摘要
通过广西河池市九圩镇水厂大直径供水井的施工实例,详细介绍了岩溶复杂地层大直径、大涌水钻孔的空气潜孔锤钻进技术、扩孔技术、钻孔护壁技术及施工工艺。
By the construction ease of a large diameter water supply well in a water plant of Guangxi, the paper detailed air downhole hammer drilling, hole reaming, borehole wall protection and construction technology in borehole with large diameter and serious water flow in complicated karst formation.
