Description

The invention relates to a Erdbohrgerät, in particular a Horizontalspülbohrmaschine.

Earth drilling equipment, in particular horizontal drilling machines, are mainly used for the trenchless construction of supply lines for electricity, gas, water and telecommunications lines. Advantages of the Spülbohrverfahrens compared to the excavation of a trench are in a shorter time, an associated high line performance and the protection of the (soil) surface. Advantageously, obstacles (such as roads, waterways, walls or the like) can be "undermined" so that even with existing infrastructure subsequently and / or with AS POSSIBLE influence on the existing soil surface corresponding lines can be laid.

As part of a flushing hole, a so-called pilot hole (usually with a final diameter relative to a relatively small start diameter) using a controllable drill head, which is arranged on a comparatively flexible drill string, and a drilling fluid (usually a bentonite-water mixture) is driven forward , The start and end points are usually each in a starting pit or in a target pit. The drilling fluid serves to loosen the soil and / or rock surrounding the drill head, to displace it and / or to "flush it out" and to carry away the flushed out material and to stabilize the drilling channel. In a subsequent step, the drill hole of the pilot hole is widened to the desired diameter by means of a "scraper" (an enlarged drill head, also: "clearing head"). Optionally, several Räumschritte done until the drill channel is widened to the target diameter. In a final step, the tube is now drawn into the created and, if necessary, expanded bore.

In particular, when using Erdbohrgeräten, concrete (horizontal) Spülbohrmaschinen for house connections and road crossings in inner city areas, the space is often extremely cramped and the drilling distances short. In addition, narrow (passage) openings such as gates, court entrances, garden doors, but also sidewalk widths limiting factors for the use of a Horizontalspülbohrmaschine. Therefore, the size and maneuverability of the horizontal drilling machine used is a crucial factor for the performance of the machine and thus for the economy and the time required for the drill. In addition, short drilling distances require the provision of only a few boring bars. Therefore, improvements are needed to increase the compactness, maneuverability and flexibility of horizontal drilling machines.

The invention has for its object to provide an improved Horizontalspülbohrmaschine.

This object is achieved by a Erdbohrgerät with the features of claim 1. Advantageous and partly inventive embodiments and refinements of the invention are set forth in the dependent claims and the description below.

The earth boring device according to the invention is preferably a horizontal drilling machine. The auger has a landing gear and a superstructure carried by the landing gear. Furthermore, the auger has a drill mount (also referred to as a "drill ramp"), which - in particular in the intended drilling operation - is used to guide a drill string. The drill carriage is arranged on the superstructure, specifically supported by this. The uppercarriage is also pivotable relative to the chassis about a vertical axis (the horizontally oriented Erdbohrgerät along the vertical runs) rotating axis.

Particularly preferably, the superstructure is 360 ° and in particular endless pivotable.

More preferably, the Erdbohrgerät is a compact Erdbohrgerät (in particular a compact Horizontalspülbohrmaschine).

Preferably, the chassis is designed as a crawler chassis. The chassis in this case comprises in particular two track tracks (also referred to as "track chains") and correspondingly assigned drive, running and / or guide rollers. Preferably, the caterpillars are formed as plastic chains or have at least plastic or rubber chain pads on.

The pivotability of the superstructure relative to the chassis increases the flexibility and efficiency of the auger, which in turn can increase the cost of a construction project comprising the well bore. For example, the pivotability of horizontal wells by home gardens is advantageous because it is often (eg. For house connections) drilled from the property in the direction of a street-side pit. A most required screwing ("maneuvering") of the entire Erdbohrgeräts (especially the Horizontal Spülbohrmaschine) in the final working position on the property with the most associated damage to the property surface (eg., Lawns or the like) by the (crawler) chassis can thus be omitted. Damage to the property surface due to possible maneuvering can thus be advantageously prevented. But even with the reverse direction of drilling - especially from the road or the sidewalk in the direction of land - the increased flexibility due to the pivoting advantage.

The use of a crawler track also allows a comparatively high stability and in particular with respect to a wheel base a low ground pressure, so that even relatively sensitive surfaces (such as lawns) can be spared.

In an expedient embodiment, the auger comprises a slewing mechanism, by means of which the superstructure is coupled to the chassis. For example, the swing mechanism is formed by a turntable and a kingpin, which serves as a rotary connecting element between the superstructure and the chassis. Optionally, the turntable is part of a (hydraulic or electric motor operated) swivel gear.

