Incremental launching construction method for large-cantilever spine beam single-tower cable-stayed bridge
The invention discloses a large-cantilever spine beam single-tower cable-stayed bridge incremental launching construction method which comprises spine beams, a 50t crawler-type weight transporter is arranged below each spine beam on the two sides of an assembled beam section, double-spliced stiffening I-shaped steel is arranged above the crawler-type weight transporter, it is ensured that the beam section is stressed in a balanced mode during incremental launching, meanwhile, a limiting plate is arranged, and the limiting plate is arranged above the crawler-type weight transporter. The pushing jack is used for pushing and moving the beam section through the action force applied by the baffle, the supporting plate, the operation force rod and the like, so that the flow progressive construction operation of the large-cantilever spine beam modular bridge structure can be improved, the safety control of the construction operation and the improvement of the working efficiency are facilitated, and the construction characteristics of the modular bridge structure are met; the use of large-tonnage hoisting machinery can be reduced, and the input control of engineering construction cost is facilitated.
本发明公开了一种大悬臂脊骨梁独塔斜拉桥顶推施工方法，包括脊骨梁，在组拼梁段两侧每个脊骨梁下设置50t履带式重物移运器，履带式重物移运器上方设置双拼加劲工字钢，确保顶推时梁段受力均衡，同时设置限位板，确保顶推施工的安全性，顶推千斤顶通过挡板、支撑板、作业力杆等施加作用力是的梁段顶推移动，可以提高大悬臂脊骨梁模块化桥梁结构流水递进施工作业，有利于施工作业的安全控制和工作效率的提升，符合模块化桥梁结构施工特点；可以减少大吨位吊装机械的使用，有利于工程施工成本的投入控制。
