摘要
结合一个工程实例,通过分析前期失败教训,选用自行设计的钻头,采用常规的冲击钻工艺,快速有效地处理旋挖钻埋钻事故,而且费用低廉。
Combined with an engineering example,by analyzing the lessons of previous failures,self-designed bits and conventional percussive drilling technology are selected to deal with the burial accident of rotary drilling quickly and effectively,and the cost is low.
