Description

Die Erfindung betrifft ein Verfahren zum Sanieren des aus Schotter sowie aus darunter befindlichen Bodenmaterialien bestehenden mehrschichtigen Unterbaus von aus Schwellen und Schienen bestehenden Gleisen bei Bahnstrecken nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for rehabilitating existing of gravel and from underlying soil materials multilayer substructure consisting of sleepers and rails tracks on rail lines according to the preamble of patent claim 1.

Bahnstrecken bestehen aus einem mehrschichtigen Unterbau, auf welchem sich die Gleise befinden. Diese Gleise bestehen dabei aus den Schwellen und aus den Schienen. Der mehrschichtige Unterbau besteht zunächst aus Bodenschichten. Hier handelt es sich insbesondere um eine Planumsschutzschicht, um eine Frostschutzschicht sowie um ggf. um weitere Schichten. Auf diesen Bodenschichten befindet sich dann eine Schotterschicht. Diese dient der Aufnahme des Gleises.Railways consist of a multi-layered substructure on which the tracks are located. These tracks consist of the sleepers and the rails. The multi-layer substructure initially consists of soil layers. These are, in particular, a protective cover layer, an antifreeze layer and possibly further layers. On these soil layers is then a gravel layer. This serves to receive the track.

Der vorbeschriebene Unterbau muß von Zeit zu Zeit saniert werden. Das Gleis selbst wird dabei nicht notwendigerweise immer mit erneuert. Es kann aber auch gleichzeitig miterneuert oder teilerneuert werden. Es gibt dabei verschiedene Verfahren zum Sanieren und Erneuern von Unterbauschichten und Gleisanlagen.The above-described substructure must be rehabilitated from time to time. The track itself is not necessarily always renewed. It can also be renewed or partially renewed at the same time. There are various procedures for renovation and renewal of underground layers and track systems.

Aus DE 31 17 898 A1 ist ein Verfahren bekannt, bei dem ein aus mehreren Arbeitswagen bestehender Arbeitszug zum Ausbau sowie Einbau des Gleises, des Schotters sowie der Bodenmaterialien eingesetzt wird. Dabei erfolgt das Entfernen des vollständigen Unterbaus durch eine Räumvorrichtung und eine Ausgabestation.Out DE 31 17 898 A1 a method is known in which a work truck consisting of several work cars for the removal and installation of the track, the ballast and the soil materials is used. The removal of the complete substructure is carried out by a broaching device and an output station.

EP 2 071 077 A2 beschreibt ein Verfahren zum Erneuern des mehrschichtigen Unterbaus von Gleisen, bei dem auf dem Gleis ein Arbeitswagen kontinuierlich vorwärtsbewegt wird, das Gleis in ein Kurzjoch sowie in Langjoche aufgetrennt wird, zunächst das Kurzjoch und anschließend die Langjoche entsprechend der Vorwärtsbewegung desArbeitswagens ausgebaut werden, nach dem Ausbau der Joche der Unterbau erneuert wird un schließlich die Joche wieder eingebaut werden. EP 2 071 077 A2 describes a method for renewing the multi-layered substructure of tracks, in which on the track a work cart is continuously advanced, the track is split into a short yoke and in long yokes, first the short yoke and then the long yokes are removed according to the forward movement of the working carriage, after removal the yokes of the substructure will be renewed and finally the yokes will be reinstalled.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren zum Sanieren des aus Schotter sowie aus darunter befindlichen Bodenschichten bestehenden mehrschichtigen Unterbaus von aus Schwellen und Schienen bestehenden Gleisen bei Bahnstrecken zu schaffen.The invention has for its object to provide an improved method for rehabilitating existing of ballast and from underlying soil layers multi-layer substructure consisting of sleepers and rails tracks on rail lines.

Die technische Lösung ist gekennzeichnet durch die Merkmale im Kennzeichen des Anspruchs 1.The technical solution is characterized by the features in the characterizing part of claim 1.

