Definitions

  • the present invention relates to a modular permanent way including tracks and track equipment (switches and crossings) for tramways and subways and a process for laying the same.
  • the rails are fastened to wooden or reinforced concrete sleepers, embedded in a ballast, which in turn lies on a leveling bed of various kinds, such as natural or backfill soil.
  • the ballast has the purpose of distributing loads and maintaining track geometry.
  • the ballast does not ensure track stability with time, as it tends to be subjected to gradual sagging which lead to intolerable changes in the overall track geometry.
  • Removal of the paving, dismantling of the old system, excavation and trench leveling, placing of the ballast, laying of sleepers and rails and final repaving involve an estimated works duration - depending on node complexity - of at least two weeks.
  • the ballast is being replaced by more stable substructures, essentially consisting of reinforced concrete slabs, laid on a poor concrete leveling bed, with an elastomeric mat being generally interposed between the bottom bed and the slab, for vibration damping purposes.
  • the track or track equipment (switch or crossing) is built on such slabs, with the so-called “Milano” system, in which the rails are secured using metal plates, the latter being fastened to the slab with bolts and maintained at the design level using on site-built blocks of quartz sand and epoxy resin.
  • ballasted turnout e.g. consisting of two switches and one crossing
  • Each modular member bears a rail section, which is removably secured to the modular member itself.
  • the modular members are laid in parallel pairs on a metal support structure, which is placed in a trench.
  • the support structure lies on the bottom bed by supporting screws, which allow level adjustment of the structure and the modular members supported thereby.
  • Tie rods are further provided to adjust the distance between the modular members, i.e. the gauge (predetermined distance between the inner edges of the track rails).
  • the portion underlying the support structure is filled with injected concrete.
  • the design and actual construction platform has its extrados at the same height as the rail surface (rolling surface) and the road surface - as the rail is embedded therein - wherefore it does not allow to use pavements like those currently in use (bituminous pavements or granite block pavements) or new pavements complying with urban environment choices.
  • Each modular elements has bumps on one side, which act as rail supporting surfaces
  • the rails are anchored to such bumps by means of stirrups and bolts.
  • This technology also has a number of drawbacks.
  • the object of this invention is to obviate at least some of prior art drawbacks and particularly the drawbacks set out hereinbefore.
  • numeral 1 generally designates a prefabricated modular member for making a permanent way, including tracks and track equipment.
  • the modular member 1 includes a reinforced concrete platform 2 having two main surfaces 2a, 2b and one lateral peripheral surface 2c.
  • the two main surfaces 2a, 2b are preferably, but without limitation, parallel.
  • the thickness of this platform is preferably of 200 to 300 mm.
  • At least one pair of rails or special track equipment parts 7 are secured to one of the main surfaces 2b of the platform.
  • the rails may be either standard track rails or special rails for switches.
  • the modular member 1 has at least one vent-hole 3 - whose function will be better explained hereafter - whose ends open out of both main surfaces 2a, 2b.
  • Each vent-hole 3 has preferably a diameter of 40 to 60 mm.
  • first anchors 4a are provided at one of said main surfaces 2a, 2b.
  • a plurality of second anchors 4b is further provided at the lateral peripheral surface 2c, for the platform 2 to be also upturned.
  • these first and second anchors 4a, 4b are metal pins secured to the platform, having a substantially frustoconical head projecting into surface hollows 24a, 24b.
  • Metal pins of this type are sold, for example, by HALFEN-DEHA S.r.l. based at Urgnano (BG), Italy.
  • the modular member 1 also includes a plurality of level adjustment elements 5, 6, to adjust the height and inclination of the platform 2 as it is laid, as explained in greater detail below.
  • the level adjustment members are operable either from above or from the side that supports the rails 7 or the track equipment 7.
  • each of said level adjustment elements comprises an internally threaded bushing 5, which is inserted in the platform 2, transverse to the main surfaces 2a, 2b, and is designed to receive a screw 6.
  • the rails and/or the special track equipment parts 7 lie on rubber pads 17 and the rails 7. are connected to the prefabricated modular member 1 by means of an elastic attachment, better known as plate 10.
  • the rails and/or the special track equipment parts 7 are anchored to said platform 2 by means of screws 30, whose heads are inserted in guides 11, which are embedded in the platform 2 and placed transverse to the rails 7.
  • the guides 11 are usually essentially orthogonal to the rails 7.
  • the guides 11 are transverse but generally non orthogonal to the rails 7.
  • the transverse - but not necessarily orthogonal - position of rails may be adjusted with the utmost accuracy, while preventing any misalignment between the tracks of adjacent modular members.
  • an additional plate 27 (usually made of iron), is placed between the platform and the rubber pads 17, and is anchored to the platform 2 by means of screws 30, whose heads are inserted in guides 11, which are embedded in the platform 2 and placed transverse to the rails 7.
  • This arrangement generates an additional thickness for accommodating the stone block pavement.
  • the screws 30 are Halfen HS 50/30 screws and the guides are Halfen HTA 50/30 screws, sold by HALFEN GmbH & Co.KG, Germany.
  • the prefabricated modular member may include a housing 14 to receive a switch machine, whenever the platform is designed to be placed in the switch point area.
  • one of the main surfaces 2a - particularly the one opposite the surface whereto the tracks are secured - and the lateral peripheral surface 2c are covered by an elastomeric vibration damping mat 9.
  • This mat is preferably 10 to 30 mm thick.
  • the prefabricated modular member described herein is used to make a permanent way, including tracks and track equipment.
  • the process for making the permanent way including tracks and track equipment 7 using the above prefabricated modular members includes a first excavation step to form a trench 12 and later compaction of the bottom 13 of the trench 12.
  • a poor concrete cast having a thickness of 10 to 20 cm is possibly applied to the bottom 13 of the trench 12.
  • One or more steel plates 20 are further placed on the bottom of the trench.
  • At least one prefabricated modular member 1 is placed in the trench 12.
  • each prefabricated modular member 1 is adjusted.
  • This special self-leveling mortar may be the "MICROBETON BS91 ANCORA", sold by TECNOCHEM ITALIANA S.r.l., based at Barzana (BG), Italy.
  • vent-holes 3 allow all the air trapped under the platform 2 to be exhausted, to obtain full mortar filling.
  • the transverse position of the rails 7 of each modular member 1 may be also adjusted, to prevent any misalignment between adjacent track sections.
