SYSTEM FOR NON-DESTRUCTIVE PENETRATION OF A SUBSTRATE

摘要

The system (10, 100, 200) comprises an excavation assembly (11), in turn comprising: a supporting body (12) having a perimetric edge (16) defining a closed path; a distribution apparatus (18) protruding transversally relative to the perimetric edge (16), movable in a guided manner on the supporting body (12), and for transversally distributing a quantity of hardenable or solidifiable material towards the outside of the perimetric edge (16), so as to be able to lay a plurality of axially superimposed annular layers (s) of said hardenable or solidifiable material defining a tubular structure (T) around said excavation assembly (11); and a motor device (20) for moving the distribution apparatus (18) on the supporting body (12).
