Abstract

The track has a permanent way with rails (14) laid on sleepers (13), which are supported on a bed (15) of ballast. The bed is supported by a concrete slab (21) which is laid on the ground. The slab has a thickness of at least 0.4 m, and is in the form of a continuous band which is poured in situ. The thickness may also be up to 1.4 m, and pref. may be 0.7 m. The outsides of the slab may have edge covers (22) which project upwards in order to contain the ballast bed. The slab may also have a central cover projecting from its upper surface, and a track may be arranged on each side of it.

Description

Die Erfindung betrifft eine Gleisanlage für schienengebundene Fahrzeuge, insbesondere Eisenbahnen, mit einem Oberbau, der auf Schwellen gelagerte Schienen und ein die Schwellen unterstützendes Schotterbett aufweist, und mit einem den Oberbau tragenden Unterbau, der eine das Schotterbett tragende Tragplatte aus Beton aufweist, die auf einem Erdbauwerk aufgelagert ist.The invention relates to a track system for rail-bound Vehicles, especially railways, with one Superstructure, the rails mounted on sleepers and a die Has gravel bed supporting sleepers, and with a substructure supporting the superstructure, the one the ballast bed bearing load-bearing plate made of concrete, which on is supported by an earth structure.

Bei herkömmlichen Gleisanlagen wird als Oberbau üblicherweise der sogenannte Schotteroberbau verwendet, bei dem die Schwellen auf einem Schotterbett aufliegen. Das Gleis und das Schotterbett sind auf einen Unterbau aufgelagert, über den die vom Eisenbahnfahrzeug ausgeübten Kräfte in den Erdboden abgeleitet werden. Der Schotteroberbau hat sich bisher bewährt, da er eine hohe Flexibilität und Anpassungsfähigkeit besitzt und in relativ einfacher Weise instandzuhalten ist.In conventional track systems is usually used as a superstructure the so-called ballast track used, in which the sleepers rest on a gravel bed. The track and the ballast bed is supported on a substructure, over which the forces exerted by the railway vehicle in be derived from the ground. The ballast track has has proven itself so far because it is highly flexible and Possesses adaptability and is relatively simple Way to maintain.

Es hat sich jedoch gezeigt, daß aufgrund höher werdender Achslasten und Fahrgeschwindigkeiten Schwingungen im Schotterbett auftreten, die zu einem Abbau der Reibung zwischen den Schottersteinen führen, was Schotterumlagerungen zur Folge hat, wodurch das Schotterbett sich in starkem Maße setzt und quer zur Gleisrichtung seitlich ausweicht. Dies bringt eine wesentliche Herabsetzung der Qualität der Gleisanlage mit sich und macht einen hohen Aufwand für die Instandhaltung erforderlich.However, it has been shown that due to increasing Axle loads and driving speeds Vibrations in Ballast bed occur, leading to a reduction in friction lead between the gravel stones, what gravel rearrangements has the consequence of what the ballast bed itself to a large extent and laterally across the track direction evades. This brings a significant reduction in the Quality of the track system with it and makes a high one Maintenance required.

Aus der DE 40 07 710 A1 ist es bei Tunnelbauwerken bekannt, den Schotteroberbau durch eine sogenannte feste Fahrbahn zu ersetzen, bei der das Gleis in oder auf einer festen Betonsohle der Tunnelröhre fest angebracht ist, wodurch eine stabile Positionierung des Gleises relativ zu der Betonsohle gewährleistet ist. Darüber hinaus können bei dieser Ausführung Querkräfte zuverlässig aufgenommen werden, da die Betonsohle seitlich durch die Tunnelwände gestützt ist. Ein Oberbau in Form einer festen Fahrbahn verfügt jedoch nur über eine sehr geringe, im Millimeter-Bereich liegende Korrigierbarkeit des Schienenstranges. Darüber hinaus ist eine sehr hohe Montagegenauigkeit erforderlich und auch an den Unterbau sind wesentlich höhere Anforderungen als bei dem Schotteroberbau zu stellen. Bei festem, im wesentlichen unverformbarem, homogenem Unterbau, wie er in Tunnelabschnitten oder auf längeren Brücken zu finden ist, lassen sich feste Fahrbahnen sinnvoll einsetzen. Wenn jedoch der Unterbau aus einem verformungsfreudigen Erdbauwerk besteht, sind aufwendige Zusatzmaßnahmen notwendig, um die Anforderungen an den Unterbau für eine feste Fahrbahn einhalten zu können. Auf diese Weise sind Gleisanlagen mit einem Oberbau in Form einer festen Fahrbahn häufig sehr teuer in der Herstellung.From DE 40 07 710 A1 it is known for tunnel structures the ballast track by a so-called fixed To replace a track where the track is in or on a solid concrete base of the tunnel tube is firmly attached, which ensures a stable positioning of the track relative to the concrete base is guaranteed. Furthermore can shear forces reliably with this version can be included, because the concrete base through the side Tunnel walls is supported. A superstructure in the form of a however, the solid carriageway has only a very small, correctability of the Rail track. It is also very high Assembly accuracy required and also on the substructure are much higher requirements than with ballast track to deliver. In the case of a solid, essentially non-deformable, homogeneous substructure, such as in tunnel sections or can be found on longer bridges use solid lanes wisely. However, if the Substructure consists of a deformation-friendly earthwork, costly additional measures are necessary in order to Requirements for the substructure for a solid carriageway to be able to comply. This is how track systems are often with a superstructure in the form of a solid carriageway very expensive to manufacture.

