An improvement of patent No. 84-18690 concerning a process for constructing linear works in ground covered with compacted or decompacted soil and the mass treatment of the ground obtained by juxtaposition of these works. The improvement consists in using one or more auxiliary tubes fixed on the main tube forming the core of the tool to bring or inject additional materials into the ground. For example one can form a pile, micropile or tie with an enlarged base of a greater diameter than that of the tool used. <IMAGE> |
