Definitions

  • the invention relates to a method and a device for the production of concrete in a tunnel that can be driven on by rail vehicles, in which aggregates and cement are removed from vehicle chambers and mixed with the addition of a certain amount of mixing water, and the mixed batch is transported to a higher level for delivery.
  • the rail vehicle has a cement silo with two chambers and two silos for aggregates behind it. Outside the tunnel, the quantity is metered into the individual silos. Two batches of concrete can be produced one after the other at the work site.
  • a cement silo chamber and an aggregate silo are emptied simultaneously on a common conveyor belt, which transfers the premixing to an elevated conveyor, which in turn empties into a mixer trough into which a certain amount of mixing water is also added.
  • a disadvantage of this method is that the batches must be metered outside the tunnel so that the mixing ratio in the tunnel can no longer be changed, and the need to work with large batches, because otherwise the maneuvering of the vehicles would be too time-consuming.
  • Large mixer batches do not allow fine adjustment to the current demand and are also disruptive in the event of breakdowns, with the need to have to be transported back in special vehicles.
  • the common trans port of cement and aggregates through the Hoch- resp. Steep conveyor leads to loss of cement, as trickling down of cement is unavoidable and furthermore to excessive cement dust formation. In addition, the workload for cleaning below the conveyor to the mixer is considerable.
  • the US-A-1,075,350 shows a method in which the additives and binders are stored undosed in successive storage containers of a movable train and are temporarily stored in bunkers by means of lateral conveyor belts and subsequent elevators, from which they reach the mixer via quantity dosing devices, which is continuous can be operated.
  • this method allows the concrete mix to be changed quickly at the construction site according to the recipe, the method cannot be used for use in narrow tunnels due to the lateral conveyor belts and the considerable height.
  • the quantity dispensers do not work precisely enough for the production of quality concrete.
  • the object of the invention is to provide a method and an extremely space-saving device for carrying it out, both with dry cement-aggregate premixes and from separate mixing components in a very short time on site in terms of quantity and recipe, small batches of high-quality concrete that can be dusted with cement dust -to be able to produce without loss.
  • the recipe can vary from batch to batch can be changed on site, for example, by adding pore fillers to achieve waterproof concrete.
  • the supply train can contain dry premixes from aggregates and binders, which are weighed directly into the mixer bypassing separate dosing devices, it is preferred to use only simple filling stations for aggregates and cement outside the tunnel.
  • the mixing components are then metered into the mixer one after the other by additive weighing and mixed while the mixer is ramping up.
  • the feeding of the mixing components including water and their additive weighing in the mixer housing takes approx. 45 seconds for 1 m3 of concrete.
  • the mixing time while the mixer starts up is about 40 seconds. Taking into account the emptying and return times of the mixer, a concrete batch of 1 m3 takes approx. 2 minutes, which corresponds to an output of 30 m3 / h.
  • the device for the production of concrete, in particular in a tunnel that can be driven by rail vehicles, is characterized by the features of claim 5.
  • the cement can get from the storage container through a closed tube directly into the housing of the mixer.
  • This single transfer station can be made dust-free.
  • a single housing thus serves as a weighing container, mixing container and elevator, which creates a device with an extremely small footprint.
  • the feature of claim 2 also contributes to this.
  • the feature according to claim 6 allows various binders to be conveyed dust-free into the mixer housing and additively weighed there.
  • each chassis for the storage container has an integrated endless conveyor belt, that extends directly under the storage container, so that the overall height is slightly increased at most without overhanging. This is important for use in a narrow tunnel.
  • a number of chassis 12 are coupled together to form a train on a rail track 10.
  • a storage container 14 for binding agents On the frontmost chassis 12 of the train there is a storage container 14 for binding agents.
  • Storage containers 16 for additives are arranged on the chassis 12 behind them.
  • In the chassis 12 are located under the bottoms of the storage containers 14, 16, conveyor belts 18, which project forward and backward over the storage containers 14, 16 and are designed to rise slightly upwards, such that the front end of a conveyor belt 18 is the rear end of the conveyor belt 18 of a chassis 12 in front overlaps.
  • Each aggregate container 16 has constantly open floor outlets 20 above the conveyor belt 18. Only when the conveyor belt 18 is running, discharge takes place. First, only the first conveyor belt 18 runs and empties the container 16 above it. Then the second conveyor belt 18 is switched on as the first conveyor belt continues and empties it under the container 16 in front of it to the front end of the train, etc. The conveyor belts thus take over in addition to the transport still the discharge control.
  • the storage container 14 is divided by a longitudinal wall 22 into two chambers 24, 26.
  • the larger chamber 24 is used to hold cement, the smaller chamber 26 to hold an auxiliary binding agent, for example rock powder.
  • Each of the chambers 24, 26 ends at the bottom in a trough-shaped bottom in which a screw conveyor 28 or 30 is arranged.
  • the bottom of the container 14 runs at the same distance from the conveyor belt 18 running underneath it, so that the additives are conveyed below the bottom of the container 14.
