Definitions

  • the present invention relates to a rail protection device for railway tracks according to the preamble of claim 1 and a system of sound insulation device and rail.
  • a soundproofing device which is designed so that it can absorb high dynamic loads and thus in particular for noise protection on high-speed rail lines, for example, up to 200 km / h is suitable, extending about 3 m above the rail top.
  • Such soundproofing devices effectively attenuate the sound emitted when driving on the railroad, but are associated with relatively high costs and impede both the view of the travelers on the environment as well as the landscape or the overall urban appearance.
  • Object of the present invention is to propose a soundproofing device, which is structurally simple and is subjected to less wear during operation, while they should also be less sensitive to manufacturing tolerances.
  • the other disadvantages of previously common solutions should be eliminated.
  • the soundproofing device should have a high soundproofing performance at a low level have constructive effort and thereby affect neither the view nor shape the landscape significantly.
  • the inventors have recognized that by providing at least one sliding bearing between the soundproofing element and the foundation, for example in the form of a slot guide into which a guide element, in particular a mandrel, engages, in a particularly simple and cost-effective manner, length fluctuations, in particular those which are temperature-dependent, be compensated. Furthermore, this manufacturing and assembly-related tolerances can be compensated.
  • the slide bearing can be realized for example by means of sliding metal elements.
  • a friction-reducing element is preferably provided on at least one surface of the sliding bearing, for example in the form of a coating or in the form of an intermediate laying part, Teflon in particular being used.
  • Such a sliding bearing prevents the soundproofing element rests directly on the foundation and thereby abrasion in use.
  • This slide bearing is arranged for this purpose on the underside, ie the horizontally extending narrow side of the soundproofing element.
  • the sliding bearing thus extends horizontally in the longitudinal direction of the soundproofing element. It may be inclined relative to the vertical, and that perpendicular to the longitudinal extent of the soundproofing element.
  • the sliding bearing can be provided between this base element and the foundation and / or between the base element and a soundproofing element arranged thereon.
  • the sliding bearing can thus be arranged directly on the foundation or indirectly with the interposition of another element.
  • At least one first damping element in particular a first elastomer bearing, is provided between the soundproofing element and the foundation.
  • This first damping element causes a damping between the horizontally extending narrow side of the soundproofing element and the foundation.
  • noise emissions into the environment can be prevented by the sound insulation elements themselves, since vertically or with inclined sound insulation elements inclined running vibrations of the soundproofing element are damped against the foundation.
  • the longevity of the soundproofing device is significantly increased, because thereby the material of the foundation or soundproofing impairing work of the soundproofing elements against the foundation can no longer be done.
  • a base element is provided between the soundproofing element and the foundation on the foundation, advantageously such a first damping element can alternatively or additionally also be provided between the base element and the foundation.
  • the first damping element is preferably arranged directly on the sliding bearing.
  • the term "clearance gauge” implies that rail vehicles and their wagons or trailers when passing over the rail path have an extent that is arranged at least partially vertically above individual areas of the sound insulation elements. This will prevent sound from the soundproofing elements reflected on the outside of the rail vehicles and cars and can get from there directly or via further reflections in the environment.
  • the punctual foundation designed as a flat or deep foundation, in particular concrete base or steel support base are provided. These foundations are particularly easy to implement, where, for example, the steel support base can be rammed or shaken.
  • At least one elastic element is arranged, which compensates for irregularities in the distance between railroad track and soundproofing device.
  • the soundproofing elements are formed inclined with respect to the vertical in the direction of the rail. This ensures that the noise emitted by rolling noise and braking sound is significantly reduced by the soundproofing and sound reflected by the sound elements not reflected in the environment, but reflected in the track bed and recorded there, resulting in an overall significant imitation of a significant reduction in the environment Achieve sound.
  • the increased effectiveness of the soundproofing device according to the invention is thus achieved by a combination of the inclination with the underreaching of the clearance space.
  • the inclination relative to the vertical is 5 ° to 45 °, preferably 10 ° to 30 °, in particular 15 ° to 25 °.
