- the washing liquid released leads to considerable wetting of the tunnel floor.
- On branch lines of a rail transport network it is possible to wait until the contaminated washing liquid has seeped away.
- the contaminated washing liquid has to be collected and transported away on busy high-speed routes, which is usually done by tanker trucks.
- the wastewater logistics is quite demanding, as large amounts of wastewater have to be collected and transported away in sections of the route that are sometimes difficult to access.
- a tank truck needs several trips to remove the dirty water.
- the cleaning vehicle must be supplied with fresh water.

- the flocculation stage includes, in particular, a flocculation tank and a flocculant supply with appropriate agitators.
- the arrangement of the flocculation stage along an inner longitudinal side of the casing within a first cuboid half of the casing requires the flocculation container to be designed in which the length of the flocculation container is preferably greater than its height and the height is preferably greater than its width. In such an embodiment, the surge of the liquid in the flocculation container caused by the movement of the cleaning vehicle is also reduced.
- the flocculation tank is connected to the storage tank at its inlet and to the sedimentation stage at its outlet.

- the sedimentation container 6 is connected to a storage container 7 via a first supply line 9 for the pre-cleaned washing liquid, and the receiving container 7 is connected to the processing unit 11 via a second supply line 15 tied together.
- the supply lines 9, 15 and the return line 10 are also designed as flexible hose lines.
- a stay container 12 is also provided for the operating crew of the cleaning vehicle.
- the cleaning vehicle is also designed as a rail vehicle in which all the containers and the processing unit 11 are arranged on wagons, as in FIG Fig. 1 is shown schematically.
- the suctioned and contaminated washing liquid is from the suction hood 2 via the Hose lines 14 initially passed into the sedimentation container 6.
- a prefiltration and coarse separation takes place, in that solids settle which are heavier than water.
- the overflow water of the sedimentation container 6 represents pre-cleaned washing liquid which is pumped via a first supply line 9 into a storage container 7 for the subsequent processing unit 11.
- the storage container 7 is connected to the processing unit 11 via a second supply line 15, which comprises a flocculation stage 16 and a sedimentation stage 17 arranged downstream of the flocculation stage 16, as will be shown in the following on the basis of FIG Fig. 2 is explained.

Die Erfindung betrifft ein Reinigungsfahrzeug für Tunnel mit einem Fahrantrieb, einem Waschflüssigkeitsbehälter, und einer mit dem Waschflüssigkeitsbehälter über Zuleitungen verbundenen Reinigungseinheit mit Reinigungsbürsten und Reinigungsdüsen zur Abgabe der Waschflüssigkeit gegen die Tunnelinnenwand, wobei eine Absaugeinheit für die verschmutzte Waschflüssigkeit vorgesehen ist, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a cleaning vehicle for tunnels with a drive system, a washing liquid container, and a cleaning unit connected to the washing liquid container via feed lines with cleaning brushes and cleaning nozzles for dispensing the washing liquid against the inner wall of the tunnel, a suction unit being provided for the dirty washing liquid, according to the preamble of
Tunnelinnenwände werden im Zuge der Benutzung des Tunnels zunehmend verschmutzt und müssen in regelmäßigen Abständen gereinigt werden. Hierfür sind Reinigungsfahrzeuge bekannt, die mit Reinigungsbürsten und Reinigungsdüsen versehen sind, wobei die Reinigungsdüsen mithilfe von Hochdruckpumpen eine Waschflüssigkeit unter hohem Druck gegen die Tunnelinnenwand sprühen und die Reinigungsbürsten die Tunnelinnenwand säubern. Zur Reinigung von Eisenbahntunnels sind diese Reinigungsfahrzeuge als Schienenfahrzeuge ausgeführt. Eine gattungsgemäße Vorrichtung wurde in der

Es ist somit Ziel der Erfindung die Reinigung von Tunnelinnenwänden rascher und kostengünstiger durchführen zu können. Zudem soll ein ökonomischer Einsatz der Wachflüssigkeit ermöglicht werden.It is therefore the aim of the invention to be able to carry out the cleaning of tunnel inner walls more quickly and more cost-effectively. In addition, an economical use of the wax liquid should be made possible.
