Description

Die Erfindung betrifft eine Lärmschutzeinrichtung für mehrgleisige Eisenbahnstrecken mit einer Mittelwand zwischen zwei benachbarten Gleisen.The invention relates to a noise protection device for multi-track railway lines with a central wall between two adjacent tracks.

Ein Schutz vor dem Lärm des Schienenverkehrs ist bei mehrgleisigen Eisenbahnstrecken ohne derartige Mittel­wände kaum zu erreichen. Eine Schallschutzwand muß mög­lichst nahe an der Schallquelle, das sind vor allem die Laufräder der Eisenbahn, angeordnet werden, um bei ver­tretbarer Bauhöhe wirksam zu sein. Allein an der bzw. den Außenseiten einer mehrgleisigen Eisenbahnstrecke angeord­nete Schallschutzwände sind von den Laufrädern des oder der inneren Gleise(s) zu weit entfernt. Anderseits stel­len Mittelwände ein besonderes Hindernis für die Dienst­wege, z.B. Rangierwege, des Bahnpersonals dar. Außerdem sind Mittelwände ein Hindernis bei Oberbau-Baustellen.Protection from the noise of rail traffic is hardly achievable on multi-track railway lines without such middle walls. A soundproof wall must be placed as close as possible to the sound source, in particular the railway wheels, in order to be effective with a reasonable overall height. Soundproof walls arranged only on the outside of a multi-track railway line are too far away from the wheels of the inner track (s). On the other hand, middle walls pose a particular obstacle to official channels, e.g. Shunting paths, the train staff. In addition, middle walls are an obstacle at superstructure construction sites.

Der Erfindung liegt die Aufgabe zugrunde, eine Lärm­schutzeinrichtung mit einer Mittelwand zwischen be­nachbarten Gleisen bereitzustellen, die weniger hin­derlich und nicht gefährlich für das Bahnpersonal ist.The invention has for its object to provide a noise protection device with a central wall between adjacent tracks, which is less cumbersome and not dangerous for the train staff.

Die Erfindung besteht bei einer Lärmschutzeinrichtung der eingangs genannten Art darin, daß die Mittelwand unter die Randbereiche der beiden benachbarten Lichtraumprofile ragt und gegen Querverschieben gesichert ist.In the case of a noise protection device of the type mentioned at the outset, the invention consists in the central wall protruding below the edge regions of the two adjacent clearance profiles and being secured against transverse displacement.

Die Erfindung basiert auf der Erkenntnis, daß bei Eisen­bahnen Lärm in erster Linie im Bereich der Schienen und Räder entsteht. Wird der Schallaustritt aus diesem Be­reich behindert - dies gelingt mit geringem Aufwand mit Hilfe der erfindungsgemäßen Mittelwand, dann ist ein gu­ter Lärmschutz gewährleistet. Durch die erfindungsgemäße Mittelwand wird der Entstehungsort von Lärm quasi gegen­über dem fahrenden Zug abgedichtet, so daß der Lärm nicht oder nur gedämpft austreten kann.The invention is based on the finding that railroad noise primarily arises in the area of rails and wheels. If the sound exit from this area is hindered - this can be achieved with little effort using the central wall according to the invention, then good noise protection is ensured. By means of the central wall according to the invention, the point of origin of noise is virtually sealed off from the moving train, so that the noise cannot emerge or can only emerge in a dampened manner.

Schallschutzeinrichtungen mit in ihrem nach innen abge­winkelten unteren Abschnitt unter den Randbereich des Lichtraumprofils reichenden Wänden bzw. mit vollständig unter diesem Randbereich angeordneten niedrigen Mauern sind in der AT-PS 372 435 bzw. der EP-PS 85 765 bereits vorgeschlagen worden. Bei diesen bekannten Einrichtungen handelt es sich aber um übliche schmale Mauern oder Wände die als Mittelwände zwischen zwei benachbarten Gleisen hinderlich für die Bahnunterhaltung und für das Bahnper­sonal gefährlich sind. Derartige Mittelwände können die bekannte Erfindung daher auch nicht nahelegen.Soundproofing devices with walls in their inwardly angled lower section below the edge area of the clearance profile or with low walls arranged completely under this edge area have already been proposed in AT-PS 372 435 and EP-PS 85 765. These known devices are, however, customary narrow walls or walls which, as the middle walls between two adjacent tracks, are a hindrance to railroad maintenance and train staff. Such middle walls can therefore not suggest the known invention.

