Abstract
Description
L'invention concerne la pose de voussoirs au moyen d'une poutre haubannée, notamment pour construire un pont.The invention relates to the installation of segments using a guyed beam, in particular for building a bridge.
Le mot "voussoir" doit être considéré ici comme désignant une tranche d'un ouvrage, par exemple du tablier de pont, destiné à être assemblée avec d'autres tranches similaires pour constituer l'ouvrage de proche en proche.The word "voussoir" should be considered here as designating a section of a structure, for example of the bridge deck, intended to be assembled with other similar sections to constitute the structure gradually.
L'invention sera décrite à propos du prolongement du tablier d'un pont.The invention will be described in connection with the extension of the bridge deck.
On connaît un procédé dit de "pose en encorbellement" pour mettre en place des voussoirs dans le prolongement d'une portion de tablier de pont au moyen d'une poutre haubannée reposant sur un appui arrière et sur un appui avant articulé.There is known a process known as "cantilever laying" for setting up segments in the extension of a portion of bridge deck by means of a guyed beam resting on a rear support and on an articulated front support.
Les procédés connus de ce type ne permettent généralement de ne mettre en place qu'un ou deux voussoirs à la fois car la mise en place de plusieurs voussoirs simultanément par les procédés connus nécessiterait que le transfert de la charge des voussoirs de la poutre au tablier soit progressif, ce que les procédés connus ne permettent pas.Known methods of this type generally only allow one or two segments to be put in place at the same time since the placement of several segments simultaneously by the known methods would require that the transfer of the load of the segments from the beam to the deck is progressive, which the known methods do not allow.
Un but de la présente invention est de perfectionner un procédé de ce type en sorte qu'il soit possible de faire passer progressivement la charge de plusieurs voussoirs de la poutre au tablier dans le même temps que la mise en oeuvre de la précontrainte correspondante.An object of the present invention is to improve a process of this type so that it is possible to gradually pass the load of several segments from the beam to the deck at the same time as the implementation of the corresponding prestress.
On y parvient selon la pr sente invention, par un procédé qui comprend une première phase durant laquelle on suspend les voussoirs en porte à faux à ladite poutre et on maintient sensiblement immobile la partie de la poutre qui est en arrière de l'appui avant et une deuxième phase durant laquelle on solidarise les voussoirs à ladite portion en réalisant une précontrainte dans les voussoirs et ladite portion, et on transfère progressivement le poids des voussoirs à ladite portion sensiblement simultanément à la mise en oeuvre de la précontrainte, ceci étant obtenu en autorisant progressivement un basculement de ladite partie arrière de la poutre autour de l'appui avant pendant ladite deuxième phase.This is achieved according to the present invention, by a process which comprises a first phase during which the segments are suspended cantilevered to said beam and the part of the beam which is behind the front support is kept substantially immobile. a second phase during which we soli darise the segments to said portion by carrying out a prestressing in the segments and said portion, and the weight of the segments to said portion is gradually transferred substantially simultaneously with the implementation of the prestressing, this being obtained by gradually authorizing a tilting of said part rear of the beam around the front support during said second phase.
De façon typique, la poutre entre son état précédant le chargement avec les voussoirs et l'état final après transfert complet du chargement au tablier n'a subit qu'un basculement d'ensemble autour de l'appui avant.Typically, the beam between its state before loading with the segments and the final state after complete transfer of the load to the deck has only undergone an overall tilting around the front support.

On suppose (Figure 1) que l'on doit poser des voussoirs 1 dans le prolongement d'une portion de tablier 2, déjà construite, pour réaliser une travée d'un pont. La portion 2 repose, par exemple, sur des appuis représentés par des piles 3 et 4.It is assumed (Figure 1) that we must install
On met en place, de façon en soi connue, une poutre haubannée 5 en sorte que cette poutre repose sur deux appuis, à savoir un appui avant 6 et un appui arrière 7. Ces deux appuis sont généralement des appuis sur le tablier mais ils peuvent en variante être des appuis indépendants du tablier, par exemple des appuis sur les piles ou sur des massifs naturels.Is set up, in known manner, a guyed beam 5 so that this beam rests on two supports, namely a

Il n'est pas nécessaire de décrire avec plus de détails ces dispositions qui sont bien connues des hommes de métier et que l'on a seulement rappelé ci-dessus pour la clarté de l'exposé.It is not necessary to describe in more detail these arrangements which are well known to those skilled in the art and which have only been recalled above for the sake of clarity.
