Definitions

  • the constituents of a synthetic elastomer, including the swelling agent are mixed, and the mixture obtained is injected into a mold, or conformator with vents, surrounding the crosspiece, and providing with the latter a volume for receiving and expanding the mixture during polymerization. After hardening, the former is removed to obtain an elastomer sole that adheres directly to the surface of the crosspiece.
  • the present invention is concerned with railways with ballast, and with the action of visco-elastic soles as identified above, with respect to the attrition of the concrete parts of the various track supports, in contact with the ballast.
  • visco-elastic material any material, natural or synthetic, having mechanically the properties of a rubber, that is to say both flexible, significantly deformable, and elastic.
  • ballast wear and packing seems essential for the operation of current railways, on which convoys that are becoming heavier, or faster and faster, such as high-speed trains.
  • the ballast wear is increased compared to that of other types of support, due to the greater inertia of concrete parts or elements, and in particular on platforms. hard, or engineering structures with a concrete deck. This wear normally leads to a degradation of the geometry of the track, more and more rapid between each leveling-dressing operation, and eventually requires the renewal of the ballast, if only to restore it to suitable rheological and drainage properties. .
  • the frequency of these operations is reduced, or at equal frequency of these operations, the thickness or volume of the ballast can be reduced.
  • the solution according to the invention provides an additional stage of elasticity to the railway, in addition to that already existing between the rail and the cross-member. This contributes to reducing the overall stiffness of the rail / sleeper / ballast system. This also makes it possible to dissipate in the aforementioned system the vibratory energy generated by the rolling loads, in particular when the latter cannot be absorbed by the platform, for example if the latter is a concrete deck of a structure. .
  • the present invention also provides another advantage relating to the use of the visco-elastic material, for example a synthetic elastomer.
  • a synthetic elastomer for example a synthetic elastomer.
  • the visco-elastic material in the liquid state. or pasty, during polymerization, directly on concrete parts.
  • the elastomer can be deposited in a layer, according to at least one of the following techniques, namely projection, casting, application by brush or roller, on the underside at least of the concrete parts.
  • This procedure generally consists in rotating in a steel drum, steel balls, calibrated elements of ballast and, concrete cubes uniformly coated, without joints, with a layer of visco-elastic material , in particular elastomer, to be tested, and to observe the loss in weight of these cubes, as a function of the number of revolutions of the drum.
  • the load is then introduced into a steel drum of a testing machine, with a rotational speed of 33.33 revolutions / minute. At regular intervals, for example every 500 revolutions, the machine is stopped, the ballast and the concrete blocks are weighed, and their weight loss is noted, in percentage relative to P'and P respectively.
  • the visco-elastic materials suitable according to the invention must lead to a loss of weight of the concrete cubes, according to the procedure explained above, of less than 0.2%, after 1500 revolutions of the drum of the testing machine.
  • polyurethane It is for example a two-component polyurethane, as sold by the Company BAYER under the names BAYTEC 308/309 and BAYTEC 310/309.
  • This polyurethane is obtained directly, that is to say without solvent, by direct polymerization of a polyetherpolyol and DMI (disocyanate - diphenylmethane).
  • This polyurethane can be used with any suitable material for hot spraying, with drying of the spraying air, for example a material of the UNIPRE brand.
  • a crosspiece according to the invention or rail support, comprises two pieces 1 of reinforced concrete, or blocks, spaced from one another, and connected by a metal spacer 2.
  • On the upper side 1a of two blocks are fixed respectively two rails 3, in suitable recesses recessed slightly inclined towards one another, and with fixing means not shown.
  • An elastic sole, not shown, is interposed between the rail and each block.
  • the lower face 1b of a single-piece concrete cross member 1 is coated with a sole 4 made of elastomeric material, adhering to the substrate of the cross member in two separate adhesion zones, corresponding to two buffers 4a and 4b, arranged opposite the two rails 3 respectively.
  • FIG. 5 it is a concrete support 1 for a switchway.
  • the lower face 1b of support is partially covered by a sole 4 of visco-elastic material, consisting of different buffers 4a, 4b and 4c, arranged vertically above the rails 3 of the track apparatus respectively.
  • FIG. 6 it is a simple concrete block 1, coated on its underside 1b with a sole 4 made of elastomeric material, adhering on one side to the concrete substrate, and in contact with the other. side with ballast 5.
  • Supports or crosspieces in accordance with the present invention as shown in FIG. 1, and coated with the BAYTEC material with a thickness of 0.5 cm, were tested according to the procedure known as "unidirectional vibrator", explained with reference to the figure. 7.
  • ballast load 51 In a concrete pit 50, there is a ballast load 51, having a minimum DRG hardness coefficient of 17 according to standard NF F 53695.
  • a cross member 52 with its blocks 53 is arranged horizontally in the pit on the ballast.
  • Two rails 54 of limited length are each mounted on a block, parallel to each other, and perpendicular to the crosspiece.
  • Two loads 55 are applied to the two ends respectively of the same rail, five meters on either side of the cross-member, to give each rail an arrow of approximately 10 cm, and to represent a preload of 40 kN on the crosses.
  • a unidirectional vibrator then transmits to the cross member to be tested, via a beam and two rails 54, a sinusoidal vertical force of ⁇ 45 kN, at the frequency of 50 Hz.
  • the test consists of vibrating the cross member, for 200 hours, at the rate of 5 hours per day, and in 30-minute cycles, followed by 15 minutes of rest. At the end of the test, the state of the element tested, in this case the underside of the concrete blocks, is observed.
