AN IMPACT ABSORBING UNIT OF A ROCKFALL PROTECTION GALLERY AND THE RELATIVE ROCKFALL PROTECTION GALLERY
An impact absorbing unit (1) of a rockfall protection gallery (G), wherein: it comprises a plurality of columns (2) which are arranged flanked to one another; each column (2a) of the plurality of columns (2) comprises: a plurality of collapsible tubular elements (3); a plurality of connecting elements (4) for connecting the collapsible tubular elements to one another; each collapsible tubular element (3a) of the plurality of collapsible tubular elements (3) comprises an end edge (5) and has a length (L) and a transversal section (S) which are inter-related in order to determine a folding process along the relative extension axis (X) when the collapsible tubular element (3a) is subjected to an axial force having an intensity that is at least equal to a critical force value; each connecting element (4a) of the plurality of connecting elements (4) comprises a first face (6) and a second face (7), opposite the first face (6), and is fixed to two collapsible tubular elements (3a, 3b) of a same column (2a) of the plurality of columns (2), which are consecutive to one another. The impact absorbing unit (1) is configured in such a way that, during use, at least a part of the collapsible tubular elements of the plurality of collapsible tubular elements (3) deforms in an irreversible way, by effect of the compression determined by an axial force exerted by a mass (M) falling on the rockfall protection gallery (G).
