Definitions
- the invention relates to a method for cleaning a ballast bed of a track by means of track-bound machines, with a cleaning machine being used to remove ballast located under a track grid with a ballast removal device, with cleaned and/or new ballast being removed in several layers in relation to a working direction behind it a ballast installation device and a ballast train is introduced into the track and the introduced ballast is compacted by means of a tamping machine and a stabilization machine.
- Ballast tracks have properties that ensure a safe and efficient
- ballast must have sufficient stability and elasticity through a suitable grain distribution and good interlocking of the individual ballast grains. A low proportion of fine grain and high sharpness are decisive for this requirement.
- ballast Over longer periods of time, dynamic operating loads and weather influences mean that the ballast increasingly loses its positive properties.
- the ballast In order to restore an intact ballast bed, the ballast must be cleaned, supplemented or completely replaced.
- a machine for cleaning ballast is known, for example, from AT 520989 A1.
- a ballast removal device designed as an endless clearing chain, the ballast located below the raised track panel is continuously removed and fed to a cleaning system. Immediately behind this, cleaned and/or new ballast is applied to the existing subgrade using a ballast laying device.
- ballast cleaning with all the preliminary work and main work.
- MDZ mechanized maintenance train
- DVS dynamic track stabilizer
- ballast train consisting of ballast self-unloading wagons.
- the track panel is lifted by the mechanical maintenance train and the new ballast is compacted under the sleepers. This process of new ballast feeding, track elevation and compaction is repeated to achieve a ballast bed of the desired height.
- the top picture shows the first work phase of excavating the ballast and placing the ballast while lifting the track grid.
- the ballast is removed with a cleaning chain from under the raised track panel.
- the clearing height is usually 300mm.
- the removed old ballast is screened and sharpened.
- This cleaned ballast is brought back onto the track with a ballast conveyor and distributed with a plow to a maximum initial height of 150mm.
- This maximum initial height is specified by the regulations of various rail infrastructure operators, for example by the French SNCF. According to the regulations, the ballast is compacted immediately afterwards using a stabilization unit, whereby the ballast bed height drops to approx. 130mm.
- a stabilization unit whereby the ballast bed height drops to approx. 130mm.
- new ballast is brought in using a ballast train and distributed using a plough.
- the track grid is then lifted by 80mm ; while tamping the raised sleepers.
- a subsequent stabilization process leads to a settlement of the track grid.
- the third phase of work is a repetition of the second phase of work, with a further raising of 80mm and a settlement of about 280mm.
- the ballast in the track is usually sufficient to carry out a final tamping process in a fourth work phase. However, it may also be necessary to unload new ballast in front of the tamping machine.
- the tamping machine lifts the track panel by 20mm to 25mm into a specified geometry.
- the subsequent stabilization causes a lowering to the original ballast bed height of approx. 300mm.
- the ballast bed is profiled and the ballast grains lying on the sleepers are swept away.
- the object of the invention is to improve the method of the type mentioned above compared to the prior art in such a way that all work can be carried out in a shorter track possession.
- the quality of the compacted ballast bed should correspond to the specifications of the railway infrastructure operator.
- the new process has the advantage that more cleaned ballast can be reused than with the known process.
- This ballast is introduced into the track via the ballast insertion device immediately after cleaning and does not have to be temporarily stored or replaced with new ballast.
- Another advantage is the reduction in tamping, which protects the ballast.
- one pass is also eliminated for the ballast plow and the track stabilizer. Due to this reduction in work processes, fewer personnel are required on the track. This reduces labor costs and contributes to the safety of the track construction site.
- the ballast bed is cleaned at least with a removal height of 300mm with the method according to the invention. This results in no losses compared to the conventional method, with the required compaction quality being achieved with the deep tamping process.
- a further improvement provides that by means of the gravel placing device, gravel is placed for a bedding height of at least 200mm, in particular at least 250mm. This ensures that the original ballast bed height is reached with the remaining lifting operations without impairing the compaction quality.
- the track panel is lifted by at least 50mm, in particular by at least 70mm. This means that only a small amount of lifting is required for the subsequent second tamping process in order to create the specified track geometry.
- the track panel is advantageously lifted in the second lifting process with a lift in a range between 15 mm and 25 mm, in particular in a range between 20 mm and 25 mm. This leaves enough leeway for creating the specified track geometry without loosening the ballast bed unnecessarily.