  • the length of the soundproofing element is 1 m to 12 m, preferably 3 m to 9 m, in particular 5 m to 7 m.
  • At least one transitional aid is provided, which preferably has at least one step, wherein in particular it is provided that steps facing the rail path are removably arranged.
  • the soundproofing device can be overcome very easily during maintenance or evacuation measures both from the outside and from the inside.
  • the outer levels can be integrated directly into the foundation, for example, a concrete foundation may include cast-in stages.
  • a cover of the soundproofing element is designed as a transitional aid.
  • the crossing aid is provided in the area of the foundation because it can be arranged there particularly easily and inexpensively.
  • a carrier in particular in the form of an H-beam, is arranged between at least two soundproofing elements, in which soundproofing elements are inserted on both sides. Then the soundproofing elements can be kept and secured particularly effective.
  • the sliding bearing may alternatively or additionally also be arranged between this carrier and the soundproofing element.
  • At least a second damping element in particular a second elastomeric bearing may be provided between the vertical support and the soundproofing element so that on the one hand sound emissions into the environment can be prevented by the soundproofing elements themselves and on the other hand the longevity of the soundproofing device is substantially increased in this respect as well no materials impairing working of the soundproofing element relative to the vertical support can be done more.
  • the first damping element and the second damping element can also be realized as a uniform Dämpfungslement.
  • the soundproofing element is arranged so that it can be spaced away from the railroad track, because this makes maintenance considerably easier.
  • a hinge element can be provided on the foundation, whereby the soundproofing element can be spaced in a defined manner and moved back to the original position. This happens simply by turning part of the foundation or structure on the foundation down the slope so that maintenance vehicles can easily use the rail track.
  • Fig. 1 is purely schematically the sound insulation device 1 according to the invention in relation to a rail path 2 shown in section.
  • the rail 2 is a railroad track, for the standard, a clearance gauge 3 is set. Alternatively, it may also be a tram track, S-Bahn track or the like.
  • This clearance space 3 is used for fixing of areas that need to be clean, so that rail vehicles or wagons (not shown) can not collide with facilities and elements of the railway 2 or other installations, such as platforms and the like.
  • the soundproofing elements 4 of the soundproofing device 1 are arranged opposite to the clearance profile 3 in such a way that they engage at least partially under this. This means that when driving on the railway 2, the rail vehicle or a rail car at least partially overlaps the soundproofing elements 4, so that largely due to rolling and braking noise propagating sound can only get into the environment in a reduced form, since he of the sound insulation elements 4th taken up or reflected back into the ballast bed 5 of the rail 2 and recorded there.
  • the soundproofing device 1 thus attacks where the sound significantly develops, so that largely impairments of the view from the rail vehicle and the landscape image are avoided.
  • the soundproofing device 1 is structurally very simple and therefore cost-effective, as explained in more detail in particular in connection with the following description.
  • a first preferred embodiment of the soundproofing device 10 which has a punctual flat foundation using a reinforced concrete precast foundation with concrete bases 11.
  • H-beams 12 also known as double-T beams, are arranged on the concrete bases 11, which have an inclination of 20 ° in the direction of the rail path 2 with respect to the vertical V.
  • results are on both sides of each H-beam 12 soundproofing elements 13 inserted into the U-shaped receptacles 14 of the H-beam 12.
  • These soundproofing elements 13 are preferably six meters long (but can be made to adapt to the local situation but also in any other length) and have a centrally disposed acoustic insulation panel 15, for example made of rock wool, which is laterally bounded by edge plates 16 (profiled sheets) and wherein outside side covers 17 are provided. Furthermore, the soundproofing elements 13 each have a top flange 18 and a bottom flange 19. On the lower flange 19 bearing plates 20 are arranged, have the elongated holes 21. Mandrels 22 engage in these oblong holes 21 as guide elements which position the soundproofing elements 13 in relation to the H-beams 12 and at the same time permit thermal expansion. For damping both in the vertical and against lateral vibration elastomeric bearings 23, 23a are provided.
