在岩溶极其发育场地进行大直径超长冲孔灌注桩施工的工艺分析

Process Analysis of Construction of Large-Diameter and Ultra-Long Punching Pile in Extremely Developed Karst Site

结合工程实际,对在岩溶极其发育场地条件下进行大直径超长冲孔灌注桩施工的工艺进行了研究。介绍了施工的总体思路、技术方案选型及针对不同溶洞类型的冲孔桩施工工艺,并对工程实施效果进行了总结,以期为类似工程提供参考。

Combined with engineering practice,the process of large-diameter and ultra-long punching pile construction under extremely developed karst site conditions is studied.The general idea of construction,the selection of technical schemes and the construction technology of punching piles with different types of karst caves are introduced,and the implementation effects of these projects are summarized so as to provide a reference for similar projects.
