Description

 Bedding method and apparatus with drainage mat incorporation

The invention relates to a cleaning method and a cleaning device for track bodies (ballast bed including embedded sleepers and routed rails, also in points and crossings areas), in which a drainage mat is aufgeiegt on the renewal of the ballast bed on the flat bottom.

Bedding cleaning methods and devices are basically known. In these methods and equipment, the ballast is first removed from the track or track next to the track below the concrete sleepers and tracks, and the tracks are kept at a distance from the floor siding. After removing the ballast bed or gravel body, the flat bottom sole is leveled and compacted with the aid of a vibrator, so that prepared or new ballast can be brought to the pianole sole. This constructed ballast bed is then compacted in a known manner. The raised tracks including sleepers are embedded in the ballast bed in a manner also known per se. Such systems and devices are described for example in DE-U-201 14 163, DE-U-2Q1 07 518 and EP-A-I 253 246.

From EP-A-1 619 304 a track superstructure is known whose ballast body is foamed in its load transfer areas. In addition, there is a drainage mat below the ballast body on the pianole sole.

The object of the invention is to enable the introduction of a drainage mat in the cleaning / renewal of a ballast bed. To solve this problem is proposed with the invention, a method for cleaning or renewal of the ballast of a ballast body located on a flat sill track railway without removal of rails and sleepers (rails), wherein in the process - the gravel removed until the free allocation of the planing sole is, the rails and sleepers in a spaced from the flat sole

Positioning are held, between the rails and sleepers on the one hand and the planum sole on the other hand drainage mats are spent on the flatbed sole and - below the rails and sleepers and on the drainage mats

Ballast body is produced in which the sleepers are embedded.

According to the invention, therefore, individual drainage paths or individual drainage mats are brought from the side of the track superstructure under the raised tracks including sleepers on the flatbed sole, whereupon subsequently the introduction of the new or purified gravel occurs. After the prescribed production of the ballast body or the track superstructure can then, if desired, carried out the partial expansion, as described in EP-A-I 619 305. A variant of the incorporation of a pourable, foamable reaction mixture is described in the application filed at the same time as the Applicant's present application entitled "Process for producing a partially expanded track superstructure". The content of this second application is hereby incorporated by reference into the subject of the present application,

The drainage mat can be pulled laterally and transversely to the longitudinal extent of the ballast body over the flat sole or pushed until it has reached its prescribed position. This has the advantage that it will again level the piano number. Alternatively, it is possible to spend the drainage mats in the raised state under the tracks or thresholds, in order to then settle them on the flat bottom sole. The drainage mat supply and installation system is expediently designed to be movable on the system unit intended for ballast cleaning. conventional Unfortunately, ballast cleaning is a continuous process in which a system is moved over the track. During the introduction of the drainage mat, it may be expedient if there is no relative movement between drainage mat and planum in the longitudinal extent of the ballast body. In that regard, therefore, the drainage mat feeding and above the flat sole or on this positioning should be movable relative to moving on the track machine frame unit.

The drainage mats are stacked, for example, in a magazine or similar device. They are taken individually and spent on guides or the like side of the tracks under them. Alternatively, it is possible to deliver the drainage mats from a roll (and, if appropriate, to cut them accordingly if the corresponding part of the drainage sheet material is on the planum roll).

The drainage mats, which are likewise described in the aforementioned EP-A-1 619 305, have on the top and bottom side a fleece, in particular a geo-textile, which protrudes on respective opposite edges of the mat above or below. By way of example, the nonwoven on the upper side protrudes beyond a longitudinal edge of the drainage mat running transversely to the track extension, the fleece protruding on the underside against the opposite longitudinal edge of the drainage mat. The fleece can also be laid on the planum sole or drainage mats before and after the drainage mat installation. In this case, the nonwoven layer can be glued by applying an adhesive with the drainage mats, wherein the adhesive can be sprayed on.

Finally, it is possible that the planum sole is compacted and / or leveled after removal of the ballast and before placing the drainage mats.

The above object is also according to the invention by means of a device for introducing drainage mats in the space between the sill of a track superstructure and its rails and Sleeper (track) solved with the ballast body removed, wherein the device is provided with an out-of-space bearing surface on which a plurality of Drainagematten be positioned, and - a Uberfuhrungseinheit for transferring the drainage mats in the

Space between them and to lay down the drainage mats on the platform floor.

As already mentioned above, in the device according to the invention, the drainage mats are inside a magazine or the like. on a bearing surface of a movable on or above the track chassis, which further comprises a Uberfuhrungseinheit for Überfuhren the drainage mats from the magazine into the space and to deposit the drainage mats on the Planums- sohSe. The drainage mats in the magazine may be positioned next to one another in a stack or upright. The transfer unit is expediently provided with two bearing surfaces which serve to support and retain the drainage mats at their longitudinal edges parallel to the transfer unit when the drainage mats are located in the intermediate space. To deposit a drainage mat held in this way, the support surfaces are moved away below the drainage mat so that it falls (from a low height) onto the planar sole. Alternatively, it is possible to initially place the (next) drainage mat overlapping on the already deposited adjacent drainage mat, in order then to pull or move it as far as the already deposited drainage mat during movement of the frame until both drainage mats are "edge-to-edge". lie on the Planumssohie.

