Uplift pile and construction method thereof
The invention relates to the technical field of pile foundations, in particular to an uplift pile and a construction method thereof.The uplift pile comprises a pile body, the pile body is provided with an embedded section inserted into the ground and a side circumferential face connected with the embedded section; the anti-pulling mechanism is arranged on the embedded section, the anti-pulling mechanism comprises a plurality of anti-pulling plates, and the plurality of anti-pulling plates can stretch out and draw back in the radial direction of the pile body; and the rotating shaft is rotationally connected into the pile body, one end of the rotating shaft is connected with the anti-pulling mechanism, and the rotating shaft rotates to drive the anti-pulling plates to stretch out and draw back in the radial direction so that the opposite side circumferential faces of the multiple anti-pulling plates can stretch out or retract inwards. When the rotating shaft rotates to drive the anti-pulling plates to stretch out and draw back in the radial direction and the multiple anti-pulling plates stretch out relative to the side circumferential face, the contact area of the anti-pulling pile and a soil body is increased, the bearing capacity of the anti-pulling pile is improved, the length or diameter of the anti-pulling pile can be reduced while the bearing capacity is guaranteed, and cost is reduced; when the multiple uplift plates retract inwards relative to the side circumferential face, the uplift pile can be pulled out and recycled more easily.
本申请涉及桩基技术领域，具体提供了一种抗拔桩及其施工方法，抗拔桩包括：桩体，桩体具有插入地下的埋入段，以及与埋入段连接的侧周面；抗拔机构，抗拔机构设置于埋入段上，抗拔机构包括若干抗拔板，若干抗拔板均可沿桩体的径向伸缩；转轴，转轴转动连接于桩体中，且转轴的一端与抗拔机构连接，转轴通过转动带动抗拔板进行径向伸缩，以使若干抗拔板相对侧周面伸出或内缩。通过使转轴转动，带动所述抗拔板进行径向伸缩，若干所述抗拔板相对所述侧周面伸出时，抗拔桩与土体的接触面积增加，使抗拔桩的承载能力提高，可以在保障承载能力的同时，降低了抗拔桩的长度或直径，减少了成本；若干所述抗拔板相对所述侧周面内缩时，抗拔桩更易拔出回收。
