Besonders bevorzugt weist der Kabelpflug kein eigenes Fahrwerk auf oder ist mit keinem angrenzenden Fahrwerk verbunden.Particularly preferably, the cable plow does not have its own undercarriage or is not connected to any adjacent undercarriage.

Es kann vorgesehen sein, dass die Abstützung gegen den Untergrund mittels des horizontalen Schwerts und/oder des Steuerpiloten vorgesehen ist.It can be provided that the support against the ground is provided by means of the horizontal sword and/or the control pilot.

Die Vorteile der Erfindung liegen insbesondere darin, dass in einem einzigen Arbeitsschritt alle Leitungen, beispielsweise alle drei vorgesehenen Leitungen, parallel in den Untergrund bzw. Erdboden eingebracht werden können. Der Abstand der Leitungen ergibt sich hierbei aus der Anordnung der Verlegeeinheiten zueinander, er bleibt während des Einpflügens konstant. Somit ist ein konstanter Abstand der auf diese Weise verlegten Leitungen gewährleistet.The advantages of the invention are, in particular, that all lines, for example all three lines provided, can be laid in parallel in the subsoil or ground in a single work step. The distance between the lines results from the arrangement of the laying units in relation to one another and remains constant during ploughing. This ensures a constant distance between the lines laid in this way.

Ferner besteht ein wesentlicher Vorteil des erfindungsgemäßen Rohr- und/oder Kabelpflugsystems darin, dass kein Fahrgestell vor dem Kabelpflug angeordnet ist, welches im Bereich der zu verlegenden Leitungen dem Kabelpflug vorausfährt. Ein solches Fahrgestell würde Druck auf den Boden ausüben und diesen somit beschädigen. Die Bodenoberfläche bleibt somit während des gesamten Verlegeprozesses mit dem erfindungsgemäßen Rohr- und/oder Kabelpflugsystem unbeschädigt.Furthermore, a significant advantage of the pipe and/or cable plow system according to the invention is that no chassis is arranged in front of the cable plow that drives ahead of the cable plow in the area of the cables to be laid. Such a chassis would exert pressure on the ground and thus damage it. The floor surface thus remains undamaged during the entire laying process with the pipe and/or cable plow system according to the invention.

Das Weiteren liegt ein wesentlicher Vorteil der Erfindung darin, dass durch den Steuerpiloten eine unerwünschte Höhenveränderung des Kabelpflugs, beispielsweise ein Abkippen in den Untergrund mit der Folge immer größer werdenden Verlegetiefen, verhindert wird. Der Steuerpilot sorgt dafür, dass der Kabelpflug beim Einpflügen der Leitungen auf einem vorgesehenen, insbesondere konstanten Niveau verbleibt. Dadurch wird sichergestellt, dass die einzupflügenden Leitungen in vorgesehener, vorzugsweise konstanter Tiefe verlegt werden.Furthermore, a significant advantage of the invention is that the control pilot prevents an undesirable change in height of the cable plow, for example tipping into the ground with the consequence of ever increasing laying depths. The control pilot ensures that the cable plow remains at a specified, in particular constant, level when plowing in the lines. This ensures that the lines to be plowed in are laid at the intended, preferably constant, depth.

Die Zugfahrzeuge weisen ferner bevorzugt jeweils ein Abstützschild auf.The towing vehicles are, in particular, preferably all-terrain vehicles that have cable winch devices for pulling the cable plow. The towing vehicles also preferably each have a support plate.

Besonders bevorzugt ist der Steuerpilot schlittenartig oder kufenartig ausgebildet.The control pilot is particularly preferably designed in the manner of a sledge or runners.

Gemäß einer Weiterbildung der Erfindung ist vorgesehen, dass der Steuerpilot, insbesondere an seiner Unterseite, eine Abstützfläche gegen den Untergrund aufweist, wobei die Abstützfläche eine nach unten gerichtete Bewegung und/oder ein Nach-Unten-Kippen und/oder ein Nach-Vorne-Kippen des Kabelpflugs beim Ziehen des Kabelpflugs durch den Untergrund vermeidet.According to a further development of the invention, it is provided that the control pilot has a support surface against the ground, in particular on its underside, the support surface being able to move downwards and/or tilt downwards and/or tilt forwards of the cable plow when pulling the cable plow through the ground.

