Abstract

Disclosed is a method that is carried out by means of railway vehicles (1, 2) which are each provided with a trough-shaped container that is open at the top. The containers (8) can be filled when the train moves slowly, whereupon the concrete is transported. The concrete is prevented from separating in the trough-shaped containers (8) by means of a stirring apparatus (18) during travel. In order to unload the concrete, the railway vehicles are pulled together by means of the couplings (24, 25) thereof such that the individual containers (8) are sealingly connected. The sliding openings in the end walls (11, 12) of the containers are then opened, and the conveyor system (18) conveys the concrete forward from one container (8) to another (8) to the front of the train, where the concrete is discharged through the forward end wall opening of the container (8) of the front railway vehicle (1) into the hopper of a concrete pump via a belt conveyor or into concrete hauling cars that convey the concrete directly into a concrete pump.

Description

Diese Erfindung betrifft ein Verfahren für den Betontransport auf Schienen, sowie eine Vorrichtung zur Durchführung des Verfahrens. Der Transport von grossen Mengen von Beton ist vor allem im Strassenbau, Brückenbau und ganz besonders im Tunnelbau gefordert.This invention relates to a railroad concrete transport method and apparatus for carrying out the method. The transport of large quantities of concrete is required above all in road construction, bridge construction and especially in tunnel construction.

Im Tunnelbau zum Beispiel werden pro Laufmeter Tunnelschalung in der Grössenordnung ca. 10m3 Beton benötigt. Um diese Mengen anzutransportieren, wird, sofern die Versorgung nicht mit Strassentransportfahrzeugen erfolgt, herkömmlich ein Zug aus Trommelwagen eingesetzt. Mit dem Tunnelvortrieb werden nach und nach Schienen verlegt, sodass ein solcher Transportzug auf diesen Schienen von ausserhalb des Tunnels, wo er mit Beton beladen wird, mit seiner Zugspitze bis zur Tunnelbrust vorfahren kann. Der Beton wird jeweils zuvorderst, an der Brust des vorzutreibenden Tunnels, verbaut. Die einzelnen Trommelwagen fassen bis zu 30m3 und ein Zug besteht aus mehreren Wagen. Ein solcher Zug fährt dann in einer Tagesschicht je nach Bedarf und Tunnellänge beispielsweise zwei bis dreimal in den Tunnel hinein.In tunnel construction, for example, approximately 10m 3 of concrete is required per linear meter of tunnel formwork. In order to transport these quantities, unless the supply is provided by road transport vehicles, a train of drum cars is conventionally used. With the tunneling progressively rails are laid, so that such a transport train on these rails from outside the tunnel, where it is loaded with concrete, with its Zugspitze can drive up to the tunnel breast. The concrete is installed in each case at the very front, on the chest of the vorzutreibenden tunnel. The individual drum cars can hold up to 30m 3 and a train consists of several cars. Such a train then travels in a day shift as needed and tunnel length, for example, two to three times in the tunnel.

Sobald der Beton ausserhalb des Tunnels auf die Bahnwagen verladen ist, muss sichergestellt werden, dass keine Entmischung des Betons stattfindet und dieser auch nicht vorzeitig abbindet. Die Abbindung ist ein chemisch ablaufender Prozess, dessen zeitlicher Verlauf unter anderem temperaturabhängig ist, weswegen er je nach den Verhältnissen wenn nötig durch die Zugabe von Verzögerungsmitteln hinausgezögert oder mit Beschleunigungsmitteln verkürzt wird. Eine weitere Massnahme, um das Entmischen zu verhindern, besteht darin, den Beton laufend in Bewegung zu halten.Once the concrete has been loaded onto the railcars outside the tunnel, it must be ensured that there is no segregation of the concrete and that it does not prematurely set. The setting is a chemical process Process whose course over time is inter alia temperature-dependent, which is why, depending on the circumstances, it is delayed by the addition of retardants, if necessary, or shortened with accelerating agents. Another measure to prevent segregation is to keep the concrete moving.

Herkömmliche Transportzüge bestehen deshalb aus Eisenbahnwagen, auf denen je eine zigarrenförmige Trommel liegend installiert ist, sodass sie sich über die ganze Länge des Wagens erstreckt, und die sich mittels eines Antriebs laufend um ihre horizontale Achse dreht. Zigarrenförmig sind die Trommeln deswegen, weil sie sich an beiden Enden etwas verjüngen und dann in eine offene Mündung auslaufen. Die Mündung an jenem Ende der Trommel, das der Tunnelbrust zugewandt ist oder in Transportrichtung zeigt, ragt in die etwas grössere hintere Trommelmündung auf dem nach vorne nächsten Wagen. Die vorderen Mündungen ragen also bei aneinander gekoppelten Wagen jeweils in die hinteren Mündungen der Vorderwagen hinein. Durch das Rotieren der Trommeln wird der darin liegende Beton laufend umgeschlagen und mechanisch in Bewegung gehalten. Damit der Beton innerhalb der einzelnen Wagen transportierbar und somit entladbar ist, sind im Innern der Trommeln schraubenlinienförmig angeordnete Rippen vorhanden. Durch die Drehung der Trommeln in der einen Drehrichtung wird der Beton einerseits in Bewegung gehalten, andrerseits aber auch durch Drehung in der anderen Richtung in Zusammenwirkung mit den Rippen stetig nach vorne verschoben. Die Trommeln sind auf Wälzlagern gelagert, die sich an bestimmten Stellen am Wagenchassis finden. An den Abrollstellen der Trommeln müssen diese aussen über den ganzen Umfang glatt ausgeführt sein. Nur an zwischenliegenden Stellen sind Öffnungen in den Trommeln zum Befüllen vorhanden. Diese sind mit einem Mannsloch vergleichbar und von speziellen Deckeln dicht verschliessbar. Die Deckel wiegen dabei um die 300kg bis 400kg, denn sie müssen ja, wenn sie sich infolge der Rotation der Trommeln gerade unten befinden, die Last des auf ihrer Innenseite liegenden Betons tragen. Sie weisen denn auch einen speziellen Schliessmechanismus auf, der das sicherstellt. Damit eine einzelne Trommel mit Beton befüllt werden kann, muss zunächst sichergestellt werde, dass sich die Öffnungen oben im jeweiligen Zenit der Trommel befinden. Dann müssen die Öffnungen freigelegt werden, indem die Deckel gelöst und weggehoben werden. Hierzu wird eine eigens dafür gestaltete Deckelmaschine eingesetzt, die vor dem Portal der Betonanlage aufgestellt ist, an welcher die Trommeln befüllt werden. Die Deckel können aufgrund ihrer Grösse und ihres Gewichtes nämlich nicht von Menschenhand weggehoben werden. Die weggehobenen Deckel müssen zwischengelagert werden und nach dem Befüllen mit Beton wieder auf das zugehörige Loch in der Trommel aufgesetzt und dichtend verschlossen werden. Hierfür muss der Zug nach dem Befüllen wieder vom Betonsilo aus rückwärts fahren; an der Deckelmaschine vorbei, wo das anlässlich eines abermaligen, örtlich definierten Zwischenstopps geschieht.Conventional transport trains are therefore made of railway cars, on each of which a cigar-shaped drum is installed horizontally so that it extends over the entire length of the carriage, and which rotates by means of a drive continuously about its horizontal axis. The drums are cigar-shaped because they rejuvenate slightly at both ends and then run out into an open mouth. The mouth at that end of the drum, which faces the tunnel breast or points in the direction of transport, protrudes into the slightly larger rear drum mouth on the next carriage to the front. The front orifices thus protrude into each other in the rear mouths of the front car in coupled cars. By rotating the drums, the concrete inside is constantly being turned over and mechanically held in motion. So that the concrete is transportable and thus dischargeable within the individual carriages, spirally arranged ribs are present in the interior of the drums. By the rotation of the drums in one direction of rotation of the concrete is held on the one hand in motion, on the other hand but also moved by rotation in the other direction in cooperation with the ribs steadily forward. The drums are mounted on rolling bearings, which can be found at certain locations on the carriage chassis. At the unwinding of the drums they must be made smooth outside over the entire circumference. Only at intermediate points openings are present in the drums for filling. These are comparable to a manhole and can be closed tightly by special lids. The lids weigh around 300kg to 400kg, because they have to be, if they are just below due to the rotation of the drums, the load of lying on its inside concrete. They also have a special locking mechanism that ensures this. In order for a single drum to be filled with concrete, it must first be ensured that the openings are at the top in the respective zenith of the drum. Then the openings must be uncovered by loosening the lids and lifting them off. For this purpose, a specially designed lidding machine is used, which is placed in front of the portal of the concrete plant, where the drums are filled. Because of their size and weight, the lids can not be lifted by human hands. The lifted lids must be stored temporarily and placed back on the associated hole in the drum after filling with concrete and sealed. To do this, the train must drive backwards from the concrete silo after filling; past the lid machine, where this happens on the occasion of a repeated, locally defined stopover.

