Post-inserted stand column cast-in-place pile construction method and cast-in-place pile constructed by
The invention discloses a post-inserted stand column cast-in-place pile construction method and a cast-in-place pile constructed by the same. The cast-in-place pile construction method comprises the steps that drilling operation is carried out at the position of a pile foundation, and a pile foundation cast-in-place hole (1) is obtained through drilling; a steel reinforcement cage (2) prepared in advance is placed in a pile foundation pouring hole; concrete is poured into the pile foundation pouring hole; a steel pipe stand column (3) prepared in advance is inserted into the concrete in the pile foundation pouring hole; a head expanding hole section (11) is arranged at an upper opening of a pile foundation pouring hole obtained through drilling operation; the upper end part of the reinforcement cage is provided with an external expansion head part (21); and after the reinforcement cage is placed in the pile foundation pouring hole, the outer expansion head of the reinforcement cage is located in the head expansion hole section of the pile foundation pouring hole. The cast-in-place pile is constructed by adopting the cast-in-place pile construction method. According to the cast-in-place pile construction method and the cast-in-place pile constructed through the cast-in-place pile construction method, on the premise that the stress and safety requirements are met, the construction cost can be saved, and the construction period can be shortened.
本发明公开了一种后插立柱灌注桩施工方法及其构建的灌注桩。本发明的灌注桩施工方法包括：在桩基位置处实施钻孔作业，钻孔得到桩基灌注孔（1）；将预先制备的钢筋笼（2）放置到桩基灌注孔中；将混凝土灌注入桩基灌注孔中；将预先制备的钢管立柱（3）插入到桩基灌注孔内的混凝土中；钻孔作业得到的桩基灌注孔，其上口处具有头部扩大孔段（11）；钢筋笼的上端部具有外扩展头部（21）；将钢筋笼放置到桩基灌注孔中之后，钢筋笼的外扩展头部处于桩基灌注孔的头部扩大孔段内。本发明的灌注桩采用上述灌注桩施工方法施工构建而成。本发明的灌注桩施工方法及其构建的灌注桩在满足受力和安全要求的前提下，能够节约施工成本，缩短施工周期。
