Abstract

A method for the preventive consolidation of tunnel excavations by using the protective umbrella techinique, exploiting an equipment comprising: a metallic tube (1) of reinforcement, a tubular rod (12) provided with nozzles, a piercing bit (4) and a double rotary unit. The process comprises the following phases: a) mainly sub-horizontal drilling of the soil with the piercing bit (4) coaxially contained inside the tube (1), said tube (1) and said rod (2) being rotated one opposite to each other by a rotary unit; b) injection of pressurized liquid mixtures through the nozzles of the rod (2) with the removal of the finest part of the soil that is being consolidated; c) extraction of the rod from the inside of the tube. <IMAGE>
