The ballast is sorted according to its characteristics and/or processing and/or separation of at least one rejected fraction. The material is passed to a second stage (350) where it is washed and especially for washing out fine granular material and/or the separation of clay, and then stored for laying at the permanent way working site.

Description

The invention relates to a method for providing bulk material paving material or bulk material paving materials along a line progressing construction site (hereinafter referred to as line construction site), in which at least one bulk material serving as paving material along the Line is transported and at least one treatment arrangement (hereinafter referred to as the first treatment order) that happens Bulk material of at least one treatment (hereinafter the first treatment called), which classifies and / or fractionates at least one bulk property or / and processing or / and Separate at least one bulk residue fraction or / and at least of a non-bulk residue material.

Such a method is, for example, a track treatment method, especially formation improvement processes and / or ballast cleaning processes, known, excavated on the old ballast of an existing track and is reprocessed for reinstallation. For example it is known, the method using a so-called formation improvement machine with integrated material recycling, for example of the RPM 2002 type from Plasser & Theurer.

In a German patent application filed on April 23, 2001 with the Title "Process for supplying a line construction site with building materials and associated transport or conveyor chain, as well as usable here Classifying and fractionating device ", official file number 101 19 777.2, the applicant also proposed, at a line construction site, e.g. track construction site, required materials (e.g. PSS / FSS material and ballast) to be delivered in a pre-mixed state and then assigned to the construction site according to at least one bulk property, if necessary, classify grain sizes or grain size ranges and - according to the classification - to fractionate the classification to provide corresponding bulk material fractions in association with the construction site. For example, gravel / sand material and gravel are mixed in non-sorted, possibly delivered in a more or less mixed state and then separated by seven.

After excavating an existing track bed and refurbishing treatment of this material by sieving, etc. (i.e. separation from Dirt, abrasion and other components including re-breaking of the ballast), fine particles remain on the individual after sieving Gravel stones that are not separated or loosened by sieving can, especially if the removed ballast through Clay is contaminated. A similar problem occurs with the one addressed Delivery of premixed materials (such as PSS / FSS material and Gravel), as for example sandy fine constituents of the gravel cling that are undesirable per se and for example in their total amount the customer's technical delivery conditions to be observed disagree for gravel.

It was recognized that these problems can be solved by that for processing the ballast or for separating the ballast plants used from the mixture material (sieve and crusher plants a gravel washing system is connected downstream, that detaches, separates and separates the fine components mentioned with any remaining residues. As Siebund Crusher plants are preferably screening machines in this context (for example single or double decker) and crusher systems with compared to conventional systems with higher performance and greater efficiency used. The washing plant can be used as a screening plant with high pressure washing nozzles, if necessary with upstream washing centrifuges or the like, be executed.

Regarding the ballast processing of old ballast, it was recognized that those occurring in track sections with high clay content in the ballast, in connection with the track bed cleaning or formation improvement Problems not solved so far by providing a clay separation plant can be mastered. The problem is that the Clay rolled into ball-like balls on the screening plants used and then not be eliminated from the following plants can. In particular, screening plants are not suitable for such loam bolls reliable removal, since the clay bulbs are the size of the gravel can have. It was recognized that it is possible to have one Clay excretion plant to be designed so that they Can remove lump of clay from the gravel, so that again processed ballast a ballast quality can be achieved that is far above the previously achieved standards for cleaned ballast and sometimes even reach the quality of new ballast.

The invention is based on the findings mentioned Process for the provision of bulk material or bulk material at a construction site progressing along a line (in Hereinafter referred to as the line construction site), in which at least one as Bulk material used for the installation material is transported along the line and at least one first treatment arrangement that happens Bulk undergoes at least a first treatment that classifies or / and fractionation according to at least one bulk property or / and processing or / and separating at least one bulk residue fraction or / and at least one non-bulk residue material comprises, and then at least a second treatment arrangement happens to the bulk material at least one second treatment undergoes a washing of the bulk material, in particular a washing off of fine constituents of the bulk material of grains of the bulk material, or / and subjecting the bulk material to a clay excretion treatment includes, and then - if necessary after a temporary storage - is provided for installation at the line construction site.

In the case of the reprocessing of excavated old ballast, it will Bulk goods preferably as part of the second treatment Undergo clay excretion treatment and then washed or washed. The bulk material can be in the second treatment arrangement pass at least one spiked roller to remove the clay Separate clay bulbs from bulk material.

As already indicated, the process can pick up old bulk material or include old bulk materials at the line construction site, wherein the old bulk material or at least one bulk material Waste bulk materials along the line of the first treatment arrangement supplied and subjected to the first treatment by this and then fed to the second treatment arrangement and through this the undergoes second treatment to be processed as bulk bulk paving material to be provided. It will be in this context in particular thought that the bulk material at least one Screening treatment and at least one crusher treatment by the first treatment arrangement and at least one washing or washing-up treatment undergone by the second treatment arrangement becomes.

• Verladen, nacheinander oder gleichzeitig, jeweiliger Schüttgutmengen einer Mehrzahl verschiedenartiger Schüttgüter,
• Transportieren, nacheinander oder gleichzeitig, der verladenen Schüttgutmengen in Richtung zur Linienbaustelle entlang der Linie zur ersten Behandlungsanordnung,
• vermittels der ersten Behandlungsanordnung: Klassifizieren und - entsprechend der Klassifizierung - Fraktionieren der herantransportierten Schüttgutmengen nach wenigstens einer Schüttguteigenschaft, ggf. Korngrößen oder Körngrößenbereiche,
• Bereitstellen und ggf. Zwischenspeichern von der Klassifizierung entsprechenden Schüttgutfraktionen in Zuordnung zu der Linienbaustelle, wobei wenigstens eine Schüttgutfraktion zuerst der zweiten Behandlungsanordnung zugeführt und durch diese zumindest einer Wasch- oder Abwaschbehandlung unterzogen wird und danach in Zuordnung zu der Linienbaustelle bereitgestellt wird.

Furthermore, it has already been indicated that the method can include supplying the line construction site with new paving materials in the form of different types of bulk materials which are required at the construction site simultaneously and / or in succession. In this context, particular consideration is given to the fact that at least one bulk material of the new building materials is fed to the first treatment arrangement and is subjected to the first treatment by this and then to the second treatment arrangement and is subjected to the second treatment. The line construction site can be supplied with new installation materials in accordance with the teaching of the above-mentioned German patent application No. 101 19 777.2 from April 23, 2001 or a European subsequent application, the disclosure of which is fully incorporated into the disclosure of the present application by reference. Reference is made to the corresponding European subsequent application filed at the same time as the present application with the title "Process for supplying a line construction site with construction materials and the associated transport or conveyor chain, as well as the classification and fractionation device that can be used here". In particular, the following steps can be carried out to supply the line construction site with new building materials:

• Loading, one after the other or simultaneously, the respective bulk quantities of a plurality of different types of bulk goods,
• Transporting, in succession or at the same time, the loaded bulk goods in the direction of the line construction site along the line to the first treatment arrangement,
• by means of the first treatment arrangement: classification and - according to the classification - fractionation of the quantities of bulk material transported according to at least one bulk material property, possibly grain sizes or grain size ranges,
• Provide and, if necessary, temporarily store the bulk material fractions corresponding to the classification in association with the line construction site, wherein at least one bulk material fraction is first fed to the second treatment arrangement and is subjected to at least one washing or washing-up treatment by this and then provided in association with the line construction site.

Wash water used for the second treatment can be reprocessed or / and for moistening debris or / and paving material be used. By reprocessing water the Water consumption is reduced and it can be used without a constant supply of water New water to be worked. Would you like paving material in front of the Moisten the installation to achieve a desired material consistency (In this context, it is particularly important for track foundation material thought), so it is useful to have used washing water, the possibly not cleaned or only slightly cleaned, to moisten the To use paving material. If necessary, can also be related sludge accumulated with washing or clay excretion be disposed of by adding it to the paving material. The Moistening of waste material could help avoid dust reduction be appropriate. Wash water already used for washing can then be used to moisten the waste material while it is still dirty be used as the waste material is disposed of anyway is so that additional dirt components are irrelevant. Mud associated with washing can also expediently disposed of by adding it to the clearing material becomes.

From the above it was already clear that regarding the line construction site in particular a track construction site is being considered, and the ballast undergoes the first and second treatment. But it is not excluded that the line construction site is a road construction site acts as a line in this context, for example Lane of a multi-lane road or the road itself is viewed. It in this regard, reference is made to the German patent application 101 19 777.2 referenced.

The method according to the invention can relate to a track construction site advantageous when using a track-accessible track treatment train performed by the first and second treatment arrangements having. For this purpose, the track treatment train can have at least one having the first or / and the second treatment arrangement Include treatment trolleys.

In a further development, it is proposed that ballast or a ballast should be comprehensive Bulk mixture subjected to the first and second treatment with the ballast as part of the second treatment first a first washing arrangement happens in which the ballast under the influence of centrifugal force Wash water is exposed and / or a high pressure spray exposed to wash water and then a second Washing arrangement happens in the ballast on a washing screen high pressure wash water jets is exposed. Here, the ballast in the showering arrangement fall through a spray zone, in which several, preferably rotating high-pressure water jets on the Apply gravel. This allows a particularly intensive showering the ballast with water, for example with operating pressures can be worked from about 40 to about 80 bar. In this Context it is preferred that the high pressure wash water jets are emitted by at least one rotating nozzle arrangement, preferably a rotating nozzle arrangement below the spray zone is arranged and rotating high pressure wash water jets directed upwards.

