DOMAINE DE L'INVENTION FIELD OF THE INVENTION
L’invention concerne de manière générale le forage d’un tunnel, et plus particulièrement l’évacuation des déblais gérés par un tel forage, notamment dans le cas d’un tunnelier à pression de boue. The invention relates generally to the boring of a tunnel, and more particularly to the removal of the cuttings managed by such a borehole, in particular in the case of a mud pressure tunnel boring machine.
ETAT DE LA TECHNIQUE STATE OF THE ART
On connaît des machines de creusement de tunnels, appelées tunneliers, qui comportent une structure mobile de grandes dimensions consistant en une grande usine mobile à l’avant de laquelle est disposé un bouclier ayant une section compatible avec la future section en adéquation avec la forme définitive du tunnel (tunnel de section circulaire, bilobé, etc.) There are known tunneling machines, called tunnel boring machines, which comprise a large mobile structure consisting of a large mobile plant at the front of which is placed a shield having a section compatible with the future section in line with the final shape. tunnel (circular section tunnel, bilobed, etc.)
La partie antérieure du bouclier qui vient en contact avec le front de taille pour réaliser la découpe de la formation géologique traversée par le tunnel comporte une roue de coupe supportant des outils de travail qui est entraînée en rotation à une vitesse variable et qui est couplée à une poussée que l’on adapte à la nature du terrain à creuser. The anterior part of the shield which comes into contact with the working face to cut the geological formation crossed by the tunnel has a cutting wheel supporting working tools which is rotated at a variable speed and which is coupled to a thrust that we adapt to the nature of the ground to be excavated.
La roue de coupe travaille en pression. Elle est montée à l'avant d'une chambre, dite chambre d'abattage, selon le sens de déplacement du tunnelier. La partie arrière du tunnelier, dénommée train suiveur, comprend, outre différents appareils permettant la circulation des fluides entre le tunnel et la surface (sortie du tunnel), l'ensemble des dispositifs de pilotage, de sécurité et de mise en place de voussoirs constitutifs du tunnel. De la boue (« slurry » en anglais) est injectée sous pression à l'avant du front de taille à partir de la chambre d'abattage. Cette boue a pour fonction de lubrifier la roue de coupe, d'assurer la stabilité des parois de l'excavation et, lors de son trajet de retour jusqu'à la surface, de fluidifier le transport des matériaux (le marin) issus de l'excavation. The cutting wheel works under pressure. It is mounted at the front of a chamber, called a slaughter chamber, according to the direction of movement of the tunnel boring machine. The rear part of the tunnel boring machine, called the following train, includes, in addition to various devices allowing the circulation of fluids between the tunnel and the surface (exit of the tunnel), all the control and safety devices and the installation of constituent segments. of the tunnel. Mud ("slurry" in English) is injected under pressure at the front of the working face from the slaughter chamber. The function of this mud is to lubricate the cutting wheel, to ensure the stability of the walls of the excavation and, during its return journey to the surface, to facilitate the transport of materials (the sailor) from the excavation. 'excavation.
De manière connue en soi, le marin est transporté de la roue de coupe à la surface par une ou plusieurs conduites de marinage. Chaque conduite de marinage comprend une canalisation de sortie, raccordée à la tête de coupe du tunnelier, une section aval, fixe et rigide, raccordée à une station de traitement des boues et un tuyau flexible raccordant la canalisation de sortie et la section aval. Pour permettre l’avancement du tunnelier, le tuyau flexible est plié de sorte à créer un jeu entre la canalisation et la section aval, puis se déplie progressivement au cours de l’avancement du tunnelier jusqu’à être sensiblement allongé. Une section supplémentaire de conduite, rigide, est ensuite rapportée et insérée entre le tuyau flexible et la section aval. Le tuyau flexible est alors replié et le tunnelier peut poursuivre son avancée. In a manner known per se, the sailor is transported from the cutting wheel to the surface by one or more marinating pipes. Each marinating pipe comprises an outlet pipe, connected to the cutting head of the tunnel boring machine, a downstream section, fixed and rigid, connected to a sludge treatment station and a pipe flexible connecting the outlet pipe and the downstream section. To allow the advancement of the tunnel boring machine, the flexible pipe is bent so as to create a clearance between the pipe and the downstream section, then unfolds progressively during the advancement of the tunnel boring machine until it is significantly extended. An additional section of rigid pipe is then attached and inserted between the flexible pipe and the downstream section. The flexible pipe is then folded back and the tunnel boring machine can continue to advance.
