Abstract

The invention relates to a track arrangement for rail mounted vehicles, especially railways, comprising a superstructure with rails arranged on railway sleepers and a ballast bed (24) for supporting said railway sleepers. The superstructure of at least one track is housed in a U-shaped concrete trough extending along the length of the railway and having a base plate as well as, on opposite faces, marginal caps extending upwards and laterally supporting the ballast bed. At least one drain (17) is provided in the trough for draining its inner space. In order to keep subterranean waters from entering the trough simply and reliably, a closing device associated with the drain is provided to at least prevent the water from entering the trough inner space through the drain. The closing device can be a check valve or a shutter mounted in such a way that it is adjustable.

Description

Gleisanlage für schienengebundene Fahrzeuge Track system for rail vehicles
Die Erfindung betrift eine Gleisanlage für schienengebundene Fahrzeuge, insbesondere Eisenbahnen, mit einem Oberbau, der auf Schwellen gelagerte Schienen und ein die Schwellen unterstützendes Schotterbett aufweist, wobei der Oberbau zumindest eines Gleises in einem in Längsrichtung der Gleisanlage verlaufenden, U-förmigen Trog aus Beton aufgenommen ist, der eine Bodenplatte und an entgegengesetzten Seiten nach oben vorstehende, das Schotterbett seitlich abstützende Randkappen aufweist, wobei im Trog zumindest eine Abflußleitung zur Entwässerung des Troginnenraums vorgesehen ist .The invention relates to a track system for rail-bound vehicles, in particular railways, with a superstructure which has rails mounted on sleepers and a ballast bed supporting the sleepers, the superstructure receiving at least one track in a U-shaped trough made of concrete running in the longitudinal direction of the track system is which has a base plate and on opposite sides upwardly projecting edge caps which laterally support the ballast bed, at least one drain line being provided in the trough for draining the interior of the trough.
Seit langer Zeit wird bei Eisenbahn-Gleisanlagen als Oberbau der sogenannte Schotteroberbau verwendet, bei dem die Schwellen auf einem Schotterbett aufliegen, das seinerseits auf einem Unterbau aufgelagert ist, über den die vom Eisenbahnfahrzeug ausgeübten Kräfte in den Erdboden abgeleitet werden. Der Schotteroberbau hat sich bisher bewährt, da er eine hohe Flexibilität und Anpas- sungsfähigkeit besitzt und in relativ einfacher Weise instandzuhalten ist. Für eine ordnungsgemäße Funktionsfähigkeit des Schotteroberbaus ist es notwendig, zuverlässig zu verhindern, daß dieser durch eventuell aufsteigen- des Grundwasser überschwemmt oder unterspült wird. Wenn Gleisanlagen in Geländeabschnitten mit hohem Grundwasserstand errichtet werden sollen, ist es daher notwendig und üblich, den gesamten Verkehrsraum, d.h. die Gleisanlage mit allen Nebenbauwerken wie seitlichen Masten, Schall- schutzwänden etc. mit einer wasserdichten Betonwanne unterseitig zu umgeben. Da eine derartige Betonwanne bautechnisch aufwendig ist und relativ große Abmessungen aufweist, sind mit dieser Vorgehensweise sehr hohe Kosten verbunden. Darüber hinaus treten bei derartigen Betonwan- nen bei steigendem Grundwasser häufig Auftriebsprobleme auf, die zusätzliche Verankerungen notwendig machen.For a long time the so-called gravel superstructure has been used as the superstructure in railway track systems, in which the sleepers rest on a ballast bed, which in turn is supported on a substructure, via which the forces exerted by the railway vehicle are dissipated into the ground. So far, the ballast track has proven itself because it is highly flexible and adaptable ability and is relatively easy to maintain. For the gravel superstructure to function properly, it is necessary to reliably prevent it from being flooded or submerged by any rising groundwater. If track systems are to be erected in sections of the ground with a high groundwater level, it is therefore necessary and customary to surround the entire traffic area, ie the track system with all auxiliary structures such as side masts, soundproof walls, etc., on the underside with a waterproof concrete tank. Since such a concrete trough is structurally complex and has relatively large dimensions, this procedure involves very high costs. In addition, buoyancy problems often arise with such concrete troughs with increasing groundwater, which make additional anchoring necessary.
