Abstract

In the process for the long-term stabilisation of the packing regions of railway track on a ballast bed, especially in the region beneath the sleepers, the grid consisting of the rail and the sleepers firmly secured to it is raised by 1 to 3 cm and the ballast bed beneath the sleeper is sprayed from the sleeper head side with an adhesive, whereafter packing and levelling is done in the usual manner.

Description

Verfahren und Vorrichtung zur längerfristigen Stabilisierung der Stopfbereiche von Bahnσleisen Method and device for the long-term stabilization of the tamping areas of railway tracks
Gegenstand der vorliegenden Erfindung ist ein Verfahren und eine Vorrichtung zur längerfristigen Stabilisierung der Stopfbereiche von Bahngleisen auf einem Schotterbett, insbe¬ sondere im Bereich unter den Schwellen.The present invention relates to a method and a device for the long-term stabilization of the tamping areas of railway tracks on a ballast bed, in particular in the area under the sleepers.
In der FR-A-2 553 445 ist ein Verfahren beschrieben, bei dem der aus Schienen und Schwellen bestehende Gleisrost angehoben und das unter den Schwellen liegende Schotterbett mit einem schäumenden Kleber besprüht wird, woraufhin das Gleisrost wieder abgesenkt wird. Dieses Verfahren hat sich nicht be¬ währt, da diese Schäume bei Belastung rasch zerstört werden und darüber hinaus das Gleisbett wasserundurchlässig wird, so daß binnen kurzem die Schwellen und gegebenenfalls sogar die Schienen durch Regen unter Wasser gesetzt werden.FR-A-2 553 445 describes a method in which the track grate consisting of rails and sleepers is raised and the ballast bed lying under the sleepers is sprayed with a foaming adhesive, whereupon the track grate is lowered again. This method has not proven itself, since these foams are rapidly destroyed under load and, moreover, the track bed becomes impermeable to water, so that within a short time the sleepers and possibly even the rails are put under water by rain.
Aus der EP-A-91 900 018 sind ein Verfahren und eine Vorrich¬ tung zum Auftragen von Mehrkomponentenharzen bekannt, mit welchen ein Mehrkomponentenkleber auf das Schotterbett von Bahngleisen versprüht wird. Dieses Verfahren und diese Vor¬ richtung haben sich ausgezeichnet bewährt und werden inzwi¬ schen in erheblichem Umfang in der Praxis eingesetzt. Bei die¬ sem Einsatz hat sich gezeigt, daß es erstrebenswert wäre, auch die Stopfbereiche von Bahngleisen auf einem Schotterbett - insbesondere im Bereich unter den Schwellen - längerfristig zu stabilisieren. Dieser Bereich des Schotterbettes ist jedoch durch die Schwelle abgedeckt, so daß er nicht mit Hilfe des bekannten Verfahrens und der bekannten Vorrichtung besprüht werden kann.From EP-A-91 900 018 a method and a device for applying multicomponent resins are known, with which a multicomponent adhesive is sprayed onto the ballast bed of railroad tracks. This method and this device have proven to be excellent and are now used to a considerable extent in practice. In this application, it has been shown that it would be desirable to stabilize the tamping areas of railroad tracks on a ballast bed in the long term, particularly in the area under the sleepers. However, this area of the ballast bed is covered by the threshold so that it cannot be sprayed using the known method and the known device.
ERSÄTZBLÄTΓ(REGEL26) Versuche des Herstellers von Stopfmaschinen gemäß DE-B- 23 27 063, die Stopfschaufeln als Zuleitung eines Klebers zu verwenden und während des Stopfens das gestopfte Material hiermit zu besprühen, sind gescheitert, da der Kleber nur die Schottersteine besprühen konnte, welche in unmittelbare Nähe der Sprühöffnung gelangt sind. Es ist jedenfalls nicht gelun¬ gen, den gesamten Schotter im Stopfbereich damit wirksam zu stabilisieren.ERSÄTZBLÄTΓ (REGEL26) Attempts by the manufacturer of tamping machines according to DE-B-23 27 063 to use the tamping blades as a feed line for an adhesive and to spray the stuffed material with them during tamping failed because the adhesive could only spray the ballast stones which were in the immediate vicinity of the Spray opening are reached. In any case, it has not been possible to effectively stabilize the entire ballast in the tamping area.