It is expedient if the support surfaces are the lower legs of L-shaped or U-shaped guide rails which project into the intermediate space between the track and the flat sole. The support surfaces are advantageously moved away under the drainage mat in such a way that they are pivotable about swivel axes parallel to the longitudinal edges of the drainage mat and thus can be folded downwards. The transport of the Draina From the magazine to the area below the track and above the flat bottom sole is preferably carried out with the aid of a sliding or transport unit through which a drainage mat is driven either by gravity or by drive rollers (for example friction or spiked rollers) ,

One of the essential features of the device according to the invention is the introduction of the drainage mats from one of the longitudinal sides of the track superstructure, ie from one of the two sides into the space between the sill and the raised track (rails including sleepers), this movement of the material of the drainage mats in the form of individual cut mats or quasi as continuous material or web material, wherein in the latter case, a cutting device is provided which, after the BahnmateriaS has been advanced by the length of the next drainage mat to be deposited in the space between the tracks and the flat sole, is cut off.

The invention will be explained in more detail with reference to an embodiment and the drawing. In detail, they show:

1 in side view and divided into two parts a machine for cleaning and / or renewal of the ballast bed of a track,

2 shows a section along the line II-II of Fig. 1,

3 shows a section corresponding to the plane II-II of FIG. 1 when using an alternative plant component for depositing the drainage mats,

4 shows a section along the line II-II of FIG. 1 in a further alternative embodiment of a plant component for the announcement of web-shaped drainage mat material and Fig. 5 is a view along the arrows VV from the side into the space between the tracks and the flat sole to illustrate the Vorpositionierung and storage of Drainagemattenmaterials.

1 shows a machine 10 with which the ballast body 12 of a track superstructure 16 located on a surface 14 can be replaced in a through-opening operation without the track 18 _f, ie the rails 20 and sleepers 22, having to be removed. The track 18 remains rather with removed gravel body 12 in the raised state above the subgrade 14, so that there is a gap 24. The structure of the system 10 is essentially the removal of the old ballast, the removal of the ballast of the old ballast, its cleaning and / or renewal and the supply of the renewed or cleaned ballast and its introduction into the space 24 and its compression identical with known systems of this kind, as described for example in DE-U-201 07 518. Therefore, at this point on the aforementioned plant components will not be discussed. Rather, reference is made in this context to the aforementioned document.

The difference of the system 10 of FIG. 1 to the known systems of this type is that (in the direction of travel) in front of the system component 26, with the new or cleaned ballast is applied, and before the system component 28, compacted with the ballast a device 30 is arranged, which serves the introduction and storage of Drainagematteπmaterial in the gap 24 between the track 18 and the flat sole 14. Several variants of this device 30 are now shown in FIGS. 2 to 4 shown. In these variants, it is assumed in each case that the device 30 is supported on the flat sole 14, for example by means of tracks. It is also possible that the device is attached to the portal-like frame of the machine 10 and hangs down.

2, the device has a frame 32 that is supported on both sides of the track 18 via tracks 33 on the flat sole 14. The frame 32 carries a stack 34 of superimposed drainage mats 36. These drainage mats 36 are, for example, compressed elastomeric plastic recl late, as is known per se and also described in EP-AI 619 305. The uppermost drainage mat 36 of the stack 34 is or the like using a Transportroüe. Drive element 38 (separating device) laterally moved from the stack and enters a transfer unit 40, which has a sliding or transporting device 42. After removal of the uppermost drainage mat 36, the stack 34 is lifted by means of a drive (not shown) in the direction of the arrow 35. The transfer unit 40 ER- extends laterally and above the Gieisoberbaus and or its bearing surface 46 leads from the Maga ^¬ zin 44 laterally outside of the device 30 ent ^¬ long and downward. With the aid of this sliding or transporting device 42, the supplied drainage mat 36 is transported to a positioning and depositing unit 48, which projects into the intermediate space 24 between the track 18 and the sole plate 14.

In the positioning and depositing unit 48, the drainage mat 36 is located between two opposite guide and support rails 50, which in this exemplary embodiment are U-shaped and opposite each other. The lower legs 52 of these guide and Haiteschienen 50 form Auflagefiächen 54, on which the drainage mat 36 rests and by which it is held. By folding down the legs 52 about the pivot axes 56, the held drainage mat 36 is released to be placed on the flat sole 14. Such effected the deposition of a drainage mat 36, that it rests tightly against the previously stored adjacent drainage mat 36 and in particular the edge and the edge is arranged with this drainage mat 36 are ^¬.

The variants of the device 30, as shown in FIGS. 3 and 4 differ from the device 30 according to FIG. 2 by the type of storage of the drainage mats 36 and / or the drainage mat material. According to FIG. 3, the drainage mats 36 are standing upright next to one another on the bearing surface 46 and are moved in the direction of the arrow 58 to the side until the foremost drainage mat 36 enters the transfer unit 40. From this point on, the process of transferring the drainage mat 36 as described with reference to the device 30 according to FIG. 2 repeats into the area between the track 18 and the planing sole 14.

In the exemplary embodiment of the device 30 according to FIG. 4, the drainage mat is present as web material 59 and rolled up. The storage area is thus formed here by a roller or roller 60. The web-shaped drainage mat material 62 reaches the transfer unit 40 and via to the positioning and depositing unit 48, where it comes to rest on contact with a stop 64. With the aid of a deflecting device 66, the web-shaped material is cut to the required length to than then, as described above, to be placed on the flat sole 14. Also in the directions before ^¬ 30 as shown in FIGS, 2 and 3, a stopper 64 can be provided (in FIG. 5, not shown).

The roller 60 carrying the rolled-up drainage sheet material 62 may be driven. Alternatively or additionally, the transfer unit 40 may have transport rollers or similar transport elements for advancing the drainage web material 62.
