Abstract

The invention relates to a method for replacing a rail for track vehicles, which is laid in a fixed running track by means of ties. According to said method, at least the old ties (11a) of the old rail (10a), which is substantially composed of running rails (14) and the old ties, are replaced with new ties (11b). Some of the old ties (11a') are first removed from the recesses thereof in the fixed substructure (13) of the running track and are replaced by lifting/directing ties (15) which are inserted into the recesses while the other old ties (11a'') initially remain in the recesses (12'') thereof and support the running rails. The remaining old ties (11a'') are replaced with new ties (11b'') once the rail has been placed in the desired vertical and lateral position with the aid of the lifting/directing ties. The lifting/directing ties are then replaced with new ties (11b') once the previously installed new ties (11b'') have been blocked in the recesses (12'') thereof in the position obtained following the vertical and lateral adjustment.

Description

Applicant: RTE Technologie GmbH, MariahilfStraße 29, A-6900 Bregenz Title: Procedure for the renewal of a track laid by means of sleepers in a fixed carriageway as well as a threshold for use in the procedure

The invention relates to a method for the renewal of laid by means of sleepers in a fixed carriageway track for rail vehicles, wherein at least the old sleepers of a substantially consisting of rails and the old sleepers old track are replaced with new sleepers, the sleepers are arranged in recesses of a fixed roadbed. The invention is further directed to a Heberichtschwelle for the renewal of a laid by sleepers in a fixed track track for rail vehicles, which can be used advantageously in carrying out the method according to the invention.

Not only tracks laid in ballast for rail vehicles require renewal after a few years of operation, but also tracks that are laid on a fixed track have only a limited service life and must be renewed after their expiry. The renewal of such a track is particularly problematic when it comes to at least partially maintain rail traffic, because in such cases can usually be worked on the track only during a few hours at night and / or weekend, if no trains roll over the track or at least be temporarily diverted. Such conditions occur, for example, in the rehabilitation of subway tracks, which are difficult to master due to the limited space here. The previously used in the rehabilitation of laid in a solid road subway tracks for use methods are very complicated, expensive and tedious, since in the short breaks, where there is no rail traffic, only a short track piece can be renewed and this one Variety of steps is required, which make the known methods so expensive. The object of the invention is to provide a considerably simpler, faster and cheaper way to renew a laid in a fixed track track compared to the known method, which makes it possible to use the track during construction breaks anyway makeshift, so that entire routes not permanent must be shut down.

This object is achieved with the method according to the invention in that a part of the old sleepers is removed from their recesses and replaced by inserted into the recesses Heberichtschwellen, while the other part of the old sleepers initially still remains in their recesses and supports the rails, and that the first Remaining part of the old sleepers is replaced by new sleepers after the track has been set up by the Heberichtschwellen in the desired height and lateral position, and that the Heberichtschwellen be replaced by Neuschwellen after the previously installed Neuschwellen in their received after the height and side device location in their recesses were arrested.

Basic feature of the method according to the invention is therefore not to replace all the thresholds of a track or track sections at once, but initially replace only a certain part of old sleepers by temporary Heberichtschwellen, while the remaining part of the old sleepers initially maintains its function as a supporting body for the rails. Advantageously, it is possible to work here so that first every second (or third, fourth) old threshold is replaced by a temporary threshold value. The remaining (secondary) old sleepers remain in their recesses and support the rails safely enough that a rail vehicle can certainly drive at a reduced speed over the track safely. With the help of the Heberichtschwellen can then be aligned in the new desired height and lateral position in a further downtime, in which can be worked on the track, the Heberichtschwellen not only allow the exact alignment of the track, but also resulting from the driving Forces can be safely removed into the roadway substructure. The remaining (secondary) thresholds can then against new thresholds are exchanged, which are after their installation on the rails initially with some play in their respective recesses and also as a result of the defined by the Heberichtschwellen, correct height and lateral position of the rails to which they are attached, then already in their correct Orientation. In this they can be locked in the recesses and as soon as this locking is done permanently, the Heberichtschwellen can be removed and replaced with new thresholds.