Regarding the second washing arrangement, further development is proposed that the washing filter moves to convey and turn the gravel grains and that high pressure wash water jets both from above and also aimed from below at the ballast on the sieve become. In this regard, may be lower, but still high pressures, for example at an operating pressure from 3 to 5 bar.

The two-stage ballast wash treatment given here is particularly advantageous in that the first washing arrangement is a enables effective pre-cleaning of the ballast, so that the total water consumption is reduced. If the ballast is less polluted, the ballast can bypass the first washing arrangement to be led past. Especially to remove sandy ones Fine components when delivering gravel in a gravel / sand material mixed state it will often be sufficient if the Gravel only passes the second wash arrangement. Furthermore, it shouldn't excluded that in some situations treatment of the Gravel is only sufficient with the first washing arrangement. Generally it is therefore proposed that the ballast be used as part of the second treatment the first and / or the second washing arrangement happens.

It is generally suggested that crushed stone or a mixture of crushed stone and another bulk material, possibly PSS material, in particular gravel, the is subjected to the first treatment, the ballast or the mixture in the first treatment of at least one screening according to at least one is subjected to a sieve curve to separate the ballast from the other Bulk goods - if available - to separate, and that the ballast afterwards undergoes the second treatment. It will be in this context especially to the delivery of crushed stone with other material mixed state according to the teaching of German patent application no. 101 19 777.2 thought.

Alternatively or additionally, old ballast can be excavated at the track construction site undergo the first and second treatments, wherein the ballast at least once during the first treatment Sieving according to at least one sieve characteristic and at least once is subjected to a crusher treatment. In this way, a effective processing of the excavated ballast can be achieved.

The crusher treatment is used in particular to restore the ballast to make it sharp-edged.

In connection with the reprocessing of the old ballast, the Crushed stone as required or as part of the second treatment undergo the clay excretion treatment. This happens the ballast preferably at least in the second treatment arrangement a spiked roller to separate clay balls from the gravel.

Unwanted and possibly hazardous dust emissions to avoid the gravel before or / and during excavation be moistened by spraying with water. So it can be before Picking up the ballast from the water track sprayed onto the old ballast or during the recording, for example in an excavation chain, Water is sprayed onto the gravel to reduce dust to avoid or at least to reduce. Such dampening the ballast previously stood in the way of a dampening of ballast inevitably leads to foreign matter contaminating the ballast (for example soil material, such as clay) comparatively adhere firmly to the ballast and by a conventional procedure cannot be removed from the gravel. The invention intended washing treatment of the ballast can be adherent But remove portions reliably, so that to a certain extent only the invention Washing treatment the moistening of the ballast to avoid dust makes possible. A major advantage is achieved namely a significantly reduced or even largely avoided generation of dust during ballast cleaning, etc., which reduces the visibility and pollution of the environment and health of the personnel avoided or be greatly reduced, especially in the case of in a tunnel running track sections.

The clay excretion treatment or / and that are preferred Spray the ballast with water as part of one of these steps provided overall procedure only if necessary. Further can provide the first and the second treatment in the context of a Overall, the first and second treatment of the excavated Gravel should be omitted on a case-by-case basis if the ballast is too strong is dirty. In this case, the ballast is disposed of, if necessary together with excavated base material.

The method according to the invention can be part of a formation improvement method be carried out in which the ballast bed and the Substructure of a track and the substructure using substructure material and using the ballast bed of new ballast and / or recycled old ballast be rebuilt.

Furthermore, the method according to the invention can be part of a ballast cleaning or / and renewal process are carried out, in which the Ballast bed of a track is excavated and the ballast bed using new ballast and / or recycled old ballast is rebuilt while the existing track substructure remains.

The invention also provides a track treatment train for performing the method according to the invention ready. The track treatment train according to the invention comprises at least one track-mounted ballast washing device or / and at least one track-passing clay separation device. Regarding the ballast washing device is on the train according to the invention ballast soiled by means of at least one conveyor arrangement Ballast washer feedable and from the ballast washer crushed stone subjected to at least one washing or washing-up treatment dischargeable. Regarding the clay separation device is according to the invention on the train by means of at least one conveyor arrangement with clay contaminated ballast of the clay separation device, in particular containing clay bulbs feedable and from the clay separation device subjected to at least one clay excretion treatment Ballast can be removed.

The track treatment train can have at least one trackable classification and fractionation device having an input area and has several output areas and which has at least one property, if necessary grain size or grain size ranges, one in the input area entered bulk goods and the bulk goods entered classified according to the at least one property and - according to the Classification - fractionated to give bulk fractions corresponding to the classification to be delivered to the delivery areas, a gravel bulk fraction from an output area assigned to this fraction can be fed to the ballast washing device by means of a conveyor arrangement.

It is further proposed that the classifying and fractionating device comprises at least one sieve arrangement designed for this is, according to at least one sieve characteristic, bulk material at least one Undergo screening and - depending on the composition of the bulk material in the Regarding the sieve characteristic - the bulk material in at least one, regularly to transfer at least two bulk fractions, one of which Ballast bulk fraction by means of the conveyor arrangement of the ballast washing device is feedable.

The track treatment train can also be at least one rail-accessible Ballast excavation device for lifting the ballast bed of a track have, being on the train by means of at least one conveyor arrangement excavated ballast from the ballast excavation device of the ballast washing device can be fed and from the ballast washing device crushed stone subjected to at least one washing or washing-up treatment is dissipatable. The track treatment train can also be a rail-accessible one Ballast processing device for processing excavated material Have gravel, being on the train by means of at least one conveyor arrangement excavated ballast from the ballast excavation device first of the ballast processing facility and of this processed Ballast can be fed to the ballast washing device and from the ballast washing device at least one washing or washing-up treatment subjected gravel is removable.

In addition to at least one ballast excavation device, the track treatment train can furthermore have at least one substructure excavation device, for a particularly high excavation capacity when cleaning ballast can preferably also be used as a ballast excavation device.

As already mentioned, the track treatment train can be a rail-compatible one Clay excretion device, depending on the expediency also in the ballast washing facility or the ballast processing facility could be integrated. The clay excretion device is In particular, it is intended to remove clay bulbs from the excavated and If necessary, prepared ballast before the ballast washing device is supplied excrete.

The clay separation device can have at least one spiked roller have, which - possibly in cooperation with at least one assigned Elastic roller (such as rubber roller or foam rubber roller) - clay balls can separate from the gravel.

With a view to avoiding or reducing dust in the In connection with the excavation of old ballast, it is advantageous if the track treatment train a ballast moistening device for Moisten the ballast of a ballast bed before lifting it out the ballast excavation device and / or excavated for moistening Having ballast in or / and after the ballast excavation device. The Ballast moistening device can be equipped with at least one water spray arrangement be executed.

The track treatment train can advantageously also at least one of the ballast washing device or / and assigned to the ballast moistening device Have water reservoir so that the track treatment train can be used without permanent water supply. To already Washing used washing water again for washing or for others To be able to use purposes, the track treatment train preferably has a water treatment device assigned to the ballast washing device on.

Regarding the ballast washing device is particularly preferred proposed that it have at least one first washing arrangement, in which the ballast can be put on washing water under the influence of centrifugal force is and / or a high pressure shower with wash water is, and / or has at least one second washing arrangement, in the crushed stone on a washing screen high pressure washing water jets is vulnerable. The first washing arrangement can advantageously be a gravel drop section which includes a spray zone in which the ballast several, preferably rotating high pressure wash water jets is vulnerable. For this purpose, the first washing arrangement can have at least one have rotating nozzle arrangement. Preferably a rotating one Nozzle arrangement arranged below the shower area and therefore suitable to point rotating high pressure wash water jets upwards.

The washing screen of the second washing arrangement is preferably for conveying and turning the gravel is movable, and it is preferred High pressure wash water jets from both above and below the gravel on the sieve can be straightened.

As a rule, the track treatment train becomes at least a rail-compatible one Ballast installation device for installing ballast in the track bed a track or to build a track bed from gravel. In a further development it is proposed that on the train by means of at least a conveyor arrangement of at least one washing or washing-up treatment subjected gravel from the ballast washing device and the Ballast installation device can be fed.

Furthermore, the track treatment train usually becomes at least one substructure installation / superstructure device exhibit.

As already mentioned, the line construction site is not mandatory for a track construction site, but also for example one Road construction site. Furthermore, it can also be advantageous for track construction work assigned to the track construction work, in particular providing installation materials Systems not rail-bound, but road-bound perform. The invention accordingly relates generally to a rail-accessible or street-going material washing device that one Has input area and an output areas and designed for it is at least bulk material material entered in the input area undergo a washing or washing-up treatment and at the dispensing area provide. The material washing device can be at least one first washing arrangement, in the bulk material under centrifugal force Wash water can be put on and / or with a high pressure shower Wash water can be put on, and / or at least a second washing arrangement have in the bulk material on a washing screen High pressure wash water jets can be exposed. The first washing arrangement can have a bulk material drop section that has a spray zone comprises, in which the bulk material several, preferably rotating high pressure wash water jets is vulnerable. For this purpose, the first washing arrangement have at least one rotating nozzle arrangement. Preferably is a rotating nozzle arrangement below the spray zone arranged and suitable for rotating high pressure wash water jets to point upwards. The washing sieve of the second washing arrangement is preferably used for conveying and turning the bulk material grains movable, and it is preferably high-pressure wash water jets both from above and from below onto the one on the sieve Bulk material can be straightened.

