In track construction, so-called rapid conversion methods are known in which the sleepers and rails of a track grid to be replaced are replaced. The ballast of the track bedding is hereby relocated, but not cleaned or replaced. A desired ballast cleaning can be done in a separate operation with a special machine, which receives the used ballast of the track bedding, processed and immediately afterwards reinstalled.

Often it is necessary not only to renew the track bedding, but also the associated substructure, the so-called Planum. Here, in addition to the ballast layer of the track bedding, it is customary to install or replace at least one further layer, for example a protective layer, a base layer or an arrangement of a plurality of successive protective or base layers. Often this is a non-sustainable substrate removed and replaced by a more sustainable base course structure. As a result, the load-bearing stability of the rail track can be increased.

The fact that the track grid and the track bedding in a single operation and / or removed, the number and duration of the track closures can be reduced. With regard to the entire track construction or conversion, a significantly higher performance can be achieved than with a temporal or spatial separation of the track grating and track bed related work.

It should be noted that the term "operation" in the context of the present invention is not to be understood as "work step". Specifically, the track grating and track bed related work typically involves several individual work steps. By doing work in a single operation, on the other hand to understand the completion of all required work steps in the immediate chronological order.

The DE 43 39 833 A1 discloses a track construction system for the dismantling and new construction of railways, in which for the supply and removal of material movable and coupled together to trains containers are provided.

In the EP 1 127 980 A2 a track renewal method is disclosed in which the supply of material to the construction site and the removal of material from the construction site are track-bound.

The DE 199 16 585 A1 discloses a system for renewing a track system in which the transport of support layer material by means of a portal loading device takes place. Another portal loading device serves to remove the thresholds.

In the EP 1 775 190 A2 discloses a method for ballast bed cleaning, in which the old ballast and the new ballast is transported by means of containers.

Another railway working vehicle is in EP 2 487 294 A1 described, wherein a through the track worker train passing rail transport application applies.

A problem with existing track-laying systems is that only existing, possibly recycled, material can be used for the ballast bed and sub-base layers. If this already has a strong wear, it may be that the rehabilitated railroad track does not have the desired stability. In addition, it is difficult to coordinate the various operations of "track-track renewal", "ballast bed cleaning" and "track-improvement" including the corresponding machine use. In addition, the performance of existing refurbishment machines is low. This applies in particular to discontinuously operating machines, which, for example, replace a track grate on a yoke basis, that is, piece by piece.

It is an object of the invention to enable a faster, more flexible and more effective new production, rehabilitation or disassembly of railways.

The object is achieved by a method for the new production, renovation or dismantling of a railroad track with the features of claim 1.

According to the invention, during the operation of installing the substructure or part of the substructure, the track grid and the track bedding, material for the track bedding to be installed, such as new ballast, and at the same time material for the substructure or part of the substructure to be installed, such as new sand or new gravel, be transported on track and / or that in the operation of removing the existing track grid, the existing track bedding and the existing substructure or part of the substructure material of the developed track bedding, such as old ballast, and at the same time material of the removed substructure or part of the substructure, such as old sand or old Soil, transported by rail. This eliminates the restriction to on-site existing used material. Due to the track-bound transport, the supply of new material is also possible in areas of a railroad, the environment of which is not accessible or difficult to access.

Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.

It is preferably provided that the track-bound transporting material for the track bedding to be installed, material for the track grid to be installed and material for the substructure or part of the substructure to be installed takes place at the same time and / or that the track-bound removal of material of the removed track grid, material of the dismantled track bedding and made of material of the removed substructure or part of the substructure at the same time. As a result, the construction time can be shortened considerably.

Furthermore, it can be provided that the track-bound transporting material for the track bedding to be installed and material for the substructure or part of the substructure to be installed takes place without intermediate storage and / or that the track-bound removal of material of the dismounted track bedding and of the removed substructure or part of the Substructure without intermediate storage takes place.

The track-bound transport and / or removal of material may be on at least one transport path of a railway vehicle be performed on which transport body for objects or transport body forming objects in the form of cargo along the railway vehicle are movable.