Dadurch ist ein verbessertes Verfahren zum Sanieren des aus Schotter sowie aus darunter befindlichen Bodenschichten bestehenden mehrschichtigen Unterbaus von aus Schwellen und Schienen bestehenden Gleisen bei Bahnstrecken geschaffen, welches sich durch eine einfache technische Realisierung unter Verwendung von flexibel einsetzbaren Arbeitswagen mit entsprechenden Maschinen auszeichnet. Damit ist eine Umbautechnik für den Gleisumbau mit Untergrundsanierung und Bettungsreinigung bzw. Bettungserneuerung mit logistischen Vorteilen geschaffen. Das Herzstück ist dabei der erfindungsgemäße Kopf-Arbeitswagen entweder an der Spitze oder am Ende des Arbeitszuges. Dieser Kopf-Arbeitswagen als logistische Einheit ist für das Handling des Gleises sowie für den Ausbau und für den Einbau des Schotters sowie der Bodenmaterialien verantwortlich. So ist der Kopf-Arbeitswagen zunächst dafür vorgesehen, daß das jochweise ausgebaute Gleis entlang dieses Kopf-Arbeitswagens nach hinten transportiert und dort entweder im Kopf-Arbeitswagen oder vorzugsweise in einem der dahinter befindlichen Arbeitswagen gelagert wird. Dabei wird das Gleis jochweise durch den Kopf-Arbeitswagen hindurchgeschoben. Das Durchschieben des Gleises kann dabei auf unterschiedliche Art und Weise erfolgen. Während des Durchschiebens wird der Ausbauprozeß und erforderlichenfalls der Einbauprozeß unterbrochen. Die Unterbrechung hat jedoch selbst für den Fall, daß der Einbauprozeß kurzfristig unterbrochen werden müßte, keine Diskontinuität des Arbeitsablaufes zur Folge, da keine Schichtunterbrechung erfolgt. Insbesondere wird kein neuer Ansatz der Schichten erforderlich, da die Einbaueinheiten für den Schotter sowie für die Bodenmaterialien lediglich an einer bestimmten Stelle verharren.As a result, an improved method for refurbishing existing of gravel and underlying soil layers consisting of multi-layer substructure consisting of sleepers and rails tracks on railways created, which is characterized by a simple technical realization using flexible working car with appropriate machinery. Thus, a conversion technology for the track renewal with subsurface remediation and ballast cleaning or ballast renewal with logistical advantages is created. The heart of this is the inventive head-trolley either at the top or at the end of the work train. As a logistical unit, this head-driven utility vehicle is responsible for the handling of the track as well as for the removal and installation of the ballast and ground materials. Thus, the head-work car is initially designed so that the yoke-mounted track transported along this head-work vehicle to the rear and there is stored either in the head-work car or preferably in one of the work car behind it. The track is then pushed through the head work car. The passage of the track can be done in different ways. During the pushing through the expansion process and, if necessary, the installation process is interrupted. However, even in the event that the installation process would have to be interrupted for a short time, the interruption does not result in any discontinuity of the workflow since there is no shift interruption. In particular, no new approach of the layers is required because the installation units for the ballast and for the soil materials remain only at a certain point.

Der erfindungsgemäße Kopf-Arbeitswagen erlaubt einen Gleisumbau und gleichzeitige Untergrundsanierung, wobei sämtliche auszubauenden und einzubauenden Bodenschichten von einem Lagerplatz aus umgeschlagen werden können. Gleichzeitig werden die alten Gleise aus- und wieder eingebaut. Sie können aber auch durch neue Gleise ersetzt werden. Die Gleise können dabei aus entgegengesetzter Richtung zu den Bodenstoffen dem Kopf-Arbeitswagen zugeführt werden, da sie logistisch unabhängig von den Bodenschichten sind. Um die Maschinenkonstruktion einfach zu halten, werden die Ausbau- und Einbauarbeiten der Unterbauschichten bei ausgebautem Gleis durchgeführt. Die Besonderheit liegt dabei in der Art des Ausbaus der Unterbauschichten sowie in dem jochweisen Einbau des alten bzw. eines neuen Gleises.The head-working car according to the invention allows a track renewal and simultaneous underground remediation, with all to be built and installed soil layers can be handled from a storage place. At the same time, the old tracks are removed and reinstalled. But they can also be replaced by new tracks. The tracks can be fed from the opposite direction to the ground materials the head-car, since they are logistically independent of the soil layers. In order to keep the machine design simple, the removal and installation work of the substructure layers are carried out with the track dismantled. The special feature is in the type of expansion of the underground layers and in the yokewise installation of the old or a new track.

