Description

Schienenfahrzeug zur Gleisunterbausanierung Rail vehicle for track underbody restoration
Die vorliegende Erfindung betrifft ein Schienenfahrzeug zur Gleisunterbausanierung, welches aufweist: eine Gleishebeeinrichtung zum vorübergehenden Ausheben des Gleises aus seinem Gleisbett in einem Arbeitsbereich, eine Gleisbett-Räumeinrichtung zum Abräumen des Gleisbetts im Arbeitsbereich, eine Unterbau-Räumeinrichtung zum Abräumen des darunter- liegenden Unterbaus im Arbeitsbereich bis zu einer vorgegebenen Tiefe hinab, eine Unterbau-Aufbringeinrichtung zum Aufbringen von neuem Unterbau im Arbeitsbereich, und eine Gleisbett-Aufbringeinrichtung zum Aufbringen von neu- em Gleisbett im Arbeitsbereich, wobei das Schienenfahrzeug eine Unterbau-Rezyklierein- richtung aufweist, welche zumindest einen Teil des Abraums der Unterbau-Räumeinrichtung in die Unterbau-Aufbringeinrichtung einspeist. Ein Schienenfahrzeug dieser Art ist aus der EP 1 643 035 A2 bekannt. Dabei werden sowohl das Gleisbett als auch die Planumsschutzschicht (PSS) jeweils gesondert rezykliert, d.h. der Schotterabraum zu Neuschotter und der PSS-Abraum zu Neu-PPS. Der sanierte Gleisunterbau besteht dadurch vollständig aus Re- zyklat, was in der Praxis zu einer mangelhaften Qualität der Sanierung führt, da PSS-Material genau definierte Festigkeitseigenschaften 'haben muß.The present invention relates to a railway track renewal rail vehicle comprising: a track lifter for temporarily lifting the track from its track bed in a work area, a track bed clearing device for clearing the track bed in the work area, a floor clearing device for clearing the underlying deck in the work area down to a predetermined depth, a subgrade application device for applying new substructure in the working area, and a track bed application device for applying a new track bed in the work area, wherein the rail vehicle has a substructure recycling device, which at least part of the Abraums the substructure clearing device fed into the substructure applicator. A rail vehicle of this type is known from EP 1 643 035 A2. In this case, both the track bed and the layer protection layer (PSS) are each recycled separately, i. the gravel overburden to Neuschotter and the PSS overburden to new PPS. The rehabilitated track substructure consists entirely of recycled material, which in practice leads to a poor quality of the refurbishment, since PSS material must have precisely defined strength properties.
Aus der EP 0 790 352 A2 ist eine Gleisunterbausanierungs- maschine bekannt, bei welcher der obere Teil des Schotterbetts abgeräumt, zerkleinert, mit Sand vermischt und als neue Planumsschutzschicht verwendet wird.From EP 0 790 352 A2, a track sub-base reorganization machine is known in which the upper part of the ballast bed is cleared, crushed, mixed with sand and used as a new level protective layer.
Ein anderes Gleisunterbausanierungsfahrzeug ist in der Zeitschrift „ETR - Eisenbahntechnische Rundschau", Heft 4/2004, Seiten 225 bis 228, beschrieben und unter der Typenbezeichnung PM 200-2R bekannt. Die Maschine PM 200-2R ermöglicht in einem kontinuierlichen Arbeitsvorgang sowohl das Austauschen des Gleisbettmaterials als auch des Unterbaumaterials, wobei zwar eine Rezykliereinrichtung für das Gleisbettmaterial vorgesehen ist, der Abraum der Unterbau-Räumeinrichtung jedoch zur Gänze abgeführt wird, was eine kostspielige Entsorgung und das Aufbringen von teurem Neu-PSS-Material erfordert.Another track underbody repair vehicle is described in the journal "ETR - Eisenbahntechnische Rundschau", issue 4/2004, pages 225 to 228, and known under the type designation PM 200-2 R. The machine PM 200-2R allows in one continuous operation both the replacement of the track bed material and the substructure material, although a recycler for the track bed material is provided, the overburden of the sub-base clearing device is, however, completely dissipated, which requires costly disposal and the application of expensive new PSS material.
Die Erfindung setzt sich zum Ziel, ein Schienenfahrzeug zur Gleisunterbausanierung zu schaffen, welches einen wirtschaftlicheren Betrieb ermöglicht als die bekannten Lösungen, ohne Abstriche in Bezug auf die Qualität der Sanierung und Arbeitsgeschwindigkeit des Fahrzeugs hinnehmen zu müssen.The invention has for its object to provide a rail vehicle for track substructure renovation, which allows a more economical operation than the known solutions, without having to accept reductions in the quality of the refurbishment and operating speed of the vehicle.
