Description

The invention relates to a method and a device for creating a new construction route for an at least single-track railway line when the track is not present in the original.

It is known from the prior art that different materials in variable widths and thicknesses are required and installed for the production of a track route, depending on the predetermined cross section of the track route. These layers consist of a base layer, the so-called formation protection layer (hereinafter abbreviated to PSS or PS layer), which consists of gravel-sand mixtures of different compositions or, if necessary, asphalt, and a gravel layer, which consists of gravel stones (hard rock, e.g. Granite) of a certain grain fraction.

The installation of this track underlay in accordance with the rules takes place on an earth level, which is made of stable subsoil, e.g. B. there is gravel or rock. The strength and the cross-profile formation of the individual PS and gravel layers can be very different. Track routes can consist of a single track or several, at least essentially parallel tracks.

So far, the materials for a new railway line, which includes the PS layer and gravel layer, have been transported and unloaded by truck depending on the location if the track is not available. This can also be done with a rail car if there is already a track near the new line. After the materials have been unloaded, they are installed and compacted in layers according to the height, width and cross profile specifications of the system planning. The individual layers are installed in separate work steps. First, the PS layer made of a mixture of gravel and sand must be installed. In individual cases, e.g. B. in Switzerland, this PS layer can also consist of asphalt.

After the PS layer has been installed in accordance with the profile, the ballast layer is installed in a separate operation for the area from the upper edge of the PS layer to the intended lower edge of the sleepers for the new track. Installation is often carried out the new PS and gravel layers with standard construction machinery and equipment in different ways, depending on the location and the construction variant.

The installation work for the PS and ballast layers can be carried out by truck, excavator, caterpillar, roller, paver or the like, whereby it should be noted that the finished PS layer before the application of the ballast layer must not have any unevenness and therefore not with trucks or any wheeled vehicle may be driven on.

Therefore revealed DE 38 34 313 A1 a process for creating a track line, in which a ballast layer is finished using a ballast paver and a prefabricated PS layer is finished using a PSS finisher in front. Both pavers have a crawler chassis so as not to damage the PS layer. When viewed from the front, the PSS finisher has a feed hopper from which a conveyor belt extends to the ballast paver. The feed bunker can be loaded with ballast from a truck, since the section of the prefabricated PS layer used for this purpose is subsequently smoothed and, if necessary, compressed by the PSS finisher.

Alternatively, if available, existing tracks or paths that already exist alongside the track route to be created can be used to supply material. Furthermore, special complex track line construction trains can be used, which install the PS layer and ballast layer in front of the head and apply the track thereon, these construction trains have a running gear on the head for driving on the substructure and in the rear area a rail running gear for driving on the newly laid track.

Describes this EP 2 295 638 B1 a method and a work cart for creating a track body, in which the rails are first placed on the track substructure and applied by the work cart in front of the ballast to the track substructure, then the sleepers on the ballast and finally the previously deposited rails threaded into the work cart become. For this purpose, the work trolley has a crawler track and a rail undercarriage at the rear end and is thus partially moved on the already finished track body. The method can also provide for a PS layer to be applied beforehand below the ballast. To apply the PS and gravel layer, the work trolley each has a corresponding installation device in front of the crawler track, the ones required for installation Materials are fed via conveyor belts from corresponding material trolleys, which are arranged behind the work trolley in the working direction.

Also EP 2 708 648 discloses a device for creating a track, in which the materials required for the installation of the PS layer and the ballast layer are fed via conveyor belts from material wagons which are arranged in the working direction behind the device for creating the track, which separated from leading, separate and decoupled there There are paving machines that have a wheel or crawler chassis, behind which the installation device for the PS layer or the ballast layer is arranged.

Such devices can be used to create a new railway line comprising the PS layer and the ballast layer in a single continuous operation, but these are complex construction trains, which also require a large number of material wagons and corresponding conveyor logistics for material supply, compared to conventional construction methods, in which the PS layer and the ballast layer are created in separate work steps in succession using conventional machines and equipment, significantly more costly.