Toutefois, le montage de la section supplémentaire est long et nécessite une manutention lourde. En effet, la section supplémentaire doit être suspendue et manipulée à l’aide de palans à chaîne par les opérateurs. Une fois la section supplémentaire à proximité de la section aval, un ou plusieurs opérateurs doivent l’aligner avec la section aval avant de la raccorder en position, en tenant simultanément un collier de serrage, des boulons et une clé à choc. L’opération de raccordement nécessite en outre que les opérateurs supportent et maintiennent en position les deux sections de conduite en vis-à-vis pendant le serrage du collier et la fixation des boulons, ce qui est difficile compte-tenu de l’encombrement des sections de conduite et leur poids. Par ailleurs, cette opération est délicate puisqu’il est nécessaire que tous ces éléments soient assemblés précisément pour garantir le montage du collier. En cas d’échec, ces différentes étapes doivent être réitérées. However, the assembly of the additional section is long and requires heavy handling. This is because the additional section must be suspended and manipulated with chain hoists by the operators. Once the additional section is near the downstream section, one or more operators should align it with the downstream section before connecting it in position, simultaneously holding a hose clamp, bolts and an impact wrench. The connection operation further requires that the operators support and hold in position the two opposite pipe sections while tightening the clamp and fixing the bolts, which is difficult given the bulk of the pipes. pipe sections and their weight. Moreover, this operation is delicate since it is necessary that all these elements be assembled precisely to ensure the mounting of the collar. If this fails, these different steps must be repeated.

DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION
De manière classique, un tunnelier comprend, en partie avant, un bouclier ayant une section sensiblement circulaire dont le diamètre correspond au diamètre du tunnel dont on réalise le creusement. Le bouclier loge une roue de coupe qui vient en contact avec le front de taille pour creuser le tunnel et qui est mobile en rotation autour d’un axe. Conventionally, a tunnel boring machine comprises, in the front part, a shield having a substantially circular section, the diameter of which corresponds to the diameter of the tunnel which is being excavated. The shield houses a cutting wheel which comes into contact with the working face to dig the tunnel and which is movable in rotation about an axis.
Le tunnelier comporte en outre un train suiveur s’étendant derrière le bouclier et qui avance en même temps que la roue de coupe lors du creusement du tunnel. The tunnel boring machine also has a follower train extending behind the shield and which moves along with the cutting wheel as the tunnel is excavated.
De manière connue en soi, la roue de coupe est montée à l'avant d'une chambre d’abattage. De la boue est injectée sous pression à l'avant du front d'attaque à partir de la chambre d'abattage, et le marin est transporté de la roue de coupe à la surface par une ou plusieurs conduites de marinage. In a manner known per se, the cutting wheel is mounted in front of a harvesting chamber. Mud is injected under pressure forward of the leading front from the slaughter chamber, and the sailor is transported from the cutting wheel to the surface through one or more pickling lines.
Chaque conduite de marinage 1 comprend une canalisation de sortie 2, raccordée à la tête de coupe du tunnelier (au niveau de la chambre d’abattage), une section de conduite aval 3 raccordée à une station de traitement des boues et un tuyau flexible 4 raccordant la canalisation de sortie et la section aval. Each pickling pipe 1 comprises an outlet pipe 2, connected to the cutting head of the tunnel boring machine (at the level of the felling chamber), a downstream pipe section 3 connected to a sludge treatment station and a flexible pipe 4 connecting the outlet pipe and the downstream section.