Aus der DE 41 00 881 A1 ist es bekannt, trogförmige Betonfertigteile zur Bildung einer Tragrinne aneinanderzureihen und in der Tragrinne ein Schotterbett anzuordnen, das die Gleise in bekannter Weise trägt und durch die Seitenteile der Tragrinne seitlich abgestützt ist. Die Betonfertigteile sind auf einem Erdbauwerk, d.h. dem bearbeiteten Erdboden aufgelegt, wobei unterhalb der Betonplatte eine Planumsschutzschicht und eine Frostschutzschicht ausgebildet sind.From DE 41 00 881 A1 it is known to be trough-shaped Precast concrete parts to form a support channel and arrange a ballast bed in the trough, that carries the tracks in a known manner and through the side parts of the support channel are supported laterally. The precast concrete elements are on an earth structure, i.e. the processed soil, being below the Concrete slab with a formation protection layer and a frost protection layer are trained.

Erdbauwerke können im Laufe der Zeit relativ großen Verformungen unterliegen, was zu örtlichen Setzungen einzelner Betonfertigteile bzw. der Tragrinne führen kann. Um diesen Wirkungen vorzubeugen, ist eine sehr aufwendige und präzise Bearbeitung des Erdbodens notwendig, was jedoch sehr teuer ist. Darüber hinaus können insbesondere bei hohen Fahrgeschwindigkeiten der Züge Schwingungen und Erschütterungen auftreten. Die dynamischen Lasteinwirkungen des Eisenbahnbetriebes verursachen an dem tragenden Gleisrost und dem Schotterbett oder sonstigen Tragelementen Schwingungen, die über den Untergrund bzw. Unterbau weitergegeben werden und bereichsweise auf das angrenzende Umfeld wirken können. Bei naheliegender baulicher Nutzung und insbesondere bei ungünstigen Bodenverhältnissen lassen sich die zulässigen Werte für die Erschütterungen bei einer konventionellen Streckenausbildung mit einem Schotteroberbau oder einer sogenannten festen Fahrbahn häufig nicht einhalten. Dies kann insbesondere bei schwingungsempfindlichen Gebäuden zu Beeinträchtigungen oder Schäden führen. Gegebenenfalls ist sogar eine Aufgabe des Bauvorhabens oder eine Umlegung der Trasse erforderlich.Earthworks can be relatively large over time Deformations are subject to local subsidence of individual precast concrete parts or the support channel can. To prevent these effects is a very important one complex and precise cultivation of the soil necessary, however, which is very expensive. In addition, you can especially at high train speeds Vibrations and shocks occur. The dynamic Cause loads from railway operations on the load-bearing track grate and the ballast bed or other supporting elements vibrations that go over the surface or substructure are passed on and in some areas can affect the surrounding environment. With obvious structural use and especially in the case of unfavorable ones Soil conditions allow the permissible values for the vibrations in a conventional route training with a ballast track or a so-called often do not keep on a solid road. This can especially in buildings sensitive to vibrations Impairment or damage. Possibly is even a task of the building project or a reallocation the route required.

Der Erfindung liegt die Aufgabe zugrunde, eine Gleisanlage der genannten Art zu schaffen, die eine formstabile Halterung der Gleise sicherstellt, eine wesentlich verbesserte Korrigierbarkeit der Gleise nach Verformungen des Untergrundes oder Unterbaus bietet und eine Anpassung der Schwingungs- bzw. Erschütterungseigenschaften an die bauliche Gegebenheiten ermöglicht. The invention has for its object a track system of the type mentioned to create a dimensionally stable Securing the rails ensures a much improved Correctability of the tracks after deformation of the subsurface or substructure and an adjustment the vibration or vibration properties to the structural conditions.

Diese Aufgabe wird bei einer Gleisanlage der genannten Art erfindungsgemäß dadurch gelöst, daß die Tragplatte als kontinuierliches, in Ortbeton hergestelltes Band ausgebildet ist und eine Stärke von mindestens 0,40 m aufweist.This task is performed on a track system Art solved according to the invention in that the support plate as a continuous belt made of in-situ concrete is trained and a thickness of at least 0.40 m having.

