摘要
基于云南昆明大板桥镇岩溶极发育的特殊地质条件,开展旋挖灌注桩施工技术研究.通过旋挖钻机施工参数的研究,提出了钻头适应性分析和钻进参数分析的关键内容,确保施工的高效性和安全性.结合双钢护筒处理土岩交界面坍孔和地质钻孔注浆填充预处理溶洞两种施工技术,提出了解决岩溶地区施工问题的具体措施.
Abstract
Based on the special geological conditions of extremely developed karst in Dabanqiao Town,Kunming,Yunnan,research on the construction technology of rotary bored pile was conducted.The key contents of drill bit adaptability and drilling parameter analysis were proposed by studying the construction parameters of rotary drilling rigs to ensure the efficiency and safety of construction.Specific measures have been proposed to solve construction problems in karst areas by combining two construction techniques of using double steel casing to treat soil rock interface collapse holes and geological drilling grouting to fill pretreated karst caves.
