Abstract:
Prefabricated rings comprising several arcuate sections and an expansion device are installed and frictionally retained in an inclined water conduit so as to dissipate the energy of the water descending therein, thereby slowing it to a velocity at which conduit wear and erosion and other harmful effects by the water in the conduit are acceptable.
