<p>An artificial reef is designed for replacing and protecting naturally occurring reef structures. The artificial reef comprises multiple vertically stacked concrete panels (1) separated by spacing blocks (2, 3). The panels and spacing blocks are fixed together by reinforcement rods (7) which are held in place by epoxy grout (14). The concrete panels of the reef have a flat upper surface and an undersurface of a waffled configuration and are stacked in a manner to permit substantially all of the surface area to be exposed to the estuarine environment. The waffled configuration provides a complex shape to the reef and encourages both calm and turbulent water flow within the reef so as to avoid areas of water stagnation. The modular nature of the panels permits wide flexibility in size and shape of the reef. The use of concrete provides an inert, non-corroding composition of the reef and permits on-shore construction of the reef. Lifting rings (4) embedded in the top surface of the artificial reef permit deployment by a crane.</p> |
