Description

Die Erfindung betrifft ein Verfahren zur Planumsanierung einer Gleisbettung gemäß den im Oberbegriff von Anspruch 1 angeführten Merkmalen.The invention relates to a method for leveling a track bed according to the features cited in the preamble of claim 1.

Gemäß EP 2 025 810 ist es bereits bekannt, eine oberste Schichte der Schotterbettung für eine Wiederverwertung aufzunehmen. Der dabei bei der Reinigung anfallende Kies wird auf die restliche Schotterbettung abgeworfen und durch eine nachfolgende zweite Räumvorrichtung gemeinsam mit wieder verwertbarem Kies aufgenommen. Dieser wird hinter einer dritten Räumvorrichtung auf das freigelegte Erdplanum zur Bildung einer untersten Schichte der neu gebildeten und gereinigten Schotterbettung abgeworfen.According to EP 2 025 810 It is already known to include a top layer of ballast bed for recycling. The resulting during the cleaning gravel is dropped on the remaining ballast bed and added by a subsequent second clearing device together with reusable gravel. This is dropped behind a third clearing device on the exposed Erdplanum to form a lowermost layer of newly formed and cleaned ballast bedding.

Durch EP 2 257 673 ist es auch bekannt, den bei einer ersten Reinigung anfallenden Kies auf der Schotterbettung zwischen zu lagern. Dieser wird zusammen mit noch verwertbarem Kies der Schotterbettung aufgenommen und zur Bildung einer Kiesschicht auf ein freigelegtes Erdplanum abgeworfen.By EP 2 257 673 It is also known to store the incurred during a first cleaning gravel on the ballast between. This is taken up together with still usable gravel of the ballast bedding and dropped to form a layer of gravel on an uncovered Erdplanum.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens der eingangs genannten Art, mit dem die Qualität der Zwischenschicht optimierbar ist.The object of the present invention is now to provide a method of the type mentioned, with which the quality of the intermediate layer can be optimized.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren der gattungsgemäßen Art dadurch gelöst, dass der verwertbare Abraum mit Kies ergänzt wird.This object is achieved by a method of the generic type in that the usable overburden is supplemented with gravel.

Mit diesem Verfahrensschritt besteht die Möglichkeit, das in unterschiedlicher Zusammensetzung und/oder Menge anfallende verwertbare Abraummaterial für eine weitgehend gleichmäßige Qualität und auch eine gleichbleibende Höhe der Zwischenschicht bedarfsweise zu ergänzen.With this method step, it is possible to supplement the recoverable in different composition and / or amount recyclable space material for a substantially uniform quality and also a constant height of the intermediate layer, if necessary.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claims and the drawing description.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen:In the following the invention will be described with reference to an embodiment shown in the drawing. Show it:

Fig.1 eine schematisch vereinfachte Seitenansicht einer Maschine zur Planumsanierung, und Fig. 2 eine vergrößerte, schematische Darstellung einer mehrstufigen Materialeinbringung. Fig.1 a simplified schematic side view of a machine for rebuild, and Fig. 2 an enlarged, schematic representation of a multi-stage material introduction.

Eine in Fig. 1 nur zum Teil dargestellte Maschine 1 ist auf einem Gleis 2 in einer Arbeitsrichtung 3 verfahrbar. Für die Aufnahme einer oberen Schotterlage 4 ist eine erste Räumkette 5 vorgesehen. An diese schließen Förderbänder 6 zum Transport des aufgenommenen Schotters 9 zu einer Siebanlage an.An in Fig. 1 only partially illustrated machine 1 is movable on a track 2 in a direction of work 3. For receiving an upper ballast layer 4, a first clearing chain 5 is provided. At this close conveyor belts 6 for transporting the recorded ballast 9 to a screening plant.

