    placer un tube creux (1) avec des buses dans un site d'excavation;
    positionner une tige creuse (2) coaxialement dans le tube creux (1), un espace annulaire (5) étant défini entre la tige (2) et le tube (1), et ledit tube creux étant muni à une de ses extrémités d'un outil de forage (3);
    faire tourner le tube creux (1) et la tige creuse (2) pour creuser le matériau di site d'excavation à l'aide desdits moyens de forage (3);
    injecter simultanément un mélange fluidique sous houte pression dans le site d'exavation, par ladite tige creuse (2), a travers les buse réparties radialement, à proximité des moyens de forage (3) pendant la rotation du tube creux (1) et de la tige creuse (2), en élargissant par cela le diamètre de l'excavation, une partie de la fraction la plus fine du sol creusé étant évacuée du site d'excavation par ledit espace annulaire (5), et ledit mélange liquide se mélangeant avec la partie restante du matériau creusé pour former une colonne (6) de sol et de mèlange liquide qui se solidifie autour du tube (1) derrière l'outil de forage, pendant sa progression dans le sol; et
    extraire ladite tige (2) du tube creux (1) aprés qu'il a obtenu la longueur voulue de la colonne (6).
  2. Procédé selon la revendication 1, caractérisé en ce que, pendant l'excavation, le tube (1) et la barre (2) sont contraints à avancer simultanément, tout en étant mis en rotation en sens inverse l'un de l'autre.
