Pile pier composite foundation construction method
The invention discloses a pile-pier composite foundation construction method which comprises the following steps: determining a construction area of field dynamic compaction foundation treatment according to an investigation report, and determining the number of reducing and sinking piles according to the requirement of an upper structure; according to the position of the structural column foundation, the arrangement of dynamic compaction replacement points and the arrangement of anti-sinking piles are determined; according to the arrangement of the dynamic compaction replacement points, construction and detection of a dynamic compaction replacement pier body are conducted; according to the arrangement of the reduced sinking piles, construction and detection of the reduced sinking piles are conducted; and after detection is qualified, structural column foundation construction is carried out. By means of the construction method, the advantages of the dynamic compaction technology, the dynamic compaction replacement technology and the pile reducing and sinking technology can be fully utilized, the dynamic compaction replacement pier body with the high foundation bearing capacity can be rapidly and efficiently formed on the deep filling foundation, and the sinking reducing pile is driven into the dynamic compaction replacement pier body to achieve the purpose of further reducing settlement; and the construction period can be greatly shortened, the cost is reduced, energy conservation and emission reduction are achieved, high social benefits are achieved, and smooth construction of a project is guaranteed.
本发明公开了一种桩墩复合地基工法，包括：根据勘察报告确定场地强夯地基处理的施工区域，根据上部结构要求确定减沉桩的数量；根据结构柱基础位置，确定强夯置换点的布置以及减沉桩的布置；根据强夯置换点的布置，进行强夯置换墩体的施工和检测；根据减沉桩的布置，进行减沉桩的施工和检测；检测合格后进行结构柱基础施工。通过本工法可以充分利用强夯、强夯置换和减沉桩三种工艺的优势，可快速、高效地在深厚填土地基上形成具有较高地基承载力的强夯置换墩体，在强夯置换墩体处打入减沉桩达到进一步减小沉降的目的；直观、可靠并且施工便捷，能大大缩短工期、降低成本，具有节能减排、较高的社会效益，保证工程顺利施工。