Die Schwingungs- und Erschütterungsprobleme lassen sich mit der erfindungsgemäßen massiven Tragplatte, die einen einheitlich, monolithisch wirkenden Körper großer Masse, einen sogenannten Massekörper, darstellt, nach dem Prinzip eines Masse-Feder-Systems lösen. Die Stärke der Tragplatte wird dabei entsprechend den baulichen Gegebenheiten so gewählt, daß ein wirksamer Schutz gegen Erschütterungen erreicht wird. Vorzugsweise werden die bei bekannten Gleisanlagen ebenfalls vorhandenen Planumsschutzschicht und Frostschutzschicht sowie gegebenenfalls Anteile des Schotterbettes durch ein geeignetes, dauerhaftes Bindemittel, insbesondere Zement, Kleber etc., zu dem Massekörper verbunden. Die von den fahrenden Zügen verursachten dynamischen Lasten, werden gewichts- und geschwindigkeitsabhängig über das als Feder wirkende Schotterbett als rasche Impulse in typischen Frequenzen an den Unterbau weitergeleitet. Die von dem Schotterbett übertragenen Impulse erregen den Massenkörper, der je nach Bemessung der Masse eine Schwingungs- und Frequenzänderung bewirkt. Auf diese Weise läßt sich ein auf die Eigenfrequenz der zu schützenden, angrenzenden Bebauung abgestimmtes Schwingungssystem schaffen, dessen Eigenfrequenz unter der Eigenfrequenz der schwingenden Teile der zu schützenden Bauwerke liegt. Somit können übermäßige Erschütterungen sowie unzulässiger Körperschall durch Anpassung an die örtlichen baulichen Gegebenheiten vermieden werden. The vibration and vibration problems can be solved with the massive support plate according to the invention, the one uniform, monolithic body of large mass, a so-called mass body, according to the principle of a mass-spring system. The strength of the Carrier plate is made according to the structural conditions chosen so that effective protection against shocks is achieved. Preferably, the at known track systems also existing formation protection layer and frost protection layer as well as if necessary Parts of the ballast bed by a suitable, permanent Binders, especially cement, glue, etc., too connected to the mass body. The one from the moving trains caused dynamic loads, are weight and depending on the speed via that acting as a spring Ballast bed as rapid impulses in typical frequencies forwarded to the substructure. The one from the ballast bed transmitted impulses excite the mass body that ever after dimensioning the mass a change in vibration and frequency causes. In this way, one can Natural frequency of the neighboring buildings to be protected create a coordinated vibration system, its natural frequency below the natural frequency of the vibrating parts of the structures to be protected. Thus, excessive Shocks and impermissible structure-borne noise Adaptation to the local structural conditions avoided will.

Der Massekörper sollte unterhalb des Schotteroberbaus als monolithisch wirkende, verbundene Masse hergestellt werden, wobei er vorzugsweise die Planumsschutzschicht und Frostschutzschicht ersetzt. Es ist jedoch auch möglich, die massive Tragplatte direkt auf die Planumsschutzschicht aufzulegen. Gegebenenfalls wird die Masse des Massekörpers durch anteiliges Verkleben des Schotters und klebende Verbindung dieses Schotterkörpers mit dem eigentlichen Massekörper vergrößert. Die im Masse-Federsystem vorhandene Federwirkung ergibt sich in diesem Fall aus den Federanteilen der Schienenzwischenlagen und des verbleibenden unverklebten Schotters. Vorzugsweise wird lediglich der Schotterrandbereich in den Böschungselementen, der sogenannte Vorkopfschotter, verklebt und eine geringe Oberflächenverklebung durchgeführt, um Schotterflug zu vermeiden. Falls eine weitere Vergrößerung der Masse über die Maximalstärke des aus Planumsschutzschicht und Frostschutzschicht bestehenden Schichtenpakets notwendig sein sollte, kann auch eine weitere Vergrößerung der Stärke des Massenkörpers durch Tieferlegung des Erdplanums erreicht werden.The mass body should be below the ballast superstructure monolithically acting, connected mass are produced, preferably the formation protection layer and Frost protection layer replaced. However, it is also possible the massive base plate directly onto the formation protection layer to hang up. If necessary, the mass of the Mass body through partial bonding of the ballast and adhesive connection of this ballast body with the actual mass body enlarged. The mass-spring system existing spring action results in this case from the spring components of the rail liners and the remaining unglued ballast. Preferably only the gravel edge area in the slope elements, the so-called head ballast, glued and one little surface bonding done to gravel flight to avoid. If a further enlargement of the Mass over the maximum thickness of the formation protection layer and anti-freeze layer existing layer package necessary should also be a further enlargement the strength of the mass body by lowering the Earth planum can be reached.

