Construction method of uplift pile in granite area
The invention discloses a construction method of an uplift pile in a granite area, which comprises the following steps: S1, drilling on the ground to form a pile hole; s2, reaming is conducted on the inner wall of the pile hole to form a through cavity; s3, a plurality of prestress blocks stretch into the pile hole, and the outer walls of the prestress blocks are attached to the inner wall of the pile hole; s4, the prestressed blocks are connected through welding connecting ribs; s5, a protection plate extends into the pile hole, and the outer wall of the protection plate is attached to the inner wall of the prestress block; s6, concrete is poured into the prestressed blocks, and prestressed piles are formed after the concrete is condensed; s7, the protection plate is detached, and the reinforcement cage extends into the pile hole; s8, concrete is poured into the reinforcement cage, and construction is completed after the concrete is coagulated; the first anti-pulling body and the second anti-pulling body are arranged on the body, the upward stress of the reinforcement cage can be prevented, the overall strength of the anti-pulling device is improved, and the stability and safety of the construction mode are ensured.
本发明公开了一种花岗岩地区抗拔桩的施工方法，包括以下步骤：S1：在地面上进行钻孔，以形成桩孔；S2：对桩孔的内壁上进行扩孔，以形成通腔；S3：将多个预应力块伸入到桩孔内，并将预应力块的外壁与桩孔的内壁贴合；S4：预应力块之间通过焊接连接筋连接；S5：向桩孔内伸入护板，护板的外壁贴合在预应力块的内壁上；S6：向预应力块内浇筑混凝土，混凝土凝结后形成预应力桩；S7：拆掉护板，将钢筋笼伸入到桩孔内；S8：向钢筋笼内浇筑混凝土，混凝土凝结后完成施工；本发明在本体上设置有第一抗拔体和第二抗拔体，可以防止钢筋笼和向上的应力，增加本发明的整体强度，确保施工方式的稳定性和安全性。
