Abstract

The invention relates to a device for connecting corrugated pipes together or for blocking an opening in such a pipe. The device comprises three corrugated shell elements 16, 17, 18, the extension of which in the axial direction is preferably twice one corrugation, and each of which forms a circular arc of approximately 180 DEG . These shell elements may be obtained by cutting out a section from the tube itself. They are placed offset by 120 DEG with respect to one another, by pressing them into the corrugations of the underlying tube or tubes and/or of the underlying shell element. Application to large or very large-diameter corrugated pipes.

Description

La présente invention est relative à un dispositif pour relier ensemble des tuyaux ondulés, en particulier de gros et très gros diamètre nominal, à l'aide de coquilles entourant la périphérie des tuyaux et pénétrant dans les ondulations des deux tuyaux. The present invention relates to a device for connecting together corrugated pipes, in particular of large and very large nominal diameter, using shells surrounding the periphery of the pipes and penetrating into the corrugations of the two pipes.

Il est usuel de prévoir des tuyaux de drainage en matière synthétique à paroi ondulée. Les ondulations en hélice ou en anneaux procurent au tuyau une haute résistance à lâ pression et une flexibilité convenable. It is usual to provide plastic drainage pipes with corrugated walls. The helical or ring corrugations provide the pipe with high pressure resistance and suitable flexibility.

Les extrémités des tuyaux placés bout-à-bout doivent être reliées l'une à l'autre à l'aide d'un accouplement adapté. Celui-ci est normalement constitué d'un manchon à embottement, c'est-à-dire un manchon formé de deux demi-coquilles, qui pénétrent dans les ondulations des extrémités des tuyaux et qui sont liées l'une à l'autre à leurs extrémités libres, par exemple à l'aide de vis, par vissage ou de façon analogue. Les tuyaux de drainage, ou les tubes profilés de diamètre inférieur, sont normalement fournis enroulés sur un touret, si bien que les liaisons entre tuyaux ne sont nécessaires qu'à des distances relativement importantes. Les tuyaux plus gros, dits collecteurs ne peuvent être produits et transportés que par longueurs plus faibles, par exemple 6 ou 8 mètres, et exigent par conséquent un nombre plus grand de manchons à embottement.The ends of the pipes placed end to end must be connected to each other using a suitable coupling. This normally consists of a flanged sleeve, that is to say a sleeve formed by two half-shells, which penetrate the undulations of the ends of the pipes and which are linked to each other. their free ends, for example using screws, screwing or the like. Drainage pipes, or profile tubes of smaller diameter, are normally supplied wound on a reel, so that connections between pipes are only necessary at relatively large distances. Larger pipes, known as collectors, can only be produced and transported in shorter lengths, for example 6 or 8 meters, and therefore require a greater number of flanged sleeves.

Les manchons à embottement sont, en régle générale, formés de pièces de forme, obtenus par un procédé de moulage par injection, et, pour cette raison, relavement comateux.  The embedding sleeves are, as a rule, formed of shaped parts, obtained by an injection molding process, and, for this reason, comatose wash.

L'invention a pour base le problème de fournir un dispositif pour relier l'un à l'autre des tuyaux ondulés qui puisse titre obtenu de façon relativement simple et économique. The invention is based on the problem of providing a device for connecting corrugated pipes to one another which can be obtained relatively simply and economically.

Ce résultat est obtenu grace au fait que trois éléments de coquille ondulés formant un arc de cercle d'environ 1800 sont décalés dans le sens du périmètre et péné trent dans les creux des ondulations des tuyaux et/ou de l'élément de coquille adjacent. This result is obtained by the fact that three corrugated shell elements forming an arc of a circle of about 1800 are offset in the direction of the perimeter and penetrate into the hollows of the corrugations of the pipes and / or of the adjacent shell element.