Starting from this prior art, it is an object of the present invention to provide a simplified, faster and less expensive continuous method for creating the PS and gravel layer of a new building terrace without damaging a PS layer created during construction and without requiring it To use parallel paths or tracks.

This object is achieved by a method with the features of claim 1.

The further object of providing a device suitable for carrying out the method is achieved by the device having the features of independent claim 9.

Further developments are set out in the respective subclaims.

The method according to the invention relates to the construction of a new construction route for an at least single-track railway line when the track is not present as an exit.

"Track not present at the beginning" refers to the condition of the planned new line before the start of the procedure, i. H. the procedure is used in an initial situation in which there is no existing railway track along the planned new construction route.

In other words, it is a method for the first erection of an at least single-track railway substructure, whereby in the present case, "substructure" is understood to mean the PS layer built up on the ground level and the ballast layer or ballast bed built thereon. The procedure does not refer to the rehabilitation of these layers on an existing railway line.

A first embodiment of the method according to the invention, in which the PS layer is built up on the earth level and the ballast layer on the PS layer in one working direction in a continuous workflow, comprises the construction of the PS layer by a formation protection layer paver (PSS paver) ) and the building up of the ballast layer is carried out by a ballast bed paver. The ballast paver is operated at a predetermined distance with respect to the working direction behind the PSS paver on the PS layer built up by the PSS paver. In order not to damage the PS layer, a ballast paver equipped with a crawler or crawler chassis is used. In order for the two paving machines to build up the two layers simultaneously and continuously, the method further comprises feeding the materials required to build up the PS layer and the ballast layer from one or more bunker wagons to the PSS paver and the ballast bed paver, using appropriately assigned conveying devices that extend from the bunker wagon (s) to the PSS paver and the ballast bed paver, respectively. The one or more bunker wagons are operated at a predetermined distance in relation to the working direction in front of the PSS paver. H. moving at the same speed as the PSS paver and the ballast bed paver in a continuous workflow in the working direction, while the material feed from the bunker wagon via the conveyors to the paver finisher is in the opposite direction.

In the method according to the invention, paving machines known per se for the PS layer and the ballast layer are now used in connection with bunker wagons and conveying devices in an advantageous working constellation, which involves the creation of a New construction terrace with a track that does not exist as a starting point in a continuous workflow with simultaneous build-up of PS layer and ballast layer in comparison to the prior art not only significantly simplified and at the same time made faster, but also more cost-effective, since complex machine trains that require material supply can be dispensed with are dependent on track-bound material wagons. Damage to the PS layer by the ballast bed paver is avoided by the ballast bed paver having a chain or crawler track. PSS pavers and bunker wagons traveling on the ground level can preferably also have a track or crawler chassis, which is particularly advantageous in wet weather.

Although the different materials required to build up the layers, e.g. B. for the PS layer a gravel-sand mixture or possibly asphalt and for the gravel layer of gravel of a certain grain - can be presented in a single bunker car, which can have correspondingly separate sections for this purpose, can be in a further advantageous embodiment of the invention The method can be provided that a separate bunker car is used for each of the different materials, d. that is, the material required for the PS layer is stored on a first bunker wagon and the material required for the ballast layer is stored on a second bunker wagon. The material required for the PS layer is then transported from the first bunker wagon via the associated conveyor to a receiving device of the PSS paver. Correspondingly, the material required for the ballast layer is transported from the second bunker wagon, which is operated next to the first bunker wagon, via the associated conveying device to a receiving device of the ballast bed maker.