Dieses Ziel wird mit einem Schienenfahrzeug der einleitend genannten Art erreicht, das sich erfindungsgemäß dadurch auszeichnet, daß die Unterbau-Räumeinrichtung zumindest in eine erste Räumeinheit zum Abräumen einer oberen Schicht des Unterbaus und eine nachgeordnete zweite Räumeinheit zum Abräumen einer unteren Schicht des Unterbaus unterteilt ist, daß die Unterbau-Aufbringeinrichtung zumindest in eine er- ste Aufbringeinheit zum Aufbringen einer ersten Unterbauschicht und eine nachgeordnete zweite Aufbringeinheit zum Aufbringen einer darüberliegenden zweiten Unterbauschicht unterteilt ist, und daß die Unterbau-Rezykliereinrichtung den Abraum aus der ersten Räumeinheit als Material für die erste Unterbauschicht in die erste Aufbringeinheit einspeist.This object is achieved with a rail vehicle of the aforementioned type, which according to the invention is characterized in that the substructure clearing device is divided into at least a first clearing unit for clearing an upper layer of the substructure and a downstream second clearing unit for clearing a lower layer of the substructure, in that the substructure application device is subdivided into at least a first application unit for applying a first substructure layer and a subordinate second application unit for applying an overlying second substructure layer, and in that the substructure recycling device uses the overburden from the first clearing unit as material for the first subgrade layer feeds the first application unit.
Auf diese Weise wird das Gleisunterbaumaterial in zwei aufeinanderfolgenden Stufen abgebaut und der Abraum der ersten Stufe als Tragschicht für darüber aufgefülltes neues Unterbau- material verwendet, und dies in einem kontinuierlichen Betrieb während der Fahrt. Die Erfindung beruht auf der Erkenntnis, daß ein solcher Unterbau-Zweischichtaufbau aus rezykliertem Material und Neumaterial ohne jedwede Abstriche in der Gesamtfestigkeit und Qualität des Gleisunterbaus eine beträchtliche Ein- sparung an entsorgungspflichtigem Abraum und zuzukaufendem Neu- material ermöglicht. In Summe wird damit ein wesentlich wirtschaftlicherer Betrieb der Unterbausanierungsmaschine erreicht als mit den bekannten Konstruktionen.In this way, the track substructure material is degraded in two successive stages, and the first stage overburden is used as the base for overfilled new subgrade material, and this in continuous operation while in motion. The invention is based on the recognition that such a substructure-two-layer structure made of recycled material and virgin material without any compromise in the overall strength and quality of the track substructure, a considerable saving in waste material to be disposed of and to buy new material allows. In sum, a much more economical operation of the Unterbausanierungsmaschine is achieved than with the known constructions.
Dem Fachmann ist klar, daß in der Praxis keine exakte Ab- grenzung zwischen dem Gleisbett und seinem Unterbau vorliegt, da loses Material, z.B. Schotter, Absplitterungen, Abrieb usw. des Gleisbetts in den Unterbau diffundieren kann und/oder sich seitlich vom Gleis ausbreiten oder - z.B. bei einem Damm - an den Flanken des Unterbaus herabrieseln kann. Der hier verwende- te Begriff „obere Schicht des Unterbaus" umfaßt demzufolge auch eine allfällige Mischzone, in welcher Gleisbettmaterial parasitär von oben in den Unterbau eingedrungen ist, sich seitlich ausgebreitet hat oder an den Flanken des Unterbaus böschungsartig vorliegt. Gemäß einer bevorzugten Ausführungsform der Erfindung weist die Unterbau-Rezykliereinrichtung einen Mischer zum Einbringen von Zusatzstoffen in den Abraum auf. Mit Hilfe solcher Zusatzstoffe können die Eigenschaften des rezyklierten Abraums definiert eingestellt werden. Bevorzugt weist die Unterbau-Rezykliereinrichtung ferner eine Einrichtung zum Zerkleinern des Abraums, einen Magnetabscheider zum Entfernen von Metall aus dem Abraum und/oder ein Sieb zum Abscheiden von Feingut aus dem Abraum auf, um die Qualität des rezyklierten Unterbaumaterials je nach Anforderung weiter zu verbessern.It is clear to the person skilled in the art that in practice there is no exact demarcation between the track bed and its substructure since loose material, e.g. Gravel, chipping, abrasion, etc. of the track bed can diffuse into the substructure and / or spread laterally from the track or -. at a dam - can trickle down on the flanks of the substructure. The term "upper layer of the substructure" as used herein accordingly also encompasses a possible mixing zone in which trackbed material has penetrated parasitically from above into the substructure, has spread laterally or is resembling a slope on the flanks of the substructure With the aid of such additives, the properties of the recycled overburden can be set in a defined manner Preferably, the substructure recycling device also has a device for comminuting the overburden, a magnetic separator for removing metal from the overburden and / or a screen for separating fines from the overburden in order to further improve the quality of the recycled substructure material as required.
