Description

Verfahren zur Sanierung und Stabilisierung von Eisenbahngleisen Processes for the rehabilitation and stabilization of railway tracks
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Sanierung und Stabilisierung von Eisenbahngleisen mit Schotterunterbau und nicht verschweißtem Schienen¬ strang im Stoßbereich der Schienenstränge. Eisenbahn¬ gleise herkömmlicher Bauart waren nicht verschweißt und wurden hauptsächlich auf hölzernen Eisenbahnschwellen mit Schotterunterbau verlegt. Im Stoßbereich zweier Schienen sind diese Gleise mit Laschen verbunden, wel¬ che Schlitzlöcher aufweisen, so daß die jahreszeitlich bedingten Schwankungen der Schienenlänge im Stoßbereich ausgeglichen werden können. Die Schwelle im Stoßbereich ist dadurch stets besonderen Belastungen ausgesetzt, so daß es insbesondere bei diesen Schwellen zu Schäden an der Schwelle kommt, die eine Sanierung oder gar den vorzeitigen Ersatz dieser Schwelle erforderlich machen.The present invention relates to a method for the rehabilitation and stabilization of railroad tracks with ballast substructure and non-welded rail track in the joint area of the rail tracks. Railway tracks of conventional design were not welded and were mainly laid on wooden railway sleepers with a ballast foundation. In the joint area of two rails, these tracks are connected with tabs which have slotted holes so that the seasonal fluctuations in the rail length in the joint area can be compensated for. As a result, the threshold in the impact area is always exposed to special loads, so that there is damage to the threshold, in particular with these thresholds, which necessitates the renovation or even the premature replacement of this threshold.
Auch bei verschweißten Eisenbahngleisen werden diese aus meßtechnischen Gründen künstlich unterbrochen und elektrisch isoliert. Es handelt sich um die sogenannten Isolierstöße. Auch in diesem Bereich ist es notwendig, den Schotterunterbau häufig neu zu stopfen.Even on welded railway tracks, these are artificially interrupted for electrical engineering reasons and electrically isolated. It is the so-called insulation joints. In this area, too, it is necessary to replant the ballast substructure frequently.
Bei älteren Bahngleisen liegt der Stoßbereich im allge¬ meinen auf einer Holzschwelle, welche die gesamten Be¬ lastungen aufnehmen muß. Man hat daher auch schon Eisen¬ bahngleise verlegt, bei denen der Stoßbereich auf zwei Holzschwellen liegt. Bei den sogenannten Isolierstößen wird der Stoßbereich stets zwischen zwei Schwellen ver¬ legt, um unerwünschte Kriechströme zu vermeiden.In the case of older train tracks, the joint area is generally on a wooden sleeper, which has to absorb the entire load. For this reason, railroad tracks have already been laid where the joint area lies on two wooden sleepers. In the so-called insulating joints, the joint area is always laid between two sleepers in order to avoid undesirable leakage currents.
Die Erfindung hat sich die Aufgabe gestellt, derartige Sanierungen zu vereinfachen und darüber hinaus die Le- bensdauer der Schwelle bzw. der Schwellen sowie des Unterhaus im Stoßbereich zu verlängern, so daß Sanie¬ rung und/oder Ersatz dieser Schwellen erst nach wesent¬ lich längeren Zeiträumen notwendig ist.The object of the invention is to simplify such refurbishments and, moreover, to extend the service life of the threshold or the sleepers as well as the lower house in the joint area, so that renovation and / or replacement of these sleepers is only necessary after considerably longer periods.
Diese Aufgabe kann überraschend einfach dadurch gelöst werden, daß das Schottermaterial im Stoßbereich minde¬ stens bis zu den jeweils benachbarten Schwellen mit einem Mehrkomponentenkleber verklebt wird.This problem can be solved surprisingly simply by gluing the ballast material in the joint area at least up to the respectively adjacent sleepers with a multi-component adhesive.