In a particularly advantageous development of the method, it is provided that a ballast bed paver is used for each new track to be built for a new track for a double-track or multi-track railway line. Since the two or more ballast bed pavers are used next to each other, the ballast beds of the new construction terrace for the two or more track line are manufactured at the same time. Depending on the width of the new construction terrace, a single PSS paver may be sufficient, behind which the two or more ballast bed makers build the ballast beds next to each other on the PS layer. Each ballast bed maker is supplied with the material required to build up the respective ballast layer from the at least one bunker wagon via a correspondingly assigned conveyor device; is preferred however, a separate bunker wagon is provided for each ballast bed paver, from each of which a conveyor extends past the PSS paver to the assigned ballast bed paver. The two or more bunker wagons used in accordance with the two or more ballast bed pavers are preferably arranged next to one another and next to the bunker wagon which is assigned to the PSS paver. As an alternative to the parallel use of e.g. B. two ballast bed makers next to each other to create the ballast beds of a two-track railway line, a process variant can provide the use of a special ballast bed maker that has two installation devices that are arranged side by side for the installation of the two parallel ballast layers.

Depending on the number of track sections and their track width or the total width of the new construction line, more than one PSS paver may be required. Then, in a further development of the method according to the invention, two or more PSS pavers can also be used side by side, to which the required material is fed from the leading bunker wagon, preferably each from its own leading bunker wagon, via an associated conveyor.

The materials required for the PS layer and the ballast layer are each installed by an installation device of the PSS paver and the ballast bed maker, the installation device of the PSS paver the PS layer and the installation device of the ballast bed manufacturer the ballast layer in each case according to one for the PS -Layer and the gravel layer incorporates predetermined profile. The respective profile can be specifications for z. B. include height, width, shape, location and inclination of the respective layer.

A further embodiment of the method according to the invention relates to the linking and automation of the workflows of the method and includes measuring, leveling and recording the heights and lateral positions of the earth plan, and taking these heights and lateral positions of the earth plan into account when determining the respective profile of the PS Layer and the gravel layer. Measurement and leveling devices, which are linked to the respective installation device via at least one control device, can preferably be used for measuring, leveling and detecting the heights and lateral positions of the ground level the installation of the PS layer and the ballast layer with the respective predetermined profile takes place automatically.

The measurement is usually carried out using a guide cord previously measured on the side edge, which can be a wire cord, for example. The guide cord is used as a tactile line for the paver, who continuously picks up the measurement there during the forward movement. An alternative method variant can provide a directional line controlled by a laser point.

The automation of the process sequences is made possible by the use of the leading bunker wagons, which ensure a continuous material supply not only when building up the ballast layer but also when building up the PS layer. In this way, material accumulations are avoided which were used for the material supply in the prior art when the PS layer and the ballast layer were built up separately in a discontinuous manner. The discontinuous material supply by means of fillings always requires new starting points when installing the layers in order to obtain the desired profile, which is also avoided with the method according to the invention. The layered continuity and homogeneity of the PS layer and the ballast layer can therefore advantageously be achieved more easily by the method according to the invention.

In order that the method can be carried out in a uniformly continuous workflow, a further development of the method according to the invention provides that, on the one hand, a driving speed of the PSS paver, the ballast bed paver and the at least one bunker wagon are coordinated with one another, so that the paving machines and the bunker wagons essentially be moved forward at the same speed. By suitable selection of the distances, which are predetermined between the ballast bed paver and the PSS paver as well as the PSS paver and the bunker wagon, certain fluctuations are acceptable and can be compensated for as long as the discharge end of each conveyor device is above the receiving device of the associated paver. If the receiving device extends over a larger area of the paver, there are also sufficient tolerances for fluctuations. The leading bunker wagons are preferably operated separately from the paver-builders and accordingly have their own drive. When the drives of the bunker wagons and paving machines are operatively coupled to adapt to the same speed at which the bunker wagons and the paver workers are moved forward, the conveyor between the respective paver and the assigned bunker car may have a fixed connection or support.

