Non-prestress composite anchor cable uplift pile and preparation method thereof
The invention belongs to the field of underground construction, and discloses a non-prestress composite anchor cable uplift pile. The uplift pile is characterized by comprising an uplift pile cage outer wall, an uplift pile cage inner wall, a composite anchor cable and a filler, wherein the composite anchor cable is arranged between the uplift pile cage outer wall and the uplift pile cage 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 a corrosive from a full-bonding anchorcable body. According to the uplift pile, the problems that a steel strand cannot be placed into the bottom of a hole due to disorder in the hole entering process, the steel strand is prone to being corroded, and particularly underground water enters concrete to generate tiny cracks due to tensile stress to cause corrosion can be solved, and the overall supporting performance of a pile cage is good.
本发明属于地下施工领域，本发明公开了一种无预应力复合锚索抗拔桩，抗拔桩，其特征在于，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，隔离体将腐蚀物和全粘结锚索隔开；填装物。本发明能够避免钢绞线入孔过程中会搅乱无法放入孔底，钢绞线容易被腐蚀、尤其是地下水进入混凝土因拉应力产生微小裂缝导致的腐蚀的问题，且本发明桩笼整体支撑性好。