In einer bevorzugten Ausführungsform der Erfindung ist die Mittelwand in Form eines bahnsteigähnlichen, begeh­baren Steges ausgebildet. Diese Ausführungsform ergibt neben dem erhöhten Schallschutz auch den Vorteil, daß die Wand ohne weiteres auch in Längsrichtung begehbar ist.In a preferred embodiment of the invention, the central wall is designed in the form of a platform-like, walkable web. In addition to the increased sound insulation, this embodiment also has the advantage that the wall can also be easily walked in the longitudinal direction.

Der erfindungsgemäß vorgesehene begehbare Bahnsteig kann sich dadurch auszeichnen, daß die Mittelwand in Elemente gleicher Länge unterteilt ist, die auf einem Untergrund, z.B. auf dem Schotterbett, oder dort vorgesehener Platten nivelliert und abhebbar angeordnet sind.The walk-on platform provided according to the invention can be characterized in that the central wall is divided into elements of the same length, which are placed on a base, e.g. on the ballast bed, or plates provided there are leveled and arranged to be liftable.

Ein zwischen den Gleisen angeordneter derartig niedriger "Bahnsteig" ist ohne Schwierigkeiten ersteigbar; aus Si­cherheitsgründen kann es aber trotzdem im Rahmen der Er­findung vorgesehen sein, wenn an der Mittelwand, auf ei­ner und/oder beiden ihrer Längsseiten, wenigstens ab­schnittweise eine Stufe angebaut ist.Such a low "platform" arranged between the tracks can be climbed without difficulty; for safety reasons it can nevertheless be provided within the scope of the invention if a step is attached to the central wall, on one and / or both of its longitudinal sides, at least in sections.

Vorteilhaft ist die Mittelwand in Elemente gleicher Länge unterteilt, die im Stoßbereich zur Vermeidung einer durchgehenden Fuge abgestuft ineinandergreifen. Die er­findungsgemäße Lärmschutzeinrichtung kann somit einfach errichtet und nötigenfalls wieder abgebaut werden.The middle wall is advantageously divided into elements of the same length, which interlock in the joint area in order to avoid a continuous joint. The noise protection device according to the invention can thus be easily installed and, if necessary, dismantled again.

Um Sicherheit gegen ein Querverschieben der Mittelwand bei seitlichem Kraftangriff zu gewährleisten und eine lagerichtige Montage sicherzustellen, können erfindungs­gemäß im Untergrund entlang der Mittelebene zwischen den Gleisen einzelne Pfähle verankert sein, die in eine Öffnung, vorzugsweise eine Längsnut, in der Mitte der Unterseite des Bahnsteiges eingreifen.For security against the middle wall being moved To ensure lateral force application and ensure correct installation, according to the invention, individual piles can be anchored in the underground along the central plane between the tracks, which engage in an opening, preferably a longitudinal groove, in the middle of the underside of the platform.

Zur besseren Schallabsorption kann die Mittelwand aus Vollmaterial, z.B. Schwerbeton, bestehen.For better sound absorption, the middle wall made of solid material, e.g. Heavy concrete.

Zur Gewichts- und Materialersparnis ist es aber auch möglich, daß die Mittelwand mit einem kamm- oder E-förmigen Querschnitt ausgebildet ist.To save weight and material, it is also possible that the central wall is formed with a comb or E-shaped cross section.

Die Oberfläche der erfindungsgemäß vorgesehenen Mittel­wand kann mit Vorteil in bekannter Weise zur Verbesserung des Schallschluckvermögens gestaltet sein.The surface of the center wall provided according to the invention can advantageously be designed in a known manner to improve the sound absorption capacity.

Um auch das einseitige Entfernen der erfindungsgemäßen Mittelwand zu ermöglichen, kann vorgesehen sein, daß die Mittelwand aus zwei vorzugsweise spiegelsymmetrisch aus­gebildeten Teilen besteht, die im Bereich der Mittelebene zwischen den Geleisen aneinandergrenzen. Auf diese Weise ist es möglich, die an ein Gleis angrenzenden Teile der Mittelwand zu entfernen, wenn dies z.B. für Arbeiten an den Schienen oder dem Schotterbett nötig ist. Falls an der Außenseite der Geleise die aus der EP PS 85765 be­kannte Schallschutzvorrichtung vorgesehen ist, können die entfernten Teile auf derselben, nachdem sie nach außen versetzt worden ist, vorzugsweise auf den Tragarmen derselben abgelegt werden.In order to enable the central wall according to the invention to be removed on one side, it can be provided that the central wall consists of two preferably mirror-symmetrical parts which adjoin one another in the region of the central plane between the tracks. In this way it is possible to remove the parts of the middle wall adjoining a track, e.g. is necessary for work on the rails or the ballast bed. If the soundproofing device known from EP PS 85765 is provided on the outside of the track, the removed parts can be placed thereon, after it has been moved outwards, preferably on the support arms thereof.

