ABSTRACT:
A roller compacted concrete (RCC) dam is formed from inverted T-shape face panels to produce a lower sloped profile and L-shape face panel to produce an upper vertical profile. The face panels have drain openings in their penetrating legs to communicate with drain fill lifts placed against the vertical rise of the face panels. RCC lifts are placed on the penetrating legs to lock the placement of these face panels. The drain openings provide terminal drainage for lift line seepage. The inverted T-shape face panel has both a protruding leg and a penetrating leg projecting into the RCC lift. The protruding leg is provided with a dowel for gripping and alignment that permits raising and lowering of the face panel and is received within a sleeve in the face panel therebelow.
