o On a represente sur la figure 1 une structure conforme a ['invention en place sur son site. Wile assure la continuite de la vole superieure VS, tout en ouvrant un passage transversal a la vole inferieure VI. Dans cet exemple, la vole superieure est une vole de chemin de fer et la vole inferieure est une vole routiere. La largeur de la structure est determinee par celle de la vole s superieure. La structure est constituee d'une partie en forme de portique avec deux piedroits 11 et 13, elements formant des supports verticaux, relies par une traverse superieure 15. La distance separant les deux piedroits correspond ici a la largeur de la vole inferieure. De part et d'autre du portique, la traverse 15 se prolonge dans son plan par deux travees o supplementaires, 17 et 18, en direction de la vole VS. La longueur des o There is shown in Figure 1 a structure according to the invention in place on its site. Wile ensures the continuity of the upper flight VS, while opening a transverse passage to the lower flight VI. In this example, the upper flight is a railway flight and the lower flight is a road flight. The width of the structure is determined by that of the upper fly. The structure consists of a portico-shaped part with two legs 11 and 13, elements forming vertical supports, connected by an upper cross member 15. The distance separating the two legs corresponds here to the width of the lower fly. On either side of the gantry, the crosspiece 15 extends in its plane by two additional spans o, 17 and 18, in the direction of the flight VS. The length of

travees est determinee en relation avec la pente du talus que l'on a degage. travees is determined in relation to the slope of the slope that has cleared.
La pente est comprise entre 30 et 45 . Comme on le volt, les piedroits l l The slope is between 30 and 45. As we volt, the feet l l
et 13 reposent sur le sol par des semelles 1 1 1 et 131 de largeur appropriee. and 13 rest on the ground by soles 1 1 1 and 131 of appropriate width.
La structure dans son ensemble, c'est a dire les piedroits avec leur semelle et la traverse avec ses travees d'approche est realisee en beton, pouvant etre en beton de faible densite, de type beton leger, ou bien en beton fibre, de type BFUP. En effet, la structure est ainsi plus legere, done plus facile a mettre en place. Le cas echeant, en fonction des dimensions, les differentes The structure as a whole, that is to say the legs with their sole and the crosspiece with its approach spans, is made of concrete, which can be made of low density concrete, of light concrete type, or of fiber concrete, of BFUP type. Indeed, the structure is thus lighter, therefore easier to set up. If necessary, depending on the dimensions, the different
o parties vent renforcees par des nervures permettant de raidir la structure. o wind sections reinforced with ribs to stiffen the structure.
Conformement a un mode de realisation, la traverse l S ainsi que les travees supplementaires 17 et 18 vent realisees en beton precontraint ou en In accordance with an embodiment, the cross member l S as well as the additional spans 17 and 18 made of prestressed concrete or in
poutrelles enrobees de beton.beams coated with concrete.
Les travees d'approche s'appuient a leur extremite sur des semelles, 19 et 21 respectivement, qui reposent en crete de talus et s'etendent en travers de la vole VS. On volt sur les figures 2 et 3, le detail de cette partie pour la travee 17. La semelle 19 forme une assise prefabriquee en beton arme, sensiblement parallelepipedique, avec une surface superieure d'appui pour ltextremite de la travee 17. Celle-ci presente ici des plots verticaux 171 d'appui. Pour rattraper les jeux a ['installation, notamment lorsqutil y a tassement du sol, on insere des cales metalliques 194 entre une platine 193 solidaire de la semelle et un coussinet, par exemple en caoutchouc frette 191, engrave dans le plot 171. Une tole laterale 173 reglable en hauteur est placee verticalement en tete de la travee. Wile sert a retenir le materiau de The approach spans are supported at their ends on footings, 19 and 21 respectively, which rest at the crest of the slope and extend across the VS flight. On volts in Figures 2 and 3, the detail of this part for the span 17. The sole 19 forms a prefabricated seat in reinforced concrete, substantially parallelepipedic, with an upper support surface for the end of the span 17. The latter here presents vertical support pads 171. To make up for play at installation, in particular when the ground is compacted, metal shims 194 are inserted between a plate 193 secured to the sole and a pad, for example made of hoop rubber 191, etched in the block 171. A sheet side 173 adjustable in height is placed vertically at the head of the span. Wile is used to retain the material of
comblement et eviter qutil passe sous la travee. filling and avoid it going under the span.
