Pile sinking construction method and construction structure of prestressed pipe pile
The invention discloses a pile sinking construction method and construction structure of a prestressed pipe pile, and the pile sinking construction method comprises the following steps: sinking the prestressed pipe pile to a first depth smaller than a designed pile sinking depth in a foundation by adopting a mode of synchronous construction of drilling of a drilling bit and pile sinking; and a bottom reaming hole section with the depth larger than the designed pile sinking depth is drilled below the prestressed pipe pile sinking into the first depth through a bottom reaming drill bit, the bottom reaming hole section is filled with concrete, and then the prestressed pipe pile is sunk to the designed pile sinking depth. The construction structure is obtained by adopting the pile sinking construction method. The method has the advantages of high construction quality, high construction efficiency, low cost, simplicity and convenience in operation, high tubular pile bearing capacity and the like.
本发明公开了一种预应力管桩的沉桩施工方法及施工结构，沉桩施工方法包括采用钻进钻头钻孔配合沉桩同步施工的方式将预应力管桩沉桩至地基中小于设计沉桩深度的第一深度，采用扩底钻头在沉入第一深度的预应力管桩的下方钻出一段深度大于设计沉桩深度的扩底孔段，向扩底孔段中填充混凝土，然后将预应力管桩沉桩至设计沉桩深度的步骤。施工结构为采用该沉桩施工方法施工得到的施工结构。本发明具有施工质量高、施工效率高、成本低、操作简便、管桩承载能力大等优点。