Diese Ziele werden durch die Merkmale von Anspruch 1 gelöst. Anspruch 1 bezieht sich auf ein Reinigungsfahrzeug für Tunnel mit einem Fahrantrieb, einem Waschflüssigkeitsbehälter, und einer mit dem Waschflüssigkeitsbehälter über Zuleitungen verbundenen Reinigungseinheit mit Reinigungsbürsten und Reinigungsdüsen zur Abgabe der Waschflüssigkeit gegen die Tunnelinnenwand, wobei eine Absaugeinheit für die verschmutzte Waschflüssigkeit vorgesehen ist, bei dem erfindungsgemäß vorgeschlagen wird, dass die Absaugeinheit mit einem Sedimentationsbehälter zur Vorreinigung der verschmutzten Waschflüssigkeit durch das Absetzen von Feststoffen, die schwerer als Wasser sind, verbunden ist, und der Sedimentationsbehälter über eine Zufuhrleitung zum Abpumpen des Überlaufwassers des Sedimentationsbehälters als vorgereinigte Waschflüssigkeit mit einer Aufbereitungseinheit für die vorgereinigte Waschflüssigkeit verbunden ist, die eine Flockungsstufe und eine der Flockungsstufe nachgeordnete Sedimentationsstufe umfasst, und eine Rückführungsleitung für die gereinigte Waschflüssigkeit von der Aufbereitungseinheit in den Waschflüssigkeitsbehälter vorgesehen ist.These goals are achieved by the features of
Das erfindungsgemäße Reinigungsfahrzeug sieht somit nicht nur die Sammlung und Aufbereitung der verschmutzten Waschflüssigkeit vor, sondern auch deren Wiederverwendung für die Tunnelreinigung, indem die gereinigte Waschflüssigkeit in den mit der Reinigungseinheit verbundenen Waschflüssigkeitsbehälter rückgeführt wird. Die Wiederverwendung der verschmutzten Waschflüssigkeit für die Tunnelreinigung ist aber schwierig zu bewerkstelligen, da das Schmutzwasser einer Tunnelreinigung problematische Verunreinigungen wie Betonschlämme, Bitumen, Lacke oder Kunststoffe enthalten kann, die schwer aufzubereiten sind und Dichtungen und Ventile der für die Reinigungseinheit verwendeten Hochdruckpumpen und -düsen beschädigen können. Die Aufbereitung eines solchen Schmutzwassers ist bereits unter einfachen Bedingungen schwierig und erscheint insbesondere unter den beschränkten Platzverhältnissen eines Tunnelreinigungsfahrzeuges und während steter Bewegung des Tunnelreinigungsfahrzeuges kaum möglich, zudem die Aufbereitung in einer zur Wiederverwendung mit Hochdruckpumpen und -düsen ausreichenden Qualität erfolgen muss. Erfindungsgemäß wird die Wiederverwendung der verschmutzten Waschflüssigkeit mithilfe einer Kombination eines Sedimentationsbehälters und einer Aufbereitungseinheit mit einer Flockungsstufe und einer der Flockungsstufe nachgeordneten Sedimentationsstufe bewerkstelligt. Im Sedimentationsbehälter setzen sich Feststoffe ab, die schwerer als Wasser sind. Das Überlaufwasser kann abgepumpt werden und stellt vorgereinigte Waschflüssigkeit dar, die aber noch nicht für die Hochdruckpumpen und -düsen der Reinigungseinheit verwendet werden kann, wie der Anmelder festgestellt hat. Erfindungsgemäß ist daher eine Aufbereitungseinheit mit einer Flockungsstufe und einer der Flockungsstufe nachgeordneten Sedimentationsstufe vorgesehen, mit der kolloidale Feststoffe entfernt werden können. Erst das Überlaufwasser der der Flockungsstufe nachgeordneten Sedimentationsstufe verfügt über die erforderliche Reinheit, um in den Waschflüssigkeitsbehälter der Reinigungseinheit gepumpt werden zu können.The cleaning vehicle according to the invention thus not only provides for the collection and processing of the soiled washing liquid, but also its reuse for tunnel cleaning, in that the cleaned washing liquid is returned to the washing liquid container connected to the cleaning unit. The reuse of the dirty washing liquid for tunnel cleaning is difficult to accomplish, however, since the dirty water of tunnel cleaning is problematic Contains contaminants such as concrete slurry, bitumen, paint or plastics that are difficult to process and can damage the seals and valves