Besonders günstig ist es, wenn die erste und die zweite Räumeinheit jeweils durch eine eigene Räumkette gebildet sind. Mit Hilfe derartiger Räumketten können sowohl die Räumtiefe als auch -breite einfach variiert und individuell an den Bahnkörper angepaßt werden.It is particularly favorable when the first and the second clearing unit are each formed by their own clearing chain. With the help of such Räumketten both the clearance depth and width can be easily varied and adapted individually to the railway body.
Gemäß einer weiteren vorteilhaften Variante der Erfindung beträgt die Abräumtiefe der ersten Räumeinheit und die Aufbringhöhe der ersten Aufbringeinheit jeweils 10 bis 25 cm, bevorzugt 15 bis 20 cm; besonders bevorzugt beträgt die Abräum- tiefe der zweiten Räumeinheit 10 bis 65 cm. Die dadurch er- reichten Schichtdicken ergeben eine Maximierung des Rezyklie- rungsanteiles im Unterbau ohne Beeinträchtigung seiner Tragfähigkeit und Dauerhaftigkeit.According to a further advantageous variant of the invention, the first Abräumtiefe reamer and the Aufbringhöhe the first application unit is in each case 10 to 25 cm, preferably 15 to 20 cm; Particularly preferably, the clearing depth of the second clearing unit is 10 to 65 cm. The resulting layer thicknesses result in a maximization of the proportion of recy- cling in the substructure without adversely affecting its load bearing capacity and durability.
Besonders vorteilhaft ist es, wenn das Schienenfahrzeug eine Siloeinheit aufweist, welche neues ünterbaumaterial bevorratet und als- Material für die zweite Unterbauschicht in die zweite Aufbringeinheit einspeist, um kontinuierlich eine hohe Qualität des Unterbaus zu erzielen.It is particularly advantageous if the rail vehicle has a silo unit which stores new cementitious material and feeds material for the second underground construction layer into the second application unit in order to continuously achieve a high quality of the substructure.
Gemäß einer weiteren vorteilhaften Ausführungsform der Er- findung wird vorgesehen, daß die Gleishebeeinrichtung in eine erste Gleishebeeinheit zum vorübergehenden Ausheben des Gleises aus seinem Gleisbett in einem ersten Abschnitt des Arbeitsbereichs und in eine zweite Gleishebeeinheit zum nochmaligen vorübergehenden Anheben des Gleises in einem davon beab- standeten zweiten Abschnitt des Arbeitsbereichs unterteilt ist, wobei die Gleisbett-Räumeinrichtung und die erste Räumeinheit im genannten ersten Abschnitt des Arbeitsbereiches arbeiten und die zweite Räumeinheit, die Unterbau-Aufbringeinrichtung und die Gleisbett-Aufbringeinrichtung im genannten zweiten Ab- schnitt des Arbeitsbereiches arbeiten, und wobei sich das Schienenfahrzeug mit zumindest einem seiner Fahrgestelle im Bereich zwischen dem ersten und dem zweiten Abschnitt auf dem vorübergehend auf der unteren Unterbauschicht zur Auflagerung kommenden Gleis abstützt. Durch die Aufteilung des Arbeitsbe- reiches in zwei aufeinanderfolgende Abschnitte, zwischen denen sich das Schienenfahrzeug abstützen kann, wird das Gewicht des Schienenfahrzeugs besser verteilt und sein maximales Achsgewicht reduziert, was für den Einsatz auf Brücken, speziellen Untergründen usw. von entscheidender Bedeutung ist. Darüber hinaus ermöglicht die Aufteilung in zwei Arbeitsabschnitte eine Gelenkkupplung zwischen den Abschnitten, so daß auch enge Kürvenradien befahren werden können.According to a further advantageous embodiment of the invention it is provided that the track lifting device in a first track lifting unit for temporarily lifting the track from its track bed in a first portion of the work area and in a second track lifting unit for repeated temporary lifting of the track in one of them spaced the second section of the work area and the second clearing unit, the subgrade applying device and the track bed applying device operate in said second portion of the work area, and wherein the rail vehicle is supported with at least one of its chassis in the area between the first and the second section on the temporary on the lower layer of substructure for suspension coming track. Dividing the work area into two consecutive sections that support the rail vehicle helps to better distribute the weight of the rail vehicle and reduce its maximum axle weight, which is critical for use on bridges, special undergrounds, etc. In addition, the division into two working sections allows a joint between the sections, so that even narrow Kürvenradien can be traveled.