Bevorzugt liegt der Steuerpilot mit der Abstützfläche auf dem Boden eines Leitgrabens und/oder einer Startgrube auf, und/oder gleitet mit der Abstützfläche über den Boden eines Leitgrabens und/oder einer Startgrube.The control pilot preferably rests with the support surface on the bottom of a control trench and/or a launch pit, and/or slides with the support surface over the base of a control trench and/or a launch pit.

Gemäß einer Weiterbildung der Erfindung weist das Rohr- und/oder Kabelpflugsystem eine Auflageplatte auf, wobei die Auflageplatte am Steuerpiloten angeordnet ist, und wobei die Auflageplatte an ihrer Unterseite eine Auflagefläche aufweist, die zur Auflage auf der Bodenoberfläche, insbesondere seitlich einer Startgrube und/oder eines Leitgrabens vorgesehen ist.According to a further development of the invention, the pipe and/or cable plow system has a support plate, the support plate being arranged on the control pilot, and the support plate having a support surface on its underside which is intended for support on the ground surface, in particular on the side of a launch pit and/or a guide trench is provided.

Vorzugsweist ist die Auflageplatte an einer Verbindungsfläche des Steuerpiloten angebracht, wobei die Verbindungsfläche insbesondere im vorderen Bereich der Oberseite des Steuerpiloten vorgesehen ist.The support plate is preferably attached to a connecting surface of the control pilot, the connecting surface being provided in particular in the front region of the upper side of the control pilot.

Bevorzugt ist die Auflageplatte dazu vorgesehen und/oder ausgebildet, ein seitliches Wegkippen des Steuerpiloten und/oder des Kabelpflugs bei ungleichmäßigem Ziehen durch das oder die Zugfahrzeuge zu vermeiden.

Benachbarte Verlegeeinheiten können auch in einer vorgesehenen Fahrtrichtung zumindest abschnittsweise hintereinander und/oder entlang der vorgesehenen Fahrtrichtung versetzt zueinander vorgesehen sein.The laying units can be provided next to one another in an intended direction of travel and/or at the same height in an intended direction of travel. Neighboring laying units can also be provided at least in sections one behind the other in an intended direction of travel and/or offset to one another along the intended direction of travel.

Bevorzugt sind drei Verlegeeinheiten zum Einbringen von drei Leitungen in den Untergrund vorgesehen, wobei die Verlegeeinheiten nebeneinander angeordnet sind, wobei die mittlere Verlegeeinheit in der vorgesehenen Fahrtrichtung zumindest abschnittsweise vor den beiden äußeren Verlegeeinheiten angeordnet ist.Three laying units are preferably provided for laying three lines in the ground, the laying units being arranged next to one another, the middle laying unit being arranged at least in sections in front of the two outer laying units in the intended direction of travel.

Besonders bevorzugt ist der Steuerpilot in der vorgesehenen Fahrtrichtung vor der mittleren Verlegeeinheit angeordnet.The control pilot is particularly preferably arranged in front of the central laying unit in the intended direction of travel.

Gemäß einer Ausführungsvariante der Erfindung ist der Steuerpilot mittels wenigstens einer Führung, vorzugweise einer Parallelführung, mit der mittleren Verlegeeinheit verbunden, wobei die wenigstens eine Führung vorzugsweise gelenkig an dem Steuerpiloten und/oder der mittleren Verlegeeinheit angebracht ist.According to one embodiment of the invention, the control pilot is connected to the middle laying unit by means of at least one guide, preferably a parallel guide, the at least one guide preferably being articulated on the control pilot and/or the middle laying unit.

Gemäß einer Weiterbildung weist der Steuerpilot einen Tiefenbegrenzer auf, wobei der Tiefenbegrenzer zur Einstellung einer vorgesehenen Höhenlage des Steuerpiloten, insbesondere in Relation zu den Verlegeeinheiten, vorgesehen ist.According to a further development, the control pilot has a depth limiter, the depth limiter being provided for setting an intended altitude of the control pilot, in particular in relation to the laying units.

Es kann vorgesehen sein, dass der Tiefenbegrenzer einen Hydraulikzylinder zur Anpassung der Höhenlage des Steuerpiloten aufweist, wobei der Tiefenbegrenzer insbesondere gelenkig an den Steuerpiloten und/oder die mittlere Verlegeeinheit angebracht ist.Provision can be made for the depth gauge to have a hydraulic cylinder for adjusting the altitude of the pilot, the depth gauge being attached in particular in an articulated manner to the pilot and/or the central laying unit.

