Quadripod
The quadripode is a molded concrete part that is used to build breakwaters for coastal protection . Unlike those of a tetrapod , its four “arms” are not aligned with the corners of an imaginary tetrahedron , but three of the arms form a flat star, on the center of which the fourth arm rests vertically.
