摘要
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。
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 drilling rig in different formations, especially studies the drilling technology of rotary drilling rig in deep soft mud rock, which can accelerate the progress of the bored pile construction, reduce the quality of hidden dangers, and ensure the quality of effective measures.