Gemäß einer Ausführungsvariante der Erfindung umfasst das Rohr- und/oder Kabelpflugsystem wenigstens ein, vorzugsweise zwei oder drei, Zugmittel, insbesondere Stahlseile, wobei der Kabelpflug wenigstens ein Verbindungsmittel zur Verbindung mit jedem vorgesehenen Zugmittel aufweist, wobei der Kabelpflug mittels des oder der Zugmittel durch das oder die Zugfahrzeuge ziehbar ist oder gezogen wird.According to one embodiment of the invention, the pipe and/or cable plow system comprises at least one, preferably two or three, traction means, in particular steel cables, with the cable plow having at least one connection means for connection to each traction means provided, with the cable plow being connected to the traction means by the or the towing vehicle is towable or is towed.

Bevorzugt ist das Verbindungsmittel an der mittleren Verlegeeinheit vorgesehen, insbesondere im oberen Bereich des Schwerts der mittleren Verlegeeinheit, und/oder am Tiefenbegrenzer. Der Zugpunkt, an welchem der Kabelpflug durch die Zugfahrzeuge gezogen wird, ist damit mittig am Kabelpflug angeordnet. Es kann vorgesehen sein, dass das Verbindungsmittel und damit der Zugpunkt, vorzugsweise knapp, oberhalb der Schwertbiegung des Schwerts der mittleren Verlegeeinheit vorgesehen ist.The connecting means is preferably provided on the middle laying unit, in particular in the upper area of the sword of the middle laying unit, and/or on the depth limiter. The towing point at which the cable plow is pulled by the towing vehicles is thus located in the middle of the cable plow. Provision can be made for the connecting means and thus the traction point to be provided, preferably just above the sword bend of the sword of the central laying unit.

Ferner kann vorgesehen sein, dass eine der Anzahl der Verlegeeinheiten entsprechende Anzahl an Verbindungsmitteln vorgesehen ist, wobei an jeder Verlegeeinheit ein Verbindungsmittel vorgesehen ist, wobei die Verbindungsmittel insbesondere jeweils im oberen Bereich der Schwerter angeordnet sind.Provision can also be made for a number of connecting means corresponding to the number of laying units to be provided, with a connecting means being provided on each laying unit, with the connecting means being arranged in particular in the upper region of the swords.

Besonders bevorzugt sind drei Verlegeeinheiten vorgesehen, wobei ein Verbindungsmittel am Tiefenbegrenzer, welcher an der mittleren Verlegeeinheit vorgesehen ist, angeordnet ist und die beiden weiteren Verbindungsmittel jeweils im oberen Bereich der Schwerter der beiden äußeren Verlegeeinheiten angeordnet sind.Three laying units are particularly preferably provided, with a connecting means being arranged on the depth limiter which is provided on the middle laying unit and the two other connecting means being arranged in the upper region of the swords of the two outer laying units.

Gemäß einer Weiterbildung der Erfindung kann vorgesehen sein, dass jede Leitungsführung über eine mechanische Verbindung mit dem zugehörigen Schwert der Verlegeeinheit verbunden ist, wobei die Leitungsführung als Verlegeschacht ausgebildet ist, wobei der Verlegeschacht einen Einlauftrichter aufweist. Vorzugsweise ist eine Öffnung des Einlauftrichters in Richtung der vorgesehenen Fahrtrichtung orientiert.According to a development of the invention, it can be provided that each line guide is connected to the associated sword of the laying unit via a mechanical connection, the line guide being designed as a laying shaft, with the laying shaft having an inlet funnel. An opening of the inlet funnel is preferably oriented in the direction of the intended direction of travel.

Gemäß einer besonders bevorzugten Ausbildungsvariante der Erfindung ist vorgesehen, dass der Kabelpflug eine horizontale Messerplatte zur, insbesondere starren, Verbindung der Verlegeeinheiten untereinander aufweist.According to a particularly preferred embodiment variant of the invention, it is provided that the cable plow has a horizontal blade plate for the, in particular rigid, connection of the laying units to one another.