Das eigentliche Befüllen einer Trommel erfolgt, indem mit dem Zug unter einem Betonsilo durchgefahren wird und wenn jeweils die Öffnung einer Trommel unter die Ausschüttgosse des Betonsilos zu liegen kommt, der Zug angehalten wird. Dann wird die Ausschüttgosse geöffnet und eine Charge Beton wird in die Trommel geschüttet. Hernach wird mit dem Zug ein stückweit vorgefahren, bis die nächste Trommelöffnung sich unter der Ausschüttgosse befindet, usw., bis schliesslich die Trommelwagen des ganzen Zuges beladen sind. Danach wird der ganze befüllte Zug zurückgefahren und bei der Deckelmaschine wird jede einzelne Öffnung durch Anhalten des Zuges und Betätigen der Deckelmaschine verschlossen.The actual filling of a drum is carried out by passing the train under a concrete silo and when each of the opening of a drum comes to rest under the pouring spout of the concrete silo, the train is stopped. Then the discharge gutter is opened and a batch of concrete is poured into the drum. Thereafter, the train is pulled forward a bit, until the next drum opening is below the discharge, etc., until finally the drum cars of the whole train are loaded. Thereafter, the whole filled train is moved back and the lid machine, each individual opening is closed by stopping the train and operating the lid machine.

Der befüllte Zug fährt hernach gestossen von einer Lokomotive in den Tunnel hinein, unter ständiger Drehung der Tommeln auf den einzelnen Wagen. Am Ziel angelangt, wird der Beton vorne am vordersten Wagen entnommen, wo er aus der dortigen Trommelmündung herausfällt. Durch das Drehen der Trommeln wird der Beton in den einzelnen Trommeln nämlich stetig nach vorne gefördert, von Trommel zu Trommel, bis er schliesslich aus der vordersten Trommel ausgeschüttet wird und dann der Verarbeitung im Bereich der Tunnelbrust zugeführt werden kann. Aus US 5 335 990 A (MAXON III GLENWAYS W [US] ist ein Verfahren und eine Vorrichtung für den Betontransport auf Schienen bekannt. Die Vorrichtung dazu besteht aus Schienenfahrzeugen mit je oben offenen trogförmigen Behältern, wobei In jedem offenen trogförmigen Behälter ein Rühr- und Förderwerk angeordnet ist, mittels dessen der inliegende Beton mischbar und aus einer Öffnung des Behälters förderbar ist. Die Behälter können während der Fahrt von oben aus einem Betonsilo befüllt werden. Gemäss dem Verfahren wird der Beton beim Transport auf den Schienen in den offenen, trogförmigen Behältern durch Rühren mit einem Rührwerk vor der Entmischung geschützt. Zum Entladen wird der Beton durch das Rühr- und Förderwerk von einem Behälter aufwärts und dann von oben in den nächstfolgenden Behälter gefördert und schliesslich aus dem vordersten Schienenfahrzeuges nach oben und dann auf einen Beschicktrichter einer Betonpumpe gefördert. Die Vorrichtungen zum Fördern des Betons vom einen Behälter zum nächsten und schliesslich vom vordersten Behälter in den Beschicktrichter sind jedoch aufwändig konstruiert und nehmen viel Platz ein. Aus WO90/08021 A (MINKKINNEN RISTO [FI]) ist ein Verfahren und eine Vorrichtung für den Betontransport auf Schienen bekannt, wobei zum Entladen die Behälter der aufeinanderfolgenden Schienenfahrzeuge durch Zusammenziehen der Kupplungen dichtend miteinander verbunden werden. An den endseitigen Stirnwänden der Behälter sind hierzu Schieber- oder Klappenöffnungen vorhanden. Diese bekannten Behälter sind jedoch geschlossene rohrförmige Trommeln, die sich zum Rühren und Fördern des Betons als Ganzes drehen.Afterwards, the filled train, driven by a locomotive, enters the tunnel, constantly turning the drums on the individual wagons. Arrived at the destination, the concrete is taken from the front of the foremost car, where it falls out of the drum mouth. By rotating the drums, the concrete in the individual drums is conveyed steadily forward, from drum to drum, until it is finally released from the foremost drum and then fed to the processing in the area of the tunnel breast. Out US 5 335 990 A (MAXON III GLENWAYS W [US] discloses a method and apparatus for railroad concrete transport, the apparatus of which consists of rail vehicles with trough-shaped containers open at the top, wherein in each open trough-shaped container there is a stirring device. and conveyor is arranged, by means of which the in-lying concrete is miscible and can be conveyed from an opening of the container. The containers can be filled while driving from the top of a concrete silo. According to the method, the concrete is protected against segregation during transport on the rails in the open, trough-shaped containers by stirring with a stirrer. For unloading the concrete is conveyed by the stirring and conveyor of a container upwards and then from the top of the next container and finally promoted from the foremost rail vehicle upwards and then to a feed hopper of a concrete pump. However, the devices for conveying the concrete from one container to the next and finally from the foremost container into the feed hopper are elaborately constructed and take up a lot of space. Out WO90 / 08021 A (MINKKINNEN RISTO [FI]) a method and a device for concrete transport on rails is known, wherein for unloading the containers of the successive rail vehicles are sealed together by contracting the couplings. At the end-side end walls of the container slide or flap openings are available for this purpose. However, these known containers are closed tubular drums which rotate to agitate and convey the concrete as a whole.

Die Nachteile dieser Lösungen und vor allem jener mit den bisher weit verbreiteten Trommelwagen, die sozusagen zu einer Standard-Ausrüstung im Tunnelbau geworden sind, lassen sich wie folgt umschreiben:

  1. 1. Die pro Zeit antransportierbare Betonmenge ist ziemlich beschränkt, weil der Zug für das Reinigen und erneute Befüllen zu lange stehen muss. Die Transportkapazität des Systems ist daher zu gering und schafft auf der Baustelle Engpässe.
  2. 2. Die Trommelwagen müssen für das Befüllen mittels einer speziellen Deckelmaschine vorbereitet werden. Hierzu ist also zunächst eine solche Anlage nötig, und dann muss der Zug jeweils an der richtigen Stelle angehalten werden, wonach diese Entdeckelung und Zwischenlagerung der Deckel erfolgt. Das ist ein umständliches und zeitraubendes Prozedere. Die Deckelmaschine benötigt nicht wenig Platz vor dem Tunnelportal. Vor Tunnelportalen steht aber in den meisten Fällen wenig Platz zur Verfügung.
  3. 3. Der Zug muss mit den einzelnen Trommelöffnungen genau unter der Ausschüttgosse des Betonsilos angehalten werden. Aufgrund der vergleichsweise kleinen Öffnung in der Trommelwand dauert der Füllvorgang verhältnismässig lange. Jede Trommel verfügt über zwei Öffnungen. Entsprechend muss der Zug pro Trommel zweimal an genau definierter Stelle angehalten werden.
  4. 4. Nach dem Befüllen müssen die Deckel mittels der Anlage wieder aufgesetzt und dicht verschlossen werden. Der Zug muss wiederum mit jeder Trommelöffnung bei der Deckelmaschine positioniert viele Male angehalten werden. Insgesamt geht das Befüllen zu langsam vonstatten und ist für die operative Abwicklung kompliziert.
  5. 5. Wenn beim Entladen kein Beton mehr aus der vordersten Trommel kommt, kann man nicht sicher sein, dass alle Trommeln tatsächlich leer sind, denn deren Inneres ist uneinsehbar. Oftmals kommt nach längerem Rotieren wieder eine Charge mit Verspätung doch noch nach vorne, weil sich etwa eine Anbackung wieder gelöst hat. Ein Nachteil ist also, dass man keine Informationen über den augenblicklichen Füllstand hat. Dieser kann einzig aufgrund der bereits entnommenen Menge abgeschätzt werden.
  6. 6. Nach jedem Lade- und Entladevorgang müssen die Trommeln innen gereinigt werden, um sonst immer weiterschreitende Anbackungen zu vermeiden. Hierzu werden die Trommeln von vorne mit einem Schlauch mit Spritzwasser gefüllt und gedreht, was darin verbliebene Betonreste lösen soll. Oftmals reicht das aber nicht aus, und man stellt fest, dass sich grössere Anbackungen gebildet haben. In diesem Fall muss ein Mann durch eine geöffnete Trommellucke einsteigen und mit Hammer und Meissel oder mit einem Presslufthammer die Anbackungen mechanisch lösen, ehe dieselben herausgefördert werden können. -
  7. 7. Im Falle einer Havarie, wenn also aus irgendeinem Grund vorne kein Beton mehr entnommen werden kann, zum Beispiel infolge eines defekten Antriebs, einer defekten Betonpumpe im Verarbeitungsbereich usw., muss der Zug rasch aus dem Tunnel gefahren werden und der geladene Beton muss durch weiteres Drehen der Trommeln raschmöglichst entladen werden, damit er nicht in den Trommeln abbindet. In solchen Fällen zwangsweise entladener Beton muss als Bauschutt entsorgt werden. Nun kommt es vor, dass der Beton nicht rasch genug aus den Trommeln herausgefördert werden kann. In solchen Fällen kommt es vor, dass grosse Anbackungen im Trommelinnern sogar losgesprengt werden müssen. Das ist dann sehr aufwändig und zeitraubend, denn es müssen zunächst einige Sprenglöcher in die Anbackungen gebohrt werden, und es muss eine nach allen Regeln der Kunst angelegte Sprengung durchgeführt werden, ehe die dann losen Brocken durch erneutes Drehen der Trommeln nach vorne aus denselben gefördert werden und als Bauschutt entsorgt werden können.
The disadvantages of these solutions, and especially those with the previously widespread drum car, which have become a standard equipment in tunneling, can be described as follows:
  1. 1. The amount of concrete that can be transported per time is rather limited because the train must be left standing for cleaning and refilling too long. The transport capacity of the system is therefore too low and creates bottlenecks on the construction site.
  2. 2. The drum carts must be prepared for filling by means of a special lidding machine. For this purpose, such a system is first necessary, and then the train must be stopped in each case at the right place, after which this decapping and intermediate storage of the lid is done. This is a cumbersome and time-consuming procedure. The lid machine does not need a little space in front of the tunnel portal. But before tunnel portals is in the In most cases, little space is available.
  3. 3. The train must be stopped with the individual drum openings just under the pouring spout of the concrete silo. Due to the comparatively small opening in the drum wall, the filling process takes a relatively long time. Each drum has two openings. Accordingly, the train per drum must be stopped twice at a precisely defined point.
  4. 4. After filling, the covers must be replaced by means of the system and sealed tightly. In turn, the train must be stopped many times with each drum opening positioned at the lidding machine. Overall, the filling is too slow and is complicated for operational management.
  5. 5. If there is no more concrete coming out of the frontmost drum during unloading, you can not be sure that all the drums are actually empty because their interior is invisible. Often comes after prolonged rotation again a batch with delay but still forward because about a caking has resolved again. A disadvantage is that you have no information about the current level. This can only be estimated on the basis of the quantity already taken.
  6. 6. After each loading and unloading process, the drums must be cleaned internally, in order to avoid further progressive caking. For this purpose, the drums are filled from the front with a hose with splash water and rotated, which is to solve remaining concrete remains. Often, however, this is not enough, and it is found that larger cakes have formed. In this case, a man has to get in through an open drum lump and mechanically loosen the caking with a hammer and chisel or with a jackhammer before they can be conveyed out. -
  7. 7. In the event of an accident, for example, if for some reason no more concrete can be removed, for example due to a defective drive, a defective concrete pump in the processing area, etc., the train must be quickly driven out of the tunnel and the loaded concrete must pass through continue rotating the drums as quickly as possible so that they do not set in the drums. In such cases, forcibly discharged concrete must be considered Building rubble to be disposed of. Now it happens that the concrete can not be pumped out of the drums quickly enough. In such cases it happens that large caking in the interior of the drum even need to be blown off. This is then very time-consuming and time-consuming, because it must first be drilled some holes in the caking, and it must be carried out according to all the rules of art blasting, before the then loose chunks are conveyed by turning the drums forward again from the same and can be disposed of as rubble.

Die Aufgabe dieser Erfindung ist es, ein Verfahren für den Betontransport auf Schienen, sowie eine Vorrichtung zur Durchführung des Verfahrens anzugeben, mit denen die oben aufgeführten Nachteile vermieden werden und insgesamt praktischer, gezielter, rascher und kostengünstiger grössere Mengen von Beton pro Zeit an eine Tunnelbrust transportierbar sind.The object of this invention is to provide a method for concrete transport on rails, as well as an apparatus for performing the method, which avoids the disadvantages listed above and overall practical, targeted, faster and cheaper larger amounts of concrete per time to a tunnel breast are transportable.

Diese Aufgabe wird gelöst von einem Verfahren für den Betontransport auf Schienen, bei dem der Beton in Schienenfahrzeugen mit je einem oben offenen trogförmigen Behälter nach Befüllen der Behälter während der Fahrt von oben aus einem Betonsilo heraus hernach schienentransportiert wird, wobei der Beton in den offenen, trogförmigen Behältern durch Rühren mit einem Rührwerk vor der Entmischung geschützt wird, dadurch gekennzeichnet, dass zum Entladen der mit je einer Schieber- oder Klappenöffnung in den endseitigen Stirnwänden ausgerüsteten Behälter der aufeinanderfolgenden Schienenfahrzeuge durch Zusammenziehen der Kupplungen dichtend miteinander verbunden werden, und dass hernach Beton durch das Rühr- und Förderwerk von einem Behälter in den nächstfolgenden Behälter gefördert wird und schliesslich aus der Stirnwandöffnung des vordersten Schienenfahrzeuges auf einen Förderbandwagen und dann in den Beschicktrichter einer Betonpumpe gefördert wird.This object is achieved by a method for transporting concrete on rails, in which the concrete in rail vehicles, each with an open-topped trough-shaped container after filling the container while driving from the top of a concrete silo out after seemed transported, the concrete in the open, trough-shaped containers is protected by agitating with a stirrer before segregation, characterized in that for discharging each equipped with a slide or flap opening in the end-side end walls container of the successive rail vehicles by contracting the couplings are sealingly connected to each other, and that afterwards concrete by the stirring and conveying is promoted by a container in the next container and finally is conveyed from the end wall opening of the foremost rail vehicle on a conveyor belt trolley and then into the feed hopper of a concrete pump.

Die Aufgabe wird weiter gelöst von einer Vorrichtung für den Betontransport auf Schienen, bestehend aus Schienenfahrzeugen mit je einem oben offenen trogförmigen Behälter, wobei im offenen trogförmigen Behälter ein Rühr- und Förderwerk angeordnet ist, mittels dessen der inliegende Beton mischbar ist, dadurch gekennzeichnet, dass in jeder endseitigen Stirnwand der Behälter eine Schieber- oder Klappenöffnung vorhanden ist, durch welche der Beton mittels des Rühr- und Förderwerk des betreffenden Behälters förderbar ist.The object is further solved by a device for concrete transport on rails, consisting of rail vehicles, each with a open trough-shaped container, wherein in the open trough-shaped container, a stirring and conveyor is arranged, by means of which the underlying concrete is miscible, characterized in that in each end-side end wall of the container a slide or flap opening is present, through which the concrete by means of Stirring and conveying of the relevant container is eligible.

In den Zeichnungen wird diese Vorrichtung in verschiedenen Ansichten dargestellt. Ihr Aufbau und ihre Konstruktion wird im Folgenden anhand dieser Zeichnungen beschrieben und das damit betriebene Verfahren wird erläutert.

Die Figur 1 zeigt zwei Schienenfahrzeuge 1,2 einer Zugskomposition, die zum Beispiel standardmässig auf Schienen der Spurbreite 900mm verkehren. Die Förderrichtung des Betons folgt hierbei dem unter der Zugskomposition eingezeichneten Pfeil. Die Spitze des Zuges bildet also der Wagen 1, welcher zuerst in den Tunnel einfährt, während die Komposition von hinten, das heisst von den hinter dem Wagen 2 angekoppelten Wagen und der zuhinderst angekuppelten Lokomotive gestossen wird. Es versteht sich, dass eine solche Komposition aus einem halben Dutzend oder noch mehr Wagen zusammengestellt werden kann. Jedes einzelne Schienenfahrzeug 1,2 besteht aus einem Chassis 3 in Form einer selbsttragenden Schweisskonstruktion und es ruht mit Schraubenfedern oder Blattfedern gefedert auf Fahrschemeln 4, die hier je vier Laufräder 5 aufweisen. Die Laufräder 5 sind im Unterschied zu den bisher gebräuchlichen Wagen von grösserem Durchmesser. Zum Beispiel messen sie 450mm im Laufkranz-Durchmesser, wenigstens aber 400mm, weil das eine besseren Laufruhe gewährleistet und besonders der Verschleiss dadurch erheblich reduziert werden kann, denn die Räder 5 sind für den vorgesehenen Einsatz stark belastet, bringt es doch ein derartiges Schienenfahrzeug 1-3, das leer ca. 9 Tonnen wiegt, in beladenem Zustand auf eine Gesamtgewicht von ca. 40 Tonnen. Wegen des geringeren Verschleisses müssen denn auch die Räder 5 weniger oft gewechselt werden. Und wenn sie einmal gewechselt werden müssen, so können sie mitsamt ihrem Radlager einzeln ausgewechselt werden. Das erleichtert ein Auswechseln, das dann überall schnell vollzogen werden kann.The FIG. 1 shows two rail vehicles 1,2 of a train composition, for example, run on rails of track width 900mm as standard. The conveying direction of the concrete follows this under the train composition marked arrow. The top of the train thus forms the car 1, which enters the tunnel first, while the composition is pushed from behind, that is, from the coupled behind the car 2 cars and zuhinderst coupled locomotive. It is understood that such a composition can be composed of half a dozen or even more cars. Each individual rail vehicle 1,2 consists of a chassis 3 in the form of a self-supporting welded construction and it rests with coil springs or leaf springs sprung on subframes 4, which here have four wheels 5. The wheels 5 are in contrast to the previously used cars of larger diameter. For example, they measure 450mm in the tread diameter, but at least 400mm, because this ensures a better smoothness and especially the wear can be significantly reduced, because the wheels 5 are heavily loaded for the intended use, but it brings such a rail vehicle 1- 3, which weighs about 9 tons empty, in loaded condition to a total weight of about 40 tons. Because of the lower wear and because the wheels must be 5 less often changed. And if they ever have to be changed, they can be replaced individually with their wheel bearings. This facilitates replacement, which can then be done quickly everywhere.