Besonders günstig ist es, wenn das Schienenfahrzeug, wie an sich bekannt, auch eine Gleisbett-Rezykliereinrichtung auf- weist, welche den Abraum aus der Gleisbett-Räumeinrichtung, ge- gebenenfalls zusammen mit neuem Gleisbettmaterial aus einer mitgeführten Siloeinheit, in die Gleisbett-Aufbringeinrichtung einspeist .It is particularly favorable if, as is known per se, the rail vehicle also has a track-bed recycling device which removes the overburden from the track-bed clearing device. if necessary together with new track bed material from a carried silo unit, feeds into the track bed applicator.

Anhand von Fig. 1 werden die Hauptkomponenten und die Funktionsweise des Schienenfahrzeugs der Erfindung nun im Überblick erläutert. Fig. 1 zeigt schematisch ein Schienenfahrzeug 2.0 1, das zur kontinuierlichen Sanierung eines auf einem Untergrund 2 aufliegenden Gleisunterbaus 3 für ein Gleis 4 in einem Gleisbett 5 dient, d.h. zur Gleisunterbausanierung während der Fahrt des Schienenfahrzeugs 1 in Fahrtrichtung 6. Das Schienenfahrzeug 1 kann dazu über einen eigenen Antrieb verfügen oder 25 von einer Lokomotive angetrieben sein.With reference to Fig. 1, the main components and the operation of the rail vehicle of the invention will now be explained in overview. Fig. 1 shows schematically a rail vehicle 2.0 1, which serves for the continuous rehabilitation of a resting on a substrate 2 track base 3 for a track 4 in a track bed 5, i. for track substructure renovation during the journey of the rail vehicle 1 in the direction of travel 6. The rail vehicle 1 may have its own drive or be 25 driven by a locomotive.
Das Gleisbett 5 ist üblicherweise eine Schotterbettung, in welche das Schienen 7 und Schwellen 8 umfassende Gleis 4 teilweise eingebettet ist; alternativ könnte das Gleisbett 5 auch beliebiger anderer Art sein, wie dem Fachmann bekannt. 30 Der zu sanierende -Unterbau 3 kann sich aus Erdmaterial, aber auch aus bereits früher einmal saniertem Unterbau (z.B. altem PSS-Material) zusammensetzen. Wie eingangs erwähnt, umfaßt der hier verwendete Begriff „Unterbau" auch jene Mischzone des Unterbaus 3, in welcher loses Gleisbettmaterial, z.B. 35 Schotter, Absplitterungen, Abrieb usw. von oben in das Erdmate- rial (oder altes PSS-Material) des ünterbaus eingedrungen ist, sich auf diesem neben dem Gleis bzw. ursprünglichen Gleisbett 5 seitlich ausgebreitet (verbreitert) hat und/oder - bei einem Dammaufbau - an den Flanken des Unterbaus 3 herabgerieselt ist und böschungsartig anliegt, wie dem Fachmann bekannt. In der Praxis kann bis zu 30 - 40 % des ursprünglichen (d.h. bei einem neuen Bahnkörper aufgebrachten) Gleisschotters in dieser Mischzone des ünterbaus 3 vorliegen.The track bed 5 is usually a ballast bed, in which the track 7 and 8 thresholds comprehensive track 4 is partially embedded; Alternatively, the track bed 5 could also be of any other type, as known in the art. 30 The substructure 3 to be rehabilitated can be composed of earth material, but also of substructures that have already been rehabilitated (eg old PSS material). As mentioned above, the term "substructure" as used herein also includes that mixing zone of the substructure 3, in which loose track bed material, eg 35 gravel, chipping, abrasion, etc. from above into the earth mate- rial (or old PSS material) of the ünterbaus has penetrated, laterally spread (widened) on this next to the track or original track bed 5 and / or - in a dam construction - is down on the flanks of the base 3 and böschungsartig rests, as known in the art. In practice, up to 30-40% of the original track ballast (ie applied to a new track body) may be present in this mixing zone of the substructure 3.
