Processing station of the sludge associated has a tunnel boring machine has a leading edge pressurizes and method of managing such a station.

摘要

This processing station of the sludge associated with a tunnel boring machine (1) to the leading edge pressurized, comprises at least a first means (6) of regeneration of the sludge (b) from the leading edge of the tunnelling machine, a second means (7) for the preparation of the fresh mud known as sludge mother (b1), a third means (8) for the preparation of a mixture of sludge to be used in the leading edge of said sludge pickling (b2), on the basis of the sludge (b0, b1) from the first (6) and second means (7), a fourth means (12) of supply of the leading edge in the mud pickling (b2), a fifth means (13) of the collection and evacuation of the sludge (b3) is not used, and not to be regenerated, a sixth means (14), which is interposed between the first (6) and third means (8) and adapted to direct it towards the fifth means (13), a part of the sludge (b0, b1) from the third means (8). The sixth means (14) is adapted to direct, so as to be adjustable, to the fifth means (13), only a part of the sludge (b0) regenerated from the first means (6).
