A concrete rhombic dam is provided to prevent the outer surfaces of concrete sleets from being damaged due to floating timbers or rocks by covering the whole outer surface of the concrete sleet with a sleet cover. A concrete rhombic dam comprises a timber blocking unit(10) and a rock blocking unit(20), and dam shoulders(30). The timber blocking unit is constructed on the rock blocking unit. The timber blocking unit includes concrete sleets(11) and screen bars(12), and a sleet reinforcing cover(15). The screen bar is attached to the front part of the concrete sleet. The dam shoulders are built at two ends of the rock blocking unit. The sleet reinforcing cover surrounds the whole outer surface of the concrete sleet. |