Furthermore, the method in this development comprises coordinating the installation speeds of the PSS paver and the ballast bed paver as well as coordinating the driving speed of the PSS paver, the ballast bed paver and the at least one bunker wagon with the installation speeds of the PSS paver and the ballast bed paver. Furthermore, a conveying speed of the conveying devices is matched to the paving speed of the PSS paver and the ballast bed paver. This can preferably be controlled or regulated electronically.

To optimize the built-in layers, in a further embodiment of the method according to the invention, additional leveling and / or compacting of the PS layer and / or ballast layer built up can take place, for which purpose a corresponding leveling and / or compacting device can be used which - in relation to the working direction - is arranged behind the installation device of the PSS paver or the ballast paver. In principle, leveling and compaction work is already carried out by the paver's paving equipment; The additional leveling and compacting units, which are arranged in the wake of the paver, enable optional or repeated subsequent processing of the material installed by the paver.

In a preferred embodiment of the method according to the invention, the loading of the at least one bunker wagon with the materials required to build up the PS layer and the ballast layer can be carried out by one or more trucks which approach the at least one bunker wagon from the front in relation to the working direction via the ground level that can be driven with wheel tires. The delivery of materials by truck is associated with significantly less costs than the use of track-bound material trucks. The bunker wagons are preferably designed in such a way that the loading can be carried out simply by tipping the load of the truck, which is placed in front of the bunker wagons to be loaded in the working direction.

It is envisaged that the forward movement of the bunker wagon to be loaded - and corresponding to the other bunker wagons and paving machines - will continue during the docking and tipping of the truck to the bunker wagon to be loaded so that the process continues in the working direction even while the bunker wagon is being loaded. For this purpose, after the truck is docked to the bunker truck to be loaded and the unloading process begins, the truck is switched to idle, so that the truck is pushed into the work process until it is completely unloaded.

A further subject of the invention is a corresponding device for creating a new construction route for an at least single-track railway line or for the first erection of an at least single-track railway substructure in the case of a track which does not exist initially, and which the method according to the invention can carry out. For this purpose, the device has, in a specific working constellation, at least one PSS paver, at least one ballast bed paver that is equipped with a crawler or caterpillar undercarriage for driving on the PS layer, at least one bunker wagon and conveyor devices that are assigned to the PSS paver and the ballast bed paver are. In the work constellation, the ballast bed paver can be operated at a predetermined distance in relation to a working direction behind the PSS paver, the bunker wagon can be operated at a predetermined distance in relation to the working direction in front of the PSS paver, and the conveying devices extend from the at least one Bunker wagons according to the assignment to the PSS paver and the ballast bed paver.

The conveyor devices of the device according to the invention can preferably be conveyor belts or belt conveyors; however, other conveying devices such as screw conveyors, trough chain conveyors or bucket elevators are also conceivable.

In a preferred embodiment, the device has at least two bunker wagons which can be operated next to one another, a first bunker wagon being assigned to the PSS paver and a second bunker wagon being assigned to the ballast bed paver. The PSS paver and the ballast bed paver each have a holding device, which can be designed, for example, simply in a box-like manner without a lid, but with a large opening area. To this receiving device or, more precisely, to its opening area, the respectively assigned conveying device extends from the first bunker car and the second bunker car in accordance with the assignment. It can be provided that each conveyor device can have a fixed connection or support to the assigned paver - but the discharge end of each conveyor device can also have a fixed connection or support above the respective one Be positioned device. In a special development, the conveyor devices can be adjustable in length, position and / or angular position, so that a discharge end of the conveyor device can be variably positioned in relation to the receiving device. As a result, on the one hand, different paving machines can be used in a device according to the invention in that the discharge end of the conveying device can always be aligned appropriately, and on the other hand the predetermined distance of the paving machine from the bunker wagon can be varied. In addition, an adjustable conveyor device can also be used to ensure that the discharge end is always positioned above the receiving device, regardless of the course of the railway line and the topography, ie also in curves or waves in the course of the route.

