为适应水利建设的需要,促进农业生产发展,济南红卫无线电厂与山东省水利科学研究所结合,制成 JD—73型地下水电测仪。这种仪器,适用于内陆平原、滨海及山丘地区地面电测地下水,测试深度可达一千米。通过地面电测得到的数据,可以分析地下水分布的情况,含水砂层的厚度,划分咸淡水的分界面,大大提高机井建设的成井率。
In order to meet the needs of water conservancy construction and promote the development of agricultural production, Jinan Hongwei Radio Factory and Shandong Institute of Water Resources combine to make JD-73 groundwater electrical measuring instrument. This instrument, suitable for inland plains, seaside and hill areas ground electrical groundwater testing depth of up to one kilometer. Based on the data measured by the ground surface survey, we can analyze the distribution of groundwater, the thickness of the water-bearing sand layer, the interface between the fresh and brackish water, and greatly increase the well-formation rate of the well.
