Description

  

  Brevet     additionnel        subordonné    au brevet principal N  407 674    Procédé permettant de     ,parfaire    l'étanchéité d'une conduite de ciment  et dispositif pour la mise en     #uvre    de ce procédé    Le brevet principal N  407674 concerne un procédé  permettant de     parfaire    l'étanchéité d'une conduite de  ciment     -ét    un dispositif pour la mise en     couvre    de ce       procédé.     



  Ce procédé consiste, selon la revendication I de ce  brevet, à     utiliser    les regards ou chambres     disposés    de  place en place le long de la     conduite    pour y     introduire     un piston avec joint, épousant le     profil    intérieur des  tuyaux, à attacher des moyens de traction aux deux  extrémités de ce piston, à les     faire        sortir    chacun par un  regard, en     sorte    de pouvoir     tirer    le piston et le mou  voir dans les deux sens dans la conduite,

   à introduire  dans celle-ci et de l'un des     côtés    du piston une masse       semi-pâteuse,    capable de     faire    prise, à mouvoir le pis  ton contre cette masse en sorte de la pousser et     com-          primer        contre        un    élément par lequel on aura momenta  nément obturé la     conduite    et, en faisant effectuer au pis  ton     plusieurs        mouvements    de va-et-vient, à     provoquer     l'introduction de la masse de l'intérieur vers     l'extérieur     dans les joints défectueux.  



  Le cas peut se produire, où une conduite principale  à     réparer    est en     communication    avec des.     conduites          secondaires,    généralement de section plus petite, se dé  versant dans la     conduite    principale.  



  En appliquant le procédé, objet du brevet principal,  le piston, à son passage,     chassera    la masse     transportée     dans les conduites secondaires et     les,    obturera.  



  Pour parer à cet inconvénient, le     procédé    selon la  présente     invention    prévoit que l'on introduit dans cha  que conduite secondaire une tige souple se terminant  par un organe     pneumatiquement    gonflable, que l'on  amène au voisinage du     point    de raccordement des deux  conduites et gonfle     alors,    en     sorte    d'obturer l'entrée de  la conduite secondaire.  



  Le dispositif selon la présente invention, pour la       mise    en     couvre    de     ce    procédé, est caractérisé en ce qu'il  comporte un accessoire formé d'une     tige    souple compo-         sée    d'au moins un élément se terminant par un organe       pneumatiquement        gonflable    relié à un tuyau d'alimen  tation.  



  Comme élément de tige souple, on peut choisir une  perche de bambou, une tige en matière plastique, par  exemple.  



  L'organe     pneumatiquement        gonflable    pourra être  une vessie, en caoutchouc ou autre matière appropriée,  fixée à     l'extrémité    de l'élément considéré, dont l'autre  extrémité pourra comporter un moyen d'assemblage à  vis ou à baïonnette, permettant de l'accoupler à un  second élément, et ainsi de suite, jusqu'à obtenir la  longueur     désirée.     



  La souplesse de la ou des tiges     utilisées    permettra  de les introduire dans ces conduites     secondaires,    non rec  tilignes.



  Additional patent subordinate to main patent N 407 674 Process for perfecting the tightness of a cement pipe and device for implementing this process The main patent N 407674 relates to a process for perfecting the sealing of a cement pipe. a cement pipe -et a device for setting this process cover.



  This process consists, according to claim I of this patent, in using the manholes or chambers arranged from place to place along the pipe to introduce therein a piston with seal, matching the internal profile of the pipes, in attaching traction means to the pipes. two ends of this piston, to make them each come out through a look, so as to be able to pull the piston and the slack to see in both directions in the pipe,

   to introduce into it and from one of the sides of the piston a semi-pasty mass, capable of setting, to move the udder against this mass so as to push it and compress against an element by which we will have momentarily blocked the pipe and, by causing the udder to perform several back and forth movements, causing the introduction of the mass from the inside to the outside in the defective joints.



  The case may occur where a main to be repaired is in communication with. Secondary pipes, generally of smaller cross-section, emptying into the main pipe.



  By applying the process, the subject of the main patent, the piston, as it passes, will drive out the mass transported in the secondary pipes and block them.



  To overcome this drawback, the method according to the present invention provides that one introduces into each secondary pipe a flexible rod terminating in a pneumatically inflatable member, which is brought to the vicinity of the point of connection of the two pipes and inflated. then, in order to block the entrance to the secondary pipe.



  The device according to the present invention, for the implementation of this process, is characterized in that it comprises an accessory formed of a flexible rod composed of at least one element terminating in a pneumatically inflatable member connected to the device. a supply pipe.



  As a flexible rod element, one can choose a bamboo pole, a plastic rod, for example.



  The pneumatically inflatable member may be a bladder, made of rubber or other suitable material, fixed to the end of the element in question, the other end of which may include a screw or bayonet assembly means, allowing the mate with a second element, and so on, until the desired length is obtained.



  The flexibility of the rod (s) used will allow them to be introduced into these secondary conduits, which are not rec tilinear.
