Abstract

In this device for capturing harmful substances with troughs (1) laid upon the roadbed (2) or other supports (3), with such a trough (1), the edge of the trough lying on the side of the trough (1) towards a rail (4) is constructed as a sealing edge (5) in such a way that it extends beneath the rail head (7). In order to stabilise the sealing edges (5) it is possible to provide supports (10) above which the sealing edges (5) can be supported on the rail foot (9). Securing webs (15) are provided to secure troughs (1.1) arranged at the side of a pair of rails to prevent the lateral slip of a trough (1.1). For the arrangement (1.2) between two rails (4) of a pair of rails, these troughs (1.2) are fitted with sealing edges (5) and fitted between the rails (4) in such a way that the sealing edges (5) are supported on either side of the rail webs (11).

Description

Die Erfindung betrifft eine Vorrichtung zum Auffangen von flüssigen und/oder körnigen Schadstoffen im Schienenbereich von Schienenfahrzeugen mit Wannen, die zwischen die Schienen auf die Schienenbettung oder sonstige Auflagen aufgelegt sind, wobei eine Wanne auf ihrer der Schiene zugewandten Seite einen als Dichtungsrand ausgebildeten Wannenrand aufweist, der unter den Schienenkopf greift.The invention relates to a device for collecting liquid and / or granular pollutants in the rail area of rail vehicles with trays, which are placed between the rails on the rail bedding or other supports, a tray having a tub edge designed as a sealing edge on its side facing the rail. that reaches under the rail head.

Beim Betanken, Befüllen oder Umfüllen von Schadstoffen oder schadstoffhaltigen Materialien an Umfüllstationen, Lagerstätten oder Beschickungsanlagen für Industrie, aber auch an Tankstellen, Lokabstellplätzen und Waschplätzen für schienengebundene Fahrzeuge besteht die Gefahr, daß ein Teil der Schadstoffe direkt oder mittelbar über das Regenwasser in das Erdreich gelangt und dabei Verunreinigungen des Erdreiches und des Grundwassers hervorruft, wodurch ökologisch nicht vertretbare Folgeerscheinungen auftreten.When refueling, filling or decanting pollutants or materials containing pollutants at transfer stations, storage facilities or loading systems for industry, but also at petrol stations, locomotive parking spaces and washing areas for rail-bound vehicles, there is a risk that some of the pollutants will get into the soil directly or indirectly via the rainwater and thereby contaminates the soil and the groundwater, which causes ecologically unacceptable consequences.

Zur Lösung des Problemes ist es aus der DE-OS 35 11 552 bekannt, im Schienenbereich von Schienenfahrzeugen Wannen auf die Schienenbettung oder sonstige Auflagen aufzulegen. Zur Abdichtung einer derartigen Wanne gegenüber der Schiene ist ein einseitig gehaltenes Abdeckprofil vorgesehen, dessen freie Seite den hochgezogenen benachbarten Wannenrand übergreift. Die Wanne selbst ist zweigeteilt ausgeführt, wobei beide Wannenteile zu einer Querrinne hin geneigt sind und an dieser Querrinne eine übergreifende Abkantung aufweisen. Die übrigen drei Seiten jedes Wannenteiles weisen Begrenzungswände auf, die als Aufkantungen ausgeführt sind. Das Abdeckprofil ist vom Schienensteg zum benachbarten Wannenrand hin geneigt ausgebildet.To solve the problem, it is known from DE-OS 35 11 552 to place tubs on the rail bedding or other conditions in the rail area of rail vehicles. To seal such a tub from the rail, a cover profile is provided on one side, the free side of which engages over the raised adjacent tub rim. The tub itself is designed in two parts, with both tub parts being inclined towards and on a transverse channel Cross gutter have an overlapping bend. The remaining three sides of each tub part have boundary walls that are designed as upstands. The cover profile is inclined from the rail web to the adjacent tub edge.

Für die Befestigung des Abdeckprofils am Schienensteg ist es nach dieser Offenlegungsschrift bekannt, das Abdeckprofil entweder am Schienensteg anzuschrauben oder mittels geeigneter Vorrichtungen an diesem festzuklemmen.For the attachment of the cover profile to the rail web, it is known from this laid-open document to either screw the cover profile onto the rail web or to clamp it onto it by means of suitable devices.

