Abstract:
An underwater building component, comprising:a parallelepiped block having opposing top and bottom surfaces, opposing front and back surfaces and opposing first and second side surfaces; a first, second, third and fourth pair of male and female members normal to said top and bottom surfaces; each of said male and female members comprising; a male protrusion extending normal to said bottom surface; said male protrusion having an annular cross-section having a first geometric center in a plane parallel to said bottom surface; said annular cross-section having a first outer diameter and a second inner diameter defining a hole; a female recess extending normally into said top surface; said female recess having a circular cross-section having a second geometric center in a plane parallel to said top surface; said circular cross-section having a third diameter greater than said first diameter; said first and second geometric centers of said first pair of male and female members aligned along a first axis normal to said top and bottom surfaces adjacent said back and first side surfaces surface of said block; said first and second geometric centers of said second pair of male and female members aligned along a second axis normal to said top and bottom surfaces adjacent said back and second side surfaces of said block; said first and second geometric centers of said third pair of male and female members aligned along a third axis normal to said top and bottom surfaces adjacent said front and first side surfaces of said block; said first and second geometric centers of said fourth pair of male and female members aligned along a second axis normal to said top and bottom surfaces adjacent said front and second side surfaces of said block; first, second, third, and fourth holes extending from said top surface to said bottom surface of said block along said first, second, third and fourth axes, a third cross-section of each of said first, second, third, and fourth holes being less than said first diameter; a turbulence chamber interior to said block between each of said opposing top and bottom surfaces, opposing front and back surfaces and opposing first and second side surfaces; a first flow tube, said first flow tube extending through said block from said front surface of said block into said turbulence chamber; and a second flow tube, said second flow tube extending through said block from said turbulence chamber to said back surface of said block.