Les figures 1 a à 1 d illustrent le montage d’une section supplémentaire 5 d’une conduite de marinage 1 lors de l’avancée d’un tunnelier. Figures 1 a to 1 d illustrate the assembly of an additional section 5 of a marinating pipe 1 during the advance of a tunnel boring machine.
Sur la figure 1 a, le tuyau flexible 4 est tendu entre la canalisation de sortie 2 et la section aval 3 de la conduite de marinage 1 . Il n’y a donc plus de jeu suffisant pour permettre au tunnelier de poursuivre son avancée, la section aval 3 étant fixe. In Figure 1a, the flexible pipe 4 is stretched between the outlet pipe 2 and the downstream section 3 of the pickling pipe 1. There is therefore no longer sufficient clearance to allow the tunnel boring machine to continue its advance, the downstream section 3 being fixed.
Le tuyau flexible 4 est alors séparé de la section aval 3 puis plié de sorte à recréer un jeu (figure 1 b). The flexible pipe 4 is then separated from the downstream section 3 and then bent so as to recreate a clearance (FIG. 1 b).
Une section supplémentaire 5 est ensuite rapportée entre le tuyau flexible 4 et la section aval 3 de la conduite (figure 1 c). An additional section 5 is then attached between the flexible pipe 4 and the downstream section 3 of the pipe (FIG. 1 c).
La section de conduite aval 3 et la section supplémentaire 5 sont rigides. The downstream pipe section 3 and the additional section 5 are rigid.
Enfin, la section supplémentaire 5 est raccordée au tuyau flexible 4 et à la section aval 3, de sorte à remettre la chambre d’abattage et la station de traitement des boues en communication fluidique. Le tunnelier peut ensuite reprendre le creusement et avancer. Afin de simplifier le montage de la section supplémentaire 5 sur la section aval 3 de la conduite de marinage 1 , l’invention propose un outillage 6 comprenant : Finally, the additional section 5 is connected to the flexible pipe 4 and to the downstream section 3, so as to put the slaughter chamber and the sludge treatment station back in fluid communication. The TBM can then resume digging and move forward. In order to simplify the mounting of the additional section 5 on the downstream section 3 of the pickling pipe 1, the invention provides a tool 6 comprising:
- un premier support 10, configuré pour recevoir la section aval 3 de la conduite de marinage 1 , - a first support 10, configured to receive the downstream section 3 of the pickling pipe 1,
- un deuxième support 20, fixé solidairement au premier support 10 et configuré pour recevoir la section supplémentaire 5 et - a second support 20, fixedly fixed to the first support 10 and configured to receive the additional section 5 and
- un système de positionnement 30 de la section supplémentaire 5 par rapport à la section aval 3 de la conduite de marinage 1 en vue d’aligner ladite section supplémentaire 5 par rapport à la section aval 3. - A positioning system 30 of the additional section 5 relative to the downstream section 3 of the pickling pipe 1 in order to align said additional section 5 with respect to the downstream section 3.
Un tel outillage 6 permet ainsi de supprimer les manipulations de la section supplémentaire 5 avec le palan à chaîne, puisque la section supplémentaire 5 est amenée sur le deuxième support 20 puis alignée grâce au système de positionnement 30. En simplifiant l’alignement des sections, leur positionnement relatif peut également être amélioré lors de leur raccordement. Such a tool 6 thus makes it possible to eliminate the handling of the additional section 5 with the chain hoist, since the additional section 5 is brought onto the second support 20 and then aligned thanks to the positioning system 30. By simplifying the alignment of the sections, their relative positioning can also be improved when they are connected.