Les Figures 2 à 5 sont différentes vues longitudinales d'une réalisation conforme à l'invention. La Figure 2 montre la région de l'appui arrière 7 ; les Figures 3 et 4 montrent respectivement la région de l'appui articulé avant et la région de l'extrémité avant de la poutre ; la Figure 5 est une vue d'une région de la poutre, intermédiaire entre celle de la Figure 3 et celle de la Figure 4, où se trouve suspendu un voussoir 1.Figures 2 to 5 are different longitudinal views of an embodiment according to the invention. Figure 2 shows the region of the
Sur les Figures 2 à 8, les parties de la poutre 5 qui sont respectivement en arrière et en avant de l'appui articulé 6 sont désignées respectivement par les références 5a et 5b.In Figures 2 to 8, the parts of the beam 5 which are respectively behind and in front of the articulated
Selon l'invention, l'appui arrière 7 est conçu pour pouvoir maintenir immobile, pendant le chargement de la poutre avec les voussoirs, la partie de la poutre qui est en arrière de l'appui articulé 6 et pour pouvoir autoriser un basculement de cette partie arrière, au fur et à mesure que les voussoirs 1 sont solidarisés par la précontrainte et constituent une poutre devenant elle-même partie du tablier ce qui assure le transfert de poids individuel des voussoirs à la nouvelle structure constituée par le tablier 2 et son prolongement.According to the invention, the
Dans une réalisation préférée, cet appui arrière 7 se fait par l'intermédiaire d'un vérin ou d'un ensemble de vérinsqui agissent pour commander un basculement contrôlé de la partie arrière du tablier pendant la phase de transfert du poids des voussoirs au tablier.In a preferred embodiment, this
Sur la Figure 2, on a représenté pour l'exemple une réalisation de l'appui arrière en supposant que, dans ce cas, l'appui comporte un seul vérin 8.In FIG. 2, an embodiment of the rear support is shown for the example, assuming that, in this case, the support comprises a
Le cylindre du vérin 8 est porté par un support 9, suspendu a la partie arrière 5a de la poutre par des suspentes 10, et la tige du vérin 8 est en pression contre une platine 11 reliée par des câbles 12 à un massif 13 situé au droite de la pile 3.The cylinder of the
La partie arrière des haubans 14 de la poutre est visible sur la Figure 2 ; la partie moyenne et le mât 15 apparaissent partiellement sur la Figure 3 tandis que la partie avant des haubans apparaît sur les Figures 4 et 5.The rear part of the
On suppose pour simplifier qu'avant chargement avec les voussoirs la poutre est horizontale, comme indiqué sur la Figure 6(A).It is assumed for simplicity that before loading with the segments the beam is horizontal, as shown in Figure 6 (A).
De façon en soi connue, on suspend les voussoirs à poser à des chariots montés à coulisse sur la poutre et on déplace les chariots le long de la poutre jusqu'à ce que les voussoirs soient à la position qui leur a été assignée dans le prolongement du tablier. La Figure 5 montre un voussoir 1 en cours de déplacement. Il est suspendu par des câbles 16 à des chariots 17. Eventuellement, comme dans le cas illustré, le voussoir devra être pivoté de 90° pour être amené en position de service (comme représenté sur la Figure 3).In a manner known per se, the segments to be placed are suspended from carriages mounted to slide on the beam and the carriages are moved along the beam until the segments are in the position assigned to them in the extension. of the apron. Figure 5 shows a
Une pluralité de voussoirs sont ainsi acheminés la partie 5b de la poutre où ils se trouvent disposés à la suite les uns des autres.A plurality of segments are thus routed
Sous l'effet de la prise en charge des voussoirs la partie avant de la poutre prend une déformation verticale importante, nulle au niveau de l'articulation 6 maximale au bout de l'extrémité en porte-à-faux de la poutre. L'appui arrière 7, immobilisé, maintient immobile la partie arrière 5a de la poutre. Cela est schématisé sur la Figure 6(B).Under the effect of the support of the segments the front part of the beam takes a significant vertical deformation, zero at the level of the
On notera que la déformation de la poutre est occasionnée par la mise en traction des haubans donc par leur allongement. Dans le fonctionnement de la poutre, l'appui arrière est en traction : il équilibre le renversement de la poutre occasionné par les voussoirs en porte-à-faux. On dimensionne le haubannage de telle façon que sous l'action du chargement apporté par les voussoirs la déformation verticale de la partie avant de la poutre soit sensiblement linéaire. Il faut noter enfin que les déformations verticales de la partie avant de la poutre sont très importantes vis-à-vis des déformations d'une part, des câbles reliant la poutre aux voussoirs et, d'autre part, du tablier lui-même sous l'action conjuguée de son poids propre et de la précontrainte de solidarisation.It will be noted that the deformation of the beam is caused by the tensioning of the shrouds therefore by their elongation. In the operation of the beam, the rear support is in traction: it balances the overturning of the beam caused by the cantilever segments. The shrouding is dimensioned so that under the action of the loading provided by the segments the vertical deformation of the front part of the beam is substantially linear. Finally, it should be noted that the vertical deformations of the front part of the beam are very significant vis-à-vis the deformations on the one hand, of the cables connecting the beam to the segments and, on the other hand, of the deck itself under the combined action of its own weight and the prestressing of solidarity.
