Abstract

LE PROCEDE SELON L'INVENTION CONSISTE A ENTRAINER LE TREPAN A UNE FREQUENCE DE PERCUSSION ELEVEE ET AVEC UNE ENERGIE FAIBLE PAR CHOC SANS ROTATION DU TREPAN AFIN QUE CELUI-CI NE SOIT PAS DETERIORE, LE TREPAN COMPORTANT UN MANCHON DE COUPE 22 RELIE PAR UN MANCHON D'ACCOUPLEMENT 26 A UNE TIGE DE FORAGE 24 ACCOUPLEE A UN MECANISME DE FORAGE PAR PERCUSSION, LE MANCHON 22 COMPORTANT UNE TIGE 27 POUR BRISER DES DEBRIS ENTRAINES PAR UNE CIRCULATION D'AIR ARRIVANT PAR DES TROUS LATERAUX 28 ET UN REBORD FAIBLE FORME PAR MATAGE A L'EXTREMITE 29 DU TREPAN POUR DEPASSER LATERALEMENT AUTOUR DU BORD.THE PROCESS ACCORDING TO THE INVENTION CONSISTS OF DRIVING THE TREPAN AT A HIGH PERCUSSION FREQUENCY AND WITH LOW ENERGY BY IMPACT WITHOUT ROTATION OF THE TREPAN SO THAT THE latter IS NOT DETERIORED, THE TREPAN CONTAINING A CUTTING SLEEVE 22 CONNECTED BY A SLEEVE COUPLING 26 TO A DRILLING ROD 24 COUPLED TO A PERCUSSION DRILLING MECHANISM, SLEEVE 22 INCLUDING A ROD 27 FOR BREAKING DEBRIS DRAWN BY A CIRCULATION OF AIR ARRIVING THROUGH LATERAL HOLES 28 AND A WEAK EDGE SHAPED BY MATAGE AT THE END 29 OF THE TREPAN TO GO LATERALLY AROUND THE EDGE.