Nachteilig ist bei dieser Lösung der hohe Montageaufwand, der daraus resultiert, daß die Befestigung der Abdeckprofile von der Unterseite erfolgen muß, was zusätzlich dadurch erschwert wird, daß die Abdeckprofile funktionsbedingt nach unten geneigt sind. Erst wenn diese Montage vollständig abgeschlossen ist, können die Wannen selbst eingebracht werden, was dadurch erschwert wird, daß die Begrenzungswände der Wannenteile unter die Abdeckprofile zu bringen sind.A disadvantage of this solution is the high installation effort, which results from the fact that the cover profiles must be attached from the underside, which is further complicated by the fact that the cover profiles are inclined downward due to their function. Only when this assembly is completely completed, the tubs can be inserted themselves, which is made more difficult by the fact that the boundary walls of the tub parts have to be brought under the cover profiles.

Außerdem ist die Befestigung der Abdeckprofile mit Nachteilen behaftet, da Klemmvorrichtungen eine Vielzahl von Bauteilen erfordern oder aber das direkte Anschrauben der Abdeckprofile an die Schienenstege das Einbringen von Schraublöchern erfordert, wodurch die Tragfähigkeit der Schienen vermindert wird.In addition, the attachment of the cover profiles has disadvantages, since clamping devices require a large number of components, or screwing the cover profiles directly onto the rail webs requires the introduction of screw holes, thereby reducing the load-bearing capacity of the rails.

Weiterhin ist aus der US-Patentschrift 3,773,255 eine Lösung der gattungsgemäßen Art bekannt, die Wannen aufweist, die auf die Schienenbettung oder sonstige Auflagen aufgelegt sind. An einer der Schiene zugewandten Seite weisen diese Wannen einen als Dichtungsrand ausgebildeten Rand auf, der unter den Schienenkopf greift. Der Dichtungsrand ist zur sicheren Abdichtung mit einer Profildichtung versehen, die die Differenzen zwischen dem Dichtungsrand und der Schiene ausgleicht.Furthermore, a solution of the generic type is known from US Pat. No. 3,773,255, which has tubs which are placed on the rail bedding or other supports. On one side facing the rail, these troughs have an edge designed as a sealing edge, which engages under the rail head. For a secure seal, the sealing edge is provided with a profile seal that compensates for the differences between the sealing edge and the rail.

Der Dichtungsrand ist von dem Wannenboden in Richtung zu der Schiene im wesentlichen schräg ausgebildet.The sealing edge is formed essentially obliquely from the trough bottom in the direction of the rail.

Die Wannen reichen in der quer zur Schienenlängserstreckung liegenden Richtung in Annäherung bis zur Hälfte des Schienenzwischenraumes. Dort zeigen sie eine nach oben gerichtete Aufkantung. Diese Aufkantung dient einerseits der Verhinderung des Herausfließens von Schadstoffen und andererseits der Befestigung der Wannen.In the direction lying transversely to the longitudinal direction of the rail, the troughs extend approximately to half of the space between the rails. There they show an upward edging. This upstand serves on the one hand to prevent pollutants from flowing out and on the other hand to secure the tubs.

Die Wannen sind mittels Profilstücken, die die Wannen umgreifen und die ihrerseits auf die Schienenschwellen aufgeschraubt werden, befestigt. Auf diesen Profilstücken stützt sich ein Laufrost ab, das sein seitliches Widerlager auf den schrägen Teilen des Dichtungsrandes findet.The tubs are fastened by means of profile pieces, which encompass the tubs and which in turn are screwed onto the rail sleepers. A running grate is supported on these profile pieces, which finds its lateral abutment on the oblique parts of the sealing edge.

Diese Lösung zeigt mehrere Nachteile. So ist es einerseits nicht möglich, diese Ausführung bei Betonschwellen einzusetzen, da dabei keine Verschraubung der Profilstücke erfolgen kann. Sie ist also allein auf den Einsatz bei Holzschwellen beschränkt. Außerdem liegen die Laufroste konstruktionsbedingt weit unter den Schienenköpfen, so daß diese aus der Ebene der Laufroste herausragen, worin eine erhebliche Stolpergefahr zu sehen ist. Somit dürfte diese Lösung mit Arbeitsschutzvorschriften in Kollision geraten.This solution has several disadvantages. On the one hand, it is not possible to use this version with concrete sleepers, since the profile pieces cannot be screwed together. It is therefore limited to use with wooden sleepers. In addition, due to their construction, the gratings are located far below the rail heads, so that they protrude from the level of the gratings, which is a considerable risk of tripping. This solution should therefore collide with occupational safety regulations.