Durch diese Verklebung wird die Schwelle im Stoßbereich entlastet, da sich die Belastung zumindest auch auf die jeweils benachbarten Schwellen und den dazwischenlie¬ genden, mit Schotter gefüllten Zwischenraum verteilt. Die statische und dynamische Belastung der Schwelle im Stoßbereich verringert sich somit auf einen Bruchteil der herkömmlichen Belastung.This bonding relieves the threshold in the joint area, since the load is at least distributed to the neighboring thresholds and the intermediate space filled with ballast. The static and dynamic load on the threshold in the impact area is thus reduced to a fraction of the conventional load.
Der Mehrkomponentenkleber wird vorzugsweise so aufge¬ tragen, daß die Komponenten des Klebers räumlich von¬ einander getrennt mit einem Druck von 30 bis 200 bar an eine Mischkammer herangeführt, in der Mischkammer tur¬ bulent miteinander gemischt werden und das Gemisch mit einem Druck von 2 bis 6 bar in Form eines flachen, vor¬ hangartigen Filmes laminar auf das Schottermaterial aufgetragen wird. Vorzugsweise wird dabei lösungsmit¬ telfrei gearbeitet.The multicomponent adhesive is preferably applied in such a way that the components of the adhesive are spatially separated from one another at a pressure of 30 to 200 bar and brought to a mixing chamber in the mixing chamber, mixed turbulently with one another and the mixture at a pressure of 2 to 6 bar in the form of a flat, curtain-like film is laminarly applied to the ballast material. Solvent-free work is preferably carried out.
Ein derartiges Verfahren ist beispielsweise beschrieben in der WO 91/08056 der Anmelderin. Das Verfahren ist einfach, wirtschaftlich und umweltfreundlich durchführ¬ bar, da eine Belastung der Umwelt durch Lösungsmittel- dä pfe und/oder Sprühnebel vermeidbar ist.Such a method is described, for example, in WO 91/08056 by the applicant. The process can be carried out in a simple, economical and environmentally friendly manner, since pollution of the environment by solvent vapors and / or spray mist can be avoided.
Der Zweikomponentenkleber wird dabei in der Weise und in solchen Mengen aufgetragen, daß die Teile des Schot- . . .The two-component adhesive is applied in such a way and in such quantities that the parts of the sheet , , ,
ters zwar vollständig benetzt werden und zumindest an den Berührungspunkten klebende Brücken entstehen, es werden jedoch die Hohlräume nicht mit dem Material ge¬ füllt. Dadurch bleiben die Porosität, die Durchlässig¬ keit und die Elastizität des Schotterbettes erhalten. Dennoch wird ein erheblicher Teil der mechanischen Be¬ lastung über das so verklebte Schotterbett auf die je¬ weils benachbarte Schwelle übertragen.Although they are completely wetted and adhesive bridges are formed at least at the points of contact, the cavities are not filled with the material. As a result, the porosity, permeability and elasticity of the ballast bed are retained. Nevertheless, a considerable part of the mechanical load is transferred to the respective neighboring threshold via the ballast bed bonded in this way.
Das Verfahren eignet sich somit insbesondere zur ein¬ fachen und raschen Sanierung älterer Bahnstrecken, die noch aus insbesondere hölzernen Eisenbahnschwellen mit Schotterunterbau und nicht verschweißtem Schienenstrang bestehen. Weiterhin geeignet ist das Verfahren für die aus meßtechnischen Gründen künstlich angelegten Unter¬ brechungen des Gleises, die sogenannten Isolierstöße.The method is therefore particularly suitable for the simple and rapid refurbishment of older railway lines which still consist in particular of wooden railway sleepers with ballast substructure and a non-welded rail track. The method is also suitable for the interruptions of the track artificially created for measurement reasons, the so-called insulating joints.
Vor der Durchführung des erfindungsgemäßen Verfahrens empfiehlt es sich, das Gleis neu zu stopfen und zu justieren. Nach der erfindungsgemäßen Sanierung und Stabilisierung im Stoßbereich der Gleise kann das Gleis insgesamt über längere Zeit ohne weitere Stabilisie- rungs- und Sanierungsmaßnahmen benutzt werden. Before carrying out the method according to the invention, it is advisable to re-stuff and adjust the track. After the renovation and stabilization according to the invention in the joint area of the tracks, the track as a whole can be used for a long time without further stabilization and renovation measures.