Es ist jedoch auch möglich, die konventionelle Funktion des Schotteroberbaus vollständig zu erhalten und diesen vom Massekörper zu trennen, was beispielsweise unterstützend auch durch Einlegen einer Unterschottermatte als Dämmung erreicht werden kann. Alternativ oder zusätzlich dazu kann auch der Massekörper mit entsprechenden Dämmatten umhüllt werden.However, it is also possible to use the conventional function of the ballast superstructure to be completely preserved and this to separate from the mass body, which is, for example, supportive also by inserting a sub-ballast mat as Insulation can be achieved. Alternatively or additionally the mass body can also be used with appropriate insulation mats be enveloped.

Die Korrigierbarkeit der Gleisanlage bei eventuellen Verformungen des Unterbaus oder Untergrundes wird mittels konventioneller Bearbeitungsmaßnahmen des Schotterbetts in hohem Maße erreicht. The correctability of the track system in the event of any Deformation of the substructure or subsurface is determined by means of conventional processing measures for the ballast bed achieved to a great extent.

Als Grundmaterialien für den Massekörper eignen sich in kostengünstiger Weise beispielsweise die entsprechenden Tragschichten (Planumsschutzschicht, Frostschutzschicht), günstige rollige oder gebrochene Materialien, Recyclingmaterial ggf. mit Schwergewichtszugabe sowie in bestimmten Fällen auch eingekapselte kontaminierte Materialien. Die genannten Materialien werden mit einem Bindemittel, vorzugsweise Zement oder Bitumen, zu der monolithisch wirkenden Masse verbunden. Der Massekörper ist vorzugsweise unbewehrt, besitzt jedoch eine Dauerfestigkeit, die etwa im Bereich der Betonklassen B15 bis B25 liegt. Bereichsweise kann sowohl die Stärke durch Schwergewichtszusätze oder besondere Dämmaßnahmen reduziert und die Festigkeit beispielsweise durch Einlage von Bewehrung variiert bzw. erhöht werden.Suitable base materials for the mass body are in for example, the corresponding ones in a cost-effective manner Base layers (formation protection layer, frost protection layer), cheap rolled or broken materials, recycling material if necessary with the addition of heavy weights and in certain Cases also encapsulated contaminated materials. The materials mentioned are mixed with a binder, preferably cement or bitumen, to the monolithic acting mass connected. The mass body is preferred unreinforced, but has a fatigue strength that is in the range of concrete classes B15 to B25. In some areas, the strength can be increased by adding heavy weights or special insulation measures reduced and the strength, for example, by inserting reinforcement be varied or increased.

Der Unterbau bzw. Untergrund hat im wesentlichen nur noch eine Tragfunktion für die massive Tragplatte zu übernehmen, ohne daß die Gefahr von Wasserdurchtritten besteht oder ein komplizierter Schichtenaufbau notwendig ist. Auf aufwendige Entwässerungsmaßnahmen kann dabei verzichtet werden. Durch die hohe Masse des Systems werden nach dem Prinzip eines Masse-Feder-Systems auch die dynamischen Belastungen und erzeugten Schwingungen in Frequenz und Intensität verändert und gedämpft, so daß hierauf gerichtete zusätzliche Maßnahmen weitgehend entfallen können. Die relativ große Stärke der Tragplatte, die größer als 0,4 m ist und etwa in einem Bereich von 0,4 m bis 1,4 m, und vorzugsweise bei etwa 0,7 m liegt, erfordert keine weiteren Frostschutzmaßnahmen und macht die bei anderen Systemen notwendige Planumsschutzschicht und/oder Frostschutzschicht überflüssig.The substructure or subsoil essentially only has to take over a supporting function for the massive supporting plate, without the risk of water penetration or a complicated layer structure is necessary. On elaborate drainage measures can be dispensed with will. Due to the high mass of the system Principle of a mass-spring system including dynamic ones Loads and vibrations generated in frequency and Intensity changed and subdued, so that directed towards it additional measures can largely be omitted. The relatively large strength of the support plate, the greater than Is 0.4 m and approximately in a range from 0.4 m to 1.4 m, and preferably about 0.7 m does not require any other frost protection measures and does that for others Systems necessary formation protection layer and / or frost protection layer superfluous.

Die mit der erfindungsgemäßen Gleisanlage zu erzielenden Systemsteifigkeiten können variiert und an die Elastizitätswerte anderer Gleisanlagenarten angeglichen werden, so daß Systemübergänge auf andere Gleisanlagen speziell bei Brücken oder Tunneln keine Probleme aufwerfen und keine speziellen Konstruktionen erfordern.Those to be achieved with the track system according to the invention System stiffness can vary and adhere to the elasticity values other types of track systems are adjusted, so that system transitions to other track systems specifically pose no problems with bridges or tunnels and do not require special constructions.

