Novel pipe pile suitable for sand gravel layer and matched pile cap
The invention provides a novel pipe pile suitable for a sand gravel layer, a water guide pipe is arranged in a pile body of the pipe pile, the water guide pipe is arranged in the same direction in the axial direction of the pipe pile, and the two ends of the water guide pipe are communicated with a pile head and a pile tail of the pipe pile; a guiding and discharging channel for discharging water flow and sand gravel is formed in a pipe pile inner cavity in the pipe pile. The water guide pipe is provided with a flaring section on the pile head side of the pipe pile. And a sealing ring is arranged on the inner side of the flaring section. The water guide pipe is provided with a connecting section on the pile tail side of the pipe pile, and the connecting section protrudes out of a pile end plate of the pipe pile so that the pipe pile can be connected with the water guide pipe of the front pipe pile end to end during pile splicing. A certain number of water guide pipes are implanted in the pipe pile, pressure water supplied by the pile cap is ejected out from the pile tail, the sand gravel layer is cut, sand gravel is discharged through the inner cavity of the pipe pile through high-speed water flow, the same effect as hole guiding operation is achieved, construction procedures are not increased, additional professional equipment is not needed, and the construction cost can be greatly reduced.
本发明提供了一种适用于砂砾石层的新型管桩，管桩的桩体内设置有导水管，所述导水管沿管桩轴向方向同向设置，且导水管两端连通管桩的桩头与桩尾；所述管桩内部的管桩内腔形成对水流与砂砾石排出的导引排放通道。所述导水管在管桩的桩头侧设置扩口段。所述扩口段内侧设置有密封圈。所述导水管在管桩的桩尾侧设置连接段，所述连接段突出管桩的桩端板，以便管桩在接桩时与前段管桩的导水管首尾相连。本发明通过在管桩中植入一定数量的导水管，将桩帽供应的压力水从桩尾射出，切割砂砾石层，并由高速水流将砂砾石通过管桩内腔排出，起到与引孔作业相同的作用，但不增加施工工序，也不需要使用额外的专业设备，可大幅降低施工成本。