Wenn, wie im Rahmen der Erfindung vorgesehen, die Teile der Mittelwand an den Pfählen einzeln lösbar befestigt sind, dann ist verhindert, daß nach dem Entfernen von Teilen die anderen Teile der Mittelwand umfallen.If, as provided in the context of the invention, the parts of the middle wall are individually detachably fastened to the piles, then it is prevented that after the removal of parts the other parts of the middle wall fall over.

Erfindungsgemäß kann zur Gewichtseinsparung vorgesehen sein, daß die Teile einen C-förmigen Querschnitt auf­weisen.According to the invention can be provided to save weight be that the parts have a C-shaped cross section.

In einer Ausführungsform ist zur Verbesserung der Schallschutzwirkung vorgesehen, daß die als Steg aus­gebildete Mittelwand als Träger (Fundament) für von ihr nach oben zwischen die Lichtraumprofile weisende Wand­elemente vorgesehen ist. Dabei können die nach oben wei­senden Wandelemente bezüglich der Mittelebene asymme­trisch angeordnet sein. .In one embodiment, in order to improve the soundproofing effect, it is provided that the central wall, which is designed as a web, is provided as a support (foundation) for wall elements which point upwards between the light space profiles. The wall elements pointing upwards can be arranged asymmetrically with respect to the central plane. .

Die Erfindung wird an Hand zweier Ausführungsbeispiele der erfindungsgemäßen Lärmschutzeinrichtung näher erläutert, die in den Fig. l und 2 der Zeichnung im Querschnitt dargestellt sind.The invention is explained in more detail with reference to two exemplary embodiments of the noise protection device according to the invention, which are shown in cross section in FIGS. 1 and 2 of the drawing.

Von zwei benachbarten Gleisen ist in Fig. l jeweils die innere Schiene l eingezeichnet, die auf Schwellen 2 auf­liegt bzw. befestigt ist. Die Mittelebene zwischen den beiden Gleisen ist mit 3, die Lichtraumprofile der beiden Gleise sind im mittleren Bereich mit 4 bezeichnet.The inner rail 1 of two adjacent tracks is shown in FIG. 1, which lies on or is fastened to sleepers 2. The middle plane between the two tracks is labeled 3, the clearance profiles of the two tracks are labeled 4 in the central area.

Man sieht eine Mittelwand 5, die in Fig. l in Form eines begehbaren Bahnsteiges ausgebildet ist, und die unter die Randbereiche der beiden benachbarten Lichtraumprofile 4 ragt, so daß zwischen der Mittelwand 5 und den Lichtraum­profilen 4 ein nur schmaler Spalt l2 verbleibt.One can see a middle wall 5, which is designed in FIG. 1 in the form of a walk-on platform, and which projects under the edge regions of the two adjacent clearance profiles 4, so that only a narrow gap l2 remains between the middle wall 5 and the clearance profiles 4.

Zur Sicherung der Mittelwand 5 gegen Querverschieben und zur Lagesicherung sind im Untergrund entlang der Mittel­ebene 3 zwischen den Gleisen Pfähle 6 verankert, die in eine Öffnung, vorzugsweise in eine Längsnut 7 in der Mitte der Unterseite der Mittelwand 5 eingreifen.To secure the middle wall 5 against transverse displacement and to secure the position, piles 6 are anchored in the underground along the middle plane 3 between the rails, which engage in an opening, preferably in a longitudinal groove 7 in the middle of the underside of the middle wall 5.

Die Mittelwand 5 ist in Elemente von z.B. 5 m Länge un­terteilt, die auf dem Schotterbett 8 des Schienenober­baues nivelliert und beispielsweise nach oben abhebbar angeordnet sind.The middle wall 5 is divided into elements of, for example, 5 m in length, which are leveled on the ballast bed 8 of the rail superstructure and are arranged, for example, to be lifted upwards.

