摘要
结合某220kV户内变电站冲孔灌注桩的岩溶地基处理,论述了冲孔灌注桩根据溶洞深度、层次和填充物的类型采取不同的溶洞处理施工方法,并提出防止漏浆、塌孔、卡钻、斜钻等技术措施,施工效果检验良好。
Based on punch filling-pile for a 220kV indoor substation at karst foudation,the paper mainly introduces different construction methods for karst handling on the basis of cavern depth,layer grade,filling matter etc,puts forwards technical measures to prevent grout-leakage,hole collapse,drilling-tool jamming and deviation etc,which leads to good effect proven by construction.
