is completely bored. The rotary drive is then in the example in the Fig. 4 and 5 illustrated foremost position.
  • a provided in the region of the passage opening locking fork (not shown) is then shut down.
  • the fork width of the locking fork corresponds to the distance between the two parallel flats of the drill head 43 and the distance between the two locking grooves.
  • the drill bit 43 was aligned by means of the rotary drive so that the two flats of the end portion are aligned vertically, so that the locking fork can drive over the end portion (in a section in front of the locking grooves) of the drill head 43, whereby rotation of the drill head by means of a positive fixation 43 is temporarily prevented.
  • the operator has already used a first rod section 23 in the receiving carriage 52 and attached it to the receiving mandrel 45 by a method of the linkage pin 6. After a pivoting of the mandrel 45 and the attached thereon rod assembly 23 by 90 ° in its horizontal orientation, the rod assembly 23 is in a largely coaxial position to the already drilled bit 43.
  • the two hydraulic cylinders 48 of the rod holder 44 can then the front Threaded plug of the rod assembly 23 are moved up to the rear threaded bushing of the drill head 43.
  • the driving ring 37 is then released from the locking grooves of the drill head 43 and the linear / rotary drive 5 is moved back so far that this is located in a defined region of the front end portion 39 a of the first rod section 23.
  • the first rod assembly 23 is screwed to the drill head 43 fixed in the direction of rotation by the locking fork, the torque being transmitted via the parallel flats 40.
  • the driving ring 37 is not yet locked in the locking groove 41, the rod section can be displaced relative to the driving ring 37 during screwing in the longitudinal axial direction.
  • the longitudinal movement of the rod section 23 required for screwing the rod section 23 can be realized without a complex length compensation realized by the linear drive.
  • the position of the rotary drive during the screwing is chosen so that the locking grooves 41 of the front end portion 39 a after the complete screwing of the rod section 23 with the drill head 43 within the driving ring 43, so that it can directly engage in the locking grooves 41 by a 90 ° rotation directly, that is, without another method of the linear drive is required to fix the rod assembly 23 in the longitudinal direction.
  • the drill string is then drilled so far until the rotary drive has returned to its front end position.
  • the rotary drive is unlocked by a 90 ° rotation (in the opposite direction) of the driver ring and moved back by means of the hydraulic cylinder 25 of the linear drive until the driver ring 37 can engage in the locking grooves 41 of the rear end portion 39b of the first rod section 23; There, the driving ring 37 is locked again by a 90 ° rotation. Then the drill string, consisting of drill head 43 and first rod assembly 23 is driven by the use of the linear / rotary drive 5 by a further working stroke of the linear drive further into the soil.
  • the locking grooves 41 of the front end portion 39a of the first linkage 23 are below the locking fork, which can then be lowered to fix the drill string while the second linkage 23 is bolted to the existing drill string.
  • the second rod assembly 23 is moved up by means of the rod holder 44 to the rear end of the first rod assembly 23.
  • the rotational drive is released from the first linkage 23 and moved backwards so far that it can engage the parallel flats 40 in the front end section 39a of the second linkage section 23.
  • the second rod section 23 is then screwed to the first rod section 23, wherein after completing the screwing of the cam ring 37 is locked again in the locking grooves 41 of the front end portion 39 a of the second rod section and the drill string back to the Reaching the front end position (of the linear drive) is bored.
  • the linear / rotary drive 5 is then released by a 90 ° relative rotation of the driving ring 37 of the second rod section 23 and moved back to lock the second rod section 23 in the rear end portion 39b and the drill string to another working stroke in to drive the soil.
  • the locking fork always engages in the locking grooves 41 of the rod sections 23 in order to secure this or the drill string not only rotationally but also against longitudinal movement. As a result, it is possible to prevent the drill string from shifting unintentionally due to elastic re-deformations of the compressed soil and of the drill string compressed or stretched by the loads.
  • the preparation and Verbohren further rod sections 23 is then carried out in an identical manner.
  • pilot bore After the pilot bore has been completed, it may be provided to replace the drill head 43 by a widening device (not shown) to widen the bore during retraction of the drill string.
  • a neural tube (not shown) or other supply line (not shown) may be attached to the expander head, which is retracted into the bore simultaneously with the expander.
  • the driving ring 37 of the rotary drive is locked in the locking grooves 41 of the rear end portion 39 b of the last rod section 23.
  • the rotary drive is moved by a process of the hydraulic cylinder 25 of the linear drive to the rear.
  • the locking fork is then moved down and fixes the penultimate rod assembly 23 by this in the locking grooves 41 of the rear end portion 39 b of this rod section 23 engages.
  • the linear / rotary drive is then released by a 90 ° rotation of the driving ring of the rod section 23 and moved forward again until the driving ring 37 can engage in the locking grooves of the front end portion 39a of the last rod section 23.
  • the drill string 24 is pulled out of the ground so far that the locking fork can lock the penultimate rod section 23 in the front end portion 39a. Then the last rod section 23 can be unscrewed from the penultimate rod section 23 by a rotation of the drive sleeve 34 in the counterclockwise direction. Due to the particular shape of the rod section in the region of the end sections, a torque for releasing the threaded connection can be transmitted without the carrier ring 37 being fixed in the locking groove 41 also in the longitudinal axial direction. This allows the driving ring 37 slide when unscrewing the rod assembly 23 according to the thread pitch over the rod section, whereby a length compensation on the linear drive can be avoided.
  • the horizontal drilling device shown is particularly suitable for use in inner city areas and in particular for the creation of domestic connections in the supply area (in particular gas, water, electricity, glass fiber, etc.). Drill holes of up to 20 meters in length can be drilled and used to retract pipes or cables with an outside diameter of up to 63 mm.
