Optimization Study on Layered Pumping Sampling Device for Hydrogeological Exploration
A new type of directional layered pumping device is developed to address the tedious construction of layered pumping devices.Improvements are made to the pumping device,cable sealing device,and water blocking device,thereby optimizing the layered pumping sampling test device and ensuring the safety,relia-bility,convenience,and efficiency of the entire pumping test process.And through on-site testing,it is de-termined that the nitrate nitrogen index of the 1st and 2nd aquifers exceed the limit,indicating that the de-vice can meet the requirements of precise stratified sampling for hydrogeological exploration of single wells.
