辐射井技术在宁夏应用的探索与实践

辐射井是开发浅层地下水的理想井型，引进其施工技术在宁夏建设抗旱机井中采用．阐述辐射井开发浅层地下水的设计方法，如竖井结构、井深，水平管及涌水量计算等．并对成井技术、试验井的水量和水质进行了探讨．提出辐射井可在宁夏地区农田灌溉排水、井渠结合、井灌井排、旱涝碱综合治理、城镇及工矿企业供水、工民建基坑降水等方面应用．

Exploration and practice of radial collector well technique applied in Ningxia

Radial collector well is an ideal type of shallow groundwater exploitation. Radial collector well construction technology can be well adopted to build anti drought motor pumped well in Ningxia. The design methods of shallow groundwater development using radial collector well technique,such as the structure of silo designs of well depth,horizontal radial collector,and calculation of discharge etc.,were expatiated. The technique of well construction,water quantity and quality of the pilot well were also discussed. Radial collector well can be used in many regions in Ningxia,such as irrigation and drainage,improvement of saline land,water supply in city or town,and groundwater in excavation of civil construction building.