Dadurch ist ein Gesamtablauf in einem kontinuierlichen Umbauverfahren im Bereich der Bodenschichten geschaffen. Dabei sind sämtliche Schichten in einer Aufstellung hinter dem Kopf-Arbeitswagen angeordnet. Dies wird durch die Verwendung von Materialförderwagen mit reversibler Übergabetechnik ermöglicht. Dies hat den Vorteil, daß sämtliche Materialien der Unterbauschichten (altes Bodenmaterial / neues Bodenmaterial / alter Schotter / aufgearbeiteter Schotter / neuer Schotter) aus einer Arbeitsrichtung zu- und abgeführt werden können. Es ist somit für alle Boden- und Schottermaterialien nur ein logistischer Arbeitsplatz erforderlich.This creates an overall process in a continuous conversion process in the area of soil layers. All layers are arranged in a line behind the head-work car. This is made possible by the use of material trolleys with reversible transfer technology. This has the advantage that all materials of the subgrade layers (old soil material / new soil material / old gravel / refurbished gravel / new gravel) can be supplied and removed from one working direction. Thus, only one logistical workstation is required for all soil and ballast materials.

Insgesamt können sämtliche Materialien ersetzt werden oder durch eine gezielte Aufarbeitung einzelner Materialien wiederverwendet werden. Die auszubauenden Materialien können dabei zu ihren Bestimmungsorten, nämlich den entsprechenden Arbeitswagen entsprechend transportiert werden. So kann der auszubauende und aufzuarbeitende Schotter mittels einer Aushubeinheit einer Aufgabestation aufgegeben werden. Der Schotter kann dann über ein Förderband zu einer Bettungsreinigungseinheit eines entsprechenden Arbeitswagens weitertransportiert werden. In dieser Bettungsreinigungseinheit wird der Schotter gemäß dem zu wählenden Aufarbeitungsverfahren recyclet und erforderlichenfalls zusätzlich gewaschen. Die Waschung kann hierbei optional erfolgen. Die nicht wieder verwendbaren Schmutz- und Feinanteile des Schotters können dann von der Reinigungseinheit an entsprechende Bunkerwagen weitertransportiert werden. Die wieder verwendbaren und recycleten bzw. gewaschenen Schottermassen werden dann über Förderbänder zurück zur Einbaueinheit des Kopf-Arbeitswagens transportiert. Hier werden sie auf die Unterbauschicht aufgebracht und planiert und erforderlichenfalls verdichtet.Overall, all materials can be replaced or reused by a specific processing of individual materials. The materials to be removed can be transported to their destinations, namely the corresponding work car accordingly. Thus, the gravel to be removed and worked up can be abandoned by means of a lifting unit of a loading station. The ballast can then be transported on a conveyor belt to a ballast cleaning unit of a corresponding work car. In this ballast cleaning unit, the ballast is recycled according to the work-up procedure to be selected and, if necessary, additionally washed. The washing can be done optionally. The non-reusable dirt and fines of the ballast can then be transported by the cleaning unit to appropriate bunker cars. The reusable and recycled or washed ballast masses are then transported via conveyor belts back to the installation unit of the head-working car. Here they are applied to the base coat and leveled and compacted if necessary.

