Definitions

  • the present invention relates to a method allowing the construction of works such as railway, motorway, road or pedestrian crossings through any embankment or earthworks supporting one or more railways, without requiring the prolonged stopping of traffic flowing on these tracks.
  • the present invention relates to a method which makes it possible to avoid the drawbacks of the solutions recalled above, by ensuring the realization under the embankment or more generally the support structure of railways or the like, of a road or pedestrian crossing without require a long-term interruption of traffic, which is easy to implement and which entails only reduced costs, whatever the transverse dimensions of the work to be carried out.
  • the process considered is characterized in that it consists of driving transversely in a manner known per se, under the slope, two pairs of half-abutments or straight hollowed feet, arranged two by two opposite one another and on the other side delimiting the passage to be produced and providing beneath the tracks, between them and the upper face of the half-abutments, a limited fill thickness, to bring the half-abutments two by two in abutment substantially in the plane longitudinal median of the slope, to wedge these half-abutments in their mutual junction zone on either side of this median plane, to be fitted in place under the stiffener tracks over a length of these slightly longer than that which separates the two pairs of half-abutments, before or after the sinking of these, to remove the fill between the tracks and the abutments abutting under the stiffeners, to be placed on the two pairs of half-abutments respectively two so mmiers supports resting on these half-abutments, to remove the stiffeners and then to cut the tracks on a length corresponding to
  • the driving of the two half-abutments of each pair is carried out using cables crossing the slope, each fixed at one end to a half-abutment and secured to the other end of a jack bearing on the other half-abutment and exerting on the cable a tensile force ensuring the mutual approach of the half-abutments.
  • the two half-decks are produced by pouring concrete on either side of the slope on scaffolding extending parallel to the tracks and surmounting the two half-abutments of the two pairs, arranged on each sides of the slope.
  • the casting and drying of the half-decks is carried out during the sinking operations of the half-abutments in the slope.
  • the method according to the invention thus allows an optimal organization of the successive operations to be carried out, among which the cutting of the tracks and the interruption of the traffic which results therefrom are reduced to the minimum, corresponding to the only installation of the half-decks, -same previously built to the dimensions exactly provided on either side of the slope during the prior operations of sinking the half-abutments, reinforcing the tracks and making the box springs intended to receive these decks.
  • the method of the invention makes it possible, without having to cut the tracks, to produce under them, in the limited space available between the upper face of the half-abutments once joined and the tracks themselves, the box springs support for aprons.
  • the box springs are poured in place or the prefabricated box springs are sealed on the half-abutments so as to make up for any misalignment of the contiguous faces of the half-abutments.
  • the half-decks are previously built on the two box springs which are ripped with the decks on the half-abutments under the tracks.
  • the invention consequently provides both a very great economy in the handling and manufacturing means necessary for the implementation of various stages of the process envisaged, and also a speed in the accomplishment of these stages, by authorizing consequently a particularly significant reduction in the total cost of these operations. It should be emphasized that all these stages enter into the final construction of the structure, which is an additional factor of economy, compared to all the other methods which introduce additional stages which affect the overall cost of the structure.
  • an embankment for supporting one or more railway tracks has been designated under the reference 1.
  • this embankment, as well as the nature or the arrangement tracks 2 have no direct impact on the implementation of the method according to the invention, which can be applied identically to make a passage under any earthwork supporting different tracks, even if its application to railways seems particularly advantageous.
  • pairs of hollow half-abutments or straight feet 3 and 4 respectively, arranged on either side of the slope 1, are used.
  • half-abutments with a hollow structure 5 ( Figure 5) allowing in particular, once the work is completed and as will be seen below, pedestrian traffic for example, the space provided between the abutments of two neighboring pairs being reserved for vehicles.
  • the half-abutments 3 and 4 in each pair are joined in pairs through the slope 1 by means of prestressing cables 6, each fixed at one end 7 to one of the half-abutments 3 and to the other on a hydraulic or other cylinder 8, carried by the facing half-abutment.
  • the number of cables 6 thus connecting the two half-abutments is chosen according to the efforts to be developed to ensure the sinking of one towards the other through the ground of the slope 1 so as to bring these elements together and gradually one the other.
