Definitions

  • 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.
  • 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 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.
  • 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 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.
  • 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.
  • 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.
  • the concrete is protected against segregation during transport on the rails in the open, trough-shaped containers by stirring with a stirrer.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a container 8 is placed on the chassis 3, a container 8 is placed.
  • 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.
  • 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.
  • 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
  • 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.
  • FIG. 2 you can see a single car seen diagonally from above.
  • 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.
  • 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.