In der Praxis sind die Schienen in einem Verhältnis von 1 : 40 aufeinander zu geneigt. Bei der Belastung werden die Schienen entgegen ihrer Neigung nach außen gebogen. Dieses Biegeverhalten bedingt durch die starre Befestigung der Wannen auf den Schwellen ein Lösen der Dichtung von der Schiene, wodurch keine Dichtheit mehr gewährleistet werden kann.In practice, the rails are inclined at a ratio of 1:40. When loaded, the rails are bent outwards against their inclination. This bending behavior requires that the troughs are rigidly attached to the sleepers and that the seal is detached from the rail, which means that tightness can no longer be guaranteed.

Letztendlich stellt sich die Montage eines solchen Auffangsystems recht aufwendig dar, da eine Vielzahl von paßgenauen Schraubverbindungen herzustellen ist. Außerdem ist die gesamte Anlage, beispielsweise bei Arbeiten am Unterbau, mit dem gleichen Aufwand vollkommen zu demontieren.Ultimately, the assembly of such a collection system is quite complex since a large number of precisely fitting screw connections have to be produced. In addition, the entire system, for example when working on the substructure, can be completely dismantled with the same effort.

Daher besteht die Aufgabe der Erfindung darin, eine Vorrichtung zum Auffangen von flüssigen und/oder körnigen Schadstoffen zu schaffen, die im Schienenbereich von Schienenfahrzeugen zuverlässig und mit geringem Aufwand eingesetzt werden kann, wodurch eine schnelle und kostengünstige Montage und Demontage ermöglicht wird und die eine sichere Dichtung auch bei verschiedenen Belastungszuständen ermöglicht.The object of the invention is therefore to provide a device for collecting liquid and / or granular pollutants to create, which can be used reliably and with little effort in the rail area of rail vehicles, which enables fast and inexpensive assembly and disassembly and which enables a secure seal even under various load conditions.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Wanne an den beiden gegenüber- und in Schienenlängsrichtung liegenden Seiten als Dichtungsrand ausgebildet ist und daß die Wanne eine solche Breite aufweist, daß sie zur alleinigen Befestigung derart straff zwischen den Schienen liegt, daß die Dichtungsränder kraftschlüssig an den Schienen anliegen.This object is achieved according to the invention in that the trough is formed on the two opposite and in the longitudinal direction of the sides as a sealing edge and that the trough has such a width that it is so tight for sole attachment between the rails that the sealing edges Apply frictionally to the rails.

Die Aufgabe der Erfindung wird auch dadurch gelöst, daß die der Schiene abgewandte, in Schienenlängsrichtung verlaufende Seite der seitlich zum Schienenpaar angeordneten Wanne nach oben abgekantet ist und daß quer zur Längserstreckung der Schiene Haltestege vorgesehen sind, die den Schienenfuß auf der wannenabgewandten Seite zumindest teilweise umgreifen. Diese Haltestege erstrecken sich unter dem Schienenfuß hindurch, unter die Wanne, bis zu dem der Schiene abgewandten Wannenrand. Mit diesem Wannenrand sind die Haltestege formschlüssig verbunden. Dabei ist der Haltesteg im Verhältnis zu der Wanne so bemessen, daß die Wanne als alleinige Befestigung straff in der Halterung sitzt und der Dichtungsrand kraftschlüssig gegen die Schiene gedrückt wird.The object of the invention is also achieved in that the side of the trough which is arranged laterally to the rail pair and which faces away from the rail is bent upwards and that retaining webs are provided transversely to the longitudinal extent of the rail, which at least partially encompass the rail foot on the side facing away from the trough . These retaining webs extend under the rail foot, under the tub, to the tub rim facing away from the rail. The retaining webs are positively connected to this tub rim. The retaining web is dimensioned in relation to the tub so that the tub sits tightly in the holder as the sole attachment and the sealing edge is pressed non-positively against the rail.

In einer günstigen Ausgestaltung der Erfindung sind Abstützungen vorgesehen, die zwischen der Unterseite des Dichtungsrandes und der Oberseite des Schienenfußes angeordnet sind.In a favorable embodiment of the invention, supports are provided which are arranged between the underside of the sealing edge and the top of the rail foot.

Dabei ist es günstig, die Abstützungen als Holzleisten auszubilden.It is advantageous to design the supports as wooden strips.

