Novel unbonded post-tensioning prestress uplift pile structure
The invention relates to a novel unbonded post-tensioning prestress uplift pile structure. The novel unbonded post-tensioning prestress uplift pile structure comprises a pile hole, a reinforcement cage is placed in the pile hole, concrete is poured in the pile hole, the concrete and the reinforcement cage form an uplift pile body, a plurality of pile bottom anchoring devices are arranged at the bottom of the uplift pile body, a plurality of pile top anchoring devices corresponding to the pile bottom anchoring devices are arranged at the top of the uplift pile body, unbonded steel strands are arranged on the pile bottom anchoring devices, and the tops of the unbonded steel strands are connected with the pile top anchoring devices. The technical problem that the uplift pile is prone to rusting in the using process, and consequently the function of the uplift pile fails is solved.
本发明涉及一种新型无粘结后张拉预应力抗拔桩结构，包括桩孔，所述桩孔内放置有钢筋笼，所述桩孔内浇筑有混凝土，所述混凝土和所述钢筋笼形成抗拔桩本体，所述抗拔桩本体底部设有若干桩底锚固装置，所述抗拔桩本体顶部设有与若干所述桩底锚固装置对应的若干桩顶锚固装置，所述桩底锚固装置上设置有无粘结钢绞线，所述无粘结钢绞线的顶部与所述桩顶锚固装置相连。解决了抗拔桩在使用过程中容易被锈蚀，导致抗拔桩功能失效的技术问题。