In a further advantageous embodiment, which is also an independent of the above-described pivotable coupling of superstructure and chassis invention, the drill carriage is arranged on the outside of the superstructure. The term "outside" here and hereinafter means in particular that the drill mount to the rotation axis described above (and in particular in a transverse to a longitudinal direction of the drill mount direction) offset and / or (should no rotation axis be present) from a central position or center axis of the upper carriage away (especially "off-centered") is arranged offset. Preferably, the externally arranged drill carriage forms on a (viewed from the central axis) left or right side of the upper carriage of which is arranged at the outermost assembly. Further preferably, the drill carriage is mounted on a plane which is arranged in particular above a plane described by a chassis upper edge. In this case, for example, the drill mount is arranged in the area above a lane (for example one of the track chains). As a result, a particularly narrow design of Erdbohrgeräts is achieved, which in turn allows use behind narrow passages. In addition, the drill carriage in this embodiment but also particularly easy for manual operation, in particular for inserting, changing and / or removal of drill rods, accessible. In the context of the independent invention here eliminates the above-described pivotal coupling of the superstructure on the chassis, so that the superstructure is particularly rigidly connected to the chassis. Preferably, however, the outside arrangement of the drill carriage and the pivoting of the superstructure are combined with respect to the chassis.

In order to guide the drill string (usually formed from a variable number of drill rods set against each other), the drill string preferably has a drill drive and a drilling carriage. In operation, these move the drill string along a drilling axis (i.e., in the drilling direction) and apply or transmit the required torques and feed forces for the bore. In this case, the drill carriage is set up to push the drill pipe (on which a drill head is mounted on the front end side) forward into the drill hole during normal operation and to retract it during the widening of the drill hole (by means of a reaming head coupled to the drill pipe). The transmission of the tensile and compressive forces on the drill string is preferably carried out by a "feed drive", in particular formed by a gear drive (comprising, for example, a rack, pinion and / or a chain) or a hydraulic cylinder.

To carry out a flushing hole, in particular a single boring bar is therefore preferably placed manually on the drilling carriage and connected via a spindle to the boring drive (and thus indirectly to the boring carriage). In the following, the drilling carriage and thus also the inserted boring bar are moved towards the front end of the boring carriage (viewed in the drilling direction). As soon as the boring bar has reached the front end of the boring carriage (in particular with its end area), the boring bar is separated from the spindle. The drill carriage is then moved back towards the rear end of the drill carriage, so that subsequently optionally a further drill rod inserted (in particular connected to the previous and moved forward) can be. This process is repeated until the drill pipe is completed and drilling is completed. Upon completion of the drilling operation, the drill pipe (formed by the individual boring bars) is moved by means of the drilling carriage towards the rear end of the machine and incrementally removed individual boring bars. After removing a boring bar, the boring carriage is again moved forward there coupled to the next boring bar of the drill string.

In a further expedient embodiment, the auger has a rod housing (also referred to as "rod magazine"), which is for holding the boring bars (in particular during the Drilling operation) is used. Preferably, the rod housing is arranged on the inside next to the externally positioned drill carriage, in particular approximately centrally on the superstructure. More preferably, the rod magazine is designed for manual operation. This is particularly advantageous for a compact earth drilling rig, since in this case also the drill rods to be used can be lifted and used comparatively easily and thus manually. In this case, the structure of the bar magazine is comparatively simple, since an automated supply of boring bars can be omitted on the drill carriage. The inside arrangement next to the drill mount allows in particular a nearly direct access to the bar magazine with short handling paths and preferably without obstacles that would have to be overcome with a drill rod in the hand. In particular, the rod magazine for storing a plurality of "stack of stacks" is arranged side by side, for example by means of dividers for forming each of a stack of stacks receiving subjects. Optionally, the bar magazine is set up for loose or "zig-zag" stacking of the drill rods.

The bar magazine described above expediently has a filling opening for the drill rods. The filling opening is preferably arranged in a (at least in drilling operation) upwardly facing region of the bar magazine. In particular, boring bars can be refilled through the filling opening even during an ongoing drilling operation. Optionally, the rod magazine also has a second opening ("removal opening") arranged near the bottom (in particular laterally), from which the boring bars can be removed during drilling operation. In the latter case, the rod magazine also has a separating device, which is used for piecewise output of the drill rods (for example, in the manner of a turnstile) and in particular prevented falling out several drill rods at once.

