Definitions

  • the normal method of constructing a heavy duty rail track is to provide a rigid base or foundation in the form of a concrete mass, or piles, with the metallic rail track mounted above the concrete mass, and the intervening gap filled with a cement or concrete grout or similar rigid filling material which can be introduced in a plastic condition and then allowed to harden. This allows the track rail to be accurately aligned and levelled.
  • the invention consists in a rail track assembly comprising a rigid concrete or other base, and a track rail located on a sole plate above the base, the sole plate being wider than the track rail and extending on both sides thereof, and in which the gap between the sole plate and base is occupied partly by a mortar or other rigid filling composition containing a hard setting synthetic plastics material, which extends laterally a limited distance, not exceeding or not greatly exceeding the lateral width of the sole plate.
  • the said gap on either side of the synthetic plastics composition, is filled with a cementitious or like relatively inexpensive mortar, grout, or other filling composition.
  • the central strip of plastics filling com position extends laterally over a total width not greatly exceeding the width of the botton flange of the track rail.
  • the lateral width of the synthetic plastics filling composition is preferably limited substantially to the width of an imaginary inverted pressure ridge, whose flanks pass close to the lower corners of the main vertical web of the track rail.
  • the assembly includes a second sole plate, of lesser width than the first sole plate, and positioned vertically between the first sole plate and the filling composition.
  • the assembly may also include means for levelling or adjusting the first or second sole plate, and means for anchoring the first sole plate in position thereon, after adjustment.
  • This provides a particularly convenient arrangement for repairing or replacing a rail track assembly where the original cementitious grout has failed, and enables great accuracy in levelling to be obtained.
  • FIG. 1 is a somewhat diagrammatic sectional end view showing the main component parts of a rail track assembly on a concrete base (with the main sole plate omitted for convenience) and illustrating the imaginary direct pressure ridge" below the rail,
  • FIG. 2 is another sectional end elevation illustrating a later stage in the construction with the metallic rail track and upper sole plate in position
  • FIG. 3 is another sectional end elevation illustrating the final stage in the construction.
  • FIG. 4 is a similar sectional end elevation illustrating another embodiment of the invention.
  • the invention is applied to a process of restoring or repairing a heavy duty rail track when the original cement grout filling below the sole plate of the track has failed in use.
  • the first stage in the process is to remove the existing rail from the normal anchorage bolts (see 28 in FIG. 2), hack out the original cement grout, and then scrabble a shallow groove or trough 10 in the upper surface of the concrete foundation or mass 11 immediately below the line of the track.
  • the depth of this trough may be about one quarter inch to one half inch and its width is preferably equal to or slightly greater than the width of the direct pressure ridge from the rail track. This pressure ridge is illustrated in FIG.
  • each side of the triangle is in this example 45, though in some applications the included angle at the apex may be as low as
  • the apex angle of the pressure ridge can be calculated theoretically and the width of the base of the triangle, which determines the width of the trough 10, can therefore be calculated from a knowledge of what will be the final vertical position of the rail itself, including all the intervening components and filling materials.
  • the next stage in the process is to position accurately a lower sole plate 20 over the shallow trough in the concrete, by means of a series of vertical levelling screws as indicated at 21.
  • the lower sole plate 20 in this example is a 6 inches X V2 inch mild steel fiat plate, to the underside of which are attached transverse mild steel strips 23, at three foot intervals, these transverse strips being designed to receive and locate the levelling screws.
  • an epoxy mortar in a plastic state is then introduced into the gap between the sole plate 20 and the concrete base, the epoxy mortar strip 24 being limited to the width of the trough 10 formed in the concrete, i.e. having a width which is approximately equal to or slightly greater than the width of the base of the pressure triangle, or the width of the base flange 26 of the rail itself.
  • the epoxy mortar includes a chemical hardening or curing agent and therefore hardens in situ.
