水文地质勘探分层抽水取样装置的优化研究

Optimization Study on Layered Pumping Sampling Device for Hydrogeological Exploration

针对分层抽水装置施工烦琐的问题,研制了一种新型定向分层抽水装置,主要对抽水装置、电缆密封装置和隔水装置等进行了改进,从而实现了对分层抽水取样试验装置的优化,确保抽水试验全过程安全可靠、便捷高效。并通过现场试验确定了第1~2含水层硝酸盐氮指标超限,表明该装置能满足水文地质勘探单井精准分层取样的工作要求。

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,reliability,convenience,and efficiency of the entire pumping test process.And through on-site testing,it is determined that the nitrate nitrogen index of the 1st and 2nd aquifers exceed the limit,indicating that the device can meet the requirements of precise stratified sampling for hydrogeological exploration of single wells.