Ein Vorteil der horizontalen Messerplatte besteht insbesondere darin, dass diese die Verlegeeinheiten untereinander stabilisiert, so dass eine äußerst präzise Verlegung der Leitungen mit kleinstmöglicher Toleranz ermöglicht wird. Zusätzlich wird durch die Messerplatte die Eindringtiefe des Kabelpflugs in den Untergrund minimiert. An der Erdoberfläche findet somit keine Bodenverdichtung statt. Die Leitungen werden durch den erfindungsgemäß ausgebildeten Kabelpflug in einem festgelegten Abstand zueinander und in einer festgelegten Tiefe verlegt.One particular advantage of the horizontal cutter plate is that it stabilizes the laying units among themselves, so that extremely precise laying of the lines with the smallest possible tolerance is made possible. In addition, the depth of penetration of the cable plow into the subsoil is minimized by the blade plate. There is therefore no soil compaction on the surface of the earth. The cables are laid at a fixed distance from one another and at a fixed depth by the cable plow designed according to the invention.

Es kann vorgesehen sein, dass die Verlegeeinheiten auf der Oberseite der horizontalen Messerplatte angebracht, insbesondere angeschweißt und/oder durch mechanische Verbindungselemente angebracht, sind.Provision can be made for the laying units to be attached, in particular welded and/or attached by mechanical connecting elements, to the upper side of the horizontal cutter plate.

Ferner kann vorgesehen sein, dass die horizontale Messerplatte einen rechteckigen Abschnitt und einen tannenbaumartigen Abschnitt aufweist, wobei der tannenbaumartige Abschnitt in der vorgesehenen Fahrtrichtung vor dem rechteckigen Abschnitt vorgesehen ist, und/oder wobei der tannenbaumartige Abschnitt in der vorgesehenen Fahrtrichtung spitz zuläuft, wobei die Außenkanten des tannenbaumartigen Abschnitts eine Schneidkante aufweisen und/oder ausbilden.Furthermore, it can be provided that the horizontal cutter plate has a rectangular section and a Christmas tree-like section, with the Christmas tree-like section being provided in front of the rectangular section in the intended direction of travel, and/or with the Christmas tree-like section tapering to a point in the intended direction of travel, with the outer edges of the fir-tree-like section have and/or form a cutting edge.

Gemäß einer Weiterbildung der Erfindung weist das Rohr- und/oder Kabelpflugsystem mindestens eine Grabenbildungseinheit, insbesondere eine Grabenfräse und/oder einen Bagger, zur Erzeugung einer Startgrube und/oder eines Leitgrabens für den Kabelpflug auf.According to a development of the invention, the pipe and/or cable plow system has at least one trench formation unit, in particular a trench cutter and/or an excavator, for creating a starting pit and/or a guiding trench for the cable plow.

Gemäß einer bevorzugten Ausführungsvariante der Erfindung ist vorgesehen, dass das Rohr- und/oder Kabelpflugsystem vertikale und/oder horizontale Vorschneidmesser zum Zerschneiden des Bodens aufweist, wobei die Vorschneidmesser am oder im Bereich des Steuerpiloten und/oder am oder im Bereich des Kabelpflugs angeordnet sind.According to a preferred embodiment of the invention, it is provided that the pipe and/or cable plow system has vertical and/or horizontal pre-cutting knives for cutting up the ground or in the area of the helm pilot and/or on or in the area of the cable plow.

In einer bevorzugten Ausführungsvariante zerschneiden die Vorschneidmesser beim Ziehen des Kabelpflugs durch den Untergrund den Boden seitlich der Startgrube und/oder des Leitgrabens, um den Boden zu lockern und/oder um den Boden derart zu zerkleinern, dass Füllmaterial für die Startgrube und/oder den Leitgraben gebildet wird, welches nach dem Einpflügen der Leitungen zum Füllen des Grabens verwendet wird oder werden kann. Der wesentliche Vorteil von derart zerkleinertem Boden als Füllmaterial liegt darin, dass dieser nach dem Pflügen die Startgrube und/oder den Leitgraben und/oder die gebildeten Erdrinne verfüllt, ohne dass Hohlräume um die Leitungen herum entstehen, die beispielsweise hinsichtlich des Wärmeabtransports bei verlegten Stromleitungen von Nachteil wären.In a preferred embodiment variant, when the cable plow is pulled through the subsoil, the pre-cutting knives cut the soil to the side of the starting pit and/or the guiding ditch in order to loosen the soil and/or to crush the soil in such a way that filling material for the starting pit and/or the guiding ditch is formed, which is or can be used to fill the trench after the lines have been plowed in. The main advantage of soil that has been comminuted in this way as filling material is that after plowing, it fills the starting pit and/or the guide ditch and/or the earth gully that has been formed, without cavities being formed around the lines, which, for example, with regard to heat dissipation when power lines are laid from disadvantage would be.