According to one embodiment of the invention, in the operation of installing the substructure or part of the substructure, the track grid and the track bedding at least one protective layer for the substructure, in particular a layer protection layer, an antifreeze layer and / or a water protection layer installed. Such additional sub-layers may e.g. Sand, gravel, special grain mixtures such as KG1 and KG2 and / or asphalt. The corresponding materials are preferably also transported in new condition track-bound, for example, in transport containers on a transport path of the conversion performing machine. By incorporating additional layers into the substructure, the stability of the railroad track can be significantly improved, especially if virgin material is used.

It is also possible to install a plurality of protective layers for the substructure, wherein at least between two of the plurality of protective layers a separating layer is incorporated, which in particular comprises a geotextile and / or a rigid foam material. Such separation layers can counteract unwanted mixing of the materials of adjacent protective layers. In addition, it can be prevented so that the voltage applied under the base layers soil mixes with the bottom layer of support and this is dirty and impaired in their capacity.

Furthermore, the surface of the built-in protective layer or the plurality of built-in protective layers can be sealed, in particular by applying cement. In this way, penetration of water into the protective layer can be prevented.

According to a further embodiment of the invention, the built-in protective layer or the plurality of incorporated protective layers are at least simply reinforced, in particular using a geogrid, a metal mat or a stretch sheet. The substructure can thereby be reinforced.

According to one embodiment of the invention, the built-in protective layer (s) are reinforced using a metal mat which is made of wires during rebuilding or rehabilitation of the railroad track. The wires can be carried along on the relevant machine or fed by rail, so that the reinforcement can be carried out continuously without time delay. A special embodiment of the invention provides that individual entrained or tracked supplied wires are welded to a grid before installation in the machine in question.

Alternatively or additionally, the built-in protective layer or layers may be reinforced using a stretched sheet produced by re-forming a coil during the rebuilding or rehabilitation of the railroad track.

Preferably, at least one protective layer to be incorporated is incorporated in a plurality of partial layers, wherein preferably each partial layer is compacted before the application of a subsequent partial layer. The compaction can be done with a profiled compression element to effect a strong interlocking of the layers with each other. The Gradual introduction of a protective layer in several, relatively thin sub-layers facilitates the compression process.

Furthermore, at least one built-in protective layer or partial layer of a protective layer can be roughened before the application of a subsequent protective layer or partial layer of the same protective layer. As a result, the interlocking effect between individual layers or partial layers can be improved and thus the overall stability of the substructure can be increased. In particular, when a layer is compacted, a profile can be produced which favors a toothing effect.

According to a further embodiment of the invention, during the installation of the substructure or part of the substructure, the number and the thickness of the incorporated protective layers are changed depending on the nature of the soil. The built-in layers can be dynamically adapted to the changing soil conditions.

It can be provided that the installation of the substructure or part of the substructure, the track grid and the track bedding is carried out by a railway work vehicle, wherein at least one carried on the railway work vehicle track of a geo-material, in particular a geosynthetic material, a geotextile or a Geoverbundstoff, in the Substructure or part of the substructure is installed. Compared with the procedure customary in the field of supplying webs of geoparticulate separately and laying them out before commencement of construction along the railroad track, the construction time itself can be considerably shortened by carrying along the webs on the track construction machine itself. A particular advantage is that track closures can be avoided for those rail vehicles that deliver the trains. Furthermore, in the conventional procedure, the prepared Railways are introduced by hand in a laying device of the track construction machine, which can only be done with the machine stopped and is tiring for the construction staff. These disadvantages can be avoided by carrying the geo-material webs on the track-laying machine.

The at least one web of geo-material can in particular be carried along in the rolled-up and / or folded state on the railway work vehicle and automatically removed for installation. For example, the web can be folded once completely in the longitudinal direction and then either rolled or folded in the transverse direction. Before installation, the web can then be automatically unrolled or unfolded by means of a suitable device. Once the web has been completely laid, preferably a further web carried on the railroad work vehicle is automatically provided. Preferably, the threading of this further web is carried out automatically.

Furthermore, the at least one web of geo-material may be carried on the railway work vehicle as a reel wound around a reel axis, the reel axis being parallel to the working direction of the railway work vehicle and the web automatically being unrolled and rotated for laying, preferably by 90 °. This takes into account the fact that common geo-material webs are significantly wider than the railroad work vehicle intended for transport. Due to the storage of the corresponding role transverse to the unwinding direction, the roller itself can in principle be arbitrarily wide.