Die Erfindung hat sich die Aufgabe gestellt, auch die Stopfbe- reiche von Bahngleisen auf einem Schotterbett, insbesondere im Bereich unter den Schwellen, langfristig zu stabilisieren, wobei ebenfalls ein rasches, effektives und umweltfreundliches Vorgehen gefordert wird.The object of the invention is to stabilize the tamping areas of railway tracks on a ballast bed, in particular in the area under the sleepers, in the long term, which also calls for a quick, effective and environmentally friendly procedure.
Diese Aufgabe konnte jetzt überraschend einfach dadurch gelöst werden, daß der Gleisrost, bestehend aus der Schiene und den damit fest verbundenen Schwellen, 1 bis 3 cm angehoben und das unter der Schwelle liegende Schotterbett von der Seite des Schwellenkopfes her mit einem Kleber besprüht wird, woraufhin in üblicher Weise gestopft und egalisiert wird.This task could now be solved surprisingly simply by lifting the track grate, consisting of the rail and the sleepers firmly connected to it, 1 to 3 cm and spraying the ballast bed below the sleeper from the side of the sleeper head with an adhesive, whereupon stuffed and equalized in the usual way.
Vorzugsweise werden Zweikomponentenkleber eingesetzt, wobei die Komponenten des Klebers räumlich voneinander getrennt mit einem Druck von 30 bis 200 bar an eine Mischkammer herange¬ führt, in der Mischkammer turbulent miteinander vermischt und dann als Gemisch mit einem Druck von 2 bis 6 bar in Form eines flachen, vorhangartigeή Filmes laminar in den Hohlraum zwi¬ schen Schwelle und Schotterbett eingebracht werden. Der ver¬ wendete Zweikomponentenkleber ist vorzugsweise wiederum lö¬ sungsmittelfrei.Two-component adhesives are preferably used, the components of the adhesive being spatially separated from one another at a pressure of 30 to 200 bar, being mixed turbulently in the mixing chamber and then being a mixture with a pressure of 2 to 6 bar in the form of a flat one , curtain-like film are introduced laminar in the cavity between the threshold and ballast bed. The two-component adhesive used is preferably again solvent-free.
Das erfindungsgemäße Verfahren kann prinzipiell in der Weise durchgeführt werden, daß der Gleisrost, bestehend aus der Schiene und den damit fest verbundenen Schwellen, jeweils Schwelle für Schwelle 1 bis 3 cm angehoben wird, woraufhin dann von der Seite des Schwellenkopfes her der Zweikomponen¬ tenkleber in den entstehenden Schlitz gesprüht wird. Dieses Verfahren eignet sich insbesondere für kurze Stücke oder Über¬ gangsstücke zwischen einer weichen und einer festen Schienen¬ fahrbahn.The method according to the invention can in principle be carried out in such a way that the track grate, consisting of the rail and the sleepers firmly connected thereto, in each case Threshold for threshold is raised 1 to 3 cm, whereupon the two-component adhesive is then sprayed into the resulting slot from the side of the threshold head. This method is particularly suitable for short pieces or transition pieces between a soft and a solid rail track.