Pour faire face a d'eventuels tassements plus importants, et assurer la o reprise des charges verticales, on prevoit la possibilite de mettre en place des micro-pieux 192 au travers de reservations circulaires menagees dans la To cope with possible larger settlements, and to ensure the resumption of vertical loads, provision is made for the possibility of installing micro-piles 192 through circular reservations arranged in the
semelle et la travee, afin de venir s'appuyer directement dans le sol. sole and span, in order to come to rest directly in the ground.
La pente des talus menages sous les deux travees supplementaires, pendant les travaux de terrassement au moment de la mise en place de la structure peut etre trop raide pour assurer une stabilite suffisante vis-a-vis des risques de gl is sement. Afin de remedier a ce prob leme, on real ise alors une coque en beton projete arme. On peut aussi proceder a un clouage de la paroi du talus, monter un mur poids ou bien le cas echeant remblayer completement o la travee apres la periode d'interception des circulations. Si cela apparat s necessaire en fonction de la nature du sol et de la geometric du talus, on peut monter un mur de maintien des terres dans le prolongement des piedroits. Le renfort au moyen d'une coque en beton arme presente l'avantage d'etre mis en ccuvre rapidement pendant les operations de coupure. Il peut etre utilise de maniere definitive. Il peut aussi etre mis en place de maniere provisoire. Il a alors pour but d' assurer la stabilite du talus, pendant les premiers j ours qui suivent la mise en service de l'ouvrage d'art sous charge o d'exploitation reduite, avant d'effectuer des travaux de renforcement plus The slope of the embankments under the two additional spans, during earthworks when the structure is put in place, may be too steep to ensure sufficient stability with regard to the risk of slippage. In order to remedy this prob leme, one realizes a hull in reinforced concrete. One can also proceed to a nailing of the wall of the slope, to mount a wall weights or else the case, to backfill completely or the span after the period of interception of the circulations. If this appears necessary depending on the nature of the soil and the geometry of the slope, we can mount a wall retaining the land in the extension of the feet. Reinforcement by means of a reinforced concrete shell has the advantage of being implemented quickly during cutting operations. It can be used definitively. It can also be temporarily installed. It then aims to ensure the stability of the embankment, during the first days after the commissioning of the structure under reduced load or exploitation, before carrying out more strengthening work.

On a represente sur la figure 4, une variante selon laquelle les travees 17' et 18' vent en appui sur des tubes metalliques 23 et 25 qui s'encastrent a la s base des piedroits 11' et 13'. La charge des travees supplementaires est There is shown in Figure 4, a variant in which the channels 17 'and 18' wind bearing on metal tubes 23 and 25 which fit at the base of the legs 11 'and 13'.

Si le sol d'assise est mediocre, un racier de liaison est confectionne entre If the seat floor is poor, a connection racer is made between
les piedroits, apres mise en place du portique. the legs, after setting up the portico.
On decrit maintenant un procede de mise en place de la structure conforme a ['invention, en se referent a la fgure 5. Une fois que la structure a ete prefabriquee, on la prepare pour son deplacement jusque sur son site. Dans ce but, on la renforce provisoirement en placant des butons metalliques B 1 et B2. Les butons B1 s'appuient par une extremite sur la base des piedroits 11 et 13. Ils s'encastrent par leur autre extremite sous les travees 17 et 18 a proximite de leur extremite. Ainsi le poids est-il reporte sur la base des piedroits. Les travees ne restent pas en porte a faux. Les butons horizontaux B2, places entre les deux piedroits 11 et 13 au niveau de leur base, o equilibrent les charges. On a place deux series de consoles metalliques C1 et C2 ou tout autre bati provisoire, sur la largeur des piedroits. Des modules de charge, M1 et M2, avec verin vertical viennent en prise sous chacune des consoles, et exercent une force dirigee vers le haut. Ces modules reposent sur des longrines L1, L2 posees sur le sol parallelement entre elles, dans la direction du deplacement a operer. Selon cette technique de ripage, connue en soi, les modules de charge soulevent la charge constituee par l'ouvrage d'art. Ils vent pousses par des verins horizontaux qui prennent appui sur les longrines L1, L2. Les modules de charge glissent sur les longrines grace a la mise en ceuvre de materiaux a faible coeffcient de We will now describe a process for setting up the structure in accordance with the invention, referring to figure 5. Once the structure has been prefabricated, it is prepared for its displacement as far as its site. For this purpose, it is provisionally reinforced by placing metal struts B 1 and B2. The struts B1 are supported at one end on the base of the legs 11 and 13. They are fitted at their other end under the spans 17 and 18 near their end. So the weight is transferred to the base of the legs. Traverses do not remain cantilevered. The horizontal struts B2, placed between the two legs 11 and 13 at their base, where the loads are balanced. Two series of metal consoles C1 and C2 or any other temporary structure are placed, across the width of the legs. Load modules, M1 and M2, with vertical actuator engage under each of the consoles, and exert a force directed upwards. These modules rest on sills L1, L2 placed on the ground parallel to each other, in the direction of the movement to be operated. According to this shifting technique, known per se, the load modules lift the load constituted by the structure. They are pushed by horizontal cylinders which are supported on the sills L1, L2. The load modules slide on the sleepers thanks to the use of materials with a low coefficient of
frottement ou bien de coussins d'air. friction or air cushions.