Advantageously, the method according to the invention is characterized by the following method steps:

Removing individual Alt-primary sleepers from their respective recesses, wherein between two successive in the track direction primary sleepers at least one Alt-secondary threshold to support the rails remains in their respective recess;

Installation of the temporary lifting thresholds in the vacant recesses of the primary sleepers and connection of the lifting thresholds with the rails;

Removing the old secondary sleepers from their respective recesses;

- Aligning the rails in their desired height and lateral position relative to the fixed roadway substructure by means of Hereizschwellen;

Arranging new secondary sleepers in the secondary recesses released by the removal of the old secondary sleepers, connecting the new secondary sleepers with the rails and permanently locking the new secondary sleepers in the secondary recesses,

Expansion of the residential thresholds; Placing new primary sleepers in the primary recesses released by the expansion of the lift thresholds, connecting the new primary sleepers to the rails, and permanently locking the new primary sleepers in the primary recesses.

In this method, the new waves in the recesses are preferably locked by means of a potting compound such as Vergußbe- tone. The Heberichtschwellen be appropriately temporarily fixed in the primary recesses and can then easily disassemble after locking the Neuschwellen in the adjacent secondary recesses. In order to ensure the required rigidity of the track alone with the Heberichtschwellen, it is advantageous if the Heberichtschwellen be fitted positively in the primary recesses. To be particularly advantageous, it has been proven to set the Heberichtschwellen in the recesses initially in their desired altitude and then to lock in the directions parallel and transverse to the rails in the recesses. The Heberichtschwellen can be adjusted and / or locked in the recesses by means of clamping elements, in particular wedge elements, eccentric elements and / or screws.

In a particularly advantageous embodiment of the method according to the invention, the Heberichtschwellen be arranged limited height adjustable in the recesses, so that when driving the track with a rail vehicle, the track can give something and thus height compensation is achieved, even if the track is not yet set up exactly in its desired altitude has been. In this context, it has proved to be expedient if the clamping elements are elastic, deformable clamping parts, which rest firmly in the clamped between the recess and Heberichtschwelle state on the side walls and allow the height mobility of the Heberichtschwelle in the recess due to their elasticity. In the method according to the invention, the track can be exchanged in track sections whose length is a multiple of the distance of the sleepers from each other. As already indicated, preferably every second, third or fourth old threshold is removed in the old track as Alt-primary threshold and replaced by a Heberichtschwelle. A particularly effective method of operation, in which a comparatively long track section can be renewed within a short time, results when, for the expansion of the old primary sleepers, the rails of the track or of the track section, together with the old secondary sleepers attached thereto, extend a little way out of the Recesses is raised and the old primary sleepers are then removed from their primary recesses. It is also possible for the expansion of the old primary sleepers, the rails of the track or the track section together with the attached old primary sleepers a bit far from the recesses and then remove the old primary sleepers from the rails. The Heberichtschwellen can be arranged in the then released primary recesses and connected after lowering the rails with these, during this work, the old-secondary sleepers are still mounted and provide a sufficiently secure support of the rails of the track. After aligning the Hebericht- swell in the correct height and lateral position, these assume the supporting function of the track, ie the remaining Altsekundäschwellen then provide only for a lateral or rail parallel guidance, while acting due to the weight of the rails and rail vehicles weight forces be removed via the Heberichtschwellen in the roadway substructure.