Eine besonders günstige Gestaltung der Abstützungen sieht vor, daß diese einen keilförmigen Querschnitt aufweisen.A particularly favorable design of the supports provides that they have a wedge-shaped cross section.

Die erfindungsgemäße Lösung mit Haltestegen kann eine besonders günstige Ausgestaltung dadurch erfahren, daß die Haltestege an der Seite, an der sie den Schienenfuß zumindest teilweise umgreifen, eine nach oben gerichtete Lasche zur Halterung der Abstützung auf der einen Schienenseite aufweisen. Auf der Seite des Schienenfußes, der der Wanne zugewandt ist, sind Halteelemente vorgesehen, die mit dem Haltesteg verbunden sind. Diese Haltestege umgreifen den Schienenfuß zumindest teilweise. Sie weisen ebenfalls eine nach oben gerichtete Lasche (17) zur Halterung der Abstützung (10) auf der anderen Schienenseite auf.The solution according to the invention with retaining webs can experience a particularly favorable configuration in that the retaining webs on the side on which they at least partially encompass the rail foot, have an upwardly directed tab for holding the support on one side of the rail. Holding elements are provided on the side of the rail foot that faces the trough, which are connected to the holding web. These holding bars at least partially encompass the rail foot. They also have an upward tab (17) for holding the support (10) on the other side of the rail.

Eine besonders günstige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die Wannen rechteckig ausgeführt sind, wobei eine quer zur Schienenlängsrichtung liegende Seite der Wannen nach oben und die andere nach unten abgekantet ist. Die nach unten abgekantete Seite liegt in horizontaler Ebene gegenüber der nach oben abgekanteten Seite stets tiefer und greift über die nach oben abgekantete Seite einer benachbarten Wanne oder ragt über den Rand einer Querrinne zur Schadstoffableitung.A particularly favorable embodiment of the invention is characterized in that the troughs are rectangular, one side of the troughs lying transversely to the longitudinal direction of the rail being bent upwards and the other downward. The side that is bent downwards is always lower in the horizontal plane compared to the side that is bent upwards and reaches over the side of an adjacent trough that is bent upward or protrudes over the edge of a transverse channel to discharge pollutants.

Eine besonders günstige Ausgestaltung sieht dabei vor, daß mehrere Wannen derart hintereinander angeordnet sind, daß die nach oben gekanteten Seiten zweier Wannen aufeinander zu weisen und daß eine diese beiden Seiten übergreifende Abdekkung vorgesehen ist.A particularly favorable embodiment provides that a plurality of tubs are arranged one behind the other in such a way that the upwardly bent sides of two tubs point towards one another and that a cover is provided which overlaps these two sides.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß auf der Oberseite der Wannenränder Halteelemente für Laufroste angeordnet sind.Another embodiment of the invention provides that holding elements for gratings are arranged on the top of the tub edges.

Wie aus den Zeichnungen erkennbar ist, besteht die erfindungsgemäße Vorrichtung zum Auffangen von flüssigen und/oder körnigen Schadstoffen im Schienenbereich aus Wannen 1, die sowohl auf der Schienenschotterbettung 2 als auch auf den im Abstand angeordneten Schwellen 3 aufgelegt sind.As can be seen from the drawings, the device according to the invention for collecting liquid and / or granular pollutants in the rail area consists of troughs 1 which are placed both on the rail ballast bed 2 and on the sleepers 3 arranged at a distance.

Wie aus Fig. 1 und Fig. 2 ersichtlich ist, sind die Wannenränder, die einer Schiene 4 zugewandt sind, als Dichtungsränder 5 ausgebildet. Die Dichtungsränder 5 besitzen einen vom Wannenboden 6 gerade nach oben gerichteten Teil 5.1, an den sich ein im wesentlichen schräg nach oben gerichteter Teil 5.2 anschließt.As can be seen from FIGS. 1 and 2, the tub edges, which face a rail 4, are designed as sealing edges 5. The sealing edges 5 have a part 5.1 which is directed straight upwards from the tub base 6 and which is followed by a part 5.2 which is directed essentially obliquely upwards.

