Abstract
L'INVENTION CONCERNE UN SABOT DE CIMENTATION A CLAPET DESTINE A ETRE REINTRODUIT DANS UN FORAGE SOUS-MARIN, AINSI QUE SON PROCEDE D'UTILISATION. CE SABOT, CONSTITUE DE DEUX ENVELOPPES CYLINDRIQUES COAXIALES ET D'UNE AME EN CIMENT, EST ASSUJETTI A UNE COLONNE DE CUVELAGE QUI LE FAIT DESCENDRE A PROXIMITE DU PUITS A RETROUVER. LE HAUT DE SON ENVELOPPE INTERIEURE SE RACCORDE A UNE COLONNE DE CIMENTATION PAR LAQUELLE ON Y INTRODUIT UN APPAREIL DE GUIDAGE PAR TELEVISION OU ULTRASONS. L'ENVELOPPE INTERIEURE FORME LATERALEMENT LE LOGEMENT D'UN CLAPET SPHERIQUE DONT LA MASSE VOLUMIQUE EST SUPERIEURE A CELLE DE L'EAU ET INFERIEURE A CELLE DU CIMENT. REPOUSSE PAR LA PRESSION DE CE DERNIER, CE CLAPET VIENT OBSTRUER AXIALEMENT CETTE ENVELOPPE DANS LAQUELLE IL COOPERE AVEC UN BOUCHON DE CIMENTATION. APPLICATION AUX TECHNIQUES DE FORAGE SOUS-MARIN.