The material washing device can advantageously have at least one water reservoir or / and have a water treatment system.

The invention further relates to a rail or street Clay excrement device, which has an input area and a Has output area and is designed in the input area entered bulk material at least one clay excretion treatment to undergo and provide at the output area. Preferably the clay excretion device is designed for clay bolls to separate from the bulk material. For this purpose the clay separation device have a spiked roller, which - if necessary in cooperation with at least one assigned elastic roller (possibly rubber roller or foam rubber roller) - Separate the loam from the bulk material can.

The material washing device or the clay separation device is preferably designed for crushed stone bulk material, especially of ballast material suitable for track bedding.

According to the above, the invention provides, among other things, an independent, Track or road mobile ballast cleaning work module ready. The track-traveling work driving module can be advantageous in a so-called Formation improvement machine for ballast recovery or / and Material separation for the supply of new materials as well as for a track-driven one Ballast cleaning machine can be used for ballast cleaning.

According to the above, special, optimally acting components are used for this are proposed and suggestions are made according to the above for an advantageous arrangement of the components or the work module made in the workflow or along the material flow.

Regarding the washing treatment in connection with a gravel reprocessing is preferably pre-cleaned and in a crusher broken gravel in a downstream screening plant washed, for example, a system of high pressure spray nozzles has, which are arranged such that the arranged on a sieve Gravel from all sides captured by spray water and from the adherent Remaining components is exempt. This washing filter can, for example a high pressure washing centrifuge upstream, the special Contamination of the ballast can be used for pre-cleaning, to reduce water consumption.

Since neither rolled up over a screening plant nor through a washing plant Clay bales can be excreted in the car wash a so-called clay excretion toner upstream of this Clay parts are removed from the gravel and fed into the overburden. Preferably Both the washing centrifuge and the clay toner are required can be switched on so that it is at a lower or normal degree of contamination of the track ballast can be bypassed.

The screening plant can be designed as a two- or multi-deck screen. On Basis of various sieve coverings (e.g. for example Finger sieve) can have higher throughput and better cleaning performance be achieved than with conventional, related Screening machines used with the ballast processing possible was. The screening plant can advantageously be designed so that at very high degree of contamination only one gravel grain in the others Machining cycle is brought while the rest of the ballast material is fed into the overburden. With a particularly high degree of contamination the entire excavated gravel can also be fed into the overburden become.

The cleaned ballast can be used in the work cycle of a planning improvement machine or ballast cleaning machine are fed and this reduces the supply of new ballast (supplementary ballast). Preferably the entire workflow takes place within a track-drivable Investment.

The track-traveling system is preferably designed for that Sufficient water must be carried in the wash cycle. Preferably, the water in the relevant track-driven working module carried and continuously supplemented by the washing process and the Treatment lost amount of water. As far as possible is a water cycle provided in the soiled by the washing process Water is treated via a treatment plant, for example the coarse or fine dirt particles via a settling plant / flocculation plant withdrawn from the water, so that the recovered water to the further work process can be fed again. The cleaning can advantageously be carried out in several clarification stages. The water with the The highest degree of cleaning is added to the wash system wash circuit reused by fresh water. Still with fine ingredients Contaminated water can be beneficial for increasing the level of moisture from the installation material (such as PSS / FSS material) or for moistening the track bed in the area of the excavation device (possibly one or more Excavation chains) are used.

Remaining sludge can be added to the excavated residues and disposed of become. You could also think of the mud Mix PSS / FSS material, which may be appropriate Approval would be required.

According to the invention, a very high quality of ballast can be achieved with which in particular no clumps of clay in the gravel after cleaning are included. It is a great throughput when processing crushed stone possible, while the water consumption can be kept low.

In connection with the implementation of an inventive Comprehensive overall procedures can be used in the case of track construction work advantageous from the patents DE 32 19 025 C2 and EP 0 096 236 B2 known conveyor and silo wagons are used. The The content of these patents is incorporated by reference into the disclosure included in the present application. It can also be advantageous Transport and silo wagons are used, which are in an am German patent application filed by the applicant on April 12, 2001 the title "Rail-accessible conveyor and silo wagon, transport train and Procedures for collecting, storing and delivering materials in connection with track construction work ", official file number 101 18 393.3 or a European subsequent application for this are. The content of this German patent application or the European one Late filing is also made by reference in the disclosure of present application included. At the same time as the present The corresponding European subsequent application filed with the title "Rail-accessible conveyor and silo wagon, transport train and methods for recording, storing and delivering Materials related to track construction work "is referenced.

The invention further relates to a method for processing used bulk material, if necessary as part of the implementation of the above inventive method. In the procedure proposed here it is provided according to the invention that the old bulk material at least is subjected to a fractionation treatment by which Old bulk material at least one bulk fraction of a grain size range smaller grain sizes and at least one bulk fraction Grain size range of larger grain sizes is obtained, if necessary with separation at least one residue fraction, and that then the bulk fraction the grain size range of larger grain sizes at least one Is subjected to crusher treatment, possibly with removal of a residue fraction, and that then the one subjected to the crusher treatment Bulk fraction of the grain size range of larger grain sizes and the Bulk fraction of the grain size range not subjected to crusher treatment small grain sizes to at least one bulk fraction Grain size range of smaller and larger grain sizes merged becomes.

The conventional method for stationary processing of used ballast is whole crushed stone subjected to a crusher treatment to get a sharp edged Restore gravel condition. It has now been recognized that a higher performance of a crusher used, a better one Adjustment possibility for the crusher device, less wear or a longer service life for the crusher device and a total of one higher yield in ballast recovery can be achieved if the Ballast (in general: the bulk material) only from a given Grain, i.e. only one gravel fraction (generally: bulk fraction) one Grain size range of larger grain sizes subjected to crusher treatment becomes. Since the ballast fraction (generally bulk material fraction) of the Grain size range of smaller grain sizes not the crusher treatment is subjected to the smaller grit by the crusher treatment not destroyed, but remains intact and can be used by those who have broken down Fraction are fed again. So there are no losses the gravel or bulk fraction of the grain size range is smaller Grain sizes. On the other hand, the crusher device due to Non-supply of the ballast or bulk material fraction of the grain size range smaller grain sizes better on the supplied, crushed gravel or bulk fraction of the grain size range of larger grain sizes be adjusted or adjusted, which on the one hand improves crushing results and on the other hand less wear for the crusher result.

As a rule, the two bulk solids fractions are brought together (in the application considered primarily: gravel fractions) the resulting bulk fraction (gravel fraction, if applicable) of the grain size range smaller and larger grain sizes of at least one separation treatment undergo at least one residue fraction to separate, to further improve the quality of the recycled bulk goods. In particular, this means that the chips or chips split during the breaking process loosened parts and, for example, other residues Disposal supplied.

At least for bulk goods or crushed stone with normal or stronger ones Degree of pollution is to achieve high material quality advisable, the merged bulk fraction of the grain size range smaller and larger grain sizes of at least one washing treatment to undergo, preferably after the separation treatment (insofar as this is provided). The result is already in the context above advantages explained with the first method according to the invention. The combined bulk fraction can be used before the washing treatment the grain size range of smaller and larger grain sizes advantageous undergo a clay excretion treatment. It also does not appear to be completely ruled out that old bulk material even before the fractionation treatment of a clay excretion treatment to undergo. However, only the bulk fraction is particularly preferred the grain size range of larger grain sizes of clay excretion treatment to undergo, preferably before the crusher treatment, so that the crushing device is not loaded with the clay.

A clay excretion treatment for the bulk fraction of the grain size range smaller grain sizes will usually not be necessary since the clay is usually quite large as a result of the fractionation treatment Lumps or loam of clay forms in the fraction of larger grain sizes are included.

The method is preferably used for the treatment of old ballast, that as waste bulk material of the at least one fractionation treatment is subjected to the from the old gravel at least one bulk fraction, namely at least one crushed stone fraction, the grain size range of smaller grain sizes and at least one Bulk fraction, namely at least one crushed stone fraction, of the grain size range larger grain sizes is obtained.

It is proposed as particularly preferred that the method for Provision of bulk material paving material along a line progressing construction site (hereinafter referred to as line construction site) serves and that the old bulk material and the bulk fractions can be transported along the line. At the line construction site it can be act as a track construction site. The method can then be used of a track-accessible track treatment train, which Has facilities for performing the method steps.

Fractionation treatment will be advantageous on a regular basis or / and to carry out the separation treatment as a screening treatment, preferably at least one multi-decker screening device, possibly Two-decker screening device is used.

As part of the overall process, it is not imperative that the crusher treatment or / and the separation treatment or / and the clay excretion treatment or / and the washing treatment is always carried out become. These treatments can vary depending on the quality of the Old bulk material (possibly old ballast) can be left out.

The method according to the invention can be part of the above process according to the invention are carried out, the fractionation treatment, the crusher treatment (where provided) and the Separation treatment (where provided) as the first treatment and the Washing treatment (where provided) and clay excretion treatment (if provided) should be identified as a second treatment.

For both processes, it is proposed that the preparation of im Water used in the process, possibly washing water, includes. During the treatment of the water, at least one can advantageously be used Slanted clarifiers are used, the sloping from top to bottom Has tubes in a pool of water, those with a flocculant displaced dirty water is supplied, whereby flocculated Material removed in the area of a bottom of the water basin and clarified water in an upper area of the pool is subtracted.

