Abstract

The method involves detaching and removing a ground layer (6) mechanically below and/or adjacent to a track (1). The ground layer is initially separated from a substrate before mechanically detaching and removing of the ground layer by cutting (5) a base (3) parallel to the rail. The cutting is provided in even-shape, tub-shape, U-shape or in suitable profile form. The track is supported on sleepers (2) on the base. The base is cut by a cutting belt with a saw tooth or with a cutter head and by pressurizing the base with an air jet or water jet. An independent claim is also included for a device for mechanically removing of a ground layer in a railway track.

Description

Die Erfindung betrifft ein Verfahren zum maschinellen Ausbau von Bodenschichten im Gleisbau nach dem Oberbegriff des Anspruchs 1; die Erfindung betrifft ferner eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the mechanical removal of soil layers in track construction according to the preamble of claim 1; The invention further relates to a device for carrying out the method.

Im Gleisbau gibt es Spezialmaschinen, welche verschiedene Bodenarten wie Schotter, Kies, diverse Böden etc. im maschinellen Verfahren unter dem Gleis lösen und ausbauen. Dieser maschinelle Ausbau wird bislang mittels Mobilbagger oder aber vorzugsweise mit (Spezial-) Fräsmaschinen ausgeführt.In track construction, there are special machines that dissolve and expand various types of soil such as gravel, gravel, various soils etc. in a mechanical process under the track. This mechanical expansion is currently carried out by means of wheeled excavators or preferably with (special) milling machines.

Da - wie ausgeführt - im überwiegenden Teil des maschinellen Ausbaus von Bodenschichten im Gleisbau das Fräsverfahren angewendet wird, bestehen hierbei mehrere Nachteile. So wird beim Fräsverfahren der Boden sehr grob aufgerissen. Dies bedeutet, daß die Aushubsohle grobe Toleranzen und lose Strukturen aufweisen kann. Darüber hinaus ist beim Fräsverfahren die Arbeitsgeschwindigkeit sehr langsam.Since - as stated - the milling process is used in the majority of the mechanical removal of soil layers in track construction, there are several disadvantages here. So the ground is torn open very roughly in the milling process. This means that the excavation bottom can have rough tolerances and loose structures. In addition, in the milling process, the working speed is very slow.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Verfahren zum maschinellen Ausbau von Bodenschichten im Gleisbau zu schaffen; weiterhin soll eine technisch einfache Vorrichtung zur Durchführung des Verfahrens geschaffen werden.Based on this, the object of the invention is to provide an improved method for the mechanical removal of soil layers in track construction; Furthermore, a technically simple device for carrying out the method is to be created.

Die technische Lösung ist verfahrensmäßig gekennzeichnet durch die Merkmale im Kennzeichen des Anspruchs 1.The technical solution is procedurally characterized by the characterizing features of claim 1.

Dadurch ist ein verbessertes Verfahren zum maschinellen Ausbau von Bodenschichten im Gleisbau geschaffen, bei dem die Aushubsohle nur geringe Toleranzen aufweist und wobei die Struktur weiterhin sehr fest ist. Schließlich ist die Arbeitsgeschwindigkeit im Vergleich zu den bekannten Verfahren hoch. Der Grundgedanke des erfindungsgemäßen Verfahrens beruht darauf, mittels einer entsprechenden Schnitteinrichtung eine Trennung der Bodenschichten zu erreichen, um dann die abgetrennten Schichten zu lösen, zu befördern und zu verladen. Damit wird bei dem erfindungsgemäßen Verfahren lediglich eine Trennlinie hergestellt, um die Bodenschichten zu lösen. Der eigentliche Lösevorgang mit Abtransport des Materials erfolgt dann unmittelbar im Nachgang zu der Schnittherstellung. Der Aushub kann dabei gleisgebunden in verschiedenen Bereichen stattfinden. Dies kann beispielsweise unterhalb oder neben dem Gleis geschehen. Somit kann bei diesem Verfahren in der Kombination mit gleisgebundener Maschinentechnik eine neuartige Ausbauart von Bodenschichten zu einer verbesserten Aushubsohle mit einer gesteigerten Ausbaugeschwindigkeit führen. Gerade beim gleisgebundenen Ausbau kann somit eine Leistungssteigerung für vorhandene Umbaumaschinen sowie Umbauverfahren erreicht werden, um so zu einer verbesserten Qualität und gesteigerter Leistung zu kommen.As a result, an improved method of machine construction of soil layers in track construction is provided in which the excavation sole has only small tolerances and the structure is still very strong. Finally, the operating speed is high compared to the known methods. The basic idea of the method according to the invention is based on achieving a separation of the soil layers by means of a corresponding cutting device, in order then to release, convey and load the separated layers. Thus, in the method according to the invention only a dividing line is produced in order to release the soil layers. The actual dissolution process with removal of the material then takes place immediately after the cut production. Excavation can take place in different sections of track. This can happen, for example, below or next to the track. Thus, in this method, in combination with track-bound machine technology, a novel type of soil layer construction can result in an improved excavation floor with an increased rate of expansion. Especially when track-bound expansion can thus be achieved an increase in performance for existing conversion machines and conversion procedures, so as to come to improved quality and increased performance.