Gleichartige Probleme treten auch bei anderen Oberbauformen auf. Aus der DE 195 00 443 AI, der DE 41 00 881 AI und der DE 44 39 894 AI ist es bekannt, das Schotterbett in einem in Längsrichtung der Gleisanlage verlaufenden Trog aus Beton anzuordnen, um eine gute Abstützung des Oberbaus auch bei hohen Fahrgeschwindigkeiten der Eisenbahnfahrzeuge zu gewährleisten. Um das bei Regen oder sonstigen Niederschlägen in den Trog gelangende Wasser stetig abführen zu können, sind in den Trog eine Vielzahl von Abflußleitungen integriert, durch die das Wasser aus dem Troginnenraum abfließen kann. Bei ansteigendem Grundwasserspiegel besteht auch hier die Gefahr, daß das Grundwasser durch die Abflußleitungen hindurch in den Troginnenraum eintritt und dort die Tragfähigkeit des Oberbaus beeinträchtigt oder diesen sogar beschädigt. Auch derartige Gleisanlagen werden deshalb mit den oben genannten Grundwasser-Betonwannen versehen, wodurch die bereits genannten Nachteile verbunden sind.Similar problems also occur with other superstructures. From DE 195 00 443 AI, DE 41 00 881 AI and DE 44 39 894 AI it is known to arrange the ballast bed in a longitudinal trough of the track system made of concrete in order to provide good support for the superstructure even at high speeds Ensure railway vehicles. In order to be able to continuously drain the water entering the trough during rain or other precipitation, a large number of drainage lines are integrated into the trough, through which the water can flow out of the interior of the trough. If the groundwater table rises, there is also the risk that the groundwater will enter the trough interior through the drain pipes and there impair the load-bearing capacity of the superstructure or even damage it. Such track systems are therefore provided with the above groundwater concrete tanks, which the Disadvantages already mentioned are connected.
Die EP 0 663 470 AI zeigt eine Gleisanlage mit einem U-förmigen Trog aus Beton, in dem das Schotterbett und die Gleise aufgenommen werden. Um während der Bauphase ein Ablaufen von Niederschlagswasser zu ermöglichen, sind in dem Trog beidseitig eine Vielzahl von Abflußöffnungen ausgebildet. Nach der Ausrichtung des Gleisrostes wird das Schotterbett in eine aushärtende Mörtelsuspension eingebunden, die den Troginnenraum vollständig ausfüllt. Um ein Abfließen der Mörtelsuspension zu vermeiden, müssen die Abflußöffnungen vor deren Einbringen mit Hilfe von Stopfen verschlossen werden. Nach der Fertigstellung der Gleisanlage ist ein monolitischer Lagerkörper für die Gleise gebildet, der Niederschlagswasser oberflächlich ableitet, ohne daß es sich in dem Trog ansammeln kann. Darüber hinaus verhindert die ausgehärtete Mörtelsuspension in Zusammenwirken mit den eingegossenen Stopfen, daß das Grundwasser in den Trog eindringt. Mit diesem Aufbau ist der Nachteil verbunden, daß das Ausgießen des gesamten Troginnenraums sehr aufwendig und teuer ist und nachträgliche Gleiskorrekturen erschwert.EP 0 663 470 AI shows a track system with a U-shaped trough made of concrete, in which the ballast bed and the tracks are received. In order to allow rainwater to run off during the construction phase, a large number of drainage openings are formed in the trough on both sides. After aligning the track grate, the ballast bed is integrated in a hardening mortar suspension that completely fills the interior of the trough. In order to prevent the mortar suspension from flowing off, the drain openings must be closed with plugs before they are introduced. After the completion of the track system, a monolithic bearing body is formed for the tracks, which drains rainwater superficially without it being able to accumulate in the trough. In addition, the hardened mortar suspension, in conjunction with the cast plugs, prevents the groundwater from penetrating into the trough. This construction has the disadvantage that pouring out the entire interior of the trough is very complex and expensive and makes subsequent track corrections difficult.
Der Erfindung liegt die Aufgabe zugrunde, eine Gleisanla- ge der eingangs genannten Art zu schaffen, bei der dasThe invention has for its object to provide a track system of the type mentioned, in which the
Eintreten von Grundwasser in den Trog zuverlässig und in einfacher Weise vermieden ist .Entry of groundwater in the trough is reliable and avoided in a simple manner.
