Description

"MODULE OF CANIVEAU FORMING RETAINING WALL FOR THE PRODUCTION OF A FUNCTIONALIZED CANIVEAU NEAR A CIRCULATION PATH" The invention mainly relates to a channel module for making a gutter located near a traffic lane rail or car.

The invention also relates to a gutter made by implanting end to end a plurality of such modules.

[0003] The traffic lanes require a number of equipment to ensure their operation.

Referring to Figure 1 which illustrates two railroad tracks cuttings of the prior art, there are the tracks 1, 2 with rails and sleepers, and the ballast bench 3,4 on the floor 5 which stabilizes the concerned track 1,2 and diffuses the forces exerted by the vehicles in circulation.

When two parallel paths 1,2 are located at different heights and it is impossible to arrange a slope between these two lanes 1,2, either because of the importance of the cant, or because of insufficient space between these two lanes 1,2, a retaining wall 6 allows to take this difference in height of land. In order to avoid the accumulation of water at the level of the highest channel 1, it is possible to provide barbacan-forming orifices 7 which evacuate the water from the uppermost channel 1 towards the lowest channel 2 to prevent their accumulation. .

It is also provided a cable duct 8 which protects the cables that serve the different equipment and is made of an end-to-end assembly of U-shaped reinforced concrete modules closed at the top by a cover 8a .

It is further provided, next to the cable duct 8, a water gutter 9 which ensures the drainage of water collected under the channels and evacuation of collected water. The water channel 9 is made of an end-to-end assembly of modules also in U-shaped reinforced concrete, closed at the top by a cover 9a. Generally, the water channel 9 has a greater depth than the cable duct 8.

The lids 8a, 9a cable gutters 8 and water 9 form a track for agents to walk safely along the tracks.

On the other side of the cable gutters 8 and water 9 and opposite the channels I, 2 are arranged poles, for example signaling 10 and catenary II, which are fixed to the ground 5 by means of foundation blocks 12,13 forming the connection between the post and the ground.

Finally, all these devices are arranged around the tracks to leave free the necessary volume, called template 14.15, for the circulation of railway vehicles on lanes 1,2.

The various equipment described are juxtaposed with each other. This arrangement requires the creation of an expanded right-of-way around the traffic lanes to allow the installation of the retaining wall, the cable duct, the water channel and the foundation blocks. In addition, this provision requires the intervention of a large number of people during the installation or maintenance of all these equipment. In addition, the realization of all these equipment must be made to measure respecting the configuration of the tracks.

In addition and as shown in FIG. 2, when the retaining wall 6 is made by juxtaposition without prefabricated element connection 6a, the differential settlement between two adjacent elements 6a and / or the thrust of the soil lands 5 can lead to a shift of the elements relative to each other. The elements 6a are no longer aligned; this phenomenon is called the phenomenon of strumming.

When a cable duct 8 is disposed against the retaining wall 6, the continuity of the gutter considered can be degraded and damaged cables. When a water channel 9 is disposed against the wall 6, it is then the hydraulic continuity of the flow that can be deteriorated.

The invention aims first of all the realization of a functionalized gutter to limit the width of the footprint around the tracks. The functionalized gutter will be able to take the difference in height of earth.

The invention further provides the realization of a functionalized gutter to avoid the phenomena of strumming previously explained.

The equipment of the invention will meet the requirements of water drainage and secure circulation of cables along the tracks.

The gutter of the invention must be easily visited and generate the least possible maintenance operations. The gutter of the invention will also allow to improve the installation and maintenance of equipment, both in terms of duration of intervention as the number of stakeholders.

For this purpose, the gutter module of the invention intended to form a gutter functionalized by the end-to-end implantation of a plurality of said modules near a rail or automobile traffic lane, is essentially characterized in that it comprises first and second parallel longitudinal main walls interconnected by a first bottom wall defining the bottom of a water channel module, and in that one of the two longitudinal main walls is greater height than the opposite longitudinal main wall forming retaining wall.