Dans le dispositif de l'invention, les éléments de coquille ou demi-coqi#ille peuvent être de la même matière que les tuyaux à relier. On coupe en deux, dans le sens axial, un tronçon de tuyau, pour obtenir deux éléments de coquille . On place trois éléments de ce type, décalés dans le sens du périmètre, en les enfon çant dans les ondulations des tuyaux à relier et/ou des éléments adjacents. Avec trois éléments décalés d'environ 1200 on obtient une liaison tout à fait sarde, qui peut même résister à certaines forces de traction. In the device of the invention, the shell or half-shell elements can be of the same material as the pipes to be connected. A section of pipe is cut in two, in the axial direction, to obtain two shell elements. Three elements of this type are placed, offset in the direction of the perimeter, by pushing them into the undulations of the pipes to be connected and / or of the adjacent elements. With three offset elements of around 1200, a completely Sardinian connection is obtained, which can even resist certain tensile forces.

On comprendra que les éléments de coquille peuvent correspondre à un arc de cercle un peu plus petit, ou un peu plus grand, que 1800. It will be understood that the shell elements may correspond to a slightly smaller, or slightly larger, arc than 1800.

Comme aucune opération de finition supplémentaire sur les tuyaux à relier n'est nécessaire lors de la préparation du dispositif conforme à l'invention, en dehors de l'obtention des éléments de coquille à partir du tuyau ondulé, ces éléments sont extrêmement fa cile à obtenir, Il n'y a cependant pas nécessité absolue que les ondulations des éléments de coquille conformes à l'invention soient identiques à celles des tuyaux à relier. En tous cas, il est nécessaire, cependant, que les dimensions des ondulations des éléments de coquille soient adaptées à celle des tuyaux. As no additional finishing operation on the pipes to be connected is necessary during the preparation of the device according to the invention, apart from obtaining the shell elements from the corrugated pipe, these elements are extremely easy to However, there is no absolute necessity that the undulations of the shell elements in accordance with the invention be identical to those of the pipes to be connected. In any case, it is necessary, however, that the dimensions of the corrugations of the shell elements be adapted to that of the pipes.

La longueur des éléments de coquille selon l'invention doit seulement être assez grande pour assurer une liaison convenable entre les tubes. Selon une modalité préférée de l'invention, elle peut correspondre à une double longueur d'ondulation. Be dispositif selon 11 invention convient notamment pour des tuyaux de diamètre trbe grand. De tels tuyaux présentent des ondulations prononcées avec de préférence des flancs raides. Il en résulte que les éléments de coquille ont une forte tendance à tenir en place par eux-mêmes et qu'une liaison, une fois confectionnée, ne s'ouvre pas d'elle même. The length of the shell elements according to the invention need only be large enough to ensure a suitable connection between the tubes. According to a preferred embodiment of the invention, it can correspond to a double wavelength. The device according to the invention is particularly suitable for pipes of large diameter. Such pipes have pronounced undulations with preferably steep sides. As a result, the shell elements have a strong tendency to hold in place by themselves and that a connection, once made, does not open by itself.

La liaison des tuyaux peut même être confectionnée avant la mise en place des tuyaux, sans qu'elle se défasse au cours de cette mise en place. The connection of the pipes can even be made before the installation of the pipes, without it becoming loose during this installation.

Il peut arriver que, par suite d'une fausse manoeuvre lors de la mise en place de tuyaux ondulés, il se produise une fissure ou une autre ouverture indésirée. It may happen that, as a result of a wrong operation when installing corrugated pipes, a crack or other unwanted opening occurs.

Un tel dégat peut être réparé de façon simple à l'aide du dispositif -de l'invention. On place les trois demi; coquilles autour du tuyau dans la région de la partie endommagée, de la manière décrite plus haut, et on les y fixe, si bien que la fissure ou ouverture est efficacement obturée.Such damage can be repaired in a simple manner using the device of the invention. We place the three half; shells around the pipe in the region of the damaged part, as described above, and they are fixed there, so that the crack or opening is effectively closed.

Les demi-coquilles du dispositif de l'invention peuvent être collées sur le ou les tubes, que ce soit pour confectionner une liaison ou pour obtenir une fissure ou une ouverture, lorsque'on désire une fixation plus solide ou une bonne étanchéité à l'eau. The half-shells of the device of the invention can be glued to the tube or tubes, whether to make a connection or to obtain a crack or an opening, when a more solid fixing or a good seal is required. water.