  • the next stage in the process is to fix the anchorage bolts 28 as illustrated in FIG. 2, for which purpose the concrete mass 11 is drilled out and rag bolts are grouted into position, preferably with the same epoxy mortar.
  • An upper sole plate 30 is then positioned over the lower sole plate 20, and apertured lugs 31 welded at intervals along the opposite edges of the upper sole plate are then positioned on the bolts 28 and tightened down.
  • each anchorage comprising a stud 36 welded to the top sole plate 30 to locate an anchorage body 38 which holds a spring clip 39 bearing down on the adjacent part of the bottom flange 26 of the track rail.
  • the anchorages 34 comprise locators connecting the track rail to the sole plate.
  • the invention uses two separate sole plates 20, 30, which are not rigidly secured together before or'during assembly. This is particularly convenient when repairing an existing rail track assembly, since the lower sole plate can be accurately aligned and levelled before the upper sole plate and track rail are placed in position, and the epoxy mortar can be introduced below the bottom sole plate before the upper sole plate is positioned.
  • the second embodiment illustrated in FIG. 4 is intended for situations where great accuracy in levelling and alignment of the track rail is required.
  • parts corresponding to those of the first example are indicated by the same reference numerals.
  • sole plate 30 In this example only one sole plate 30 is used, both for anchoring the track rail and for levelling the assembly relative to the concrete base 11.
  • a series of levelling bolts 45 are grouted into holes drilled in the concrete base at closely spaced intervals positioned alternately on opposite sides of the track rail 15. These bolts carry nuts which cooperate with lugs 46 welded to the sole plate 30, and opposite each lug 46 on the other side of the track rail is provided a rail anchorage device 34 similar to that described in the previous example.
  • this track rail assembly In the construction and installation of this track rail assembly a groove is first scabbled in the concrete base, foam rubber pads 47 are positioned beneath both opposite edges of the sole plate 30, and with the track rail securely anchored to the sole plate by means of the adjustable anchorage devices 34, the whole assembly is accurately aligned and levelled by adjustment of the nuts on the levelling bolts 45. In doing so the sole plate 30 is pulled down onto the rubber pads 47. Epoxy grout is then introduced into the space between the sole plate 30 and the trough 10, for which purpose the sole plate is formed with a series of grout filling holes 48 along one side, and a series of air escape holes 49 along the other side.
  • This epoxy grout filling operation may be performed in short lengths of say 1 or 2 metres with transverse dividers or partitions inserted at intervals along the length of the rail.
  • the width of the epoxy grout 50 is effectively limited to the transverse width at this height of the pressure ridge 12 whose flanks pass through the lower corners of the vertical web of the track rail.
  • a heavy duty rail track assembly comprising a rigid concrete base, a metal sole plate mounted above said base, a track rail located on said sole plate, locators connecting said track rail to said sole plate, anchorages connecting the sole plate to said base, a layer or a rigid filling composition containing a hard setting synthetic plastics material between said sole plate and said base, the width of said filling composition being limited to less than the lateral width of the sole plate, and means confining the said filling composition to said limiting width.
  • A-heavy duty rail track assembly comprising a rigid concrete base, .a metal sole plate mounted above said base, a track rail located on said sole plate, locators connecting said track rail to said sole plate, anchorages connecting the sole plate to said base, a layer of a rigid filling composition containing a hard setting synthetic plastics material between said sole plate and said base, the width of the said filling composition being limited to less than the maximum transverse distance between the outer edges of said locators, and means confining the said filling composition to said limiting width.
  • a heavy duty rail track assembly comprising a rigid concrete base, a metal sole plate mounted above said base, a track rail located on said sole plate, locators connecting said track rail to said sole plate, anchorages connecting the sole plate to said base, a layer of a rigid filling composition containing a hard setting synthetic plastics material between said sole plate and said base, the width of said filling composition being limited to less than the maximum transverse distance between said anchorages, and means confining the said filling composition to said limiting width.
