Definitions
- the invention relates to a method for converting a ballast track in a fixed lane.
- the increasing traffic density on the railway networks calls for ever shorter interruptions for the maintenance and renewal of the roadways.
- the method described above is not suitable for a conversion in short stretches with short interruptions of the trafficability.
- the present invention seeks to propose a method for converting a ballast track in a solid lane, the be carried out on short stretches and consequently in relatively short periods of time, such that the track between these periods is passable.
- This solution according to the invention has the particular advantage that by removing ballast in a section extending over several thresholds, space is created for the erection of a fixed roadway without the position of the rails having to be changed for this purpose. After inserting the supports, the track is already passable again, so that the route in question does not have to remain locked until all process steps have been carried out. Since the supports are adjustable, no additional adjustment must be installed for the exact vertical adjustment of the rails.
- FIG. 1 shows as a starting state of the method arranged in a concrete trough 1 ballast track with lying in a bed of ballast 2 sleepers 3, for example wooden sleepers and thereon fastened by means of fastening devices 4 rails 5.
- the threshold distance is for example 60 centimeters.
- FIG. 2 a state is shown in which removed in a section 6 a part of the ballast 2 was, so that in this section 5, the underside of the sleepers 3 no longer rests on ballast 2, but hang the sleepers 3 on the rails 5.
- the length of the section 6 is chosen so that the rails in this section practically do not sag.
- thresholds 3 were first pushed together in the state shown four of them to one end of the track section 6, after previously the fasteners 4 have been solved only so far that the sleepers 3 along the rails 5 to this suspended hanging.
- FIG. 3 shows a state in which within the route section 6 one of the unchanged resting in the ballast 2 threshold 3 right in the picture to the collapsed thresholds left in the picture reaching working section 7 was completely freed and cleaned to the bottom of the concrete trough 1 from the gravel.
- the removal of the ballast can be done by mechanical or pneumatic means, such as a suction device. In principle, it is also possible to completely remove the ballast in a single operation, but the stepwise procedure described has the advantage that after pushing together or removing the thresholds 3, the remaining ballast is much more accessible.
- At both ends of the working section 7 were temporary formwork used to retain the remaining ballast 2, of which only the formwork 8 is visible in the figure.
- FIG. 4 is to recognize a situation in which a prefabricated threshold unit, consisting of a concrete slab 9 with four in the example arranged on concrete blocks 10 fastening devices 11 was deposited for the rails 5 between the rails 5 on the ground.
- the inventive method is not limited to the illustrated threshold units, but can also be performed with single block sleepers or sleepers with two attachment devices, one for each rail. Since the concrete slab 9 with its shorter side between the rails 5 place, could also this drop the concrete slab 9 without spreading the rails 5 done.
- FIG. 9 Reference is made, which is a threshold unit consisting of a concrete slab 9 with four arranged on concrete blocks 10 fastening devices 11 in perspective in one opposite FIG. 4 enlarged scale shows.
- the concrete blocks 10 are inserted with the interposition of rubber shoes not visible in the figure in the concrete slab 9.
- the rubber shoes for example, as in the patent CH695698 may be shown formed and between the rubber boot and the bottom surface of the concrete block 10 may each be arranged an elastic insert.
- recesses 12 are arranged, whose function later in connection with FIG. 5 is described.
- a drainage channel 13 In the middle of the concrete slab 9, a drainage channel 13 to be arranged parallel to the rails can be seen.
- threaded sleeves 14 are provided for temporary screwing not shown, supported on the ground screws to allow the concrete slab. 9 to raise, to position exactly vertically and to hold in the vertical position to the desired early strength of the grouting concrete 24 described below.
- 15 laying sleeves are referred to, which may also be formed as threaded sleeves and serve to screw in lifting aids such as eyebolts.
- the concrete slab 9 was opposite the position of FIG. 4 rotated 90 degrees, lifted and fastened with the fasteners 11 to the rails 5.
- the concrete slab 9 is initially positioned at a distance above the ground on the rails 5.
