Description
BATARDEAU DEMONTABLE POUR L'ENTRETIEN DES
CANAUX D'EXPLOITATION HYDRAULIQUE
La présente invention a pour objet un batardeau démontable pour l'entretien des canaux d'exploitation hydraulique.REMOVABLE COVER FOR THE MAINTENANCE OF
HYDRAULIC OPERATING CHANNELS
The present invention relates to a removable cofferdam for the maintenance of hydraulic operating channels.
I1 est destiné à équiper les entreprises chargées de 11 entretien des canaux hydrauliques de tous types, aussi bien navigables ou d'irrigation que de distribution d'eau potable ou d'eau de refroidissement pour centrales électriques ou autres industries. It is intended to equip companies responsible for the maintenance of hydraulic channels of all types, both navigable or irrigation as well as the distribution of drinking water or cooling water for power stations or other industries.
La plupart des pays, et en particulier la
FRANCE, sont équipés d'importants réseaux de canaux hydrauliques représentant des milliers de kilomètres qu'il faut entretenir régulièrement.Most countries, and in particular the
FRANCE, are equipped with large networks of hydraulic canals representing thousands of kilometers that must be maintained regularly.
Ces canaux ont le plus souvent un profil standardise caractérisé par un fond plat et des berges inclinées
A l'heure actuelle, lorsqu'il faut colmater des fissures, reprendre des joints ou refaire une partie des berges, il faut interrompre l'écoulement de l'eau dans la portion concernée du canal pendant une periode qui, selon les travaux à effectuer, peut s'étaler sur quelques heures ou plusieurs jours, voire plusieurs semaines, ce qui entraîne une gêne considérable pour les utilisateurs et un manque à gagner parfois considérable pour les exploitants.These channels most often have a standardized profile characterized by a flat bottom and inclined banks
At present, when it is necessary to patch up cracks, resume joints or redo part of the banks, it is necessary to interrupt the flow of water in the concerned portion of the canal for a period which, depending on the work to be carried out , can be spread over a few hours or several days, even several weeks, which causes considerable discomfort for users and sometimes considerable loss of profit for operators.
Le dispositif selon la présente invention supprime tous ces inconvénients. En effet, il permet d'effectuer les travaux d'entretien sur les berges d'un canal sans interrompre le service de ce dernier et peut être monté, démonte, mis en place et déplacé très rapidement. The device according to the present invention eliminates all these drawbacks. Indeed, it allows maintenance work to be carried out on the banks of a canal without interrupting the service of the latter and can be assembled, dismantled, put in place and moved very quickly.
Il est constitué par la combinaison d'un ensemble démontable en métal léger soudé, composé de deux parois latérales dont la forme de l'arête inférieure correspond à la forme de la berge du canal, et d'un fond technique vertical rectangulaire équipe d'une pompe de vidange, d'une vanne de remplissage ainsi que de deux roulettes escamotables, ledit fond technique délimitant avec les deux parois latérales susdites et la berge un espace de travail pouvant être mis hors d'eau grâce à la pompe de vidange, le fond technique et les parois latérales etant equipés en partie inférieure de joints d'étanchéité démontables et en partie supérieure d'éléments creux externes formant, une fois le dispositif assemblé, un caisson étanche permettant à l'ensemble de flotter et pouvant être vidé d'eau grâce à une source d'air comprimé actionnant également les roulettes escamotables et la vanne de remplissage. It is constituted by the combination of a dismountable assembly in welded light metal, composed of two side walls whose shape of the lower edge corresponds to the shape of the bank of the canal, and of a vertical technical bottom rectangular team of a drain pump, a filling valve as well as two retractable rollers, said technical bottom defining with the two aforementioned side walls and the bank a working space which can be put out of water thanks to the drain pump, the technical background and the side walls being equipped in the lower part with removable seals and in the upper part with external hollow elements forming, once the device has been assembled, a watertight box allowing the assembly to float and capable of being emptied of water thanks to a source of compressed air also actuating the retractable rollers and the filling valve.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention

La figure 4 montre, vu de dessus, le dispositif en place dans un canal. Figure 4 shows, seen from above, the device in place in a channel.
