Abstract (en)
[origin: WO2022254325A2] A centring for supporting and consolidating an excavation comprises a plurality of movable structural elements ( 11, 12, 13, 14 ) which are connected to each other in such a manner that the centring can move from a preassembled configuration, at least partially folded before the installation, to a definitive installation configuration, in which the structural elements are locked with respect to each other in a mutual position which generally defines a centring which is at least formed in an arched manner. The structural elements can be locked with structural continuity with respect to each other in a mutual position which generally defines a centring with the closed-geometry profile which comprises the centring which is formed with a closed arch at the bottom by a structural element which acts as a strut or inverted arch.