Auf das Chassis 3 ist ein Behälter 8 aufgesetzt. Das Chassis weist hierzu nach oben gerichtete Steckkegel 6 auf, über welche die Stützbeine 7 des Behälters 8 von oben stülpbar sind, sodass dann der Behälter 8 auf den Chassis 3 unverrückbar und sicher aufgrund seines Eigengewichtes gehalten ist. Ein solcher Behälter 8 misst zum Beispiel etwa 8 Meter in der Länge und 1.60 Meter in der Breite und fasst ca. 12m3 Beton oder ca. 13m3 Wasser. Er ist aus Stahl gefertigt, wobei sich ein Stahl von ca. 10 bis 15mm Stärke eignet. Die Stahlplatten werden in den Radius des halbrunden Bodens 9 der Behälter 8 gebogen und an die Rundung schliessen ebene Seitenteile 10 an. An beiden Enden werden sodann die endseitigen, unten halbrunden Wände 11,12 angeschweisst. Weil der Behälter 4 mit seinen Stützbeinen 7 bloss auf das Chassis 3 gesteckt ist, lässt er sich mit einem Kran jederzeit rasch vom Chassis 3 abheben und neben dem Bahngeleise irgendwo auf einem ebenen Boden auf seine Stützbeine 7 abstellen. Das Chassis 3 mit seinen Fahrschemeln 4 und Laufrädern 5 einerseits und die Behälter 8 mit ihren Stützbeinen 7 sind also zueinanderpassende, jedoch trennbare Module und untereinander austauschbar und können unabhängig voneinander eingesetzt und zusammenkombiniert werden. Jeder Behälter 8 passt also auf jedes Chassis 3.On the chassis 3, a container 8 is placed. For this purpose, the chassis has upwardly directed plug cones 6, via which the support legs 7 of the container 8 can be pushed from above, so that then the container 8 is held immovably and securely on the chassis 3 by virtue of its own weight. Such a container 8 measures for example about 8 meters in length and 1.60 meters in width and holds about 12m 3 of concrete or about 13m 3 of water. It is made of steel, with a steel of about 10 to 15mm thickness is suitable. The steel plates are bent in the radius of the semicircular bottom 9 of the container 8 and the rounding close planar side parts 10 at. At both ends then the end, bottom half-round walls 11,12 are welded. Because the container 4 with its support legs 7 is merely stuck on the chassis 3, it can be quickly lifted off the chassis 3 with a crane at any time and park next to the rail track somewhere on a flat ground on its support legs 7. The chassis 3 with its subframes 4 and wheels 5 on the one hand and the container 8 with its support legs 7 are thus mating, but separable modules and interchangeable and can be used independently and combined together. Each container 8 thus fits on each chassis. 3

Jeder Behälter 8 weist einen trogförmig ausgebildeten Boden auf und ist oben offen. In den Stirnwänden 11,12 sind im unteren Bereich Öffnungen 13,14 vorhanden. Die vorderen Öffnungen 14 an den Wagen 1,2 sind hier mit je einem Lippenstutzen 16 ausgerüstet, während die gegenüberliegenden Öffnungen 13 mit einer Trichtermündung 15 ausgerüstet ist. Die Funktion dieses Lippenstutzens 16 und der jeweils gegenüberliegenden Trichtermündung 15 wird später noch genauer beschrieben. Im Innern jedes Behälters 8 ist ein hier nicht sichtbares Rühr- und Förderwerk angeordnet.Each container 8 has a trough-shaped bottom and is open at the top. In the end walls 11,12 openings 13,14 are available in the lower area. The front openings 14 to the car 1.2 are here each equipped with a lip nozzle 16, while the opposite openings 13 is equipped with a funnel mouth 15. The function of this lip nozzle 16 and the respective opposite mouth of the funnel 15 will be described in more detail later. In the interior of each container 8 a here not visible agitator and conveyor is arranged.

In Figur 2 sieht man einen einzelnen Wagen von schräg oben gesehen dargestellt. In dieser Ansicht sind die Stützbeine 7 am Behälter 8 besser einsehbar. Das Chassis 3 besteht im wesentlichen aus zwei parallel zueinander angeordneten Vierkant-Hohlprofilen und die Stützbeine 7 weisen unten Ausnehmungen auf, sodass sie über diese Hohlprofile stülpbar sind, und dabei mit einem horizontalen Loch über die Steckkegel 6 am Chassis 3 gestülpt werden können. Dadurch werden sie vor einem Verrutschen gesichert und brauchen aufgrund des Eigengewichtes der Behälter 8 nicht weiter mit dem Chassis 3 verbunden zu werden. Sie können deshalb auch jederzeit mit einem Kran einfach vom Chassis 3 weggehoben werden. Hierzu dienen die an den oberen Ecken des Behälters 8 angebauten Hebe-Laschen 20. Der oben offene Behälter 8 ist mittels einer Anzahl Querstreben 17, welche die beiden oberen Ränder 18 des Behälters 8 verbinden, verstärkt. An den beiden Endbereichen ist der oben offene Behälter 8 mit Stehgittern 19 abgedeckt. Die restliche obere Öffnung des Behälters ist durch ein gröberes Maschengitter abgedeckt, sodass niemand in den Behälter fallen kann. Dieses ist hier allerdings nicht eingezeichnet. Im Innern des Behälters 8 erkennt man etwas vom Rühr- und Förderwerk 21. An der Wagenvorderseite erkennt man den Lippenstutzen 16, dessen Mündungsrand aus einem elastischen, jedoch starkwandigen Hohlgummi-Ring besteht. An der hinteren Wagenseite erkennt man den Mündungstrichter 15 aus Stahl.In FIG. 2 you can see a single car seen diagonally from above. In this view, the support legs 7 on the container 8 are better visible. The chassis 3 consists essentially of two mutually parallel square hollow sections and the support legs 7 have recesses down so that they can be slipped over these hollow sections, and thereby can be slipped with a horizontal hole on the socket 6 on the chassis 3. As a result, they are secured against slipping and need not be further connected to the chassis 3 due to the weight of the container 8. They can therefore be easily lifted away from the chassis 3 at any time with a crane. The lifting lugs 20 attached to the upper corners of the container 8 serve this purpose. The container 8 which is open at the top is reinforced by means of a number of transverse struts 17, which connect the two upper edges 18 of the container 8. At the two end portions of the open-topped container 8 is covered with standing panels 19. The remaining upper opening of the container is covered by a coarser mesh so that nobody can fall into the container. This is not shown here. Inside the container 8 you can see something of the stirring and conveyor 21. At the front of the car you can see the lip nozzle 16, the mouth edge of an elastic, but strong-walled hollow rubber ring. At the rear of the car one recognizes the mouth funnel 15 made of steel.

