Large-tonnage prestress cluster anchor rod assembly used in rock anchor
The invention discloses a large-tonnage prestress cluster anchor rod assembly used in a rock anchor. The large-tonnage prestress cluster anchor rod assembly comprises a cluster anchor rod main reinforcement assembly and a chain type sliding ring assembly sleeved on the cluster anchor rod main reinforcement assembly, wherein the lowermost end of the chain type sliding ring assembly is fixedly connected to the bottom of the cluster anchor rod main reinforcement assembly; the chain type sliding ring assembly can freely slide along the cluster anchor rod main reinforcement assembly and can be unfolded under the action of gravity after being installed and positioned in an anchor hole to form a wave-shaped string-type structure. When the large-tonnage prestress cluster anchor rod assembly is used for the rock anchor, the cluster anchor rod main reinforcement assembly is used for bearing tension, the chain type sliding ring assembly can be matched with high-strength steel fiber concrete and rock mass to bear pressure together, structural stress is definite, a large outer axial load can be borne, the application range is wide, and stress performance is reliable; the prestress cluster anchor rod assembly can be manufactured and assembled in a full-assembly mode in a factory, so that site construction measures are greatly simplified, and site construction safety and engineering construction quality are improved.
本发明公开一种用于岩锚中的大吨位预应力集束锚杆组件，包括集束锚杆主筋组件及套在其上的链式滑环组件；所述链式滑环组件的最下端固定连接在集束锚杆主筋组件底部；所述链式滑环组件可沿集束锚杆主筋组件自由滑动，并且在锚孔内安装定位后能在重力作用下展开形成波折型串株式构造。本发明的预应力集束锚杆组件在用于岩锚时，利用集束锚杆主筋组件进行承拉，链式滑环组件可配合高强钢纤维混凝土和岩体一起进行承压，结构受力明确，能承受较大的外轴向荷载，适用范围广，受力性能可靠；且上述预应力集束锚杆组件可以在工厂实现制作和全装配化组装，大大简化了现场施工措施，提升了现场施工安全性和工程建设品质。
