Description

Die vorliegende Erfindung betrifft ein Verfahren zur Verbesserung oder Instandsetzung von Gleisanlagen mit einem Unterbau und einem Schotterbett als Oberbau mit den Schritten: Ausbauen des Schotters des Schotterbetts, Ausbauen des Materials des Unterbaus bis auf eine gewünschte Tiefe, erforderlichenfalls Herstellen eines neuen Erdplanums, Einbau eines neuen Unterbaus, Herstellen eines neuen Schotterbetts.The present invention relates to a method for improving or repairing track systems with a substructure and a ballast bed as a superstructure comprising the steps of: removing the ballast of the ballast bed, removing the material of the substructure to a desired depth, if necessary producing a new Erdplanums, installation of a new Substructure, making a new ballast bed.

Darüber hinaus betrifft die vorliegende Erfindung eine Vorrichtung zur Verbesserung oder Instandsetzung von Gleisanlagen mit einem Unterbau und einem Schotterbett als Oberbau mit einer ersten Aushubeinrichtung, insbesondere Aushubkette, zum Ausbauen des Schotters, einer zweiten Aushubeinrichtung, insbesondere Aushubkette, zum Ausbauen von Unterbaumaterial, erforderlichenfalls einer Einrichtung zum Herstellen eines neuen Erdplanums, einer Einrichtung zum Einbauen eines neuen Unterbaus und einer Einrichtung zum Herstellen eines neuen Schotterbetts.Moreover, the present invention relates to a device for improving or repairing track systems with a substructure and a ballast bed as a superstructure with a first excavating device, in particular Aushubkette, for removing the ballast, a second excavating device, in particular Aushubkette, for removing substructure material, if necessary, a device for producing a new earth bank, means for installing a new substructure and means for producing a new ballast bed.

Bei bisher bekannten Verfahren wird zwar der Schotter teilweise wiederverwendet, das ausgebaute Material des Unterbaus wird jedoch abtransportiert und entsorgt. Der neue Unterbau wird mit Neumaterial hergestellt. Neben dem aufwändigen Transport des ausgebauten Altmaterials und des eingebauten Neumaterials, der überwiegend mit Lastkraftwagen durchgeführt wird, ist die Deponierung des Altmaterials teuer, da es sich zumindest teilweise um schadstoffbelastetes Material handelt. Die Verwendung von Neumaterial führt zudem zu Landschaftsverbrauch.In previously known methods, although the gravel is partially reused, the removed material of the substructure is, however, transported away and disposed of. The new substructure is made with new material. In addition to the complex transport of the old material removed and the installed new material, which is carried out predominantly by trucks, the landfill of the old material is expensive, since it is at least partially polluted material. The use of new material also leads to landscape consumption.

Die Aufbereitung des ausgebauten Schotters zur Wiederverwendung erfolgt bei bekannten Verfahren und Vorrichtungen durch Siebanlagen, also durch Trennung der Schotteranteile in Abhängigkeit der Körnung. Insbesondere wird Schotter mit einer Körnung > 30 mm wiederverwendet, während Schotter mit kleinerer Körnung und sonstige Rückstände nicht wiederverwendet werden. Der wiederverwendete Schotter mit Körnung > 30 mm wird zumindest teilweise aufbereitet, beispielsweise mittels Prallbrecher und Reinigung in einer Waschanlage.The processing of the removed ballast for reuse is carried out in known methods and devices by screening plants, ie by separation of the gravel shares depending on the grain size. In particular, gravel with a grain size> 30 mm is reused, while gravel with smaller grain size and other residues are not reused. The reused gravel with grain size> 30 mm is at least partially processed, for example by means of impact crusher and cleaning in a car wash.

Ein Verfahren gemäß dem Oberbegriff von Anspruch 1 und eine Vorrichtung gemäß dem Oberbegriff von Anspruch 9 sind aus EP 1 939 355 A bekannt. Weiterer relevanter Stand der Technik ist in EP 0 629 744 A enthalten. EP 2 025 810 A1 stellt Stand der Technik nach Artikel 54(3) EPÜ dar.A method according to the preamble of claim 1 and an apparatus according to the preamble of claim 9 are made EP 1 939 355 A known. Further relevant prior art is in EP 0 629 744 A contain. EP 2 025 810 A1 represents prior art under Article 54 (3) EPC.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art anzugeben, die weniger Kosten und weniger Landschaftsverbrauch verursachen.The invention has for its object to provide a method and an apparatus of the type mentioned, which cause less cost and less landscape consumption.

Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art durch die Merkmale von Anspruch 1 gelöst.This object is achieved in a method of the type mentioned by the features of claim 1.