It is advantageous if the new secondary sleepers are released from the rails for curing the potting compound locking them. The new secondary sleepers are thus initially held only as long as the rails in their position until the locking potting compound has set so far that the thresholds can not sink further alone in the potting compound due to their own weight, but retain their once set position. They are then released from the rails and preferably, after releasing the new secondary sleepers from the rails, they are lifted by means of the lifting rails. Richtschwellen raised by a certain amount, which ensures that when crossing the track with a rail vehicle, the new secondary sleepers are then not burdened and thereby can change their position again. Similarly, the new primary sleepers for curing the locking compound locking them are preferably also released from the rails, which are expedient to be raised by relieving the Neu-Primärschwellen of the rails by relining to the new secondary sleepers by a certain amount. A comparable effect is also achieved when the primary sills and / or the secondary sills are secured to the rails during alignment and locking using relining pieces, with the sealing compound locking the respective sills temporarily removing the relining pieces and the sills be temporarily detached from the rails. Also in this embodiment of the method according to the invention it is ensured that the thresholds, which were recently installed and encapsulated and in which the potting compound is not fully cured, located at a sufficiently large distance from the rails, so that the support forces of the above Rail moving vehicle not be worn over the thresholds, the potting compound is not cured.

The Heberichtschwelle created with the invention, which can be used in a particularly advantageous manner in the method according to the invention, has at least one insertable into a recess in the fixed carriageway base threshold block and a lockable on the rails adjustment plate, which is adjustable at least in its height relative to the threshold block , For this purpose, the Heberichtschwelle be provided with at least one adjusting spindle having height adjustment.

In particular, for weight reasons, it has proven to be advantageous if the Heberichtschwelle has two threshold blocks with associated adjusting plates, wherein the threshold blocks are connected to each other by means of preferably removable tie rods or connectable. The Heberichtschwelle invention is then so after Type of a two-block threshold configured, wherein the two threshold blocks are located substantially only below the two rails and the required track spacing between the rails is determined by the tie rods.

It is useful if an elastic support sole is arranged on the underside of the sleeper block, which allows a sinking of the Heberichtschwelle in this receiving recess within limits when a rail vehicle travels over the track. The support sole may preferably be made of polyurethane or the like. consist. To lock the Heberichtschwelle in the receiving recess in the directions that lie in the plane that is spanned by the two rails, preferably between the threshold block and the recess on the outer face and on the front and rear of the threshold block effective clamping elements provided, which may consist in particular of wedge elements, eccentric elements and / or screws.

Further features and advantages of the invention will become apparent from the following description and the drawing, wherein a preferred embodiment of the invention is explained in more detail by way of example. It shows:

10 shows a detail X of the Heberichtschwelle of Figure 9 in a view and partly in section. and

Fig. 11 shows the subject of FIG. 10 in a plan view. In Figs. 1 to 8, the essential steps of the inventive method for the renewal of a track 10 are shown, which is laid by sleepers 11 in a fixed lane. 1 shows the old track 10a to be renewed, in which the old sleepers IIa, for example old wooden sleepers, are arranged in recesses 12 of a fixed carriageway substructure 13 and support the rails 14. In particular, the track may be the subway or other suburban railway track, and the work required for the interchange may take place only during the comparatively short shutdowns during the night when the track is not being used. Under these conditions, after a few hours, during which it is possible to work on the track, at least its provisional trafficability must be ensured for the next day.

In carrying out the method according to the invention, a part IIa ^{1 of} the old sleepers IIa is first removed from their respective recesses 12 '. For the removal of these old primary sleepers IIa ¹ , the rails 14 of each second old sleepers IIa are loosened in a track section to be renewed, which may have a length of, for example, 25-10Om, and the rails are then connected to the old primary sleepers IIa which they do not release 2), whereby the old primary sleepers IIa ¹ are lifted out of their respective primary recesses 12 'while the old secondary sleepers IIa''previously released from the rails are in their original position in the secondary recesses 12 '' remain.

The Alt primary sleepers IIa 'can be dismantled from the rails 14 in the raised state of the track section. The vacated primary recesses are cleaned, freed from any existing loose concrete parts and roughened if necessary on their side surfaces and their bottom. Subsequently, in the primary recesses 12 'Heberichtschwellen 15 are used, the structure of which is shown in more detail in Figs. 9-11 and serve to reorient the track and to a temporary support of the rails, the sufficient is to allow a drive over the track even without the support of other (secondary) thresholds.

