Definitions
- the invention relates generally to construction methods for concrete structures, in particular railways for train, metro or tram.
- the processes comprising a step of type a / are more and more frequently used because they allow a rate of construction of the concrete block very fast.
- the fresh concrete is continuously molded by a automatic machine following the course of the track to to build.
- the mold includes two grooves which spare engravings in the concrete mass.
- the rails are arranged by sections in the engravings, butt welded, then manually calibrated in height and spacing one by relative to the other, leaving a minimum spacing by compared to the edges of the engravings.
- a resilient material, like resin, is then poured into reglets.
- This technique is fast for laying concrete, but is slow for laying and setting the rails. She is therefore generally reserved for portions of fairly short tracks, such as level crossings.
- the rail coated with a elastic material is first put in place in a trench along the course and calibrated manually according to the expected profile. Then, the construction of the linear massif and the insertion of the coated rail in this massif are performed simultaneously. Fresh concrete is poured in continuous in the trench, along the course, around the prepositioned coated rail.
- This second technique requires creating a trench. In addition, the setting of the rails is slow.
- the invention aims to overcome the problems mentioned above.
- the construction process according to the invention is essentially characterized in that the stages of construction of the linear block and setting of the profile composite are simultaneous.
- the step of fitting the profile composite precedes simultaneous construction steps linear mass and setting of the composite profile.
- the composite profile can be guided laterally during the step of molding the solid linear.
- the composite profile can be guided vertically during the solid molding step linear.
- step b / setting up the profile composite along said predetermined path can understand a section setting operation separated along the said predetermined route and a butt connection operation of these sections separated.
- the fresh concrete can be fluidized mechanically during the solid molding operation linear.
- the composite profile can be lifted and pass through the mass of fresh concrete before simultaneous steps a / and d /.
- the composite profile can be a rail wrapped in resilient material.
- the resilient material can be placed around the rail after step b / and before simultaneous steps a / and d /.
- the composite profile can comprise a metal profile and a filling material.
- the composite profile may include a metal profile, a rail at least partially inserted into the metal profile, and a material resilient filling the metal profile.
- the metal profile can include notched side faces.
- the method according to the invention can be applied to the construction of a railway for a train, a metro or a tram.
- railroad constructed in this way includes a linear massif continuous concrete 10 following a predetermined path, carrying two engravings 12 parallel limited each by lateral edges 13 and a bottom 14.
- two rails 20 are at least partially inserted each in an engraving 12 and positioned precisely for follow a predetermined profile.
- the main parameters by which rails 20 are wedged are the spacing between the rails 20, the height, and the play between the edges 13 of the engravings and the rails 20.
- Cleanliness concrete 15 is first poured along of the route of the track. Then the linear massif 10 is continuously built on the surface of clean concrete 15, using a machine carrying a mold 16 moving along the course. Fresh concrete 17 is pumped or placed in front of the machine, the mold giving it a predetermined shape as and when advancement of the machine.
- the predetermined form is generally substantially rectangular, both engravings 12 being located on an upper face 18 of the linear mass 10.
- the rails 20 are deposited in sections in the engravings 12 and are butt welded.
- these rails 20 are positioned precisely at using wedges, so that they follow the profile predetermined.
- a resilient material 19 is injected into the engravings 12 to fill them up to a level predetermined. This resilient material 19 allows particular to dampen the vibrations caused by the tram, metro or train trains.
- Positioning shims are recycled or lost.
- the stages of construction of the linear massif 10 and setting the rails 20 are simultaneous in each point along the track.
- a concrete of cleanliness 15 is first sank along the predetermined course of the way.
- the rails 20 are then arranged in sections on along this same predetermined route and butt welded end.
- the rails 20 are not stalled at this stage of the process.
- the resilient material 19 is then put in place around the rails.
- This resilient material 19 can be molded on site. It can also be preformed into blocks in the workshop, the rail 20 then being inserted into the block of resilient material preformed by an opening provided at this effect.
- the linear block 10 is constituted and the rails 20 are positioned using a machine 30 which circulates along the route.
- this machine 30 carries a mold 32, a guide system 34 of the rail 20, and two brackets 36 located at the front of the machine following the normal direction of travel of the machine 30, represented by an arrow in Figures 6 and 7.
- the brackets 36 are provided with gripping members 37 of rail 20, sliding along this rail 20 as it goes measurement of the progress of the machine 30.
- These organs of gripping 37 are for example simple hooks.
- a mass of fresh concrete 17 is deposited periodically in front of the machine 30. This fresh concrete passes in the mold 32 when the machine 30 advances and acquires a predetermined shape.
