Expanded-base type pre-stressed composite anchor cable uplift pile and preparation method thereof
The invention belongs to the field of underground construction, and particularly relates to an expanded-base type pre-stressed composite anchor cable uplift pile. The expanded-base type pre-stressed composite anchor cable uplift pile is characterized by comprising an uplift pile composite reinforcement cage, a composite anchor cable, a head expanding part and a filler, wherein the uplift pile composite reinforcement cage comprises an uplift pile cage outer wall and an uplift pile cage inner wall; the composite anchor cable is arranged between the uplift pile cage outer wall and the uplift pilecage inner wall, the composite anchor cable is composed of an isolation body and an uplift anchor cable body arranged in the isolation body, and the isolation body separates the corrosives from the uplift anchor cable body; the head expanding part is arranged at the drilling bottom; and the bottom anchoring end of the uplift pile composite reinforcement cage is arranged in the head expanding part. The expanded-base type pre-stressed composite anchor cable uplift pile is easy to drill, easy to construct, resistant to corrosion, good in supporting performance of the overall pile cage, high in uplift bearing performance of the bottom of the pile body and not prone to breaking of the pile top.
本发明属于地下施工领域，具体涉及一种扩底式预应力复合锚索抗拔桩，其特征在于，包括：抗拔桩复合钢筋笼，其包括抗拔桩笼外壁、抗拔桩笼内壁；复合锚索，复合锚索设置在抗拔桩笼外壁和抗拔桩笼内壁之间，复合锚索由隔离体、设置在隔离体内的抗拔锚索组成，隔离体将腐蚀物和抗拔锚索隔开；钻孔底部设置扩头部；抗拔桩复合钢筋笼底部锚固端设置在扩头部内；填装物。本发明易入孔易施工、抗腐蚀、桩笼整体支撑性好、桩体底部抗拔承载性能强、桩顶不易破碎。
