Abstract:
Based on previous research results as well as the scour and deposition changes and suspension characteristics of sediment in the pipeline, we identified the non-depositing critical velocity of pipeline transport of sediment considering the real-time changes in sediment concentration and particle size distribution along the pipeline. We compared the measured values with the calculated values of different models, and chose Fei Xiangjun’s model to calculate the non-depositing critical velocity of pipeline transport. Finally, on both theoretical and practical bases, we proposed the pipe diameter and sediment concentration for high-efficiency pipeline transport of sediment in Xiaolangdi Reservoir, which can be a reference for future testing or production practices. We proposed the high-efficiency transport parameters for two different diameters of 0.325m and 0.63m. The two conditions both had the following parameters: a sediment concentration of 620 kg/m3, a median particle size of 0.0512- 0.0629mm, and 0.14mm D90. The transportation velocity can be adjusted between 1.75m/s-2.08m/s and 2.08m/s-2.2m/s. The corresponding largest sand discharge quantity per month was 89500 tons and 347200 tons.