Bei einer Vorrichtung der eingangs genannten Art wird diese Aufgabe durch die Merkmale von Anspruch 9 gelöst.In a device of the type mentioned, this object is solved by the features of claim 9.

Durch den separaten Ausbau von Material aus der genannten Mischzone und dem Einbauen des Mischzonenmaterials als Teil des neuen Unterbaus ergibt sich zum einen der Vorteil, dass weniger Altermaterial ab transportiert und entsorgt werden muss, und zum anderen, dass weniger Neumaterial für den Aufbau des neuen Unterbaus benötigt wird. Neben den verringerten Transport- und Entsorgungskosten verringert sich dadurch auch der Landschaftsverbrauch.Due to the separate removal of material from said mixing zone and the incorporation of the mixed zone material as part of the new substructure results on the one hand the advantage that less aging material must be transported and disposed of, and on the other, that less new material for the construction of the new substructure is needed. Next The reduced transport and disposal costs also reduce the landscape consumption.

Das ausgebaute Mischzonenmaterial wird direkt auf den verbleibenden Unterbau oder das neue Erdplanum abgelegt und dort eingebaut, insbesondere als Tragschicht. Der Aus- und Wiedereinbau des Mischzonenmaterials kann dadurch besonders einfach erfolgen.The developed mixed zone material is deposited directly on the remaining substructure or the new Erdplanum and installed there, in particular as a base course. The removal and replacement of the mixing zone material can be done very easily.

Bevorzugt wird das Mischzonenmaterial unverändert wieder eingebaut. Das Mischzonenmaterial ist oft für den Wiedereinbau bereits gebrauchsfertig. Dies kann besonders dadurch gefördert werden, dass die Höhe der auszubauenden Zwischenschicht nach einer Ausgestaltung der Erfindung in Abhängigkeit der Ergebnisse einer vorab durchgeführten Bodenuntersuchung festgelegt wird. Aufwändige Reinigungs- oder Aufbereitungsarbeiten können dadurch entfallen.The mixing zone material is preferably reinstalled unchanged. The mixed zone material is often ready for replacement. This can be particularly promoted by the fact that the height of the intermediate layer to be removed according to an embodiment of the invention is determined depending on the results of a previously carried out soil examination. Elaborate cleaning or treatment work can be omitted.

Nach einer weiteren Ausgestaltung der Erfindung wird der ausgebaute Schotter zumindest teilweise aufbereitet und wieder eingebaut. In an sich bekannter Weise können dadurch die Kosten und die Menge abzutransportierenden und zu entsorgenden Materials verringert werden.According to a further embodiment of the invention, the excavated ballast is at least partially processed and reinstalled. In a manner known per se, the costs and the amount of material to be removed and disposed of can thereby be reduced.

Bei einer solchen Wiederaufbereitung des Schotters ist es vorteilhaft, wenn mindestens ein Teil der Aufbereitungsrückstände des Schotters ebenfalls wieder eingebaut werden. Die Aufbereitungsrückstände werden dabei bevorzugt auf das wiedereingebaute Mischzonenmaterial aufgebracht und besonders bevorzugt mit diesem vermischt. Neben dem Mischzonenmaterial kann dadurch eine weitere Materialmenge aus der alten Gleisanlage für die neue Gleisanlage wiederverwendet werden. Die Kosten und die bereits erwähnten Transport- und Deponieleistungen können dadurch weiter reduziert werden. Durch die Vermischung der Aufbereitungsrückstände mit dem Mischzonenmaterial ergibt sich eine gute Beschaffenheit der eingebauten Schicht, die insbesondere als Planumsschutzschicht oder Frostschutzschicht dienen kann.In such a reprocessing of the ballast, it is advantageous if at least a portion of the processing residues of the ballast are also reinstalled. The treatment residues are preferably applied to the reincorporated mixed zone material and more preferably mixed with this. In addition to the mixing zone material can be reused a further amount of material from the old track system for the new track system. The costs and the already mentioned transport and landfill services can thereby be further reduced. The mixing of the treatment residues with the mixed zone material results in a good quality of the built-in layer, which can serve in particular as a layer protection layer or antifreeze layer.

Dem wiedereingebauten Mischzonenmaterial können auch Zusatzstoffe in flüssiger und/oder fester Form, insbesondere pulverisierter Form beigefügt werden. Dadurch können die Eigenschaften des wieder eingebauten Mischzonenmaterials ebenfalls verbessert werden.The rebuilt mixed zone material also additives in liquid and / or solid form, in particular powdered form can be added. As a result, the properties of the rebuilt mixed zone material can also be improved.

