Definitions

  • the present invention refers to a rail supporting assembly comprising slabs with cushioning elements for fastening thereof to the ground.
  • further cushioning elements may be interposed, underneath and to the sides, between the rail supporing elements and their seats (apertures) formed in said slabs.
  • the main object of the present invention is, therefore, to overcome the above mentioned drawbacks of the prior art, by providing a supporting assembly for railway and/or subway lines made up of slabs having a reduced transmission of stresses to the ground and improved cushioning of vibrations, even those due to lateral or transverse oscillations of the slabs during the passage of carriages on the rails.
  • a further object of the present invention is that of providing such an assembly that leaves escape routes free, and that does not require wider and thus more costly tunnels to be created.
  • Said fastening elements are able to stop longitudinal and/or transverse movements (displacements) of the slabs with respect to the ground, preventing them from shifting with respect to their seat but without impairing their ability to balance (float) in said resting position.
  • Each of said fastening elements is formed by a parallelepiped-shaped rigid central structure fixed to the ground (seat) and an outer rubber part (frame) which laterally surrounds said inner structure and in which each fixing element is housed in a cavity suitably formed in said slabs so that each cavity is a through cavity passing through the thickness of said slabs.
  • Each cavity is preferably formed by two recesses of two adjacent slabs made on the sides of each slab perpendicularly to the direction of movement (longitudinal axis of the rails).
  • each cavity as defined above may be replaced by a through cavity formed completely inside said slabs; or each cavity as defined above may be replaced by a plurality of cavities formed between adjacent slabs or formed completely inside each of said slabs.
  • each of said cavities as defined above may be open at the bottom towards the ground but closed at the top towards the rails.
  • the central part of the fastening element acts as a stopper against movements of the slab in the direction of movement of the train and transversally to said movement whilst the external rubber part which surrounds the central structure acts as a cushioning element for the vibrations generated by lateral oscillations of the slab both in the direction of movement of the train and transversally to said movement.
  • the fastening element or stopper is in contact with the slabs through its elastic frame (outer cushioning rubber) and is fastened to the ground by means of tie bars: there are no other tie bars that fix the slab to the ground so that no tie bars pass through the slab.
  • the number of fastening elements is not binding for the purposes of the present invention.
  • the rails keep the slabs bound to each other, one might think of using a smaller number of the above described cushioning fastening elements than the number of slabs, for example providing for there to be two or more, preferably three, slabs between two fastening elements.
  • stopper every so often (for example one out of ten or even twenty) to allow water to drain easily into the manholes beneath.
  • slab is any block of reinforced concrete on which one or more rail contact and constraining assemblies must be housed. Said blocks of reinforced concrete are constrained to each other by means of the rails which pass from one block to another.
  • rail supporting (or bearing) elements is any element on which a rail may be rested and able also to carry the members for fastening of said rail to said element.
  • These elements may be blocks, sleepers or couplers for rails formed directly with the slab by concrete casting, preferably sleepers, commonly used in the railway and subway field.
  • the sleepers may be standard railway sleepers, of wood, French type twin-block, etc.
  • said slab is generally in the form of a parallelepiped whose dimensions depend upon the characteristics and the type of railway or subway line that is to be built, the dimensions of the fastening element remaining equal.
  • shape of the slab also depends upon the type of supporting element that is chosen in creating the line which will be housed in one or more apertures specially formed in the slab.
  • cushioning elastic elements are also provided, interposed between the seat of the railway structure represented by the excavation in the ground (also known as the slab) and the cement slabs, over which the present slab assembly floats.
  • FIG 1 shows diagrammatically part of an assembly 100 for supporting and fastening to the ground rails of railway and/or subway lines 21, with vibration cushioning, of the present invention, represented for simplicity of the drawing by three slabs (defined also as plates), each designated by the reference numeral 1 and including sleepers 20.
  • Reference numeral 11 indicates a fastening element which is placed between one slab 1 and the other ( Figure 2 ). Beneath each slab 1 there are positioned elastic cushioning elements 9 which in turn rest on the seat 10 of the assembly ( Figure 3a ).
  • each slab can float in its resting position.
  • the seat 10 is created after having carried out the excavation, housed suitable pipes, for example for drainage of rain water, and after having performed compacting operations so as to provide a highly coplanar plane, as illustrated in Figure 3a .
  • FIG 3 shows diagrammatically the part of the assembly 100 illustrated in Figures 1-2 but without sleepers 20 (or ties) and rails 21 and without some fastening elements 11 (those adjacent to two slabs 1) for the sake of simplicity of the drawing.
  • Each of said slabs 1 has a plurality of three housings 2 able to accommodate the sleepers 20 ( Figure 1 ).
  • Each slab 1 further has two C-shaped undercuts 4 cut in the sides 5 perpendicular to the axes 3 of the rails. When two slabs 1 come to be in a position adjacent to one another, the respective C-shaped undercuts 4 form a rectangular cavity 8. Said cavity 8 passes through the thickness of the slabs 1.
  • the fastening element 11 is housed in one or more of said cavities 8 formed by adjacent slabs 1. Said fastening element 11 is only in contact with the undercuts 4 of the slabs as shown in Figure 3 .
  • said fastening element 11 or stopper is in contact with the slabs through its elastic frame (outer cushioning rubber) and is fastened to the ground by means of tie bars.
  • rubber or elastic elements 34 can be inserted between the sleepers 20 and their seat in the slab 1 ( Figure 8 ) in order further to reduce vibrations.
  • Said elements 34 are generally glued around the ends of the sleepers 20 and subsequently said sleepers are laid in the respective housing 2.
  • Said fastening element 11 is formed by an outer rectangular frame 12 made of cushioning elastic material, for example rubber, and the outer profile thereof equal to the size of the cavity 8 formed by the undercuts 4 of two adjacent slabs 1. Any cushioning material used in the art to reduce and/or cushion mechanical stresses and the transmission of vibrations can be used as cushioning elastic material.
  • the thickness of the frame 12 can advantageously range from 20 to 200 mm, for example. In a preferred embodiment the thickness is 40 mm.
  • such an assembly is also advantageous compared with assemblies used for non-subway lines wherein the slabs rest on an underlying concrete slab thanks to the presence of protruding parts suitable to be fixed in the slabs beneath, provided with non through cavities, by means of a groove-and-tongue coupling, so as to obtain fixing of the slab.
  • this embodiment entails long maintenance operations in view of the need to lift the slab to gain access to the underlying concrete slab.
