Definitions

  • the present invention relates to a method for producing railways, in particular so-called fixed lanes, at which built a substructure and placed a track on the substructure, absolutely aligned with geodetic means in relation to a fixed point field and is fixed in its aligned position.
  • the present invention relates to a measuring device for Use such a procedure.
  • the course of the track must be the specifications according to the prescribed accuracy requirements be adjusted.
  • the routes, the gradients and the Elevations of the rail in the case of curved layers are marked out with geodetic means.
  • the requirements the homogeneity of the track i.e. the relative position difference at a predetermined distance from successive track points be fulfilled.
  • the invention is therefore based on the object of a method of the beginning Specify the type mentioned, which also higher requirements can meet the homogeneity of the track and still be the best possible Adaptation to the given route allows. Moreover is the object of the invention, a measuring device for To indicate use in such a procedure.
  • the first-mentioned task is solved in that according to the geodetic Alignment remaining differences in location in a given Distance between successive track points using a relative measurement method determined and disregarding the geodetic Specifications are corrected at least so far that the relative track position has a required accuracy.
  • the required homogeneity can thus be achieved by the method according to the invention the track position even with high requirements, such as those on railroad tracks for high-speed operation, especially fixed Roads that are set are met. It may be the absolute geodetic default values within the tolerance range changed. Still remains because of the previous geodesic Alignment of the track and the minor made Corrections based on the relative measurement adapting to those on the Defined alignment is maintained.
  • An essential thought The invention therefore consists in the homogeneous course of the track according to location and height over the absolute geodetic references in the location and To provide height network. Network inaccuracies and unavoidable deviations when transferring stakeout values with geodetic means are balanced.
  • the method according to the invention thus fulfills the contradictory ones Demands for the best possible adaptation to geodetic specifications and homogeneity of the lines.
  • the method according to the invention is inexpensive and can be done with a small workforce be performed. Depending on the requirement, the procedure can be simple mechanical means or automated, with sensors and computing technology be performed.
  • the method according to the invention can also as part of a progressive manufacturing process a solid roadway can be used.
  • the absolute and the relative alignment of the track position can both in Regarding the lateral position as well as in relation to the height of the track be performed.
  • An implementation for all parameters is preferred the lines.
  • the absolute alignment of the track position can be determined by geodetic Means also performed with less than maximum accuracy become. However, it is preferred to use the absolute alignment as much as possible Perform accuracy. This has the advantage of making corrections in relative alignment to produce the homogeneity of the Track position can be kept low.
  • a measuring device is preferably used to carry out the relative measuring method used the at least three, preferably four, in particular identical elements to each other, each comprising a base body include, which by means of releasable fastening devices in one right angle to the reference rail is attached to this and a position measuring device, in particular has a scale with which the Arrow height to one over all elements, each at the zero point of the Position measuring device of the rearmost and the foremost element placed Tendon, i.e. the deviation of the chord from the zero point of the position measuring devices of the middle elements and with each The target value is compared, on the basis of which arrow height, if necessary the track position is corrected.
  • Such a measuring device is particularly simple in construction and advantageous in use.
  • this measuring device does not require Accessibility of the track to be aligned. You can therefore also with the Production of solid roadways are used, in which the Homogeneity in the routing before concreting by means of the To produce straightening and fixing devices and that Track is to be fixed in this position.
  • the measuring device can also advantageously be moved around fixing devices so that these are not an obstacle to measurement. So it's not free mobility required in the track. The necessary personnel deployment is also used this measuring device low.
  • this measuring device when using this measuring device, in particular one appropriately tensioned flexible connection can be used. It is but also possible to use a laser beam or an optical axis and determine the measured values by scanning. This can cause a fast, automatic and very accurate measurement can be achieved. moreover it is possible to save the measurement data.
  • the elements of the relative measuring device are preferably first of all in particular by means of a reflector attached to the elements, geodetically aligned and thus the track position to the respective Default set up before the relative measurement is carried out and if necessary, by appropriate adjustment of the track a homogeneous Track position is made.
  • a reflector attached to the elements
  • These elements can also be used for the geodetic alignment of the Track can be used.
  • the homogeneity of the track position i.e. the so-called internal homogeneity of the track, checked and corrected if necessary.
  • the elements are preferably spaced about 2.50 m apart positioned. This means that a distance of 5 m can be bridged for three elements and thus regulates the required accuracy from +/- 2 mm to 5 m Track can be easily guaranteed. However, four are preferred Elements used, i.e. bridged 7.50 m.
  • each Element used twice for arrow height determination and correction. This makes the corrections on each element advantageous kept as small as possible and increased accuracy.
  • the second object is achieved with at least one measuring device three, preferably four, in particular identical elements, which each comprise a base body, which is by means of detachable fastening devices at a right angle to the reference rail of the respective Track can be attached to this and a position measuring device, in particular has a scale with which the arrow height to an over all elements placed, each at the zero point of the position measuring device foremost and rearmost element placed tendon, i.e. the deviation the chord from the zero point of the position measuring devices of the middle one Elements can be determined and compared with the respective target value.
  • the elements preferably have a profile, in particular a hollow box profile, as the base body whose dimensions are temperature-independent and on which preferred a holder for a reflector is provided.
  • Means are also preferably provided on the elements which the distance between reflector and reference rail is adjustable. The measuring accuracy can be increased and guaranteed in the long run become.
  • an increase measuring device is provided. With that at Position and height measurement simultaneously the cant, i.e. the relative Height of the two rails to each other, checked and if necessary Getting corrected.