Dans ce qui suit, on désignera par « axe longitudinal X » un axe passant par le premier support 10 qui est sensiblement parallèle à l’axe de révolution de la section aval 3 de la conduite, par « axe vertical Z » un axe comprise dans le plan normal à l’axe longitudinal X et qui est sensiblement normal au sol sur lequel est posé le premier support 10 de l’outillage 6, et par « axe transversal Y » un axe perpendiculaire à l’axe vertical Z et à l’axe longitudinal X. In what follows, “longitudinal axis X” will denote an axis passing through the first support 10 which is substantially parallel to the axis of revolution of the downstream section 3 of the pipe, by “vertical axis Z” an axis included in the plane normal to the longitudinal axis X and which is substantially normal to the ground on which the first support 10 of the tool 6 is placed, and by "transverse axis Y" an axis perpendicular to the vertical axis Z and to the longitudinal axis X.
Le premier support 10 peut notamment comprendre une embase 1 1 configurée pour recevoir la section aval 3 et une pince 12 configurée pour bloquer en translation et en rotation la section aval 3 par rapport au premier support 10. La pince 12 peut par exemple être montée mobile en rotation autour d’un axe sensiblement parallèle à l’axe de rotation. The first support 10 may in particular comprise a base 11 configured to receive the downstream section 3 and a clamp 12 configured to block the downstream section 3 in translation and in rotation relative to the first support 10. The clamp 12 can for example be mounted mobile. rotating about an axis substantially parallel to the axis of rotation.
Dans l’exemple de réalisation illustré sur les figures, le premier support 10 comprend un socle 13 sur lequel est fixée l’embase 1 1 configurée pour recevoir la section aval 3 et un bras 14 s’étendant depuis le socle 13 suivant une direction sensiblement parallèle à l’axe vertical Z, le long de la section aval 3. La pince 12 est montée à rotation sur le bras 14 et sur l’embase 1 1 de sorte à serrer la section aval 3 contre l’embase 1 1 et à la maintenir ainsi en position par rapport au premier support 10. Le cas échéant, le bras 14 peut lui-même être monté mobile à rotation par rapport au socle 13, soit via une liaison pivot dont l’axe est parallèle à l’axe longitudinale X, soit via une liaison rotule. La pince 12 peut notamment être actionnée par un bloc hydraulique 15. In the embodiment illustrated in the figures, the first support 10 comprises a base 13 on which is fixed the base 1 1 configured to receive the downstream section 3 and an arm 14 extending from the base 13 in a substantially direction. parallel to the vertical axis Z, along the downstream section 3. The clamp 12 is rotatably mounted on the arm 14 and on the base 1 1 so as to clamp the downstream section 3 against the base 1 1 and to thus keep it in position relative to the first support 10. Where appropriate, the arm 14 can itself be mounted so as to be able to rotate with respect to the base 13, either via a pivot connection whose axis is parallel to the longitudinal axis X, or via a ball joint. The clamp 12 can in particular be actuated by a hydraulic unit 15.
Le deuxième support 20 quant à lui comprend une embase 21 configurée pour recevoir la section supplémentaire 5. L’embase 21 est solidaire du premier support 10 de sorte à faciliter l’alignement de la section supplémentaire 5 avec la section aval 3, le premier support 10 servant de référence pour le positionnement du deuxième support 20. Pour cela, dans une forme de réalisation, l’embase 21 du deuxième support 20 peut par exemple être montée sur le socle 13 du premier support 10. En variante, l’embase 21 du deuxième support 20 peut être montée sur un socle distinct qui est rapporté et fixé sur le socle 13 du premier support 10. The second support 20 for its part comprises a base 21 configured to receive the additional section 5. The base 21 is integral with the first support 10 so as to facilitate the alignment of the additional section 5 with the downstream section 3, the first support. 10 serving as a reference for the positioning of the second support 20. For this, in one embodiment, the base 21 of the second support 20 can for example be mounted on the base 13 of the first support 10. As a variant, the base 21 of the second support 20 can be mounted on a separate base which is attached and fixed to the base 13 of the first support 10.
Dans l’exemple de réalisation illustré sur les figures, le socle 13 du deuxième support 20 est commun avec celui du premier support 10. In the exemplary embodiment illustrated in the figures, the base 13 of the second support 20 is common with that of the first support 10.
