Hydromill Module SH 50 Diaphragm/Slurry walls Soilmec [150m & 250 mt deep] 

Diaphragm walls are common practice in civil engineering as part of or as aids to the building of civil and hydraulic structures.

Basically, a trench is excavated in the ground, generally in the presence of a stabilizing fluid, and it is then back-filled with an appropriate material. The material is cut and loosened with two cutting wheels mounted at the bottom of a steel frame and rotating in opposite directions.

The loosened or cut material mixes into the bentonite slurry suspension which is pumped from the trench by a very powerful suction pump mounted on the hydromill and conveyed to a mud treatment unit plant for cleaning. Hydromill offers a greater rate of penetration for the excavation than most any other type of diaphragm wall technique and also offers the highest level of accuracy in verticality.

Il modulo idrofresa SH 50 è costituito da un robusto telaio in acciaio sul quale sono montati due unità di perforazione contro-rotanti e indipendenti. Con l’obiettivo di correggere la deviazione dalla verticale sono state progettate sulla superficie del modulo fresante delle alette mobili indipendenti.
Soilmec ha sviluppato un sistema di rotazione del modulo fresante per la realizzazione di pannelli a T in quanto in cantieri con poco spazio disponibile la variazione dell’orientamento della macchina può essere un’operazione molto difficile portando a un notevole aumento di costo e di tempo di realizzazione dell’opera.