In a further development, the device according to the invention can have a ballast bed paver for each track to be built, two or more ballast bed paver in the working constellation being able to be operated side by side. The device can preferably have an assigned bunker wagon for each ballast bed paver, as a result of which the conveying devices can simply run parallel to the working direction and extend from each bunker wagon to the assigned ballast bed paver. Optionally, depending on the width of the new construction terrace, the device can also have more than one PSS paver, the PSS paver also being able to be operated side by side in the working constellation and preferably each being assigned to its own bunker car. An alternative working constellation looks instead of e.g. B. two or more ballast bed pavers next to each other in front of a special ballast bed paver, which has two or more installation devices according to the track sections to be installed, which are arranged side by side for the installation of the parallel ballast layers. Such a special ballast bed paver can have a separate receiving device for each paving device, to which material is fed from an assigned bunker wagon via a corresponding conveyor. If this special ballast bed paver only has one receiving device that supplies both installation devices with ballast, the material can be fed from a single assigned bunker wagon into the single receiving device via a corresponding conveyor device.

The PSS paver and the ballast bed paver each have an installation device which, in a preferred embodiment of the device, is designed in each case for the PS layer and the ballast layer in accordance with one for the PS layer and one for each Gravel layer of predetermined profile, which may include height, width, shape, location and inclination. For automation, the device can optionally also have measuring and leveling devices for measuring, leveling and detecting the heights and lateral positions of the ground level, which are linked to the respective installation device via at least one control device in order to predetermine the installation profile which the respective layer to be installed should have . As an exemplary measuring and leveling device, each paver can have a feeler device to sense a guide cord previously measured on the side edge of the new construction terrace. Another example of a surveying and leveling device can use a laser point controlled direction line.

In a further embodiment of the device according to the invention, at least the drives of the PSS paver, the ballast bed paver and the at least one bunker wagon and the installation devices and the conveying devices can be linked electronically, possibly via a control or regulating device, to automate the work processes in particular to coordinate a driving speed of the PSS paver, the ballast bed paver and the at least one bunker wagon and an installation speed of the PSS paver and the ballast bed paver. Furthermore, preferably also via the control device, a conveying speed of the conveying devices can be matched to the installation speed of the PSS paver and the ballast bed paver.

Another embodiment of the device according to the invention provides that the PSS paver can have an additional leveling and / or compacting device, which can be used for additional or repeated subsequent leveling and / or compacting of the installed PS layer in relation to the working direction behind the paving device of the PSS paver is arranged. As an alternative or in addition, the ballast bed paver of the device according to the invention can also have an additional leveling and / or compacting device which is arranged behind the installation device of the ballast bed paver in relation to the working direction.

A further development relates to the fact that the device has at least one truck that can be operated in relation to the working direction in front of the at least one bunker wagon in order to load the bunker wagons with the respective material.

Until now, the construction of new lines for track systems has required two separate work steps for the construction of the PS layer and ballast layer, if no complex track-bound construction trains are used, which do the construction of the two layers with special devices in front of the head, which at high cost connected is.

Fig. 12 illustrates in a simplified representation the construction of a single-track railway line 100, which has the route built on the ground level 1 from PS layer 2 and gravel layer 3. The sleepers 4 (of which in the sectional view in Fig. 12 one can be seen) on which the rails 5 are fastened. The earth level 1 denotes the surface of the ground, which is machined accordingly in terms of flatness, inclination and position in accordance with the profile. It can be seen that the earth level 1 is inclined roof-shaped in order to be able to drain surface water safely. In the example shown, the PS layer 2 built up on the earth level 1 has a profile with corresponding roof-shaped inclinations, while the ballast layer 3 built up thereon has a different profile with an approximately flat surface for the track made of sleepers 4 and rails 5.

The profiles of the PS layer 2 and gravel layer 3 shown are to be understood as examples. Modifications of the new terrace to be created with different profiles of the layers with regard to layer thickness, layer width and layer inclination as well as deviating heights and lateral positions of the new building terrace are included within the scope of protection.