In a preferred embodiment, which is also an independent invention, which in turn is optionally independent in particular of the above-described pivotable coupling of superstructure and chassis and / or the outside arrangement of the drill carriage, which is the drill carriage (ie also the drilling carriage and the drill drive) in the direction of its longitudinal axis (in particular horizontally) between a plurality of drilling positions (also: "displacement positions") slidably mounted on the superstructure. For example, the drill carriage is displaceable between a plurality of discrete positions. Preferably, however, the drill carriage is continuously displaceable between freely selectable drilling positions. In this context, "drilling position" is understood here and below to mean, in particular, an arrangement of the (preferably entire) drill carriage along its displacement path, in particular with the drill carriage being disposed at this "ejection position" or "extension stroke" in the intended drilling operation. In an optional, independent embodiment, the above-described pivotable coupling of the superstructure with the chassis and / or the outside arrangement of the drill carriage omitted. Preferably, however, the longitudinal displaceability of the drill carriage is combined with at least one of the embodiments described above (i.e., pivotability or outboard arrangement). Due to the longitudinal displaceability between the several drilling positions a particularly high flexibility of the auger is advantageously achieved in terms of its dimensions (in particular its longitudinal extent) in the working state at the same time as small a length for transport.

In a preferred embodiment, the drill carriage is mounted for longitudinal displacement on a rail guide, in particular by means of a sliding carriage. Preferably, the rail guide is assigned a displacement unit, in particular a hydraulic cylinder or another type of "linear drive" (for example a belt drive, gear drive or the like) for displacing the drill carriage in the longitudinal direction.

Particularly preferably, the Erdbohrgerät, in particular in the case described above, the longitudinally displaceable Bohrlafette, a transport length less than three meters. As a result, the Erdbohrgerät is particularly compact and thus used on a variety of construction sites with particular low workspace.

In a further expedient embodiment, the drill mount is articulated in particular by means of a tilting device about a tilting axis transverse to the longitudinal axis about an insertion angle tiltable on the uppercarriage. The term "piercing angle" is to be understood in particular as the angle at which the drill pipe (in particular with respect to the horizontal, but at least with respect to the surface of the substrate directly surrounding the earth boring device) is pierced into the substrate. Since the drill carriage is placed on the ground with a front end in the intended drilling operation (hereinafter referred to as "drilling position"), the piercing angle thus corresponds to the tilt angle of the drill mount relative to the chassis. Preferably, the tilting axis is stationary relative to the superstructure. In particular, for this purpose, the rail guide on which the drill carriage is slidably mounted by means of the sliding carriage, hinged to this tilting axis adjustable on the superstructure and can thus be employed together with the drill carriage to the piercing angle relative to the superstructure. The tilting device points preferably a (in particular hydraulically operated or, for example, formed by a spindle motor) tilt cylinder, which is adapted for transmitting power to the drill carriage, in particular on the rail guide for tilting. By the tilting device is possible (especially in "extended" drill mount) a flat piercing of the drill string in the drill hole at the installation, so that only a small bending of the drill string over the drilling distance is required. In particular, in combination with the displaceably mounted drill mount a variation of the insertion angle is possible. By not or only slightly "extended" the drill mount, namely to settle the front end of the drill mount this must be tilted accordingly "steeper".

Conveniently, in the intended drilling position (at the site of the Erdbohrgeräts) the drill carriage is extended and tilted in particular by means of the sliding carriage, so that the front end of the drill carriage rests on the ground, preferably supported. As a result, the auger is advantageously stabilized for the drilling operation.

In an advantageous embodiment, the rod magazine - to this always as close to the drill mount to arrange - is also mounted in a tilt angle and adjustable in the longitudinal direction of the superstructure. Basically, it is possible that the rod magazine by means of a separately associated tilting device and a separate displacement device to store adjustable. Particularly preferred is the rod magazine but for concurrent adjustment - preferably for displacement and tilting - coupled to the drill mount, for example. Held on this.

