Definitions

  • the technical solution relates to a railway or tramway track with modular panels of a low noise barrier reducing noise and vibration and arranged outside the track, wherein the modular panels reducing noise and vibration contain at least one non-humic layer, which absorbs water, reduces the rate of its flow and outflow and allows its evaporation, as defined in the preamble of claim 1.
  • noise barriers are most commonly used. These noise barriers are made of boards or panels placed along the railway or tramway track. Another option is using horizontal structural pads from noise and vibration absorbing materials, which fill the track space, or it is possible to use a combination of both types of measures.
  • modular panels with interlocking edges and vertical chambers, which are made from a porous sound-absorbing material, based, e.g., on wooden fillers, wood shavings, and are cement-bonded, whereby these modular panels are on the outer sides of the railway track supplemented with low concrete prefabricated noise barriers.
  • the rail track composed of a rail grid with gravel ballast or a solid railway, contains systems of inner and outer panels with at least one sound absorbing layer, a system of clamp stabilizers and a directional barrier.
  • the aim of the technical solution is to eliminate or at least minimize the disadvantages of the background art, especially to allow the building of railway tracks with a continuous arrangement of the railway substructure and superstructure for maintaining the same stiffness of the track construction in the longest possible section, while reducing effectively noise and vibration levels and allowing to build the so-called green tracks with lowered costs of maintaining green areas, i.e. with improved water retention and evaporation in the track area.
  • the advantage of the proposed solution is the fact that it can be used both on the tracks with a conventional railway superstructure composed of rails, transverse sleepers and gravel ballast, and on railways with a solid carriageway composed of rails and a concrete slab without gravel ballast.
  • the solution can be in its embodiment preferably used also on railway tracks built on bridge constructions, where it can at the same time create escape routes for passengers and operating staff in case of accidents or emergencies.
  • the actual modular panels are formed by a wire supporting spatial structure from surface protected iron, into which are inserted individual sound absorbing and optionally acoustically reflective layers and a retention pad, which consists of recycled synthetic materials or a stone agglomerate or wad, whereby these layers are sandwich arranged in the wire spatial structure and extend in the vertical direction.
  • the sandwich layered panel thus created is on the side adjacent to the railway track always provided with a sound absorbing layer, which is in a preferred embodiment accompanied by a fair-faced wall with spatial recesses to ensure sufficient noise attenuation.
  • the panel On the side away from the rail track the panel is composed of sloping structuring of the individual layers forming a cascade for planting live vegetation and/or forming a sloping surface for installing an artificial grass carpet.
  • the individual modular panels may be mutually mechanically connected by wire spirals and/or clamps.
  • the modular panels of the low noise barrier with the function of water retention are designed on the side facing the track in such a manner that the shielding wall is rounded by at least one parabolic surface, wherein the focus of the parabola preferably lies outside the track on the edge of the gravel ballast or the gravel addition of the solid railway.
  • the shielding wall enhances the efficiency of the panel in noise and vibration attenuation.
  • the modular panels are for increasing the overall structural stiffness provided with a rigid air soundproof plate and/or a stone layer in their inner part.
  • the modular panels are in their lower part formed by a rigid plate from recycled rubber, concrete or cement composites.
  • the modular panels are supplemented with at least one set of pores from air permeable materials or stone dams.
  • the modular panels with the function of water retention comprise a core consisting of retention layers, which are supplemented and/or interspersed with fine aggregate with an admixture of humus soils and the actual surface casing of the panel is formed by a stone dam with xerophilous plants or bushes, whereby the thus formed panel creates organic space for living invertebrates and insects, such as xerophilous species of butterflies, beetles, hymenoptera, Diptera, or hydrophilic species of bugs, dragonflies, etc., including small mammals or reptiles.
  • This embodiment of the utility model creates new living space within the existing environmental structuring of the townscape and, at the same time, compensates for the areas occupied by the construction or modernization of the rail track.
  • the modular panels have a sloping or cascade design so that they could be placed at the end of the sets of low noise barriers.
  • the upper surface of the modular panels is covered with a humic layer with vegetation cover, most often with various types of grass or sedum.
  • the upper surface of the modular panels is covered with an artificial grass carpet, mechanically attached to the surface of the individual absorbant layers and/or bonded or mechanically attached to the supporting portion of the wire structure of the modular panel.
  • the non-humic layer is composed of water absorbing and water permeable synthetic clumps. According to another embodiment, the non-humic layer is composed of a water permeable porous agglomerate from non-absorbent inert materials.
  • the modular panels have a spatial recess in their bottom to hold water and/or allow water drainage from the panel.
  • the modular panels contain transverse vertical stiffeners.
  • the non-humic layer is planted with plants.
  • Figs. 1 to 7 whereby the principle consists in the fact that at least one non-humic layer is inserted into a modular panel of a low noise barrier, whereby this layer absorbs water, reduces the rate of its flow and outflow and, at the same time, allows its evaporation.
  • the non-humic layer we understand a layer which does not contain soil or, more specifically, soil for growing plants.