Dans une forme de réalisation, le système de positionnement 30 comprend des moyens de centrage de la section aval 3 de la conduite de marinage 1 par rapport au premier support 10. Avantageusement, les moyens de centrage permettent de définir une position de référence pour la section aval 3 suivant l’axe vertical Z et l’axe transversal Y, simplifiant ensuite les opérations d’alignement de la section supplémentaire 5 par rapport à la section aval 3. In one embodiment, the positioning system 30 comprises means for centering the downstream section 3 of the pickling pipe 1 with respect to the first support 10. Advantageously, the centering means make it possible to define a reference position for the section. downstream 3 along the vertical axis Z and the transverse axis Y, then simplifying the alignment operations of the additional section 5 with respect to the downstream section 3.
De préférence, le système de positionnement 30 comprend à la fois des moyens de centrage de la section aval 3 de la conduite de marinage 1 et des moyens de centrage de la section supplémentaire 5 pour faciliter leur alignement et la fixation de la section supplémentaire 5 sur la section aval 3. Preferably, the positioning system 30 comprises both means for centering the downstream section 3 of the pickling pipe 1 and means for centering the additional section 5 to facilitate their alignment and the fixing of the additional section 5 on the downstream section 3.
Par exemple, la surface d’appui 31 , 32 de chaque embase 1 1 , 21 qui reçoit la section supplémentaire 5 (respectivement, la section aval 3) peut assurer la fonction de centrage de la section supplémentaire 5 (respectivement, de la section aval 3). Pour cela, la surface d’appui 31 , 32 peut être configurée pour venir en contact avec la section supplémentaire 5 (respectivement, la section aval 3) en deux zones distinctes, de préférence symétriques par rapport à un plan vertical parallèle à l’axe longitudinal X. Typiquement, chaque surface d’appui 31 , 32 peut comprendre deux pans inclinés (voir figures 3 et 4) de sorte à former un V. Les pans inclinés de la surface d’appui 31 , 32 peuvent se rejoindre le long d’une ligne ou être séparés par une gorge. Une telle surface d’appui 31 , 32 permet ainsi de placer la section aval 3 et la section supplémentaire 5 dans des positions de référence suivant les axes vertical et transversal. For example, the bearing surface 31, 32 of each base 1 1, 21 which receives the additional section 5 (respectively, the downstream section 3) can provide the function of centering the additional section 5 (respectively, the downstream section 3). For this, the bearing surface 31, 32 can be configured to come into contact with the additional section 5 (respectively, the downstream section 3) in two distinct zones, preferably symmetrical with respect to a vertical plane parallel to the axis. longitudinal X. Typically, each bearing surface 31, 32 may comprise two inclined sides (see Figures 3 and 4) so as to form a V. The inclined sides of the bearing surface 31, 32 can meet along a line or be separated by a groove. Such a bearing surface 31, 32 thus makes it possible to place the downstream section 3 and the additional section 5 in reference positions along the vertical and transverse axes.
Une surface d’appui 31 , 32 en forme de V permet en outre de centrer les sections de conduite 3, 5 indépendamment de leur diamètre. A V-shaped bearing surface 31, 32 further enables the pipe sections 3, 5 to be centered regardless of their diameter.
Le système de positionnement 30 est configuré pour déplacer la section supplémentaire 5 par rapport à la section aval 3 suivant l’axe longitudinal X en vue de placer la section supplémentaire 5 à une distance adaptée de la section aval 3 pour permettre leur fixation mutuelle. The positioning system 30 is configured to move the additional section 5 relative to the downstream section 3 along the longitudinal axis X in order to place the additional section 5 at a suitable distance from the downstream section 3 to allow their mutual attachment.