The water treatment can then be carried out particularly reliably be, if at least one water treatment unit, possibly the Inclined clarifier, for performing the water treatment in a target horizontal position is brought or held in this target horizontal position becomes. This suggestion is important even if one is for water treatment used processing unit itself in one oblique position works. Changes are always problematic the current position of the water treatment unit, the lead to a back and forth sloshing of water contained therein could. Such changes are in mobile water treatment units, which, for example, is part of a rail-bound or street-going Wagens are to be expected, especially if the water treatment unit (or the wagon) according to progress a line construction site is carried along the line, as preferred is. So in the case of a track construction site by adjusting the water treatment unit relative to a carriage frame in the desired horizontal position one at a current track position of the track-running carriage existing track cant be compensated for the water treatment to be able to perform reliably. In particular, how implicit already mentioned, a back and forth sloshing of water in the unit reliable in the transverse direction of the train due to changing track cant be prevented.

As part of the training proposal, you can also provide through Adjusting the water treatment unit relative to a / the car frame in the desired horizontal position at a current track position of the track-going wagon or a slope there Compensate track slopes to ensure reliable water treatment to be able to perform. In particular, this is the back and forth Sloshing of water in the unit in the longitudinal direction is prevented.

In another aspect, the invention provides a track treatment train ready to carry out the method according to the invention, which may Features of the track treatment train according to the invention already treated above having. It is proposed that the track treatment train comprises: at least one track-running fractionation device, the old bulk material feedable and from the at least one bulk fraction a grain size range of smaller grain sizes and at least one Bulk fraction of a grain size range of larger grain sizes as well if necessary, at least one residue fraction can be removed, as well as comprehensive at least one track-running crusher device, the bulk material fraction of the grain size range of larger grain sizes can be supplied and at least a bulk fraction subjected to at least one crusher treatment and if necessary at least one residue fraction can be removed, as well as comprising at least one train-bound conveyor, by means of the respective material or fraction of the facilities mentioned can be supplied or removed from these, the bulk fraction the grain size range of smaller grain sizes and at least bulk fraction subjected to crusher treatment with mediation the conveyor to at least one bulk fraction of a grain size range smaller and larger grain sizes can be merged.

The track treatment train can have a track-separating device, the merged bulk fraction by means of the conveyor the grain size range of smaller and larger grain sizes can be fed and at least one of them by means of the conveyor Bulk material useful function and at least one residue fraction can be removed is.

The track treatment train advantageously has a track-running washing device on, by means of the conveyor the bulk material useful fraction feedable and at least one of them by means of the conveyor washed bulk material useful fraction is removable, possibly to a track-bound Built-in device or a place of installation. It is further preferred that the track treatment train is a track-passing clay separation device has that between the fractionator and the crusher or switched in front of the washing device or is switchable. The conveyor device is preferably designed to be dependent on the degree of contamination of the bulk material, in particular ballast, either the relevant bulk or crushed stone fraction of the clay separation device fed and discharged from this or is guided past the clay separation facility. The conveyor can also be designed, optionally the bulk material useful fraction past the washing device directly to the built-in device or Install the installation site.

It can also be provided that the conveyor device is designed to the bulk fraction of the grain size range of larger grain sizes optionally past the crusher device directly with the bulk material fraction of the To bring together the grain size range of smaller grain sizes. Usually you will not be able to do without the crusher treatment or want.

The invention also provides a rail or road version Cart with at least one water treatment unit (for example a slanted clarifier). It is suggested that between one Carriage frame and the unit or one that carries the unit Support arrangement an adjusting or compensating device is effective, by means of the water treatment unit relative to the car frame in a target horizontal position adjustable or in this target horizontal position is durable. The rail or street car (the one in the case training as a rail-accessible car as part of the track treatment train ) can be used to carry out the method mentioned above serve with regard to water treatment.

The adjusting device can have at least one hydraulic actuating cylinder to actively maintain or set the desired horizontal position. In this context, the carriage can advantageously have a sensor device have an actual position of the unit or the support arrangement recorded relative to the target horizontal position. The setting device is then preferably depending on at least one task of Sensor device operable. In particular, it is thought that a Control rice for setting or holding the target horizontal position is formed.

A particularly preferred embodiment is characterized in that the adjustment or compensation device a gimbal for the unit or the support arrangement comprises. In the event that an active Gimbal has the advantage of that only small actuating forces are required. But you can also on a do not actively set or maintain the desired horizontal position and only on setting and holding this position due to Set the effect of gravity. This will be especially slow at relatively advancing track construction sites are sufficient. In this context could be from a "passive" setting and holding the target horizontal position speak.

1 shows a railway wagon designed as a conveyor and silo wagon 10, a given in terms of its cross-sectional dimensions Limit profile 12 is sufficient. The wagon 10 has a vehicle frame 14 Wagon side walls 16 on. The wagon frame 14 is in itself known manner on a plurality of bogies 18 each stored with several wheel axles.

In a lower wagon area 20 there are low-floor units Various drive devices for those to be described below Material conveyor, storage and handover facilities arranged.

A material receiving trough 24 is located above the lower wagon area held stationary in the vehicle frame 14, which has a floor 26 and side walls 28 and together with one of the side walls 28 section 30 of the side walls 16 adjoining the top has a receiving box forms for bulk material. A bulk level is an example indicated by the dashed line 32.

The bottom 26 of the receptacle has in a manner known per se and Way an upper run of an endless conveyor belt, for example a scale belt, by means of which the received in the receiving box 40 Material can be conveyed in the longitudinal direction of the wagon.

Above the receiving box 40, which is also referred to below as the “lower receiving box” is called, is another ("upper") recording box 42 arranged, which also has a receiving trough 44 with a bottom 46 and side walls 48. The upper receiving box 42 can also Pick up bulk material; a corresponding level is through dashed line 50 indicated as an example.

The bottom 46 of the upper receiving trough 44 points in a corresponding manner Way an upper run of a conveyor belt, for example a scale belt, on that for conveying the bulk goods in the longitudinal direction of the wagon serves.

The upper receptacle 44 is not stationary in the vehicle frame 14 arranged, but by an adjustment mechanism, not shown Hydraulic base adjustable in height. If you lower the upper receptacle 44 decreases so that it increases above the tub floor 46 for material storage available space with a corresponding reduction in the above the tray floor 26 of the lower receiving tray 24 for material storage available space and vice versa. By adjusting the height The upper storage trough can therefore be the material storage capacity of the upper and lower receiving boxes 40 and 42 can be adjusted in opposite directions to each other, which becomes a capacity increases and the other capacity is reduced.

It is assumed that in Fig. 1 regarding the upper receiving trough 44 whose uppermost position is shown in the vehicle frame 14. If you lower the receiving trough 44, bulk goods can go above the level of the upper edges of the tub side walls 48, because to the side of the side walls 48 wagon-stationary boundary walls 52 are provided, which are lower than in FIG. 1 adjustment positions the upper receptacle 44, the side walls 48 of the top so to speak extend and together with the tub sides 48 the receiving box 42 limit laterally.

The upper receptacle 44 together with a support for the tub Intermediate frame 54 adjusted in height. The lowest adjustment position of the upper receptacle 44 is through the upper edges of the side walls 28 of the lower trough 24 determined. The lower receiving box 40 is then essentially only laterally through the side walls 28 limited because a filling of the receiving box 40 above the level of upper edges of the side walls 28 in the lowest adjustment position of the Significant extent no longer possible in the upper receptacle is.

In Fig. 1 it can be seen that based on the limit profile 12 above of transverse stiffening elements 60 of the vehicle frame 14 is still space. In this area the upper end of a transfer and loading conveyor belt can be arranged for the material transfer or filling the upper receiving box 42 is used.

The conveying speed of the conveyor belt assigned to the tub floor 26 on the one hand and the conveyor belt assigned to the tub floor 46 on the other hand, they are variable and independently adjustable.

The conveyor belts can also be switched on and off independently of one another. As a rule, the belts with the same direction of conveyance operate. But it can be useful for some situations if opposite directions of conveyance are provided or are adjustable.

The receiving boxes and their conveyor belts can each be different from each other independently according to the teaching of the patent specifications DE 32 19 025 C2 and EP 0 096 236 B2 optionally for storing and conveying Materials, especially of different materials, are used become. It is also possible to use the one receiving box with its conveyor belt (which can also be designated together as a conveyor and silo belt) for material storage and the other storage box with his Conveyor belt (collectively also known as conveyor and silo belt) for Use material handling. The conveyor and silo belts can be used for parallel supply and simultaneous storage or parallel removal and simultaneous storage of materials and material fractions be used. For example, gravel and sand can be laid in parallel lead to a track construction site.

Fig. 2 shows a side view of a chain of conveyor and silo wagons of the type shown in FIG. 1. Wagons 10a, 10b and 10c can be seen, each a lower receiving box 40a or 40b or 40c and have an upper receiving box 42a or 42b and 42c. The Receiving boxes are transfer conveyors cantilevered over a wagon end 70 and 72 with each other in the sense of a transfer of bulk material connected from wagon to wagon in a conveying direction F, namely the lower receiving box 40a over the transfer conveyor 70a with the lower receiving box 40b and this over the Transfer conveyor 70b with the lower receiving box 40c, and the upper receiving box 42a via the transfer conveyor 42a with the upper one Receiving box 42b and the upper receiving box 42b over the Transfer conveyor 72b with the upper receiving box 42c. The transfer conveyor each extend from a lower material transfer level approximately at an angle according to the level of the respective tub floor upwards over the maximum possible fill level of the receiving boxes. The Transfer conveyors can each be on a material feed hopper or the like of the connected receiving box. The lower receptacle boxes are opposite the upper receptacle boxes slightly offset against the conveying direction F, so that an end region of the respective lower receiving box, which may be a material introduction funnel has, upwards not through the respective upper receiving box is covered and is thus accessible for the material supply.

