目前,国内泥沙处理方面尚无统一标准可循,需依据各站具体条件而定。夹马口、尊村、小樊是山西省三大引黄泵站。三站干渠渠道淤积物大部分是0.05mm以上粗沙。夹马口站含沙量与单机流量相关式为Q=0.7976—0.0012S,相关系数为-0.8。泵站装置效率随含沙量的增大而减小。综合研究含沙量与出水流量及装置效率关系及渠道挟沙能力要求后,确认三大泵站的泥沙处理标准应为:对粒径大于0.05mm的粗沙应予以处理,汛期出池含沙量应小于15kg/m3,非汛期出池含沙量应小于5kg/m3。
At present, there is no uniform standard for handling sediment in China, and it depends on the specific conditions of each station. Folder jaws, respect village, small fan is Shanxi Province, the three Diversion Yellow River pumping station. Most of the sediments of the three main trunk channels are 0.05mm thick coarse sand. The correlation between the sediment concentration at the mouth of the station and the stand-alone flow rate is Q = 0.7976-0.0012S and the correlation coefficient is -0.8. Pumping station efficiency decreases with increasing sediment concentration. Comprehensive study of sediment concentration and effluent flow and device efficiency and channel sediment carrying capacity requirements, confirm the three major pumping station sediment treatment standards should be: the particle size greater than 0.05mm of coarse sand should be treated, the flood pool Sediment should be less than 15kg / m3, non-flood season sediment concentration should be less than 5kg / m3.