Gemäß der Weiterbildung in Anspruch 2 wird der Schnitt im wesentlichen gerade oder wannenförmig oder U-förmig oder in einer anderen geeigneten Profilform durchgeführt. Dies bedeutet, daß nach Durchführung des Schnitts ein Aushub der Bodenschicht in Form des entsprechenden Profils erfolgt.According to the embodiment in claim 2, the section is carried out substantially straight or trough-shaped or U-shaped or in another suitable profile shape. This means that after performing the cut an excavation of the soil layer takes place in the form of the corresponding profile.

Die Weiterbildung gemäß Anspruch 3 schlägt bevorzugte Verfahren für den Schnittvorgang vor. Dabei kann die Sägetechnik mit der Frästechnik kombiniert werden, wobei die Frästechnik den Sägeschnitt unterstützen soll. Die Sägeeinrichtung sowie Fräseinrichtung kann dabei an entsprechenden Schnittbändern angeordnet sein. Um den zuvor erwähnten U-förmigen Schnitt zu realisieren, kann das Schnittband entsprechend U-förmig geführt sein. Entsprechendes gilt auch für den wannenförmigen Schnitt, bei welchem das Schnittband gebogen geführt ist. Es ist aber auch denkbar, daß entsprechend der drei Schenkel des "U" entsprechende separate Schnittbänder vorgesehen sind, welche diese Schenkel definieren. Neben den Sägebändern sowie Fräsbändern können aber auch Wasserdrucktrennanlagen sowie Luftdrucktrennanlagen eingesetzt werden.The development according to claim 3 proposes preferred method for the cutting process. The sawing technology can be combined with the milling technique, whereby the milling technique should support the saw cut. The sawing device and milling device can be arranged on corresponding cutting strips. In order to realize the aforementioned U-shaped section, the cutting band may be guided in a U-shaped manner. The same applies to the trough-shaped section in which the cutting tape is guided bent. However, it is also conceivable that according to the three legs of the "U" corresponding separate cutting bands are provided which define these legs. In addition to the saw bands and milling belts but also water pressure separation systems and air pressure separation plants can be used.

Eine bevorzugte Weiterbildung schlägt gemäß Anspruch 4 vor, daß zum Schneiden oder Fräsen des Bodens ein endlos umlaufendes Sägeband oder Fräsband verwendet wird. Der Vorteil besteht darin, daß durch dieses endlos umlaufende Sägeband/Fräsband eine hohe Sägeleistung erzielt werden kann. Es ist lediglich erforderlich, das Sägeband/Fräsband entsprechend mit Führungen zu versehen und mit einem entsprechenden Antrieb auszustatten.A preferred development proposes according to claim 4, that for cutting or milling of the soil an endlessly circulating saw band or milling belt is used. The advantage is that a high sawing performance can be achieved by this endlessly circulating saw band / milling belt. It is only necessary to provide the saw band / milling belt accordingly with guides and equipped with a corresponding drive.

Während des Umlaufes des Sägebandes/Fräsbandes ist es dann nur noch notwendig, dieses in Gleisrichtung vorwärtszubewegen, so daß sich das endlos umlaufende Sägeband/Fräsband durch den Boden hindurchschneidet.During the circulation of the saw band / milling belt, it is then only necessary to move it forward in the track direction, so that the endlessly circulating saw band / milling belt cuts through the ground.