In Figur 3 ist dieses Schienenfahrzeug nach Figur 2 zerlegt in seine wesentlichen Bauteile dargestellt. Jetzt erkennt man die Konstruktion des Chassis 3 mit seinen vier nach oben ragenden Steckkegeln 6. Die beiden parallelen Vierkant-Hohlprofile sind an ihren Endbereichen über eine je eine Brücke 22 verbunden, welche auf den Drehgestellen 23 der Fahrschemel 4 zu liegen kommen. Der Behälter 8 formt unten vier Stützbeine 7, welche mit ihren endseitigen Ausnehmungen über die Hohlprofile des Chassis 3 passen und mit ihren Löchern auf ihrer Unterseite über die Steckkegel 6 stülpbar sind, sodass der Behälter 8 sicher und passgenau mit dem Chassis 3 verbunden ist. An den beiden Endseiten des Chassis 3 sind Kupplungsteile 24,25 angebaut. Es handelt sich vorzugsweise um gebräuchliche sogenannte Willson®-Kupplungen wie sie im Tunnelbau an Schienenfahrzeugen üblich sind. Das eine Kupplungsteil, hier das Kupplungsteil 25, ist jedoch als Besonderheit ausfahrbar gestaltet, und zwar mittels einer hydraulischen Zylinder-Kolbeneinheit 26. Deren Bedeutung wird später noch klar werden. Aus dem Innern des Behälters 8 herausgezogen dargestellt erkennt man jetzt das Rühr- und Förderwerk 18. Dieses bildet eine archimedische Schraube mit einer zentralen Welle 27, die sich nach dem Einbau im Behälterinnern 8 in dessen Längsmitte erstreckt und in den beiden Stirnwänden drehbar gelagert ist. Die Stirnwände 11,12 sind hierzu mit Drehlagern 28 ausgerüstet. Von der Schraubenfläche einer eigentlichen archimedischen Schraube ist jedoch bloss noch der äussere Randbereich belassen worden, während das andere Material ausgenommen ist. Dieser etwa 10cm breite Randbereich formt ein schraubenlinienförmig verlaufendes Band 33, das von einer Anzahl radialer Streben 29 mit der zentralen Welle 27 verbunden ist, damit einerseits das Band 33 von der Welle 27 über die Streben 29 in Drehung versetzbar ist, und andrerseits der Beton im Behälter 8 bei Drehung des Rührwerkes durch die Ausnehmungen fliessen kann, gleichzeitig aber auch vom Band 33 in Längsrichtung des Wagens gefördert wird, je nach Drehsinn der Drehung. Die Welle 27 wird von einem Hydraulikmotor mit Untersetzungsgetriebe angetrieben, wobei diese Komponenten auf der Innenseite einer Stirnwand im Wendelgehäuse abgedichtet gegen Wasser und Beton eingebaut sind. Unten in der Stirnwand 11 erkennt man die Öffnung 14 in Form eines runden Loches, das etwa einen Drittel des Durchmessers des Behälters 8 misst. An der Stirnfläche 11 wie auch an der Stirnfläche 12 ist je eine Schiebervorrichtung 29 angebaut. Diese besteht aus einer Grundplatte 32, an welcher die Lippenstutzen 16 oder die Trichtermündung 15 angebaut ist, und einer hinter dieser Grundplatte 32 schwenkbar gelagerten Schieberplatte 30, sowie einer hydraulischen Zylinder-Kolbeneinheit 31, deren eines Ende schwenkbar mit der Schieberplatte 30 verbunden ist, während ihr äusseres Ende dann mit der Stirnseite des Behälters 8 nahe einer Hebe-Lasche schwenkbar verbunden ist. Mittels dieser hydraulischen Zylinder-Kolbeneinheit 31, die ebenfalls fernsteuerbar ist, lässt sich die Schieberplatte 30 gegenüber der Grundplatte 32 und der Stirnfläche 11 verschwenken, sodass sie je nach dem die Öffnung 14 in der Stirnseite 11,12 des Behälters 8 zuschliesst oder freigibt.In FIG. 3 this rail vehicle is after FIG. 2 disassembled shown in its essential components. Now you can see the construction of the chassis 3 with its four upwardly projecting stoppers 6. The two parallel square hollow sections are connected at their end via a respective bridge 22, which come to rest on the bogies 23 of the subframe 4. The container 8 shapes down four support legs 7, which fit with their end-side recesses on the hollow sections of the chassis 3 and with their holes on their underside on the plugs 6 are pushed, so that the container 8 is securely and accurately connected to the chassis 3. At the two end sides of the chassis 3 coupling parts 24,25 are attached. These are preferably conventional so-called Willson® clutches as they are common in tunneling on rail vehicles. The one coupling part, here the coupling part 25, however, is designed as a special extendable, by means of a hydraulic cylinder-piston unit 26. Their importance will be clear later. This is an Archimedean screw with a central shaft 27, which extends after installation in the container interior 8 in its longitudinal center and is rotatably mounted in the two end walls of the container 8 shown pulled out. The end walls 11,12 are equipped for this purpose with pivot bearings 28. From the screw surface of an actual Archimedean screw, however, only the outer edge region has been left while the other material is excluded. This approximately 10 cm wide edge region forms a helical belt 33 which is connected by a number of radial struts 29 with the central shaft 27, so that on the one hand the belt 33 of the shaft 27 on the struts 29 is set in rotation, and on the other hand, the concrete in the Container 8 can flow through the recesses upon rotation of the agitator, but at the same time is also supported by the belt 33 in the longitudinal direction of the carriage, depending on the direction of rotation. The shaft 27 is driven by a hydraulic motor with reduction gear, these components are sealed on the inside of an end wall in the helical housing against water and concrete. Down in the end wall 11 can be seen the opening 14 in the form of a round hole, which measures about one third of the diameter of the container 8. On the end face 11 as well as on the end face 12, a slider device 29 is ever grown. This consists of a base plate 32 to which the lip nozzle 16 or the funnel mouth 15 is attached, and a pivotally mounted behind this base plate 32 slide plate 30, and a hydraulic cylinder-piston unit 31, one end of which is pivotally connected to the slide plate 30 while its outer end is then pivotally connected to the end face of the container 8 near a lifting tab. By means of this hydraulic cylinder-piston unit 31, which is also remotely controllable, the slide plate 30 with respect to the base plate 32 and the end face 11 can pivot so that it zuschliesst depending on the opening 14 in the end face 11,12 of the container 8 or releases.

Die Figur 4 zeigt die Stirnseite eines Schienenfahrzeuges mit geöffnetem Schieber. Durch die Öffnung 14 sieht man in das Innere des Behälters 8. Man erkennt den Anfangsbereich des schraubenlinienförmigen Bandes 33 sowie eine der Radialstreben 29 des Rühr- und Förderwerkes 18. Die Grundplatte 32 der Schieberöffnungsvorrichtung ist ortsfest an der Stirnseite 11 des Behälters 8 angebaut, und zwischen dieser Gundplatte 32 und der Stirnseite 11 liegt die Schieberplatte 30, die drehbar um das Drehlager 34 gelagert ist. Die hydraulische Zylinder-Kolbeneinheit 31 verbindet die Schieberplatte 30 mit dem Behälter 8. Zieht sich diese hydraulische Zylinder-Kolbeneinheit 31 zusammen, so wird die Schieberplatte 30 in der gezeigten Darstellung im Gegenuhrzeigersinn verdreht und schwenkt daher in die Öffnung 14 hinein und verschliesst sie.The FIG. 4 shows the front of a rail vehicle with open slide. Through the opening 14 can be seen in the interior of the container 8. It can be seen the beginning of the helical band 33 and one of the radial struts 29 of the stirring and conveyor 18. The base plate 32 of the slide opening device is fixedly mounted on the end face 11 of the container 8, and between this base plate 32 and the end face 11 is the slide plate 30 which is rotatably mounted about the pivot bearing 34. The hydraulic cylinder-piston unit 31 connects the slide plate 30 with the container 8. Pulls this hydraulic cylinder-piston unit 31 together, the slide plate 30 is rotated in the illustration shown in the counterclockwise direction and therefore pivots into the opening 14 and closes it.

In Figur 5 ist der Bereich der Kupplung zweier zusammengekoppelter Schienenfahrzeuge 1,2 im Fahrzustand der Zugskomposition gezeigt. Die beiden Kupplungsteile 24,25 sind zusammengekuppelt, wobei sich das ausfahrbare Kupplungsteil 25 im ausgefahrenen Zustand befindet, in welchem eine maximale Zugkraftbelastung gewährleistet ist. In diesem Kupplungszustand kann die Zugskomposition gefahren werden. Die Schieberplatten sind geschlossen und der Beton wird im Innern der Wagen laufend umgerührt. Bedarfsweise kann auch der Drehsinn ab zu und zu gewechselt werden, damit der Beton nicht allzusehr bloss in eine Richtung hin verschoben wird. Weil die Wagen bzw. Behälter 8 oben offen sind, lassen sie sich besonders leicht befüllen. Sie können im langsamen Vorbeifahren durch eine grosse Ausschüttgosse befüllt werden, ohne dafür besonders vorbereitet zu werden. Die Ausschüttgosse wird einfach geschlossen, bis der nächstfolgende Wagen mit seinem offenen Behälter unter ihr langsam vorbeifährt.In FIG. 5 is the range of the coupling of two coupled rail vehicles 1.2 shown in the driving state of Zugskomposition. The two coupling parts 24,25 are coupled together, wherein the extendable coupling part 25 is in the extended state, in which a maximum tensile load is guaranteed. In this coupling state, the train composition can be driven. The slide plates are closed and the concrete is stirred continuously inside the car. If necessary, also the Turning to be changed from and to, so that the concrete is not too much shifted in one direction. Because the cars or containers 8 are open at the top, they are particularly easy to fill. You can be filled while driving slowly through a large Ausschüttgosse, without being specially prepared for it. The discharge gutter is simply closed until the next following car with its open container passes underneath it slowly.

