Abstract (en)
System for evacuating mud produced by a digging machine (10), wherein said machine comprises a digging head (11) arranged to dig the soil, a flexible bearing element (12) arranged to support the digging head during the normal operation of the machine itself, a winch (14) and a drum, about which at least part of such a flexible element (12) can be wound. Such a system comprises a tank (V) for containing a fluid for mixing and removing the deposits being taken from the tank through a pumping station (P) and being introduced into the excavation in at least one supply duct (2). A mud extraction pump (4) directly associated with such a digging head (11), extracts the mud from the excavation via a mud evacuation tube (F). The system is characterised in that it comprises at least one ejection duct (5) that receives the light fluid for mixing and removing the deposits from such a supply duct (2) to carry it near to the digging head (11), in such a way that said light fluid for mixing and removing the deposits is conveyed towards the mud evacuation tube (F) by at least part of the stabilising fluid.
