4、，冲洗效率直接关系到沉沙池的布置，以及引渠设计流量。当沉沙池为泵站供水时，由于冲洗效率受冲洗流量制约，冲洗流量又影响到泵站装机容量、机组选型和布置，以及耗水费用等。在处理高含沙量水流的沉沙池设计中，上述问题十分突出，故研究冲洗效率是工程设计中的一个现实问题。/SPANPclass=MsoNormalTEXT-ALIGN:leftalign=leftSPANFONT-SIZE:12pt;FONT-FAMILY:宋体 泄空冲洗是 LABELclass=lbonclick=g(水利);水利/LABEL 工程定期冲洗式沉沙池的一种特殊冲洗方式。一般情况下，沉沙池停止淤积运行之初，池内尚存有一定数量的水