  • the soil 9 which progressively fills the internal hollowed out part 5 of the half-abutments during their respective advances is continuously evacuated by an excavator belt 10 or by any other suitable earthmoving means. It will be noted in this regard that this technique of mutual sinking of hollow structures towards each other is now known in the art but results from work and publications of the applicant.
  • these half-aprons is again without direct impact on the implementation of the method.
  • they can be partially or completely prefabricated and brought directly by appropriate handling equipment to their scaffolding, or else be built directly on them, taking advantage of the time necessary for driving the abutments for their manufacture and in particular if they are made of poured concrete, for sufficient drying thereof.
  • each box spring transverse to the tracks if necessary having a lateral reinforcement 23 preventing the earth spoil from collapsing on the bed base itself.
  • This box spring 22 can be produced by means of a prefabricated element riped on site or manufactured in situ with adequate dimensions corresponding to the width of the two half-decks 12 and 13. Possibly, and as already said, the installation of the bed base 22 can be carried out with a backlash at the junction of the two corresponding half-abutments 3 and 4.
  • the tracks 2 are then sectioned between the box springs 22 thus produced on the half-abutments of the two adjacent pairs delimiting the width of the passage to be carried out, then the fill 24 is removed above the plane 16 of the abutments in order to allow, by any suitable conventional means, to cause the half-aprons 12 and 13 to slide towards each other by bringing them, at the end of the race, to rest on the box springs 22 whose spacing has been exactly determined beforehand (FIGS. 3 and 4).
  • FIG. 3 As a variant, and as schematically illustrated in FIG.
  • the box springs 22 and the aprons 12 and / or 13 can be made one and the other outside the track and then, once these aprons resting on the box springs, riped together under tracks 2 on the corresponding half-abutments.
  • a work of art is thus produced, in particular a passage under rolling tracks, under conditions which, while providing security for the subsequent flow of traffic on these tracks, allow a saving of time and an economy of means particularly appreciable.
  • the invention can naturally be adapted to particular geometries of works and / or railways, without modifying the general principles of its implementation which in all cases lead to a quite significant reduction in the time when the tracks are unavailable, all operations before and after this single step in the process being carried out without interrupting traffic.
  • the mean inclination of the front-nozzles 26 is here chosen equal to 45 °, which makes it possible to maintain a slope of 3/2 during the earthworks of the working face being sinking of the half-abutments in the manner specified above. This results in a significant reduction in the depth theoretically necessary in the case of a single slope forearm, in order to ensure the stability of the slope 1 during this driving.
  • each half-abutment comprises at the level of the separation of its successive stages 3a, 3b or 4a, 4b, an intermediate slab 28, suitable for serving as a strut when the half-abutments are approached and keyed together, allowing reduce the amount of steel required to hold the right feet.
  • an intermediate slab 28 suitable for serving as a strut when the half-abutments are approached and keyed together, allowing reduce the amount of steel required to hold the right feet.
  • the splitting of the half-abutments with serrated front-beaks 26 it can be seen that only the lower tooth 26b penetrates, at the start of the sinking operation in the slope 1.
  • the backfill load at - Above this front spout is therefore relatively more limited, which reduces the risk of lifting when the force necessary for driving is exerted.
  • the upper front spout 26a by itself provides a permanent overload on the lower stage directed downwards, which avoids the risk of lifting when the corresponding half-abutment advances.
  • Another improvement usefully envisaged consists in arranging the front-nozzles 26 of the half-abutments 3 and 4 so as to facilitate the advance of these in the thickness of the slope 1, during the sinking operation of these half-abutments.
  • the front spout is constituted, as illustrated in FIG. 10, by means of a T-section 29, on which is welded at one of its ends a flat iron 30, slightly sloping with respect to the profiled, so as to pack the ground over a limited thickness, for example of the order of 2 cm.
  • This mud is advantageously brought into place by a tube 32, embedded in the concrete 33 of the half-abutment, between the reinforcing bars 34, and connected at its opposite end (not shown) to a low pressure pump.
