Soft foundation treatment structure for airport and construction method thereof

TAN WENJIE / HU YI / WU QIMENG / BIAN LEI

The invention discloses a soft foundation treatment structure for an airport and a construction method of the soft foundation treatment structure, and belongs to the technical field of airport soft foundation treatment. The soft foundation treatment structure comprises a reinforcement cage, the peripheral wall of the reinforcement cage is at least connected with two connecting rods, and the connecting rods are connected with positioning mechanisms; the positioning mechanism comprises a stand column and a connecting block arranged on the stand column in a sleeving mode, and the connecting block is connected with the connecting rod through a fastener. The reinforcement cage is limited through the positioning mechanism, so that when the reinforcement cage is impacted by concrete, good stability can be kept, and the perpendicularity of the post-pouring treatment pile is guaranteed; and supporting force can be continuously provided when the foundation is used as a composite foundation for bearing subsequently.

本发明公开了一种机场用软地基处理结构及其施工方法，属于机场软地基处理技术领域。本发明的软地基处理结构包括钢筋笼，所述钢筋笼的外周壁至少连接有两个连接杆，所述的连接杆连接有定位机构；所述的定位机构包括立柱以及套设在该立柱上的连接块，该连接块与连接杆之间通过紧固件进行连接。本发明通过定位机构对钢筋笼进行限位，不仅可使得钢筋笼在受到混凝土冲击时，能够保持较好的稳定性，从而保证浇筑后处理桩的垂直度；还可以在后续作为复合地基进行承载时，持续提供支撑力。
