Abstract (en)
[origin: WO8903458A1] The invention relates to an improvement to the invention disclosed in the French patent n DEG 84-18690 relating to a construction method for linear works in compacted or decompacted grounds and the mass treatments of grounds obtained by juxtaposition of said works. The improvement comprises the utilization of one or a plurality of auxiliary tubes (20, 21) fixed to the main tube (19) forming the web of the tool to feed or inject earthwork materials into the ground. For example it is possible to make a pile, a micropile or a tie-rod with enlarged base having a diameter bigger than the diameter of the tool used.