of the high-pressure pumps and nozzles used for the cleaning unit. The treatment of such wastewater is difficult even under simple conditions and seems hardly possible, especially under the limited space of a tunnel cleaning vehicle and while the tunnel cleaning vehicle is constantly moving, and the treatment must be of a quality sufficient for reuse with high-pressure pumps and nozzles. According to the invention, the dirty washing liquid is reused with the aid of a combination of a sedimentation container and a processing unit with a flocculation stage and a sedimentation stage downstream of the flocculation stage. Solids that are heavier than water are deposited in the sedimentation tank. The overflow water can be pumped out and represents pre-cleaned washing liquid, which, however, cannot yet be used for the high-pressure pumps and nozzles of the cleaning unit, as the applicant has established. According to the invention, a processing unit with a flocculation stage and a sedimentation stage downstream of the flocculation stage is therefore provided, with which colloidal solids can be removed. Only the overflow water of the sedimentation stage downstream of the flocculation stage has the required purity to be able to be pumped into the washing liquid container of the cleaning unit.
Um die Flockungsstufe optimal betreiben zu können wird ferner vorgeschlagen, dass der Sedimentationsbehälter über eine erste Zufuhrleitung für die vorgereinigte Waschflüssigkeit mit einem Vorlagebehälter verbunden ist, und der Vorlagebehälter über eine zweite Zufuhrleitung mit der Aufbereitungseinheit verbunden ist. Auf diese Weise kann die Aufbereitungseinheit unabhängig von der im Sedimentationsbehälter augenblicklich anfallenden Schmutzwassermenge betrieben werden, wodurch insbesondere der Betrieb der Flockungsstufe und die Dosierung des Flockungsmittels erleichtert wird.In order to be able to operate the flocculation stage optimally, it is also proposed that the sedimentation tank is connected to a storage tank via a first supply line for the pre-cleaned washing liquid, and the storage tank is connected to the processing unit via a second supply line. In this way, the treatment unit can be operated independently of the amount of dirty water that is currently occurring in the sedimentation tank, as a result of which in particular, the operation of the flocculation stage and the dosing of the flocculant is facilitated.
Des Weiteren wird vorgeschlagen, dass die Aufbereitungseinheit eine der Sedimentationsstufe nachgeordnete Filterstufe umfasst. Hierfür kann eine der Sedimentationsstufe nachgeordnete Druckerhöhungspumpe vorgesehen sein, um die Filterstufe optimal betreiben zu können. Mit der Filterstufe können im Überlauf der Sedimentationsstufe verbliebene Feststoffe entfernt werden. Die Zusammenstellung der Filterstufe kann variieren, vorzugsweise werden etwa Sandfilter und/oder Beutelfilter verwendet. Sand- und Beutelfilter sind einfach aufgebaute Filter, die zur Endfiltration bei sehr geringen Feststoffkonzentrationen eingesetzt werden können. Aber auch Ionentauscher, Aktivkohlefilter oder Vorrichtungen zur UV-Entkeimung können vorgesehen sein.It is also proposed that the processing unit include a filter stage downstream of the sedimentation stage. For this purpose, a pressure increasing pump arranged downstream of the sedimentation stage can be provided in order to be able to operate the filter stage optimally. With the filter stage remaining solids in the overflow of the sedimentation stage can be removed. The composition of the filter stage can vary, for example sand filters and / or bag filters are preferably used. Sand and bag filters are simple filters that can be used for final filtration at very low solids concentrations. But ion exchangers, activated carbon filters or devices for UV disinfection can also be provided.
