| Abstract: |
| With high cement sand content and fine particle size in the Yellow River, laying inclined pipe is considered to be one of the effective ways to solve the problems of large construction area and high construction cost in the traditional sand sedimentation tank. However, the optimal layout of inclined pipe in the sedimentation tank is still unclear. In this paper, the sediment distribution in the upper, middle and lower reaches of the Yellow River and three forms of the Yellow River, and studied the sediment deposition characteristics under different inclined pipe forms. The results show that the large particle sediment has settled before entering the inclined tube, the inclined tube mainly deposits the fine particle sediment (d <75 μ m), the sediment content of the outlet is 0.342~1.356kg/m3, the sediment deposition rate is 41.73%~70.04%, the sediment content of the outlet is 0~0.019kg/m3, and the sediment deposition rate of the inclined tube is 90.18%~100%; The three kinds of inclined pipe arrangement treat the Yellow River sediment significantly (P 0.05), and the V-shaped inclined pipe layout is better than the conventional inclined pipe layout, and the inclination is 60° and 45°; the outlet sediment content and component content of different Yellow River water is Su