In bevorzugter Ausgestaltung ist erfindungsgemäß vorgesehen, daß auf der Tragplatte außenseitige, nach oben vorstehende Randkappen angeordnet sind, die mit der Tragplatte einen das Schotterbett aufnehmenden rinnenförmigen Tragkörper bilden. Bei zweigleisigen Anlagen kann auf der Oberseite der Tragplatte zwischen den Gleisen auch eine nach oben vorstehende Mittelkappe ausgebildet sein, so daß jedem Gleis ein eigener rinnenförmiger Tragkörper zugeordnet ist. Auch bei der erfindungsgemäßen Gleisanlage sind die Schwellen in bzw. auf einem Schotterbett gelagert. Die Formbeständigkeit des Schotterbettes wird durch den oder die formhaltenden, rinnenförmigen Tragkörper gestützt, so daß übermäßige Setzungen des Schotterbettes oder dessen Ausweichen in Querrichtung vermieden werden können. Insbesondere können die aus dem Schienenbetrieb speziell bei hohen Geschwindigkeiten resultierenden Quer- bzw. Seitenkräfte durch die Randkappen und/oder die Mittelkappe aufgenommen werden. Der massive rinnenförmige Tragkörper ist sehr störungsunanfällig und bringt somit nur geringe Unterhaltskosten mit sich. Er wirkt über den gesamten Querschnitt der Gleisanlage und ermöglicht somit eine einfache Entwässerung. Es hat sich gezeigt, daß spezielle Anforderungen an den Unterbau oder hinsichtlich Schwingungsbelastungen bei der erfindungsgemäßen Gleisanlage nicht zu stellen sind. Die Randkappen und/oder die Mittelkappe können in ihrer Höhe variieren und bei Bedarf auf die maximale Querneigung der Gleise bzw. die auftretenden Seitenkräfte aufgerichtet sein.In a preferred embodiment, the invention provides that on the outside of the support plate, upwards protruding edge caps are arranged with the Support plate a gutter-shaped receiving the ballast bed Form support body. In the case of double-track systems, on the top of the support plate between the tracks also formed an upstanding central cap be so that each track has its own gutter-shaped Support body is assigned. Even with the invention Track systems are the sleepers in or on a ballast bed stored. The dimensional stability of the ballast bed is by the shape-keeping, gutter-shaped Supported body so that excessive settlement of the Ballast bed or its evasion in the transverse direction can be avoided. In particular, from the Rail operation especially at high speeds resulting transverse or lateral forces through the edge caps and / or the middle cap can be included. Of the massive trough-shaped support body is very insensitive to faults and therefore brings only low maintenance costs yourself. It affects the entire cross-section of the track system and thus enables easy drainage. It has been shown that special requirements for the Substructure or with regard to vibration loads at the Track system according to the invention are not to be provided. The Edge caps and / or the middle cap can be in height vary and if necessary to the maximum bank of the Tracks or the lateral forces that occur are erected be.

Da die Schwellen weiterhin in einem Schotterbett gelagert sind, kann die Schienenlage bei Bedarf in einfacher Weise korrigiert werden, wie es auch bei dem bekannten Schotteroberbau der Fall ist. Die massive Tragplatte wird unterhalb des Schotterbettes bestehender bzw. neu zu bauender Strecken auf Erdbauabschnitten, also unterhalb des Planums im Regelquerschnitt von Eisenbahnstrecken eingebaut und ersetzt dort vorzugsweise die Planumsschutzschicht und die Frostschutzschicht.Because the sleepers are still stored in a ballast bed are, the rail position can easily if necessary be corrected, as is also the case with the known ballast track the case is. The massive support plate is existing or new below the ballast bed building routes on earthwork sections, i.e. below of the formation in the regular cross section of railway lines installed and preferably replaces the formation protection layer there and the frost protection layer.

Die Randkappen und/oder die Mittelkappe können entweder an die Tragplatte einstückig angeformt oder auch als separate vorgefertigte Bauteile ausgebildet sein, die dann an der Tragplatte befestigt werden. Vorzugsweise wird zuerst die massive Tragplatte in Ortbeton als im wesentlichen kontinuierliches Band ausgebildet, woraufhin die Randkappen und/oder die Mittelkappe in Ortbetonausführung über eine formschlüssige Verbindung mit der Tragplatte verbunden werden. Es ist jedoch auch möglich, die als Fertigteil hergestellten Randkappen und/oder die Mittelkappe mit der Tragplatte zu verdübeln.The edge caps and / or the middle cap can either integrally formed on the support plate or as separate prefabricated components can be formed, the then be attached to the support plate. Preferably the solid support plate is first cast in situ as in essentially continuous band, whereupon the edge caps and / or the center cap in in-situ concrete design via a positive connection with the Support plate are connected. However, it is also possible the edge caps produced as a finished part and / or the Dowel the center cap with the support plate.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, daß die innere Wandung der Randkappen und/oder der Mittelkappe derart geneigt ist, daß sie einen sich zum freien Ende hin verjüngenden Querschnitt besitzen. Die dem Gleis zugewandte Seite der Randkappen und/oder der Mittelkappe ist auf diese Weise in der Neigung so gestaltet, daß sie der Richtung der in dem Schotter entstehenden Kräfte möglichst flächig senkrecht entgegen wirken kann.In a preferred embodiment of the invention, that the inner wall of the edge caps and / or the Center cap is inclined so that it is one for have a free end tapering cross-section. The side of the edge caps facing the track and / or the In this way, the center cap is designed so that the inclination that they correspond to the direction of those emerging in the gravel Counteract forces vertically as far as possible can.

