Definitions

  • the present invention relates to an under-ballast damping device, which has been specifically designed for railroads.
  • trains generate a comparatively high level of noise, due to vibrations propagating either directly to the underlying ground through the train framework, or being indirectly propagated through the rail supporting constructions.
  • the vibrations generated by running trains transmit great stresses to the adjacent structures and, moreover, provide a high acoustical pollution.
  • the aim of the present invention is to provide such a vibration damping device, which is greatly improved with respect to prior like devices or systems.
  • a main object of the present invention is to provide such a flexible vibration damping device which can be used for different types of railroad lines, tramways and so on.
  • Yet another object of the present invention is to provide such a vibration damping device which has a long duration.
  • Yet another object of the present invention is to provide such a vibration damping device which can be quickly and easily installed.
  • an under-ballast damping device specifically designed for railroads, characterized in that said device comprises at least a flat element made of an elastomeric material or a plastics material, comprising a substantially flat top surface and a plurality of bottom ribs defining cross recesses therebetween adapted to at least partially engage therein respective damping section bars.
  • the vibration damping device which has been generally indicated by the reference number 1, comprises a flat or planar element 2, made of an elastomeric material or a plastics material, comprising a substantially flat top surface 3 and a plurality of bottom ribs 4 defining a corresponding plurality of cross recesses 5 therebetween, designed for at least partially engaging therein respective damping section bars 6.
  • a second flat or planar element 22 analogous to the first flat element 2, and comprises a substantially flat bottom surface 33 and a plurality of ribs 44 which also define a plurality of cross recesses 55 designed for engaging therein, at least partially, the mentioned damping section bars 6.
  • the damping devices are advantageously made as strips having a minimum width of 500 mm, a set length and a thickness of substantially 23 mm.
  • the flat elements are made of a compact rubber compound, or a plastics material compound, and their vibration damping properties are assured by their specifically designed tooth pattern.
  • the homogeneous or even thickness of the surface layer which, as the device is applied, will contact the ballast 7 of the railroad, and the hardness of said surface layer will provide the device with a long duration.
  • the damping device or "mattress” can be made in several patterns depending on the desired stiffness and damping to the obtained thereby.
  • the device must be applied under the ballast, i.e. between the extrados of the foundation sole 8 and said ballast 7, as is schematically shown in figure 6.
  • the device will be installed through the overall extension of the railroad line, and not only under the sleepers thereof.
  • the devices 1 comprises moreover locking or latching means, including a cross tooth element 9, formed on an end portion of the flat element and a cross recess 10 formed at the opposite end thereof.
  • the cross tooth element 9 of a flat element is designed for engaging in the cross recess 10 of an adjoining flat element, as is clearly shown in figure 4.
  • the subject vibration damping device can be used both under said ballast or under reinforced concrete slabs.
  • the vibration damping action is provided by the damping section bars 6, made of foamed rubber, and obtained by extruding or drawing operations, whereas the protection from the ballast, or concrete casting, depending on the application type, is provided by the top surface 3.
  • a main feature of the vibration damping device according to the invention is that the damping section bars 6 can be easily interexchanged depending on the railroad type such as railroad proper, tramway, and so on, without the need of modifying the flat elements 2 and 22.
  • the vibration damping device 101 comprises only the top flat element 2 and damping section bars 6, without the second flat element.
  • top flat element 2 can also be used individually, i.e. without the damping section bars 6 and the bottom flat element 22, as a damping device.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements and the status of the art.
