| 中文摘要:多通道地下水监测技术能够大幅度降低地下水监测成本。多通道监测井成井井管是采用HDPE材质挤出若干通道的连续管材，在每个通道指定位置加工窗口，对应相应的地下水监测层位，并设计合理的填砾止水厚度。根据多通道地下水监测井特点，研制新型的止水材料。采用该种地下水监测技术，先后在北京、天津、甘肃等地建立了地下水监测示范工程。与传统地下水监测技术相比，节约了占地面积、减少了钻探进尺，与国外CMT地下水监测技术对比，适用范围更广，建井成本更低。 |

| Abstract:The multilayer groundwater monitoring can greatly reduce the cost of groundwater monitoring. The well pipe is a whole pipe made of HDPE material with several channels by extrusion, monitoring windows are processed at special position on each channel for corresponding groundwater monitoring layers and the rational thickness of gravel fill for sealing is designed. Based on the characteristics of multilayer groundwater monitoring well, new sealing material is developed. By the use of this groundwater monitoring technology, the demonstration projects of groundwater monitoring are successively set in Beijing, Tianjin and Gansu. By this new technology, construction area can be saved and drilling work reduced ompared with conventional technology; and compared with foreign technology, it has wider application scope with lower cost. |