According to a particular embodiment of the invention, multiple webs of geo material are laid side by side by means of an automatic laying device of the railway work vehicle. This is enough to carry relatively narrow rollers on the railway work vehicle, which is a considerable advantage in terms of storage and handling. In particular, such narrow rollers can be transported and unrolled as needed both in the direction of travel and transversely to the direction of travel.

Furthermore, during the removal of the existing substructure or part of the substructure, the track bedding of an adjacent rail track can be supported, in particular by a follower shoring. This is particularly advantageous if the total thickness of the layers to be removed and installed in the substructure exceeds a predetermined limit.

According to a further embodiment of the invention, a material is used for installing the substructure or part of the substructure, which material was taken during the operation of dismantling the existing substructure or part of the substructure. As a result, the amount of new material to be promoted can be reduced or it can be completely dispensed with the supply of virgin material.

If necessary, after removing the existing substructure or part of the substructure and before installing the substructure or part of the substructure, the soil can be conditioned by applying a preferably pourable stabilizing agent, in particular lime or cement, in particular the stabilizing agent being transported by rail. As a result, the load capacity of the rail carriageway can be further increased.

It is preferred that the rails for the rail track to be installed are transported by rail and / or that the rails of the removed rail track removed, especially in each case without clipboard rails on the ground. This increases the efficiency of the overall process.

The rails of the removed track grid can be divided before removal to ensure better handling.

According to a further embodiment of the invention, it is provided that the rails for the track grid to be installed are transported by rail together with material for the track bedding to be installed and / or for the substructure or part of the substructure to be installed, such as new gravel or new sand, and / or that the rails of the removed track grid together with material of the dismantled track bedding and / or the dismantled substructure or part of the substructure, such as old gravel or used sand, be transported track-bound. The process of the entire track creation, track removal or track rehabilitation can be further accelerated. The transport can be carried out on one or more transport lanes of the railway track conversion work vehicle, advantageously bulk goods are transported in specially provided transport containers and cargo such as rails, sleepers and track grating pieces on one and the same transport path.

Preferably, the arrival and / or removal of the rails takes place without violating the clearance of a train traveling in an adjacent railroad track. The opposite track to be created, to be renovated or disassembled railroad track must therefore not be blocked to carry out the construction work.

According to a further embodiment of the invention, after the existing substructure or part of the substructure has been removed and prior to installing the substructure or part of the substructure, the soil is compacted to provide a more stable foundation for the railroad track to be created.

Further, according to one embodiment of the invention, the moisture of the soil to be compacted is measured and, prior to compaction, water is introduced into provided material for the substructure or part of the substructure to be installed, depending on the measured moisture. Thus, the moisture of the soil can be adapted exactly to the requirements of the compaction process. Likewise, the moisture of the material to be installed can be measured and adjusted as needed.

In certain applications, it may be preferred that during compaction a measured variable, in particular the acceleration, of a compressor element is detected and at least one compression parameter is adjusted as a function of the detected measured variable. In this way, a permanent compression control is possible. If necessary, the compression process can be controlled with a corresponding control device. Furthermore, the collected data can be stored continuously for later use.

According to a further embodiment of the invention, when installing the track bed depending on a local load situation, new ballast, used ballast or recycled ballast is used. For example, at points important for carrying capacity, such as in the area of the carrying head under the track or in front of the head, targeted new ballot can be used, while less in terms of carrying capacity important places, such as in the area of the middle of the sleeper or in the case of double-track railways in the area between the two carriageways, used ballast is used. Thus, the need for Neuchotter can be kept low and yet a high stability of the track bedding can be achieved.

If necessary, in the operation of installing the track bed the built-in ballast can be compacted, in particular before installing the track grid. If necessary, the built-in ballast can be stuffed and / or dynamically stabilized after installing the track grid. The plugging or the dynamic stabilization can also be repeated several times, if necessary. As a result, separate compression, stuffing and stabilization processes can be saved. By sufficient compaction of the basic ballast, a stuffing passage can optionally be saved.

