Cable crane construction method and structure for discontinuous bearing cable of suspension bridge
The invention discloses a cable crane construction method for a discontinuous bearing cable of a suspension bridge, which is characterized in that on the basis of a structure where a main cable of the suspension bridge is erected, a cable sling saddle arranged on an upper cross beam of a main tower is omitted, and the end of a midspan bearing cable is directly anchored on the cross beam of the main tower; the construction mode that a bearing cable continuously extends to a side span to serve as a back cable is omitted, and two solutions are adopted to balance the unbalanced horizontal force from the top of the main tower to the midspan. After rigorous stress analysis is conducted on the suspension bridge, the construction method of the discontinuous bearing cable is redesigned, and the problems that in the prior art, when a bridge approach bridge is located on a curve, a cable hanging system back cable needs to penetrate through a bridge floor or pier columns to be installed, the actual difficulty is encountered, and meanwhile the construction cost is high and the construction efficiency is high in the traditional technology are solved. According to the technology, on the premise that safety is guaranteed, the construction difficulty and cost are effectively reduced.
本发明公开了一种用于悬索桥非连续承重索的缆吊施工方法，其特征在于：在悬索桥主缆架设完成的结构基础上，取消设置在主塔上横梁的缆吊索鞍，直接将跨中承重索的端头锚固在主塔横梁上，取消了将承重索连续的延伸到边跨作为背索的施工方式，采用了两种解决途径平衡了主塔塔顶向跨中的不平衡水平力。本发明通过对悬索桥进行严谨的受力分析后，重新设计了一套非连续承重索的施工方法，解决了现有技术中，桥梁引桥处于弯道曲线上缆吊系统背索需要穿越桥面或墩柱安装时遇到的实际困难，同时传统技术施工成本高，本技术在保证安全的前提下，有效降低了施工难度和成本。
