Definitions

  • This invention relates to a method for concrete transport on rails, as well as a device 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.
  • 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.
  • Conventional transport trains therefore consist of railway cars, on each of which a cigar-shaped drum is installed lying, 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.
  • 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.
  • 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 has to drive backwards from the concrete silo after filling, past the lid machine where this happens on the occasion of a temporary, locally defined stopover.
  • the actual filling of a drum is done by passing through the train under a concrete silo and when each of the opening of a drum comes to rest under the discharge gutter 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.
  • the filled train then drove pushed by a locomotive into the tunnel, under constant rotation of Tommein on the individual cars. 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.
  • 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. In front of tunnel portals, however, there is little space available in most cases.
  • 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.
  • 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 can be transported to a tunnel breast.
  • This object is achieved by a method for concrete transport 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 afterwards seemed transported, the concrete in the open, trough-shaped containers are protected against segregation by stirring with an agitator, and for discharging the containers of the following rail vehicles are sealed together by contraction of the couplings, and that afterwards concrete is conveyed by the stirring and conveyor of a container in the next container and finally funded from the front wall opening of the foremost rail vehicle on a conveyor belt carriage and then into the feed hopper of a concrete pump ,
  • the object is further achieved by a device for concrete transport on rails, consisting of rail vehicles, each with an open-topped trough-shaped container with slide or flap opening in the end-side end walls, wherein in the open trough-shaped container, a stirring and conveyor is arranged, by means of which the in-situ concrete mixable and from the slide or flap opening in the end wall of the container can be conveyed.

Abstract

Le procédé est mis en oeuvre au moyen de wagons (1, 2) présentant chacun un conteneur en forme d'auge (8), ouvert vers le haut. Les conteneurs (8) peuvent être remplis au fur et à mesure que le convoi s'achemine lentement, permettant ainsi le transport du béton. Un système d'agitation (18) est prévu dans les conteneurs en forme d'auge (8) en vue d'empêcher toute séparation du béton durant le transport. Pour le déchargement du béton, les wagons sont tirés, via leurs accouplements (24, 25), de manière à constituer une liaison étanche des conteneurs individuels. Les ouvertures coulissantes dans les parois terminales (11, 12) des conteneurs (8) sont alors ouvertes et le système convoyeur (18) achemine le béton d'un conteneur (8) à l'autre (8) vers l'avant du train, où le béton est déchargé par l'ouverture de paroi avant du conteneur (8) du wagon situé le plus en avant (1), via une bande transporteuse, dans la trémie d'une pompe à béton ou dans des wagons de transport du béton qui acheminent le béton directement dans une pompe à béton.