The transfer conveyors are preferably in accordance with relevant track curve radii laterally swiveling, in order to be able to track material even in a track curve To be able to hand over wagons to wagons. Furthermore, the transfer conveyors preferably in a vertical plane at least to a certain extent Extendable to the extent of the material introduction funnels or receptacle edges of the wagon leading in the direction of conveyance F. to be able to take off. A winch or the like can be provided for this purpose his.

Fig. 3 shows a corresponding chain of conveyor and silo wagons 10a to 10f each with an upper and a lower receiving box. For the respective receiving box is the one received therein conveyed bulk material indicated. The trailing in the direction of conveyance F. shown wagon 10 'is in a front area in the conveying direction F as trained the conveyor and silo wagons and in particular has transfer conveyors of the type described. In a conveying direction F rear In this area, this wagon has material transfer hoppers and transfer conveyor belts on the material feed from each other via the transfer conveyor independently in the chain of the upper receiving boxes and in the Allow chain of lower storage boxes. The wagon 10 'can be Adapter or transfer wagons are called and allows for example the material supply from bucket of bucket transport wagons or from a conventional conveyor and silo wagon with only a receiving box, for example in accordance with the aforementioned patents DE 32 19 025 C2 and EP 0 096 236 B2 or from the proven Type MFS 40 (System Plasser - Knape) or successor types. According to one here particularly interesting application can be in the chains of Receiving boxes bulk material fractions are fed by a rail-accessible classification and fractionation device, possibly in the form of a Screening or screening device can be provided.

In the chain shown in FIG. 3, the wagon 10d is currently being emptied, by delivering material to the associated receiving boxes via its transfer conveyor of the wagon 10e leading in the conveying direction F is handed over becomes. The amount of material stored in the wagon 10e remains constant, since one of the supplied amount of material for each of the two receiving boxes appropriate amount of material on the transfer conveyor in the Receiving boxes of the wagon 10f is handed over. The recording boxes of this wagon do not store any significant quantities of material, since that emerging material is conveyed across the wagon in the direction of conveyance F. becomes.

The wagon 10c currently contains no material and also does not convey any material from wagon 10b to wagon 10d. Waggon 10b is currently over the wagon 10a, which is only used for conveyance, is filled with material which is supplied to the adapter wagon 10 '. Depending on which means of transport or classification and fractionation means the adapter wagon 10 'material or materials can be supplied, the receiving boxes of the wagon 10b simultaneously or in succession or alternately with Material to be filled, for example crushed stone and sand, from which Chain of wagons to be able to supply a track construction site.

Such a situation may arise at a later date result that the wagon 10d and the wagon 10e essentially are emptied. These wagons can then be from wagon 10b can be filled out again or the track construction site can immediately from the wagon 10b over the wagons 10e, 10d, 10e and 10f be supplied with materials. One can continuously load and Implement unloading cycle that is constantly sufficient for a sufficient material ensures that continuously the required materials of the track construction site can be supplied.

What has been said here applies here correspondingly to the removal of different materials from a track construction site. In this case it could the adapter wagon 10 ', for example from a track treatment facility forth with materials, for example two different excavation materials (such as ballast and substructure material). The conveying direction F can in both cases, that is, both for the material supply as well as for material removal, the working direction of a track treatment train or a track treatment facility (i.e. the direction of travel a walking track construction site).

Fig. 4 shows an example of a track treatment train as mentioned. 80 denotes a track treatment device moving in a working direction A, for example a so-called formation improvement machine, which has an excavation chain 82. Excavated material (here e.g. gravel and earth building materials or sub-construction material together) is conveyed to a conventional conveyor system via conveyor devices 84 Hand silo wagon 11, which is used for material removal and for example the conveying direction corresponding to the working direction A. F trailing wagons of a chain of similar conveyor wagons each with a receiving box. The material removal can accordingly the teaching of the patents DE 32 19 025 C2 and EP O 096 236 B2 done.

The track treatment device 80 is made up of two as intermediate stores serving conveyor and silo wagons 10a and 10b of the in FIGS. 1 to 3 shown type with two different materials or material fractions supplied as needed, namely via several intermediate wagons 90, 92 away, the elevated conveyor belts 94 and possibly one or more Have transfer chutes 96, for example for crushed stone material. The intermediate wagon 92 has one per se in the exemplary embodiment shown known stuffing device. The wagon 90 can be used as a carrier for drive devices, Motors, hydraulic pumps, generators, etc. are used.

The wagons 10a and 10b serving as temporary storage are over a trackable sieve or sieve device which can be designated as a sieve wagon (as a preferred embodiment of a classification and fractionation device) 200 with the materials required at the track construction site replenished. The materials are essentially arbitrary Order or in more or less highly homogeneous mixtures a feed hopper 202 fed to the screening trolley 200 and over suitable funding, in particular at least one conveyor belt, at least a separating sieve of the screening car. That in Fig. 4 by a sieve drum 204 symbolically represented represents a separating sieve separates the supplied materials according to at least one characteristic curve the separating screen in two fractions, for example a sand fraction and a crushed stone fraction, one of which is in the lower chain of storage boxes and the other in the top chain of storage boxes of the Wagons 10a and 10b via suitable conveyors and transfer conveyors is fed. Even if currently homogeneous or unmixed Material is fed to the feed hopper 202 this material is mandatory according to the embodiment shown here the separating sieve 204. As a result, the required materials achieved the greatest flexibility without being logistic Effort is required. As part of the cache capacity of the conveyor and silo wagons 10a and 10b, it doesn't matter which one Order or in what mixing ratios the individual materials required be transported, it is sufficient if the brought in Materials related to the cache capacity of the Wagons 10a and 10b roughly the material consumption ratio at the Track treatment device 80 correspond. Overall it is achieved that Large quantities of different materials are fed to the track construction site to be able to make appropriate construction progress (such as renewed track per hour).

To procure the materials, if necessary in separate and if necessary, mixed together, conventional conveyor and silo wagons 11a, 11b, 11c and 11d can be used. Another, in Fig. 5 shown possibility is to connect the two chains from each other Storage boxes for - if necessary - two different ones Materials or material fractions via the screening trolley 200 ' To supply container transport wagons 100a, 100b and 100c, each have a plurality of transport buckets 102. To empty the Buckets into a material feed hopper 202 or the like of the screening wagon 200 'can gantry cranes 104 in a manner known per se are used, at least one along the chain of Container transport wagons is movable. The buckets of the wagons can also be used be loaded with different materials, so that by means of a wagon or by means of a chain of wagons attached to each other at the same time different materials are fed to the track treatment train can. Another possibility is that there are several in each bucket different materials, possibly as a mixture, are transported here.

4, several conveying and silo wagons are used only one receiving box at a time, so these receiving boxes each filled with different materials, then after emptying for example the wagon 11c, which for example brings up gravel transported nat, which then, for example, via the screening car 200 hand over the lower chain of receiving boxes of wagons 10a and 10b was subsequently entered via wagon 11c from wagon 11b other material, such as sand, over the screening trolley 200 upper chain of receiving boxes of the wagons 10a and 10b fed becomes. Another possibility is that a single wagon, for example the wagon 11d, transported both gravel and sand which materials are then screened in the screening car 200 be separated from one another by means of the separating screen 204.

Regarding the transfer of materials into the chain of receiving boxes by means of the screening wagon 200 or 200 'according to FIGS. 4 and 5 to point out that the screening car is advantageous with several, here with two transfer belts 70 and 72 so material simultaneously in the upper chain of receiving boxes and in the To be able to feed the chain from the lower receptacle boxes.

It was mentioned above that, for example, in the upper chain of Gravel storage boxes and in the lower chain of storage boxes Sand (PSS material) is fed. Instead, it goes without saying also possible to put the ballast in the upper chain of storage boxes and at least feed the sand into the lower chain of receptacle boxes then when - this is preferred - the upper and lower receiving boxes each for the inclusion of all in connection with track construction work required materials are suitable.

The above in connection with conveyor and silo wagons with two stacking boxes and one for separation classification and functioning device designed by two fractions was explained, can be easily on conveyor and silo wagons with more than two receiving boxes, for example three receiving boxes, and one designed to separate more than two fractions Extrapolate classification and fractionation device. It can be done three or more different materials or material fractions from each other undivided (mixed if necessary) and according to requirements via a appropriate classification and fractionation device, if necessary screening device, lead to the track construction site. You can do it, for example think sand, crushed stone of a first grain and crushed stone of a second, different grain size from the first grain size, if necessary, simultaneously feed the classifying and fractionating device, which then provides appropriate material fractions. Other uses become the specialist familiar with track construction work without much thought come up immediately. The person skilled in the art will also immediately recognize that the Above explained on the basis of track construction work without further ado Construction work in connection with any other line construction site, for example a road construction site, is transferable.

