摘要
冲孔灌注桩在岩溶地区施工难度最大,在广西桂林岩溶地区某建筑工程中,根据不同的岩溶类型,采用了相应的岩溶处理方法,在基坑底部有岩石分布的情况下,孔口采取了石方爆破开挖方法。冲孔灌注桩遇溶洞时,针对不同溶洞状态采取了相应的处理措施,保证了冲孔灌注桩的质量和施工安全。
Karst region is the worst condition for construction of punching filling pile. In an architectural project in karst region of Guilin City, relevant karst treatment method is adopted for different karst types. Where there is rock at bottom of foundation pit, explosion excavation method is adopt at mouth of pile hole. When karst cave is encountered during construction of punching filling pile, relevant treatment measures are adopted according to concrete conditions in different karst caves, to successfully guarantee construction quality and safety of punching filling pile.