La figure 5 represente le fond technique vu de l'intérieur du dispositif, suivant la flèche A de la figure 2. FIG. 5 represents the technical background seen from the interior of the device, according to arrow A in FIG. 2.
La figure 6 est un détail agrandi montrant un système d'attache rapide de montage. Figure 6 is an enlarged detail showing a quick mounting mounting system.
La figure 7 est une coupe verticale partielle du fond technique, suivant les flèches B-B de la figure 5, montrant à une autre échelle une roulette escamotable ainsi que le joint d'étanchéité inférieur. Figure 7 is a partial vertical section of the technical background, along the arrows B-B of Figure 5, showing on another scale a retractable roller and the lower seal.
Le dispositif, figures 1 à 7, est constitué de deux parois latérales 1 symétriques, d'une fond technique 2 vertical et d'une traverse 3, montée entre les deux parois latérales, à l'opposé du fond technique pour maintenir leur écartement. The device, Figures 1 to 7, consists of two symmetrical side walls 1, a vertical technical bottom 2 and a cross 3, mounted between the two side walls, opposite the technical bottom to maintain their spacing.
Les parois latérales 1 sont faites d'une plaque préférentiellement en aluminium avec raidisseurs soudés (non representés), en forme de triangle ou de trapèze rectangle, le côté non perpendiculaire constituant l'arête inférieure formant avec l'horizontale un angle identique à celui de la berge 20 du canal. Cette arête inferieure est équipée d'un double joint d'étanchéité démontable, formé d'une lèvre souple 4 extérieure et d'un joint interieur 5 en mousse d'élastomère, monté dans un profilé en forme de U. La possibilité de démonter le joint d'étanchéité permet d'intercaler un élément de paroi de forme appropriée, dans le but d'adapter le système à plusieurs profils de canaux. The side walls 1 are made of a plate preferably made of aluminum with welded stiffeners (not shown), in the shape of a triangle or a rectangular trapezoid, the non-perpendicular side constituting the lower edge forming with the horizontal an angle identical to that of bank 20 of the canal. This lower edge is equipped with a removable double seal, formed by a flexible outer lip 4 and an inner seal 5 made of elastomer foam, mounted in a U-shaped profile. The possibility of dismantling the seal allows an appropriately shaped wall element to be inserted, in order to adapt the system to several channel profiles.
Le fond technique 2 est une plaque rectangulaire constituée exactement de la même maniere que les parois latérales. Sa face interne regroupe tous les équipements techniques du système avec leurs commandes, et en particulier deux roulettes escamotables 6, une pompe de vidange 7 et une vanne de remplissage 8. Ces trois dispositifs sont actionnés par de l'air comprimé provenant d'une source exterieure par l'intermédiaire de deux tubes 9. Un troisième tube 10, aboutissant à l'extérieur de l'espace de travail, est raccordé à la sortie de la pompe de vidange 7. The technical base 2 is a rectangular plate constituted in exactly the same way as the side walls. Its internal face brings together all the technical equipment of the system with their controls, and in particular two retractable rollers 6, a drain pump 7 and a filling valve 8. These three devices are actuated by compressed air from a source exterior by means of two tubes 9. A third tube 10, terminating outside the working space, is connected to the outlet of the drain pump 7.