Die nach der jeweiligen Bodenbeschaffenheit und dem Bodengutachten erforderliche Gesamtstärke des neuen Unterbaus wird insbesondere durch Zuführung, Einbau und Verdichtung von Neumaterial erreicht. Der neue Unterbau kann dabei ein- oder mehrlagig, insbesondere zweilagig aufgebaut sein, um insbesondere bei großer Gesamtstärke eine ausreichende Verdichtung zu ermöglichen.The total thickness of the new substructure required according to the respective soil condition and the soil assessment is achieved in particular by feeding, installation and compaction of new material. The new substructure can be constructed in one or more layers, in particular two-layered, in order to allow sufficient compression in particular with large overall thickness.

Das ausgebaute Material des Unterbaus wird gemäß einer Ausgestaltung der Erfindung insbesondere vollständig abtransportiert und entsorgt. Das Material ist in der Regel für den Wiedereinbau nicht geeignet. Durch die entsprechende Zuführung von Neumaterial kann daher eine gute Qualität des neuen Unterbaus erreicht werden.The removed material of the substructure is in particular completely removed and disposed of according to an embodiment of the invention. The material is usually not suitable for reinstallation. By the appropriate supply of new material, therefore, a good quality of the new substructure can be achieved.

Das eingebaute Material, insbesondere das Mischzonenmaterial und/oder die Aufbereitungsrückstände und/oder das neue Unterbaumaterial werden bevorzugt planiert und/oder verdichtet. Dadurch kann die Qualität der jeweiligen Schicht erhöht werden.The incorporated material, in particular the mixing zone material and / or the treatment residues and / or the new substructure material, are preferably leveled and / or compacted. As a result, the quality of the respective layer can be increased.

Nach einer Ausgestaltung der Erfindung werden mindestens ein Teil, bevorzugt jedoch alle Verfahrensschritte bei vorhandenem Gleisgestänge durchgeführt. Ein Entfernen des Gleisgestänges entfällt dadurch. Auch kann der An- und Abtransport der Materialien vorteilhaft über das Gleis erfolgen. Die Kosten und eine Beeinträchtigung eines möglichen Nachbargleises können dadurch reduziert werden.According to one embodiment of the invention, at least a part, but preferably all process steps are carried out with existing track linkage. Removal of the track linkage is thereby eliminated. Also, the supply and removal of the materials can advantageously be done via the track. The costs and an impairment of a possible neighboring track can be reduced.

Mit der dritten Aushubeinrichtung der erfindungsgemäßen Vorrichtung kann das Material aus der Mischzone ausgebaut werden. Hierfür kann eine Aushubkette vorgesehen sein, wie sie auch für den Ausbau des Schotters und des Unterbaumaterials verwendet wird. Erfindungsgemäss ist die Verwendung eines Schneidblechs zum Ausbau des Mischzonenmaterials vorgesehen. Dieses kann insbesondere oberhalb der Aushubkette für das Material des Unterbaus angeordnet sein. Mit einem solchen Schneidblech ist es vorteilhaft möglich, das ausgebaute Mischzonenmaterial direkt auf den verbleibenden Unterbau oder das neue Erdplanum abzulegen. Eine separate Fördereinrichtung ist hierfür nicht erforderlich. Besonders bevorzugt ist das Schneidblech steuerbar, um die Höhe der ausgebauten Mischzone einzustellen.With the third excavation device of the device according to the invention, the material can be removed from the mixing zone. For this purpose, a Aushubkette be provided, as it is also used for the expansion of the ballast and the substructure material. According to the invention, the use of a cutting plate for removing the mixed zone material is provided. This can be arranged in particular above the Aushubkette for the material of the substructure. With such a cutting plate, it is advantageously possible to store the developed mixed zone material directly on the remaining substructure or the new Erdplanum. A separate conveyor is not required for this purpose. Particularly preferably, the cutting plate is controllable to adjust the height of the developed mixing zone.

Eine Einrichtung zur Aufbereitung des Schotters und eine Fördereinrichtung zum Fördern des aufbereiteten Schotters zur Schottereinbaueinrichtung können insbesondere in herkömmlicher Weise ausgebildet sein. Eine entsprechende Förder- und Einbaueinrichtung dient bevorzugt zum Fördern und Einbauen mindestens eines Teils der Aufbereitungsrückstände auf dem wiedereingebauten Mischzonenmaterial.A device for processing the ballast and a conveying device for conveying the processed ballast to the bulkhead installation device can be designed in particular in a conventional manner. A corresponding conveying and installation device is preferably used for conveying and installing at least a portion of the treatment residues on the rebuilt mixed zone material.