Pour cela, dans une forme de réalisation, le système de positionnement 30 comprend un actionneur configuré pour translater la section supplémentaire 5 par rapport à la première section de conduite. Par exemple, l’actionneur peut comprendre une crémaillère 33 qui est montée sur l’embase 21 de sorte à s’étendre parallèlement à l’axe longitudinal X, et une roue dentée 34 associée, montée mobile en rotation autour d’un axe transversal Y sur le socle 13 du deuxième support 20 et pouvant être actionnée par exemple par une manivelle 35 ou mise en rotation par un moteur. La rotation de la roue dentée 34 a alors pour effet de déplacer la crémaillère 33 et donc l’embase 21 du deuxième support 20 (qui supporte la section supplémentaire 5) le long de l’axe longitudinal X afin de rapprocher ou d’éloigner ladite embase 21 du premier support 10 (et donc la section supplémentaire 5 de la section aval 3). De manière équivalente, on comprendra bien sûr que la roue dentée 34 pourrait être montée sur l’embase 21 du deuxième support 20 tandis que la crémaillère 33 est montée fixe sur le socle 13. For this, in one embodiment, the positioning system 30 comprises an actuator configured to translate the additional section 5 relative to the first pipe section. For example, the actuator may comprise a rack 33 which is mounted on the base 21 so as to extend parallel to the longitudinal axis X, and an associated toothed wheel 34, mounted to be movable in rotation about a transverse axis. Y on the base 13 of the second support 20 and can be actuated for example by a crank 35 or rotated by a motor. The rotation of the toothed wheel 34 then has the effect of moving the rack 33 and therefore the base 21 of the second support 20 (which supports the additional section 5) along the longitudinal axis X in order to bring said closer or further away. base 21 of the first support 10 (and therefore the additional section 5 of the downstream section 3). Equivalently, it will of course be understood that the toothed wheel 34 could be mounted on the base 21 of the second support 20 while the rack 33 is fixedly mounted on the base 13.
En variante, l’actionneur comprend un chariot roulant monté fixement sur l’embase 21 et configuré pour coulisser sur le sol ainsi qu’un vérin de translation configuré pour déplacer le chariot roulant par rapport au sol afin de translater la section supplémentaire 5 par rapport à la première section de conduite. As a variant, the actuator comprises a rolling cart fixedly mounted on the base 21 and configured to slide on the ground as well as a translation cylinder configured to move the rolling cart relative to the ground in order to translate the additional section 5 with respect to to the first driving section.
L’outillage 6 permet ainsi de faciliter grandement le positionnement de la section aval 3 de la conduite de marinage 1 par rapport à la section supplémentaire 5. The tool 6 thus makes it possible to greatly facilitate the positioning of the downstream section 3 of the pickling line 1 relative to the additional section 5.
L’outillage 6 comprend en outre un réceptacle 22 configuré pour recevoir une portion inférieure d’un collier 7 de serrage pour la fixation de la section supplémentaire 5 sur la section aval 3. Le réceptacle 22 peut notamment être mobile en translation entre une position escamotée, dans laquelle la portion inférieure du collier 7 s’étend à distance de la section supplémentaire 5 de sorte à permettre sa mise en place sur l’embase 21 et son positionnement par rapport à la section aval 3, et une position de verrouillage dans laquelle la portion inférieure du collier 7 est appliquée contre la section supplémentaire 5 et la section aval 3 de sorte à permettre leur fixation mutuelle. Tooling 6 further comprises a receptacle 22 configured to receive a lower portion of a clamp 7 for securing the additional section. 5 on the downstream section 3. The receptacle 22 can in particular be movable in translation between a retracted position, in which the lower portion of the collar 7 extends at a distance from the additional section 5 so as to allow its installation on the. base 21 and its positioning relative to the downstream section 3, and a locking position in which the lower portion of the collar 7 is applied against the additional section 5 and the downstream section 3 so as to allow their mutual fixing.