In a further expedient embodiment, the drill carriage can be lowered in the vertical direction (that is to say essentially vertically) next to the running gear. This embodiment also constitutes an independent invention independent of the pivotability of the superstructure (and optionally of the longitudinal displaceability). In particular, the earth boring device for lowering has a corresponding device, which is preferably designed to lower the drilling carriage by the height of the undercarriage. For example, this device is designed as a folding device such that the drill mount can be folded down to the side about a folding axis extending parallel to its longitudinal axis. For example, the folding device for this purpose comprises a correspondingly designed hinge and a (optionally hydraulically or electromotively operated) lever arrangement. Alternatively, the device as (hydraulically or electric motor operated) lifting and lowering device, for example. Formed according to a kind of "elevator", so that the drill carriage can be lowered or raised with a "purely translational" height adjustment.

In both cases described above, the device for lowering the drill mount and thus the lowering but expediently automatically locked when the superstructure is pivoted out of its zero position (in the direction of travel and longitudinal direction of the drill mount) out against the chassis. Optionally, the lowering (in particular control technology) is released only on the condition that the superstructure is secured against pivoting from the zero position. Due to the sinkability of the drill mount, particularly flat puncturing angles are made possible and the compactness and thus also the flexibility of the auger can be further increased.

In a further advantageous embodiment, the chassis is adjustable in its track width. For this purpose, the chassis preferably comprises a drive (for example a hydraulic cylinder or an electromotive drive) designated as a "spreader cylinder", which is arranged between the two lanes, in particular between the two parallel track chains. For example, the two crawler belts, in particular those carrying and driving running, guiding or driving rollers, are coupled to one another by means of telescopic axles. Optionally, two carriers, on which the respective crawler associated run, -Führungs- and / or drive rollers are suspended, coupled by means of telescoping cross member. Due to the adjustability of the track width advantageously on the one hand a comparatively high stability of the machine is ensured at the installation and on the other hand allows the machine to handle still narrow passages. During transport and travel of the machine, the landing gear is preferably in the retracted (i.e., narrow) position to maintain the compactness and flexibility of the machine. At the installation site, the landing gear can advantageously be ascended as required (in particular hydraulically) in order to increase the stability during the drilling process.

In a preferred embodiment, the Erdbohrgerät on a rinsing fluid tank, which is arranged on the chassis or on the superstructure. The rinsing liquid tank is set up to receive a sufficient amount of rinsing liquid, preferably for a self-sufficient drilling operation. For this purpose, the rinsing liquid tank preferably has a capacity of about 100-400 liters, in particular of up to about 200 liters. This amount of rinsing liquid tank is regularly sufficient for drilling to be carried out with the above-described, particularly compact earth drilling rig. A self-service of a Construction site through the Erdbohrgerät is thereby advantageously possible. A separate system for the continuous supply of the rinsing liquid and in particular the associated line outlay can thus advantageously be dispensed with. In particular, such systems are often arranged on comparatively large vehicles, which may not be able to drive on the access roads to the corresponding construction site. The rinsing liquid tank preferably has a filling opening for filling with (optionally premixed) rinsing liquid. An external mixture allows a saving of space on the Erdbohrgerät.

In the intended drilling operation, the filling opening of the rinsing liquid tank is preferably closed. In particular, it is provided to refill the rinsing liquid tank for each drill section separately with the respectively appropriate amount of rinsing liquid, so that a permanent connection between the external system (in particular the mixing device) and the earth boring device, for example in the form of a liquid hose is not necessary. As a result, installation times of the mixing device can advantageously be shifted, the set-up time of the auger can be minimized, and in this way the performance of the auger can be increased.

Preferably, the Erdbohrgerät also has a drill pump for acting on the rinsing liquid with a Bohrdruckwert. In particular, the drilling pressure value is dimensioned in such a way as to convey the rinsing liquid over the corresponding distance through the drill pipe to the drilling or clearing head and to allow a discharge speed sufficient for the drilling task when emerging from the nozzles arranged on the drilling or reaming head. This drill pump is expediently connected downstream of the rinsing fluid tank described above, optionally with the interposition of a delivery pump, which serves to supply the rinsing fluid to the drilling pump.

