Method and apparatus for forming a grommet assembly to seal and reinforce holes through a cured in place liner for securing a cable. A first grommet base having a centrally located aperture with wedge shaped grooves is positioned on one side of the hole. A barrel having two opposed sets of wedge shaped projections is inserted into the grommet base and a second grommet base is placed on the barrel and pushed towards the liner until the second base firmly contacts the top surface of the liner and compresses the liner against the first base. The wedge shaped projections on the barrel and the complimentary grooves in the central apertures of the grommet bases prevent the barrel from being pulled out of either grommet base. The end of the barrel which projects out above the second base is cut off flush with the top surface. A hydraulic press to install the grommet assembly is also disclosed.

La présente invention concerne un procédé et un appareil pour former un assemblage d'AEillet pour sceller et renforcer des trous dans une garniture durcie sur place afin de sécuriser un câble. Une première base d'AEillet ayant une ouverture centrale avec des rainures cunéiformes est positionnée sur un côté du trou. Un cylindre ayant deux ensembles opposés de projections cunéiformes est inséré dans la base d'AEillet et une seconde base d'AEillet est placée sur le cylindre et poussée vers la garniture jusqu'à ce que la seconde base soit fermement en contact avec la surface supérieure de la garniture et comprime la garniture contre la première base. Les projections cunéiformes sur le cylindre et les rainures complémentaires dans les ouvertures centrales des bases d'AEillet empêchent le cylindre d'être sorti de l'une des bases d'AEillet. L'extrémité du cylindre qui dépasse au-dessus de la seconde base est découpée au niveau de la surface supérieure. La présente invention concerne également une presse hydraulique destinée à installer l'assemblage d'AEillet.
