【摘要】 面对黄河断流的实际,为了合理开发利用黄河滩地和河床下蕴藏的较丰富的浅层淡水资源,对利用辐射井技术开发黄河滩地浅层地下水进行了试验研究。在介绍试验地地质情况的基础上,详细阐述了在黄河下游滩地极细粉沙含水层中打辐射井的成井技术、试验井的井深选择、水平集水管的布置、试验井的水质和水量等。更多还原

【Abstract】 Facing the problem of discontinuous flow in the lower reach of Yellow River, in order to develop reasonably the quite abundant resources of shallow fresh water on the over-bank flood plain and the river bed, experimental researches on the developing shallow groundwater on the over-bank flood plain of Yellow River by using redial collector well techniques are conducted. On the basis of introducing geological conditions, the techniques of drilling redial collector well in the fine silt sand aquifer on the over-bank flood plain at the lower reach of Yellow River are expounded in detail. The selections of the depth of the experiment wells, the layout of the horizontal collector pipes, the water quality and quantity of the experiment well are also expatiated in this paper.更多还原
