Definitions

  • the present invention generally relates to a method of making a walkable platform type track.
  • a walkable platform-type lane in the sense of the present invention is a traffic lane comprising at least one rail integrated in one or more lining plates and capable of accommodating automobile-type road vehicles in addition to vehicles intended to use the rail. .
  • the method of the present invention can be applied to the realization of all concrete channels type walkable platform.
  • the method of the present invention can be applied to the construction of railroad tracks for trams, level crossings crossing a railway, circulable routes inside deposits.
  • the method of the present invention can also be applied to the realization of washing areas on railways or rail tunnel ways when road access must be possible.
  • Circumable tramway platforms are known. These are usually made of two rails and a coating and are subject to various mechanical stresses.
  • the rails support the load of the trams and transmit it to a foundation slab, the covers fill the space between the level of the foundation slab and the high level of the rails and can create in some cases a traffic plan.
  • a first method of producing a circulating platform type circulation lane has been described.
  • the first step of this process is to attach rails to a foundation slab by fasteners.
  • the use of fasteners provides a satisfactory performance of the rails but presents difficulties during the implementation of the method.
  • the fasteners can be associated with a saddle, their holding being provided by the concrete of the foundation slab.
  • the installation of the rails and the slab of foundation must intervene simultaneously which poses difficulties of implementation.
  • This process causes multiple difficulties to protect the insulating elements under platform, set up reinforcement and maintain the device accurately during casting.
  • To these difficulties, is also added the requirement not to mechanically stress the rails and the foundation slab during the setting of the concrete forming the slab and until it reaches sufficient strength.
  • the fasteners described above can also be integrated into prefabricated sleepers.
  • the difficulties of implementing the method come from the precise adjustment of the spacing of the rails, the position of the track and its rigorous maintenance during the placement of the concrete.
  • the track does not support stress during the setting of the concrete and until it reaches a sufficient strength, which lengthens the duration of the sites.
  • the second step of the known method for producing a circulating platform type circulation lane consists in covering the foundation slab with a coating whose upper part will be at the same level as the upper part of the rail.
  • This achievement step also poses difficulties because the compatibility of the coating with the presence of the fasteners is difficult to achieve. Indeed, the thickness of the coating must be reduced at each fastener, which can increase the fragility of the coating at the fasteners. In addition the coating must be deposited to allow the execution of controls on the structure of the fasteners and to carry out their maintenance.
  • a second method of making a circulating platform type circulation lane has been described.
  • This method consists in carrying out a coating of the rail.
  • the coating of the rail can be carried out before the installation of the site.
  • the coating product is bonded to the rail and the holding of the assembly in a setting concrete is ensured by the recesses. the outer profile of the rail coating.
  • This method has several disadvantages.
  • the concrete having no adhesion on the coating it must be reassembled on both sides of the rail which limits the architectural possibilities.
  • the track must be kept in place during the implementation of the concrete and does not support stress during the setting of concrete and until it reaches sufficient strength, which extends the duration of the sites.
  • a production method has also been described in the application DE19519745 filed May 30, 1995.
  • This process consists in casting a concrete around a rail, and finish the realization of the traffic lane by fixing the rail in functional position.
  • adhesion the metal and concrete is ensured by the establishment of a primer, but it is necessary to previously make a groove in which is placed the rail.
  • the geometric tolerances must be as close as possible to the positioning tolerances of the rail, which makes it difficult to achieve and requires oversizing of the groove.
  • step (a) the rail or rails are wedged in a pre-established functional position.
  • a platform comprising one or more coated rails and a coating is produced by coordinating the successive placing of the various elements with the casting of the coating of the rail so that the first part of the casting serves to support the coating slabs and that the slabs serve as a pouring chamber for the upper part of the coating.
  • the implementation of this method makes it possible to prefabricate only standard and simple elements that can be stored without immobilizing a large supply value.
  • the implementation of the method of the invention also allows to take into account the architectural constraints to the edge of the rails.
  • Other advantages emerge from the implementation of the method. Among these advantages include the ability to precisely adjust and assemble the rail by welding when it is without dressing, that is to say when the base is not yet in place.
  • the formwork of the lower part of the wedging is fast and does not risk to disrupt the rail.
  • the casting of the cushioning product does not transmit stress or vibration to the rail which could disrupt it.
  • Taking the coating forming the base is fast and sufficient resistance compatible with the use of the way is obtained in a few hours.
  • the placement of the coating is rapid and the step (d) of casting of the coating product of the rail can be performed immediately after the laying of the coating slab, without additional adjustment of the rail, which allows to complete laying in a few hours.
  • the first step (a) of the method according to the invention consists in wedging one or more rails 1 on a foundation slab 2, in a pre-established functional position.
  • the figure 1 represents an example of positioning two rails 1 on a foundation slab 2.
  • the rail 1 comprises a foot, a head and an intermediate portion joining the foot and the head.
  • the functional position of the rails 1 is defined as being the position compatible with the movement of a train or a tramway for example.
  • the functional position of the rails 1 is achieved using techniques known to those skilled in the art. For example, mannequins can be placed at regular intervals on the rails to ensure proper maintenance and positioning.
  • the dummies are equipped with devices ensuring the vertical and horizontal adjustment of the rails, and ensuring a correct positioning of the rails relative to each other if several of them must be put in place.
  • the second step (b) of the method according to the invention consists in making a coating of the foot of each rail 1 with a material forming a base 3.
  • the upper part of each rail 1 protrudes above an upper part of the base 3.
  • foot of the rail the person skilled in the art include the portion of the rail including the foot and possibly a portion of the intermediate portion of the rail.
  • the base 3 rests on the foundation slab 2 and has an upper surface of sufficient size to be able to serve as a support for a slab of coating 4.
  • the embodiment of the base 3 makes it possible to fix each rail in its operative position to the slab of foundation 2.
  • step (b) of making the base 3 will be described below in more detail.
  • the third step (c) of the method according to the invention consists in placing one or more coating slabs 4 on the base 3.
  • a facing slab 4 can be placed on the upper surface of the base 3 of two parallel rails as is visible on the figure 3 .
  • a facing slab 4 can also be placed between a rail 1 and the edge of the traffic lane under construction as is also visible on the figure 3 .
  • a shim 12 whose thickness is identical to that of the base 3 can be placed near the edge of the track under construction.
  • a shim 12 is however not necessary in the case where it is desired to lay pavement slabs 4 forming a slight slope between the rail and the edge of the taxiway under construction.
  • This casting chamber 5 is formed by the lateral surface of the facing slab 4 facing the projecting portion of the rail 1, and the projecting portion of the rail 1 itself.
  • the bottom of the casting chamber 5 is defined by the upper surface of the plinth 3.