After inserting the lifting thresholds 15 into the primary openings 12 '(FIG. 3), the rails are lowered and firstly fastened again to the old secondary sleepers IIa ¹ ' remaining in the secondary openings 12 "(FIG. 4). The rails are thus restored to their original orientation and the track can be re-used after re-attachment of the rails to the old secondary sleepers IIa ¹ '- possibly with reduced travel speed.

In the next step, the Heberichtschwellen 15 are screwed with suitable adapter plates 16 at the bottom of the rails 14. They can then be set up in the desired height and lateral position in the primary recesses 12 '. The Heberichtschwellen consist for this purpose essentially of two separate threshold blocks 17a, b, which are connected to each other by means of demountable tie rods 18 and at their top an adjustment plate

19, which carries the adapter plate 16 for connection to the respective rail 14 and which can be adjusted by means of adjusting spindles in their altitude above the threshold block 17. At the front

20 each threshold block 17 and at its front and rear sides

21 and 22, the Heberichtschwelle can be adjusted and locked with clamping elements 23 in the receiving recess 12 'transversely to the rails and in the longitudinal direction. In this case, a locking is sought with a defined force, which can be done for example by wedge elements, eccentric and / or screws, which are not shown in detail in the drawings.

When setting the Heberichtschwellen is working so that first the adjustment plate and the overlying rail are connected by means of the adapter plate 16 and then lowered by means of adjusting spindles 24 for height adjustment of the underneath threshold block 17 so far that he firmly on the floor 25 of Recess 12 'rests. The threshold block is provided on its underside with an elastic support sole 26 made of polyurethane, the unevenness in the bottom surface 25 of the recess 12 ' compensate and ensure the passage of the temporarily supported by the Heberichtschwellen track a certain flexibility of the same.

After the Heberichtschwellen were thus brought into their correct altitude, they are braced laterally and in the rail longitudinal direction in their recesses with the help of the clamping elements 23, so that the Heberichtschwellen can take over the supporting function for the track. It is now possible to replace the old secondary sleepers IIa ¹ ', which still remain in the secondary recesses 12 ", with new secondary sleepers.

The expansion of the old secondary sleepers can take place in the position of the track, in which it is supported and aligned as described by the sleep thresholds. In this position, therefore, the rails 14 are in the lowered state and it is necessary to pull the Alt-secondary sleepers laterally under the rails, to which initially their connected to the rails adapter plates are completely dissolved and dismantled. Alternatively, it is also possible to disassemble the rails after setting up the Heberichtschwellen of these again and then raise them together with the still connected Alt-Sekundärschwellen IIa '' and then dismantle the Alt -Secundärschwellen of the rails. The then released secondary recesses 12 '' are then cleaned in a similar manner as before the primary recesses 12 'and optionally roughened or milled at the bottom and side surfaces and thereby prepared for the reception of new thresholds.

The new secondary sleepers IIb ^{1 1} are inserted into the vacant secondary recesses 12 "(FIG. 6) and connected to the rails of the lowered track. In this case, the new secondary sleepers IIb ¹ 'are aligned in the secondary recesses 12''in such a way that they maintain an approximately equal distance from the side surfaces 27 of the recesses both in the front and in the rear. The new secondary sleepers are attached to the rails with the interposition of a relining, which in the simplest case of a Adapter plate can be formed, as it comes with the Hebericht- thresholds used.

After ensuring that the track is correctly aligned after placing the new secondary sleepers in the secondary recesses and attaching them to the rails, the new secondary sleepers IIb ^{1 1} may be potted in the secondary recesses 12 "receiving them low-shrinkage poured concrete, as is standard in the production of tracks in a fixed track used. The grout 28 encloses the Neu-secondary sleepers at their ends and their side surfaces and possibly flows into the space between the bottom of the recesses and the underside of the thresholds, so that the previously existing space between the new secondary sleepers and the secondary recesses is completely filled ,

Once the grout has set and the threshold can no longer sit or move due to its own weight in the potting compound, the attachment of the new secondary sleepers to the rails is released again and the underfill or adapter plate between the rail and new secondary sleepers is removed. so that the newly installed sleepers maintain a sufficiently large distance from the rails during the curing process of the Vergußbeton, so that a rail vehicle or train safely go over the track, without in this case the new secondary sleepers are already burdened by the rail vehicle.

