Special-shaped foundation pit PC construction method pile construction method suitable for rapid flow condition
The invention relates to a special-shaped foundation pit PC construction method pile construction method suitable for the rapid flow condition. According to the water flow direction, pipe piles in the same direction as the water flow direction are piled preferentially; after construction of the tubular piles on the two sides is completed, Larsen steel sheet piles are hit in gaps of the existing tubular piles; after water flow same-direction construction is completed, transverse pile construction is conducted, downstream pipe piles are piled preferentially, and then upstream pipe piles are piled in sequence; and all the tubular piles are constructed, and then Larsen steel sheet piles are sequentially constructed from the downstream to the upstream. The construction method has the beneficial effects that the influence of water flow on the perpendicularity of the pile body is weakened by changing the construction sequence of the PC construction method pile, and the construction precision can be effectively improved; and similar piles are continuously inserted and driven, so that the equipment leasing cost is saved.
本发明涉及一种适用于急流情况下异形基坑PC工法桩施工方法，根据水流方向优先施打与水流方向同方向的管桩；待两侧管桩施工完成，将拉森钢板桩施打在现有管桩间隙中；水流同向施工完毕后，进行横向桩施工，优先施打下游管桩，随后依次施打上游管桩；将所有管桩施工完毕，随后同样由下游向上游依次施工拉森钢板桩。本发明的有益效果是：本发明通过改变PC工法桩施工顺序，削弱水流对桩身垂直度的影响，可有效提高施工精度；并且同类桩连续插打，节省设备租赁费用。
