Large-tonnage cable-stayed cluster rock anchor system, construction method and suspension bridge
The invention discloses a large-tonnage cable-stayed cluster rock anchor system. The large-tonnage cable-stayed cluster rock anchor system comprises an anchor hole, an anchor rod body structure and high-strength steel fiber concrete, wherein an anchor chamber is arranged in the anchor hole; the anchor rod body structure comprises a cluster anchor rod main reinforcement assembly and a chain type sliding ring assembly sleeved on the cluster anchor rod main reinforcement assembly, 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 to form a wave-shaped string-type structure after being installed and positioned in the anchor hole, and the wave-shaped string-type structure is located in the anchor chamber; the high-strength steel fiber concrete is poured in the anchor hole and is held and wrapped with the chain type sliding ring assembly to bear pressure. The invention further discloses a construction method of the rock anchor system and a suspension bridge comprising the same. According to the large-tonnage cable-stayed cluster rock anchor system, the cluster anchor rod main reinforcement assembly is used for bearing tension, the chain type sliding ring assembly, the high-strength steel fiber concrete and rock mass bear the pressure together, structural stress is definite, and stress performance is reliable.
本发明公开了一种大吨位斜拉集束岩锚体系，包括锚孔、锚杆主体结构和高强钢纤维混凝土；锚孔内设置有锚室，锚杆主体结构包括集束锚杆主筋组件及套在其上的链式滑环组件；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；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，波折型串株式构造位于锚室内；高强钢纤维混凝土浇筑在锚孔内，并与链式滑环组件握裹一起进行承压。本发明还公开了上述岩锚体系的施工方法及含有其的悬索桥。本发明的岩锚体系利用集束锚杆主筋组件进行承拉，链式滑环组件、高强钢纤维混凝土和岩体一起进行承压，结构受力明确，受力性能可靠。