L'invention va maintenant être exposée plus en détail à l'aide des dessins annexés
la figure 1 montre, en coupe, une liaison entre deux tubes ondulés conforme à l'invention
la figure 2 montre une coupe selon la ligne 2-2 de la liaison de la figure 1.The invention will now be explained in more detail using the accompanying drawings.
Figure 1 shows, in section, a connection between two corrugated tubes according to the invention
FIG. 2 shows a section on line 2-2 of the connection in FIG. 1.

Deux tuyaux ondulés 10, 11, avec des sommets d'ondulation 12 et des fonds d'ondulation 13 sont placés bout-à-bout en 14. Les ondulations montrées à la figure 1 sont du type "à flancs droits" avec des flancs 15 qui sont à peu près perpendiculaire à l'axe des tuyaux. Ceux-ci sont en matière plastique extrudée, le tube recevant ses ondulations après extrusion. Two corrugated pipes 10, 11, with corrugation tops 12 and corrugation bottoms 13 are placed end-to-end at 14. The corrugations shown in FIG. 1 are of the "straight flank" type with flanks 15 which are roughly perpendicular to the axis of the pipes. These are made of extruded plastic, the tube receiving its undulations after extrusion.

Comme le montrent les figures 1 et 2, trois éléments de coquille 16, 17, 18 sont placés autour des tuyaux 10, 11. Ces éléments sont obtenus à partir de tubes de même forme et de me me diamètre nominal que les tubes 10 et 11, dans lesquels on a découpé des sections qui correspondent, dans la direction de l'axe, à sensiblement une double longueur d'onde. L'extension, dans le sens du périmètre, de chaque élément de coquille 16 à 18 est à peu près de 1800. Les éléments de coquille sont enfoncés à force dans les ondulations des tuyaux 10 et 11 et des éléments adjacents. On forme ainsi une liaison résistante à la traction et étanche entre les tubes 10 et 11.Cette liaison n'augmente que faiblement le diamètre extérieur des tuyaux 10 et 11, si bien qu'ils peuvent entre placés sans difficulté dans les fossés de drainage. L'obtention des trois éléments de coquille pour la liaison est peu conteuse, et en outre elle peut être effectuée sur le lieu de pose. Le démontage de la liaison peut être effectué par des opérations simples sans recourir à des outils coûteux. As shown in FIGS. 1 and 2, three shell elements 16, 17, 18 are placed around the pipes 10, 11. These elements are obtained from tubes of the same shape and with the same nominal diameter as the tubes 10 and 11 , in which sections have been cut which correspond, in the direction of the axis, to substantially a double wavelength. The extension, in the perimeter direction, of each shell element 16 to 18 is approximately 1800. The shell elements are forced into the undulations of the pipes 10 and 11 and of the adjacent elements. This forms a tensile and tight connection between the tubes 10 and 11. This connection only slightly increases the outside diameter of the pipes 10 and 11, so that they can easily be placed in the drainage ditches. Obtaining the three shell elements for the connection is inexpensive, and furthermore it can be carried out at the place of installation. The dismantling of the link can be carried out by simple operations without resorting to expensive tools.

Il est en outre possible, de façon simple, d'ajouter un nouvel élément de tuyau à la suite d'une canalisation et de le relier à l'extrémité de celle-ci, si elle a déjà été mise en place. En outre, on peut obturer une ouverture non désirée, résultant par exemple d'une avarie, et plus ou moins importante, à l'aide des demi-coquilles du type qu'on vient de décrire, ces demi-coquilles étant décalées d'environ 1200 au voisinage de l'ouverture. Les demi-coquilles peuvent en outre être collées sur le tuyau et sur les autres demi-coquilles pour fournir une étanchéité parfaite à l'eau.  It is also possible, in a simple way, to add a new pipe element following a pipe and to connect it to the end of the latter, if it has already been put in place. In addition, one can close an unwanted opening, resulting for example from damage, and more or less significant, using the half-shells of the type just described, these half-shells being offset by around 1200 in the vicinity of the opening. The half-shells can also be glued to the pipe and to the other half-shells to provide a perfect seal against water.