Diese Aufgabe wird erfindungsgemäß bei einer Gleisanlage des o.g. Aufbaus dadurch gelöst, daß der Abflußleitung eine Verschlußeinrichtung zugeordnet ist, die ein Verschlußelement umfaßt, das zwischen einer geöffneten und einer die Abflußleitung verschließenden Stellung verstellbar ist, in der zumindest das Eindringen von Wasser durch die Abflußleitung in den Troginnenraum verhindert ist.This object is achieved in a track system of the above construction in that the drainage line is assigned a closure device which comprises a closure element which is adjustable between an open position and a position closing the drainage line, in which at least the penetration of water is prevented by the drain pipe into the interior of the trough.
Die Erfindung geht von der Überlegung aus, daß der der seitlichen Abstützung des Schotterbetts dienende Trog auch als Schutzwanne gegen aufsteigendes Grundwasser verwendet werden kann. Dabei ist weiterhin vorgesehen, das im Troginnenraum befindliche oder bei Niederschlägen eintretende Wasser bei normalem Grundwasserstand über die Abflußleitungen abzuführen. Der Eintritt von Wasser bei steigendem Grundwasserspiegel durch die Abflußleitungen hindurch wird jedoch im Bedarfsfall mittels des verstellbaren Verschlußelementes unterbunden.The invention is based on the consideration that the trough serving the lateral support of the ballast bed can also be used as a protective trough against rising groundwater. It is also provided that the water located in the interior of the trough or entering during precipitation is discharged via the drain pipes at a normal groundwater level. However, the entry of water through the drain pipes when the groundwater level rises is prevented if necessary by means of the adjustable closure element.
Die Randkappen sind bei der erfindungsgemäßen Gleisanlage selbstverständlich so hoch ausgebildet, daß das statistisch zu erwartende Grundwasser nicht über die Randkappen in den Trog hineinlaufen kann. Der Trog ist dabei in Höhe und Querschnitt so bemessen, daß er bei allen zu erwartenden Grundwasserständen auftriebssicher ohne Verankerungen auf dem Baugrund aufliegt.The edge caps are of course so high in the track system according to the invention that the statistically expected groundwater cannot run into the trough via the edge caps. The height and cross-section of the trough is dimensioned such that it rests against buoyancy at all expected groundwater levels without anchoring on the ground.
Da eine Absperrung der Abflußleitungen aufgrund steigenden Grundwassers relativ selten und gegebenenfalls in Jahrzehnten nur einmal notwendig ist, wird erfindungsge- mäß als Verschlußvorrichtung ein mechanisches Verschlußelement bevorzugt, das entweder manuell oder mit einer entsprechenden Antriebsvorrichtung wahlweise in eine geöffnete, die Abflußleitung freigebende Stellung oder in eine die Abflußleitung in beide Fließrichtungen verschließende Stellung gebracht werden kann. Als Verschlußvorrichtung hat sich eine verstellbar und insbesondere schwenkbar gelagerte Verschlußklappe bewährt. Alternativ kann auch ein über Zahnstange und Gewinde steuerbares Schiebeschott oder ein Rückschlagventil vorgesehen sein, das eine vom Troginnenraum nach außen gerichtete Wasserströmung zuläßt, eine entgegengesetzte Wasserströmung j edoch verhindert .Since a shutoff of the drain lines due to rising groundwater is relatively rare and possibly only once in decades, a mechanical closure element is preferred according to the invention as a closure device, either manually or with a corresponding drive device either in an open position that releases the drain line or in a position the drain line can be brought into a closed position in both flow directions. An adjustable and, in particular, pivotally mounted closure flap has proven to be a closure device. Alternatively, you can also control a rack and thread Sliding bulkhead or a check valve may be provided, which allows a water flow directed outwards from the interior of the trough, but prevents an opposite water flow.
In bevorzugter Ausgestaltung der Erfindung ist der Verschlußeinrichtung eine Detektoreinrichtung zugeordnet, mittels der der aktuelle Grundwasserstand in der Umgebung des Troges erfaßt wird. Wenn die Detektorvorrichtung ein Überschreiten eines vorbestimmten Grenzwertes des Grundwasserstandes feststellt, wirkt sie entweder direkt auf das Verschlußelement ein und verschließt die Abflußleitung, vorzugsweise ist jedoch vorgesehen, daß die Detektoreinrichtung ein Signal abgibt, das von einer Steuer- einheit empfangen wird, woraufhin die notwendige Maßnahme zur Aktivierung einer Antriebsvorrichtung zum Verschließen des Verschlußelementes oder eine Benachrichtigung von Servicepersonal erfolgt, das dann die Verschlußelemente in die geschlossene Stellung bringt.In a preferred embodiment of the invention, the closure device is assigned a detector device by means of which the current groundwater level in the vicinity of the trough is detected. If the detector device determines that a predetermined limit value of the groundwater level has been exceeded, it either acts directly on the closure element and closes the drain line, but it is preferably provided that the detector device emits a signal which is received by a control unit, whereupon the necessary measure to activate a drive device for closing the closure element or a notification from service personnel, which then brings the closure elements into the closed position.
