Definitions

  • This invention is concerned with maintenance to a railway track, particularly within the narrow space of a buried tube of a subway, especially if the tube dimensions are adapted to contain merely a single track.
  • the invention is illustrated by way of replacing the railway track within the buried tube of a subway, it will be appreciated that the field of application is broader and is generally applicable to a railway and its maintenance.
  • a tube containing a single track offers little or no space aside the track, since the cross sectional tube dimensions are adapted to tightly enclose the track, its foundation, the train moving along the track and the energy and auxiliary supplies.
  • the cross sectional tube dimensions are adapted to tightly enclose the track, its foundation, the train moving along the track and the energy and auxiliary supplies.
  • the supply, installation and discharge of the relatively large and heavy parts is difficult and time consuming since all material, equipment and personnel is forced to use the same tube.
  • train traffic may be disabled for only a short period, e.g. three hours during the night, the daily progress of replacement of the track is very limited to e.g. one or two meters.
  • the object of the invention is to improve the processing of a railway track renewal by proposing to replace a longitudinal part of the track by a temporary auxiliary track which is preferably designed such that it contains means to adapt or adjust the auxiliary track to the local conditions, e.g. one or more of rail width, (horizontal) curvature, level, cant, alignment, such that said auxiliary track becomes part of the course of the original track and the train traffic can maintain its normal route and speed.
  • a temporary auxiliary track which is preferably designed such that it contains means to adapt or adjust the auxiliary track to the local conditions, e.g. one or more of rail width, (horizontal) curvature, level, cant, alignment, such that said auxiliary track becomes part of the course of the original track and the train traffic can maintain its normal route and speed.
  • the invention is further eloborated by way of a non-limiting embodiment, refering to the enclosed drawing.
  • Fig. 1 shows partly a cross section of a subway tube to which the invention can be applied.
  • it contains spaced apart, parallel, train wheel bearing rails of the track that are mounted by rail mountings on wooden sleepers, embedded in concrete having a central recess containing gravel.
  • Conductor rails on insulators, between and aside the train rails provide electrical driving power supply to the train.
  • the train rails can be of the so called bullhead type, i.e. they are syzametricaily shaped such they can also be used in inverted position after the original rail head is worn out. It will however be appreciated that the invention is also applicable to different rail types and rail connections and also to different sleeper and power supply types.
  • a temporary bridge part or adjustible construction 2 is provided, as illustrated in cross section in fig. 1 and 2, in sectional side view according to line A-A and B-B in fig. 3 resp. 4 and in sectional top view according to line C-C in fig. 5.
  • the construction 2 is shown during the operation of track replacement.
  • Fig. 3, 4 and 5 show only a longitudinal part of the construction 2 at the location where it connects to the original (to be replaced) track.
  • the original track is at the left hand side of line Z (fig. 3-5).
  • the construction 2 at its opposite end connects to the original track or new track.
  • Construction 2 is provided by two parallel rigid longitudinal beams 3 at both sides of the centre line A-A of the track, between temporary rails 5 of low height.
  • the beams 3 and rails 5 are mutually connected by a plurality of cross beams 4 spaced along their length.
  • These cross beams 4 have an adjustable length, such that the mutual spacing between beams 3 and rails 5 can be adjusted. This is important not only for adjustment to the ends of the original track to which this construction 2 is connected, but also to bend the rails 5 according to the (horizontal) curvature (e.g. a radius of 60 m) of the original track it temporarily replaces.
  • the bending stiffness of the beams 3 is sufficiently high such that they form the proper solid "backbone" to horizontally and vertically bend the rails 5.
  • the construction 2 offers space to apply a check rail at the inner rail 5.
  • the cross beams 4 provide some kind of sleepers, adjustable in length.
  • the fastening of the rails 5 and the conductor rail 6 to the relevant cross beam 4 can as an alternative be adjustable or repositionable, such that the cross beams 4 can have a fixed length.
  • the rail 5 can be clamped to the beam 4 such that it can be shifted along beam 4 after loosening the clamps.
  • the central cross beam 4 bears the (negative) conductor rail 6 which also belongs to construction 2.
  • Construction 2 is provided with a plurality of longitudinally spaced supports 8, preferably having an adjustible length, e.g. as telescopic rods or tubes. As shown, two arrays of these supports 8 are provided at both sides of the track centre line, also allowing for adjustment of the cant or vertical alignment. Preferably, these supports 8 are designed to completely support the construction 2 and a train bearing on the rails 5. The construction 2 behaves like a unitary object.
  • Construction 2 can be provided with running wheels (not shown) or skates or equivalent means such that it can conveniently be moved over the substrate in longitudinal direction, e.g. after being jacked up. Or it can be provided with equipment with lifting points, such that construction 2 can be hoisted to the tunnel roof. It can also be provided with integrated walkway boards to provide an (emergency) walkway.
  • the spacing between the cross beams is such that the old or new sleepers can be nested between these cross beams 4.
  • the dimensions of the rail 5 and beam 4 are such that the top of rail 5 is level with the top of the corresponding rail 1 of the original track and the new track.
  • the original rails 1, central (negative) conductor rail 10 and sleepers 9 are removed over a predetermined length, preferably substantially equal to the length of the construction 2.
  • said length corresponds to a plurality of a length part that can be replaced during a single daily shift when applying the prior art method.
  • said length corresponds to a standard rail length, which is at least 10 m.
  • the original lateral (positive) conductor rail 11 remains in place.
  • the construction 2 is installed and its rails 5 are connected to the ends of the existing rails 1 and its central conductor rail 6 is connected to the ends of the existing central conductor rail 10 and the required alignements of the components of the construction 2 are carried out to allow safe railway traffic.
  • construction 2 bridges the gap in the original track due to removal of the original rails 1, central (negative) conductor rail 10 and sleepers 9 over said predetermined length.
  • Supports 8 are located in a previously with gravel filled recess 12 in the concrete rail embedment 13.
  • the construcion 2 is removed (e.g. rolled forward or backward over at least a distance corresponding to its length) and then the concrete embedment 13 is removed and finally the construction 2 is replaced to allow safe railway traffic.
  • the construction 2 is removed, and then the new rails and the new central conductor rail are installed such that the track replacement for this length part is completed and safe railway traffic in this length part is permanently provided. Then the construction 2 will be used to process a subsequent length of the track, wherein the steps according to day 1 - 5 can be subsequently repeated.
  • the invention also covers embodiments obtained by removing one or more features of the above disclosed embodiment, or replacing it by a functional equivalent.