6 shows an embodiment variant of the track treatment device 80 with two excavation chains 82a and 82b. The take-up chain 82b takes for example, the ballast bedding and the receiving chain 82a for example, the gravel substructure (such as earth building materials). The one from the Excavated chains are separated from each other via conveyors 84a or conveyors 84b in each case assigned receiving box 40g or 42g of a conveyor and silo wagon 10g passed, the one in the working direction or conveying direction A trailing wagon of a chain of wagons of the corresponding type is. The ballast thus fed into a chain of lower storage boxes and the substructure excavation thus supplied to a chain of upper receiving boxes can, for example, in a continuous loading and unloading cycle 3 are transported away from the track construction site. It is also possible to use the track treatment device 80 with a material preparation device equip or a separate material processing wagon, about between the rail treatment facility 80 and the chain of silo and conveyor wagons to provide for the excavation at least one of the conveyor chains by fractions or component materials to separate and / or recycle and so material or materials or to win material fractions that can be reused at the track construction site can be, so accordingly less new Material from the feed side (wagons 10a and 10b) are fed got to.

With the two excavation chains 82a arranged in the track treatment train and 82b according to FIG. 6, the entire track ballast and that cannot be sufficient stable substructure removed and in the working direction of the machine via a conveyor belt system on rail-transport vehicles, in 6 the two-story conveyor and silo wagons loaded and transported to an external processing plant or completely disposed of become. To save material, transport and disposal costs, it is advantageous if the excavated gravel is in a rail-accessible Ballast processing device of the track treatment train worked up so far for example by sieving and re-breaking depending on the degree of contamination for reinstallation in the Track is suitable and accordingly as an installation material on one corresponding section of the track treatment train is provided. In the case of heavily contaminated gravel, especially gravel with clayey ones Soiling, however, the problem arises that highly cohesive material remains on the gravel, with clay components both in the Funding as well as on sieve arrangements to loam bolls (gravel-like Balls) that cannot be screened off and thus the processing the gravel into question. Working up the ballast is furthermore characterized by clay-like and firmly adhering to the gravel grains other contaminations questioned. The solution is the Integration of a clay separation device and a ballast washing device in the track treatment train. The clay excretion device should serve, in particular, the clay bolls mentioned to remove the gravel. The washing facility is used on the gravel adhering dirt components, for example adhering clay or adhering fine components to detach from the ballast.

If the ballast is particularly contaminated by clay, it can however, be that one is due to a refurbishment of the ballast too much time and possibly insufficient quality results waived and the excavated ballast at the recycling plant including the clay separation device and the washing device past and an external processing or landfill supplies. External processing is advantageous in that it is reusable Substances can be separated from the dirty ballast and thus (by reducing the volume of the material to be deposited) landfill costs are reduced.

As explained with reference to FIGS. 4 and 5, one can ensure a materials supply corresponding to high work performance Transport in mixed condition. The material supply with For example, two different building materials (such as planum gravel [PSS] and gravel) can be simplified and there will be metabolic problems avoided. The separation of the substances takes place via a between the stock supply side and the material installation section of the Track treatment train interposed Neustoff separation module, for example the track separating screens 204 and 204 'according to FIGS. 4 and 5.

After separation in the Neustoff separation module, the ballast can still adhering to fine constituents, especially sandy fine constituents, that may be undesirable, for example because they are in their Total quantity of the technical delivery conditions of a customer for Gravel disagree. A solution here is the Neustoff separation module Downstream washing facility, preferably as a track Module is executed.

7a and 7b is an example of an inventive Track treatment train given on the new material feed side of a material installation section of a Neustoff separation arrangement has downstream ballast washing arrangement and on the Material removal and reprocessing side of a material excavation section of the track treatment train one of a ballast processing arrangement downstream clay separation device and one of these downstream ballast washer.

The track treatment train shown in Fig. 7 has the following wagons, Modules or units on: At least one of the removal of substructure materials or bedding residues for disposal or reprocessing serving silo and conveyor wagon A (for example, according to the known from the documents DE 32 19 025 C2 and EP 0 096 236 B2 Wagons); if necessary, at least one drive unit (at least a drive car) B with hydraulic supply for further modules or units of the track treatment train, in particular the screen wagon, the excavation chains and the transfer conveyor belts, in particular also the transfer conveyor belts for overburden to wagon A; a screen wagon C with a crusher system that has a pre-screen (e.g. double decker screen) with adjustment device for direct loading (bypass) in case of excess or Ballast contamination, a crusher for sharpening the ballast, and a secondary sieve (for example a monoplane sieve) for sieving undersize having; a track-running ballast washing system (ballast washing module or ballast washing machine) D with a system for removing Clay bulbs (can be switched on as required), a high-pressure intensive shower cleaner (here called cyclone cleaner), a high-pressure washing sieve, a water treatment plant to reuse the water in the washing system and / or for moistening certain intended for installation PSS materials or from old gravel; a track-going excavation and paving machine E with an excavation chain for the old ballast (the track bed of an existing track) and an excavation chain for the track substructure of the track and installation facilities for the reconstruction of the substructure or the ballast track bed made of new material or refurbished Old material; a material supply and stuffing module F with Transfer conveyor belts and material chutes and at least one Stuffer; a separating screen and ballast washing module G with at least a separating sieve for separating mixed gravel and PSS materials and a ballast washing system for washing off the Gravel after the separation of sandy impurities adhering to it; and at least one of the material feed of PSS material (flat gravel) and new ballast-serving conveyor and silo wagons H, for example corresponding to those from DE 32 19 025 C2 and EP 0 096 236 B2 known wagons, where due to the screening plant of the Module G per se does not matter whether the material is in separate fractions or as Gravel-gravel mixture is delivered. The separating sieve is present Washing module G, however, no conveyor and silo wagons accordingly downstream of the wagons 10a and 10b according to FIG. 4, so that the buffering capacity for materials that have already been separated is relatively small. For this reason, the material should be mixed are delivered, the mixing ratio of the demand ratio Corresponds to new materials when installing materials on module E.

It should be mentioned that the representation of FIG. 7 is largely is a schematic representation. For example the section of the module E comprising the old ballast excavation chain 82b in working direction A for problem-free gravel conveying in working direction to be extended. As explained in more detail below, the old ballast over conveyor belts running in an upper area of the train transported forward in the direction of work, for which the gravel accordingly is to be lifted vertically. For this purpose, it could be useful Conveyor belts of the main discharge belt in the joint part between D and E lower to lay. The transfer belts for the ballast run through the upper one Joint part between D and E.

The modules, units or wagons A, B, C and D are used to remove excavated material and for recycling gravel and can collectively as Excavation and recycling plant can be addressed. This In principle, the system can be used in conjunction with any formwork improvement and ballast cleaning machines can be used.

The old ballast and substructure excavating machine E can in principle of be of any design, especially with regard to the design of the excavation devices (Excavation chains) and the formation protection layer and ballast installation device. The foundation excavation chain 82a may preferably can also be used to excavate ballast so that the excavation chains 82b and 82b for a particularly large work output in parallel can be used if only the ballast to renew or to is clean, but the substructure of the track is not replaced.

The stuffing and new material transfer module F can be equipped with at least one Ballast silo and at least one PSS material silo, the silos, if necessary, by means of a correspondingly large ballast chute and a correspondingly large PSS material feed hopper can be formed (PSS = formation protection layer).

Below is the material flow for new material and old material explained, using a track treatment train as a subgrade improvement train (it becomes the ballast and the substructure of a track renewed) is assumed. From the old ballast excavation chain 82b (as well possibly from the excavation chain 82a by means of a connection to the transfer conveyor producing ballast conveyor belts 84b) Old ballast over ballast conveyor belts 84b-1, 84b-2, 84b-3 into a ballast screening plant 300 (for example for gravel 24/60) fed the for example a two-decker screen (preferably of the finger screen type) having. Sieve residues are conveyed via conveyor belts 302 and 304 at least one wagon A (corresponds to wagon 11 of FIG. 4), together with the removed overburden (especially substructure old material), as will be explained later. At the end of the conveyor belt is 84b-3 a bypass conveyor arrangement is provided which enables the old ballast not the screening plant 300, but the conveyor belts 304 Deliver overburden and thus to wagon A when reprocessing of the ballast due to excessive contamination or damage is not useful or not possible.

The excavated substructure material is removed from the excavation chain 82a Conveyor belts 84a-1, 84a-2, 84a-3, 84a-4 the one leading to wagon A. Overburden conveyor belts 304 fed.

A conveyor belt 306 leads from the screening plant 300 to a ballast crushing plant 308. The broken ballast is transported on a conveyor belt 310 fed to a post-screening plant 312 (for example for ballast 24/60), in the undersize, in particular by breaking up in the Crusher 308 undersize, to be screened. The sieve residues (Undersize or post-screening residues) are conveyed by conveyor belts 314, possibly including the conveyor belts 302, the overburden conveyor belts 304 and thus the overburden wagon A fed.

The one corresponding to a desired grain size, that is to say that of the screening plant 312 (for example, as a monoplane sieve) unscreened gravel is conveyed over conveyor belts 316 of a clay boll excretion device 320 supplied, which is also referred to as clay toner. The clay toner has at least one spiked roller with one or more (for example two) associated rubber rollers or foam rubber rollers interacts and excretes adobe from the gravel, and adobe bulbs that correspond to the nominal grain size of the ballast Have size and are therefore not eliminated by sieving can. The clay balls are speared by the spikes of the spiked roller, removed from the ballast and then stripped from the spiked roller. A bypass can be provided, which enables the ballast on Take the clay toner past, for example if the gravel is not or only slightly is infamous.