Die Höhe der Randkappen und/oder der Mittelkappe bemißt sich nach der einzurichtenden Schotterbettstärke und dabei in der Geometrie des Gesamtquerschnitts derart, daß die Stützfunktion des Schotterbettes und die Querkraftaufnahme auch bei maximaler Überhöhung des Schienenstranges gewährleistet ist. The height of the edge caps and / or the middle cap is measured depending on the ballast bed thickness to be set up and in the geometry of the overall cross section such that the support function of the ballast bed and the shear force absorption even when the track is raised to the maximum is guaranteed.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, daß das Schotterbett zur Erhöhung der Seitenstabilität des Schotters und für den Erschütterungsschutz in sich zumindest teilweise verklebt ist. Der verklebte Schotterkörper stellt in Verbindung mit der massiven Tragplatte und den seitlich stützenden Randkappen und/ oder der Mittelkappe ein stabiles kräfte- und formbeständiges Gesamtsystem dar. Der verfestigte und querkraftbeständige verklebte Schotterkörper kann bei Setzungen des Untergrundes oder Unterbaus jederzeit nach mechanischem Aufbrechen neu geformt werden, so daß die Schienen in ihrer Lage und Ausrichtung nachjustiert werden können.In a preferred embodiment of the invention, that the ballast bed to increase the lateral stability of the ballast and for vibration protection in is at least partially glued. The glued Ballast body connects to the massive Support plate and the side supporting edge caps and / or the center cap is a stable, stable shape Entire system. The solidified and shear resistant glued ballast can settle when the Substructure or substructure at any time according to mechanical Breaking open to be reshaped so that the rails in their position and orientation can be readjusted.

Die Tragplatte und die Randkappen und/oder die Mittelkappe bestehen üblicherweise aus Beton, insbesondere B15 oder B25, wobei gegebenenfalls auch aufbereitete Zuschlagstoffe, Recyclingmaterial oder gegebenenfalls aufbereitete, eingekapselte und geeignete kontaminierte Materialien sowie andere Bindemittel als Zement, beispielsweise Bitumen, zur Herstellung der Tragplatte Verwendung finden können. Die Oberfläche der Tragplatte ist weitestgehend geschlossen und wasserableitend. Bei Bedarf kann zwischen dem Schotterbett und dem Tragkörper, d.h. der Tragplattenoberfläche und den inneren Wandungen der Randkappen und/oder der Mittelkappe eine Unterschottermatte eingelegt werden. Die Möglichkeit, nur Teilverklebungen des Schotterbettes vorzunehmen und Unterschottermatten unter und seitlich des Schotters einzulegen, eröffnet den Weg zu einem weichen, federnden Gesamtsystem mit variierbarer Federwirkung.The support plate and the edge caps and / or the center cap usually consist of concrete, especially B15 or B25, where appropriate also processed aggregates, Recycled material or where appropriate prepared, encapsulated and suitable contaminated Materials and binders other than cement, for example Bitumen, for the production of the base plate Can find use. The surface of the support plate is largely closed and water-draining. At Needs can be between the ballast bed and the supporting body, i.e. the support plate surface and the inner walls the edge caps and / or the middle cap a sub-ballast mat be inserted. The possibility of only partial gluing of the ballast bed and sub-ballast mats under and to the side of the ballast, opens the way to a soft, springy overall system with variable spring action.

In Weichenbereichen werden lediglich die Randkappen und/oder die Mittelkappe im Bereich der durchlaufenden Schwellensätzen unterbrochen. Auf diese Weise ist ein unkompliziertes weichengeeignetes Gleisanlagensystem geschaffen.Only the edge caps are used in the switch areas and / or the center cap in the area of the continuous Threshold sets interrupted. That way is a uncomplicated soft track system created.