The invention also relates to a functionalized gutter located near a rail or automobile traffic lane, which is essentially characterized in that it is realized by the end-to-end implantation of a plurality of gutter modules such as As previously described, other characteristics and advantages of the invention will emerge clearly from the description which is given below, by way of indication and in no way limiting, with reference to the appended figures among which: FIG. described schematically illustrates two traffic lanes and their associated equipment of the prior art, - Figure 2 already described diagrammatically illustrates a retaining wall of the prior art subjected to the phenomenon of strumming, - Figure 3 schematically illustrates in perspective a module of a gutter of the invention forming a retaining wall according to a first variant in which said module 4 is a diagrammatic perspective view of a channel module of the invention forming a retaining wall according to the first variant in which the front and rear slices of the module are in the form of an arc of gutter.

With reference to FIG. 3, the water or cable duct module 20a of the invention according to a first configuration and a first variant is made of reinforced concrete and has a general U-shaped shape consisting of a first main longitudinal wall 21, a second longitudinal main wall 22 opposite and parallel to the first wall 21, the first 21 and second 22 walls being interconnected by a first bottom wall 23 which defines the bottom of the channel module to water or cable 20a.

According to the invention, one 22 of the two longitudinal main walls 21,22 is of greater height than the opposite longitudinal wall 21. The channel module 20a and the gutter of the invention produced by the implantation into end-to-end gutter modules 20a also form retaining wall 24 to take the difference in height of land on either side of the gutter and support associated overloads.

The longitudinal wall 22 forming a retaining wall 24 has on its inner face a rod 26 which, associated with the upper edge 27 of the opposite longitudinal wall, provide the apposition and maintenance of a lid not shown which the end-to-end assembly defines a track usually referred to as an electrical signaling track or an SE track on which maintenance agents, and in particular electrical signaling service agents, can move. The rod 26 can be attached to the longitudinal wall 22 forming the retaining wall 24.

Referring to Figure 4, the channel module 20b is similar to that shown in Figure 2 in that it has a generally U-shaped being composed of a first longitudinal main wall 21, a second longitudinal main wall 22 opposite and parallel to the first wall 21, the first 21 and second 22 walls being interconnected by a first bottom wall 23 which defines the bottom of the water channel module or cable 20b.

Also, one 22 of the two longitudinal main walls 21,22 is of greater height than the opposite longitudinal wall 21 forming retaining wall 24. In addition, the longitudinal wall 22 forming a retaining wall 24 comprises on its inner face a rod 26 which, associated with the upper edge 27 of the opposite longitudinal wall, provide the apposition and maintenance of a lid.

At least one of the longitudinal main walls 21,22 may comprise a plurality of through holes 28 ensuring the drainage of water flowing under the traffic lanes. There is provided at these openings 28 forming barbican the presence of a draining material, for example a large particle size embankment material such as ballast or aggregates, protected by a geotextile. The drainage orifices 28 are regularly distributed over the longitudinal wall considered 21 over the entire height of the water channel module 24. These drainage orifices 28 may advantageously be distributed over the longitudinal wall 22 forming a retaining wall 24 in order to prevent accumulation of water on the ground or the highest way.

It is further provided in the upper portion 21a, 22a of each of the two longitudinal main walls 21,22 a reservation 29,30 made of an area of thinner thickness than the rest of the longitudinal wall 21,22 concerned. This reservation 29,30 is said to be knockable because its thin thickness makes it possible to easily make a through hole even manually. These knockouts 29,30 allow to circulate a cable not shown from the channel module 20b to a secondary gutter to supply the various facilities near the tracks.

In this configuration, the gutter module 20b extends longitudinally from a front slice in a circular arc 33 to a rear slice 34 also in a circular arc parallel to the front wafer 33. The term slice before 33 and rear slice 34 of the channel module 20b all the slices of the longitudinal walls 21, 22 which open at the front and rear ends of the channel module 20b. The entire front 33 and rear 34 slices of the channel module 20 must be in an arc to allow full surface contact support between the front edge 33 of a first channel module 20b and the rear edge 34 of a second channel module 20b positioned in front of the first channel module 20b. This arcuate configuration of the front 33 and rear 34 slices of each channel module 20b makes it possible to assemble the modules of the invention end-to-end either in a straight line or in curves, while in all cases conserving a geometrical continuity between the modules 20.