  • Fig. 1 shows a railway or tramway track comprising rails 1 , which are mounted in fastening systems 2 on transverse sleepers 24 forming a rail grid mounted in gravel ballast 25 , which is mounted on the unmarked structure of the substructure of the track comprising a drainage system of the earth subgrade.
  • the distance between the axes of the transverse sleepers 24 is determined by a respective regulation, most often being in the range from 600 to 800 mm.
  • the individual modular panels 3 with the function of water retention contain a specific number of, but at least one, retention and damping pad 15 , whereby the individual modular panels 3 are demoted in sets outside the track and are mutually connected by means of connecting spirals or clamps 7.
  • the set of modular panels of the low noise barrier with the function of water retention is mounted on a compacted gravel cushion 8 , which may be on both sides lined with concrete curbs 9 or by unillustrated concrete prefabricated parts in the form of the letter L or T.
  • a compacted gravel cushion 8 On the side away from the rail track the modular panel is provided on its sloping surface 12 with a humic layer 10 , which fills gaps in cascades 11 of the retention and damping pads 15.
  • the sloping surface 12 is preferably planted with suitable ground cover plants or bushes 13. In an unillustrated embodiment, the sloping surface 12 may be created without a humic layer 10 and a carpet of artificial grass 14 is installed on it surface.
  • the retention and damping pads 15 are composed of a recycled wadding synthetic material, e.g., the recyclate available under the trade name STERED, which is manufactured according to SK UV 6673, where the density of the individual parts of the sandwich layering of the retention and damping pads 15 determines not only specific retention and damping capabilities of a particular embodiment of the modular panels 3 , but also, in a combination with other layers and/or pads, their mechanical and damping properties, namely also from the viewpoint of damping an impact of a road vehicle.
  • STERED the recyclate available under the trade name STERED
  • the retention and damping pads 15 consist of special types of sound absorbing porous concrete made from natural crushed stone or consist of similar agglomerates based on recycled concrete or bricks.
  • the modular panels 3 are provided with a spatial stiffener 16.
  • Fig. 2 shows a railway or tramway track from Fig. 1 , modified by the fact that inside the track, i.e. between the rails, are in the direction of the track length mounted inner panels 17 of rail absorbers and outside the track, i.e. along the outer edges of the rails 1, are in the direction of the track length mounted outer panels 18 of the rail absorbers.
  • the length of the panels 17 and 18 is a multiple of the axial distance of the fastening systems 2 and is not dependent on the length of the modular panels 3.
  • the surface of the rail noise absorbers with the function of water retention is formed by an unillustrated natural cover or artificial grass.
  • the railway or tramway track from Fig. 1 is modified by the fact that both inside and outside the track structural and vegetation humic layers are laid on the gravel ballast 26 to be covered with natural lawn.
  • Fig. 3 shows a modular panel 3 with the function of water retention, where the supporting structure is formed by a wire basket 19 with retention and damping pads 15 which are inserted in it individually, most often vertically, and a sound-absorbing layer 4 with a fair-faced wall 5 containing spatial recesses 6.
  • the bearing surface is composed of a spread footing 20 , which most typically consists of recycled rubber or a shell concrete plate.
  • the sloping surface 12 comprises pockets 21 arranged in a cascade, which are filled with a humic layer 10 , which is preferably planted with ground cover or xerophilous plants or bushes 13.
  • the sloping surface 12 is made without a humic layer 10 , whereby the individual vertical layers constitute the bearing surface for the installation of a carpet from artificial grass 14 , which is mechanically connected to the structure of the wire basket 19 and/or bonded to it.
  • Fig. 4 represents a modular panel according to Fig. 3 , modified by the fact that behind the sound absorbing layer 4 with an unillustrated fair-faced wall 5 containing spatial recesses 6 is inserted at least one rigid and soundproof plate forming a shielding wall 23 to increase the soundproofing qualities of the panel.
  • Fig. 5 shows a modular panel according to Fig. 3 , modified by the fact that it contains a system of air channels 22 for increasing water evaporation from the retention and damping pads 15 , whereby preferably these channels can be formed by an unillustrated stone dam.
  • Fig. 6 represents a modular panel according to Fig. 3 , modified by the fact that on the side facing the rail track a shielding wall 22 is formed, resembling a parabola in form, whereby its unillustrated focus lies outside the track and its surface can be provided with a sound absorbing layer 4 with an unillustrated fair-faced wall 5 containing spatial recesses 6.
  • Fig. 7 shows a modular panel according to Fig. 3 , modified by the fact that on the side away from the rail track there is a sloping surface 12 , which is formed by complete or partial fair-faced surface made from a stone dam 24 , whereby the inner core of the modular panel 3 contains unillustrated retention and damping pads 15.
  • the technical solution can be preferably used for building railway and tramway tracks in town residential areas, in areas of nature reserves and on bridge constructions. Combining this solution with known rail noise absorbers or with natural grassing further increases the overall efficiency of the attenuation of noise and vibration from wheel/track contact and significantly improves water retention in the track without compromising rail operation.