In an expedient embodiment, the Erdbohrgerät comprises a control panel, in particular for the operation of the drill carriage, d. H. in particular the drilling carriage and the drill drive, used in drilling operation. The control panel is designed in particular as a standing desk (for operation with upright posture) and preferably supported between a transport position and a working position pivotally relative to the uppercarriage and / or the chassis. Preferably, the control panel is articulated in a drilling in the front direction of the field drilling device. This allows the control panel to be flexibly adjusted to a position from which an operator of the auger has a good overview of the drilling process. In addition, advantageously space and installation costs for an operator seat omitted. Optionally, the control panel is also set up to operate the entire earth boring device, for example for driving operation, pivoting of the upper carriage, shifting and tilting of the drill carriage (and possibly of the rod magazine). Further optionally, the earth boring device comprises (in addition or as an alternative), in particular for the travel operation, the shifting and / or the tilting of the drill mount, a second operating stand, in particular fixed to the upper carriage.

In a further expedient embodiment, the Erdbohrgerät comprises a particular central drive motor for generating an operating power for a drill drive, a traction drive, the slewing gear, the displacement unit and / or the drilling pump. For example. it is in this drive motor to an internal combustion engine, an electric motor or a hybrid motor which drives in particular a hydraulic pump, by means of which further, in this case, preferably hydraulically operated bottom drives such as the drill drive, the traction drive, the swing mechanism, the drilling pump, the Displacement unit (concretely the hydraulic cylinder) for the drill carriage, the spreader cylinder, a tilting cylinder for tilting the drill carriage and the like are subjected to the required hydraulic pressure. Alternatively, the earth boring device for each assembly to be moved in particular includes an associated electric motor drive, which is optionally fed via an accumulator of Erdbohrgeräts or via a power connector for an external power supply. Furthermore, the earth boring device preferably comprises a motor housing associated with and surrounding the motor housing, which in particular covers a cover cover as large as possible in order to allow easy access to the drive motor and the possibly existing and preferably also arranged in the motor housing hydraulic pump in case of maintenance.

Preferably, the auger has a (support) frame which forms at least a part of the superstructure and a supporting basic structure for holding the assemblies, d. H. in particular, the drill carriage, the rod magazine, the drive motor and the motor housing, possibly the rinsing fluid tank and the like. The optional motor housing and / or the rinsing liquid tank are arranged on the opposite side of the drill carriage (left or right side) of the upper carriage. The rinsing fluid tank can be positioned in front of or behind or also positioned on the motor housing in the drilling direction.

To increase the stability of the auger in drilling operation, this has expediently (in particular hydraulically actuated) supports (support cylinders), which are preferably arranged in the drilling direction at the rear end of the frame of the superstructure. The supports are, for example, by means of the second (rear) control station or the control panel for moving to the working position controllable.

In 1 is an earth boring device, hereinafter referred to as "Horizontalspülbohrmaschine 1" shown. The horizontal rinsing machine 1 includes a chassis 2 and a superstructure carried by this 3 , The horizontal rinsing machine 1 also has a drill carriage 4 on, on the uppercarriage 3 is arranged. The drill carriage 4 has in unshown form on a drilling carriage, by means of which in the intended drilling operation, a part of a drill string forming drill rod 6 in a longitudinal direction 8th the drill carriage 4 (ie along its longitudinal axis) can be moved. For this purpose, the drilling carriage is power transmission-coupled with a gear drive, also not shown. In addition, the drill mount includes 4 Also, a drill drive, not shown, which serves to the drill rod 6 to rotate about its longitudinal axis and to transmit a drilling torque to this. At a front end seen in the direction of drilling 10 indicates the drill carriage 4 also a clamping device 12 on which serves, an inserted boring bar 6 to hold it against rotation with the drill drive and with another drill rod 6 couple (or cancel a coupling), specifically around individual drill rods 6 screw together.

The chassis 2 is designed as a crawler chassis and has two, each forming a lane caterpillars 14 on. Due to the longitudinal alignment of the two caterpillars 14 is a direction of travel 16 specified.

At the superstructure 3 is a motor housing 18 arranged, which surrounds a drive motor which serves to drive a hydraulic pump (in each case not shown in detail). Furthermore, there are two support cylinders 20 at a rear end 22 of the superstructure 3 arranged, which can be discontinued during drilling on the ground and for supporting the Horizontalspülbohrmaschine 1 serve. The support cylinders 20 are coupled fluid transmission technology with the above-mentioned hydraulic pump.

To the Horizontalspülbohrmaschine 1 To be able to adapt as flexibly as possible to the respective place of use is the superstructure 3 about a swing mechanism 24 with the chassis 2 coupled. The swing mechanism 24 is in the present embodiment by a turntable 26 and a (not shown) king pin formed. The swing mechanism 24 allows pivoting (also: rotation) of the upper carriage 3 around a rotation axis 28 that coincides with the kingpin, opposite the landing gear 2 (please refer 4 and 5 ).

