Procédé et équipement pour le percement, par l'intérieur des canalisations, d'une gaine d' étanchéité à l'endroit des branchements des abonnésMethod and equipment for drilling, through the interior of pipes, a sealing sheath at the location of subscribers' connections
Procédé et équipement pour te percement,, par L'intérieur des canalisations,, d'une gaine d'étanchéité à l'endroit des branchements des abonnés.Method and equipment for piercing, through the interior of pipes, a sealing sheath at the location of subscribers' connections.
La présente invention concerne en général Les canalisations d'eau et de gaz rendues étanches par L'application sur toute la surface interne de la canalisation d'une gaine d'étanchéité et est relative au percement par l'intérieur de cette gaine à l'endroit des branchements des abonnés.The present invention generally relates to water and gas pipes made watertight by the application over the entire internal surface of the pipe of a sealing sheath and relates to the piercing from the inside of this sheath to the location of subscriber connections.
Ce percement par L'intérieur s'effectue actuellement par des moyens mécaniques mais, d'une part, sur petits diamètres de branchements ce percement mécanique s'avère quasi impossible, du fait que le positionnement de L'outil de forage dans L'axe du branchement est très difficile à réaliser et, d'autre part, dans Les canalisations maitresses de petit calibre, ce percement s'avère impossible pour raison d'encombrement des moteurs et par suite de Leur manque de puissance.This internal drilling is currently carried out by mechanical means, but, on the one hand, on small connection diameters this mechanical drilling is almost impossible, because the positioning of the drilling tool in the axis connection is very difficult to achieve and, on the other hand, in small gauge master pipes, this drilling proves to be impossible due to the size of the motors and as a result of their lack of power.
Il faut encore noter à côté de ces inconvénients que le percement mécanique ne permet pas d'éliminer l'épaulement circonférentiel résiduel de la gaine à l'endroit du percement. De ce fait, le diamètre de percement se trouve être réduit par rapport au diamètre du branchement.It should also be noted next to these drawbacks that the mechanical piercing does not make it possible to eliminate the residual circumferential shoulder of the sheath at the location of the piercing. Therefore, the drilling diameter is reduced compared to the diameter of the connection.
De plus, le percement mécanique ne permet pas à coup sûr de retirer La capsule découpée et l'ensemble de la résine de collage aggloméré dans Le branchement.In addition, the mechanical piercing does not allow for sure to remove the cut capsule and all of the bonding resin agglomerated in the connection.
Pour remédier à ces inconvénients il a paru avantageux suivant l'invention de créer un procédé de percement caractérisé en ce qu'il consiste en un forage par thermofusion.To remedy these drawbacks, it seemed advantageous according to the invention to create a drilling process characterized in that it consists of drilling by thermofusion.
Pour réaliser Le procédé un équipement de forage suivant l'invention consiste en un robot de forage déplaçable dans la canalisation et portant une tête de forage par thermo-fusion, commandée en pénétration et en giration.To carry out the method a drilling equipment according to the invention consists of a drilling robot which can be moved in the pipeline and which carries a drilling head by heat fusion, controlled in penetration and in gyration.
Suivant L'invention l'extrémité de travail de la tête de forage est conique et son embase est élargie. L'invention est décrite maintenant avec plus de détails sur La base du dessin annexé, à titre d'exemple uniquement, montrant en :According to the invention the working end of the drilling head is conical and its base is enlarged. The invention is now described in more detail on the basis of the attached drawing, by way of example only, showing in:
Figure 1 une vue schématique de profil d'un robot de forage, destiné à réaliser Le procédé suivant l'invention, en position de repos à l'endroit d'un branchement, etFIG. 1 a schematic profile view of a drilling robot, intended to carry out the method according to the invention, in the rest position at the location of a connection, and
Figure 2 une vue analogue à celle de figure 1, le robot . étant en position finale de forage.Figure 2 a view similar to that of Figure 1, the robot. being in the final drilling position.
Comme on le voit au dessin Le robot de forage 1 est monté sur roues 1' pour se déplacer dans La canalisation 2 et porte une tête de forage par thermo-fusion 3 par l'intermédiaire d'un système articulé commandé d'une part par un moteur 4 en pénétration et d'autre part par un moteur 5 en giration.As seen in the drawing The drilling robot 1 is mounted on wheels 1 'to move in the pipe 2 and carries a drilling head by heat fusion 3 by means of an articulated system controlled on the one hand by a motor 4 in penetration and on the other hand by a motor 5 in gyration.
Le système articulé est avantageusement représenté au dessin par un système de losange articulé composé d'une vis sans fin 6 et de deux Leviers 7, 7' reliés chacun d'une part à Ladite vis 6 et d'autre part à la tête de forage 3. aThe articulated system is advantageously represented in the drawing by an articulated diamond system composed of an endless screw 6 and two levers 7, 7 'each connected on the one hand to said screw 6 and on the other hand to the drilling head. 3.a
Le robot de forage réalise une forte pénétration de la tête de forage grâce à la course obtenue par le système articulé, qui permet de Limiter la force nécessaire du moteur 4 de mise en oeuvre de la pénétration.The drilling robot achieves a strong penetration of the drilling head thanks to the stroke obtained by the articulated system, which makes it possible to limit the necessary force of the motor 4 for implementing the penetration.
Avec L'entraînement motorisé par le moteur 5 - de faible puissance, permettant ici aussi la miniaturisation - la tête de forage 3 peut se déplacer en giration.With the motor-driven drive 5 - of low power, here also allowing miniaturization - the drilling head 3 can move in gyration.
La tête de forage 3 présente une extrémité de travail 3' conique, de manière à permettre une auto-pénétration dans le branchement à dégager 8 même en cas de centrage ou positionnement imparfait.The drilling head 3 has a conical working end 3 ′, so as to allow self-penetration into the branch to be released 8 even in the event of imperfect centering or positioning.
Alors que la tête de forage 3 possède un diamètre légèrement inférieur au diamètre du branchement 8, elle présente une embase 3" élargie destinée par fusion à dégager entièrement Le branchement 8 et à supprimer l'épaulement de gaine résiduel 9.While the drilling head 3 has a diameter slightly less than the diameter of the branch 8, it has an enlarged base 3 "intended by fusion to completely release the branch 8 and to remove the residual sheath shoulder 9.
Grâce à une résistance incorporée 10 la tête de forage a la propriété de monter à des températures suffisamment élevées pour permettre la fusion de la portion de gaine et la calcination des résines de collage. Ces températures sont réglables et mesurables.Thanks to a built-in resistor 10 the drilling head has the property of rising to temperatures high enough to allow the melting of the sheath portion and the calcination of the bonding resins. These temperatures are adjustable and measurable.
Sur le robot 1 est monté dans l'axe de la tête de forage 3 un dispositif à fin faisceau lumineux 11, commandé sous vision caméra. Ce fin faisceau lumineux permet de positionner le robot et plus particulièrement la tête de forage face au branchement à dégager 8 sans risque d'altérer la gaine 11 à un endroit inopportun.On the robot 1 is mounted in the axis of the drilling head 3 a device with a fine light beam 11, controlled under camera vision. This fine light beam makes it possible to position the robot and more particularly the drilling head facing the connection to be released 8 without the risk of altering the sheath 11 at an inappropriate location.
