Definitions

  • the invention relates to a mobile low noise barrier on a railroad of the type specified in the preamble of claim 1.
  • This noise barrier comprises arranged outside the control clearance, stable individual foundations in a predetermined grid spacing, as an abutment for a support of the noise barrier elements.
  • the holder comprises a vertically orientable panel carrier that can be placed just outside the control clearance or its boundary line.
  • the panel carrier is held on a spacer, which is supported on the individual foundations. In this arrangement, it is provided to mount the spacer carrier foldable to bring the noise protection wall element in a distant position from the closer track area.
  • the spacer and the noise protection wall element are pivoted arcuately about an axis arranged on the foundation, so that the noise protection wall element assumes a substantially horizontal position facing away from the track.
  • the DE 10 2011 013 145 A1 discloses a modular, pivotable soundproof wall for use on railroad tracks.
  • the soundproofing wall consists of several elements, which are on a suspension with two joints with vertical axes, which are attached to the suspension.
  • two consecutive noise protection wall elements are mounted on a suspension together, so that for pivoting individual noise barrier elements must be removed and the other noise protection wall elements are to pivot together, which is possible only with considerable effort and often can lead to mechanical stresses of the system.
  • the present invention has for its object to provide a mobile low noise barrier to a rail of the type specified in the preamble of claim 1, which has only a small footprint and is easy to handle.
  • the support device is established outside of that portion of the rail track which must be readily accessible to processing machines such as ballast tamping machines.
  • both the noise protection wall is pivoted about one of the joints, as well as the support device to the other joint, so that the noise protection wall elements reach into an area above the foundation of the support device. It is particularly advantageous that the noise barrier elements can assume a vertical position in this position.
  • the invention is of particular use for gravel railway lines, it is not limited to these, but can also be used on fixed carriageways. By the invention, the passage of vehicles with excess width (work or maintenance vehicles) is possible.
  • the second joint is arranged at the lower end of the noise protection wall element and the noise protection wall element against a pivoting movement of the carrier can be pivoted.
  • the joint it is possible to pivot the noise protection wall element against the direction of rotation of the carrier, so that the noise protection wall element is vertically upwards or through further pivoting bears against the carrier.
  • the second joint it is also possible to arrange the second joint at a distance above a support surface of the noise protection wall element. Such an embodiment is particularly advantageous in an uneven edge area next to the track, since the second joint does not come into contact with the upper edge of a ballast track or the like.
  • the noise protection wall element about the axis of rotation of the second joint in the same direction is pivotable as the carrier about the pivot axis of the first joint. In this way, the noise protection wall element is foldable towards the carrier and can be applied to this.
  • the noise protection wall element is pivotable about the axis of rotation of the second joint so far that the noise protection wall element abuts the carrier in the position away from the nearer track area substantially reduces the required room height of the noise protection wall in the position away from the nearer track area.
  • devices are provided, by means of which the carrier device can be arrested in the position of the noise protection wall element remote from the closer track area and can be locked to the carrier in the track-near position of the noise protection wall element.
  • the support device comprises two at a distance one above the other and parallel to each other arranged carriers, which are each provided with first and second joints. This results in a parallelogram-like mounting of the noise protection wall element, by which a secure guidance of the noise protection wall element is ensured with respect to the vertical orientation.
  • the support device comprises a pile, with which the at least one carrier is connected by means of the first joint.
  • the support device may comprise a foundation block to which the carrier is connected by means of the first hinge.
  • the noise barrier elements consist of an electrically non-conductive material.
  • the support device may consist of a statically resilient, electrically non-conductive material, in particular of a glass fiber reinforced plastic or high performance concrete.
  • the Fig. 1 shows a schematic representation of a rail track 1, in which on a ballast track 2 railway sleepers 3 are arranged with rails 4 mounted thereon and form a track 5.
  • a low noise protection wall element 6 is supported next to the track 5 or preferably kept hovering just above it.
  • a noise protection wall is formed, which extends parallel to the longitudinal direction of the track 5 and is arranged directly outside a predetermined clearance profile.
  • the noise protection wall element 6 extends vertically above the ballast superstructure 2 and is fastened to carrying devices 7 which are arranged on the side of the noise protection wall element 6 facing away from the track 5.
  • the noise protection wall element 6 is inclined to the track 5 at an angle of up to 10 ° (for example, 5 ° to 10 °).
  • Each noise protection wall element 6 is provided with at least one support device 7 near its longitudinal end relative to the ends.
  • the in Fig. 1 The vertical section shown only shows a support device 7.
  • the support device 7 comprises a support 8 and in each case a post 10.
  • the pile can also be provided a plate.
  • the carrier 8 is fixed at one end by means of a first hinge 9 at the upper end of the pile 10, wherein the first joint 9 has a horizontal, parallel to the track 5 extending pivot axis 11.
  • the carrier 8 is connected by means of a second articulation 12, which has a rotation axis 13, with the noise protection wall element 6, wherein in the embodiment of the Fig. 1 the second hinge 12 is spaced from a lower surface 14 of the noise barrier wall member 6.
  • the pile 10 is aligned in the exemplary embodiment to a vertical axis V. In the in Fig. 1 shown position, the noise protection wall element 6 is fixed relative to the support 8 and thus locked.
  • the support 8 can be pivoted about the pivot axis 11 according to arrow 15, whereby the noise protection wall element 6 is raised, which is represented by an arrow 16 in principle, wherein the noise barrier wall element 6 relative to the carrier 8 to the arrow 15 opposite pivotal movement about the axis of rotation 13 may perform, so that the noise protection wall element 6 is brought into a vertical orientation or retains this.
  • Fig. 2 If the arrangement is shown in a position of the noise protection wall element 6 removed from the nearer track area.
  • the carrier 8 extends vertically above the Post 10.
  • the noise barrier wall element 6 also extends vertically, so that only a minimal space is required next to the track 5, to bring the noise barrier in the remote position.
  • the support 8 does not have to be aligned vertically; a position of the support 8 at an angle ⁇ to the vertical axis V of a maximum of 30 ° is also possible.
  • the carrier 8 is fixed relative to the pile 10, that is, it is a lockable support device 7. Another possibility is, starting from the position according to Fig.