The built-in track bedding can also be profiled, such profiling, if necessary, can also be done several times in a row.

According to a further embodiment of the invention, the position of the installed track grid is detected and documented during the operation of installing the track grid.

Furthermore, in the operation of installing the track grid, the small bars of the installed track grid can be closed, in particular screwed.

For carrying out a method as described above, in particular a railway work vehicle can be used. Prefers a single railway work vehicle will be used for all process steps.

The rails for the track grid to be installed and / or the rails of the removed track grid can, according to one embodiment of the invention, be conveyed through the rail vehicle on a rail conveyor track arranged in or on a railway vehicle, preferably between the wheel disks. This facilitates track installation and / or track removal in hard to reach places. Furthermore, the blocking pause for the arrival and removal of the long rails can be saved. By providing rail conveyance in the typically poorly usable clearance space between the wheel discs, the remainder of the well-usable clearance space of the railway vehicle is free to carry further material, e.g. of bulk material in appropriate transport containers.

According to one embodiment of the invention, the rails are conveyed on at least one rail conveyor track which is provided on one side of the railway vehicle, the rails preferably being conveyed on a plurality of rail conveyor tracks arranged one above the other or side by side. It can also be provided on each side of the railway vehicle several superimposed or juxtaposed rail conveyor tracks. Thus, for example, two rails required for a track grid can be transported to one side of the railway vehicle, while two rails of a removed track grid are transported away on the other side of the railway vehicle. In the central area of the light space of the railway vehicle can then simultaneously material such as new ballast or Neuschwellen transported and possibly used material such as old ballast or old sleepers are transported away.

It may be favorable for certain track construction work, that the rails of the removed track grid, especially the side of the railway vehicle, taken from the ground and transferred for removal to a rail vehicle or in the rail vehicle and preferably arranged between the wheel discs rail conveyor and / or that the rails for the track grids to be installed are transported on a rail conveyor track arranged in or on the railroad vehicle and preferably between the wheel disks and are transferred laterally from the railway vehicle or under the railroad vehicle to be deposited in an area. The subsidized rails can hereby be taken or stored both between the rails of the existing track and next to the rails of the existing track. An arrangement of the rail conveyor track above the wheel shafts is preferred.

A further embodiment of the invention provides that the rails are pulled by means of a traction transfer device, in particular rope, belt or chain, on a rail conveyor of the railway vehicle and / or from this, in particular a retraction of traction transfer devices in the rail conveyor track by means of pulled down from the rail conveyor track Rails done. This allows a particularly simple transfer of the rails on the rail conveyor. It can be provided that a rope, a belt or a chain is pulled into the rail conveyor track before the rail to be pulled in. A threading aid, for example in the form of an arrowhead-type component, can also be attached to a front end of the rail in order to facilitate the threading of the rail into the rail conveyor track. Likewise, at the end of a rail a rope to be attached. When this rail is pulled out of the rail conveyor, the cable is pulled into the rail conveyor. Furthermore, it may be advantageous in certain applications to cut the rails for track-bound transport and / or for track-based removal and spend in a transport container. Preferably, the conveyance of the rails, in particular including the input and / or Ausfädelns in the railway vehicle and / or in the rail warehouse, done automatically. This can further accelerate the overall process.

If necessary, the rails for the track grid to be installed and / or the rails of the removed track grid can be temporarily stored on the ground, in particular on bearing rollers arranged on the floor. Such bearing rollers reduce the required tensile force for the transport of the rails considerably. The bearing rollers can be placed on the ground by the machine that is producing the track preparation, the track restoration or the track dismantling and, if necessary, be picked up again after the discarded rails have been taken up again.

The invention also relates to a railway work vehicle according to the present claim 18, which is designed to carry out a method as described above.

The railroad work vehicle comprises at least one transport path on which transport objects for items or transport body forming objects in the form of piece goods along the railway work vehicle are movable, and a structural module for installing the track grid and material of the track bedding and material of the substructure or part of the substructure and / or a structural module for removing the Track grids and material of the existing track bedding and material of the existing substructure or part of the substructure. If desired, the railroad work vehicle may additionally include at least one recycle module separate from the building module or modules for cleaning up removed material. Thus, a track renewal can be combined with a ballast bed cleaning and so in particular the lock time are kept to a minimum.

