NON-ABRASIVE, ARTICULATED SEABED MAT

摘要

Concrete blocks (1) with an open cell structure (6) extending throughout the entirety of the block are assembled in substantially parallel columns and ro ws to form a mat structure capable of articulating over underwater structures. The blocks are assembled by flexible cables that pass through the center of each block through perpendicular apertures (7a,7b), which are located on different horizontal planes to prevent intersection of the cables. A removab le abrasive resistant pad (9) is placed on one surface of the blocks to prevent the concrete block from causing damage to the structure. The pad is comprise d of a solid base with an opening matching the opening on the block. It also h as a plurality of upwardly extending posts (11) which serve as a contact point between the pad and the underwater structure and at least one self-locking dowel (12) extending downward, which are inserted into dowel holes (13) on o ne surface of the block, after the concrete has hardened. The entire pad is one homogenous material. This size of the mat is capable of being dynamically modified at the site of installation to accommodate various situations.
