摘要
A revetment unit for protecting shoreline or waterway embankments from eron comprising a generally L-shaped web having first and second arm portions converging at an apex and forming a 90° right angle. Each of the first and second arm portions terminate at end portions. Identical cylinder members are associated with the web and extend above and below the plane of the web. The cylinder members have a height substantially less than their width and a single cylinder member is positioned at each of the end portions and at the apex. The web has a width slightly less than the diameter of the cylinder members yet greater than the radius of the cylinder members. The end portion cylinders are equally spaced from the apex cylinder a distance between about 0.10 to about 0.25 of the diameter of the cylinders. The units are configured so that when at least five of the units are assembled in an interacted relation, at least three of the five will face in a direction opposite to that of the remaining two of the at least five units.