Wenn der Zug am seinem Bestimmungsort vor der Tunnelbrust angekommen ist, werden die Wagen eng zusammengekuppelt, indem die hydraulischen Zylinder-Kolbeneinheiten an den Kupplungsteilen 24,25 betätigt werden. Es stellt sich dann die Situation wie Figur 6 gezeigt ein. Dadurch wird der Lippenstutzen 16 der Öffnung 14 in der jeweiligen Stirnseite 11 unter Zusammenquetschens und somit dichtem Anliegen seiner Hohlgummi-Lippe in die Trichtermündung 15 der gegenüberliegenden Öffnung 13 gepresst, wodurch eine dichte Verbindung der beiden Behälter 8 erzeugt wird. Dieses Zusammenpressen der Behälter ist selbst in den engsten Kurvenradien möglich, welche im Tunnelbau vorkommen. Die Trichtermündung und der zugehörige Lippenstutzen sind extra so konstruiert, das ein Zusammenpressen unter einem Winkel von bis zu einigen Grad von der elastischen Hohlgummi-Lippe ausgeglichen wird. Jetzt können die Schieberplatten an den beiden Stirnseiten aufgeschwenkt werde, was wieder hydraulisch mittels der Zylinder-Kolbeneinheiten 31 geschieht. Damit ist ein offener Durchgang von Behälter zu Behälter geschaffen, wobei sich die Öffnungen in den Stirnseiten ja bis hinunter auf den Boden der Behälter erstrecken. Wenn jetzt die Rührwerke in Drehung versetzt werden, so wirken sie als Förderwerke und fördern den Beton von Wagen zu Wagen, bis er schliesslich durch die vordere Öffnung 14 des vordersten Wagens auf das Förderband eines Förderbandwagen fällt, der ihn schliesslich in einen Beschicktrichter einer Betonpumpe transportiert.When the train has arrived at its destination in front of the tunnel breast, the carriages are tightly coupled together by actuating the hydraulic cylinder-piston units on the coupling parts 24,25. It then turns the situation like FIG. 6 shown. Thereby, the lip nozzle 16 of the opening 14 in the respective end face 11 is pressed together crushing and thus dense concern of its hollow rubber lip in the funnel mouth 15 of the opposite opening 13, whereby a tight connection of the two containers 8 is generated. This compression of the container is possible even in the tightest curve radii, which occur in tunneling. The mouth of the funnel and its associated lip are specially designed to compensate for compression at an angle of up to a few degrees from the elastic hollow lip. Now the slide plates can be swung open at the two end faces, which again happens hydraulically by means of the cylinder-piston units 31. Thus, an open passage is created from container to container, with the openings in the end faces yes down to the bottom of the container. Now, when the agitators are rotated, they function as conveyors and convey the concrete from trolley to trolley until finally it falls through the front opening 14 of the foremost trolley onto the conveyor belt of a conveyor belt trolley, which finally transports it into a feed hopper of a concrete pump ,

Anstatt ein Rühr- und Förderwerk wie das oben beschrieben kann auch eine alternative Ausführung dienen. An der Welle 27 ragen in radialer Richtung Rührarme von dieser ab. Am äusseren Ende tragen diese Rührarme je ein Paddel, das schiefwinklig zur Wellenachse mittels einer Schraubverbindung mit dem Rührarm verbunden ist. Die Antriebswelle 27 dieses Rühr- und Förderwerkes 18 wird von einem Elektromotor mit Untersetzungsgetriebe angetrieben und ist ebenfalls fernsteuerbar. Beim Drehen wirken die Paddel ähnlich wie Schneepflüge und nebst dem Umrühren des im Behälter befindlichen Betons wird dieser auch noch gegen gefördert.Instead of a stirring and conveying device as described above can also serve an alternative embodiment. On the shaft 27 protrude in the radial direction of this stirring arms. At the outer end, these stirring arms each carry a paddle which is inclined at an angle to the shaft axis by means of a screw connection the mixing arm is connected. The drive shaft 27 of this agitator and conveyor 18 is driven by an electric motor with reduction gear and is also remotely controllable. When turning the paddles act similar to snowploughs and in addition to the stirring of the concrete contained in the container this is also promoted against.

Anstelle der Austragung des Betons am vordersten Wagen auf das Förderband kann dies alternativ einen speziellen Betonpumpe-Wagen mit Direktförderung in die Betonpumpe erfolgen. Ein solcher Betonpumpe-Wagen 35 ist in Figur 7 dargestellt. Vorne im Wagen ist die Betonpumpe untergebracht und hinten die Direktfördereinheit 36, die aus einem Betonbehälter, das heisst einer Mulde mit Rührwerk besteht. Dieser Wagen und seine Direktfördereinheit sind direkt mit dem vordersten Schienenfahrzeug 1 mit Behälter 8 koppelbar. Hierzu weist die Durchfördereinrichtung 36 einen Stahlkonus mit aufvulkanisierter Dichtung und einen Stahltrichter als Koppelelement auf. Dadurch kann ein dichter Übergang vom vordersten Wagen 1 zur Direktfördereinheit 36 geschaffen werden. Der Stahlkonus mit Dichtung, sowie der Stahltrichter sind an die Mulde angeschraubt und können somit einfach ausgewechselt werden. Das Zusammenziehen der beiden Wagen 1 und 35 wird mit einer hydraulischen Zugeinrichtung bei der Kupplung bewerkstelligt. Die Verschiebemechanik besteht aus einer Stahlrahmen-Konstruktion, die mittels eines Kopplungszylinders eingefahren werden kann. Zur Verriegelung der Kupplung in ausgefahrenem Zustand sind seitlich zwei federbelastete hydraulische Verriegelungszylinder angebracht. Die Verriegelungszylinder und der Kopplungszylinder sind hydraulisch in Serie geschaltet so dass bei Betätigung des Steuerventils zuerst nacheinander die beiden Verriegelungszylinder ausgefahren werden und erst dann der Kopplungszylinder eingezogen wird.Instead of discharging the concrete on the foremost trolley onto the conveyor belt, this can alternatively be done with a special concrete pump trolley with direct delivery into the concrete pump. Such a concrete pump cart 35 is in FIG. 7 shown. The concrete pump is located in the front of the wagon and the direct feed unit 36, which consists of a concrete container, that is to say a trough with agitator, is located at the back. This car and its direct feed unit can be coupled directly to the foremost rail vehicle 1 with container 8. For this purpose, the feed-through device 36 has a steel cone with a vulcanized seal and a steel funnel as a coupling element. As a result, a tight transition from the foremost carriage 1 to the direct feed unit 36 can be created. The steel cone with seal, as well as the steel funnel are screwed to the trough and can therefore be easily replaced. The contraction of the two cars 1 and 35 is accomplished with a hydraulic pulling device in the coupling. The sliding mechanism consists of a steel frame construction, which can be retracted by means of a coupling cylinder. To lock the coupling in the extended state, two spring-loaded hydraulic locking cylinders are attached laterally. The locking cylinder and the coupling cylinder are hydraulically connected in series so that when the control valve is actuated, first the two locking cylinders are extended one after the other and only then the coupling cylinder is retracted.

