进入21世纪以来,国内的交通事业获得了较快速的发展。在深厚软土地基上进行施工时,桩板结构的强度高并且刚度,还有着稳定性好以及沉降小的优点。目前跨浅埋地铁深厚软土路基的施工,多使用桩板结构的施工技术。本文结合笔者自身经验,对实际施工过程中的难点进行分析,并进一步探讨全套管钻孔桩施工技术以及桩板结构钻孔桩桩底注浆加固等技术。
Since entering the 21st century, the domestic transport industry has achieved rapid development. In the deep construction of soft soil foundation, pile structure of high strength and stiffness, but also has good stability and the advantages of small settlement. At present, the construction of deep soft soil subgrade across shallow-buried subway uses construction technology of pile-plate structure. Based on the author’s own experience, this article analyzes the difficulties in the actual construction process and further discusses the construction technology of the full-pipe drilling pile and the grouting reinforcement of the bottom of the pile-structure drilling pile.