- the method is further developed by an advantageous deep tamping process in which, after the first lifting process using the deep tamping unit, a first tamping process is carried out in a lower deep layer of the ballast bed with vibrating and tilting tamping tools and a second tamping process in an upper deep layer of the ballast bed with the same tamping tools .
- the track panel is held in position during the tamping process using a lifting unit.
- the efficiency of the method according to the invention is further increased if the tamping process is carried out after the second lifting process by means of a multi-sleeper tamping unit. In this way, the second tamping process is completed at an increased working speed.
- the speed of processing is further increased if the tamping work is carried out with a tamping machine integrated in a cleaning train.
- the cleaning process and the respective compaction process are coordinated with one another by means of a higher-level controller.
- all units are supplied via a common drive carriage of the cleaning train, with an optimized energy supply for the integrated machines.
- Fig. 1 shows the method described above with a layered introduction of the cleaned and / or new ballast 1 in a track 2.
- the ballast 1 located on a planum 3 forms a ballast bed 4 for a track grid 5 of sleepers 6 and rails attached thereto 7.
- a track-bound cleaning machine 8 is used to clean the ballast bed 4 .
- this is only indicated with dashed outlines and includes several machine frames supported on rail undercarriages. Devices and aggregates for processing the track 2 are arranged on the machine frame.
- ballast removal device 10 removes the ballast 1 with a removal height h1 (eg 300 mm).
- This defined removal height h1 extends from the subgrade 3 to be exposed to the lower edges of the sleepers 6 stored in the ballast bed 4.
- the gravel 1 located between the sleepers 6 is also included.
- the ballast removal device 10 comprises a revolving endless clearing chain, which continuously picks up the ballast 1 during forward travel and transfers it to a conveying device for forwarding to a screening plant.
- ballast loading device 11 delivers the cleaned ballast 1 to a ballast loading device 11. Based on a working direction 12, this ballast loading device 11 applies a first layer of the cleaned ballast 1 to the exposed subgrade 3 immediately behind the removal device 10.
- the applied ballast 1 is distributed with a desired first bedding height h2 (e.g. 150 mm) on the planum 3 with a plow 13 .
- the track grid 5 placed on this newly created ballast bed 4 is vibrated by means of a stabilization unit 14 under load. With this stabilization process, settlements of the ballast bed 4 are anticipated. The result is a reduced second bedding height h3 (e.g. approx. 130mm).
- ballast train 15 In the second phase of work, another layer of ballast is poured onto track 2 by means of a ballast train 15.
- a ballast plow 16 preferably designed as a separate machine, distributes the ballast 1 with adjustable plow plates 17. This means that there is enough ballast 1 on and between the sleepers 6 for a first tamping operation.
- a tamping machine 18 provided for this purpose comprises a lifting unit 19 and a tamping unit 20.
- the lifting unit 19 lifts the track panel 5 with a first elevation h4 (e.g. 80mm) to a third bedding height h5 (e.g. 210mm).
- a stabilization machine 21 also known as a dynamic track stabilizer (DGS)
- This stabilizer is either designed as a separate machine or is coupled to the tamping machine 18 .
- the effect of the stabilization unit 14 leads to a compression of the ballast bed 4 to a fourth bedding height h6 (e.g. 205 mm).
- the work steps of the second work phase are repeated in a third work phase, with a third layer of ballast being introduced into the track 2 by means of a ballast train 15 .
- the track grid 5 is first raised to a fifth bedding height (eg 285mm) with a second elevation h7 (eg 80mm).
- a sixth bedding height h9 eg 280 mm.
- the track panel 5 is brought into a specified track geometry with a third lift h10 (e.g. 20mm to 25mm).
- the final position of the track is established after a final stabilization by means of the stabilization unit 14 .
- the ballast bed 4 renewed in this way has approximately the same height as before the cleaning process.
- the disadvantage of this known method is the large number of work steps that are necessary due to the layered introduction of ballast including ballast compaction.
- the cleaning of a ballast bed 4 starts with a cleaning machine 8.
- a lifting unit 9 of the cleaning machine 8 a section of the track panel 5 to be processed is lifted.
- the lifting unit 9 includes roller tongs, which grip the respective rail head of the rails 7 and roll along the rails 7 during a forward movement of the cleaning machine 8 .
