Abstract

PCT No. PCT/EP93/01088 Sec. 371 Date Mar. 6, 1995 Sec. 102(e) Date Mar. 6, 1995 PCT Filed May 5, 1993 PCT Pub. No. WO93/22502 PCT Pub. Date Nov. 11, 1993The process for the temporary consolidation of railroad track ballast, in particular during the time of redevelopment or reconstruction of a parallel set of tracks, is performed in that the ballast is cemented partially in particular in the side area by a multi component adhesive, wherein this cementation may be broken up mechanically later without affecting reuse of the ballast.

Description

Gegenstand der vorliegenden Erfindung ist ein Verfahren zur temporären Verfestigung eines Schotterbettes für Eisenbahngleise für die Zeit der Sanierung oder des Neubaus eines parallelen Gleisstranges. Eine derartige temporäre Verfestigung des Schotterbettes für Eisenbahngleise erfolgte bisher durch Einrammen von S-förmigen Eisenbohlen neben dem Bahngleis oder das Einschlagen von Eisenkästen mit seitlichen angespitzten Verankerungen. Ohne derartige temporäre Verfestigungen würde das Schotterbett durch die Erschütterungen des Bahnverkehrs einerseits sowie durch die Vibrationen und Erschütterungen neben dem Schotterbett bei der Sanierung oder dem Neubau eines parallelen Gleisstranges andererseits davonschwimmen und dadurch die Stabilität und Justierung des Eisenbahngleises gefährden.The present invention relates to a method for Temporary consolidation of a ballast bed for railroad tracks for the time of renovation or new construction of a parallel track. Such a temporary consolidation The ballast bed for railroad tracks has so far been used by ramming S-shaped iron planks next to the train track or hammering iron boxes with sharpened ones on the side Anchorages. Without such temporary solidifications the ballast bed by the shocks of rail traffic on the one hand and by the vibrations and shocks alongside the ballast bed when renovating or building a parallel one On the other hand, the line of tracks floats away and thereby the Endanger the stability and adjustment of the railway track.

Das Einrammen der S-förmigen Eisenstäbe, aber auch das Einschlagen der Befestigungskästen mit Verankerungen ist mit einer erheblichen Lärmbelästigung verbunden, die insbesondere in der Nähe von Wohngebieten kaum zu ertragen ist. Die Erfindung hat sich somit die Aufgabe gestellt, ein Verfahren zur temporären Verfestigung eines Schotterbettes für Eisenbahngleise zur Verfügung zu stellen, welches einfach, sicher und geräuscharm durchgeführt werden kann.The ramming of the S-shaped iron bars, but also the driving in the fastening boxes with anchors are with a considerable noise pollution, particularly in the Near residential areas is hardly bearable. The invention has set itself the task of a procedure for temporary Solidification of a ballast bed for railway tracks for To provide which is simple, safe and quiet can be carried out.

Diese Aufgabe kann überraschend einfach dadurch gelöst werden, daß ein Mehrkomponentenkleber in solcher Menge auf das Schotterbett aufgetragen wird, daß eine Verankerung bis zum Untergrund erfolgt und dennoch die Hohlräume nicht gefüllt werden, so daß diese Verklebung später mechanisch wieder aufgebrochen werden kann, ohne die Wiederverwendung des Schottermaterials zu beeinträchtigen, wobei die Komponenten des Klebers räumlich voneinander getrennt mit einem Druck von 30 bis 200 bar an eine Mischkammer herangeführt, in der Mischkammer turbulent miteinander gemischt werden und das Gemisch mit einem Druck von 2 bis 6 bar in Form eines flachen vorhangartigen Filmes laminar auf das Schotterbett aufgetragen wird.This task can be solved surprisingly simply by that a multicomponent adhesive in such an amount on the ballast bed is applied that anchoring to the ground takes place and yet the cavities are not filled, so that this bond can later be broken mechanically again can, without affecting the reuse of the ballast material, taking the components of the adhesive spatially apart separately at a pressure of 30 to 200 bar to a mixing chamber introduced, turbulent with each other in the mixing chamber are mixed and the mixture at a pressure of 2 to 6 bar in the form of a flat curtain-like film laminar on the Ballast bed is applied.