Entsprechend werden die alten Bodenschichten (meist Frostschutzschicht und Planumsschutzschicht) mittels einer Aushubeinheit auf eine zugeordnete Aufgabestation aufgegeben. Von dort werden die alten Bodenschichten über Förderbänder längs der Arbeitswagen der verschiedenen Stationen der Gesamtzugeinheit hinweg transportiert. Der Transport endet für die ausgebauten Bodenschichten in deren Bunkerwagen. Gleichzeitig wird das neue Bodenmaterial von ihren Bunkerwagen über die Förderwagen zur entsprechenden Einbauheit des Kopf-Arbeitswagens transportiert. Zur Übergabe der Stoffe aus dem Bunkerwagen auf die Förderbänder ist es dabei sinnvoll und hilfreich, einen Übergabewagen zwischenzuschalten. Mit der entsprechenden Einbaueinheit des Kopf-Arbeitswagens wird das neue Bodenmaterial (meist Frostschutzschicht und Planumsschutzschicht) eingebaut, planiert und erforderlichenfalls verdichtet. Es können aber auch andere Abläufe gewählt werden als der zuvor beschriebene Ablauf. Ziel ist eine komplette Erneuerung der Unterbauschichten. Hierzu müssen lediglich die Förderbänder und die Arbeitswagen in der Zuführung entsprechend umgestellt werden.Accordingly, the old soil layers (usually antifreeze layer and layer protection layer) are abandoned by means of a lifting unit on an associated feeding station. From there, the old soil layers are transported via conveyor belts along the work cars of the various stations of the total tractor unit. The transport ends for the excavated soil layers in their bunker cars. At the same time, the new soil material is transported from their bunker wagons over the trolleys to the appropriate installation of the head-work wagon. In order to transfer the substances from the bunker trolley to the conveyor belts, it is useful and helpful to interpose a transfer trolley. With the appropriate installation unit of the Kopf-Arbeitswagens the new soil material (usually frost protection layer and layer protection layer) is installed, leveled and compacted if necessary. However, other processes can be selected than those previously described procedure. The goal is a complete renewal of the underground layers. For this purpose, only the conveyor belts and the work car in the feeder must be changed accordingly.

Die zuvor beschriebene Aushubeinheit löst sowohl die Schotterschicht als auch die alte Bodenschicht. Die Schotterschicht wird hierbei der Aufgabestation mittels der Aushubeinheit übergeben. Die alte Bodenschicht wird über eine entsprechende Aufgabestation ebenfalls mittels der Aushubeinheit übergeben. Die Aushubeinheit kann dabei auf verschiedenen Techniken basieren. Die einfachste Technik ist eine Baggereinheit. Es können aber auch andere mögliche Techniken zur Anwendung kommen, beispielsweise Förderketten, Fräsen, Schaufelräder oder aber auch andere denkbare Lösungen, mittels denen der Aushub gelöst und verladen werden kann.The excavation unit described above solves both the gravel layer and the old soil layer. The ballast layer is hereby transferred to the loading station by means of the excavating unit. The old soil layer is also transferred via a corresponding feed station by means of the excavation unit. The excavation unit can be based on different techniques. The simplest technique is an excavator unit. However, other possible techniques may also be used, for example conveyor chains, milling machines, paddle wheels or other conceivable solutions by means of which the excavated material can be released and loaded.

Mit der vorbeschriebenen Technik kann gleichzeitig auch das Gleis ausgebaut und wieder eingebaut werden. Es kann hierbei sowohl das alte Gleis ausgebaut und anschließend wieder eingebaut werden. Alternativ ist es auch möglich, daß das alte Gleis gegen ein neues Gleis ausgetauscht werden kann. Auch eine Teilerneuerung ist möglich. Falls eine gleichzeitige Gleisstoffauswechslung im Sinne einer Gleiserneuerung erfolgen soll, werden diese neuen Gleise vorzugsweise aus entgegengesetzter Richtung der Maschine zugeführt. Hierbei ist es möglich, einzelne oder alle Gleisbaustoffe zu erneuern. Die alten Gleisbaustoffe werden auf die Arbeitswagen aufgeladen, während die neuen Gleisbaustoffe abgeladen und eingebaut werden. Auf den Arbeitswagen kann erforderlichenfalls auch eine Ummontage von alten auf neue Gleisstoffe erfolgen. Das Längsverfahren auf den Arbeitswagen erfolgt mittels am Markt vorhandener Techniken wie Portalkräne oder dgl. Zum Auf- und Abladen der Gleisbaustoffe kann ebenfalls eine Standardtechnik, nämlich der sogenannte Schienenkran verwendet werden.At the same time, the track can be removed and reinstalled using the technology described above. It can be expanded both the old track and then reinstalled. Alternatively, it is also possible that the old track can be replaced with a new track. Partial renewal is also possible. If a simultaneous track material replacement in the sense of a track renewal should take place, these new tracks are preferably fed from the opposite direction of the machine. Here it is possible to renew individual or all track construction materials. The old track construction materials are loaded onto the work cars while the new track construction materials are unloaded and installed. If necessary, the work car can also be converted from old to new track materials. The longitudinal process on the work car takes place by means of existing on the market techniques such as gantry cranes or the like. For loading and unloading the track construction materials can also be a standard technique, namely the so-called rail crane can be used.