Après réglage en nivellement des voussoirs et un léger serrage de présolidarisation, on procède à la solidarisation par précontrainte des voussoirs au tablier déjà construit.After adjustment in leveling of the segments and a slight tightening of pre-consolidation, we proceed to the joining by prestressing of the segments to the already constructed deck.
Sur la Figure 4, on a schématisé l'ensemble des vérins de précontrainte par un vérin 18 qui tire un câble de précontrainte 19 à travers les voussoirs représentés en traits mixtes.In Figure 4, there is shown schematically all of the prestressing cylinders by a
Selon l'invention, on crée un asservissement (automatique ou manuel) entre le(s) vérin(s) de l'appui arrière de la poutre et le(s) vérin(s) de précontrainte. Cet asservissement est schématisé sur la Figure 6(C) par une ligne 20 en traits interrompus.According to the invention, a servo-control (automatic or manual) is created between the cylinder (s) of the rear support of the beam and the prestressing cylinder (s). This control is shown diagrammatically in FIG. 6 (C) by a line 20 in broken lines.
Avant mise en tension des câbles de précontrainte, le vérin de l'appui arrière est chargé, celui de mise en tension des câbles de précontrainte n'est pas chargé. Du fait de l'asservissement entre ces deux vérins, au fur et à mesure de la mise en tension des câbles, le vérin de l'appui arrière de la poutre se dégonfle.Cette opération permet ainsi automatiquement le transport _de charge du poids propre du tablier dans le tablier lui-même au fur et à mesure de la mise en tension des câbles de précontrainte. On assiste à une détension progressive du haubannage ; l'avant 5b de poutre reste pratiquement immobile, tandis que son arrière 5a bascule vers le haut jusqu'à s'aligner sensiblement avec la partie avant de la poutre. Cette phase finale est représentée sur la Figures 6(C). La poutre de pose a retrouvé l'état de déformation de la Figure 6(A), à une rotation d'ensemble près.Before tensioning the prestressing cables, the jack of the rear support is loaded, that of tensioning the prestressing cables is not loaded. Due to the enslavement between these two cylinders, as the cables are tensioned, the cylinder of the rear support of the beam deflates. This operation thus automatically allows the load transport of the dead weight of the apron in the apron itself as the prestressing cables are tensioned. We are witnessing a gradual relaxation of the shrouding; the front 5b of the beam remains practically immobile, while its rear 5a rocks upwards until it is substantially aligned with the front part of the beam. This final phase is shown in Figures 6 (C). The laying beam has recovered the deformation state of Figure 6 (A), to the nearest whole rotation.
La poutre n'est pas nécessairement horizontale au départ et la Figure 7 est relative à un exemple dans lequel la poutre, au départ, est inclinée vers le haut. On a supposé que sa rotation d'ensemble lui fait prendre une position finale où elle est sensiblement horizontale.The beam is not necessarily horizontal at the start and Figure 7 relates to an example in which the beam, at the start, is inclined upwards. We assumed that its overall rotation makes it take a final position where it is substantially horizontal.
Si cela apparaît utile, pendant la phase de chargement de la poutre et dans le but de la soulager on limite le basculement de la partie en porte-à-faux au moyen d'un appui et on supprime cet appui à un instant donné de la deuxième phase durant laquelle on réalise la précontrainte. Par exemple, si l'on désire augmenter les performances de la poutre, par exemple en posant un ou des voussoirs supplémentaires dont les poids ajoutés à ceux des voussoirs déjà prévus conduiraient à une charge inadmissible pour la poutre, on équipe la poutre (Figure 8) d'une béquille 21à son extrémité avant et l'on met la béquille en appui sur le pont ou sur un appui provisoire 22. On amène le ou les voussoirs supplémentaires. La béquille se met en charge et soulage la poutre de pose. On procède ensuite à la mise en précontrainte de l'ensemble des voussoirs telle que décrit plus haut. A un moment déterminé de la mise en tension, on libère la béquille avant.If this appears useful, during the loading phase of the beam and in order to relieve it, the tilting of the cantilevered part is limited by means of a support and this support is removed at a given time from the second phase during which the prestressing is carried out. For example, if one wishes to increase the performance of the beam, for example by laying one or more additional segments whose weights added to those of the segments already planned would lead to an unacceptable load for the beam, we equip the beam (Figure 8 ) a