Hinsichtlich der baulichen Verwirklichung der Aufbereitungseinheit unter den beschränkten Platzverhältnissen eines bewegten Reinigungsfahrzeuges wird vorgeschlagen, dass die Aufbereitungseinheit eine quaderförmige Ummantelung aufweist, wobei sich die Flockungsstufe entlang einer inneren Längsseite der Ummantelung innerhalb einer ersten Quaderhälfte erstreckt, und sich die Sedimentationsstufe entlang einer inneren Breitseite der Ummantelung erstreckt. Die Aufbereitungseinheit kann mit ihrer quaderförmigen Umhüllung etwa auf einen Waggon eines Schienenfahrzeuges gestellt werden. Die Flockungsstufe umfasst insbesondere einen Flockungsbehälter und eine Flockungsmittelzufuhr mit entsprechenden Rührwerken. Die Anordnung der Flockungsstufe entlang einer inneren Längsseite der Ummantelung innerhalb einer ersten Quaderhälfte der Umhüllung bedingt eine Ausführung des Flockungsbehälters, bei der die Länge des Flockungsbehälters vorzugsweise größer ist als seine Höhe, und die Höhe vorzugsweise größer ist als seine Breite. Bei einer solchen Ausführung wird auch die durch die Bewegung des Reinigungsfahrzeuges verursachte Schwallbewegung der im Flockungsbehälter befindlichen Flüssigkeit verringert. Der Flockungsbehälter ist an seinem Einlauf mit dem Vorlagebehälter verbunden, und an seinem Auslauf mit der Sedimentationsstufe. Die Filterstufe kann entlang einer inneren Längsseite der Ummantelung innerhalb einer zweiten Quaderhälfte angeordnet werden, sodass der quaderförmige Innenraum der Aufbereitungseinheit optimal genutzt wird.With regard to the structural implementation of the treatment unit under the limited space of a moving cleaning vehicle, it is proposed that the treatment unit have a cuboid casing, the flocculation stage extending along an inner longitudinal side of the casing within a first cuboid half, and the sedimentation stage extending along an inner broad side of the casing extends. The processing unit with its cuboid casing can be placed on a wagon of a rail vehicle, for example. The flocculation stage includes, in particular, a flocculation tank and a flocculant supply with appropriate agitators. The arrangement of the flocculation stage along an inner longitudinal side of the casing within a first cuboid half of the casing requires the flocculation container to be designed in which the length of the flocculation container is preferably greater than its height and the height is preferably greater than its width. In such an embodiment, the surge of the liquid in the flocculation container caused by the movement of the cleaning vehicle is also reduced. the The flocculation tank is connected to the storage tank at its inlet and to the sedimentation stage at its outlet. The filter stage can be arranged along an inner longitudinal side of the casing within a second cuboid half, so that the cuboid interior of the processing unit is optimally used.
Da das Schmutzwasser eine Verschiebung des pH-Wertes verursacht, die den anschließenden Reinigungsprozess sowie nachfolgende Anlagenteile wie Pumpen und Düsen beeinträchtigen kann, wird ferner vorgeschlagen, dass die Aufbereitungseinheit eine Einrichtung zur pH-Neutralisierung der Waschflüssigkeit aufweist.Since the dirty water causes a shift in the pH value, which can affect the subsequent cleaning process and subsequent system parts such as pumps and nozzles, it is also proposed that the treatment unit have a device for pH neutralization of the washing liquid.
Hinsichtlich der Sedimentationsstufe wird vorgeschlagen, dass sie als Lamellenklärer ausgeführt ist. Lamellenklärer weisen im Bodenbereich mehrere parallel angeordnete, schräg stehende Platten auf, um den Sedimentationsbereich im Verhältnis zum zur Verfügung stehenden Platz zu maximieren, was sich unter den gegebenen beschränkten Platzverhältnissen als sehr vorteilhaft erweist.With regard to the sedimentation stage, it is proposed that it be designed as a lamella clarifier. In the bottom area, lamellar clarifiers have several parallel, inclined plates in order to maximize the sedimentation area in relation to the available space, which proves to be very advantageous given the limited space available.
