Abstract:
An assembly of revetments, each revetment being a generally rectangular solid having two longitudinal margins and two transverse margins, having two expansive faces, and having an array of apertures, which extend through said revetment, between the expansive faces, and through which vegetation can grow,wherein each revetment has a grid of embedded reinforcing bars, which include certain of the reinforcing bars extending between certain of the apertures of the array of apertures of said revetment, and which include one of the reinforcing bars extending longitudinally within each of the longitudinal margins of said revetment, wherein each revetment has, on each of the longitudinal and transverse margins of said revetment, at least one rib extending between the expansive faces of said revetment, each revetment having, at each rib, a cable passage extending through said rib and through the longitudinal margin at said rib, the cable passage extending into a near aperture of the array of apertures of said revetment, and wherein the revetments of the assembly are connected to one another, via cables passing through at least some of the cable passages of the connected revetments, so that at least some of the ribs of the connected revetments approximate one another, the approximating ribs being adapted to become crushed, so as to minimize crushing of the connected revetments except at the approximating ribs, if and when the assembly is articulated at the approximating ribs.
