Construction method of uplift pile
The invention provides a construction method of an uplift pile, which comprises the following construction steps: step 1, measuring and positioning: positioning an accurate construction position of the uplift pile; 2, pile hole construction is conducted underground at the construction position; 3, a consolidating material is poured into the pile hole; 4, a prefabricated pile body is spirally implanted into the pile hole before the consolidated material is not consolidated, and multiple sets of screwing-in structures are arranged on the outer side of the prefabricated pile body in the axial direction at intervals and used for screwing the prefabricated pile body into the pile hole; the defects that an existing uplift pile overall cast-in-place construction mode is long in construction period and low in construction efficiency are overcome, and the technical problems that a pile sinking mode of a precast pile is large in environment influence, high in geological requirement, prone to damage a pile body, prone to pile explosion and the like are solved.
本发明提供一种抗拔桩的施工方法，包括以下施工步骤：步骤1，测量定位，定位出准确的抗拔桩的施工位置；步骤2，在施工位置向地下进行施工桩孔；步骤3，向桩孔内浇注可固结材料；步骤4，在可固结材料未固结前向桩孔内螺旋植入预制桩体，所述预制桩体外侧沿轴向间隔设置有多组旋入结构用于将预制桩体旋入桩孔；以解决现有的抗拔桩整体现浇方式施工存在施工周期长、施工效率低的弊端，但是预制桩的沉桩方式又存在对环境影响大、对地质要求高且容易损伤桩体及容易出现爆桩等技术问题。