Die äußere Kante des Teiles 5.2 des Dichtungsrandes 5 greift unter den Schienenkopf 7. Zur Abdichtung zwischen der Schiene und dem Dichtungsrand ist eine Dichtung 8 vorgesehen. Diese Dichtung 8 kann als Profilmaterial ausgebildet sein oder durch Eindrücken eines aushärtbaren Dichtungsmittels erzeugt werden. Zweckmäßigerweise finden solche Materialien Anwendung, die von den auftretenden Schadstoffen nicht angegriffen werden.The outer edge of part 5.2 of the sealing edge 5 engages under the rail head 7. For sealing between a seal 8 is provided on the rail and the sealing edge. This seal 8 can be designed as a profile material or can be produced by pressing in a hardenable sealant. Such materials are expediently used which are not attacked by the pollutants which occur.

Zwischen der Unterseite des Teiles 5.2 des Dichtungsrandes 5 und der Oberseite des Schienenfußes 9 sind Hartholzleisten 10 als Abstützungen eingebracht, die einen keilförmigen Querschnitt aufweisen. Durch diesen keilförmigen Querschnitt wird einerseits die Auflagefläche vergrößert und andererseits erzielt, daß die Hartholzleisten 10 stets in Richtung zum Schienensteg 11 hin gedrückt werden.Hardwood strips 10 are inserted as supports between the underside of part 5.2 of the sealing edge 5 and the top of the rail foot 9, which have a wedge-shaped cross section. This wedge-shaped cross section on the one hand increases the contact surface and on the other hand ensures that the hardwood strips 10 are always pressed in the direction of the rail web 11.

Auf der Oberseite der Wannenränder sind Halteelemente 12 befestigt, in die Laufroste 13 eingelegt sind. Diese Halteelemente 12 dienen einerseits der Auflage der Laufroste 13 und verhindern gleichzeitig deren seitliches Wegrutschen.On the top of the tub edges, holding elements 12 are attached, in which the gratings 13 are inserted. On the one hand, these holding elements 12 serve to support the gratings 13 and at the same time prevent them from slipping sideways.

Zwischen den abstandsweise im Bereich der Schwellen 3 angeordneten Schienenbefestigungen 14 sind Haltestege 15 vorgesehen, die in Fig. 2 ersichtlich sind. Diese Haltestege 15 dienen der Befestigung der seitlich zum Schienenpaar angeordneten Wannen 1.1. Diese Haltestege 15 sind quer zur Längserstreckung der Schiene 4 angeordnet und umgreifen den Schienenfuß 9 auf der wannenabgewandten Seite teilweise und erstrecken sich unter dem Schienenfuß hindurch unter der Wanne 1.1 bis zu der der Schiene abgewandten Seite der Wanne 1.1 und umgreifen diese Seite formschlüssig mit einer nach oben gerichteten Aufkantung 16. Die Seite des Haltesteges 15, die den Schienenfuß 9 teilweise umgreift, weist eine nach oben gerichtete Lasche 17 auf, mit der die Hartholzleiste 10 zusätzlich in ihrer Lage gehalten wird. Zur zusätzlichen Halterung der Hartholzleiste 10 auf der anderen Schienenseite ist ein Halteelement 18 mit dem Haltesteg 15 verbunden, welches den Schienenfuß 9 ebenfalls teilweise umgreift und ebenfalls eine nach oben gerichtete Lasche 17 besitzt, an der die Hartholzleiste 10 anliegt.Retaining webs 15, which can be seen in FIG. 2, are provided between the rail fastenings 14 arranged at a distance in the area of the sleepers 3. These holding webs 15 serve to fasten the troughs 1.1 arranged laterally to the pair of rails. These retaining webs 15 are arranged transversely to the longitudinal extent of the rail 4 and partially encompass the rail foot 9 on the side facing away from the tub and extend under the rail foot under the tub 1.1 to the side of the tub 1.1 facing away from the rail and encompass this side with a positive fit upward edging 16. The side of the holding web 15, which partially engages around the rail foot 9, has an upward tab 17 with which the hardwood strip 10 is additionally held in position. For additional mounting of the hardwood strip 10 on the other side of the rail a holding element 18 is connected to the holding web 15, which also partially surrounds the rail foot 9 and also has an upwardly directed tab 17 against which the hardwood strip 10 rests.

Die Bemessung des Haltesteges 15 im Verhältnis zur Wanne 1.1 ist so gewählt, daß die Wanne 1.1 straff in der Halterung 15 sitzt und somit der Dichtungsrand 5 kraftschlüssig gegen die Schiene 4 gedrückt wird.The dimensioning of the retaining web 15 in relation to the tub 1.1 is chosen so that the tub 1.1 sits tightly in the holder 15 and thus the sealing edge 5 is pressed non-positively against the rail 4.

