High fill area end bearing pile foundation construction method
The invention relates to the technical field of civil engineering, in particular to a high fill area end bearing pile foundation construction method which comprises the steps of construction preparation, surface layer backfill soil excavation, first layer dynamic compaction foundation layer construction, soil paving and rolling compaction, second layer dynamic compaction foundation layer construction, compaction backfill foundation treatment, bearing capacity detection, rigid pile paying-off positioning and drilling. According to the construction method for the end bearing pile foundation of the high fill area, the negative friction resistance of backfill soil on the pile side is reduced, it is guaranteed that the pile and the soil are jointly stressed, and the construction efficiency of the end bearing pile foundation of the high fill area is improved. After the foundation which is not suitable for building a high-rise building originally is treated, the requirement for the bearing capacity of the designed foundation can be met, the land utilization rate is greatly increased, the land cost is saved, and compared with an existing replacement filling method for compacting the foundation, construction is fast, economical efficiency is good, and social and economic benefits are remarkable.
本发明涉及土建工程技术领域，尤其涉及高填方区端承桩基础施工方法，包括施工准备、表层回填土开挖、第一层强夯地基层施工、铺土碾压、第二层强夯地基层施工、压实回填地基处理、承载力检测、刚性桩放线定位、钻孔，孔壁防塌孔工艺处理、清理孔底、下钢筋笼、混凝土灌注、检测桩身完整性和清理土层、截桩头至设计标高，采用本技术方案的高填方区端承桩基础施工方法，减小了桩侧回填土的负摩阻力，保证桩土共同受力，将原来不适宜修建高层建筑的地基处理后，可达到设计地基承载力要求，大大提高土地利用率，节约土地成本，相对目前换填法压实处理地基相比，施工快，经济性好，社会经济效益显著。