Wenn das Verschlußelement die Abflußleitung über längere Zeit verschlossen hält, weil der Grundwasserspiegel auf einem hohen Niveau verbleibt, kann sich im Trog aus Niederschlägen resultierendes Wasser ansammeln. Um auch dieses im Bedarfsfall entfernen zu können, ist vorzugsweise vorgesehen, daß in dem Trog eine Entwässerungspumpe angeordnet ist, mittels der der Troginnenraum entwässert werden kann.If the closure element keeps the drain line closed for a long time because the groundwater level remains at a high level, water resulting from precipitation can accumulate in the trough. In order to be able to remove this if necessary, it is preferably provided that a drainage pump is arranged in the trough, by means of which the interior of the trough can be dewatered.
Für den erfindungsgemäßen Trog sind verschiedene Ausgestaltungen denkbar. Einerseits kann vorgesehen sein, jedes Gleis in einem eigenen Trog aufzunehmen, aus Kostengründen dürfte es jedoch günstiger sein, mehrere benachbarte Gleise in einem gemeinsamen Trog aufzunehmen. Insbesondere im letzteren Fall sollten auf beiden Seiten des Troges, d.h. in beiden Randkappen Abflußleitungen angeordnet sein, die jeweils mittels einer Verschlußeinrichtung absperrbar sind.Various configurations are conceivable for the trough according to the invention. On the one hand, provision can be made for each track to be accommodated in its own trough, but for cost reasons it should be cheaper to accommodate several adjacent tracks in a common trough. In the latter case in particular, drain lines should be arranged on both sides of the trough, ie in both edge caps, each of which can be shut off by means of a closure device.
Weitere Einzelheiten und Merkmale der Erfindung sind aus der folgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung ersichtlich. Es zeigen:Further details and features of the invention are apparent from the following description of exemplary embodiments with reference to the drawing. Show it:

Figur 4 die Gleisanlage gemäß Figur 3 bei hohem Grundwasserstand .Figure 4 shows the track system of Figure 3 with a high groundwater level.
Gemäß Figur 1 umfaßt eine Gleisanlage 10 für eine ein- gleisige Eisenbahnstrecke einen aus Beton gebildeten, sich vorzugsweise als kontinuierliches Band in Längsrichtung der Gleisanlage erstreckenden Trog 14, der eine auf einem Unterbau bzw. dem Erdboden 22 aufgelagerte Bodenplatte 15 und daran angebrachte seitliche, nach oben vorstehende Randkappen 16 umfaßt. Die Bodenplatte 15 bildet zusammen mit den Randkappen 16 den U-förmigen Trog 14 zur Aufnahme eines Schotterbettes 13 in dem Troginnenraum 24. Das Schotterbett 13 ist gegebenenfalls zur Bildung eines in sich stabilen Schotterkδrpers verklebt und lagert Schwellen 11 sowie Schienen 12 in bekannter Weise .According to FIG. 1, a track system 10 for a single-track railway line comprises a trough 14 formed of concrete, preferably extending as a continuous band in the longitudinal direction of the track system, which has a base plate 15 supported on a substructure or the ground 22 and attached to it laterally Edge caps 16 protruding above. The base plate 15 together with the edge caps 16 forms the U-shaped trough 14 for receiving a ballast bed 13 in the trough interior 24. The ballast bed 13 is optionally glued to form a stable ballast body and stores sleepers 11 and rails 12 in a known manner.
Am Fuß der gemäß Figur 1 rechten Randkappe 16 ist eine Abflußleitung 17 vorgesehen, durch die sich im Troginnenraum 24 bei Niederschlägen ansammelndes Wasser seitlich abfließen kann, wie durch den Pfeil W angedeutet ist. Zur Unterstützung des Abflusses kann die Bodenfläche des Troginnenraums 24 mit einer entsprechenden Querneigung versehen sein.At the foot of the right-hand edge cap 16 according to FIG. 1, a drain line 17 is provided, through which water which collects in the trough interior 24 during precipitation can flow off laterally, as indicated by the arrow W. To support the drain, the bottom surface of the trough interior 24 can be provided with a corresponding transverse incline.
