ABSTRACT:
An essentially equilateral tetrahedron having essentially four equilateral sides, each of which, in turn, an equilateral triangle is disclosed. The reef module may be any size, but for practical purposes in excess of one foot on an edge, and not necessarily exceeding six feet on an edge by a significant amount. The medium primarily employed to hold the implanted tire chips in place is cement, or its equivalent. Desirably a hydraulic cement is employed because of its high strength capability as well as durability. A related aspect of the present invention looks to the provision of lifting means on each such equilateral tetrahedron to permit the same, with relatively crude equipment, to be moved about in a factory sight, on to trucks, on to barges, and off barge to its ultimate resting place at the bottom of the sea. In connection with the method of forming the modules, an open-ended three sided mold is formed in the shape of a tetrahedron with the open end up. It is filled with approximately half the weight of tire chips that the mold is capable of holding with the resulting void being concrete. The proportions are not necessarily critical to the invention but exemplary of the mix and the result which can be obtained, namely, with an exemplary tetrahedron three feet on each edge, approximately five and three eights tires in the form of tire chips can be encased and permanently dispatched to the bottom of the sea, ocean, bay, lake or any other body of water.