Bei längeren Gleisstrecken empfiehlt es sich hingegen, das Be¬ sprühen in dem Zeitpunkt durchzuführen, in dem der Gleisrost von der Gleisstopfmaschine angehoben ist. Nach dem Einsprühen wird dann in üblicher Weise gestopft und egalisiert. Nach dem Egalisieren kann dann auch das übrige Schotterbett in bekann¬ ter und üblicher Weise besprüht werden, so daß letztendlich das gesamte Schotterbett, insbesondere in dem Bereich neben den Schienen und unter den Schwellen, im Stopfbereich stabili¬ siert wird.With longer track sections, on the other hand, it is advisable to carry out the spraying at the point in time at which the track grate is raised by the tamping machine. After spraying, stuffing and leveling are carried out in the usual way. After leveling, the remaining ballast bed can then also be sprayed in a known and customary manner, so that ultimately the entire ballast bed, in particular in the area next to the rails and under the sleepers, is stabilized in the tamping area.
Zur Durchführung des Verfahrens mit Zweikomponentenklebern eignet sich prinzipiell die gleiche Vorrichtung, wie sie in der EP-A-91 900 018 beschrieben ist, jedoch sollte die Flach¬ strahldüse einen Sprühwinkel unter 90°, vorzugsweise sogar unter 45° aufweisen. Durch diesen engeren Sprühwinkel wird gewährleistet, daß die Hauptmenge des Zweikomponentenklebers wirklich in den Stopfbereich unter der Schwelle gelangt und nicht unnötig viel des Zweikomponentenklebers in den angren¬ zenden Bereich gelangt, der sowieso anschließend in bekannter Weise besprüht werden soll.In principle, the same device as described in EP-A-91 900 018 is suitable for carrying out the process with two-component adhesives, but the flat jet nozzle should have a spray angle of less than 90 °, preferably even less than 45 °. This narrower spray angle ensures that the main amount of the two-component adhesive really gets into the stuffing area below the threshold and not unnecessarily much of the two-component adhesive gets into the adjacent area, which should then be sprayed anyway in a known manner.
Schließlich hat sich gezeigt, daß es erfindungsgemäß vorteil¬ haft ist, die Flachstrahldüse mit einem Vibrator zu verbinden, der die Düse vor allem auf- und abbewegt, gegebenenfalls aber auch seitlich hin und her. Durch diese Vibrationen kommt es zu einer besseren und gleichmäßigeren Verteilung des Klebers in dem Bereich unter der Schwelle. Das erfindungsgemäße Verfahren ist insbesondere geeignet, längere Gleisstrecken zu sanieren und zu stabilisieren, wobei zum Besprühen der Bereiche unter den Schwellen, insbesondere im Stopfbereich, der Zeitpunkt ausgenutzt wird, in welchem die Stopfmaschine die jeweilige Schwelle sowieso um 1 bis 3 cm, vorzugsweise 2 cm anhebt. Außer Eisenbahngleisen können aber auch andere Bahngleise erfindungsgemäß stabilisiert werden, beispielsweise die Gleise von Transportkrähnen, die auf Glei¬ sen hin und her bewegt werden.Finally, it has been found that it is advantageous according to the invention to connect the flat jet nozzle to a vibrator which mainly moves the nozzle up and down, but also back and forth, if necessary. These vibrations result in a better and more even distribution of the adhesive in the area below the threshold. The method according to the invention is particularly suitable for rehabilitating and stabilizing longer track sections, the time being used for spraying the areas under the sleepers, in particular in the tamping area, in which the tamping machine increases the respective threshold by 1 to 3 cm, preferably 2 cm lifts. In addition to railroad tracks, other railroad tracks can also be stabilized according to the invention, for example the rails of transport cranes that are moved back and forth on rails.
Prinzipiell sind erfindungsgemäß sowohl Einkomponentenkleber als auch Kleberdispersionen und Mehrkomponentenkleber geei¬ gnet.In principle, both one-component adhesives and adhesive dispersions and multicomponent adhesives are suitable in accordance with the invention.
Als Zweikomponentenkleber kommen prinzipiell die gleichen Materialien zur Anwendung, die in der EP-A-91 900 018 be¬ schrieben sind. In principle, the same materials that are described in EP-A-91 900 018 are used as two-component adhesives.
