DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to a facility for protecting a harbor or other shores, or for constructing a site on the back of a shore, and for preventing the outflow of sediment on the shore that hits the sea surface.

2. Description of the Related Art Conventionally, as a revetment structure for achieving the above-mentioned object, a stone revetment type revetment structure has been largely constructed using rubble.
