浅谈旋挖钻机在泥岩地质条件下施工钻孔灌注桩的体会

摘要

In this article, the author bases on the geological conditions of the project, points out the drilling technology and control points of 260-YTR rotary dril ing rig in different for-mations, especial y studies the dril ing technology of rotary dr-il ing rig in deep soft mud rock, which can accelerate the pro-gress of the bored pile construction, reduce the quality of hidd-en dangers, and ensure the quality of effective measures.%　　根据本项目的地质条件，指出 YTR 260型旋挖钻机在不同地层中的钻进工艺及控制要点。特别对旋挖钻机在深埋软质泥岩层的钻进工艺进行了研究，它是加快钻孔灌注桩施工进度、减少质量隐患，保证质量的有效措施。