After the potting compound, with the Neu-secondary sleepers IIb '' were locked in their Sekundärausnehmungen 12 '' is completely cured and can be loaded by the forces acting on the track forces, the Heberichtschwellen can be removed and replaced with new primary sleepers IIb ' become. This removal and replacement is analogous to the processes described above in connection with the secondary sleepers. The rails are thus raised after releasing the Hereizschwellen arretierenden clamping elements together with the Heberichtschwellen, the Heberichtschwellen dismantled from the rails and Neu-primary sleepers IIb 'are inserted into the primary recesses 12' and then the rails are lowered again and then attached to the already installed and fixed with the cured potting New secondary sleepers IIb ' ¹ , the attachment in turn with the interposition of Unterfütterungsstϋcken or use of Adapter plates takes place, so the rails do not rest directly on the actual thresholds. The new primary sleepers IIb ¹ are also secured to the rails using shims and placed in their desired position and are then cast in the primary recesses with grout 28. Again, after the setting of the concrete, the relining piece between each new primary sleeper and the rail is removed, thereby providing a sufficiently large distance between rail and sleeper so that the deflections of the rails occurring during the crossing of a rail vehicle do not affect the newly installed primary sleepers can break through and hinder the bonding process.

It can be seen that the thresholds of long track sections can be replaced simultaneously with the method according to the invention, wherein the individual process steps can be carried out substantially detached from each other, ie there can be interruptions in the individual operations, while still ensuring the passability of the track during these interruptions is. The method is thus particularly well suited to the replacement of a track, which must remain open for traffic during most of the day and which can only be worked for a few hours during the day or at night. In carrying out the method according to the invention, the track is only ever passable for relatively short periods of time; the much time consuming hardening process of Vergußbetons requires in a particularly advantageous manner, no interruption of driving, since the newly installed sleepers are located at a sufficiently large distance below the rails so that it does not burden during curing of the Vergußbetons by moving over the track rail vehicles become. The invention is not limited to the illustrated and described embodiment, but various changes and additions are conceivable without departing from the scope of the invention. For example, it is not absolutely necessary to divide the ratio of primary and secondary thresholds as 1: 1, that is to say to make the described arrangement in which each primary threshold lies between two secondary thresholds and each secondary threshold lies between two primary thresholds. It would also be quite possible to work with fewer thresholds and, for example, to expand only every third or fourth threshold in the track as a primary threshold and replace it against Heberichtschwellen before then the remaining (secondary) thresholds are exchanged in the manner described. It is also understood that in the exact device of the track this is adapted not only to the course of the rails in the old track, but that in the alignment and special track alignment are used, as in the manufacture of track tracks, especially those in solid pavement in general are known and can be adjusted with their help track, elevation, inclination angle, etc. Such methods and devices for setting up tracks are known and will not be explained in detail here.

When casting the sleepers in their recesses with Vergußbeton it may be necessary or appropriate, depending on the local conditions, to attach a formwork to effectively prevent accidental leakage of the potting compound from the gap to be filled. In order to prevent damage to the newly installed thresholds or premature loading of the new sleepers, it is also possible, instead of the relining pieces to be removed during the setting operation, to raise the track by a certain predetermined amount with the aid of the lifting thresholds, for example by means of the adjusting spindles 24 can be made, which are then rotated by a predetermined amount and so raise the adjusting plates 19 relative to the threshold blocks 17 by the desired amount, for example, about 2mm. The newly installed sleepers are preferably concrete sleepers, in particular bi-block sleepers, whose two sleepers are interconnected with tie rods.
