采用冲孔振动密实法进行水泥土挤密桩作业的施工方法
摘要：
本发明涉及一种采用冲孔振动密实法进行水泥土挤密桩作业的施工方法，采用一种挤密桩钻头，在成孔后直接利用钻头顶部的下料口进行填料，同时钻头本体在分段填料过程中间隔停振，从而实现边开孔、边下料、边密实的连贯性施工作业。本发明在不拆除原有轨道的条件下，实现成孔、投料、振捣一体化施工，缩短了整体施工周期，从而提高施工效率。
摘要（英）：

The invention relates to a construction method for operating a cement-soil compaction pile by a punching vibration compaction method. A kind of compaction pile drill is adopted, a filler is directly filled in a blanking opening on the top of the drill after holes are formed, and a drill body periodically stops vibrating in the sectional filling process, so that hole formation, blanking and compaction coherent construction operation is realized. Under the condition that the original track is not detached, hole formation, feeding and vibration integrated construction is realized, and the whole construction period is shortened, so that construction efficiency is improved.