On a prepare par ailleurs le sol pour la reception de la structure, selon le We also prepared the ground for the reception of the structure, according to the
profl represente sur la fgure. Par exemple, les talus ont une pente de 45 . profl represents on the fgure. For example, the slopes have a slope of 45.
Selon le mode de realisation represente, une fois les travaux preparatoires s effectues, on place les semelles 19 et 21 sur la crete des talus au moyen d'une "rue, puis on approche la structure par ripage. Lorsque l'ouvrage est en place et descendu a son niveau defnitif, on comble les espaces restes vices. On injecte un coulis de ciment au travers des semelles des piedroits et des semelles en crete de talus, par des tubes noyes dans le beton. Au o niveau de la crete des talus, on comble les extremites superieures de l' excavation avec par exemple de la grave-ciment ou tout autre materiau de comblement pour permettre le retablissement de la continuite de la plate forme de la vole portee. Le cas echeant, apres une periode d'utilisation a charge reduite, on reprend les jeux dus au tassement du sol. On introduit un verin 195 entre la semelle et l'extremite de la travee pour soulever According to the embodiment shown, once the preparatory work is done, place the footings 19 and 21 on the crest of the slopes by means of a "street, then approach the structure by sliding. When the structure is in place and down to its final level, we fill in the remaining defective spaces. We inject a cement grout through the footings and crest of footings, by tubes embedded in concrete. At o level of the slopes , we fill the upper ends of the excavation with, for example, gravel cement or any other filling material to allow the restoration of the continuity of the platform of the flight carried. The case, after a period of use at reduced load, the games due to soil compaction are resumed. A 195 jack is introduced between the sole and the end of the span to lift
legerement celle-ci et pouvoir glisser une cafe 194 d'epaisseur appropriee. slightly and be able to slide a coffee 194 of appropriate thickness.
Sur la figure 6, on a represente un autre mode de deplacement de la structure qui comme dans le cas precedent a ete renforcee au moyen de butons B1 et B2. On procede par roulage, qui est egalement une technique de deplacement de charges lourdes connue en soi, par exemple de type chariots automoteurs. L'ouvrage est souleve et deplace jusqu'a sa position defnitive au moyen de chariots automoteurs CA, ici 4, disposes cate a cote a l'interieur du portique entre les piedroits. Ils vent couples, notamment In FIG. 6, another mode of displacement of the structure is shown which, as in the previous case, has been reinforced by means of struts B1 and B2. This is done by rolling, which is also a technique for moving heavy loads known per se, for example of self-propelled carts type. The structure is lifted and moved to its final position by means of self-propelled CA trolleys, here 4, arranged side by side inside the gantry between the legs. They wind couples, in particular
s hydrauliquement, de telle sorte qu'ils vent amenes a reagir de fa,con unique. s hydraulically, so that they can react in a unique way.
Ces chariots vent equipes de roues multidirectionnelles et de verins. Le nombre d'essieux et leur repartition vent determines en fonction de la charge a transporter. Cette solution permet de limiter ainsi les pressions sur le sol et d' absorber les defauts de nivellement du terrain dans une certaine o mesure. Le cas echeant, on interpose des plaques de repartition de charge entre les roues et le terrain. Comme on le volt sur la figure, la structure est en appui sur un ensemble de tours d'etaiement T qui reposent sur les These wind carts equipped with multidirectional wheels and cylinders. The number of axles and their wind distribution determined according to the load to be transported. This solution thus makes it possible to limit the pressures on the ground and to absorb the leveling faults of the ground to a certain extent. If necessary, load distribution plates are interposed between the wheels and the terrain. As shown in the figure, the structure is supported by a set of shoring towers T which rest on the
chariots CA.CA carts.
