Abstract

UN PREMIER ET UN SECOND ELEMENTS TUBULAIRES SITUES SOUS L'EAU SONT ASSEMBLES DE FACON QUE LA SURFACE EXTERNE DU PREMIER ET LA SURFACE INTERNE DU SECOND SOIENT ESPACEES POUR DELIMITER UNE CAVITE ANNULAIRE. CETTE CAVITE EST FERMEE, NETTOYEE ET SECHEE ET REMPLIE D'UN GAZ SOUS UNE PRESSION SUPERIEURE A LA PRESSION DE L'EAU ENVIRONNANTE. LA PRESSION REGNANT DANS LA CAVITE EST REDUITE AVANT DE FAIRE EXPLOSER UNE CHARGE EXPLOSIVE A L'INTERIEUR DU PREMIER ELEMENT TUBULAIRE AFIN DE SOUDER ENSEMBLE LES ELEMENTS. LA CAVITE PEUT ETRE SUBDIVISEE EN PLUSIEURS ZONES PAR D'AUTRES JOINTS, LA PRESSION REGNANT DANS LES ZONES POUVANT ETRE REGLEE SEPAREMENT AFIN DE POUVOIR COMMANDER LA DIFFERENCE DE PRESSION DE PART ET D'AUTRE DE CHAQUE JOINT. APPLICATION A LA POSE DES CANALISATIONS SOUS-MARINES.