The ballast freed from the clay bulbs becomes a so-called cyclone washer 322 supplied in which the ballast in a fall from below is sprayed intensively with rotating high pressure water jets remove heavy dirt. Turbulence becomes coarse dirt effectively removed from the gravel. The gravel falls for example on a rotating disc with high-pressure nozzles, and is then thrown radially outwards due to centrifugal force. It can a bypass can be provided, which enables the ballast on the cyclone washer to pass if the ballast is less polluted. The arrangement may be such that the clay toner 320 and the Cyclone washer 322 shared bypass is provided.

The ballast, if necessary after passing through the clay toner 320 and / or the cyclone washer 322, is then placed on a high pressure washing screen 326, on which the ballast is shaken or vibrated by the washing sieve is promoted and brewed intensively with water from below and above.

In the area of the high-pressure washing screen 326 there are also a in module D. Wash water sedimentation basin with a drainage channel and (at 330) a water tank and a washing water treatment system are provided. The water treatment is preferably as follows: that of the cyclone washer 322 or waste water discharged from the high-pressure washing screen 326 placed in the wash water sedimentation basin so that solid components, especially sludge. In an upper level range water is removed from the washing water contained in the sedimentation tank and the water tank and / or the wash water treatment fed. Via a drainage channel integrated in the sedimentation basin sludge is fed to a sludge centrifuge 324 to remove the sludge to leave the water. The water freed from the mud becomes from the sludge centrifuge, the water tank and / or the wash water treatment fed. There is preferably a separate fresh water tank and a dedicated domestic water tank. From the process water tank or / and lines can be directly from the wash water treatment in the area of the ballast excavation chain 82b or the substructure excavation chain 82a in order to avoid dust formation To be able to irrigate old gravel before excavation. Furthermore, lines in the area of the formation protection layer installation part of module E be guided to moisten PSS material for installation.

The reprocessed and in module D at least one washing or Dishwashing treatment of old ballast, in the following also recycling ballast is called via conveyor belts 332-1, 332-2, 332-3, 332-4 and 332-5 fed a ballast chute 334, the same time serves as a ballast silo. The ballast installation device of the installation part of module E draws both recycling ballast from this hopper if necessary as well as new gravel.

The supply of new material takes place in the following way. The end the at least one wagon H (corresponds to wagon 11d of FIG. 4) pulled material, usually a mixture of new gravel and Planum gravel (PSS material) is transferred to a via a transfer conveyor 340 Screening system 204 "(for example for ballast 24/60) given, for example is carried out with at least one finger sieve. That through the Screening plant as screening residue PSS material is over Conveyor or transfer belts 342-1, 342-2 and 342-3 in a PSS material feed hopper 344 given, which also possibly fulfills a silo function. The The formation protection layer installation device of module E is moved as required PSS material from this chute.

The ballast screened off from the PSS material by the screening plant 204 "becomes via a conveyor belt 346 into a ballast washer 350 of module G supplied, for example, a high-pressure washing filter according to the Has washing strainer 326. The module G is also with at least one Water tank, a washing water settling tank, a drainage channel, a sludge centrifuge and wash water treatment. Intensive prewash using a cyclone washer or the like is usually not required for the new gravel material his. The module can with respect to the ballast washer and this assigned additional devices, however, be designed as module D.

The washed crushed stone is dem on conveyor belts 352-1 and 352-2 Ballast chute 334 fed.

You can also have your own ballast hopper for recycling ballast and provide a separate funnel for the new ballast, for example if you have recycled and new gravel in one want to incorporate a certain mixing ratio.

Would you like that through two ballast washing systems, namely a recycling ballast washing system and a new ballast washer Avoid investment and maintenance costs, so you can use the track treatment train even with a single ballast washer. This ballast washer is then transported by appropriate conveyor belts Both the refurbished old ballast, which may have been freed from clay bolls as well as the new ballast. It would be particularly useful for this the ballast washer in module E, preferably in the area of or the ballast chute. Would you like one conventional excavation and paving machine E could do so For example, think about an elevated conveyor arrangement the new ballast first in the working direction forward over the Feed module E to the washing device 322, 326 of module D, where it washed together with the reprocessed old ballast or is washed off. Appropriate silos can ensure that that the washing facility old and new ballast in a certain Mixing ratio is supplied.

Regarding the car wash 350 it should also be mentioned that one can also provide a bypass to bypass the car wash, so that in the case of delivery of single-variety, not with PSS material mixed gravel may not need a washing treatment can. Regarding those in the washing systems 350 and 322, 326 Sludge can be provided for this to be added to the new PSS material to be installed with this. The washing water treatment can be avoided or the effort for washing water treatment can at least be kept small if one is used Wash water for moistening the substructure material to be installed or used to moisten the gravel to be excavated or excavated. Fresh water carried in the track treatment train is then primarily for washing the ballast, but not for moistening it of the substructure material or the ballast.

Fig. 8 shows an embodiment variant of the track treatment train the gravel processing. The corresponding to the embodiment of Fig. 7 in the working direction, ie according to FIG. 8 from right to left, over the old gravel transported in aggregates shown in FIG. 8 becomes one first screening plant 400 fed, which in the present case as a double-decker screen is executed. In the screening plant, a larger grain size, such as the Grain size 35 to 60, and a smaller grain size, such as grain size 35 to 20, separated from each other. Of 100% gravel supplied, depending on the quality of the old ballast, for example 25 to 30% sieve residues (Overburden) via a conveyor belt 402 in working direction A for disposal removed. The larger grain size (e.g. 70% of the remaining gravel) a clay separation plant 420 (also called Clay toner identifiable) and fed from this to a crusher 408. The corresponding conveyor belts are labeled 404 and 406. For the case that the gravel is not or only slightly contaminated with clay is the gravel fraction with the larger grain size over a Conveyor belt 405 (bypass, shown in dashed lines in Fig. 8) on the clay toner 420 past the conveyor belt 406 and thus fed to the crushing plant 408 become.

The ballast fraction present after the screening plant 400 with the smaller one Grain is conveyed via a conveyor belt 410 on the clay toner 420 and on the Crusher 408 passed by. On this conveyor belt 410 is also the crushed stone treated in crusher 408, the two fractions (the broken gravel fraction with the larger grain size and the gravel fraction with the smaller grain) are merged again. Crusher 408 typically becomes a certain amount of Residues (overburden) removed (for example 5% of the supplied Amount of gravel), in this case on conveyor belt 402. Also from clay toner 420 excreted clay (especially clay bulbs) are in the present Embodiment given to the overburden conveyor belt 402.

The reunited fractions are then over a Conveyor belt 411 is fed to a post-screening system 412 for fine components sieve off. The fine constituents are, above all, also components resulting from the re-breaking, in particular chipping.

The post-screening unit 412 is preferably a two-deck screen with two different mesh sizes. The one on the seven remaining fractions will be reunited after screening, and then - as a rule - together via a conveyor 414 to be fed to a washing system 426. The use of two screen decks, possibly also more screen decks, in the post-screening unit 412 enables a larger processing capacity of the screening plant.

It comes for both the 412 screening plant and the 400 screening plant consider adding more screen decks depending on capacity requirements. For example, you could the upper screen deck of the screening plant 400, which in the For example, sieve the grain size 35 to 60, using two sieves for the Grains 60 to 55 and 55 to 35 replace their screened fractions but then again to the toner 420 and the crusher as a rule 408 gravel fraction to be fed are brought together. The same applies to the lower screen deck, which in the example is grain size 35 up to 20 sieves. One falls through an upper sieve Grain on a lower sieve, except for the lowest sieve, through which the overburden to be removed falls. In the case of the 412 screening plant, too the sieve residues (overburden) on the conveyor belt 402 in the working direction A transported away.

As already mentioned, the ballast fraction remaining after the screening plant 412 usually fed to the washer 426 to fine and Wash off fine components of the ballast and thus a ballast to provide with quasi gravel quality. To the car wash 426 additional washing units can be connected.

It can be provided that for good old ballast (especially clean Old gravel) by means of the corresponding gravel fraction Bypass conveyor belts (shown in broken lines in FIG. 8) on the clay toner 420 or / and on the crusher 408 or / and on the post-screening unit 412 or / and on the washer 426 is passed. The ballast processing arrangement shown in FIG. 8 can therefore optimally match the respective floor and Gravel ratios can be set and it is optimal Adaptation to different work situations possible, for example Formation improvement on the one hand and bedding renewal on the other.

The advantages of the arrangement shown in FIG. 8 are in particular a higher one Performance of the clay toner 420 and the crusher 408, since these only Gravel fraction with the larger grain size is fed. Only this gravel fraction normally needs to be broken up to the gravel stones to make it sharper. Since the clay in the screening plant 400 usually to loaves of clay about the size of the larger ones Rolls up gravel fraction, the clay is primarily in the Gravel fraction with the larger grain size should be included so that it is in the As a rule, only this gravel fraction of the clay excretion treatment is sufficient to undergo.

Since the crusher 408 and the clay toner 420 only the larger fraction get fed, these systems can be better in terms of set the optimal clay excretion or breaking result, and it there is less wear and thus a longer service life. In total, more crushed stone can be processed per unit of time. Also the Losses of ballast are reduced since the ballast fraction with the smaller one Grain is not broken, so no loss of this grain occur.