Par exemple, le réceptacle 22 peut être monté sur un vérin 23, fixé sur le socle 13 du deuxième support 20 et mobile entre la position escamotée et la position de verrouillage. Ici, le vérin 23 présente donc une direction de translation sensiblement parallèle à l’axe vertical Z. Le cas échéant, le système de positionnement comprend également un chariot sur lequel est monté le vérin 23. Ce chariot est alors actionné par un vérin de translation associé afin de le translater lors de la mise en position de la section supplémentaire 5. For example, the receptacle 22 can be mounted on a jack 23, fixed on the base 13 of the second support 20 and movable between the retracted position and the locking position. Here, the jack 23 therefore has a direction of translation substantially parallel to the vertical axis Z. Where appropriate, the positioning system also comprises a carriage on which the jack 23 is mounted. This carriage is then actuated by a translation jack. associated in order to translate it when positioning the additional section 5.
Ainsi, l’outillage 6 permet en plus de faciliter la mise en place du collier 7 de serrage. Thus, the tool 6 also makes it possible to facilitate the installation of the clamp 7.
Le procédé S de montage de la section supplémentaire 5 de la conduite de marinage 1 sur la section aval 3 peut alors être réalisé conformément aux étapes suivantes. The method S of mounting the additional section 5 of the pickling pipe 1 on the downstream section 3 can then be carried out in accordance with the following steps.
Au cours d’une première étape S1 , le tuyau flexible 4 est séparé de la section aval 3 de la conduite de marinage 1 et est replié de sorte à ménager un jeu entre la canalisation de sortie 2 et la conduite de marinage 1 . During a first step S1, the flexible pipe 4 is separated from the downstream section 3 of the pickling pipe 1 and is folded back so as to leave a clearance between the outlet pipe 2 and the pickling pipe 1.
Cette étape de séparation étant conventionnelle, elle ne sera pas davantage décrite ici. This separation step being conventional, it will not be further described here.
Au cours d’une deuxième étape S2, l’outillage 6 est placé à proximité de l’extrémité libre de la section aval 3 de sorte que l’axe longitudinal X du premier support 10 soit sensiblement parallèle à l’axe de révolution de la section aval 3. During a second step S2, the tool 6 is placed near the free end of the downstream section 3 so that the longitudinal axis X of the first support 10 is substantially parallel to the axis of revolution of the downstream section 3.
La section aval 3 est ensuite positionnée sur le premier support 10 dans une position de référence donnée afin de faciliter l’alignement et la fixation de la section supplémentaire 5 sur la section aval 3. Pour cela, la section aval 3 peut par exemple être centrée par rapport au premier support 10 grâce aux moyens de centrage, typiquement grâce à une surface d’appui 31 en forme de V de l’embase 1 1 . Une telle surface d’appui 31 permet ainsi d’imposer la position de la section aval 3 suivant l’axe vertical Z et l’axe transversal Y. The downstream section 3 is then positioned on the first support 10 in a given reference position in order to facilitate the alignment and fixing of the additional section 5 on the downstream section 3. For this, the downstream section 3 can for example be centered. relative to the first support 10 thanks to the centering means, typically thanks to a V-shaped bearing surface 31 of the base 1 January. Such a bearing surface 31 thus makes it possible to impose the position of the downstream section 3 along the vertical axis Z and the transverse axis Y.
Au cours d’une troisième étape S3, une portion inférieure d’un collier 7 de serrage est placée sur le réceptacle 22 du deuxième support 20. During a third step S3, a lower portion of a clamp 7 is placed on the receptacle 22 of the second support 20.
Le réceptacle 22 est alors en position escamotée. The receptacle 22 is then in the retracted position.
Au cours d’une quatrième étape S4, une section supplémentaire 5 est amenée et placée sur le deuxième support 20, par exemple à l’aide d’un palan à chaîne. La section supplémentaire 5 est de préférence centrée sur l’embase 21 , par exemple grâce à des moyens de centrage tels qu’une surface d’appui 32 en forme de V de l’embase 21 du deuxième support 20. En variante, lorsque le deuxième support 20 est dépourvu de moyens de centrage, la section supplémentaire 5 peut positionnée par le ou les opérateurs de sorte à être sensiblement alignée avec la section aval 3. During a fourth step S4, an additional section 5 is brought and placed on the second support 20, for example by means of a chain hoist. The additional section 5 is preferably centered on the base 21, for example by means of centering means such as a V-shaped bearing surface 32 of the base 21 of the second support 20. As a variant, when the second support 20 is devoid of centering means, the additional section 5 can be positioned by the operator (s) so as to be substantially aligned with the downstream section 3.