Zudem wird vorgeschlagen, dass die Absaugeinheit als eine in Fahrtrichtung gesehen nach der Reinigungseinheit angeordnete Absaughaube ausgeführt ist. Die mit dem Sedimentationsbehälter verbundene Absaugeinheit befindet sich somit im unmittelbaren Aussprühbereich der Waschflüssigkeit und kann somit eine maximale Menge der versprühten Waschflüssigkeit erfassen.It is also proposed that the suction unit be designed as a suction hood arranged after the cleaning unit as seen in the direction of travel. The suction unit connected to the sedimentation container is thus located in the immediate spraying area of the washing liquid and can thus capture a maximum amount of the sprayed washing liquid.

Das Überlaufwasser des Sedimentationsbehälters 6 stellt vorgereinigte Waschflüssigkeit dar, die über eine erste Zufuhrleitung 9 in einen Vorlagebehälter 7 für die nachfolgende Aufbereitungseinheit 11 gepumpt wird.As already mentioned, the suctioned and contaminated washing liquid is from the
Der Vorlagebehälter 7 ist über eine zweite Zufuhrleitung 15 mit der Aufbereitungseinheit 11 verbunden, die eine Flockungsstufe 16 und einer der Flockungsstufe 16 nachgeordnete Sedimentationsstufe 17 umfasst, wie in weiterer Folge anhand der
Die nachfolgende Sedimentationsstufe 17 dient der Sedimentation der in der Flockungsstufe 16 gebildeten Flocken und ist vorzugsweise als Lamellenklärer ausgeführt. Im Bodenbereich der Sedimentationsstufe 17 ist eine Schlammaustragungspumpe 21 angeordnet, um den abgesetzten Schlamm zu entfernen. Die gereinigte Waschflüssigkeit aus der Sedimentationsstufe 17 wird in weiterer Folge einem Vorlagebecken 30 mit einer Druckerhöhungspumpe 31 für eine nachfolgende Filterstufe 22 zugeführt. Die Filterstufe 22 dient der Endfiltration und umfasst im gezeigten Ausführungsbeispiel der

Das erfindungsgemäße Reinigungsfahrzeug sieht somit nicht nur die Sammlung und Aufbereitung der verschmutzten Waschflüssigkeit vor, sondern auch deren Wiederverwendung für die Tunnelreinigung, indem die gereinigte Waschflüssigkeit aus der Aufbereitungseinheit 11 wieder in den mit der Reinigungseinheit 1 verbundenen Waschflüssigkeitsbehälter 8 rückgeführt wird. Zur Wiederverwendung der verschmutzten Waschflüssigkeit für die Tunnelreinigung wird die verschmutzte Waschflüssigkeit mithilfe einer Kombination eines Sedimentationsbehälters 6 und einer Aufbereitungseinheit 11 mit einer Flockungsstufe 16 und einer der Flockungsstufe 16 nachgeordneten Sedimentationsstufe 17 zur Entfernung kolloidaler Feststoffe bewerkstelligt. Das Überlaufwasser der der Flockungsstufe 16 nachgeordneten Sedimentationsstufe 17 verfügt über die erforderliche Reinheit, um in den Waschflüssigkeitsbehälter 8 der Reinigungseinheit 1 gepumpt werden zu können und mit den Hochdruckpumpen und -düsen der Reinigungseinheit 1 verwendet werden zu können. Nach der Tunnelreinigung müssen lediglich die abgesetzten Feststoffe des Sedimentationsbehälters 6, sowie der ausgetragene Schlamm der Sedimentationsstufe 7 abgepumpt und entsorgt werden, sowie fehlende Waschflüssigkeit ergänzt werden, was aber fernab des gereinigten Tunnels und somit unter einfachen Betriebsbedingungen erfolgen kann. Der Transport von verschmutzter Waschflüssigkeit über Tanklastwagen sowie die laufende Bereitstellung frischer Waschflüssigkeit kann vollständig entfallen, wodurch die Reinigung von Tunnelinnenwänden rascher und kostengünstiger durchgeführt werden kann. Zudem wird ein ökonomischer Einsatz der Wachflüssigkeit erreicht.The cleaning vehicle according to the invention thus not only provides for the collection and processing of the soiled washing liquid, but also its reuse for tunnel cleaning by removing the cleaned washing liquid the