Wie aus Fig. 4 und 5 ersichtlich ist, sind die Wannen 1 rechteckig ausgeführt. Dabei ist jeweils eine quer zur Längsrichtung der Schiene 4 liegende Seite 19 der Wannen 1 nach oben und die andere, gegenüberliegende Seite 20 nach unten abgekantet. Die nach unten abgekanteten Seiten 19 liegen dabei in horizontaler Ebene stets tiefer als die nach oben abgekanteten Seiten.As can be seen from FIGS. 4 and 5, the tubs 1 are rectangular. In this case, one side 19 of the troughs 1 lying transversely to the longitudinal direction of the rail 4 is bent upwards and the other, opposite side 20 is bent downwards. The sides 19 bent downwards are always lower in the horizontal plane than the sides bent upwards.

In der Ausführungsform nach Fig. 4 und 5 ragt jede nach unten abgekantete Seite 20 einer Wanne 1 über eine Querrinne 21 zur Schadstoffableitung.In the embodiment according to FIGS. 4 and 5, each side 20 of a trough 1 which is bent downwards projects over a transverse channel 21 for the discharge of pollutants.

Fig. 6 zeigt eine andere Ausführungsform der erfindungsgemäßen Vorrichtung, bei der mehrere Wannen 1 derart hintereinander angeordnet sind, daß eine nach unten abgekantete Seite 20 einer Wanne 1 über die nach oben abgekantete Seite 19 einer benachbarten Wanne 1 greift. Erst die nach unten abgekantete Seite 20 der am tiefsten liegenden Wanne 1 greift über die Querrinne 21 und dient damit der Schadstoffableitung auch der benachbarten Wannen 1.Fig. 6 shows another embodiment of the device according to the invention, in which a plurality of tubs 1 are arranged one behind the other in such a way that a downwardly bent side 20 of a tub 1 engages over the upwardly bent side 19 of an adjacent tub 1. Only the downwardly bent side 20 of the deepest tub 1 reaches over the transverse channel 21 and thus also serves to discharge pollutants from the adjacent tubs 1.

Diese Wannengruppen, wie auch die Wannen in Fig. 4 und 5, sind derart hintereinander angeordnet, daß sie wechselweise entgegengesetzte Neigungswinkel aufweisen, so daß die nach oben gekanteten Seiten 19 zweier benachbarter Wannen 1 aufeinander zu weisen. An diesen Stellen sind übergreifende Abdeckungen 22 vorgesehen, die die beiden nach oben gekanteten Seiten 19 einerseits zusammendrücken und andererseits eine zusätzliche Abdichtung bieten.These tub groups, as well as the tubs in FIGS. 4 and 5, are arranged one behind the other in such a way that they have mutually opposite angles of inclination, so that the sides 19 of two adjacent tubs 1 which are bent upward point towards one another. At these points overlapping covers 22 are provided, which Compress both sides 19 folded upwards on the one hand and offer an additional seal on the other hand.

In Fig. 3 ist ein Querschnitt durch die gesamte erfindungsgemäße Vorrichtung dargestellt. Daraus ist ersichtlich, daß bei den Wannen 1.2., die zwischen zwei Schienen 4 eingelegt sind, der Wannenrand an den beiden gegenüber in der Längsrichtung der Schienen 4 liegenden Seiten als Dichtungsrand 5 ausgebildet ist. Die Größe dieser Wannen 1.2 wurde so gewählt, daß sie straff zwischen den beiden Schienen 4 liegen, so daß die Dichtungsränder 5 kraftschlüssig an den Schienen 4 anliegen.3 shows a cross section through the entire device according to the invention. From this it can be seen that in the tubs 1.2 which are inserted between two rails 4, the tub edge is designed as a sealing edge 5 on the two sides lying opposite in the longitudinal direction of the rails 4. The size of these tubs 1.2 was chosen so that they lie taut between the two rails 4, so that the sealing edges 5 rest non-positively on the rails 4.

Bei den Wannen 1.1., die seitlich zum Schienenpaar angeordnet sind, ist der der Schiene 4 zugewandte Wannenrand als Dichtungsrand 5 ausgebildet und die andere, in Längsrichtung der Schiene 4 laufende Seite 23, nach oben abgekantet.In the tubs 1.1., Which are arranged laterally to the pair of rails, the tub edge facing the rail 4 is designed as a sealing edge 5 and the other side 23, which runs in the longitudinal direction of the rail 4, is bent upwards.