Furthermore, the railway work vehicle preferably comprises a device for releasing and / or fixing of iron. This facilitates the continuous installation of the track grid and removal of the existing track grid.

The railway work vehicle according to one embodiment of the invention may also include a device for receiving and transporting the rails of the removed track grid. Furthermore, the railroad work vehicle may include a compacting device such as a driven vibratory plate or a vibratory roller. Alternatively or additionally, the railroad work vehicle may include a stuffing and / or profiling device.

At the in Fig. 1 Rail track 11 shown is the track grid 13 with rails 15 and sleepers 17 laid in a track bed 19 made of gravel. The track bed 19 is applied to a protective layer 21 and this in turn on the substrate 23. The protective layer 21 may be, for example, a layer protection layer of a grain mixture. The protective layer 21 and the substrate 23 together form a substructure 25 of the rail track 11, which may comprise further layers depending on the design. If the substructure 25 more Layers, these may be separated by geopressure layers or the like.

The new production, renovation or dismantling of a Fig. 1 designed rail carriageway 11 is carried out according to the invention of a Eisenbahnarbeitsfahrzeug, which hereinafter with additional reference to Fig. 2 will be described in more detail.

This in Fig. 2 illustrated railroad work vehicle 27 according to the invention comprises a chassis 29 carried by a chassis 31 and a plurality of worn by the chassis 31 working equipment, of which only an excavating device 33 and a mounting device 34 are shown by way of example.

The chassis 29 is a rail undercarriage in the illustrated embodiment. Instead of a rail chassis or in addition to a rail chassis, a ground gear, e.g. a crawler undercarriage, be provided. This makes it possible for the railroad work vehicle 27, at a new production of a railroad track at least in its seen in the direction of the front part to operate without a track.

Above the working devices 33, 34, a transport path 35 is provided on which transport bodies 36 for goods can be moved along the railway work vehicle 27. The transport path 35 is here designed as a roller conveyor with rollers 37, on which the trained as boxes transport body 36 can be moved. To move the transport body 36, the rollers 37 or at least individual rollers 37 can be driven in rotation. It should be noted that in Fig. 2 merely by way of example a single transport track 35 is shown. Depending on the purpose of the railway work vehicle 27 be provided further transport paths, wherein the plurality of transport paths, for example, parallel to one another next to each other and / or arranged one above the other.

The transport bodies 36 can accommodate all types of goods, in particular working materials such as gravel, sand, gravel, cement, sleepers, iron, platelets, asphalt, soil conditioning substances, piling and signal foundations, but also supplies such as fuel and water. They can serve both to supply and to dispose of the working devices 33, 34 of the railway work vehicle 27.

The transport body 36 can be loaded, for example, via an unillustrated conveyor belt with excavated material of the excavating device 33.

For supplying the installation device 34 may also be in Fig. 2 not shown conveyor belt may be provided, which can be filled, for example via a corresponding filling with material from the transport bodies 36. For this purpose, a likewise not shown device for emptying the transport container 36 may be provided at a filling position.

To rehabilitate or disassemble an old railroad track 11, the existing railroad grating 13 is first removed by the railway work vehicle 27. For this purpose, the iron is automatically solved by a corresponding, preferably in the railway work vehicle 27 integrated device.

Subsequently, the used rails 15 are spread out from the sleepers 17 and deposited on a rail conveyor track 39 provided laterally on the chassis 31 of the railroad work vehicle 27. The rail conveyor track 39, like the transport track 35, has rollers 37, of which optionally at least some are rotatably drivable. If desired, therefore, the stored used rails 15 can be transported away directly in or against the working direction I.

Furthermore, the used sleepers 17 are picked up by a suitable device integrated into the railroad work vehicle 27 and brought into one or more of the transport bodies 36. By means of the transport body 36, the used sleepers 17 can be easily transported away on the transport path 35 in or against the working direction I. If the used sleepers 17 can not be transported because of their poor condition, they can also be deposited next to the rail track 11 and can only be picked up manually after the remediation process has been completed.