Bevorzugt sind vertikale Vorschneidmesser an der Auflageplatte des Steuerpiloten und/oder an seitlichen Flügeln am Steuerpiloten angeordnet. Insbesondere ist vorgesehen, dass die vertikalen Vorschneidmesser nach unten aus der Auflagefläche des Auflageplatte und/ nach unten aus den Flügeln hervorstehen. Besonders bevorzugt sind die vertikalen Vorschneidmesser entgegen der vorgesehenen Fahrtrichtung zueinander und/oder nach außen versetzt an der Auflageplatte und/oder an den Flügeln angeordnet.Vertical pre-cutting knives are preferably arranged on the support plate of the helm pilot and/or on side wings on the helm pilot. In particular, it is provided that the vertical pre-cutting knives protrude downwards from the support surface of the support plate and/from the wings.

Ferner können horizontale Vorschneidmesser am Kabelpflug und/oder am Steuerpiloten und/oder an seitlichen Flügeln am Steuerpilot und/oder an der oder den Führungen, insbesondere der Parallelführung, angeordnet sein. Bevorzugt sind mehrere übereinander angeordnete und/oder entgegen der vorgesehenen Fahrtrichtung zueinander versetzt angeordnete horizontale Vorschneidmesser vorgesehen.Furthermore, horizontal pre-cutting knives can be arranged on the cable plow and/or on the control pilot and/or on side wings on the control pilot and/or on the guide or guides, in particular the parallel guide. A plurality of horizontal pre-cutting knives arranged one above the other and/or offset relative to one another counter to the intended direction of travel are preferably provided.

Gemäß einer Ausführungsvariante der Erfindung kann vorgesehen sein, dass das Rohr- und/oder Kabelpflugsystem eine Stützplatte aufweist, wobei die Stützplatte zur, insbesondere starren, Verbindung der Verlegeeinheiten untereinander an den Verlegeeinheiten vorgesehen ist. Bevorzugt ist die Stützplatte insbesondere im oberen Bereich der Verlegeeinheiten angeordnet, bevorzugt parallel und/oder mit Abstand zur horizontalen Messerplatte.According to an embodiment variant of the invention, it can be provided that the pipe and/or cable plow system has a support plate, the support plate being provided on the laying units for the, in particular rigid, connection of the laying units to one another. The support plate is preferably in the upper part in particular Area of laying units arranged, preferably parallel and / or at a distance from the horizontal blade plate.

Das erfindungsgemäße Verfahren zum parallelen Einbringen von zwei oder mehreren Leitungen in den Untergrund wird mit einem erfindungsgemäßen Rohr- und/oder Kabelpflugsystem durchgeführt, wobei das Rohr- und/oder Kabelpflugsystem mindestens eine Grabenbildungseinheit zur Erzeugung einer Startgrube und/oder eines Leitgrabens für den Kabelpflug aufweist.The method according to the invention for installing two or more lines in parallel in the subsoil is carried out using a pipe and/or cable plow system according to the invention, the pipe and/or cable plow system having at least one trench formation unit for creating a starting pit and/or a guiding trench for the cable plow .

Das erfindungsgemäß Verfahren umfasst die Schritte:

  1. a) Erzeugen einer Startgrube für den Kabelpflug, insbesondere mittels der Grabenbildungseinheit, insbesondere einer Grabenfräse oder einem Bagger,
  2. b) Erzeugen eines Leitgrabens, insbesondere eines Leitgrabens mit konstanter Tiefe, für den Kabelpflug, insbesondere mittels der Grabenbildungseinheit, insbesondere einer Grabenfräse oder einem Bagger,
  3. c) Einführen oder Einbringen des Kabelpflugs auf Verlegetiefe in die Startgrube und/oder den Leitgraben,
  4. d) Gleichzeitiges Einpflügen von zwei oder mehr Leitungen in den Untergrund mittels des Kabelpflugs,
    • d1) wobei der Kabelpflug zum Einpflügen der Leitungen durch ein oder mehrere Zugfahrzeuge durch den Untergrund entlang einer vorgesehenen Fahrtrichtung gezogen wird,
    • d2) wobei die Zugfahrzeuge beim Ziehen des Kabelpflugs vom Kabelpflug beabstandet sind, und
    • d3) wobei der Steuerpilot in der vorgesehenen Fahrtrichtung vor den Verlegeeinheiten am Boden der Startgrube und/oder des Leitgrabens entlanggleitet, wobei die Höhenlage des Kabelpflugs beim Ziehen des Kabelpflugs durch das eine oder die mehreren Zugfahrzeuge im Untergrund mittels des Steuerpiloten auf einem vorgesehenen, insbesondere konstantem, Niveau gehalten wird, insbesondere indem durch den Steuerpiloten eine nach unten gerichtete Bewegung und/oder ein Nach-Unten-Kippen und/oder ein Nach-Vorne-Kippen des Kabelpflugs während des Verlegeprozesses, welches aus der Zugbewegung resultiert, verhindert wird.
The method according to the invention comprises the steps:
  1. a) Creation of a starting pit for the cable plow, in particular by means of the trench formation unit, in particular a trench cutter or an excavator,
  2. b) Creation of a guiding trench, in particular a guiding trench with a constant depth, for the cable plow, in particular by means of the trench formation unit, in particular a trench cutter or an excavator,
  3. c) inserting or inserting the cable plow to the laying depth in the starting pit and/or the guiding ditch,
  4. d) simultaneous plowing of two or more lines into the ground using the cable plow,
    • d1) where the cable plow for plowing in the lines is pulled by one or more towing vehicles through the subsoil in a planned direction of travel,
    • d2) wherein the towing vehicles are spaced apart from the cable plow when pulling the cable plow, and
    • d3) wherein the control pilot glides in the intended direction of travel in front of the laying units on the bottom of the starting pit and/or the guiding ditch, wherein the altitude of the cable plow when the cable plow is being pulled by the one or more towing vehicles in the underground by means of the control pilot on a provided, in particular constant , Level is maintained, in particular by a downward movement and / or a downward tilting and / or a forward tilting of the cable plow by the control pilot during the laying process, which results from the pulling movement, is prevented.

Die Vorteile des Verfahrens ergeben sich aus den vorstehenden Erläuterungen zum erfindungsgemäßen Rohr- und/oder Kabelpflugsystem.The advantages of the method result from the above explanations of the pipe and/or cable plow system according to the invention.

Ein wesentlicher Vorteil ergibt sich aus dem Zusammenwirken von Leitgraben und Steuerpilot. Der Steuerpilot gleitet beim Ziehen des Kabelpflugs und damit beim Pflügen auf dem Boden des Leitgrabens entlang und verhindert dadurch beispielsweise ein Abkippen des Kabelpflugs in den Untergrund mir der Folge einer immer größer werdenden Verlegetiefe. Der Steuerpilot sorgt somit im Zusammenspiel mit dem Leitgraben dafür, dass der Kabelpflug beim Einpflügen der Leitungen auf einem vorgesehenen, insbesondere konstanten Niveau verbleibt. Dadurch wird sichergestellt, dass die einzupflügenden Leitungen in vorgesehener, vorzugsweise konstanter Tiefe verlegt werden. Als weiterer Vorteil sorgt der Leitgraben im Zusammenspiel mit dem Steuerpiloten dafür, dass der Kabelpflug in der vorgesehenen Fahrtrichtung bewegt wird und nicht durch beispielsweise ungleichmäßiges Ziehen mehrerer Zugfahrzeuge in eine unerwünschte Richtung gelenkt wird. Dies wird zusätzlich unterstützt, wenn am Steuerpiloten die vorstehend beschriebene Auflageplatte vorgesehen ist, die insbesondere ein seitliches Verkippen des Kabelpflugs verhindert. Des Weiteren sorgt der Leitgraben für eine optimale Bodenverdrängung während des Einpflügens.A significant advantage results from the interaction of the guide ditch and the control pilot. When pulling the cable plow and thus plowing, the control pilot glides along the bottom of the guiding trench and thus prevents the cable plow from tipping over into the ground, for example, which would result in an ever-increasing installation depth. In cooperation with the guiding ditch, the control pilot thus ensures that the cable plow remains at a planned, in particular constant, level when plowing in the lines. This ensures that the lines to be plowed in are laid at the intended, preferably constant, depth. As a further advantage, the guide ditch, in cooperation with the control pilot, ensures that the cable plow is moved in the intended direction of travel and is not steered in an undesired direction by, for example, several towing vehicles being pulled unevenly. This is additionally supported if the support plate described above is provided on the control pilot, which in particular prevents the cable plow from tipping to the side. Furthermore, the guide ditch ensures optimal soil displacement during ploughing.

