Definitions

  • the invention relates to a Gleiswegsan istsmaschine, which is designed to excavate old ballast and Altplanumsschutz Anlagen (PSS) and introduce a new layer protection layer and a new ballast layer.
  • Another aspect of the invention is a trackside remediation method.
  • Track shunting machines of this type of operation are used to rehabilitate existing tracks.
  • the substructure of the track which typically consists of at least one layer of gravel, but usually also under the ballast layer lying layer protection layer, which is required for the sufficient carrying capacity, drainage ability and frost resistance of the track.
  • This refurbishment is carried out in such a way that a track-bound track reconditioning machine is routed over the track when the track is in place.
  • the track reconditioning machine rolls on a forwardly arranged chassis on the track and the old substructure and with a rear chassis on the track and the new track track substructure.
  • the renovation of the substructure is carried out in the purpose of this on a bridge between front and rear chassis suspended devices the track substructure dig out and bring the new trackbed, compact and the like.
  • the track is usually lifted slightly and remains mounted with the thresholds, but could also be dismantled and mounted in the area between the front and rear chassis such a way that the thresholds are removed from the track, the track strands are spread and passed by the side of the machine to reassemble them at the rear of the bridge, mount the sleepers and place them on the new track substructure.
  • the sleepers and / or the track strands may be replaced at the same time.
  • Track remoulding machines of this type are made, for example DE 198 07 677 C1 or off EP 2 025 810 B1 known.
  • the track substructure is excavated by means of several chains, in particular according to EP 2 025 810 B1 It is intended to improve the efficiency of the track remover machines by the track track substructure is excavated by a total of three excavation chains.
  • a fundamental problem associated with trackside remediation machines is the limitation on the speed of work that is achieved in track-laying.
  • track reassembly In order to reduce the downtime of a track track, as fast as possible track reassembly is sought and this can be achieved in particular if the track reassembly can be carried out at a high speed of the track reassembly and as few or no interruptions of the remedial drive.
  • the problem of transporting the excavated old materials and bringing the newly introduced new materials into circulation has proved to be a limiting factor for this targeted fast track remediation.
  • a treatment technique has proven to be advantageous in which the excavated old ballast is subjected to a treatment in the form of a ballast and thus sharpening of the old ballast. From this gravel preparation, at least a portion of the excavated old ballast can be recovered in such a way that it can be used as a new ballot and thus the Volumes of the abducted old ballast and the approaching Neuschotters be partially reduced.
  • the invention is based on a detailed analysis of the problem of the treatment of the surface protection layer. It has been found that with the methods which are known from the prior art, although in certain cases, a qualitatively sufficient runway protective layer can be achieved by the treatment mechanisms and laying techniques taught there, but this is not guaranteed over the entire length of a track. As a problem that leads to this deficit, it was identified that the quality of the excavated material over the length of a track usually changes significantly. On the one hand, this change may be due to the fact that a level protection layer has been installed at all and in the track track substructure to be rehabilitated, or this is not the case, that is, the ballast bed has been laid on not specially prepared ground.
  • the invention starts with this knowledge and ensures by means of a specific, upstream first processing unit, first of all, a homogenization aimed at in a substantial soil quality feature, by supplying the excavated layered protective layer material to a sieving and / or comminution device by mixing with a liquid processing fluid before the actual processing, in order to sift out or crush at least rocky coarse components of the excavated protective layer so far that they do not exert a significant influence on the quality of the new PSS.
  • this measure according to the invention it is achieved that the quality variations resulting from the excavated waste PSS are reduced in a relevant aspect for the preparation and thus a more homogeneous starting material for the process of the mixture-technical treatment is provided with the addition of a liquid treatment fluid.
  • the track remoulding machine which is to be understood here in particular as a track-bound track reconditioning machine, comprises two excavating devices, namely an excavating device for gravel lying in front in the working direction and an excavating device for the old PSS lying behind in the working direction, this second excavating device also being used for excavating in the previously explained manner from in place of a PSS Soil is formed.
  • the track remover machine may be advantageous to also equip the track remover machine according to the invention with three or more excavation chains in order thereby to lift the layers of the track bed to be rehabilitated in a more selective manner and to recycle them in the machine.
  • Both the excavated ballast layer and the excavated old PSS is conveyed away within the Gleiswegsan istsmaschine by appropriate conveyors of the excavation and fed to corresponding treatment facilities.
  • the gravel layer can be subjected to a screening and sharpening in order to obtain thereby prepared Neuschotter, it being understood that accumulating gravel shares, for example, fall below a minimum size, can also be supplied by means of a corresponding conveyor of the processing unit for the PSS to in the new PSS to be installed.
  • the excavated waste PSS is first fed to a first processing unit in which it can be sieved and / or broken, wherein it is particularly preferred to perform the operations of sieving and breaking successively and to feed only the screened out coarse constituents to the crusher.