Das Schienenfahrzeug 1 ist mit einer Gleishebeeinrichtung 9 zum vorübergehenden, d.h. während der Fahrt fortschreitendem Ausheben des Gleises 4 aus seinem Gleisbett 5 in einem Arbeitsbereich 10 ausgestattet. Im Arbeitsbereich 10 erfolgt ein Abräumen des Gleisbetts 5 mit Hilfe einer Gleisbett-Räumeinrichtung 11 und anschließend ein Abräumen des Unterbaus 3 mit- tels einer Unterbau-Räumeinrichtung 12, 13. Dann werden ein neuer Unterbau 3' durch eine Unterbau-Aufbringeinrichtung 15, 16 und darüber ein neues Gleisbett 5' durch eine Gleisbett- Aufbringeinrichtung 17 aufgebracht, wobei gleichzeitig das Gleis 4 wieder i.n das neue Gleisbett 5' abgelegt wird. Die Gleisbett-Aufbringeinrichtung 17 kann in dem Fachmann bekannter Weise auch eine oder mehrere Stopfeinheiten (nicht gezeigt) zum Verfüllen des Gleisbettmaterials unter und zwischen die Schwellen 8 bzw. Schienen 7 des Gleises 4 aufweisen.The rail vehicle 1 is provided with a track lifting device 9 for temporary, i. while traveling progressively digging the track 4 from its track bed 5 in a workspace 10 equipped. In the working area 10, the track bed 5 is cleared by means of a track bed clearing device 11 and then cleared of the substructure 3 by means of a substructure clearing device 12, 13. Then, a new substructure 3 'by a substructure application device 15, 16 and about a new track bed 5 'applied by a track bed applicator 17, at the same time the track 4 is again stored in the new track bed 5'. The track bed applier 17 may also include one or more dunnage units (not shown) for filling the track bed material below and between the sleepers 8 and rails 7 of the track 4, as known in the art.
Die Unterbett-Räumeinrichtung 12, 13 umfaßt eine erste Räumeinheit 12 zum Abräumen einer ersten oberen Schicht 18 des Unterbaus 3 und eine davon gesonderte, nachgeordnete zweite Räumeinheit 13 zum Abräumen einer unteren Schicht 19 des Unterbaus 3 bis zu einer vorgegebenen Tiefe oder auch bis ganz zum Untergrundplanum 14 des Untergrundes 2 hinab. In analoger Weise ist die Unterbau-Aufbringeinrichtung 15, 16 in eine erste Aufbringeinheit 15 zum Aufbringen einer ersten Unterbauschicht 20 (sog. „Tragschicht") und eine nachgeordnete zweite Aufbringeinheit- 16 zum Aufbringen einer darüberliegenden zweiten Unterbauschicht 21 (sog. „PSS-Schicht") unterteilt. Die obere Schicht 18 enthält auch die Mischzone zwischen dem Gleisbett 5 und dem Unterbau 3, in welcher ursprüngliches Gleisbettmaterial parasitär, wie oben erörtert, enthalten ist. Zur Erfassung insbesondere auch parasitären Flankenmaterials aus der Mischzone ist die Räumbreite der ersten Räumeinheit 12, wie in Fig. 4a gezeigt, größer als jene der Gleisbett- Räumeinrichtung 11 ausgelegt.The sub-bed clearing device 12, 13 comprises a first clearing unit 12 for clearing a first upper layer 18 of the substructure 3 and a separate, second sub-clearing unit 13 for clearing a lower layer 19 of the substructure 3 to a predetermined depth or even to Substrate plan 14 of the underground 2 down. In an analogous manner, the substructure application device 15, 16 is in a first application unit 15 for applying a first substructure layer 20 (so-called "base layer") and a downstream second application unit 16 for applying an overlying second substructure layer 21 (so-called "PSS layer ") divided. The upper layer 18 also contains the mixing zone between the track bed 5 and the substructure 3 in which original track bed material is contained parasitically as discussed above. For detecting in particular also parasitic flank material from the mixing zone, the clearing width of the first clearing unit 12, as shown in Fig. 4a, designed to be larger than that of the track bed clearing device 11.
