Definitions

  • the invention relates to the basic construction of a railway system with central core shoring, the Application is especially for slow travel routes in the course of maintenance offers double and multi-track routes.
  • a formation and frost protection layer is often used to maintain railway lines installed under the track ballast.
  • Two-track and multi-track routes are usually initially a track, the track 1, dismantled and drive on the other track (track 2).
  • a middle core shoring is necessary in the dismantled state of track 1.
  • the central core shoring is expensive according to the prior art as sheet pile or designed as a screed wall and is generally in the path axis.
  • At the Installation and dismantling of such a center core shoring is the blocking of the operating track necessary.
  • the space required for the technology to be used compels to this - often organizationally and technically complex - Measure.
  • the invention thus uses the sliding knife shoring, which is a principle Known for the knife-layer tunnel distribution, but also for the trench distribution is. The associated technical expenditure is also considerable.
  • the aim of the invention is to reduce these disadvantages of the prior art at low cost remove.
  • the task here is to develop a central core shoring, its System can be used across tracks. This object is achieved through the features of the claims 1 and 5 solved.
  • the central core shoring is carried out so that the construction limit lies outside the pressure range of the traffic loads of the operating track and on this a temporarily effective support structure is erected, which then Construction of the second track acts as a shoring.
  • the supporting structure preferably consists of geosynthetic reinforced earth. At this center core shoring from reinforced earth can a gravel mount must be attached. If central drainage is necessary are these introduced according to the invention in front of or in the support structure; the same applies to supply lines.
  • the deep drainage, e.g. B. executed as gabions prefers a stable form, so that it is an additional abutment of the central core shoring forms.
  • the stable shape allows the construction of the formation and Frost protection layer of track 2 a clear separation of different materials, namely between the filter material of the deep drainage and the base layer material the formation / frost protection layer. At the same time, it ensures that the formation / frost protection layer of track 2 is installed against a fixed abutment can be, which ensures a high quality of installation.
  • the invention can be of basically the same design even in the case of multiple tracks Find routes application.
  • the invention has the particular advantage that the possible integration of horizontally continuous, transverse to the shoring Tension members the stability of the entire track body is sustainably increased.
  • the solution according to the invention compared to the prior art is much cheaper.
  • FIGS. 1-4 The invention is described below using two exemplary embodiments (FIGS. 1-4) and the representation of the basic construction phases (Fig. 5; 6) explained in more detail. moreover An embodiment variant of the design of the support system (Fig. 7) is disclosed.
  • Fig. 1 shows the invention including deep drainage with gabion wall; Details of this can be found in FIG. 2. It can be seen that the wall of the Temporary support structure 1 - preferably made of geoplastic reinforced Earth - outside the pressure range of the traffic loads - cf. Pressure propagation line 2 according to service regulation 836 of Irish Bahn AG. The deep drainage 3 with gabion wall is inserted in the middle; the formation protection layer In the exemplary embodiment, 4 has a gradient of 5 percent.
  • the gabions 5 is square in cross section, e.g. B. 0.50 x 0.50 m and about 3 m long. she is lined with nonwoven fabric 6 and contains this in the gravel sand 7 (preferably 2/16) horizontal drain pipe 8 (DN 200).
  • the space between support structure 1 and gabions 5 (distance approx. 0.1 m) is also filled with gravel sand 7.
  • the support structure 1 is wedge-shaped.
  • the lower integration length of the reinforcement textile is 9 approx. 1 m; above it is about friction within the formation protection layer 4 involved.
  • the reinforcement textile 9 is also by floor nails 11, which are introduced at a distance of approx. 1 m.
  • the wall of the support structure 1 is from the beginning and permanent via a stabilizing basket 12 from a reinforcing steel bearing mat using stabilizing bar 13 (also 1 Pieces / meters).
  • Fig. 3 is an embodiment of the invention with an off-center deep drainage 14 shown; Details are shown in Fig. 4.
  • the essential to the invention The structure of this variant is basically analogous to that described above. Dispensing with the stable gabion wall requires a larger one Technological care in the design of this drainage, on the other hand, is eliminated the cost of the gabion elements.
  • FIG. 7 An embodiment variant of the design of the support system is shown in FIG. 7.
