Problems solved by technology

This leads to an increase in the cost of the obtained system and the quality of the arrangement of the shims depends on the operator
[0007] In addition, this demonstrates that during transport and handling of the system, deformation of the system may cause the shim to disengage from the sleepers

Embodiment Construction

[0026] refer to figure 2 A first embodiment of a sleeper shell system according to the invention is shown. System 10 includes sleepers 12 , housing 13 and rail securing system 14 .

[0027] Rigid crossties 12 are made of concrete, for example. In a first embodiment, the crossties take the shape of a substantially parallelepiped. The sleeper 12 thus comprises a lower side 20 , an upper side 22 and four sides 21 connecting the lower side 20 and the upper side 22 between the lower side 20 and the upper side 22 .

[0028] The upper face 22 of the rigid sleeper 12 includes a region 23 in which the rail fastening system 14 is implemented. exist figure 2 In an embodiment of the present invention, this area 23 is formed by the bottom of a substantially square-shaped recess so as to accommodate a metal plate forming the base 41 of the rail fixing system 14

[0029] The rail fixing system 14 makes it possible to hold the rail 15 in place on the crossties 12 . The rail securing sys...

Abstract

The invention discloses a sleeper shell system for a railway track and a railway track section. The sleeper housing system (10) is fitted in the base of the railway track, the sleeper housing system is of the type comprising a sleeper (12) comprising a lower side (20) and an upper side (22) and a housing ), the upper surface (22) is used to accommodate the rail fixing system (14), wherein the outer shell substantially completely surrounds the sleeper to define the internal storage volume of the sleeper, and the internal storage volume Insulated from external erosion.

Description

technical field [0001] The invention relates to a sleeper shell system for railway tracks and railway track sections. The sleeper housing system is of the type comprising a sleeper and a housing, the sleeper having a lower surface and an upper surface, the lower surface being adapted to receive a rail fastening system. [0002] In this application, a sleeper refers to a part of all types (wooden, metal, concrete) placed perpendicularly to the railroad tracks and used to support the rails, maintaining the spacing and at the same time distributing the load. Thus, a one-piece sleeper supports two rails of two rails, or a double-block sleeper consists of two tie beams each supporting one of the two rails, the two tie beams being connected or not by connecting rods . Background technique [0003] Document FR 2 906 269 A1 discloses a system of the above-mentioned type in which, as shown in FIG. 1 , the casing forms a boot 6 delimiting a housing cavity for the lower part of a sle...