Die Möglichkeit der Wiederverwendung ist vor allem deshalb wichtig, weil häufig nach dem Neubau oder der Sanierung des einen Gleisstranges anschließend der Zugverkehr hierüber geleitet wird und dann das zuvor benutzte Gleis saniert oder erneuert werden soll. Dabei soll das Schottermaterial stets wiederverwendet werden. Die Verklebung darf daher nicht so intensiv erfolgen, daß sie nicht wieder aufgebrochen werden kann.The possibility of reuse is mainly because of this important because often after the new building or the renovation of the one train line later the train traffic passed over it and then the previously used track is renovated or renewed shall be. The ballast material should always be reused will. The bonding should therefore not be so intense that they cannot be broken open again.

Der Mehrkomponentenkleber wird dadurch aufgetragen, daß die Komponenten des Klebers räumlich voneinander getrennt mit einem Druck von 30 bis 200 bar an eine Mischkammer herangeführt, in der Mischkammer turbulent miteinander gemischt werden und das Gemisch mit einem Druck von 2 bis 6 bar in Form eines flachen vorhangartigen Filmes laminar auf das Schotterbett aufgetragen wird. Dieses Verfahren verhindert ein vorzeitiges Aufreißen des Filmes und die Bildung von Sprühnebeln. Weiterhin gestattet dieses Verfahren, lösungsmittelfrei zu arbeiten. Dieses Verfahren gewährleistet darüber hinaus, daß das Schottermaterial zunächst vollflächig benetzt wird und an den Berührungspunkten klebende Brücken entstehen. Keinesfalls sollen jedoch die Hohlräume gefüllt werden, da dies das Wiederaufbrechen und die Wiederverwendung des Schottermaterials unmöglich machen würde.The multi-component adhesive is applied in that the Components of the adhesive spatially separated from one another with a Pressure from 30 to 200 bar to a mixing chamber, in the mixing chamber are mixed turbulently and that Mixture with a pressure of 2 to 6 bar in the form of a flat laminar curtain-like film applied to the ballast bed becomes. This procedure prevents the opening of the Film and the formation of spray. Still allowed this process of working solvent-free. This method also ensures that the ballast material is initially wetted over the entire surface and at the points of contact adhesive bridges are created. Under no circumstances should they Cavities are filled as this is the breakup and the Would make it impossible to reuse the ballast material.

Das Verfahren zum Auftragen geeigneter Mehrkomponentenkleber sowie eine hierfür geeignete Vorrichtung sind beispielsweise beschrieben in der WO 91/08056 der Anmelderin. Diese Druckschrift enthält keine Hinweise, daß es möglich ist, mit Hilfe dieses Verfahrens die bisher üblichen Maßnahmen wie Einrammen von S-förmigen Eisenbohlen oder Einschlagen von Eisenkisten mit seitlich angespitzten Verankerungen zu ersetzen. Bei Verwendung von zuviel Mehrkomponentenkleber füllen sich die Hohlräume hiermit. Eine derartige Verfüllung der Hohlräume ist auf alle Fälle zu vermeiden, da das Schotterbett dadurch primär seine Drainagefähigkeit verliert und zum anderen es unmöglich ist, das Gleisbett in der Weise wiederaufzubrechen, daß die Schottersteine erneut verwendet werden können.The process for applying suitable multi-component adhesives and a device suitable for this are, for example described in WO 91/08056 by the applicant. This publication contains no evidence that it is possible using this procedure the usual measures such as ramming of S-shaped iron planks or driving in iron boxes to replace laterally pointed anchors. Using too much multi-component glue fills the cavities herewith. Such filling of the cavities is on everyone Avoid cases, as this is primarily the ballast bed Drainage ability loses and secondly it is impossible to break up the track bed in such a way that the ballast stones can be used again.