In addition and in the context of the invention, this configuration of the front 33 and rear 34 edges arcuate prevents the stripping phenomena observed in the equipment of the prior art. Indeed, if a module 20b tends to shift from the alignment of the other modules 20b, the contact support between two adjacent modules 20b persists through the arcuate slices which allows to distribute the forces and reduce the displacement relative of these modules 20b relative to each other. In addition, the visual appearance of an aligned gutter is preserved.

The channel module 20c according to a second variant shown in Figure 5 is almost identical to that of Figure 4 in addition to the fact that it further comprises a second bottom wall 34 which extends parallel and at a distance of the first bottom wall 23 between the two longitudinal main walls 21,22. This second bottom wall 34 defines the bottom of a cable duct module 35 which is also delimited longitudinally by the respective upper portions 21a, 22a of the two longitudinal main walls 21,22. The second bottom wall 34 also forms a mechanical support buton of the channel module 20c to maintain the two longitudinal main walls 21,22 parallel resistant to lateral thrusts land.

In case of severe weather, a plurality of through holes 36 are provided in the bottom 34 of the cable duct 35 to prevent excessive accumulation of water in the water channel 38. Reservations 37 are also provided in the upper portion 21a of at least one 21 of the longitudinal main walls 21,22 for guiding the water accumulated in the water channel 38 and in the cable duct 35 outside the channel module 20c avoiding the overflows of water on the soil surface.

In this configuration, the gutter module of the invention 20c advantageously forms water gutter, cable duct and retaining wall, while avoiding the phenomenon of strumming.

The channel module 20d according to the second variant and in another configuration shown in Figure 6 largely takes the elements of the channel module 20c of Figure 5, further presenting a waterproof formwork 40 for fixing a post particular catenary or signaling, delimited by a third bottom wall 41 which extends parallel to and away from the second bottom wall 34 between the two longitudinal main walls 21,22, and the respective upper portion 21a, 22a two longitudinal main walls 21,22. It should be noted that this third bottom wall 41 also forms a mechanical support buton in addition to the second bottom wall 34. The formwork 40 is thus located above the cable duct 35 making, in this configuration, the gutter to cables 35 not visitable when removing the cover not shown. The waterproof formwork 40 receives an unrepresented reinforcement network for positioning anchor rods. Once the concrete has poured into the formwork 40 and hardened, a standard plate forming the base of the catenary or signaling pole is secured to the concrete by bolting the anchor rods trapped in the concrete.

In this configuration, the module 20d does not have a lid and therefore there is no provision for a support rod on the longitudinal wall 22 forming a retaining wall 24. Such a channel module 20d advantageously forms a water channel, cable channel, anchoring means and retaining wall, while avoiding the phenomena of strumming.

Referring to Figures 7 and 8, the channel module of the invention 20e, 20f according to a third embodiment is also made of reinforced concrete and includes a large number of elements common to the channel modules 20a, 20b , 20c, 20d of the first and / or second variants. These common elements are referenced identically to the first and / or second variants and are not described again. These are the two main longitudinal walls 21,22, the first bottom wall 23 forming the bottom of the water channel module 38, through openings 28 ensuring the drainage of water flowing under the traffic lanes, reservations 37 to guide the water accumulated in the water channel 38 and in the cable duct 35a outside the channel module 20e, 20f avoiding overflowing water on the ground surface, and knockouts 29,30 to make run the cables to secondary gutters. All these elements comprise only a simple adaptation to the width of the channel module 20e, 20f according to the third variant. As for the module of the invention 20a, 20b, 20c, 20d of the first and second variants, the front 33 and rear 34 slices of the channel module 50 may be straight or in parallel arc to ensure their nesting when the modules 20e , 20f are placed end to end to form the gutter of the invention and avoiding the phenomenon of strumming.

