Rigid pile composite foundation with expansion head and construction method of rigid pile composite foundation
The invention discloses a rigid pile composite foundation with an expanded head and a construction method thereof.The rigid pile composite foundation comprises a flexible pad, an annular pipe type bearing part, a circular bearing part, a curing layer with a continuous surface layer and rigid piles arranged at intervals, one end of the annular pipe type bearing part is connected with the rigid piles through the flexible pad, and the other end of the annular pipe type bearing part is plugged by the circular bearing part; the ratio of the diameter of the annular pipe type bearing piece to the diameter of the rigid pile is 3-6, the annular pipe type bearing piece and the flexible pad are both located on the curing layer, the circular bearing piece is flush with the curing layer, a soil filling layer is arranged above the curing layer, the annular pipe type bearing piece comprises an annular pipe and at least three spacers, one ends of the spacers are connected with the annular pipe, and the other ends of the spacers are connected with the rigid pile. And the other ends of the connecting rods intersect at the center of the ring pipe and divide the inner space of the ring pipe into at least three parts. According to the composite foundation, the pile structure is optimized to increase the pile distance, coordinate settlement of rigid piles and soil between the piles and reduce the cost, and when the composite foundation is applied to road soft foundation treatment, pile cap disengaging can be effectively avoided.
本发明公开了一种带扩大头的刚性桩复合地基及其施工方法，包括柔性垫、环管型承载件、圆型承载件、表层连续的固化层以及间隔设置的刚性桩，环管型承载件的一端与刚性桩之间通过柔性垫连接，圆型承载件封堵环管型承载件的另一端，环管型承载件的直径与刚性桩的直径之间的比值在3～6，环管型承载件以及柔性垫均处于固化层，圆型承载件持平固化层，固化层上方设置有填土层，环管型承载件包括环管和至少三片隔片，多片隔片的一端连接环管，另一端相交于环管的中心且将环管的内部空间分隔成至少三份。本发明的复合地基，通过对桩结构进行优化以增大桩间距、协调刚性桩与桩间土沉降、降低成本，应用于道路软基处理时，能够有效避免出现桩帽脱空。
