    摘要： 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.

    摘要： The apparatus for consolidating soil comprises a mixing-disaggregation tool (15, 113) which is applied to the lower end of a vertical rotating shaft (7, 108) which, after being placed at a point of the region of the soil to be consolidated, is caused to advance into the soil with the simultaneous introduction of air and, if necessary, of water. Once the required depth has been reached, a consolidating agent is introduced in the soil through appropriate holes (19, 24, 183) defined proximate to the disaggregation-mixing tool (15, 113) while the lifting of the tools is simultaneously performed.

    摘要： The process starts with digging a trench (10) of adequate depth in the slope (8) of the embankment (1) of the existing roadway at a distance corresponding to the widening. A wall (12) is then built in the trench by means of prefabricated elements or by on-site casting, and is subsequently anchored to the road embankment (1) by means of tension elements (17). The wall (12) rises substantially to the level of the roadway so as to define a channel (15) which is then filled with stabilized material, on which the road paving is completed up to the wall.
