Abstract
Abstract The block (1) has a cambered front (2) radiused to tapering side walls (3a,3b). The side walls (3a,3b) have, in the portion radiused to the front (2), mutually opposite insertion-coupling members (5) and seats (6) for accommodating the insertion-coupling members (5) of an adjacent block (1). The block (1) furthermore has, at an upper part thereof, an abutment (7) for engagement with a supporting element defined on a lower part at the front (2) of an adjacent block (1).
