Abstract

A structural modular element (10) for supporting rock excavations has a curved shape with a U-like cross-section and flanges (11,12) directed toward the centre of curvature. A plurality of elements (10) are assemblable to each other, in order to provide a type of lining suitable to any particular geological situation, by means of slots (15) provided both on the flanges (11,12) and on the stiffing plates (14) of the elements (10).