Wie in Fig. 1 schematisch gezeigt, weist das Schienenfahrzeug 1 eine Unterbau-Rezykliereinrichtung 22 auf, welche den Abraum 12' aus der ersten Räumeinheit 12, d.h. die abgebaute Schicht 18, als Material für die erste Unterbauschicht 20 in die erste Aufbringeinheit 15 einspeist (Pfad 22' ) , und zwar bevorzugt unter Einbringen von Zusatzstoffen 23 in den Abraum 12' . Hingegen wird der Abraum 13' aus der zweiten Räumeinheit 13, d.h. die abgebaute Schicht 19, entsorgt (Pfad 24), und als Material für die zweite Unterbauschicht 21 wird der zweiten Aufbringeinheit 16 neues Unterbaumaterial, z.B. „frisches" PSS- Material, das aus Sanden definierter Körnung und Zusammensetzung besteht, zugeführt (Pfad 25) . Bevorzugt besitzt die obere Schicht 18 eine Dicke, d.h. Abräumtiefe der Räumeinheit 12, von 10 bis 25 cm, besonders bevorzugt 15 bis 20 cm, und die untere Schicht 19 eine Dicke, d.h. Abräumtiefe der Räumeinheit 13, von 10 bis 65 cm. Da im wesentlichen die gesamte obere Schicht 18 zur ersten Unterbau- schicht 20 rezykliert wird, hat die erste Unterbauschicht 20 bevorzugt dieselbe Dicke wie die obere Schicht 18, u.zw. 10 bis 25 cm, besonders bevorzugt 15 bis 20 cm.As shown schematically in Fig. 1, the rail vehicle 1 comprises a sub-base recycler 22 which removes the spoil 12 'from the first broaching unit 12, i. the degraded layer 18, as material for the first sub-layer 20 in the first application unit 15 feeds (path 22 '), preferably with the introduction of additives 23 in the overburden 12'. On the other hand, the overburden 13 'from the second clearing unit 13, i. the degraded layer 19 is discarded (path 24), and as a material for the second sub-layer 21, the second application unit 16 is given new sub-base material, e.g. "Fresh" PSS material consisting of sands of defined grain size and composition is fed (path 25) Preferably, the upper layer 18 has a thickness, ie clearing depth of the clearing unit 12, of 10 to 25 cm, particularly preferably 15 to 20 cm, and the lower layer 19 has a thickness, ie clearance depth, of the clearing unit 13 of 10 to 65 cm. Since substantially all of the upper layer 18 is recycled to the first substructure layer 20, the first subbing layer 20 preferably has the same thickness as the upper layer 18 , preferably 10 to 25 cm, more preferably 15 to 20 cm.
Da die obere Schicht 18 auch die genannte allfällige Mischzone mit dem Gleisbett 5 umfaßt, kann der Abraum 12' in der Praxis bis zu 30 - 40 % an (ursprünglichem) Gleisbettmaterial enthalten, d.h. sich aus 60 - 70 % Erdmaterial oder altem PSS-Material und 30 - 40 % parasitärem (eindiffundiertem, , ausgebreitetem, herabgerieseltem usw.) Gleisbettmaterial, z.B. Gleisschotter-Absplitterungen und -Abrieb, zusammensetzen. Da- durch kann das aus dem Abraum 12' erzeugte Rezyklat 22' einen parasitären Mischanteil von bis zu 30 bis 40% an ursprünglichem Gleisbettmaterial aus eindiffundiertem Material, Flankenmaterial, Absplitterungen, Abrieb usw. enthalten, der somit in vorteilhafter Weise ebenfalls in die erste Unterbauschicht 20 („Tragschicht") rezykliert wird.Since the upper layer 18 also comprises said optional mixing zone with the track bed 5, the overburden 12 'may in practice contain up to 30-40% of (original) track bed material, ie 60-70% earth material or old PSS material and 30 - 40% parasitic (diffused, spread, fallen down, etc.) track bed material, eg track ball splintering and abrasion. As a result, the recyclate 22 'produced from the overburden 12' can have a contain parasitic mixing proportion of up to 30 to 40% of original track bed material from diffused material, flank material, chipping, abrasion, etc., which is thus also advantageously recycled into the first subgrade layer 20 ("base layer").
Schließlich ist das Schienenfahrzeug 1 in an sich bekannter Weise mit einer Gleisbett-Rezykliereinrichtung 26 ausgerüstet, welche den Abraum 11' aus der Gleisbett-Räumeinrichtung 11, gereinigt und gesiebt und soweit erforderlich ergänzt durch neues Gleisbettmaterial 27, in die Gleisbett-Aufbringeinrichtung 17 einspeist.Finally, the rail vehicle 1 is equipped in a manner known per se with a track bed recycler 26 which cleans and sieves the overburden 11 'from the track bed clearing device 11 and, if necessary, adds new track bed material 27 to the track bed applicator 17.
