Upright column pile structure adopting enlarged head and construction process thereof
The invention relates to an upright column pile structure adopting an enlarged head and a construction process thereof. The upright column pile structure comprises a foundation pit excavation face, wherein a pile hole is downwards formed in the foundation pit excavation face; the pile hole is a step hole; the pile hole comprises an upper pile hole and a lower pile hole; the size of the upper pile hole is larger than that of the lower pile hole; a step is formed between the upper pile hole and the lower pile hole; a pile foundation is arranged in the pile hole; the pile foundation comprises an upper enlarged section, a middle transition section and a lower standard section; the lower standard section is arranged in the lower pile hole; the upper enlarged section and the middle transition section are arranged in the upper pile hole; a steel upright column is arranged in the upper enlarged section; and the upper end of the steel upright column extends out of the foundation pit excavation face. According to the upright column pile structure adopting the enlarged head and the construction process thereof, the problems of invalid cost generation and construction speed increase in existing construction can be solved.
本发明涉及一种采用扩大头的立柱桩结构及其施工工艺，所述立柱桩结构包括基坑开挖面，所述基坑开挖面向下开设有桩孔，所述桩孔为一台阶孔，所述桩孔包括上桩孔和下桩孔，所述上桩孔尺寸大于下桩孔尺寸，所述上桩孔和下桩孔之间形成台阶，所述桩孔内设置有桩基，所述桩基包括上扩大段、中间过渡段和下标准段，所述下标准段设置于下桩孔内，所述上扩大段和中间过渡段设置于上桩孔内，所述上扩大段内设置有钢立柱，所述钢立柱上端伸出基坑开挖面。本发明一种采用扩大头的立柱桩结构及其施工工艺，它能够解决现有施工中无效成本的产生及提高施工速度的问题。
