Definitions

  • the present invention relates to a method for producing a carriageway for rail vehicles, in particular a so-called fixed carriageway, in which the rails are laid, aligned and then fixed in particular in sections.
  • Solid carriageways are used today mainly for high-speed lines. They are manufactured, for example, by pouring the sleepers supporting the rails into a layer of concrete, which is produced on a previously made lower base layer by means of suitable formwork.
  • the tracks are aligned in a concrete trough and fixed in their position by means of spindles and straightening screws. The trough is then filled with concrete to create the base course for the tracks. After the concrete has hardened, the solid roadway is ready.
  • the rails change their length when the temperature changes due to fluctuations in the ambient temperature or due to solar radiation.
  • the change in length can be several centimeters. Since the sleepers are connected to the rail via the rail fastening, these changes in length are transferred to the sleepers, which are can shift until the roadway concrete has hardened, which results in detachments between threshold concrete and grouting concrete. Temperature fluctuations can also occur before the concrete is poured if the track is already aligned. This means that the alignment must be repeated, which is a considerable additional effort.
  • the invention has for its object to develop a method of the type mentioned so that these problems do not occur.
  • an influence of the change in the ambient temperature and the solar radiation should be reduced as much as possible.
  • This object is achieved in that the rails are kept at a fixed temperature at least temporarily and in sections during the manufacture of the carriageway, at least up to a tolerable fluctuation range.
  • the rails are specifically heated to a temperature that is higher than the environment.
  • the heating takes place to a temperature which is in the range which is caused by fluctuations in the ambient temperature and by Maximum sun exposure can be achieved.
  • the rails can be heated to a temperature between 35 ° C and 50 ° C. In cool weather the temperature can be correspondingly lower, in the hot season correspondingly higher. Sunshine and temperature changes can only cause minor changes in the rail temperature.
  • the measures described are preferably carried out until the rails are adequately fixed, since the rails can then no longer change their length. In principle, it is also sufficient to carry out the measures only after the track has been set up. This simplifies the procedure and saves costs. Simplification and cost savings are also achieved in that the measures are carried out section by section. For example, a section corresponding to a daily output can always be treated, for example between 300 m and 600 m.
  • the rails can be heated electrically. Another possibility is to heat the rails by electromagnetic induction. Both can be carried out with relatively little effort and leads to a largely uniform heating of the rails.
  • the rails are covered at least temporarily and in sections with a cover made of a radiation-reflecting material during the manufacture of the roadway.
  • material webs that can be rolled up and unrolled are used for covering. This simplifies the application of the cover and the webs can be rolled up and used again after use.
  • the material webs are designed to be reflective on both sides. This has the advantage that the webs can be used on both sides. In addition, this enables rolling up and down in different winding directions, so that the roadway is produced continuously in one direction can, without the material web having to be wrapped or wound against the working direction.
  • Films made of a reflective material can be used as the material web. However, it is also possible to use foils that are coated with a reflective material. In all cases, aluminum can be used as the reflective material.
  • the material in addition to the rails, covers the entire track and in particular the entire track and the hardenable layer.
  • the cover also takes on the function of covering the fresh concrete, which is common in concrete construction, to prevent wind cracks and drying out too quickly. A separate cover and a corresponding further manufacturing step are therefore unnecessary.
  • the two rails can each be covered by a separate cover.
  • a common covering for the entire track in particular including the curable layer, can also be provided. Applying a common cover is relatively easy, while individual covers are easier to handle. Material can also be saved if necessary.
  • the cover is applied after the track installation and alignment and before the curable layer is introduced, and is removed in sections during the introduction and / or post-compaction and then applied again.
  • the rails are therefore practical during the entire production and are only exposed for a relatively short period during which the curable layer is introduced or densified.
  • the exposed track section shifts according to the progress of the hardenable layer.
  • a first material web deposited on the tracks is rolled up as the curable layer progresses, and a second material web is placed on the tracks in the area of the curable layer that has been introduced. This allows continuous work in a clever way with only a small uncovered track area.
