中文摘要: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等钻进工艺。根据不同钻探工艺原理论述了施工技术要点,分析了应用效果,创造经济效益。

Construction technology of groundwater monitoring well drilling
Abstract:Groundwater monitoring engineering sites in Henan province are mainly distributed in huanghuai plain, Nanyang basin, luoyang basin and lingsan basin.The types of groundwater monitoring 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 cycle, positive cycle rotary drilling, impact drilling and air potential hole hammer are adopted.The application effect is analyzed.The project has created benefits.