Weiter bevorzugt ist eine Mischeinrichtung zum Mischen der Aufbereitungsrückstände mit dem Mischzonenmaterial vorgesehen, insbesondere eine Egge oder Stachelwalze. Dadurch kann die Eigenschaft dieser Schicht aus wiedereingebautem Material verbessert werden. Eine weitere Verbesserung kann sich durch die Zugabe von Zusatzstoffen fester oder flüssiger Form, insbesondere pulverisierter Form ergeben, für die entsprechende Mittel in der Vorrichtung vorgesehen sind.More preferably, a mixing device for mixing the treatment residues with the mixing zone material is provided, in particular a harrow or spiked roller. This may be the property of this layer be improved from rebuilt material. A further improvement may result from the addition of additives of solid or liquid form, in particular pulverized form, for which corresponding agents are provided in the device.

Das Zuführen von neuem Material zur Einbaueinrichtung für den Unterbau erfolgt über eine Zufuhreinrichtung, die ebenfalls in herkömmlicher Weise ausgebildet sein kann. Auch die Abfuhreinrichtung für das ausgebaute Unterbaumaterial kann in herkömmlicher Weise aufgebaut sein.The feeding of new material to the installation device for the substructure via a supply device, which may also be formed in a conventional manner. The discharge device for the removed substructure material can also be constructed in a conventional manner.

Weiter umfasst die Vorrichtung bevorzugt einen Verdichter und/oder eine Planiereinrichtung, insbesondere ein Planierschild. Mit diesem können die verschiedenen Schichten verdichtet und planiert werden.Furthermore, the device preferably comprises a compressor and / or a leveling device, in particular a dozer blade.

Im unteren Bereich von Fig. 1 ist ein Gleis 1 mit Schienen 2 und Schwellen 3 dargestellt, wobei jedoch nur eine Schiene 2 zu sehen ist Im linken unteren Bereich ist die alte, zu erneuernde Gleisanlage dargestellt, und im rechten unteren Bereich die gemäß der Erfindung hergestellte neue Gleisanlage.In the lower part of Fig. 1 is a track 1 with rails 2 and 3 thresholds shown, but only one rail 2 can be seen in the lower left area, the old, to be renewed track system is shown, and in the right lower area the new track system produced according to the invention.

Die alte Gleisanlage umfasst eine Schotterschicht 4, in welche das Gleis 1 eingebettet ist. Unterhalb der Schotterschicht 4 befindet sich der Unterbau 5. Im Übergangsbereich zwischen der Schotterschicht 4 und dem Unterbau 5 befindet sich eine Mischzone 6, deren Stärke insbesondere durch eine Bodenuntersuchung vorab bestimmt wird. Die Mischzone 6 besteht dabei insbesondere aus zerkleinertem Schotter bzw. Schotterabrieb und Material des alten Unterbaus. Die Stärke der Mischzone kann beispielsweise 10 cm betragen.The old track system comprises a ballast layer 4, in which the track 1 is embedded. Below the ballast layer 4 is the substructure 5. In the transition region between the ballast layer 4 and the substructure 5 is a mixing zone 6, the strength of which is determined in advance by a soil examination in particular. The mixing zone 6 consists in particular of crushed ballast or gravel abrasion and material of the old substructure. The strength of the mixing zone can be, for example, 10 cm.

Der Altschotter der Schotterschicht 4 wird mittels einer Aufnahmekette bekannter Bauart ausgebaut, die hier nicht dargestellt ist. Üblicherweise weist eine solche Aushubkette Kratzerfinger und einen Aufnahmebalken zum Transport des ausgebauten Materials auf. Das Material der Mischzone 6 kann ebenfalls mit einer solchen Aushubkette ausgebaut werden. Bevorzugt ist die Verwendung eines Schneidbleches 12, welches entsprechend der auszubauenden Stärke der Mischzone 6 einstellbar ist. Mit einer dritten Aufnahmekette wird das Material des Unterbaus 5 bis auf eine gewünschte Tiefe ausgebaut.The old ballast of the ballast layer 4 is removed by means of a receiving chain known type, which is not shown here.

Hierfür sind Eggen oder Stachelwalzen 13 vorgesehen. Die aufgebrachte Schicht aus Aufbereitungsrückständen ist mit 9 gekennzeichnet.The removed material of the substructure 5 is removed via the track 1, optionally transferred to trucks and disposed of in landfills. The removed material of the mixing zone 6 is applied directly and preferably untreated to the remaining substructure or a newly created Erdplanum 7 and forms there a layer 8.
