Study on High-intensity RCC and Aggregate Production Workmanship for Longtan Dam
The paper briefly presents the design features of the aggregate and concrete production systems for Longtan dam. Longtan RCC gravity dam features a dam height of 216.5m, a large quantity of RCC placement and high construction intensity. The aggregate production system with a handling capacity of 2500t/h is the largest one servicing for the hydropower projects in China. It is the first time in Chinese hydropower field to employ a large mobile crushing machine for primary crushing, a large cylinder-type rock washing machine for aggregate washing and a long-distance belt conveyer (4. 0km) for concrete aggregate transportation. The concrete production system has a design capacity of 1080m3/h. The forced batching plants (2 × 6m3) with a production capacity of 110 × 103m3/month for one plant are first employed for RCC production in Chinese hydropower field.