The method according to the invention, which is carried out inexpensively with a device according to the invention, now enables the parallel installation of the PS and ballast layer 2, 3, without being driven on by wheeled tire vehicles of the new PS layer 2, continuously in one working direction, which is exemplified by the embodiments in FIGS 1 to 11 is shown and is not possible with common techniques, ie without the complex, expensive, track-bound construction trains. As a result of the continuous installation according to the invention without driving with wheel-tired vehicles, in particular the PS layer 2 with the required homogeneity and the predetermined profile is generated virtually simultaneously with the ballast layer 3 built thereon, which is also provided uniformly with the predetermined profile.

In the method according to the invention, which relates to the simultaneous installation of the PS layer 2 and the ballast layer 3, the device is loaded with the materials K, S to be installed from the ground level 1, as shown in the figures. In the following examples, the materials to be installed are a sand-gravel mixture for the PSS and rock ballast for the ballast layer, but should not be restricted to this. An alternative material for the PSS can be asphalt, for example.

Fig. 1a, b shows for loading a truck 15, which is in relation to the working direction A in front of the bunker trucks 10a, 10b, in which the materials K, S are stored. In the working constellation of the device according to the invention, in the embodiment shown, there is a PSS paver 20 behind the bunker wagons 10a, 10b and behind it a ballast bed paver 30, all of which are moved forward uniformly in working direction A at approximately constant speed. The bunker wagons 10a, 10b and the PSS paver 20, which each have a crawler track 11, 21 here, travel over the earth level 1, while the PS layer 2 is built up by the PSS paver 20 on the earth level 1 using the installation device 22 , which is arranged behind the crawler track 21. The ballast bed paver 30 following the PSS paver 20 travels the newly installed PS layer 2 and has a suitable crawler or crawler undercarriage 31 for this purpose in order to prevent the PS layer 2 from being destroyed. The ballast layer 3 is built up in parallel and also continuously on the PS layer 2 by the ballast bed paver 30, which has a corresponding installation device 32 for this purpose, which is arranged behind the crawler or crawler chassis 31.

Both paving machines 20, 30 are continuously supplied with the required materials K, S, the material K required for paving the PS layer 2, which, for. B. can be a gravel-sand mixture, the PSS paver 20 is fed via a conveyor 12a from an associated bunker wagon 10a, in which the material K is stored. Bunker car 10a and the conveyor 12a are hidden in the side view; only the material K falling into the receiving box 23 of the PSS paver 20 at the discharge end of the conveying device 12a can be seen. Correspondingly, the material S required for the installation of the ballast layer 3, usually rock ballast of a certain grain size, is fed to the ballast bed paver 30 via a further conveying device 12b from an assigned bunker wagon 10b, in which the material S is stored. The materials are therefore supplied in a material conveying direction M, which is opposite to the working direction A and allows the device K to be loaded with the materials K, S from the earth level 1 by means of trucks 15, which in the example shown is a tipper. The truck 15 is placed in front of the bunker wagon to be loaded, here the bunker wagon 10a assigned to the PSS paver 20, in such a way that - as in FIG 2a, b can be seen - the material contained in the tipping trough of the truck 15 is transferred in the material conveying direction M when tipping into the bunker truck 10a provided. The continuous installation of the PS layer 2 and the ballast layer 3 is not interrupted here because the truck 15, which was switched to idle after docking with the bunker truck 10a, is pushed forward in the working direction A during the tipping over from the bunker truck 10a.

To start the method according to the invention, if at the beginning only the ground level is available, a first PSS section, the length of which will correspond approximately to the length of the ballast paver, can be prefabricated as a starting contact area for the entire system using conventional earthworks. On this first PSS route section, the ballast bed paver can be taken up to form the work constellation, in that the PSS paver and the bunker wagons with the respective conveying devices are arranged in front of it on the ground level in order to implement the method according to the invention with the components of the overall work constellation working in parallel start from PSS paver, ballast bed paver and bunker wagon at the same time.