Die massive, vorzugsweise einstückige Ausgestaltung der Tragplatte mit den seitlichen Randkappen und/oder der Mittelkappe und die damit erzielte Verbundwirkung kommt über den Querschnitt einer eingleisigen oder zweigleisigen Strecke einem entsprechenden Trog oder Kanal gleich, in dem das Schotterbett, das gegebenenfalls zu einem stabilen Schotterkörper verklebt ist, paßgenau und in formstabiler Weise aufgenommen ist. Bei einer zweigleisigen Strecke kann durch die Randkappen in Zusammenwirken mit der Mittelkappe eine entsprechende Trog- oder Kanalwirkung für jedes Gleis vorgesehen sein. In Weiterbildung der Erfindung ist vorgesehen, daß zumindest die Oberseite der Tragplatte eine Querneigung besitzt, die etwa 1:20 betragen sollte. Bei eingleisigen Strecken kann eine einseitige Neigung vorgesehen sein. Bei zweigleisigen Strecken sollte vorgesehen sein, daß die Oberseite der Tragplatte ausgehend von deren Längsmittelebene zu beiden Seiten eine abfallende Querneigung besitzt, so daß eine sogenannte Dachneigung verwirklicht ist. Die Querneigung der Oberseite der Tragplatte stellt eine Wasserableitung an der Tragplatte zu den Seiten der Gleisanlage sicher. Die lückenlose Überdeckung des Unterbaus durch die Tragplatte bietet für diesen einen sicheren Schutz vor eindringendem Wasser.The massive, preferably one-piece design of the Support plate with the side edge caps and / or the Middle cap and the resulting composite effect comes across the cross section of a single track or double track Same route as a corresponding trough or channel, in which the ballast bed, which may become a stable ballast body is glued, fits snugly and in dimensionally stable is included. With a double track Stretch can interact through the edge caps a corresponding trough or channel effect with the middle cap be provided for each track. In further training the invention provides that at least the top the support plate has a cross slope that is about 1:20 should be. In the case of single-track routes, one one-sided inclination may be provided. With double-track It should be provided that the top of the stretch Support plate starting from their longitudinal median plane to both Sides has a sloping bank, so that a so-called roof pitch is realized. The bank the top of the support plate provides a water drain secure on the support plate to the sides of the track system. The complete covering of the substructure by the support plate offers secure protection against intrusion Water.

Die massive Ausgestaltung der Tragplatte sowie der Randkappen bietet die Möglichkeit, auch andere streckenbegleitende Ausrüstungen wie beispielsweise Schallschutzwände, Kabelkanäle etc. an dem Tragkörper zu montieren. Insbesondere ist vorgesehen, daß auf der im wesentlichen ebenen Oberseite der Randkappen und/oder der Mittelkappe eine Schallschutzwand angeordnet ist. Die Randkappen und/oder die Mittelkappe können somit als Auflager für die Schallschutzwand dienen, wobei sie vorzugsweise mit Köchern für die Aufnahme der Halterungen der Schallschutzelemente ausgerüstet werden. Alternativ wird die Ausbildung der Köcher so vorgenommen, daß sie in die Tragplatte hinein oder bei Bedarf für eine Tiefgründung durch die Tragplatte hindurch reichen können. Um die Schallschutzwand in optimaler Entfernung von der Schiene bzw. der Schallquelle anordnen zu können, kann vorgesehen sein, die Randkappen und/oder die Mittelkappe gegebenenfalls zu verbreitern.The massive design of the support plate and the edge caps offers the possibility of other route accompanying Equipment such as soundproof walls, To install cable ducts etc. on the supporting body. In particular, it is provided that in essence flat top of the edge caps and / or the center cap a soundproof wall is arranged. The edge caps and / or the center cap can thus be used as a support for serve the soundproofing wall, preferably with Quivers for the mounting of the holders of the soundproofing elements be equipped. Alternatively, the Training the quiver made so that they in the Support plate into it or if necessary for a deep foundation can reach through the support plate. To the Soundproof wall at an optimal distance from the rail or to be able to arrange the sound source can be provided be the edge caps and / or the center cap if necessary to broaden.

Dabei können die Randkappen und/oder die Mittelkappe als Gründungsbalken für die Schallschutzwände ausgebildet sein, was den Vorteil mit sich bringt, daß die Randkappen und/oder die Mittelkappe mit relativ geringer Breite als kontinuierliches Bauteil über die gesamte Länge der Gleisanlage ausgebildet sein können, während sie in den Abschnitten, in denen die Anordnung einer Schallschutzwand notwendig ist, als Gründungsbalken die optimale Entfernung der Schallschutzwand von der Schiene sicherstellt. Auf diese Weise kann auch die Höhe der Schallschutzwand gering gehalten bzw. optimiert werden, was kostenmäßig vorteilhaft ist. Darüber hinaus kann die Schallschutzwand somit außerhalb des für die Züge freizuhaltenden Lichtraumprofils gehalten werden.The edge caps and / or the center cap can be used as Foundation beams designed for soundproof walls be, which has the advantage that the edge caps and / or the middle cap with a relatively small width than continuous component over the entire length of the Track system can be trained while in the Sections in which the arrangement of a soundproof wall is necessary as the foundation beam the optimal Ensures removal of the soundproof wall from the rail. In this way, the height of the soundproof wall be kept low or optimized what is economically advantageous. In addition, the Soundproof wall outside of that to be kept free for the trains Clearance profile can be kept.

Die Schallschutzwand kann in bekannter Weise in Stahloder Betonausführung erstellt werden und besitzt vorzugsweise in bestimmten Abständen angeordnete Durchgangsmöglichkeiten.The soundproof wall can be made in steel or in a known manner Concrete finish can be created and preferably owns Passages arranged at certain intervals.

