Abstract

La présente invention concerne un procédé de réalisation d’un forage, notamment d’un forage de grand diamètre, le long d’un axe de forage dans un terrain, comprenant des étapes de :i) réalisation d’un forage d’exploration le long de l’axe de forage, le forage d’exploration réalisé présentant une paroi interne,ii) creusement d’un interstice dans le terrain, l’interstice étant de forme sensiblement cylindrique centrée sur l’axe de forage,iii) insertion d’une paroi latérale d’un panier de découpe dans l’interstice, la paroi entourant des lames du panier de découpe, les lames s’insérant à l’intérieur du forage d’exploration,iv) actionnement des lames pour détacher une portion de terrain confinée à l’intérieur de la paroi latérale, ladite portion s’étendant jusqu’aux lames depuis une paroi de tête du panier,v) évacuation du panier de découpe et extraction de la portion de terrain, de sorte à creuser le forage. Figure pour l’abrégé : Figure 2cThe present invention relates to a method of producing a borehole, in particular a large-diameter borehole, along a drilling axis in a field, comprising the steps of: i) carrying out an exploration borehole on the ground. along the drilling axis, the exploration drilling carried out having an internal wall, ii) digging of an interstice in the ground, the interstice being of substantially cylindrical shape centered on the drilling axis, iii) insertion of 'a side wall of a cutting basket in the gap, the wall surrounding blades of the cutting basket, the blades fitting inside the exploration borehole, iv) actuation of the blades to detach a portion of land confined within the side wall, said portion extending to the blades from a head wall of the basket, v) evacuation of the cutting basket and extraction of the portion of land, so as to dig the borehole.