Un caisson étanche, formé d'éléments creux tubulaires 11, 12 fixes en partie haute et à l'extérieur des parois laterales 1 et du fond technique 2, permet au batardeau selon l'invention de flotter. Ce caisson étanche est raccorde à la source d'air comprimé par l'intermédiaire de vannes de commande et est pourvu de clapets de remplissage automatiques laissant pénétrer l'eau dès que la pression à l'intérieur du caisson étanche tombe au-dessous d'une valeur prédéterminée, par exemple 0,3 bar, ce qui permet de remplir ou vider le caisson à volonté par simple action sur l'alimentation d'air comprime. A sealed box, formed by hollow tubular elements 11, 12 fixed in the upper part and outside the side walls 1 and the technical bottom 2, allows the cofferdam according to the invention to float. This waterproof case is connected to the compressed air source by means of control valves and is provided with automatic filling valves allowing water to penetrate as soon as the pressure inside the waterproof case falls below a predetermined value, for example 0.3 bar, which makes it possible to fill or empty the box at will by simple action on the compressed air supply.
Le batardeau est amené à pied d'oeuvre démonté, ce qui, en raison de la légèreté du matériau utilisé pour ses composants, peut se faire à l'aide d'un moyen de transport et d'appareils de manutention de capacités limitées, est assemblé sur place en tres peu de temps grâce à des attaches rapides 13 montées sur les parois laterales 1 s'enclenchant dans les etriers réglables 14 fixés sur le fond technique 2. Le positionnement des éléments est facilité par des tétons de centrage 15. L'étanchéité est assurée grâce à des goulottes 16 contenant un joint souple 17, fixées sur le fond technique 2, et dans lesquelles s'ajustent les arêtes verticales des parois latérales 1. The cofferdam is brought to work dismantled, which, due to the lightness of the material used for its components, can be done using a means of transport and handling equipment of limited capacity, is assembled on site in a very short time thanks to quick fasteners 13 mounted on the side walls 1 snapping into the adjustable stirrups 14 fixed on the technical background 2. The positioning of the elements is facilitated by centering pins 15. The sealing is ensured by means of troughs 16 containing a flexible seal 17, fixed to the technical base 2, and in which the vertical edges of the side walls 1 are adjusted.
Une fois le système monté, les roulettes escamotables 6 sont sorties et on laisse le batardeau descendre dans le canal, retenu par des câbles 18. Lorsque sa position d'intervention, est atteinte, la vanne de remplissage 8 est fermée et la pompe de vidange 7 est mise en route, jusqu'à ce que l'espace de travail soit vidé de son eau. Les travaux à effectuer peuvent alors commencer, la pompe étant remise en route dès que l'eau s'infiltre par les joints inférieurs dont l'étanchéité a peu de chance d'être absolue, en raison de l'état de surface du fond du canal. Once the system has been mounted, the retractable rollers 6 are out and the cofferdam is left to descend into the channel, retained by cables 18. When its intervention position is reached, the filling valve 8 is closed and the drain pump 7 is started up, until the workspace is emptied of its water. The work to be carried out can then begin, the pump being restarted as soon as water infiltrates through the lower seals, the sealing of which is unlikely to be absolute, due to the surface condition of the bottom of the channel.
Lorsque les travaux doivent être poursuivis à un autre endroit du canal, l'air comprimé est envoyé dans le caisson étanche 11, 12, ce qui provoque sa vidange par les clapets automatiques, et la batardeau se met à flotter. I1 n'y a plus qu'à le déplacer par hâlage jusqu'à son nouvel emplacement, puis à couper l'alimentation en air comprimé du caisson étanche qui se remplit d'eau et provoque l'échouage du batardeau qu'il suffira de vider à l'aide de la pompe de vidange 7. When the work must be continued at another location in the canal, the compressed air is sent into the watertight box 11, 12, which causes it to be emptied by the automatic valves, and the cofferdam begins to float. It only has to be moved by tanning to its new location, then to cut off the compressed air supply to the watertight box which fills with water and causes the cofferdam to ground. empty using the drain pump 7.
A aucun moment le débit du canal n'a dû être interrompu, tout au plus a-t-il dû être legerement diminué pour que le niveau de l'eau n'atteigne pas le haut du batardeau. At no time should the flow of the canal have been interrupted, at most it should have been slightly decreased so that the water level did not reach the top of the cofferdam.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