Es ist bekannt, daß bei schienengebundenen Fahrzeugen die hauptsächliche Schallquelle im Rad-Schienen-Bereich liegt. Um eine gute Schallabsorption zu erreichen, ist in Weiterbildung der Erfindung vorgesehen, daß die Schallschutzwand auf der dem Gleis zugewandten Seite geneigte, die Schallwellen auf das Schotterbett richtende Reflexionsflächen besitzt. Die auf das Schotterbett gerichteten Schallwellen werden aufgrund der dortigen ungleichmäßig strukturierten Oberfläche ungerichtet bzw. in viele verschiedene Richtung reflektiert und auf diese Weise absorbiert. Vorzugsweise werden die Reflexionsflächen von einer Vielzahl geneigter Teilflächen gebildet, wobei diese unterschiedliche Neigungen besitzen können, um die von der Schallquelle Rad-Schiene ausgehenden Schallwellen wirkungsvoll auf das absorbierende Schotterbett richten zu können.It is known that in rail vehicles main sound source in the wheel-rail area lies. To achieve good sound absorption, in Development of the invention provided that the soundproof wall inclined on the side facing the track, the sound waves reflecting on the ballast bed reflecting surfaces owns. The ones aimed at the ballast bed Sound waves become uneven due to the there structured surface undirected or in many reflecting different direction and that way absorbed. Preferably, the reflective surfaces of formed a plurality of inclined partial surfaces, wherein these can have different inclinations to the sound waves emanating from the sound source wheel-rail aim effectively at the absorbent ballast bed to be able to.

Um das sich aufgrund der Querneigung der Oberseite der Tragplatte an einer oder an beiden Seiten des rinnenförmigen Tragkörpers ansammelnde Wasser abführen zu können, ist vorzugsweise vorgesehen, daß in den Randkappen und/ oder der Mittelkappe querverlaufende Abflußkanäle ausgebildet sind, die über die Gleislänge in beliebigen Abständen angeordnet sind. Vorzugsweise sollten in der Tragplatte oder den Randkappen und/oder der Mittelkappe querverlaufende Kabelkanäle ausgebildet sein.This is due to the bank of the top of the Support plate on one or both sides of the trough-shaped To be able to drain the water from the supporting body, it is preferably provided that in the edge caps and / or the central cap formed transverse drainage channels are over the track length at any intervals are arranged. Preferably in the Support plate or the edge caps and / or the center cap transverse cable ducts should be formed.

Die erfindungsgemäße Gleisanlage kann entweder mit einem bekannten, längs der Gleisanlage verlaufenden, erdverlegten Kabelkanal versehen sein, es ist jedoch auch möglich, die in Längsrichtung verlaufenden Kabelkanäle in den Tragkörper zu integrieren oder an diesem anzubringen. Die Kabelkanäle sind in bekannter Weise mittels einer Abdeckung verschlossen.The track system according to the invention can either with a well-known, buried along the track system Cable duct, but it is also possible the longitudinal cable ducts in the Integrate support body or attach to it. The cable channels are in a known manner by means of a Cover closed.

Vorzugsweise lagern die Randkappen auf der gleisabgewandten Seite den längsverlaufenden Kabelkanal bekannter Form, der entweder einstückig mit den Randkappen ausgebildet sein kann oder an diesen befestigt ist. Letzteres kann beispielsweise durch einen an der Randkappe ausgebildeten seitlich vorstehenden Kragarm erreicht werden, auf den der Kabelkanal aufgesetzt ist. Die Oberseiten der Randkappe und des zugeordneten Kabelkanals sollten zusammen eine durchgehende begehbare Fläche neben dem Gleiskörper bilden. Alternativ oder zusätzlich können die Kabelkanäle auch in die Mittelkappe integriert sein.The edge caps preferably rest on the side facing away from the track Side of the longitudinal cable duct known Form that is either integrally formed with the edge caps can be or is attached to this. The latter can, for example, by a trained on the edge cap cantilever projecting from the side can be reached, on which the cable duct is placed. The tops of the Edge cap and the assigned cable duct should be together a continuous accessible area next to the track body form. Alternatively or additionally, the Cable ducts can also be integrated in the center cap.

Der Massekörper besitzt zumindest auf seiner Oberseite eine Neigung von vorzugsweise 1:20, was beispielsweise durch Ausgestaltung des Massekörpers mit einem parallelogramm-artigen Querschnitt erreicht werden kann. Bei eingleisigen Strecken ist eine einseitige Neigung ausreichend, während zur Erzielung einer ausreichenden Wasserableitung bei zweigleisigen Strecken eine Dachneigung vorgesehen sein sollte.The mass body has at least on its top an inclination of preferably 1:20, for example by designing the mass body with a parallelogram-like Cross section can be achieved. At single-track routes, a one-sided incline is sufficient, while achieving sufficient Water drainage on two-track lines a roof pitch should be provided.
