Definitions

  • the object of this invention is a rail superstructure assembly with vibration damping, particularly for railway lines in tunnels, comprising rail support blocks located transversally in appropriate housing seats arranged longitudinally in relation to the rails, with interposition of flexible damping components.
  • ballast which provides a flexible supporting base, capable of damping vibrations to a large extent; however, while such ballast proves satisfactory for non-urban lines, or those located remote from buildings, it is not sufficient for many systems, for example in the case of underground railway lines, such as metropolitan lines, running underneath monuments, ancient buildings or special-purpose buildings, the structure or use of which could be jeopardized by the vibratory movement.
  • round ballast is subjected to the phenomenon of compaction during use and therefore requires regular maintenance operations, which are particularly demanding and difficult in the case of lines in tunnels with heavy traffic.
  • each prefabricated member is independently built into the concrete casting forming part of the track supporting bed; the facing prefabricated members of two parallel rails forming a track may be interconnected by a linking crossmember, preferably consisting of a metal section, capable of ensuring constant spacing and if necessary of being removed after positioning of the prefabricated members and hardening of the casting.
  • the structure should furthermore be comprised of the smallest possible number of components to facilitate and make highly repeatable the production and assembly thereof prior to being placed in position on the ground.
  • the present invention provides a rail superstructure assembly with vibration damping particularly for railway lines in tunnels, consisting of a prefabricated member comprising a block carrying the rail fasteners, made of concrete and enclosed in an envelope, open at the top, of rubber or the like, having vibration damping properties, the entire assembly being capable of being inserted via a bed casting into a concrete housing forming part of the track bed of the railway line, or at least of one of its lengths, there being provided damping components made of elastomeric material inserted lengthwise between the lower surface of such block and the envelope and between the housing and the rail supporting slab, respectively, there being furthermore provided means for centring the position of the housing with respect to the development of the track.
  • such envelope shall have inner surfaces with projections capable of facilitating adherence to the concrete block and that such housing shall comprise at least one pair of seats located crosswise and a multiplicity of seats located lengthwise in order to accommodate the rail supporting blocks.
  • such means for centring the housing with respect to the track bed consist of a through-hole drilled in the housing and of a pin or the like made integral with the slab in a preset position and capable of being secured at the time of placing on site of the housing by the setting of hardening material.
  • the rail bed according to the invention is comprised of a concrete block 1 to which is attached a rail fastening unit 2 holding rail 3, which block is inserted in an envelope 5 made of rubber or the like.
  • Envelope 5 is provided, on its inner surface, with projections 5a, for example of annular form, capable of ensuring its adherence to concrete block 1; additionally, between lower surface 1b of concrete block 1 and lower surface 5b of envelope 5 there is interposed a further slab 4 made of flexible material such as rubber or the like in order to increase vibration damping.
  • the assembly consisting of envelope 5 containing antivibratory material 4 and block 1, equipped with rail fastening unit 2, forms a factory-made prefabricated member 12 which is therefore capable of being rapidly placed on site at the time of construction of the track line, constituting the component for supporting and securing the rails to the ground.
  • FIGS 2 and 3 show that each prefabricated member 12 is inserted in transverse seats 14a of an outer housing 14 made of pre-cast reinforced concrete, block 12 being secured thereto by means of bed casting 6; outer housing 14 rests in turn on a layer 16 of elastomeric damping material, such as microcellular rubber or the like, placed at the bottom of a hollowed-out duct 17 provided in slab 18, comprising the entire seat of the track.
  • a layer 16 of elastomeric damping material such as microcellular rubber or the like
  • Such housing 14 is furthermore provided in proximity to its middle zone, in a direction transversal to rail 3, with a through-hole 14c having a jagged inner surface 14d and capable of being inserted in a reference component 15 previously made integral with slab 18 in preset positions; once housing 14 is placed in the correct position, established by the matching of hole 14c with centring component 15, the remaining space is filled with hardening material which does not, however, become integral with pin 15, thus imparting to housing 14 the movement necessary to exert damping action on flexible components 16.
  • a certain number of prefabricated members 12 are inserted in a longitudinal direction parallel to rail 3 in corresponding seats 14b within such housing 14, which comes to constitute an appropriate mass suspended from flexible layers 16.
  • rail fastening unit 2 illustrated in figure 1 is comprised of a metal plate 7 anchored via tie rods 8 embedded in block 1 and provided with springs 9 capable of maintaining a constant tightening pressure with the interposition of a layer of elastomeric damping material 10; to the latter, via flexible tie rods 11, is fixed rail 3.
  • upper surface 1a of block 1 is inclined with respect to lower surface 1b, which is horizontal.
  • the vibration generated by the train is in fact comprised essentially of oscillatory movements in a vertical sense. Such movements are damped both by the compressive strain on slab 4 and by shear strain caused by the firm attachment of block 1 to envelope 5 and of the sidewalls of the latter to casting 6, and therefore to housing 14.
  • the components according to the invention also provide in each case particular advantages in terms of rapidity and economy of installation, since the moulding of block 1 with the relevant anchor points for the rails, and its enclosure within envelope 5, often involving delicate operations, is done in the factory, in a controlled environment and using the most suitable tooling, which conditions cannot be achieved on site, thus favouring industrial repeatability of the production of the beds according to the invention.