Das Schienenfahrzeug 1 besteht in der Regel aus mehreren zu einem Zug gekuppelten Wagen (auch wenn dies nicht zwingend ist) und die in Fig. 1 gezeigten Komponenten des Schienenfahr- zeugs 1 werden entsprechend ihren jeweiligen Platz- und Gewichtserfordernissen auf verschiedene Wagen verteilt. Fig. 2 zeigt eine solche beispielhafte Aufteilung der Komponenten des Schienenfahrzeugs 1 auf sechs verschiedene Wagen 28 bis 33, u.zw. einen ersten Wagen 28 mit einer Siloeinheit 34 zur Be- vorratung von neuem Gleisbettmaterial 27; einen Wagen 29 mit der Gleisbett-Rezykliereinrichtung 26; zwei Wagen 30 und 31 mit den Gleisbett-Räum- und -Aufbringeinrichtungen 11, 17, den Un- terbau-Räum- und -Aufbringeinrichtungen 12, 13, 15, 16 und der Unterbau-Rezykliereinrichtung 22; einen Wagen 32 mit einer Si- loeinheit 35 zur Bevorratung von neuem Unterbaumaterial 25; und einen Wagen 33 mit einer Siloeinheit 36 zur Aufnahme des Abraums 13' der unteren Schicht 19. Zwischen und in den Wagen 28 bis 33 verlaufen Förderbänder (in Fig. 2 nicht gezeigt) zur Realisierung der dargestellten Materialflüsse. Bei der in Fig. 2 gezeigten Ausführungsform ist die Gleishebeeinrichtung 9 in eine erste Gleishebeeinheit 9' zum Ausheben des Gleises 4 in einem ersten Abschnitt 10' und eine zweite Gleishebeeinheit 9" zum nochmaligen Anheben des Gleises 4 in einem davon beabstandeten zweiten Abschnitt 10" des Ar- beitsbereichs 10 unterteilt. Dadurch kann sich das Schienen- fahrzeug 1 mit zumindest einem Fahrgestell 37 im Bereich zwischen dem ersten Abschnitt 10' und dem zweiten Abschnitt 10" auf dem vorübergehend auf der unteren Schicht 19 zur Auflagerung kommenden Gleis 4 abstützen. Eine zu diesem Zweck vorteil- hafte Aufteilung der Komponenten auf die Wagen 30 und 31 wird nun anhand der Fig. 3 und 4 näher erläutert, welche den Innenaufbau der Wagen 30 und 31 des Schienenfahrzeugs 1 im Bereich seiner Arbeitsbereichsabschnitte 10' und 10" im Detail zeigen. Gemäß den Fig. 3a und 4a arbeiten die Gleisbett-Räumein- richtung 11 und die erste Räumeinheit 12 im ersten Abschnitt 10' im Wagen 30 und sind jeweils in Form einer Räumkette ausgebildet, welche sowohl in ihrer Räumbreite als auch -tiefe einstellbar ist, wie dem Fachmann bekannt.The rail vehicle 1 usually consists of several cars coupled to a train (although this is not mandatory) and the components of the rail vehicle 1 shown in FIG. 1 are distributed to different cars according to their respective space and weight requirements. Fig. 2 shows such an exemplary division of the components of the rail vehicle 1 on six different cars 28 to 33, u.zw. a first carriage 28 having a silo unit 34 for stocking new track bed material 27; a carriage 29 with the track bed recycler 26; two carriages 30 and 31 with the track bed clearing and application devices 11, 17, the sub-construction clearing and applying devices 12, 13, 15, 16, and the undercarriage recycle device 22; a carriage 32 with a silo unit 35 for storing new substructure material 25; and a carriage 33 with a silo unit 36 for receiving the overburden 13 'of the lower layer 19. Between and in the carriage 28 to 33 run conveyor belts (not shown in Fig. 2) for the realization of the illustrated material flows. In the embodiment shown in Fig. 2, the track lifting device 9 is in a first track lifting unit 9 'for lifting the track 4 in a first portion 10' and a second track lifting unit 9 "for lifting the track 4 again in a spaced second section 10" of Work area 10 divided. As a result, the rail Supporting the vehicle 1 with at least one chassis 37 in the area between the first section 10 'and the second section 10 "on the track 4 temporarily resting on the lower layer 19. A distribution of the components onto the carriages 30 which is advantageous for this purpose and FIG. 31 will now be explained in greater detail with reference to FIGS. 3 and 4, which show in detail the internal structure of the carriages 30 and 31 of the rail vehicle 1 in the region of its working area sections 10 'and 10 ". According to FIGS. 3 a and 4 a, the track bed clearing device 11 and the first clearing unit 12 operate in the first section 10 'in the carriage 30 and are each in the form of a clearing chain, which is adjustable both in its clearing width and in depth, such as known to the skilled person.