In this third embodiment, the cable duct 35a extends over only a portion of the width of the channel module 20e, 20f. It is delimited for this purpose by the upper part 21a of the first longitudinal main wall 21, by a second bottom wall 34a which extends parallel and at a distance from the first bottom wall 23, and by a third longitudinal wall 45 which extends parallel to the first 21 and second 22 main longitudinal walls from the second bottom wall 34a to the cover 52. A plurality of through orifices 36a are provided in the bottom 34a of the cable duct 35a to prevent excessive accumulation of water in the water channel 38 and allow the evacuation via the reservations 37. There are two stops 53 of which only one is visible in Figure 7 to ensure the mechanical strength of the channel module 20e, 20f and more particularly cable duct module 35a. These two stops 53 extending transversely from the third longitudinal wall 45 to the second longitudinal main wall 22 which does not fit into the cable duct module 35a. These two stops 53 extend in the transverse extension of the second bottom wall 34a of the cable duct module 35a, this second bottom wall 34a also having the function of bumpers.

According to the invention, one 22 of the two longitudinal main walls 21,22 is of greater height than the opposite longitudinal wall 21. It may be one or the other of the two longitudinal walls 21 22. The channel module 20a and the gutter of the invention produced by the end-to-end implantation of the channel modules 20a thus form a retaining wall 24 making it possible to take up the difference in height of the lands on either side of the gutter and to support the associated surcharges.

The longitudinal wall 22 forming a retaining wall 24 has on its inner face a rod 26 which, associated with the upper edge 27 of the opposite longitudinal wall, provide the apposition and maintenance of a lid whose assembly in end-to-end defines a track usually referred to as the Electrical Signal Track or the SE track on which the maintenance agents, and in particular the Electric Signaling Services agents, can circulate.

The lid 52 of the module of the invention 50 of this second variant is composed of three elements of lids 52a, only one of which is shown in FIG. 7. As for the first variant, each lid element 52a also has front 52a 1 and rear 52a2 slices in a parallel arc allowing in particular to cooperate vertically with the front 33 and rear slices 34 of the channel module 50 on which the cover 52 is assembled. The cover member 52a abuts on the upper edge 27 of the first longitudinal wall 21 and on the strip 26 of the opposite longitudinal wall 22 forming a retaining wall 24. The cover member 52a is laterally held by four longitudinal grooves 52a3 only three of which are visible in Figure 7 which are formed on the underside of the cover member 52a and which are positioned and dimensioned to abut respectively against the inner face of the longitudinal main walls 21,22 and sides and else against the third longitudinal wall 45.

According to this second embodiment, a longitudinal rib 54 is formed on the upper face of the cover 52 to allow the cutting of the cover 52 at the third longitudinal wall 51 and allow to inspect either the cable duct 35a either the water channel 38 according to the portion of the cover 52 which is removed, or to provide a pole fastening formwork as will be described later.

Thus, and unlike the channel module 20c, 20d of the second variant, it is possible to visit the water channel 38 by removing the part of the cover concerned 52.

Referring to Figure 8 and similarly to the channel module 20d of the second variant in its second configuration, the channel module 20f can integrate a waterproof formwork 40a for fixing a particular catenary pole or signaling. This formwork 40a is then delimited by the third longitudinal wall 45, the second longitudinal main wall 22 and a third bottom wall 41a which extends in the continuity of the second bottom wall 34a forming the bottom of the cable duct module 35a. . This third bottom wall 41a then forms a mechanical holding stop of the entire channel module 20f.

The formwork 40a has the same functionality as the formwork 40 previously described for the second embodiment. In this configuration, the water channel module 38 is not visitable. As for the second variant, the front face 55a and the rear face 55b of the formwork 40a are part of the continuity in the form of an arc of the front and rear edges 33 and 33 of the channel module 50.

Referring to Figure 9, the end-to-end implantation of the channel 20e modules of the invention according to the third embodiment to visit the water channel 36 form the gutter of the invention 60 which extends along a traffic lane 61. In the configuration shown in this figure, the gutter of the invention 60 is rectilinear. One of the channel modules 20f comprises a formwork 40a as described with reference to FIG. 8 and makes it possible to seal a post 62 of catenary or signaling.