  • the sliding bearing formed by the bearing plate 20 and mandrel 22 extends apparently horizontally in the longitudinal direction of the soundproofing element 13.
  • the horizontally extending narrow side of the soundproofing element 13 thus extends parallel to the lower flange 19.
  • the sliding bearing is inclined relative to the vertical, in the present case based in the direction perpendicular to the longitudinal extension of the soundproofing element 13 inclined to the rail 2.
  • the soundproofing element (not shown) is constructed not in several parts but in one piece or without a lower flange, then such slot guide is arranged on the lower horizontal narrow side of the soundproofing element.
  • a bearing plate 20 and mandrel 22 constructed slot guide and other plain bearings can be used. However, these should provide a largely low-friction sliding of the soundproofing element 13 relative to the foundation 11 and also cause lateral guidance of the soundproofing element 13 with respect to the H-beams 12 acting as vertical beams.
  • the concrete base 11 has incorporated treads 24 and a tread 25 remote from the tread 25 is further arranged on the H-beam 12 a tread 26 away from the rail path 2 and another tread 27 on the part of the rail 2. This tread 27 is removable Designed to facilitate the work during maintenance. Finally, the H-beam 12 is covered above a cover plate 28, which also serves as a footboard. In this way, the soundproofing device 10 can easily be overcome in the area of each foundation 11 for maintenance or evacuation measures both from the outside and from the inside.
  • a ground connector 29 is provided to provide a continuous rail ground.
  • an elastic skirt 30 is disposed on the lower flange 19, which rests elastically on the slope 31 of the rail 2 and so by means of their sufficiently dimensioned height differences between embankment 31 and lower chord 19 compensates. The elastic skirt 30 so unwanted spaces are avoided for sound leakage.
  • 30 passages for small animals can be integrated into the elastic apron.
  • 13 such passages can be integrated into the soundproofing elements, if necessary.
  • the inner step 27 can be removed. If more extensive maintenance work, for example, in reconstruction work on the superstructure, and in particular to perform maintenance on the embankment 31, the shallow-founded concrete base 11 can be lifted easily.
  • the soundproofing device 10 has a very simple construction and can also be easily set up and removed. In addition, the soundproofing device 10 is very effective against sound emitted in the wheel-rail area and prevents its leakage into the environment very effectively.
  • a second preferred embodiment of the soundproofing device 40 according to the invention is shown purely schematically. It can be seen that, in contrast to the first preferred embodiment 10 according to the Fig. 2 and 3 in this case there is no shallow foundation with a concrete base 11, but a deep foundations using a vibrated or rammed steel beam 41 is present.
  • the H-beam 42 is disposed above a removably arranged horizontal cross member 43.
  • the construction is the same as in the first preferred embodiment 10 according to FIG Fig. 2 and 3 , which is why the separate description of the same elements is omitted.
  • the cross member 43 is bolted to the steel beam 41 and can be removed during maintenance.
  • treads 44 are arranged on the outside and a removable tread 45 on the inside.
  • a cover plate 46 in turn forms an upper step.
  • This preferred embodiment is used above all when there is no sufficient slope width, so that no concrete base 11 requiring a relatively large contact surface can be used.
  • such deep foundations will always be used when the soil conditions do not allow for flat foundations.
  • the horizontal cross member 43 can be overwhelmed for the production of a peripheral path behind the soundproofing device.
  • the clearance 3 at least partially cross-sound insulation elements 13, which are arranged inclined relative to the vertical, it is of course also possible, according to the invention used, horizontally extending sliding bearing also arranged next to the clearance profile and in particular for high sound insulation elements to use.
  • the soundproofing device 10, 40 according to the invention is structurally very simple and is subjected to a much lower wear during operation, as conventional soundproofing devices, and manufacturing and assembly-related tolerances are compensated.
  • the soundproofing device 10, 40 according to the invention also has a high sound insulation performance with low design effort and thereby neither affects the view nor significantly shapes the landscape.