  • the rails are at least partially reflective.
  • the heating of the rails by solar radiation is reduced, so that the temperature fluctuations of the rails and thus their changes in length can be kept small.
  • the rail temperature can therefore also be kept within a tolerable fluctuation range by this measure alone or in conjunction with other measures.
  • the rails can be colored, in particular white, or coated. This is simple and effective.
  • FIG. 1 shows a cross section through a solid carriageway with a rail cover
  • FIG. 2 shows a plan view of a solid carriageway with rail cover and Fig. 3 shows a cross section through part of a solid track with another rail cover.
  • Fig. 1 shows a cross section through a fixed carriageway being manufactured with two rails 1 which are arranged on sleepers 2 and together with these form a track 3 which is to be laid in the fixed carriageway.
  • the sleepers 2 are supported in a concrete trough 4, in that at least some of the sleepers 2 are placed on the bottom 6 of the trough 4 by means of rotatable spindles 5.
  • Spindles 5 also serve to align the track 3 in height and the mutual height of the rails 1.
  • directional screws 7 are provided for the lateral direction of the track 3, which act on both sides of at least part of the sleepers 2 and are attached to side walls 8 of the Support troughs 4.
  • the trough 4 is placed on a lower base layer 9, in particular a hydraulically bound base layer, which is arranged on a frost protection layer 10, which in turn is applied to the substrate 11.
  • the trough 4 is filled with concrete to form a base layer 12 such that the sleepers 2 are poured into the upper base layer 12.
  • the track 3 is covered with a material web 13, which is only shown in broken lines in FIG. 2 and extends in the longitudinal direction of the track 3 and is so wide that, in addition to the track 3, the concrete layer 12 in the trough 4 is also covered.
  • the material web 13 consists of a radiation-reflecting material or is coated with such a material, preferably on both sides.
  • the substrate 11 is first prepared, then the frost protection layer 10 and the lower base layer 9 are applied.
  • the trough 4 is then placed on the lower base layer 9.
  • the track 3 is then laid in the trough 4 and, after alignment via the spindles 5 and straightening screws 7, its position is fixed and the track 3 is covered with a radiation-reflecting, rollable material web 13. A change in length of the rails 1 under the material web 13 is thus avoided or at least largely restricted. It is not necessary to realign the track 3 because of displacements due to the heating of the rails 1.
  • the material web 13 is now rolled up at one end, so that a section 14 of the track 3 is exposed.
  • concrete is poured into the trough 4 to form the upper base layer 12.
  • a second material web 13 ' is placed over the section 15 of the trough 4 which has already been poured with concrete.
  • a material web 13 'present as a wrap is preferably used and is processed in accordance with the work progress. This is illustrated in Fig. 2. A corresponding procedure can be followed when the concrete layer 12 is compacted again.
  • the track 3 is always uncovered only in a relatively small working area 14. There is therefore no disadvantageous track heating and, as a result, track lengthening.
  • the newly placed second material web 13 After completion of the upper base layer 12, the newly placed second material web 13 'remains on this and the track 3 until the upper base layer 12 is sufficiently hardened to absorb a change in length of the rails 1.
  • each rail 1 has its own cover 13, which - as shown in Figure 3 with a solid and dashed line - narrower or can be placed further around the rail 1.
  • the two separate rail covers 13 can be laid in the same way as described above. For the rest, the method using two separate rail covers, which only comprise the rails themselves, corresponds to the previously described method.
  • the method according to the invention described largely prevents track heating during the manufacture of the solid carriageway. Sun rays and heat rays from the ambient heat are reflected by the material web 13, 13 ', thereby protecting the track against heating.
  • the double-sided coating of the material web 13, 13 ' also prevents the rails 1 from cooling and thus shortening them. A realignment of track 3 and one
  • the method according to the invention can also be used in other production methods for producing a solid roadway, for example in troublesome production methods.
  • Aluminum in particular can be used as the reflective material.
  • commercially available foils can also be used for covering.