Die Mulde besteht aus einer selbsttragenden Konstruktion aus gekanteten und geschweissten Blechen. Sie ist oben offen und mit einem demontierbaren Gitter mit integriertem hydraulischen Rüttler abgedeckt. Die Mulde wird auf das Wagenchassis mit vier Füssen aufgeschraubt. An der hinteren Stirnseite der Mulde ist bei der Einlassöffnung ein hydraulisch betriebener Plattenschieber installiert, wie jene an den anderen Wagen. Die Auslassöffnung befindet sich unten an der Mulde und führt direkt in den darunter liegenden Ansaugraum der Betonpumpe. Das Rührwerk besteht aus einer Zentralwelle mit aufgeschweissten Wendelsegmenten. Bei Verschleiss können diese Wendelsegmente ausgetauscht werden. Der Antrieb des Rührwerkes erfolgt hydraulisch. Das Rührwerk ist so konstruiert, dass der Spritzbeton beim Rühren gleichzeitig in Richtung Austragsöffnung gefördert wird. Nach der Entleerung der Behälter 8 des Betonzuges und des Betonbehälters auf dem Betonpumpe-Wagen 35 wird die Hydraulik freigeschaltet und der Kopplungszylinder durch die Zugkraft der Lokomotive wieder ausgezogen. In ausgefahrenem Zustand der Kupplung werden die Verriegelungszylinder durch die Federkraft eingefahren und die Verschiebemechanik dadurch blockiert. Das korrekte Verriegeln wird dadurch angezeigt, dass rot markierte Indikatorbolzen an den Verriegelungszylindern im Zylinderkolben verschwinden. Das Wagenchassis besteht aus einer stabilen Stahlkonstruktion, welche die Verbindung der beiden Drehgestelle bildet. Das Wagenchassis dient als Auflager der Mulde und der Betonpumpe und nimmt im Fahrbetrieb die Längskräfte über die Wagenkupplungen auf.The trough consists of a self-supporting construction of canted and welded sheets. It is open at the top and covered with a removable grid with integrated hydraulic vibrator. The trough is screwed onto the carriage chassis with four feet. At the rear end of the trough is at the inlet opening a hydraulically operated gate valve installed, like those on the other cars. The outlet opening is located at the bottom of the trough and leads directly into the suction chamber underneath the concrete pump. The agitator consists of a central shaft with welded spiral segments. When worn, these spiral segments can be replaced. The drive of the agitator is hydraulic. The agitator is designed in such a way that the shotcrete is simultaneously conveyed towards the discharge opening during stirring. After emptying the container 8 of the concrete train and the concrete container on the concrete pump carriage 35, the hydraulic system is released and the coupling cylinder pulled out by the traction of the locomotive again. In the extended state of the clutch, the locking cylinders are retracted by the spring force and thereby blocks the displacement mechanism. The correct locking is indicated by the fact that indicator bolts marked red disappear on the locking cylinders in the cylinder piston. The car chassis consists of a sturdy steel construction, which forms the connection of the two bogies. The car chassis serves as a support for the trough and the concrete pump and absorbs the longitudinal forces on the car couplings while driving.

Die Drehgestelle sämtlicher Wagen der Komposition bestehen aus einer stabilen Stahlkonstruktion. Die Lagerung der Drehgestelle erfolgt über eine Zentralkugelpfanne. Die Radsätze sind mit einer Federung ausgestattet. Bei den Wagenkupplungen handelt es sich um sogenannte Willison®-Kupplungen, wie sie im Tunnelbau an Schienen-fahrzeugen üblich sind. Das eine Kupplungsteil ist jedoch als Besonderheit ausfahrbar gestaltet, und zwar mittels eines hydraulischen Kopplungszylinders. Die maximale Zugkraftbelastung ist dann gewährleistet, wenn sich das ausfahrbare Kupplungsteil im ausgefahrenen Zustand befindet. Nur in diesem Kupplungszustand darf die Zugs-komposition gefahren werden.The bogies of all cars of the composition consist of a stable steel construction. The bogies are stored via a central ball socket. The wheelsets are equipped with a suspension. When the car couplings are so-called Willison® couplings, as they are common in tunneling on rail vehicles. However, the one coupling part is designed as a special extendable, by means of a hydraulic coupling cylinder. The maximum tensile load is guaranteed when the extendable coupling part is in the extended state. Only in this coupling condition may the train composition be driven.

Mit der Direktfördereinheit kann der Beton aus den Behälter 8 des Zuges in einem geschlossenen System ohne Materialverluste direkt zu der Betonpumpe gefördert werden. Zusätzlich kann der Betonbehälter der Direktfördereinheit 36 mit der Schmiermischung für den ersten Betoniervorgang gefüllt werden. Diese Zugskomposition wird zusammen mit der Direkt-fördereinheit an die Betonierstelle herangefahren. Wenn der Zug stillsteht, wird die Stromversorgung über ein Kabel von der Pumpenstation aus über den Elektromotor auf dem Energieversorgungswagen erstellt und der Dieselmotor ausgeschaltet. Anschliessend werden die einzelnen Wagen 1,2 und auch der Betonpumpe-Wagen 35 mit seiner Direktfördereinheit 36 mit dem vordersten Wagen 1 zusammengezogen, indem über ein Steuerventil die hydraulischen Zylinder an den Kupplungen betätigt wird. Dadurch wird der Auslasskonus des vordersten Wagens 1 in den Einlasskonus der Direktfördereinheit 36 geschoben und durch die Gummidichtung eine dichte Verbindung zwischen den beiden Mulden erzeugt. Jetzt können die Schieberplatten an den Stirnseiten beider Mulden aufgeschwenkt werden, was wiederum hydraulisch über ein Steuerventil mittels der Schieberzylinder geschieht. Damit ist ein offener Durchgang von Mulde zu Mulde geschaffen. Durch Umschalten der Drehrichtung der Rührwerke wirken diese als Förderschnecke und fördern den Beton von Mulde zu Mulde, bis er schliesslich durch die vordere Öffnung des Behälters 8 des vordersten Wagens 1 in den Betonbehälter der Durchfördereinheit 36 ausfliesst. Die Durchsatzmenge wird am vordersten Wagen 1 über den Öffnungsgrad des Schiebers händisch durch den Betonpumpenmaschinisten geregelt.With the direct feed unit, the concrete can be conveyed from the container 8 of the train in a closed system without loss of material directly to the concrete pump. In addition, the concrete container of the direct feed unit 36 can be filled with the lubricant mixture for the first concreting operation. These Train composition is moved up to the concreting station together with the direct conveyor unit. When the train stops, the power is supplied via a cable from the pump station via the electric motor on the power supply truck and the diesel engine is switched off. Subsequently, the individual car 1.2 and also the concrete pump carriage 35 are contracted with its direct feed unit 36 with the foremost car 1 by the hydraulic cylinder is actuated at the clutches via a control valve. As a result, the outlet cone of the foremost carriage 1 is pushed into the inlet cone of the direct feed unit 36 and a tight connection between the two troughs is created by the rubber seal. Now the slide plates can be pivoted on the front sides of both wells, which in turn is done hydraulically via a control valve by means of the slide cylinder. This creates an open passage from trough to trough. By switching the direction of rotation of the agitators they act as a screw conveyor and convey the concrete from trough to trough until it finally flows through the front opening of the container 8 of the foremost carriage 1 in the concrete container of the feed unit 36. The flow rate is manually controlled by the concrete pump operator at the foremost carriage 1 via the opening degree of the slider.

Nach dem Entleeren der Wagen müssen die Schieberplatten an den Stirnseiten beider Mulden geschlossen werden und die RoCon-Shuttles und die Direktfördereinheit mit Hilfe der Lokomotive wieder auseinander gezogen werden. Direkt bei der Betonierstelle wird eine Grobreinigung der Mulden mittels Spritzwasser aus einem Wasserschlauch vorgenommen. Dabei wird die Eintrittsöffnungen der Mulde geschlossen und der Behälter soweit nötig mit Wasser gefüllt. Das Schmutzwasser bleibt während der Rückfahrt in der Mulde und wird bei der Waschanlage in der MFS entsorgt. Vor der Rückfahrt muss kontrolliert werden, ob beide Verriegelungszylinder korrekt eingerastet haben, sodass der rote Indi-katorbolzen am Zylinderboden nicht mehr sichtbar ist. Während der Rückfahrt wird das Rührwerk eingeschaltet, um eine Entmischung respektive Aushärtung des Restbetons zu verhindern. Der Abbindeprozess respektive die Abbindezeit in den Mulden bei der Rückfahrt ist abhängig von der Betonrezeptur und wird auch an die zu bewältigende Fahrstrecke angepasst. Die Entleerung des Schmutzwassers und des Restbetons sowie die Endreinigung erfolgt in der MFS. Vor dem Wiederbelad sind die Mulden und die Auslaufkonuse zu reinigen. Für Revisionszwecke kann ein leerer Behälter 8 vom Wagenchassis abgehoben werden. Dazu müssen die Befestigungsschrauben an den vier Füssen des Behälters 8 gelöst werden. Anschliessend kann der Behälter 8 mit einem Kran mit ausreichender Tragkraft an den vier Schäkeln 20 (Hebe-Laschen), welche an jeder Ecke des Behälters 8 angebracht sind, angehoben werden.After emptying the carriages, the slide plates at the ends of both troughs must be closed and the RoCon shuttles and the direct conveyor unit must be pulled apart again with the aid of the locomotive. Directly at the concreting place a rough cleaning of the hollows is done by means of splash water from a water hose. In this case, the inlet openings of the trough is closed and the container as necessary filled with water. The dirty water remains in the trough during the return journey and is disposed of in the washing plant at the MFS. Before returning, check whether both locking cylinders have engaged correctly, so that the red indicator pin on the cylinder bottom is no longer visible. During the return journey, the agitator is switched on to prevent segregation or hardening of the residual concrete. The setting process or the setting time in the hollows on the return trip depends on the Concrete recipe and is also adapted to the route to be handled. The emptying of the dirty water and the residual concrete as well as the final cleaning takes place in the MFS. Before reloading, the troughs and the discharge cone must be cleaned. For inspection, an empty container 8 can be lifted from the car chassis. For this purpose, the fastening screws must be solved at the four feet of the container 8. Subsequently, the container 8 can be lifted by a crane with sufficient carrying capacity on the four shackles 20 (lifting tabs) which are attached to each corner of the container 8.

