ABSTRACT:
A cylindrical structure suitable for use as a drainage culvert made from the side walls of discarded motor vehicle tire casings. The side wall sections are stacked and bonded in axial alignment so that the concave face of each of the next adjacent side wall faces the convex face of the next adjacent side wall. One end face of the structure is thus concave and the other end face is convex so that the cylindrical structure can be placed in close alignment with the concave end face of one cylinder in close abutting contact with the convex end face of a second cylinder. Wide kerfs are cut in selected side walls between the outer rim of the side wall and the inner rim so that the selected side walls can expand or contract during banding to provide a rather uniform opening in the cylinder. The kerf also allow the cylinders to weep when water is being conducted therethrough.