Die Weiterbildung gemäß Anspruch 5 schlägt zwei Varianten für den Verlauf und damit für die Führung des endlos umlaufenden Sägebandes/Fräsbandes vor. In einer ersten Variante wird die Führung des Sägebandes/Fräsbandes in der Art eines U-Profils vorgeschlagen. Dies bedeutet, daß die Basis sowie die beiden Schenkel des "U" jeweils durch ein mit geringem Abstand einander gegenüberliegendes Sägeband/Fräsband-Paar gebildet sind, wobei jedoch die beiden Sägeband/Fräsband-Abschnitte in entgegengesetzte Richtungen laufen. Dadurch wird die Leistung weiter erhöht. Alternativ ist es in einer zweiten Variante auch denkbar, daß das endlos umlaufende Sägeband/Fräsband als eine Art Ring geführt ist. Dieser "Ring" ist im weitesten Sinne zu verstehen. In erster Linie handelt es sich bei dieser ringförmigen Führung um ein Rechteck, welches im Innern die Mittenöffnung definiert. Selbstverständlich sind auch andere Profilumläufe wie Trapeze, Dreiecke, Polygone etc. denkbar.The development according to claim 5 proposes two variants for the course and thus for the leadership of endlessly circulating saw band / milling belt. In a first variant, the leadership of the saw band / milling belt is proposed in the manner of a U-profile. This means that the base as well as the two legs of the "U" are each formed by a narrowly spaced saw band / Fräsband pair, but with the two saw band / Fräsband sections run in opposite directions. This will further increase performance. Alternatively, it is also conceivable in a second variant that the endlessly circulating saw band / milling belt is guided as a kind of ring. This "ring" is to be understood in the broadest sense. In the first place, this annular guide is a rectangle which defines the center opening in the interior. Of course, other profile circulations such as trapezes, triangles, polygons, etc. are conceivable.

Die technische Lösung schlägt vorrichtungsmäßig vor, daß die Schneidvorrichtung auf dem Gleis verfahrbar ist. Dies bedeutet, daß durch diese gleisgebundene Vorrichtung diese mit anderen Vorrichtungen zum Lösen sowie zum Transport der Bodenschichten in einer Art Kolonne auf dem Gleis kombiniert werden kann.The technical solution proposes the device that the cutting device is movable on the track. This means that this track-bound device can be combined with other devices for dissolving and transporting the soil layers in a type column on the track.

In den Fig. 1 bis 4 ist eine erste Ausführungsform und in den Fig. 5 bis 7 eine zweite Ausführungsform zum maschinellen Ausbau von Bodenschichten im Gleisbau dargestellt.In the Fig. 1 to 4 is a first embodiment and in the Fig. 5 to 7 a second embodiment for the mechanical removal of soil layers in track construction shown.

Bei der ersten Ausführungsform in den Fig. 1 bis 4 ist dargestellt, wie ein Gleis 1 auf seinen Schwellen 2 auf dem Boden 3 gelagert ist. Auf dem Gleis 1 sind Bearbeitungsfahrzeuge 4 verfahrbar angeordnet.In the first embodiment in the Fig. 1 to 4 It is shown how a track 1 is mounted on its sleepers 2 on the floor 3. On the track 1 processing vehicles 4 are arranged movable.

Der Boden 3 unterhalb des Gleises 1 soll maschinell ausgebaut werden. Hierzu wird entsprechend der Darstellung in Fig. 3a zunächst unterhalb des Gleises 1 ein U-förmiger Schnitt 5 durch eine entsprechende Schneidvorrichtung eingebracht. Dieser Schnitt 5 kann durch Schnittbänder mit einem Sägezahn (Fig. 4a) oder mit einem Fräskopf (Fig. 4b) erfolgen, aber auch durch eine Beaufschlagung durch Luftdruck (Fig. 4c) oder mittels Wasserstrahlen (4d).The floor 3 below the track 1 should be removed by machine. For this purpose, as shown in Fig. 3a initially introduced below the track 1, a U-shaped section 5 by a corresponding cutting device. This section 5 can be cut by cutting bands with a sawtooth ( Fig. 4a ) or with a milling head ( Fig. 4b ), but also by exposure to atmospheric pressure ( Fig. 4c ) or by means of water jets (4d).

In dem dargestellten Ausführungsbeispiel ist ein endlos umlaufendes Sägeband 8 vorgesehen, welches U-förmig geführt ist. Statt des Sägebandes 8 könnte auch ein Fräsband verwendet werden. Dies bedeutet, daß die senkrechten Schenkel des "U" den vertikalen Schnitt und die Basis des "U" den horizontalen Schnitt des insgesamt U-förmigen Schnittes 5 einbringen. Indem das endlos umlaufende Sägeband 8 U-förmig geführt ist, bedeutet dies, daß im Bereich der Basis sowie im Bereich der beiden Schenkel des U-Profils entsprechende Abschnitte des Sägebandes 8 dicht nebeneinander sowie parallel zueinander in entgegengesetzte Richtungen laufen. Selbstverständlich ist ein entsprechender Antrieb für das Sägeband 8 vorgesehen.In the illustrated embodiment, an endlessly circulating saw band 8 is provided, which is guided in a U-shape. Instead of the saw band 8 and a milling belt could be used. This means that the vertical legs of the "U" bring the vertical section and the base of the "U" the horizontal section of the total U-shaped section 5. By the endlessly circulating saw band 8 is guided U-shaped, this means that in the region of the base and in the region of the two legs of the U-profile corresponding sections of the saw band 8 run close to each other and parallel to each other in opposite directions. Of course, a corresponding drive for the saw blade 8 is provided.