- two supports 17 are placed on the ground in such a way that they come to lie in the recesses 12 of the concrete slab 9 fastened to the slips 5, without touching the concrete slab 9.
- the recesses 12 allow adjacent concrete slabs 9 to be placed very close to one another.
- the FIGS. 10 and 11 show a designated 17 as a whole support.
- a conical concrete body 18 forms a base on which a first plate 19 rests, having on its underside a recess in which the top of the concrete body 18 fits, so that the plate 19 is positioned exactly on the concrete body 18 and can not slip sideways ,
- a support plate 20 is supported by spindles 22. By turning the spindles 22, the distance between the plates 19 and 20 is adjustable.
- cams 21 are arranged, which serve to receive heads of hook bolts, with which provisional rail fasteners are connected to the rails 5.
- a arranged on the support plate 20 fork 23 is used to attach a lateral adjusting spindle 16, as in the FIGS. 5 to 7 are shown.
- FIG. 6 shows the situation of FIG. 5 in a cross section.
- the supports 17 can be seen, which extend into the lateral recesses 12 of two adjacent in the track direction of concrete slabs 9. If the track in this situation must be temporarily passable by trains, 8 more supports 17 can be installed in the free area between the concrete slab and the formwork, which absorb the loads.
- FIG. 7 shows the situation after pouring two concrete slabs 9 with a possible dwindle-free grouting concrete 24, for example from the company Concretum or equivalent.
- the threaded spindles with which the concrete slab 9 is held in its vertical position, are unscrewed from the threaded sleeves 14.
- the units consisting of the upper plates 20 and the lower plates 19 are removed by first of all bringing the upper plates 20 closer to the lower plates 19 by turning the spindles 22 and then moving the units from the into the Roadway remaining concrete bodies 18 are removed.
- the track rests on the fastening devices 11 and the sleeper blocks 10 can sink freely under a train journey with respect to the concrete slab 9.
- the adjusting spindles 16 are still removed.

Das vorangehend beschriebene Verfahren eignet sich nicht für einen Umbau in kurzen Streckenabschnitten mit kurzen Unterbrüchen der Befahrbarkeit.The increasing traffic density on the railway networks calls for ever shorter interruptions for the maintenance and renewal of the roadways. The method described above is not suitable for a conversion in short stretches with short interruptions of the trafficability.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Umbau eines Schottergleises in eine feste Fahrbahn vorzuschlagen, das auf kurzen Streckenabschnitten und folglich in verhältnismässig kurzen Zeitabschnitten durchführbar ist, derart, dass das Gleis zwischen diesen Zeitabschnitten befahrbar ist.Based on this prior art, the present invention seeks to propose a method for converting a ballast track in a solid lane, the be carried out on short stretches and consequently in relatively short periods of time, such that the track between these periods is passable.
Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Massnahmen gelöst.This object is achieved according to the invention by the measures specified in the characterizing part of
Diese erfindungsgemässe Lösung hat insbesondere den Vorteil, dass durch das Entfernen von Schotter in einem über mehrere Schwellen reichenden Abschnitt Platz für das Errichten einer festen Fahrbahn geschaffen wird, ohne dass dazu die Lage der Schienen verändert werden muss. Nach dem Einbringen der Stützen ist das Gleis bereits wieder befahrbar, so dass die betreffende Strecke nicht bis zur Durchführung aller Verfahrensschritte gesperrt bleiben muss. Da die Stützen verstellbar sind, müssen zum exakten vertikalen Justieren der Schienen keine zusätzlichen Justiermittel eingebaut werden.This solution according to the invention has the particular advantage that by removing ballast in a section extending over several thresholds, space is created for the erection of a fixed roadway without the position of the rails having to be changed for this purpose. After inserting the supports, the track is already passable again, so that the route in question does not have to remain locked until all process steps have been carried out. Since the supports are adjustable, no additional adjustment must be installed for the exact vertical adjustment of the rails.
