Combined anchoring structure for prefabricated main cable tower end of suspension bridge
The invention discloses a combined anchoring structure for a prefabricated main cable tower end of a suspension bridge, and relates to the technical field of bridge engineering. An embedded pipe is embedded in a bridge tower, and the front end of the embedded pipe is fixedly connected with an anchor backing plate; the steel pull rod, the cable anchor head, the damping ring, the limiting structure and the reinforcing ring are sequentially and coaxially arranged in the embedded pipe from front to back, the rear end of the steel pull rod is connected with the front end of the cable anchor head in a threaded fit mode, the nut is fastened to the steel pull rod in a threaded fit mode, the main cable is sleeved with the damping ring and the limiting structure in a matched mode, and the damping ring and the limiting structure are matched to be tensioned and abut against the rear end of the cable anchor head. The embedded pipe, the limiting structure and the reinforcing ring form an integral anchoring structure, good stability is achieved, anchoring failure caused by sliding and deviation of the main cable in the embedded pipe can be effectively avoided, meanwhile, stress generated by the main cable bearing tensile force in the anchoring structure can be dispersedly borne by the whole anchoring structure and the steel pull rod and transmitted to a bridge tower, and the anchoring effect is improved. Compared with an existing anchoring structure, the stress concentration degree of an anchoring area is effectively reduced, and the overall compression resistance of the structure is improved.
本发明公开了一种悬索桥预制主缆塔端组合式锚固结构，涉及桥梁工程技术领域，预埋管预埋设于桥塔内，其前端固连有锚垫板；钢拉杆、缆索锚头、减震环、限位结构和加固环由前至后依次共轴设于预埋管内，钢拉杆的后端与缆索锚头的前端螺纹配合连接，螺母螺纹配合紧固至钢拉杆上，减震环和限位结构配合套设于主缆外，两者配合涨紧，抵紧缆索锚头后端。本发明预埋管、限位结构和加固环构成整体式的锚固结构，具备较好的稳定性，能有效避免主缆在预埋管内滑动、偏移导致的锚固失效，同时锚固结构中因主缆承受拉力产生的应力可由整个锚固结构和钢拉杆分散承担传递至桥塔，相较于现有的锚固结构有效降低锚固区的应力集中程度，提高了结构的整体抗压性能。
