Uplift pile, pile structure, pile body, base, fixed connection assembly and construction method
The uplift pile comprises a pile hole and a pile structure, wherein the pile hole is formed by extending from the earth surface to the stratum in a concave mode, and the pile structure is arranged in the pile hole in the axial direction of the pile hole. The pile structure comprises a pile body and a tie bar, the pile body is a structural object composed of reinforced concrete or/and a steel structure, the pile body is fixedly embedded in the lower end of the pile hole, the lower end of the tie bar is connected with the pile body, and the upper end of the tie bar is located above a pile hole opening of the pile hole and used for being connected with an external connecting component; an empty pile without a pile body in the pile hole is arranged between the top surface of the pile body and the opening of the pile hole, and the empty pile is a pile hole cavity, or/and a backfill soil body in the pile hole cavity, or/and a self-falling soil body formed by retraction or/and collapse of a hole wall soil layer of the pile hole cavity. In the uplift pile structure, the pile body does not generate downward relative displacement relative to the stratum, the phenomenon of up-down reciprocating displacement relative to the stratum is avoided, the friction resistance strength, especially the long-term friction resistance strength, of the pile body and the stratum is guaranteed, and the risk that the friction resistance strength is reduced or fails greatly is avoided.
本发明公开了一种抗拔桩，包括：由地表面向地层中内凹延伸形成的桩孔、沿桩孔的轴向布设于桩孔内的桩构；桩构包括桩体和拉筋，桩体为钢筋混凝土或/和钢结构构成的结构物，且桩体嵌固于桩孔的下端，拉筋的下端连接桩体，拉筋的上端位于桩孔的桩孔孔口的上方用于连接外连构件；桩体的顶面至桩孔孔口之间为桩孔内无桩体的空桩，空桩为桩孔空腔，或/和为桩孔空腔内的回填土体，或/和为桩孔空腔的孔壁土层回缩或/和塌落的自落土体。本发明抗拔桩结构中，桩体不会发生相对于地层的向下相对位移，不会产生相对于地层的上下来回反复位移的现象，桩体与地层的摩阻强度尤其是长期摩阻强度有保障，不会出现较大的摩阻强度下降或失效的风险。