To the Horizontalspülbohrmaschine 1 at least for transport with a shortest possible length of less than three meters, is the drill rig 4 by means of a sliding carriage 30 along a rail guide 32 between several, freely selectable drilling positions along its longitudinal direction 8th displaceable. A coupled to the hydraulic pump displacement unit (concretely a hydraulic motor with a rack and pinion gear), which is to move the drill carriage 4 required force on the sliding carriage 30 is not shown in detail.

Furthermore, the Horizontalspülbohrmaschine includes 1 a tilting device with a hinge 34 on a daytime frame 36 of the superstructure 3 is arranged. On the support frame 36 are also all assemblies of the superstructure 3 held (ie, for example, the hydraulic pump, the drive motor, the drill carriage 4 , the drive housing 18 Etc.). The hinge 34 forms a tilting axis, around which the drill carriage 4 , specifically the drill rig 4 meeting sliding carriage 30 around an insertion angle 38 (S. 9 ) can be tilted. To tilt the Sliding carriage 30 The tilting device also has a tilting cylinder (not shown), which is also coupled to the hydraulic pump. Depending on the drilling position, ie depending on the stroke length of the drill carriage 4 opposite the chassis 2 can therefore by means of the tilting device and the displacement of the insertion angle 38 be set steep or flat. In the intended drilling position (s. 9 ) is the drill carriage 4 with her front end 10 on the ground and is thus (to stabilize the Horizontalspülbohrmaschine 1 ) supported on the ground.

To provide additional and required drilling operations to advance the well required drill rods 6 has the Horizontalspülbohrmaschine 1 also as a "bar magazine 40 "Designated rod housing on. This bar magazine 40 is with the drill carriage 4 coupled, so the bar magazine 40 with every movement of the drill carriage 4 (ie when moving by means of the sliding carriage 30 or when tilted about the tilt axis) is moved with. Thus, the bar magazine 40 always equidistant from the drill carriage 4 arranged.

To enable a self-sufficient drilling operation, includes the Horizontalspülbohrmaschine 1 a rinsing fluid tank 42 in the area of the rear end 22 of the superstructure 3 arranged, concretely on the support frame 36 is attached. The rinsing fluid tank 42 It is designed to hold flushing fluid sufficient to carry out relatively small drilling operations, such as laying pipes on an already built property. The rinsing fluid tank 42 associated with a drilling pump, not shown, which serves to pressurize the drilling fluid with a Bohrdruckwert, which is sufficient to promote the drilling fluid through the drill pipe through to the drill head and for local atomization under pressure into the surrounding soil.

As it is in the Horizontalspülbohrmaschine 1 is a compact machine that is set up for manual operation - ie for manual loading or unloading of the boring bars 6 into and out of the drill carriage 4 - is the drill carriage 4 on the outside of the superstructure 3 , Specifically to a seen in the drilling direction left side of the superstructure 3 staggered. This is the drill carriage 4 easily accessible for manual operation. The bar magazine 40 is the inside of the superstructure 3 offset next to the drill carriage 4 arranged. On the other, right side of the superstructure 3 are the drive housing 18 and the rinsing fluid tank 42 arranged.

For flexible operation of the Horizontalspülbohrmaschine 1 this includes a control panel 44 , which pivots on a front area of the motor housing 18 is arranged. Specifically, the control panel 44 - Which is designed as a standing desk - on the opposite side of the upper carriage 3 So over the drill 4 be pivoted away, allowing a particularly flexible choice of the workstation on the Horizontalspülbohrmaschine 1 , About the control panel 44 the drill drive and the drilling carriage are activated.

The chassis 2 also has a spreader cylinder, not shown, by means of which the track width - ie the distance between the two tracks 14 - can be adjusted. As a result, if necessary - for example, at the side swung-out position of the upper carriage 3 (see 4-6 ) - the stability of the Horizontalspülbohrmaschine 1 be further increased.

In another embodiment, not shown, the Horizontalspülbohrmaschine 1 also a folding device, by means of which the drill carriage 4 along its longitudinal extent laterally from the superstructure 3 folded down and thus can be lowered in the direction of the ground. This allows a particularly shallow puncture angle 38 be enabled.