Auf der Außenseite der Randkappe 16 ist eine schwenkbar gelagerte Verschlußklappe 18 vorgesehen, die aus der in Figur 1 gezeigten geöffneten Stellung in eine Schließ- Stellung gebracht werden kann, in der sie die Abflußleitung 17 vollständig verschließt.On the outside of the edge cap 16 there is a pivotably mounted closure flap 18 which can be brought from the open position shown in FIG. 1 to a closed position in which it completely closes the drain line 17.
Desweiteren ist im Troginnenraum 24 eine Entwässerungs- pumpe 19 vorgesehen, mittels der im Bedarfsfall Wasser aus dem Troginnenraum 24 über eine Leitung 23 abführbar ist .Furthermore, a drainage pump 19 is provided in the trough interior 24, by means of which water can be removed from the trough interior 24 via a line 23 if necessary.
Seitlich neben dem Trog 14 ist eine Detektorvorrichtung 20 installiert, die den Grundwasserstand GW in der Umge- bung des Troges 14 erfaßt und ein entsprechendes Signal über eine Leitung 21 an eine nicht dargestellte Steuereinheit abgibt .A detector device 20 is installed to the side of the trough 14, which detects the groundwater level GW in the area surrounding the trough 14 and emits a corresponding signal via a line 21 to a control unit (not shown).
Bei Normalbetrieb der Gleisanlage befindet sich die Verschlußklappe 18 in der geöffneten Stellung und dieDuring normal operation of the track system, the closure flap 18 is in the open position and
Entwässerungspumpe 19 ist deaktiviert, wobei das sich im Troginnenraum 24 ansammelnde Wasser durch die Abflußleitung in Form eines Freispiegelabflusses abströmen kann. Wenn die Detektoreinrichtung 20 ein Ansteigen des Grund- Wasserstandes GW über einen vorbestimmten Grenzwert feststellt, wird von der Steuereinheit veranlaßt, daß die Verschlußklappe 18 in die geschlossene Stellung gebracht wird, so daß der Eintritt von Grundwasser in den Trog- innenraum 24 vermieden ist, wie es in Figur 2 dargestellt ist. Dabei kann die Entwässerung des Troginnenraums 24 von eventuellen Niederschlägen durch Aktivierung der Entwässerungspumpe 19 erfolgen.Drainage pump 19 is deactivated, the water collecting in the interior of the trough 24 being able to flow out through the drain line in the form of a free-level drain. If the detector device 20 detects an increase in the basic Detects water level GW above a predetermined limit value, the control unit causes the closure flap 18 to be brought into the closed position, so that the entry of groundwater into the interior of the trough 24 is avoided, as shown in FIG. The trough interior 24 can be drained of any precipitation by activating the dewatering pump 19.
Die Figuren 3 und 4 zeigen ein alternatives Ausführungs- beispiel der erfindungsgemäßen Gleisanlage, das sich von dem Beispiel gemäß den Figuren 1 und 2 lediglich dadurch unterscheidet, daß nunmehr zwei nebeneinander verlaufende Gleise mit ihrem Schotterbett 13 in einem gemeinsamen Trog 14a ausgebildet sind. In beiden Randkappen 16 ist jeweils eine Abflußleitung 17 ausgebildet, die mit einer zugeordneten Verschlußklappe 18 in genannter Weise verschließbar ist. Zur Erleichterung des Abflusses aus dem Troginnenraum 24 ist dessen Bodenfläche mit einer dach- förmigen Querneigung ausgestaltet und an deren tiefsten Punkt ist jeweils eine Entwässerungspumpe 19 angeordnet. FIGS. 3 and 4 show an alternative embodiment of the track system according to the invention, which differs from the example according to FIGS. 1 and 2 only in that two tracks running next to one another are now formed with their ballast bed 13 in a common trough 14a. A drain line 17 is formed in each of the two edge caps 16 and can be closed in the aforementioned manner with an associated closure flap 18. In order to facilitate the outflow from the interior of the trough 24, the bottom surface thereof is designed with a roof-shaped cross slope and a drainage pump 19 is arranged at the lowest point of each.