- the fresh concrete 17 used is very dense and very viscous. While in mold 32, this concrete fresh 17 is fluidized by a mechanical device not shown equipping the machine 30. This device can by example be a vibrator. Fresh concrete 17 is distributed thus uniformly in the mold.
- the mold 32 does not contain grooves for create engravings and present a shape section generally substantially rectangular and includes drains 31 at the front.
- the rails 20 coated with the resilient material 19 pass through the fresh concrete 17 deposited in front of the machine 30 and pass through the mold 32.
- These rails 20 are wedged according to the profile predetermined by the guidance system 34 composed of a set of positioning means.
- the distance between the rails 20 is adjusted by two plates 37 carried by an inner face 33 of the mold 32, as shown in Figures 3 and 4.
- Each plate 37 guides a rail 20. They have a different shape depending on the type of rail.
- plate 37 For a "grooved" type rail, comprising a groove 201 as shown in Figure 3, plate 37 carries a pin 371 of a shape corresponding to that of the groove 201. The pin 371 is engaged and moves in permanence along the gorge 201.
- the spacing of the pins 371 of the two plates 37 is very precisely adjusted according to the spacing of wheels of the oars which must run on the track.
- the plate 37 carries a groove 372 facing rail 20 and limited by two flanges 373.
- Rail 20 comprises a head 202, substantially cylindrical.
- the throat 372 is semi-cylindrical and follows the outline of the head 202 of the rail.
- the spacing of the grooves 372 from the two plates 37 is very precisely adjusted according to the spacing of wheels of the oars which must run on the track.
- the plates 37 extend over at least part the length of the machine 30 and are strictly parallel.
- the lateral position of the rails 20 is determined by the lateral position of the machine 30.
- the position side of the machine 30 is checked at all times compared to an external reference 38 which determines the trajectory of the machine 30.
- This lateral position is transmitted to the rails 20 both by plates 37 and by lateral guides 39.
- lateral guides 39 are linked to the mold 32. This are for example pebbles, as shown in the Figure 7, or pads, as shown in the figures 2, 3 and 4.
- Each pair includes two side guides 39 located opposite each side of the rail 20.
- the pads are typically brackets, one of which face 391 is fixed to the underside 33 of the mold 32 and another perpendicular face 392 slides on one side vertical of rail wrapped in resilient material 19.
- rollers have vertical axes and roll on a vertical side of the rail wrapped in material resilient 19.
- the vertical position of the rail 20 can be adjusted by at least two different devices, which can be used jointly or alternatively.
- One or more electromagnets 40 arranged above of the mold 32, as shown in FIGS. 3 and 4, hold the rail 20 pressed against the underside 33 of the mold 32.
- the plates 37 are made of non-magnetic material, like some types of steel.
- Two sets of electromagnets 40 are arranged parallel over the length of the machine 30, above the rails 20.
- guides vertical, skids or rollers 41 represented on the FIG. 6 are linked to the mold 32.
- Each pair includes two side guides 41 located opposite, one above and the other below of rail 20.
- rollers have horizontal axes and roll on a horizontal side of the rail wrapped in resilient material 19.
- the two variant embodiments can be combined and 30 machines can be placed in the machine electromagnets 40 above the rails 20 and the rollers 41 or pads under rail 20.
- Fresh concrete 17 fluidized by the device mechanical mentioned above coats the rails 20 and the resilient material 19, which are engulfed in the massive 10 exactly as if the process of the prior art had been used.
- These metal sections 45 have a U-shaped section open upwards and have vertical blanks 47. They must be filled with filling material to increase the rigidity of the assembly and avoid deformation at the time of installation, in particular due to hydrostatic pressure of fresh concrete on the blanks 47 of the U, of the pressure of the lateral or vertical guides, or due to the action of the gallows.
- the filling material is chosen in such a way so that it can be easily removed and replaced. We can thus create by this process for example gutters where piping or electrical conduits.
- External faces 48 of the vertical blanks of the metal profiles 45 can be notched so as to improve the anchoring of these sections 45 in the concrete.
- the method according to the invention can also be applied by replacing rail 20 with a set comprising a U-shaped metal profile 45, a rail 49 at least partially inserted in the metal profile 45 and a resilient material 50 filling the metal profile 45 up to a predetermined level, as shown in Figure 5.
- the metal U-shaped profile is open at the top.
- the rail 49 can be of the Vignole or grooved type.
- the resilient material is typically a resin.
- the metal profile 45 can be notched on the outer faces 48 to improve the solid anchoring in concrete.
- the mold 32 can be equipped with scrapers and brushes removing traces of fresh concrete deposited on the upper face of the rail.
- This process can be applied to the construction of tram, metro, regional train or mainline trains running up to speeds important, for example 160 km / h.
- Speeds can be achieved with a rectification of channel micro-faults, for example by grinding.