  • the small components of the PSS produced in this way can then be supplied to the second processing unit, it being understood that any contaminated or sieved particles below a certain particle size may also be disposed of in a bunker hopper and not delivered to the second processing unit ,
  • a mixer is provided, in particular, it may be a two-shaft mixer, which causes both a homogenization of the old PSS material from the first processing unit as well as an intensive mixing of this material with the liquid treatment fluid.
  • bunkered virgin materials can also be supplied to the mixer on the track rehabilitation train in order to replace spilled components of the old PSS and to provide the required volume.
  • the anti-fouling layer material conveyed out of the mixer is applied, spread and compacted onto the milled soil sublayer by means of an infeed device to thereby provide a strong, drainable and frost-resistant fouling layer for a trackway that can support both high axle loads and high speeds.
  • the ballast bed is then applied to the new PSS introduced in this way, the track is laid, if appropriate, far after the sleepers have been installed, and the ballast is compacted in order to achieve reliable foundation of the sleepers in the ballast bed.
  • This training makes it possible to use material components that are no longer suitable for use in the new ballast bed due to their insufficient size for the new PSS in the course of ballast processing, which is advantageously achieved that these ballast fractions on the one hand not be stored on the train path rehabilitation train and also volume losses incurred in the PSS processing can be compensated by additions from the old ballast, which in turn can reduce or avoid the need to carry new material for the PSS.
  • a particularly efficient preparation of the excavated old PSS is achieved by this is first divided into fine and large components in a screening process, the coarse components are then subjected to crushing and the resulting fractions obtained together with the previously screened fines then be fed to the further treatment.
  • a division into three or more fractions can be done.
  • old PSS fractions which are below a certain particle size, are screened out in such a multi-stage screening process and fed to a landfill because they are not suitable for processing.
  • these non-reprocessable components of the old PSS can be removed from the processing path and transported by the track remover machine to a corresponding material bunker wagon which is carried along in the track remount train.
  • virgin material entrained by appropriate new PSS bunker conveyors from the track rehabilitation train such as sand, clay, gypsum, loam, gravel, or the like, may be supplied to the second PSS conditioning unit for incorporation into the mixer and for the new PSS to compensate for spilled volume fractions from the legacy PSS.
  • the supplied treatment fluid is changed in terms of its composition and thus adapted to qualitatively different compositions of the excavated old PSS.
  • a mixing control unit two liquids, on the one hand a binder fluid, which may substantially contain binder components, and on the other water, are combined and mixed with each other in an adjustable ratio. This mixture is then subsequently fed to the mixer where it is mixed with the solid constituents of the waste PSS and optionally supplied bunkered virgin materials.
  • the proportion of water and its ratio to the binder content of a specific chemical binder liquid other than water has a significant influence on the quality of the processed PSS and this ratio is particularly suitable for adapting the treatment process to different qualities of the excavated PSS.
  • the proportion of water which is fed to the treatment process can be reduced and with excavated PSS with high binding qualities, for example loamy soils, the proportion of binder fluid with binder contained therein can be reduced in order to prevent this the processed PSS is too moist, on the other hand to prevent the prepared PSS is too brittle.
  • the mixing control unit prefferably be signal-technically coupled to a user input unit for inputting a soil condition feature and to set a predetermined, predetermined mixing ratio between water and binder fluid for this purpose from an electronic memory using a soil condition feature received from the user input unit.
  • the mixing control unit is controlled in such a way that, depending on a soil texture feature, the mixing ratio of the two liquids or optionally several liquids is controlled and such type is adapted to the soil condition.
  • soil texture feature for example, the density or the water content or soil type can be used, here with binary criteria such as sandy, loamy, rocky or percentage information of the ingredients can be used.
  • the user input unit may be located on the track rehabilitation machine itself, for example, as a switch or lever that may be moved between two or more positions to thereby characterize and input the nature of the ground.
  • the user input unit may also be separated from the track remanufacturing machine, for example in the form of a computer unit that prepares a longitudinal profile of the ground conditions along the entire track track to be rehabilitated based on data characterizing the ground condition over the length of the track path, and data corresponding thereto generated, which may be used for the mixing control unit as input data to then pass this data to the mixing control unit.
  • the mixing control unit can use these data in accordance with a further determined geographical position of the track remedy, for example by GPS sensors or a track distance measurement of the length covered, and set the corresponding mixing ratio in a spatially resolved.
  • the mixing control unit is signal-coupled to a soil condition sensor for detecting a soil condition feature, in particular with a soil condition sensor arranged and configured to detect the soil condition of the PSS material leaving the first PSS conditioning unit and from this Soil texture feature received from the soil condition sensor from an electronic memory is suitable for this, to set a predetermined mixing ratio between water and binder fluid.
  • Such a soil condition sensor can be designed to provide a continuous measurement, which thus continuously records the soil quality, a quasi-continuous measurement, ie the soil quality is recorded at discrete, regularly successive times or a random measurement, which therefore only occasional, was initiated by the user Performs a recording of soil quality performs time points.