Optionally, the sub-base recycle 22 may also include a washing device (not shown) for washing the overburden 12'. The starting material 22 'of the reclaiming device 22 is forwarded via a conveyor belt 45 to the carriage 31 (FIG. 3b).
Die Zerkleinerungs- und Mischeinrichtung 43 kann beispielsweise durch eine Zerkleinerungsschnecke gebildet sein, welcher sowohl der Abraum 12' als auch die Zusatzstoffe 23 auf- gegeben werden. Alternativ kann die Zerkleinerung in einer ge- sonderten Zerkleinerungseinrichtung erfolgen, z.B. in einem Prall- oder Kegelbrecher, und das Einbringen der Zusatzstoffe in einem gesonderten, vor- oder nachgeordneten Mischer.The comminuting and mixing device 43 can be formed, for example, by a comminution screw, which is charged with both the overburden 12 'and the additives 23. Alternatively, the comminution can be carried out in a Separate crushing done, for example, in a baffle or cone crusher, and the introduction of the additives in a separate, upstream or downstream mixer.
Die Zerkleinerungs- und Mischeinrichtung 43 bricht bzw. zerkleinert den Abraum 12' bevorzugt auf eine Körnung von unter 50 mm herab. Die beigegebenen Zuschlagstoffe 23 können, wie dem Fachmann bekannt, sowohl flüssige als auch feste Form haben.The crushing and mixing device 43 breaks or crushes the overburden 12 'preferably down to a grain size of less than 50 mm. The added additives 23 can, as known to those skilled in both liquid and solid form.
Wie in den Fig. 3b und 4b gezeigt, arbeiten die zweite Unterbau-Räumeinheit 13, die erste und die zweite Unterbau-Auf- bringeinheit 15, 16 und die Gleisbett-Aufbringeinrichtung 17 im zweiten Abschnitt 10" im Wagen 31. Auch die zweite Unterbau- Räumeinheit 13 ist als Räumkette ausgebildet (Fig. 4b) und sowohl in ihrer Räumbreite als auch -tiefe einstellbar, wie dem Fachmann bekannt. Der Abraum 13' der zweiten Räumeinheit 13 wird über ein Förderband 46 zum Wagen 36 weitergeleitet und die zweite Unterbau-Aufbringeinheit 16 wird über ein Förderband 47 mit vom Wagen 32 empfangenem neuen PSS-Material 25 versorgt.

Die Erfindung ist nicht auf die dargestellten Ausführungsformen beschränkt, sondern umfaßt alle Varianten und Modifikationen, die in den Rahmen der angeschlossenen Ansprüche fallen. So kann beispielsweise der Unterbau in einer vereinfachten Variante auch nur in einer einzigen Schicht abgeräumt werden, deren Abraum teilweise (ergänzt durch Neumaterial) oder zur Gänze als neue Unterbauschicht rezykliert wird, in welchem Fall sich eine Unterteilung der Unterbau-Räumeinrichtung in mehrere Räumeinheiten und der Unterbau-Aufbringeinrichtung in mehrere Äufbringeinheiten erübrigt. Alternativ kann der Unterbau mit Hilfe von mehr als zwei Räumeinheiten auch in mehr als zwei Schichten abgetragen werden, und der neue Unterbau mit Hilfe von mehr als zwei Aufbringeinheiten auch in mehr als zwei Schichten aufgetragen wer- den, wobei dann die Rezykliereinrichtung den Abraum einer (oder mehrerer) der oberen abgeräumten Schichten zu einer (oder mehreren) der unteren aufgebrachten Schichten rezykliert; gegebenenfalls kann dazu die Rezykliereinrichtung auch in mehrere Re- zykliereinheiten unterteilt sein, welche jeweils eine Schicht rezyklieren. The invention is not limited to the illustrated embodiments, but includes all variants and modifications that fall within the scope of the appended claims. For example, in a simplified variant, the substructure can also be cleared only in a single layer whose overburden is partially recycled (supplemented by virgin material) or entirely as a new subgrade layer, in which case a subdivision of the substructure clearing device into a plurality of clearing units and the Substructure applicator in several Äufbringeinheiten is unnecessary. Alternatively, the substructure can also be removed in more than two layers with the aid of more than two clearing units, and the new substructure can also be applied in more than two layers with the aid of more than two application units, in which case the recycler or more) of the upper cleared layers is recycled to one (or more) of the lower deposited layers; if appropriate, the recycling device can also be subdivided into a plurality of recycling units, which each recycle a layer.