FIG. 9 schematically shows further exemplary embodiments in the partial figures 9a) and 9b) of the track treatment train. 440 denotes a fresh water car. 442 denotes a drive car. 444 denotes one Water purification car. 446 denotes a screening and washing car. 448 denotes a track-swirl breaker and 450 denotes a track-running pre-screen, each on its own or if necessary can be arranged in a common carriage. 452 denotes one Track-accessible excavation and PSS installation equipment. 454 denotes a Darning part, which may also be part of the device 452. 456 denotes a drive module. 458 denotes a transfer vehicle, the Receives new materials.

From the arrangement of the various components shown in the figure of the track treatment train relative to each other and in relation to the Working direction A results in the course of the different materials and conveyor belts transporting material fractions. So the excavated Old ballast in working direction A first of the screening plant 450 and then via the swirl breaker 448 of the sieving and washing device 446 fed. From this the processed ballast is then counter to the Working direction of the ballast installation site in the area of device 452 fed.

A difference between the two track treatment trains of Fig. 9a) and 9b) lies in the arrangement of the fresh water cart 440. According to FIG. 9a) the fresh water 440 is supplied to the fresh water line 460 Wash truck 446 fed, and that against the working direction A. Contaminated wash water is fed via a line 462 in the working direction A fed to the water treatment trolley 444. From the water treatment cart 444 is purified service water via a line 464 the PSS material installation point or PSS material installation device in the Area of module 452 fed to the PSS material as needed moisten. Furthermore, one can branch off from line 464 Line 465 of purified service water is fed to the washing module 446 to replace fresh water. For example, can be provided be that the ballast to be washed first consumes several process water Row of nozzles and then several fresh water consuming Row of nozzles happens, for example three rows of hot water and then three rows of fresh water nozzles. In a way, through the process water a "prewash" and the fresh water to a certain extent "Main wash" achieved.

From the water treatment module 444, domestic water can also be supplied via a line 466 can be fed to the module 452 in order to go there to the not to be excavated old gravel or the subgrade to be sprayed Avoid or reduce dust emissions when excavating.

Wet residues, especially sludge, are conveyed through conveyors, if necessary, lines 468, 469 and 470 from modules 444 and 446 in Working direction A transported away, in order, possibly together with other residues, to be disposed of.

According to FIG. 9a), the fresh water wagon 440 is in the working direction A. the drive car 442 arranged so that from the material discharge side (Disposal side) the fresh water supply can be replenished. According to 9b) is the fresh water wagon 440 on the new material supply side arranged so that fresh water can be replenished from this side Waggon can be fed. With this arrangement of the fresh water wagons is the fresh water via a line 460 'in the working direction A fed to the washing module 446, the possibility also being shown in FIG. 9b) it is shown that fresh water from line 460 'for moistening of the PSS material is fed to module 452.

Fig. 10 shows an example of two design options for the water treatment trolley 444 regarding the arrangement of two so-called Inclined clarifiers 500a and 500b. Corresponding to that shown in FIG. 9 Configuration of the track handling train becomes the inclined conveyors 500a and 500b are fed via lines 462 in working direction A to dirty water, which contains flocculants before entering the clarifier is, for example by means of a metering device 502, which in the line system 462 is included. That mixed with the flocculant Dirty water enters sloping pipes in a pool of water of the respective oblique clarifier. In the schematic in Fig. 10 indicated tubes lead to flocculation of the dirt components. The flocculated material sits on a floor or one there located conveyor 504a or 504b and is then off an outlet 506a or 506b, for example into an inlet funnel 508a or 508b or 508 one for pumping sludge and the same suitable pump, which is not shown in Fig. 10 itself. The flocculated material is then fed through a line 468 in the working direction A removed for disposal.

Clarified service water is produced from the inclined clarifiers in an upper area deducted from the water basin and against lines 464, 466 the working direction A fed for further use.

11 shows an alternative arrangement of components 400, 420, 408, 412 and 426 with respect to the working direction A, namely according to the Execution of the track treatment train according to Fig. 9. Otherwise corresponds 11 the embodiment of FIG. 8.

For example, one that has the water treatment wagon 444 Track treatment train will preferably continue continuously during track treatment move in working direction A. It can then go along of the track elevation changing to an excitation of the in the Water treatment units contain water for transverse sloshing movements that could interfere with water treatment. Also is a stimulation of longitudinal sloshing movements due to the water of changing incline or slope of the track not excluded, which could also be annoying. possibly water treatment units are also used, which are in a predetermined Position related to the horizontal plane need to work properly.

Fig. 12 shows schematically one possibility, like an automatic one Level compensation, for example in the transverse direction according to an occurring Track cant can be achieved. A wagon is shown 550 with a hydraulic actuator cylinder 552 and 554 in the transverse direction pivotable platform 556. A corresponding pivot bearing is shown symbolically at 558. The wagon has a sensor device on, the actual position of the platform 556 related to a target horizontal position detected. Based on the measurement result of the sensor device the hydraulic actuating cylinders 552 and 554 with hydraulic oil applies that the platform 556 in a horizontal (horizontal) Position is held so that on the platform Units, especially the water treatment units mentioned (such as inclined clarifiers) are kept in a horizontal position. In correspondingly, one could also compensate in the longitudinal direction of the rail provide.

If one starts from the conditions in the Federal Republic of Germany, so there is a maximum with a rail spacing of 1.435 meters Compensation requirement of about 200 mm corresponding to the maximum occurring Cant.

FIG. 13 shows a water treatment wagon designed according to the principle of FIG. 12 444 with at least one water treatment unit 500, mediating platform 556 in the transverse direction is pivotable. The dirty water supply and, where provided, the A flocculant is preferably added above the actual water treatment unit 500, for example in one Area 570. Fig. 13a shows a state without track elevation. The Platform 556 is in a horizontal position parallel to one Floor or frame 572 of the wagon. 13b shows a state with Cant. The floor or frame 572 of the wagon is accordingly inclined to a horizontal plane, but not the platform 556, which continues to assume its desired horizontal position.

According to one aspect of the invention, among other things, a track treatment machine or a track treatment train to renew the track substructure or / and proposed the bedding of a track. A reprocessing of the removed, preferably strong, is preferred dirty, track ballast of existing track systems provided. The Track treatment machine or the track treatment train is preferred executed in modular design and can advantageously a module "ballast washer" and a module "water treatment plant" or a module Have "gravel washing system with water treatment system". The Water treatment system enables water to be reused both within the washing cycle and in the area of responsibility the track treatment machine.

The track treatment train made up of individual modules is both for Improvement of the substructure as well as for cleaning the track bed in existing ones Track systems can be used. Substructure material and / or track ballast is made the track, preferably under a rolling wheel, with standard if necessary Excavation chains added and on conveyor belts for loading or to the individual reprocessing modules are promoted for reprocessing, preferably in the working direction.

The excavation module preferably leaves a separate loading of substructure material and old gravel too. Both fractions can be in suitable funding Silo wagons are loaded and unloaded separately.

Another work module consists, for example, of a two-deck screening machine (Finger sieve / mesh sieve) with which the dismantled and used Reuse suitable crushed stone in both the first and in the second stage separated from loose impurities and simultaneously in two Grit is classified. The sieve residues become the overburden fed and loaded. The work module also has a crusher, who has the task of at least a predetermined gravel stones Grain to undergo a regular treatment to produce the required sharp-edged condition (like new ballast). Preferably becomes only a fraction of larger grain size, but not a fraction smaller grit fed to the crusher, making the fraction smaller Grain in the crusher is not destroyed. The smaller fraction can preferably by bypassing the fraction again be fed.

In a further work module, the resulting crushed stone fraction is over treated another screening plant again, especially in the case of Screening broken or loosened parts and thus the To further improve the quality of the recycled ballast. The screenings can be added to the other residues. The resulting crushed stone is usually another, having a ballast washer Work module fed. However, it is preferably provided that the Ballast with less pollution or / and with minor Track systems bypassed the ballast washing system and immediately for reuse of the built-in part of the track treatment machine can be supplied.

The ballast washer enables that for the remanufactured Track ballast achieved a very high quality, up to new ballast quality and accordingly the highest technical delivery conditions enough. The ballast washer can be one or more Have washing screens on which the ballast is created using high-pressure nozzles adhering dirt, which cannot be removed by sieving, is removed from it can be. The at least one washing filter can advantageously at least a washing centrifuge upstream. An if necessary is preferred switchable clay toner provided to be strong even by clay to be able to work up dirty gravel.

A further work module is preferably provided, which is a reprocessing of water contaminated during the washing process, so that the Reduce fresh water supply. The polluted water will for example in a so-called clarifier with the addition of vog Flocculant cleaned at least to the extent that it is mixed with fresh water can be used in the car wash. The processed Process water can also be used to moisten subgrade sand or used for the dust-free removal of old ballast. The Fresh water consumption can be reduced by this type of water reuse be greatly reduced, for example by 80 to 90%. Since that If water remains in the working cycle, there is no pollution. The discharge (sludge) can be pumped to the rest of the excavation (overburden) and sieve residues for normal removal.

The water treatment module can advantageously be equipped with two inclined clarifiers be executed. Compared to only a longer length oblique clarifier it is advantageous to use two shorter inclined clarifiers, as the Length of the inclined clarifier the cleaning effect becomes less. Further The advantage is that in the event of a malfunction one of the clarifiers, for example, if a sludge discharge belt fails, with accordingly lower performance with the other inclined clarifier can. The installation of two shorter clarifiers is also an example a standard rail car is structurally simpler than installing just one longer clarifier.

The work modules mentioned above can also be used as road vehicles Modules for recycling demolition materials.