  • the coating material used in step (d) is resilient, and strongly adherent to the rail 1, the concrete constituting the base 3 and the facing slab 4 through the use of a primary hooking.
  • a primer to solve adhesion problems is known to those skilled in the art and will not be described in detail.
  • Step (a) of the described method may be preceded by a step of inserting at least one drain 10 into the foundation slab 2, and or cover them mortar tight mortar mortar as shown on the figure 1 .
  • the drain or drains 10 make it possible to facilitate the flow of runoff water. Drains 10 put in place can also be intended to receive cables.
  • the method comprises an additional step (e) of pouring a setting mortar between the facing slab 4 and the foundation slab 2 as shown in perspective on the figure 8 .
  • This setting mortar is not essential for carrying out the process but makes it possible to increase the mechanical strength of the coating plates 4, especially when they are intended to support road vehicles of the automotive type.
  • the setting mortar may be cast using reservations passing through the facing slab 4 or spaces provided at the time of performing step (c) of laying the facing slabs 4.
  • the step of setting up the coating slab 4 occurs quickly after the beginning of the implementation of the method. Indeed, the casting of rail coating product and wedging between the slabs can be executed immediately without additional adjustment of the rail which allows the laying of the track in a few hours.
  • the thickness of the base 3 made during step (b) of the method can be determined so that the upper surface of the facing slab 4 is at the same level as the upper part of the rail 1 as is visible on the Figures 4 and 4A .
  • steps (i) to (iv) of step (b) are described below in more detail.
  • the formwork elements 61 may for example be composed of a rigid section extending along the entire length of the rail 1 associated with a compressible element 8.

  • the shuttering elements 61 make it possible to define a formwork 6 in which a coating material forming the base 3 will be cast.
  • the jig 7 makes it possible to determine the thickness of the formwork 6 to be made and consequently that of the base 3. In indeed, the thickness of the base 3 made depends on the formwork thickness 6 set up.
  • the jig 7 comprises a horizontal part 70 resting on the upper surface of the head of the rail 1 and two vertical parts, ending with forks 71 intended to fit on the upper parts of the formwork elements 61.
  • the template When the template is put in place during step (b), it is placed on the upper surface of the formwork elements 61.
  • the thickness of the formwork 6 will then decrease by crushing the compressible element 8 to that the jig 7 also rests on the upper surface of the rail 1.
  • the reduction of the thickness of the formwork 6 can be carried out for example by maintaining a vertical force on the jig 7, directed towards the foundation slab 2.
