Pre-stressed anchor cable structure for rapid emergency rescue of floating underground engineering and construction method of pre-stressed anchor cable structure
The invention relates to the technical field of building construction, in particular to a pre-stressed anchor cable structure for rapid emergency rescue of floating underground engineering and a construction method of the pre-stressed anchor cable structure. The pre-stressed anchor cable structure comprises an anchor cable, an anchoring mechanism, tensioning equipment and a back-jacking device; according to the pre-stressed anchor cable structure for rapid emergency rescue of the floating underground engineering and the construction method of the pre-stressed anchor cable structure, pre-stress is applied to the anchor cable through the anchoring mechanism and the tensioning equipment, downward pressure can be actively generated on the bottom plate, the bottom plate generates downward deformation relative to upward protruding deformation, floating deformation is eliminated, and the construction efficiency is improved. Meanwhile, active pressure is generated on the bottom plate, passive floating of the underground engineering is prevented, floating deformation of the bottom plate can be controlled, the situation that concrete at the top of the bottom plate is pulled and cracks due to further protruding of the bottom plate can be prevented, and the purpose of rapid emergency rescue of the floating underground engineering is achieved.
本发明涉及建筑施工技术领域，特别涉及用于上浮地下工程快速抢险的预应力锚索结构及其施工方法，包括锚索、锚固机构、张拉设备和回顶器，所述锚固机构包括锚垫筒、装配式锚具以及夹片；本发明提供的用于上浮地下工程快速抢险的预应力锚索结构及其施工方法，本发明通过锚固机构和张拉设备对锚索施加预应力，能够对底板主动产生下压力，使得底板产生相对于向上隆起变形的向下变形，消除上浮变形，同时对底板产生主动的压力，既防止地下工程被动上浮，又能控制底板的上浮变形量，还能防止底板进一步隆起导致底板顶部混凝土受拉而开裂，实现上浮地下工程快速抢险的目的。