Die im dargestellten Fall als begehbarer bahnsteig­ähnlicher Steg ausgebildete Mittelwand 5 hat eine Höhe von 365 mm ab Oberkante der Schienen l und eine Breite von 760 mm und besteht aus Vollmaterial, als welches beispielsweise Beton verwendet wird.The central wall 5, which is designed as a walkable platform-like web in the case shown, has a height of 365 mm from the upper edge of the rails 1 and a width of 760 mm and consists of solid material, for example concrete.

Es ist aber auch möglich, die Mittelwand 5 mit einem kamm- oder E-förmigen Querschnitt auszubilden, der in Fig. l mit unterbrochenen Linien eingezeichnet ist.However, it is also possible to design the central wall 5 with a comb-shaped or E-shaped cross section, which is shown in broken lines in FIG. 1.

In der gleichen Weise ist in der Zeichnung die Mög­lichkeit angedeutet, an die Mittelwand 5 an einer oder beiden Seiten eine Stufe 5ʹ anzubauen.In the same way, the possibility of adding a step 5 'to the central wall 5 on one or both sides is indicated in the drawing.

Bei der in Fig. 2 gezeigten Ausführungsform besteht die Mittelwand 5 aus zwei im Bereich der Mittelebene 3 Rücken an Rücken aneinanderliegenden Teilen 9 und l0 beispiels­weise mit C-profilförmigem Querschnitt. Die Teile 9 und l0 sind mit den Pfählen 6 z.B. über Schranken l3 verbun­den, so daß die Teile der Mittelwand 5 nicht umfallen können, wenn einer der Teile 9 oder l0 entfernt wurde.In the embodiment shown in FIG. 2, the middle wall 5 consists of two parts 9 and 10 lying back to back in the region of the middle plane 3, for example with a C-shaped cross section. The parts 9 and 10 are with the piles 6 e.g. connected by barriers l3 so that the parts of the middle wall 5 cannot fall over if one of the parts 9 or 10 has been removed.

An Stelle der oder zusätzlich zu Stufe 5ʹ können einzelne der Teile 9 oder l0 durch Stufenelemente, die in Längs­richtung der Mittelwand 5 nach oben oder nach unten füh­ren, ersetzt sein. Es können aber auch mit Stufen ausge­stattete Teile in die Mittelwand eingesetzt werden.Instead of or in addition to step 5ʹ, individual parts 9 or 10 can be replaced by step elements which lead upwards or downwards in the longitudinal direction of the central wall 5. Parts with steps can also be inserted into the middle wall.

Die erfindungsgemäß ausgebildete Trennwand 5 kann sowohl bei der Ausführungsform von Fig. l als auch bei der von Fig. 2 als Fundament für weiter nach oben ragende Wand­elemente ll dienen. Diese Wandelemente können wahlweise zur Mittelebene 3 symmetrisch oder asymmetrisch ange­ordnet sein. Auch Ausführungsformen mit quer zur Mit­telebene 3 verstellbaren Wandelementen ll sind möglich.The partition 5 designed according to the invention can serve both in the embodiment of FIG. 1 and in that of FIG. 2 as a foundation for wall elements 11 projecting further upwards. These wall elements can optionally be arranged symmetrically or asymmetrically with respect to the central plane 3. Embodiments with wall elements 11 adjustable transversely to the central plane 3 are also possible.

Die erfindungsgemäße Mittelwand 5 hat zusätzlich zu ihrer guten Lärmschutzwirkung auch den Vorteil, daß sie als Aussteigehilfe ("Bahnsteig") dient, wenn ein Zug einmal auf freier Strecke liegenbleibt und die Fahrgäste oder das Zugbegleitpersonal aussteigen muß.In addition to its good noise protection effect, the central wall 5 according to the invention also has the advantage that it can be used as a Disembarkation aid ("platform") is used if a train has ever been left on the free route and the passengers or the train attendants have to disembark.

Die Teile der erfindungsgemäßen Mittelwand können unmit­telbar am Schotterbett 8 oder auf auf diesem aufgelegten oder in dieses eingebetteten Platten l2 z.B. aus Beton, aufliegen.The parts of the middle wall according to the invention can be located directly on the ballast bed 8 or on plates 12 placed thereon or embedded therein, e.g. made of concrete.
