运用泵船取水方式解决尊村泵站渠首水源脱流问题的探讨

提出了作者对黄河小北干流段河势的认识,从时间上看摆动是必然的,着流是相对的;从空间上看,黄河主流摆动不是小北干流段特有的现象;黄河小北干流段主流摆动的主要因素是多泥沙特征,河床的宽浅特征及液化砂层的地质特性。介绍了以往解决脱流问题的经验教训,论证了泵船取水方式的可行性,并对其参数诸如单船规模、稳定性、航行动力、空载吃水深度、泵船空载重量、工作吃水深度、平衡水仓容量、压载水仓容量、船体尺寸等的设计进行了考虑

On Pump ship Diversion in Zuncun Lift Station During River Flow Separating from Its Intake

The author has first given his knowledge on the river situation of Xiaobeigan main stream of the Yellow River,then has introduced the previous experiences and lessons of solving diversion problem for Zuncun lift station when the Yellow River flow separates from the intake of the lift station,finally has illustrated the feasibility of the water diversion scheme by pump ship,and has put his consideration on some issues relating to the parameters of pump ship such as scale of the single ship,stability,power,draft of empty weight,self weight of the ship,draft at working time,size of the ship body,and so on.