Vorzugsweise wird gemäß der Weiterbildung in Anspruch 2 das Gleis durch den Kopf-Arbeitswagen hindurch nach hinten transportiert. Dies bedeutet, daß das Gleis gewissermaßen in den Schlund des Kopf-Arbeitswagens eintaucht und von dort nach hinten transportiert wird. Dies kann auch unterflurig erfolgen.Preferably, according to the embodiment in claim 2, the track is transported through the head-work car to the rear. This means that the track is in a sense immersed in the gullet of the head-work vehicle and is transported from there to the rear. This can also be done underfloor.

Gemäß der Weiterbildung in Anspruch 3 kann das Gleis entweder vom erfindungsgemäßen Kopf-Arbeitswagen aus ausgebaut und eingebaut werden. Es ist aber auch möglich, daß der Aus- oder Einbau des Gleises von einem Nachbargleis aus erfolgen kann. Für den Fall, daß ein neues Gleis eingebaut wird, kann dies auch von einer auf dem Gleis verfahrbaren, separaten Arbeitseinheit durchgeführt werden.According to the embodiment in claim 3, the track can either be removed and installed by the inventive head-work car. But it is also possible that the removal or installation of the track can be done from a neighboring track. In the event that a new track is installed, this can also be done by a movable on the track, separate work unit.

Um den Transport des Gleises durch den Kopf-Arbeitswagen hindurch problemlos durchführen zu können, werden gemäß der Weiterbildung in Anspruch 4 die Aufgabestationen für den Schotter sowie für die Bodenmaterialien vorzugsweise angehoben. Diese Anhebung ermöglicht das Durchfördern der Gleise durch die erfindungsgemäße Aushubeinheit unterhalb der angehobenen Baugruppen.In order to be able to easily carry out the transport of the track through the head-work vehicle, according to the embodiment of claim 4, the feeding stations for the ballast and for the soil materials are preferably raised. This increase allows the conveyance of the tracks through the excavation unit according to the invention below the raised assemblies.

Der Transport des Schotters sowie der Bodenmaterialien erfolgt gemäß der Weiterbildung in Anspruch 5 mittels Förderbändern. Die Gleisbaustoffe, nämlich die Gleisjoche bzw. die Schienen und Schwellen können dabei aus entgegengesetzter Richtung zu diesen Bodenstoffen der Kopf-Arbeitsmaschine zugeführt werden, da sie logistisch unabhängig von den Bodenschichten sind. Die zuvor beschriebenen Förderbandanlagen können beliebig angeordnet werden, um die entsprechenden Materialien zu ihrer Aufarbeitungsstätte oder Bunkerstätte zu transportieren.The transport of the ballast and the soil materials is carried out according to the embodiment in claim 5 by means of conveyor belts. The track construction materials, namely the track yokes or the rails and sleepers can be fed from the opposite direction to these base materials of the head-working machine because they are logistically independent of the soil layers. The conveyor belt systems described above can be arranged arbitrarily in order to transport the corresponding materials to their processing station or bunker.

Gemäß der Weiterbildung in Anspruch 6 sind die Förderbänder derart verstellbar, daß eine reversible Transportrichtung realisierbar ist.According to the embodiment in claim 6, the conveyor belts are adjustable so that a reversible transport direction can be realized.

