Pile-column integrated structure for cover-excavation top-down construction method and construction process
The invention belongs to the technical field of pile body structures and construction, and discloses a pile-column integrated construction structure and a construction technology.The pile-column integrated construction structure comprises a concrete pile and a steel pipe concrete column, the steel pipe concrete column is located on the upper portion of the concrete pile, and the top end of the steel pipe column can be connected with a tool column through a flange; the construction technology of the structure comprises the following steps that firstly, pile positioning is conducted, then a pile casing is buried, a pile hole is drilled and cleaned, then a reinforcement cage is installed, and after secondary hole cleaning is conducted and reaches the standard, concrete is poured to form a concrete pile; and then the steel pipe column spliced with the tool column is vertically inserted into the just-poured concrete pile and reaches the designed elevation, gravel backfilling can be conducted on the periphery of the steel pipe column, after concrete is finally set, equipment is dismantled, residual mud is pumped dry, the tool section is dismantled, and finally the empty hole is filled back. The steel pipe column center deviation and perpendicularity can be accurately controlled, steel at the position above the top of the steel pipe column can be saved, and labor and the construction period are reduced.
本发明属于桩体结构及施工技术领域，本发明公开了一种桩柱一体施式结构及施工工艺，桩柱一体式结构包括混凝土桩和钢管混凝土柱，钢管混凝土柱位于混凝土桩上部，钢管柱的顶端能够通过法兰能够连接工具柱，该结构的施工工艺包括如下步骤，首先进行桩定位，然后埋设护筒、钻设桩孔并进行清孔，接着进行钢筋笼安装，并进行二次清孔达标后浇筑混凝土形成混凝土桩，紧接着将拼接好工具柱的钢管柱垂直插入至刚浇筑的混凝土桩内并到达设计标高，即可对钢管柱四周进行砂石回填，混凝土终凝后拆除设备、抽干剩余泥浆，拆除工具节，最后回填空孔，本发明对于钢管柱柱心偏差及垂直度都可进行精确控制，其次可节省钢管柱顶以上位置钢材，减少人工及施工工期。