The conveying devices 12a, 12b extend from the respective bunker car 10a, 10b to the associated paver 20, 30 or to its receiving box 23, 33. The bunker car 10a, 10b can have a feed hopper, the neck of which is at or above the receiving end the conveyor 12a, 12b opens. The receiving boxes 23, 33 can also be designed as feed hoppers in order to feed the material to the respective installation device 22, 32 directly or via a further conveying device.

That with 3a, b and 4a, b The example shown differs from that in Fig. 1a, b and 2a, b Device shown in the arrangement of the conveyors 12a, 12b, which may be due to a different arrangement of the respective receiving box 23,33 on PSS paver 20 and ballast bed paver 30. If necessary, the different arrangement of the conveying devices and the variation of the discharge position thus achieved enables the respective receiving box to be filled more evenly.

So that differently constructed pavers 20, 30 can be used in a device according to the invention, either different bunker wagons 10a, 10b can be provided, which differ in the arrangement of the associated conveyor device 12a, 12b with respect to their position transversely to the working direction, or the conveyor devices 12a, 12b can be designed to be adjustable in relation to this position, so that depending on the arrangement of the bunker wagons 10a, 10b and on the construction of the pavers 20, 30 used, the discharge end of the conveying device 12a, 12b is optimally positioned in relation to the respective receiving device 23, 33 can.

In addition, the conveying devices, although this is also not shown, can be designed to be telescopic and / or rotatable in order to provide variability in terms of length and / or angular position, and thus the arrangement of the discharge ends even if the bunker wagons and the paver differ to be able to ensure via the receiving devices of the respective pavers.

In Fig. 1a , b to 4a , b the device has a bunker wagon 10a, which is assigned to the PSS paver 20, and a bunker wagon 10b, which is assigned to the ballast bed maker 30, the two bunker wagons 10a, 10b being operated side by side. Of course, deviations from the examples shown are conceivable within the scope of protection, which also extends to work constellations in which a single bunker wagon is used, which has separate sections or separate feed hoppers for the respective materials, so that the conveying devices move away from the respective sections / feed hoppers of the only bunker car to the assigned pavers. Embodiments are also according to the invention in which the bunker wagons are not operated next to one another but one behind the other or offset from one another, the devices in these working constellations having appropriately adapted conveying devices.

The exemplary representation in 7a, b shows how following the construction of the ballast layer 3 by the ballast bed paver 30 of a device according to the invention by arranging sleepers 4 on the ballast bed 3 of the new building terrace, possibly with filling ballast 3 'between the sleepers 4, and by fastening rails 5 the sleepers 4, a single-track railway line 100 is completed. Fig. 7c shows a double-track railway line 101, in which the new construction line has two parallel ballast beds 3 and which can also be created by a method according to the invention with a device according to the invention.

5a, b and 6a, b show an exemplary embodiment of a device according to the invention for creating such a double-track new construction terrace. From the top views in Fig. 5b and 6b it can be seen that the device used for this purpose has two ballast bed pavers 30 corresponding to the two ballast beds 3 to be created, each of which has a track or crawler chassis 31 for driving on the PS layer 2 and is operated at a predetermined distance behind the PSS paver 20, who only installs the entire PS layer 2 here. Here, too, the required material is fed to the PSS paver 20 via a conveyor 12a from the assigned bunker wagon 10a, which in the example shown is arranged between two bunker wagons 10b, in which ballast is stored and each of which has a conveyor 12b for a respective ballast bed paver 30 extends. Here, too, the bunker wagons 10a, 10b are loaded by means of trucks 15 which, as in 6a, b can be seen, transfer the material by tipping into the respective bunker cars 10a, 10b.