Die Weiterbildung gemäß Anspruch 7 schlägt verschiedene Lagerungs- und Aufbereitungsschritte für ausgebaute, recycelte und/oder neue Schotter- bzw. Bodenmaterialien sowie für die nicht verwendbaren Schmutz- und Feinanteile bzw.

Der Arbeitszug, wie er in Fig. 1 dargestellt ist, besteht aus einer Vielzahl von Arbeitswagen. Zur besseren Darstellung ist der in Fig. 1 gezeigte Arbeitszug insgesamt in vier Abschnitte unterteilt und übereinander gezeigt. Dabei ist die zweite Darstellung links an die oberste Darstellung anzufügen, die dritte Darstellung links an die zweite Darstellung anzufügen etc.The work train, as in Fig. 1 is shown, consists of a variety of work cars. For better representation, the in Fig. 1 shown Arbeitszug divided into four sections and shown one above the other. The second representation is to be added on the left to the top representation, the third representation on the left to be added to the second representation, etc.

Das Herzstück des Arbeitszuges ist der Kopf-Arbeitswagen 1 entweder an der Spitze oder am Ende des Arbeitszuges. Dieser Kopf-Arbeitswagen 1 weist eine Aushubeinrichtung 2 in Form eines Baggers auf. Weiterhin sind zwei Aufgabestationen 3, 4 sowie zwei Einbaueinrichtungen 5, 6 vorgesehen.The heart of the work train is the head work car 1 either at the top or at the end of the work train. This head work cart 1 has an excavating device 2 in the form of an excavator. Furthermore, two feed stations 3, 4 and two mounting devices 5, 6 are provided.

Die Funktionsweise des Arbeitszuges ist wie folgt:

  • Zunächst werden die aus Schwellen 7 und Schienen 8 bestehenden Gleise 9 ausgebaut. Dies kann durch den Kopf-Arbeitswagen 1 erfolgen aber auch durch eine separate Arbeitswageneinheit auf dem gleichen Gleis 9 oder auf einem Nachbargleis. Auf jeden Fall wird das jochweise ausgebaute Gleis 9 vorzugsweise mittels der Aushubeinrichtung 2 durch den Kopf-Arbeitswagen 1 hindurch nach hinten transportiert, wie dies in den Fig. 3a bis 3c erkennbar ist. Die Aufgabestationen 3, 4 sowie Einbaueinrichtungen 5, 6 sind dabei nach oben gefahren.
The working of the work train is as follows:
  • First, consisting of sleepers 7 and 8 rails 9 are removed. This can be done by the head work car 1 but also by a separate work car unit on the same track 9 or on a neighboring track. In any case, the yokewise developed track 9 is preferably transported by means of the excavating device 2 through the head-work car 1 through to the rear, as shown in the Fig. 3a to 3c is recognizable. The feeding stations 3, 4 and installation devices 5, 6 have gone up here.

Nach dem Ausbau des Gleises 9 und seines Transportes nach hinten sorgt zunächst die Aushubeinrichtung 2 zum Ausheben des Schotters 10. Die Aushubeinrichtung 2 gibt dabei den ausgebauten Schotter 10 der Aufgabestation 3 auf. Ausgehend von dieser Aufgabestation 3 wird der Schotter 10 mittels eines Förderbandes 11 einem Arbeitswagen 12 zur Schotteraufbereitung zugeführt. In dieser kann der Schotter 10 recyclet und ggf. zusätzlich gewaschen werden, wobei die Waschung optional erfolgen kann. Die nicht wieder verwendbaren Schmutz- und Feinanteile des Schotters 10 werden von dem Arbeitswagen 12 zu den Arbeitswagen 13 transportiert und dort gebunkert. Die wieder verwendbaren und recycleten sowie ggf. der gewaschene Schotter werden über Förderbänder 14 zurück zum Kopf-Arbeitswagen 1 transportiert und der Einbaueinrichtung 5 für den wieder aufbereiteten Schotter 10 aufgegeben.After the expansion of the track 9 and its transport to the rear, first the excavating device 2 ensures the excavation of the ballast 10. The excavating device 2 releases the excavated ballast 10 of the loading station 3. Starting from this feeding station 3, the ballast 10 is fed by means of a conveyor belt 11 to a work cart 12 for ballast processing. In this, the ballast can be recycled 10 and possibly additionally washed, the washing can optionally be done. The non-reusable dirt and fines of the ballast 10 are transported from the work car 12 to the work car 13 and bunkered there. The reusable and recycled as well as possibly the washed ballast are transported via conveyor belts 14 back to the head-work car 1 and the installation device 5 abandoned for the recycled ballast 10.

