BEAVER GUARD FOR DRAINAGE CULVERT

摘要

"BEAVER GUARD FOR DRAINAGE CULVERT" A guard is provided for placement over the upstream opening of a culvert, to bar beavers from entering the culvert and to provide a useful means for dislodging the dam wall which the beavers will build against the guard. The guard comprises a flexible grid consisting of longitudinally extending, spaced apart steel chains, to which are welded a plurality of transversely extending , spaced apart, rigid steel rods. The width of the grid is sufficient to extend across the culvert opening and bear against the culvert side wall; the length of the grid is sufficient so that it extends along the ground surface in front of the culvert opening, so as to be positioned beneath the beaver dam wall. Means are provided at the upper end of the grid, for securing it to the culvert or roadway, so that the grid remains hung over the opening. A long chain extends from the lower end of the grid, which chain is always available to be grasped and which may be attached to a vehicle on the roadway. This provides a means for rolling up the grid and bringing its load of accumulated debris onto the roadway for disposal.