Eine nach dem Einsatz der ersten Räumkette 5 unterhalb der oberen Schotterlage 4 verbleibende Restverwertungslage 7 wird durch eine zweite Räumkette 8 als verwertbarer Abraum 10 aufgenommen und gegebenenfalls unter Hinzufügung von Zuschlagstoffen mit weiterem Abraum, der von der genannten Siebanlage zur Reinigung des Schotters 9 anfällt, ergänzt.A remaining after the use of the first clearing chain 5 below the upper gravel layer 4 remaining recycling layer 7 is received by a second Räumkette 8 as recyclable overburden 10 and optionally with the addition of aggregates with further overburden resulting from said screen for cleaning the ballast 9.

Wie insbesondere in Fig. 2 ersichtlich, wird der verwertbare Abraum 10 an einer ersten Abwurfstelle 13 auf ein freigelegtes Erdplanum 11 abgeworfen und durch eine Vorrichtung 12 zur Herstellung einer Zwischenschicht 14 planiert und verdichtet. Auf diese wird eine Vlieslage 15 aufgebracht.As in particular in Fig. 2 can be seen, the usable overburden 10 is dropped at a first discharge point 13 on an exposed Erdplanum 11 and leveled by a device 12 for producing an intermediate layer 14 and compacted. On this a nonwoven layer 15 is applied.

Unmittelbar hinter der Vorrichtung 12 befindet sich eine zweite Abwurfstelle 16 zum Abwurf von Kies 17, der durch eine weitere Vorrichtung 18 zur Herstellung einer Planumschutzschicht 19 planiert und verdichtet wird. Im Bereich der zweiten Abwurfstelle 16 befindet sich eine der besseren Übersicht halber nicht dargestellte Ablenkvorrichtung, durch die in variabler Menge Kies 17 auf ein Verteilförderband 20 umlenkbar ist. Dieser Kies 17 wird anschließend über eine dritte Abwurfstelle 21 unmittelbar vor der Vorrichtung 12 zur Vermischung mit dem Abraum 10 abgeworfen.Immediately behind the device 12 is a second discharge point 16 for the discharge of gravel 17, which is leveled and compacted by a further device 18 for producing a Planumschutzschicht 19. In the area of the second discharge point 16 there is a deflection device, not shown for the sake of clarity, through which gravel 17 can be deflected onto a distribution belt 20 in a variable amount. This gravel 17 is then dropped off via a third discharge point 21 immediately in front of the device 12 for mixing with the overburden 10.

Als letzter Schritt der Planumsanierung erfolgt die Ablage einer weiteren Vlieslage 15 sowie ein Abwurf des gereinigten Schotters 9, auf den schließlich das Gleis 2 abgelegt wird.As a last step of the plan remediation, the storage of a further nonwoven layer 15 and a discharge of the cleaned ballast 9 takes place, on which finally the track 2 is deposited.

Claims (5)

  1. A method of formation rehabilitation of a track bed, including the following features:
    a) the track bed is removed in two stages in the shape of an upper ballast layer (4) and a residual recycling layer (7) situated under the same,
    b) the upper ballast layer (4) is cleaned, thus producing ballast (9) and spoil (10),
    c) usable spoil (10) is discharged upon an exposed earth formation (11) and graded and compacted to form an intermediate layer (14),
    d) to create a formation protection layer (19), new gravel (17) is discharged upon the intermediate layer (17) and graded and compacted,

    characterized in that the usable spoil (10) is supplemented by gravel (17).
  2. A method according to claim 1, characterized in that the usable spoil (10) is mixed with gravel (17), as needed, to maintain a constant height of the intermediate layer (14).
  3. A method according to claim 1, characterized in that the usable spoil (10) is mixed with gravel (17), as needed, for maintaining a constant quality of the intermediate layer (14), particularly with regard to optimal compactibility.
  4. A method according to one of claims 1 to 3, characterized in that the usable spoil (10) and the added gravel (17) is mixed with aggregate materials and subsequently discharged to form the intermediate layer (14).
  5. A method according to one of claims 1 to 4, characterized in that a fleece layer (15) is placed upon both the compacted intermediate layer (14) as well as the formation protection layer (19).