Deviations from the example shown are also conceivable within the scope of protection. For example, an alternative can provide that only one bunker wagon is used for the storage of ballast, which, however, is then equipped with two conveying devices in order to feed material to both ballast bed makers. Another alternative for creating a double-track new construction terrace can provide that a single ballast bed paver is used that has two paving devices. Depending on the width of the new construction terrace, more than one PSS paver can also be used. The two PSS pavers can then also be operated next to each other and can be supplied with the material required for paving by appropriate dedicated bunker wagons or by a common bunker wagon.

Furthermore, it goes without saying that for the creation of multi-track new building terraces, i. H. of new construction terraces with more than two line tracks, the number of ballast bed pavers used, possibly also the PSS paver, and the assigned bunker wagons and conveyors can be adjusted accordingly. For example, a working constellation for a three-track new construction terrace can provide for the parallel use of three ballast bed pavers next to each other behind a single PSS paver, which produces the entire width of the PS layer for the three-track new construction terrace, with four bunker wagons, one for PSS material and three for Gravel in front of which PSS pavers are operated. A conveyor extends from the bunker wagon for PSS material to the PSS paver, and a conveyor extends from each of the three bunker wagons for ballast to one of the ballast bed pavers. Of course, the alternative working constellations with regard to the number of pavers and bunker wagons or the number of installation devices described above in connection with a double-track new construction terrace are also conceivable and covered by the scope of protection. The same applies to four or more track new construction terraces.

In principle, it is provided according to the invention that the individual device components are electronically linked, so that the individual work processes are automated and linked. The paver can also be fully automated with electronic Surveying and leveling devices are linked so that heights and lateral positions of the layers can be controlled mechanically / electronically / via GPS, 13 and 14 show a guide cord 40a and probes 40b of the pavers 20, 30 as a measuring and leveling device. The guide cord 40a, which can be designed as a wire cord, is stretched at the side edge along the projected new construction route at a previously measured height and is used during the process as a tactile lead for the pavers 20, 30. The paving machines 20, 30 continuously tap the measure there during the forward movement. The guide cord 40a specifies the baseline (height / lateral position) of the layer to be installed. In Fig. 13 The layers 2, 3 to be installed are shown in dashed lines, the guide cord 40a, which extends perpendicular to the plane of the drawing, being understood only as an example with respect to the height shown, which corresponds here to the surface level of the ballast layer 3 to be installed. Depending on the forward movement (route length), the installation parameters of the respective layer profile, i.e. inclination, height, width and the like, which was previously electronically stored in the paver's control device based on the plan documents, are determined automatically, ie automatically, by the paver's control device . Alternatively, however, a manual control of inclination, strength, width and the like can be carried out by a paver driver on the guide line.

The intended profile of the respective layer, which depends on the projected new building terrace and parameters such as B. layer thickness, layer inclination and layer width can be set by the paver in manual and / or automatic control mode. In the manual control mode, the paving machine of the respective paver is set manually according to the intended profile. In the automatic control mode, the respective installation device is set by signals from a control device in which the parameters of the respective profile are stored.

Examples of further embodiments are in Fig. 8a , b to Fig. 11a , b shown. in 8a, b and 9a, b the PSS paver 20 has an additional leveling or compacting device, namely the compacting bar 24; in 10a, b and Fig. 11a , B shows the PSS paver 20, the compaction bar 24 and the ballast bed paver 30 also has a leveling or compacting device, namely also a compaction bar 34, in order to level and compact the installed PSS 2 or ballast layer 3, respectively.

The additional leveling and / or compacting devices 24, 34 are shown schematically here and arranged behind the respective installation device 22, 32.

As in Fig. 10b and 11b can be seen, the compression bar 24 of the PSS paver 20 extends over the entire width of the installed PSS 2 in order to level and compact it in the corresponding predetermined profile. The width of the compacting beam 34 of a ballast bed paver 30 corresponds to the width of the respective ballast bed or the respective ballast layer 3, that is to say, in the example shown, the double-track new construction route half of the total width. In contrast to the illustration, the width of the gravel layer can also be less than half the total width of the new double-track terrace.
