摘　　要：针对我国地下水监测现状和存在的技术问题,开展了对50 mm巢式监测井PVC-U井管的建井生产试验并组织实施了一眼五层巢式地下水监测井。介绍了该井整体的结构设计、PVC-U井管、新型止水粘土球、扶正器和成井关键工艺以及最终取得的成果。可为以后的多层巢式地下水监测井建设提供参考,并为我国地下水多层监测井技术的发展提供支撑。According to the present situation and existing technical problems of groundwater monitoring in China, the well building test for 050mm PVC - U tribe for nested monitoring well was carried out. Design and construction were implemen- ted for a five-layer nested monitoring well. The paper introduces the overall structural design, PVC - U well pipe, new type of clay balls for water stop, centralizer, key technology of well completion and the final results of the monitoring well. This work can offer a reference for the construction of multi-layer nested monitoring wells and provide support to the development of groundwater multi-layer monitoring well technology in China.
