Comacchio MC 30 Jetgrouting

Comacchio MC 30 installing jet-grouting columns as part of the renovation of the TCR Dante dock. The jet-grouting treatment is the final part of the project that has involved the creation of a new combi-wall, followed by the construction of 1200 mm bored piles to support the new dock structure. The consolidation with single fluid jet-grouting technique involves the installation of 6 rows of 800 mm columns, spaced at 2.5 m, extending along the 300 m long dock. Pre-cutting with water is used due to the presence of a silty clay layer. The project envisages the installation of a total of 126 columns with a length of 16.7 m. Work is running smoothly thanks to the Comacchio MC 30, reaching production rates of 12 columns per day.
