| 中文摘要:地下水监测井是进行地下水监测的公益性、永久性基础设施，其施工质量直接决定后期的运行效果，钻探成孔是施工中的重要环节。河南省范围内地下水监测工程站点主要分布在黄淮平原、南阳盆地、洛阳盆地及灵三盆地，监测地下水的类型以孔隙水为主，其次为基岩裂隙水和岩溶水。钻探施工根据监测井性质和地质条件不同，分别采用泵吸反循环、正循环回转钻进、冲击钻进及空气潜孔锤钻进等。根据不同钻探工艺原理论述了施工技术要点，对比分析了各工艺的特点及应用效果，总结的施工经验可供类似工程参考。 |

| Abstract:Groundwater monitoring wells are public welfare permanent infrastructure for groundwater monitoring, and construction quality directly determines its performance in the later period. Groundwater monitoring stations in Henan are mainly distributed in Huanghuai Plain, Nanyang Basin, Luoyang Basin, and Lingsan Basin. The types of groundwater to be monitored are mainly pore water, followed by bedrock fissure water and karst water. According to the characteristics and geological conditions of the monitoring wells, drilling processes such as pump suction reverse circulation, direct rotary drilling, percussive drilling, and air down-hole-hammer drilling are adopted. The article analyzes the characteristics and field performance of each process, which can be used as reference for similar projects. |