Zum Reinigen nach dem Entleeren werden die einzelnen Behälter 8 der Wagen einfach von oben mit Wasser ausgespritzt, was bei drehendem Rührwerk 18 erfolgen kann, sodass auch dieses von allen Seiten abgespritzt werden kann. Weil die Behälter 8 ja von oben zugänglich sind, können die Innenwände der Behälter 8 leicht mittels eines Schlauches mit Druckwasser abgespritzt werden. Das nachher im Behälter 8 vorhandene Wasser wird mit dem Rührwerk 18 stets in Bewegung gehalten, sodass sich keine Betonreste an der Behälterwand anbacken können. Bevor der Zug wieder aus dem Tunnel herausgefahren wird, werden die Kupplungen zunächst wieder wieder ausgefahren. Wenn der Zug wieder aus dem Tunnel herauskommt, wird das Schmutzwasser fachgerecht entsorgt, indem es in eine dafür vorgesehene Wanne abgelassen wird.For cleaning after emptying the individual containers 8 of the car are simply sprayed from above with water, which can be done with rotating agitator 18, so that this can be hosed from all sides. Because the container 8 are indeed accessible from above, the inner walls of the container 8 can be easily hosed by means of a hose with pressurized water. The water subsequently present in the container 8 is always kept in motion with the agitator 18, so that no concrete residues can caking on the container wall. Before the train is pulled out of the tunnel again, the clutches are first extended again. When the train comes out of the tunnel, the waste water is disposed of properly by draining it into a dedicated tub.

Die Vorteile dieses Betontransportsystems sind vielfältig. Zunächst einmal liegt der grösste Vorteil gegenüber den herkömmlichen Trommelwagen darin, dass das Beladen des Zuges sehr viel einfacher und rascher vonstatten geht. Mit den einzelnen Schienenfahrzeugen mit je oben offenem trogförmigen Behälter 8 kann einfach unter dem Betonsilo in langsamer Fahrt vorbeigefahren werden und während der Fahrt werden die einzelnen Behälter 8 befüllt. Die Ladegeschwindigkeit wird nicht mehr durch die Zugskomposition in irgendeiner Weise beschränkt, sondern einzig durch die Ausschüttkapazität am Betonsilo. Einzig zwischen den Wagen muss die Ausschüttgosse kurz geschlossen werden, bis der nächste Wagen unter ihr angekommen ist. Dann wird wieder geöffnet und der Wagen wird in Fahrt schön gleichmässig über seine ganze Länge befüllt. Der Zug braucht nach dem Beladen nicht mehr rückwärts rangiert zu werden, sondern kann direkt in den Tunnel einfahren. Es sind weder vor noch nach dem Beladen irgendwelche Arbeiten nötig, wie das bisher vor dem Beladen zum Entfernen der Luckendeckel und nach dem Beladen für das Verschliessen der Lucken nötig ist und was ein zeitraubendes Prozedere ist.The advantages of this concrete transport system are manifold. First of all, the biggest advantage over conventional drum cars is that loading the train is much easier and quicker. With the individual rail vehicles with each open-topped trough-shaped container 8 can be easily passed under the concrete silo in slow speed and while driving the individual containers 8 are filled. The loading speed is no longer limited by the train composition in any way, but solely by the discharge capacity on the concrete silo. Only between the car, the discharge gutter must be closed briefly until the next car has arrived under her. Then it is opened again and the car is filled nicely evenly over its entire length. The train does not need to be rearranged after loading, but instead can enter directly into the tunnel. No work is required either before or after loading, as was previously required before loading to remove the gap covers and after loading to close the gaps and is a time-consuming procedure.

Das Entladen erfolgt viel transparenter, indem man jederzeit den Überblick über den Füllstand der Behälter 8 hat, weil diese oben offen sind und sich auch vollständig entleeren. Auch die Reinigungs- und Unterhaltsarbeiten gestalten sich viel einfacher und sie sind entsprechend rascher zu bewältigen. Vorallem weil die Behälter 8 oben offen sind, lassen sie sich sehr viel leichter und gezielt mit einem Druckwasserstrahl abreinigen, während bei den Trommelwagen nach dem Entladen bloss von den endseitigen Mündungen her Wasser hineingespritzt werden konnte. Bei den hier vorgestellten Schienenfahrzeugen hingegen kann ein Mann, der oberhalb der Wagen auf einem dort angeordneten Laufsteg und Stehgitter 19 positioniert ist, die leeren Wagen bzw. deren Behälter bei ihrer langsamen Vorbeifahrt gezielt abspritzen, während deren Rührwerke 18 in Betrieb sind. Das Wasser in den so mit Wasser angefüllten Behältern 8 wird durch das Rührwerk 18 stets umgewälzt, sodass sich bis zum Entwässern ein homogenes Schmutzwassergemisch gebildet hat, und sich keine Betonreste am Boden oder an den Seitenwänden der Behälter 8 ansetzen.The unloading is much more transparent, by always having an overview of the level of the container 8, because they are open at the top and also empty completely. The cleaning and maintenance work is much easier and they are correspondingly faster to deal with. Especially because the containers 8 are open at the top, they can be much easier and targeted clean with a pressurized water jet, while in the drum car after unloading could only be injected from the end-side mouths ago water. In contrast, in the rail vehicles presented here, a man who is positioned above the car on a catwalk and standing grid 19 arranged there, the empty carts or their container in their slow pass by selectively spray while their agitators 18 are in operation. The water in the water-filled containers 8 is always circulated by the agitator 18, so that has formed a homogeneous wastewater mixture until dewatering, and no concrete residues on the bottom or on the side walls of the container 8 set.

Weitere Vorteile entstehen durch den Einsatz des Betontransportwagens mit Direktförderung in Betonpumpe. So kann die Schmiermischung (ca. 0.5m3 bis 1m3) bereits beim Verlad der ersten Garnitur RoCon-Shuttle mit in den Tunnel gefahren werden (unabhängig zu RoCon-Shuttle). Durch die saubere Zufuhr des Betons zur Pumpe wird eine Verschmutzung der Sohle vermieden, was bisher infolge Verlusts von Beton auf dem Förderband in Kauf genommen werden musste. Das System bietet infolge seiner Einfachheit wegen des Wegfalls der Förderbandkomponenten (Abstreifer, Rollen etc.) eine hohe Verfügbarkeit und ist wartungsarm und die Mulde des Direktfördereinzeit wirkt als Buffer. Es kann ohne weiteres SCC-Beton (self compacting concrete) verarbeitet werden. Auch das Ausstossen von Restbeton in Leitungen von der Schalung in den Behälter der Direktfördereinheit ist ohne weitere möglich, wodurch Verschmutzungen der Baustelle vermieden werden.Further advantages result from the use of the concrete transport wagon with direct transport in concrete pump. So the lubrication mixture (about 0.5m 3 to 1m 3 ) can already be driven into the tunnel when loading the first set RoCon-Shuttle (independent to RoCon-Shuttle). The clean supply of the concrete to the pump prevents contamination of the sole, which previously had to be accepted as a result of the loss of concrete on the conveyor belt. The system offers high availability due to its simplicity due to the elimination of the conveyor belt components (scrapers, rollers, etc.) and is low maintenance and the trough of the direct conveying time acts as a buffer. It can be processed without further SCC (self-compacting concrete). The ejection of residual concrete in lines of the formwork in the container of the direct feed unit is possible without further, causing contamination of the Construction site to be avoided.

Insgesamt ist mit dieser Vorrichtung bzw. mit diesem Betontransportsystem eine stark erhöhte Kapazität zu erreichen, weil Standzeiten der Zugskomposition vermieden werden können. Im Prinzip kann diese bis auf das eigentliche Entladen an der Tunnelbrust sowie den Richtungswechsel vor dem Tunnel ständig in Fahrt sein, jedenfalls sowohl für das Befüllen wie auch für das Abreinigen nach dem Beladen. Für diese Zwecke wird die Fahrt bloss verlangsamt, jedoch muss der Zug weder für das Beladen noch für das Reinigen der Behälter still stehen.Overall, with this device or with this concrete transport system to achieve a greatly increased capacity, because service life of the train composition can be avoided. In principle, this can be up to the actual unloading at the tunnel breast and the direction change in front of the tunnel constantly in motion, at least both for filling as well as for cleaning after loading. For these purposes, the drive is slowed down, but the train does not have to stand still for loading or cleaning the containers.