Gemäß einer Weiterbildung des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass die Zugfahrzeuge den Kabelpflug mittels je einer auf oder an dem Zugfahrzeug vorgesehenen Seilwinde durch den Untergrund ziehen.According to a further development of the method according to the invention, it can be provided that the towing vehicles pull the cable plow through the subsoil by means of a cable winch provided on or on the towing vehicle.

Ferner kann vorgesehen sein, dass das Rohr- und/oder Kabelpflugsystem vertikale und/oder horizontale Vorschneidmesser zum Zerschneiden des Bodens aufweist, wobei die Vorschneidmesser am oder im Bereich des Steuerpiloten und/der dessen Führung angeordnet sind, wobei die Vorschneidmesser beim Ziehen des Kabelpflugs durch das oder die Zugfahrzeuge durch den Untergrund den Boden seitlich der Startgrube und/oder seitlich des Leitgrabens lockern und/oder zerkleinern, insbesondere derart, dass Füllmaterial für die Startgrube und/oder den Leitgraben und/oder die Erdrinnen gebildet wird, welches nach dem Einpflügen der Leitungen zum Füllen von Startgrube und/oder Leitgraben und/oder Erdrinnen verwendet wird oder werden kann.Provision can also be made for the pipe and/or cable plow system to have vertical and/or horizontal pre-cutting knives for cutting up the ground, with the pre-cutting knives being arranged on or in the area of the pilot pilot and/or his guide, with the pre-cutting knives being pulled through by the cable plow the towing vehicle(s) loosen and/or crush the soil on the side of the launch pit and/or on the side of the control ditch through the subsoil, in particular in such a way that filling material for the launch pit and/or the control ditch and/or the gully is formed, which is or can be used after plowing in the lines for filling the starting pit and/or control ditch and/or gully.

Das Erzeugen des Leitgrabens hat den Vorteil, dass vorab die Beschaffenheit bzw. Pflügbarkeit des Bodens untersucht werden kann. Ferner hat das Erzeugen des Grabens den Vorteil, dass im Gelände liegende Drainagen oder sonstigen früher verlegten Komponenten noch vor dem Pflügvorgang (beim Vorfräsen oder Vorbaggern) auffindbar sind und deren Verlauf gekennzeichnet werden kann, um Schäden an der Drainage bzw. den Komponenten durch den Kabelpflug zu vermeiden.Creating the guide ditch has the advantage that the condition and ploughability of the soil can be examined in advance. Furthermore, the creation of the trench has the advantage that drainage or other previously laid components lying in the terrain can be found before the plowing process (when pre-milling or pre-digging) and their course can be marked in order to avoid damage to the drainage or components caused by the cable plow to avoid.

Insbesondere kann vorgesehen sein, dass mittels der Zugkraft der Zugfahrzeuge die Schwerter das Erdreich verdrängen und die Grabensohlen glätten, wodurch Hohlräume entstehen, in welche die Leitungen, insbesondere spannungsfrei, eingeführt werden können. Der Steuerpilot und das Schwert der mittleren Verlegeeinheit verlaufen entlang des Leitgrabens, insbesondere ohne weitere Bodenverdrängung. Die Schwerter der beiden äußeren Verlegeeinheiten verdrängen jeweils Bodenmaterial hin zum Graben, so dass der Graben dadurch wieder geschlossen wird. Dies wiederum hat zur Folge, dass lediglich Bodenmaterial an den Außenseiten der Schwerter der beiden äußeren Verlegeeinheiten verdrängt wird, so dass insgesamt nicht mehr Bodenmaterial verdrängt werden muss, als bei einem einzelnen Schwert.In particular, provision can be made for the swords to displace the soil and smooth the trench bottoms by means of the pulling force of the towing vehicles, thereby creating cavities into which the lines can be inserted, in particular without tension. The control pilot and the sword of the middle laying unit pass along the guide trench, especially without further soil displacement. The swords of the two outer laying units each displace soil material towards the ditch, so that the ditch is closed again as a result. This in turn means that only soil material is displaced on the outer sides of the swords of the two outer laying units, so that overall no more soil material has to be displaced than with a single sword.