Bei der Ausführungsvariante in Fig. 3b ist ebenfalls ein endlos umlaufendes Sägeband 8 vorgesehen. Dieses ist jedoch nicht in der vorbeschriebenen Weise wie ein "U" geführt, sondern in der Art eines Rechtecks mit einer Mittenöffnung. Dies bedeutet aber, daß der untere Bereich dieses Rechtecks ein U-Profil definiert, welches dem U-förmigen Schnitt 5 entspricht. Statt der rechteckigen Öffnung dieses umlaufenden Sägebandes 8 sind auch andere Profilformen denkbar.In the embodiment in Fig. 3b an endlessly circulating saw band 8 is also provided. However, this is not performed in the above manner as a "U", but in the manner of a rectangle with a central opening. This means, however, that the lower Area of this rectangle defines a U-profile, which corresponds to the U-shaped section 5. Instead of the rectangular opening of this revolving saw band 8, other profile shapes are conceivable.

Auf jeden Fall bewirkt der Schnitt 5 eine Trennung des Bodens 3 in eine obere, auszubauende Bodenschicht 6 und einem darunter befindlichen Untergrund 7. Aufgrund dieser sauberen Trennlinie kann die darüber befindliche Bodenschicht 6 maschinell gelöst und abgetragen werden, wie dies in Fig. 1 schematisch dargestellt ist.In any case, the section 5 causes a separation of the bottom 3 in an upper layer of soil 6 to be removed and an underlying surface 7. Because of this clean dividing line, the soil layer located above 6 can be mechanically detached and removed, as in Fig. 1 is shown schematically.

Während der gesamten Prozedur kann das Gleis 1 mit seinen Schwellen 2 entweder nach dem Entfernen der Bodenschicht 6 absacken oder aber das Gleis 1 mit seinen Schwellen 2 wird durch eine entsprechende Hebevorrichtung der Bearbeitungsfahrzeuge 4 gehalten.During the entire procedure, the track 1 with its sleepers 2 can either sag after the bottom layer 6 has been removed or the track 1 with its sleepers 2 is held by a corresponding lifting device of the processing vehicles 4.

Bei der zweiten Ausführungsform in den Fig. 5 bis 7 geht es nicht um den maschinellen Ausbau der Bodenschicht 6 unterhalb des Gleises 1, sondern in diesem Fall um den maschinellen Ausbau der Bodenschicht 6 neben dem Gleis 1.In the second embodiment in the Fig. 5 to 7 is not about the mechanical expansion of the soil layer 6 below the track 1, but in this case to the mechanical expansion of the soil layer 6 next to the track. 1

Die Funktionsweise ist vom Grundprinzip her die gleiche wie bei der ersten Ausführungsform, d. h. es wird ein U-förmiger Schnitt 5 in der vorbeschriebenen Weise durchgeführt, um so eine Trennung der abzutragenden Bodenschicht 6 vom Untergrund 7 zu bewirken. Anschließend wird die Bodenschicht 6 wieder maschinell gelöst und abgetragen.The operation is basically the same as in the first embodiment, d. H. a U-shaped cut 5 is made in the manner described above so as to effect a separation of the soil layer 6 to be removed from the substrate 7. Subsequently, the bottom layer 6 is again mechanically released and removed.

Bei der Ausführungsvariante in Fig. 7a ist entsprechend der Variante in Fig. 3a wiederum ein endlos umlaufendes Sägeband 8 mit einer U-förmigen Führung vorgesehen, während bei der Variante in Fig. 7b entsprechend der Variante in Fig. 3b das endlos umlaufende Sägeband 8 ein Rechteck definiert.In the embodiment in Fig. 7a is according to the variant in Fig. 3a in turn provided an endlessly circulating saw band 8 with a U-shaped guide, while in the variant in Fig. 7b according to the variant in Fig. 3b the endlessly circulating saw band 8 defines a rectangle.