Bei der erfindungsgemäßen Verwendung des Verfahrens gemäß WO 91/08056 ist es somit nötig, zwischen einer nicht ausreichenden Verfestigung und einer zu starken Verfestigung zu arbeiten.When using the method according to WO according to the invention 91/08056 it is therefore necessary to choose between an insufficient Consolidation and too strong consolidation to work.

Powell und Shenton befassen sich in der Zeitschrift "Railway Engineer International, Band 5, Nr. 1, Januar 1980, Seiten 51 bis 54 mit der Frage, ob es überhaupt sinnvoll und gut ist, das Schottermaterial durch Verklebung zu stabilisieren. Sie kommen letztendlich zu der Schlußfolgerung, daß dies noch sehr fraglich ist, da alle bis dahin durchgeführten Versuche zu keinen brauchbaren Ergebnissen geführt haben; vgl. insbesondere die Zusammenfassung auf Seite 54 dieses Artikels.Powell and Shenton look at the "Railway Engineer International, Volume 5, No. 1, January 1980, pages 51 to 54 with the question of whether it makes sense and is good at all Stabilize ballast material by gluing. they are coming ultimately to the conclusion that this is still very questionable is because all the experiments carried out up to now have been of no use Have had results; see. especially the summary on page 54 of this article.

Zur Durchführung des erfindungsgemäßen Verfahrens wird zumindest im Seitenbereich des Schotterbettes so viel Mehrkomponentenkleber aufgetragen, daß eine Verankerung bis zum Untergrund erfolgt. Beim späteren Wiederaufreißen des Schotterbettes zwecks Sanierung oder Neubau auch dieses Gleisstranges hat sich gezeigt, daß die punktuellen Verklebungen des Schottermaterials wieder aufgerissen werden können, ohne das Schottermaterial zu zerstören. Dieses Schottermaterial kann somit ohne weiteres wiederverwendet werden.To carry out the method according to the invention, at least so much multi-component adhesive in the side area of the ballast bed plotted that anchoring to the underground. When opening again later the ballast bed for the purpose of renovation or new construction this line of tracks has also shown that the punctual gluing of the ballast material again can be torn open without the gravel material to destroy. This crushed stone material can therefore be used easily be reused.

Die Auftragung des Zweikomponentenklebers erfolgt praktisch ohne Lärmbelästigung der Nachbarschaft und obendrein umweltfreundlich, da auf die Verwendung organischer Lösungsmittel verzichtet und die Ausbildung von Sprühnebeln vermieden wird. Die Haltbarkeit der Verklebung des Schottermaterials ist jedoch völlig ausreichend, den Gleiskörper für mehrere Monate auch bei starken Erschütterungen und Belastungen zu stabilisieren, ohne ihn seitlich gegen "Wegschwimmen" mechanisch abzusichern.The two-component adhesive is applied practically without noise pollution from the neighborhood and on top of that environmentally friendly because of the use of organic Solvents waived and the formation of Spray mist is avoided. The durability of the bond of the gravel material is however completely sufficient, the track body for several months, even with strong ones Stabilize vibrations and loads, without mechanically securing it laterally against "swimming away".

Das erfindungsgemäße Verfahren ist auch gut geeignet, Gleiskörper mit einem Schotterbett zu stabilisieren, wenn in der Nähe Rammarbeiten oder sonstige Arbeiten durchgeführt werden müssen, die zu langanhaltenden und intensiven Erschütterungen des Schotterbettes führen, beispielsweise Sanierungsarbeiten an Brücken, die ebenfalls zu einem "Wegschwimmen" des Schotterbettes führen können.The method according to the invention is also well suited Stabilize the track body with a ballast bed, if pile driving or other work is nearby must be carried out that are too long lasting and cause intense vibrations of the ballast bed, for example, renovation work on bridges, which also lead to a "swimming away" of the ballast bed can.