Nach dem Ausbau des Schotters 10 wird das darunter befindliche Bodenmaterial 15 (Planumsschutzschicht sowie ggf. Frostschutzschicht) mittels der Aushubeinrichtung 2 ausgehoben und der Aufgabestation 4 des Kopf-Arbeitswagens 1 aufgegeben. Von dort aus erfolgt der Transport des alten Bodenmaterials 15 mittels Förderbändern 16 über sämtliche Arbeitswagen hinweg bis zu den Arbeitswagen 17, wo die alten Bodenmaterialien 15 gebunkert werden. Der Transport für die ausgebauten Bodenmaterialien 15 endet dort in diesen Bunkerwagen. Gleichzeitig werden neue Bodenmaterialien 15 von ihren Arbeitswagen 18 über entsprechende Förderbänder 19 zur Einbaueinrichtung 6 des Kopf-Arbeitswagens 1 transportiert. Zur Übergabe der neuen Bodenmaterialien aus ihren Bunkerwagen auf die Förderbänder 19 ist es sinnvoll und hilfreich, einen Übergabewagen 20 zwischenzuschalten. Mit der Einbaueinrichtung 6 wird das neue Bodenmaterial 15 eingebaut, planiert und erforderlichenfalls verdichtet. Anschließend wird mittels der Einbaueinrichtung 5 des Kopf-Arbeitswagens 1 der Schotter 10 eingebaut. Zusätzlich kann in den mehrschichtigen Unterbau noch ein Vlies eingebaut werden.After removal of the ballast 10, the underlying soil material 15 (surface protection layer and possibly frost protection layer) is excavated by means of the excavating device 2 and the task station 4 of the head-working vehicle 1 abandoned. From there, the transport of the old soil material 15 by means of conveyor belts 16 over all work cars away up to the work car 17, where the old soil materials 15 are bunkered. The transport for the excavated soil materials 15 ends there in this bunker car. At the same time, new floor materials 15 are transported by their work car 18 via corresponding conveyor belts 19 to the installation device 6 of the head work cart 1. To transfer the new soil materials from their bunker cars on the conveyor belts 19, it makes sense and helpful to interpose a transfer car 20. With the installation device 6, the new soil material 15 is installed, leveled and, if necessary, compacted. Subsequently, the ballast 10 is installed by means of the installation device 5 of the head-working vehicle 1. In addition, a fleece can be installed in the multi-layered substructure.

Schließlich wird das Gleis 9 wieder eingebaut. Es kann dabei das alte, jochweise ausgebaute Gleis 9 verwendet werden. Zu diesem Zweck wird das Gleis 9 durch den Kopf-Arbeitswagen 1 hindurch nach vorne hin zur Einbaustelle transportiert.Finally, the track 9 is reinstalled. It can be used while the old, yoke-way track 9. For this purpose, the track 9 is transported through the head-work car 1 through to the front to the installation site.

Gemäß der Variante in den Fig. 4a und 4b ist ein separater Gleiswagen 21 vorgesehen. Dieser baut ein neues Gleis 9 ein. Zu diesem Zweck befindet sich der Kopf-Arbeitswagen 1 am Ende des Arbeitszuges.According to the variant in the Fig. 4a and 4b a separate railcar 21 is provided. This builds a new track 9. For this purpose, the head-work car 1 is at the end of the work train.