  • the two screw conveyors 28, 30 protrude beyond the reservoir 14 and are each driven by a motor 32.
  • chassis 12 In front of the train having the chassis 23 there is another chassis 12 which carries a multiple conveyor device 34 which has a steeply rising conveyor belt 36 which is similar in cross section to the conveyor belts 18 and two conveyor screws 38, 40 arranged above it and lying next to one another, which have approximately the same inclination like the conveyor belt 36.
  • the outlets of the screw conveyors 28, 30 are each connected to the inlets of the screw conveyors 38, 40 in a dust-tight manner by means of transition couplings 42.
  • the aggregate conveyor belt 18 below the binder container 14 unloads directly onto the conveyor belt 36.
  • the chassis 12 of the multiple conveying device 34 carries a water reservoir 44 which is connected to the water supply network via a long supply hose 46.
  • a pump 48 delivers mixing water from this storage container 44 via a hose 50 with a cross section which is considerably larger than that of hose 46.
  • a mixer 52 is arranged on its own chassis 12, which has a cylindrical housing 54 which carries on both sides two rollers 56, 58 which run on an angled rail track 60 to move the housing 54 from a low position (loading position ), in which the housing 54 points obliquely upwards with its cylinder axis, into which in FIG. 1 dash-dotted, forward offset loading and unloading position 54 ⁇ in which the cylinder axis is arranged approximately horizontally or slightly inclined downwards to the front.
  • Rail 60 is divided at 62 (FIG. 8).
  • the upper Part of the rail track 60 is fixedly mounted on the chassis 12, while the lower rail piece 64 is supported on a weighing frame 66, which is mounted on the chassis 12 via two laterally opposite front load cells 68 and a central rear load cell 70.
  • a transport lock 72 fixes the weighing frame 66 to the chassis 12 during transport.
  • the mixer 52 rests on stops 74 which are attached to the lower ends of the rail pieces 64.
  • the housing 54 has an upper inlet opening 76 and a front end emptying opening 78.
  • the drive motor 80 with a gear for driving the mixer shaft, not shown, is also located adjacent to the front end side of the housing 54.
  • the conveyor belt 36 and the two screw conveyors 38, 40 and the mixing water hose 50 end at the top in a funnel 82 to which a dust filter 83 is connected in a dust-tight manner at the top.
  • Overlapping flexible lamellae hang down from a bottom opening of the funnel 82 and form a circumferentially closed apron 85 which fits tightly against the edge of the inlet opening 76 of the housing 54 of the mixer 52 when it is in the down position.
  • the mixing components are passed from the hopper 82 into the mixer 52 through the inlet opening 76 immediately below, without generating dust.
  • a drive device 84 for the mixer 52 is shown in FIGS. 11 and 12. This has a pair of rigidly interconnected rockers 86, which are fastened to a transverse shaft 88 arranged adjacent to the front axle of the chassis 12 behind it and which, when the mixer 52 is in the low position, extend rearward to the housing 54 at an angle of approximately 30 ° . On this are the bottom surface line of the Ge housing 54 about tangent plane rotatable coaxial driving rollers 90 which engage in open slots 92 of the rocker 86 at the ends. The width of the slots 92 is greater than the diameter of the driving roller 90.
  • a pivot lever 94 is fastened in the center to the transverse shaft 88, at the end of which a double-acting pressure medium cylinder 96 is articulated.
  • the plane containing the transverse shaft 88 and this articulation point increases in the low position of the mixer 52 and rises to the rear at an angle of approximately 60 °.
  • the rear end of the pressure cylinder 96 is articulated on the vehicle frame 12.
  • the rockers 86 are pivoted clockwise (FIG. 11).
  • the mixer 52 is moved obliquely upwards along the rising branch of the rail track 60.
  • the entrainment rollers 90 move downwards in the slots 92.
  • the housing 54 of the elevator mixer 52 pivots and reaches the unloading position 54 ⁇ .
  • the rockers 86 have been pivoted about 90 °. In the unloading position, the longitudinal axis of the cylindrical housing 54 is inclined slightly downwards.
  • the front end emptying opening 78 is opened and the concrete is emptied into a feed hopper underneath it of a concrete pump or a spraying system.
  • FIGS. 5, 5a and 6 illustrate a modification in that the train feeding the storage containers 14, 16 does not stand on the tunnel track 10, but on a track 100 of the same track width, which is supported by a long driving platform 102.
  • the driving platform 102 has an endless conveyor belt 104 which extends over its entire length, which runs horizontally in the region of the driving platform 102 and which merges into a front, rising section projecting above the driving platform 102.
  • the advantage of this arrangement is that simpler chassis can be used for the storage containers 16, and indeed without their own conveyor belts, but with separately lockable floor outlets that are opened one after the other from front to back.
  • the multiple conveyor device 34 and the mixer 52 stand with their chassis 12 on the tunnel track 10.
  • the driving platform 102 is coupled to the chassis 12 of the multiple conveyor device 34.