Au cours d’une cinquième étape S5, la section supplémentaire 5 est rapprochée ou éventuellement éloignée de la section aval 3. Par exemple, l’embase 21 est déplacée suivant l’axe longitudinal X par le système de positionnement 30 en faisant tourner la manivelle 35 de sorte à faire tourner la roue dentée 34 (ou, en variante, démarre le moteur qui met en rotation la roue dentée 34) qui déplace alors la crémaillère 33 et donc l’embase 21 du deuxième support 20 suivant l’axe longitudinal X. Alternativement, lorsque les moyens de positionnement comprennent un ou plusieurs chariots, les chariots sont déplacés suivant l’axe longitudinal X par le vérin de translation associé. During a fifth step S5, the additional section 5 is moved closer to or possibly moved away from the downstream section 3. For example, the base 21 is moved along the longitudinal axis X by the positioning system 30 by turning the crank. 35 so as to rotate the toothed wheel 34 (or, in a variant, starts the motor which rotates the toothed wheel 34) which then moves the rack 33 and therefore the base 21 of the second support 20 along the longitudinal axis X Alternatively, when the positioning means comprise one or more carriages, the carriages are moved along the longitudinal axis X by the associated translation cylinder.
L’embase 21 est alors déplacée jusqu’à ce que la section supplémentaire 5 soit suffisamment proche de la section aval 3 pour permettre sa fixation. The base 21 is then moved until the additional section 5 is close enough to the downstream section 3 to allow its attachment.
Au cours d’une sixième étape S6, le réceptacle 22 est placé en position de verrouillage, par exemple en actionnant le vérin 23, afin d’appliquer le demi-collier 7 sur la partie inférieure de la section supplémentaire 5 et de la section aval 3. Une portion supérieure de collier 7 complémentaire de la portion inférieure peut alors être rapportée sur leur partie supérieure et fixée par boulonnage sur la portion inférieure qui est appliquée et maintenue en position contre les sections de conduite. La section supplémentaire 5 est alors fixée à la section aval 3 de la conduite de marinage 1 par serrage des portions de collier 7. During a sixth step S6, the receptacle 22 is placed in the locking position, for example by actuating the jack 23, in order to apply the half-collar 7 on the lower part of the additional section 5 and of the downstream section 3. An upper portion of collar 7 complementary to the lower portion can then be attached to their upper part and fixed by bolting to the lower portion which is applied and held in position against the pipe sections. The section additional 5 is then fixed to the downstream section 3 of the pickling pipe 1 by tightening the collar portions 7.
Au cours d’une septième étape S7, l’outillage 6 peut être retiré. Pour cela, le réceptacle 22 est de préférence ramené en position escamotée puis le premier et le deuxième support 20 sont retirés. In a seventh step S7, the tool 6 can be removed. For this, the receptacle 22 is preferably brought back to the retracted position then the first and the second support 20 are withdrawn.
Au cours d’une huitième étape S8, la section supplémentaire 5 peut être raccordée au tuyau flexible 4. Cette étant conventionnelle elle ne sera pas davantage détaillée ici. During an eighth step S8, the additional section 5 can be connected to the flexible pipe 4. This being conventional, it will not be further detailed here.
Bien entendu, les étapes S3 et S6 sont optionnelles, les portions de collier 7 pouvant être placées manuellement par les opérateurs sur les sections de conduite. Of course, steps S3 and S6 are optional, the collar portions 7 being able to be placed manually by the operators on the pipe sections.