- a ballast removal device 10 running with a crossbeam below the raised track panel section picks up the ballast 1 at a predetermined removal height h1 (e.g. 300 mm).
- the ballast is picked up by means of an endless clearing chain that encloses the track panel 5 .
- the clearing chain conveys the removed ballast 1 upwards to a first conveying device (not shown) via a lateral channel. In this way, the ballast 1 is fed to a screening plant arranged on the cleaning machine 8 .
- ballast 1 is cleaned in the screening plant. If necessary, the edges are then sharpened in an impact mill.
- the cleaned ballast 1 is conveyed to the ballast bringing-in device 11 by means of a further conveying device. Falls too little processed gravel 1, new ballast 1 is added. This is carried along in a memory of the cleaning machine 1, for example.
- New gravel 1 can also be carried along with so-called material conveyor and silo units (MFS). These units are rail vehicles coupled to the cleaning machine 8 and are used to accommodate overburden that accumulates during the cleaning of the ballast.
- MFS material conveyor and silo units
- ballast 1 considerably more ballast 1 than before is introduced into the track 2 with the ballast loading device 11 of the cleaning machine 8 .
- the ballast layer smoothed with the plow 13 of the cleaning machine 8 advantageously has a first bedding height h2' of 250 mm, measured from the exposed subgrade 3 to the lower edges of the sleepers 6.
- h3' approximately 230mm
- ballast train 15 new ballast 1 is thrown onto track 2 by means of a ballast train.
- a ballast plow 16 distributes this ballast 1 for a subsequent tamping operation.
- a lifting unit 19 of a tamping machine 18 lifts the track panel 5 with a first lift h4' by advantageously 70 mm.
- a third bedding height h5' of approx. 300mm is thus achieved.
- the track panel 5 is fixed in this raised position in two steps by means of a tamping unit 22.
- a tamping unit 22 is disclosed in AT 522237 A1 by the same applicant.
- the deep tamping unit 22 has a larger range of vertical movement of the tool carrier.
- longer tamping picks 23 are used.
- the tamping tines 23 of the deep tamping unit 22 dip into a lower depth layer of the ballast bed 4 and are placed there in a vibrating manner.
- the upper edges of the pick plates located on the tamping pick ends are at least 100mm below the lower edges of the sleepers 6.
- the vibration is generated by means of a rotating eccentric shaft to which hydraulic auxiliary cylinders are connected. Adjustment movement and vibration can also be superimposed in the respective hydraulic cylinder, with a corresponding control with integrated distance measurement being provided.
- a second compaction step takes place, in which the tamping tines 23 are lowered into an upper deep layer of the ballast bed 4 .
- an auxiliary process is carried out under the action of vibration.
- This upper deep layer lies between the previously compacted lower deep layer and the lower edges of the sleepers 6.
- the ballast bed 4 is compacted over the entire bedding height h5' by means of the deep tamping unit 22.
- a stabilization process then takes place by means of a stabilization machine 21, as a result of which a slightly reduced bedding height h6' is set (approx. 295 mm).
- the final geometry of track 2 will be established in a final work phase.
- the track 2 is processed with the same or another tamping machine 18.
- a lifting/straightening unit 19 lifts the track panel 5 with a slight elevation compared to the specified track geometry. This takes into account the subsequent track settlement during stabilization.
- This second elevation h7' is in the range of 20mm to 25mm and is therefore significantly less than the first elevation h4'.
- the track panel 5 is straightened laterally.
- a tamping unit 20 for the simultaneous tamping of several sleepers 6 reduces the processing time in this work phase.
- This tamping unit 20 is either in addition to the deep tamping unit 22 on the same tamping machine 18 or on a separate tamping machine 18 arranged.
- the same lifting/straightening unit 19 is advantageously used for all lifting steps.
- a stabilization process takes place by means of a stabilization unit 14. This is arranged either in a separate stabilization machine 21 or on a machine frame coupled to the tamping machine 18.
- the new working method is not limited to the track cleaning process presented as an example.
- the method according to the invention can be used for cleaning trains with integrated tamping machines 18 and stabilization machines 21 and optionally plow blades 17 .
- the process can also be used for cleaning switches or replacing switches.
- ballast is placed at once up to a bedding height h2' of 250mm and then compacted in one pass with deep tamping, normal tamping and stabilizing.
