Bag expanded-base rigid-flexible combined pile and construction method thereof
The invention relates to a bag bottom expanding rigid-flexible combined pile which comprises a pipe pile, one end of the pipe pile in the length direction is wrapped with a bag, a grouting hole penetrating through the pipe pile is formed in the bag wrapping area of the pipe pile, the grouting hole is communicated with the interior of the bag and the interior of the pipe pile, the bag is wound on the pipe pile, a hoop is arranged on the bag in a sleeving mode, and the hoop is connected with the pipe pile in a sleeving mode. The hoop is arranged on the pipe pile in a sliding mode, and the hoop is separated from the bag through sliding. The composite pile has the effect of reducing the influence of the hoop on the stability of the composite pile.
本申请涉及一种囊袋扩底刚柔组合桩，包括管桩，所述管桩长度方向一端外包有囊袋，管桩包覆囊袋区域开设有贯穿管桩的灌浆孔，所述灌浆孔连通囊袋内部和管桩内部，所述囊袋收卷在管桩上，所述囊袋外套上有环箍，所述环箍滑移设置在管桩上，环箍通过滑移脱离囊袋。本申请具有降低环箍对组合桩稳固性影响的效果。
