本专栏第1讲介绍了旋挖钻机在泥岩地层中钻进的工法知识,内容侧重于如何提高钻进效率、减少钻齿磨损这两方面。很多行业内朋友看到文章后和三一工法研究院取得了联系,纷纷表示采用文章中介绍的工法进行施工收到了很好的效果,但同时也向我们提出了另一个问题:钻机在泥岩地质施工时常常会出现钻具打滑、不进齿的现象,大大降低了钻机的工作效率,让人很着急,希望我们能专门讲解如何处理旋挖钻机打滑的工法。应此要求,这一期我们就旋挖钻机施工时钻具打滑的现象做专门的分析,介绍三一工法研究院在这类问题上的
Box 1 of this column introduces the working method knowledge of rotary drilling rigs in mudstone formation, focusing on how to improve drilling efficiency and reduce wear of drilling teeth. After seeing articles, many friends in the industry got in touch with the Sanyi Research Institute of Law and said that they have received very good results in using the construction method introduced in the article, but at the same time, they also raised another question for us: drilling rigs in mudstone geology During construction, there often appears the phenomenon of slipping and not drilling teeth, greatly reducing the working efficiency of drilling rig and making people anxious. We hope we can explain how to deal with the slip method of rotary drilling rig. In response to this request, we made a special analysis of the phenomena of slippage of drilling tools during the drilling rig construction in this issue, and introduced the Sany Law Research Institute on such issues