Subsequently, the expansion of the track bed 19 and the substructure 25, preferably in several individual layers. For example, for this purpose, the excavating device 33, optionally in conjunction with other devices used. The gravel of the developed track bed 19 and the material of the developed layers of the substructure 25 is placed in one or more of the transport body 36 and transported on the transport path 35 either for disposal or fed to a recycling process.

If a deconstruction of the rail track 11 is desired, the process ends here. Otherwise, the soil will be watered as needed, conditioned and compacted by applying lime or cement. Subsequently, a new substructure 25 is installed, for example by means of the installation device 34. Here again, at least one protective layer 21 is incorporated, preferably in several thin layers. The material required for this purpose is transported in transport bodies 36 on the transport path 35.

After completion of the new substructure 25, a new track bed 19 is installed and compacted as needed. The ballast for the track bed 19 is in turn transported in transport bodies 36 on the transport path 35.

Once the new track bed 19 is completed, new sleepers 17 are placed in the track bed 19. Subsequently, new rails 15 are transported to the rail conveyor track 39 and automatically threaded into the rail storage of the stored sleepers 17. The preferably automatic transport of the new rails 15 can in this case on a further, in Fig. 2 invisible rail conveyor on the other side of the railway work vehicle 27. In order to allow a simultaneous conveyance of four rails 15, for example, two used rails 15 of the removed track grid 13 and two new rails 15 for the new track grid 13 to be installed, 27 two superimposed rail conveyor tracks 39 may be provided on each side of the railway work vehicle. Optionally, further rail conveyor tracks 39 are provided, on which a transport of long rails through the railway work vehicle 27 can take place. In order to enable a change of transported rails 15 from a rail conveyor track 39 to another rail conveyor track 39, corresponding switches may be provided.

In particular, three pairs of rail conveyor tracks 39 may be provided, one of the pairs serving to convey a pair of rails through the entire railroad work vehicle 27. This makes it possible to deliver the rails 15 for the track grid 13 to be installed, depending on the requirements with respect to the working direction I either from the front or from the back or transport the rails 15 of the removed track grid 13 either forward or backward.

In the further course of the renovation process, the small iron are screwed and if necessary, the rehabilitated railroad track 11 is stuffed once or several times and / or dynamically stabilized.

In the case of a new production of a rail track 11, all steps related to the installation are carried out without first performing the steps related to the expansion.

As a result, the invention enables the renewal, rebuilding or removal of a rail track 11, including an improvement of the substructure 25, in a single continuous process by means of a single, possibly modular machine or by means of a single machine complex.

This in Fig. 2 illustrated railroad work vehicle 27 may form a module of a Eisenbahnarbeitszuges, according to the invention more such modules can be assembled. In this case, each module may have different working devices, but it can also be two or more identical modules are put together. The transport paths 35 and the rail conveyor tracks 39 of the modules are preferably designed so that the transport paths of several modules form a continuous transport path. Also, the transport lanes form with appropriate transport paths of other rail vehicles a continuous transport path, for example, with supply and / or Entsorgungszügen.

Concretely, the supply and removal of material to or from the railroad work vehicle 27 can take place by means of a train of several rail vehicles 28 coupled together, which will be described below with additional reference to FIG Fig. 3 be described in more detail.

The railway vehicle 28 is designed in principle similar to the railway work vehicle 27. However, it is designed as a simple railroad car with a rail 29 and has no working facilities. As with the railway work vehicle 27, a transport path 35 is provided, on which the transport bodies 36 are movable. The transport path 35 is in turn designed as a roller conveyor with rollers 37. It can also be provided further transport paths, wherein the plurality of transport paths, for example, parallel to one another next to each other and / or arranged one above the other. Laterally on the chassis 31 of the railway vehicle 28, a rail conveyor track 39 is provided, which has like the transport path 35 rollers 37. The transport track 35 and the rail conveyor track 39 are designed such that transport body 36 and rails 15 are movable on continuous tracks of railway vehicle 28 to railway vehicle 28 and of a railway vehicle 28 to the railway work vehicle 27 when a train of railway vehicles 28 in Fig. 2 from the left to the railroad work vehicle 27 is coupled.
