Die Erfindung betrifft ein Dichtungsmaterial mit einer Schutzschicht gegen starke mechanische Belastungen, insbesondere gegen durch Schotter verursachte, bestehend aus einer Dichtungsschicht, die mit einer durch mechanisch sehr widerstandsfähige Bitumenelastomere beschichtete Faserarmierung aufgebaut ist.The invention relates to a sealing material with a protective layer against strong mechanical loads, in particular against caused by crushed stone, consisting of a waterproofing layer with a mechanical very resistant bitumen elastomer coated fiber reinforcement is constructed.
Mit derartigen Dichtungsmaterialien soll die Ausbesserung der Dichtungsschichten auf Brücken und Viadukten unter Eisenbahnschienen oder von Dämmen oder Aushüben im offenen Gelände, deren geologische Struktur eine Abdichtung der Oberfläche erforderlich macht, ermöglicht werden. Dabei soll der Eisenbahnverkehr über eine möglichst geringe Zeitdauer unterbrochen oder verlangsamt werden.Such sealing materials are intended to be used to repair the sealing layers on bridges and viaducts below Railway tracks or of dams or excavations in open terrain, the geological structure of which is a seal of the Surface makes it necessary to be made possible. The railway traffic should take place over the shortest possible period of time interrupted or slowed down.

- eine dritte Bitumenschicht, armiert mit einem Polyester von 350 g/m2 .- a third bitumen layer, reinforced with a polyester of 350 g / m 2 .
2. Im offenen Gelände wird die Dichtungsbahn aus einem Bitumen oder einem mit einem Polyester von 200 bis 350 g/m2 armierten polymeren Bitumen gebildet.2. In the open area, the waterproofing membrane is made of a bitumen or a polymeric bitumen reinforced with a polyester of 200 to 350 g / m 2.
Bei der Anwendung der bekannten Dichtungsmaterialien werden nach Unterbrechung des Verkehrs die Schienen abgebaut, der Schotter abgetragen, die Dichtungsschicht entfernt und an der Stelle ausgebessert. Dann wird der Schotter mit oder ohne Split wiederaufgebracht, darauf die Schienen gelegt und verkeilt.When using the known sealing materials, the rails are dismantled after traffic is interrupted Gravel removed, the sealing layer removed and repaired at the point. Then the gravel with or reapplied without split, the splints placed on top and wedged.
Die Dichtungsschicht ist aus einem Material aufgebaut, das in den oben erwähnten Alternativen beschrieben ist. Die dabei verwendeten Schichten sind 1 m breit, so daß es er- . forderlich ist, das Bitumen bei der Anwendung zu schmelzen. Dabei wird eine zeitaufwendige und sorgfältige Arbeit benötigt. The sealing layer is constructed from a material which is described in the alternatives mentioned above. the The layers used are 1 m wide, so that it it is necessary to melt the bitumen during use. Time-consuming and careful work is required.

Das Wiederaufbringen der Schienen wird dann ersetzt, durch das Absenken mit der Hebevorrichtung.as mentioned above, with the exception of removing the rails. The reattachment of the splints is then replaced, by lowering with the lifting device.
Nach der Durchführung der Abdichtungsarbeiten wird die Dichtungsschicht während des Aufbringens des Schotters und der Schienen sowie später beim Überfahren der Züge einer erheblichen mechanischen Belastung ausgesetzt. Diese führt zu einem Eindrücken der Schottersteine in die Abdichtschicht, wodurch diese durchlöchert werden kann.After the waterproofing work has been carried out, the waterproofing layer is applied during the application of the ballast and the rails as well as later when the trains run over are exposed to considerable mechanical stress. This leads to press the ballast stones into the sealing layer, whereby this can be perforated.
Der Erfindung liegt die Aufgabe zugrunde, ein Dichtungsmaterial der eingangs erwähnten Art zu erstellen, das eine ausreichende Stabilität aufweist und einfach zu verlegen ist.The invention is based on the object of creating a sealing material of the type mentioned, which has a has sufficient stability and is easy to lay.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Dichtungsschicht vorgefertigt mit einer dicken Schutzschicht aus einem Filz aus Mineralfasern oder aus nicht faulenden organischen Fasern beschichtet ist.This object is achieved in that the Sealing layer prefabricated with a thick protective layer made of a felt made of mineral fibers or not decaying organic fiber is coated.
Dabei erstreckt sich die Schutzschicht vorzugsweise wenigstens über die Breite des Schotters, wobei die Dicke der Schutzschicht größer als 5 mm, vorzugsweise 10 mm, ist und wobei das Gewicht zwischen 300 g/m2 und über 800 g/m2 liegt. Der Filz ist vorzugsweise aus Polyester-, Polyamid-, Polyolefin-, Pol.yvinyl-Chlorid-Fasern oder einer Mischung dieser Fasern gebildet.The protective layer preferably extends at least over the width of the ballast, the thickness of the protective layer being greater than 5 mm, preferably 10 mm, and the weight being between 300 g / m 2 and more than 800 g / m 2 . The felt is preferably formed from polyester, polyamide, polyolefin, polyvinyl chloride fibers or a mixture of these fibers.

einfach verlegen und ist zur Durchführung der Reparaturen der Dichtungsschicht in kürzester Zeit geeignet. Hierzu werden die Schienen etwa 30 bis 40 cm mit Hilfe einer Hebevorrichtung angehoben und der Schotter abgetragen. Daraufhin wird die Dichtungsschicht entfernt und das neue Dichtmaterial, vorzugsweise in Barrenform in Richtung der Schienen ausgerollt. Danach wird der Schotter wieder aufgetragen und die Schienen befestigt. Daraufhin kann der Verkehr sofort mit normaler Geschwindigkeit wieder fließen, so daß eine enorme Zeitersparnis erzielt wird. Das Material ist vorzugsweise breiter als die Schienen und steht über diese auf jeder Seite hervor. Dann werden die Dichtungsschichten auf beiden Seiten der Schienen mit den fortgesetzten Dichtungsschichten zusammengepaßt, so daß die gewünschte dichte Schicht entsteht.easy to lay and is used to carry out repairs suitable for the sealing layer in a very short time. For this purpose, the rails are about 30 to 40 cm with the help of a lifting device raised and the gravel removed. The sealing layer is then removed and the new sealing material, preferably rolled out in the form of bars in the direction of the rails. Then the ballast is applied again and fastened the rails. Thereupon the traffic can immediately flow again at normal speed, so that a enormous time savings are achieved. The material is preferably wider than the rails and overhangs them on each side. Then the sealing layers on both sides of the rails with the sealing layers continued matched to form the desired dense layer.
Die Erfindung bietet folgende überraschende Vorteile:The invention offers the following surprising advantages:
— Das Dichtmaterial braucht lediglich unter den Schienen ausgerollt zu werden, wobei die Dichtungsbahnen so lang sein können, wie es die Vorfertigung in der Fabrik erlaubt, so daß, abgesehen von den Stoßstellen am Bahnende, weder Verklebungen noch Verschweißungen vorgesehen werden müssen.- The sealing material only needs to be rolled out under the rails, the sealing sheets as long can be, as the prefabrication in the factory allows, so that, apart from the joints at the end of the web, neither gluing nor welding are provided have to.
- Wegen der erstellbaren Größe kann das erfindungsgemäße Dichtmaterial über die Schwellen der Schienen seitlich herausragen, so daß eine Verlegung mit einer durchgehenden Dichtungsschicht über die Schienen hinaus möglich ist.- Because of the size that can be created, the inventive Sealing material protrude laterally over the thresholds of the rails, so that a laying with a continuous Sealing layer beyond the rails is possible.
