Cable-stayed bridge swivel system
The invention provides a cable-stayed bridge swivel system, which is characterized in that a swivel structure is arranged on the top surface of a bearing platform, the swivel structure is arranged around the outer ring of a pier column, at least one pair of supporting legs is arranged on the swivel structure, the pair of supporting legs are oppositely and symmetrically arranged, the bottoms of the supporting legs are fixed on the swivel structure and can rotate along with the swivel structure, and the supporting legs are fixed on the swivel structure. And the supporting legs are fixedly connected with the pier column. According to the invention, a swivel system composed of the swivel structure and the supporting legs can assist in straight swivel of old and dangerous cable-stayed bridges and can also assist in straight swivel of newly-built cable-stayed bridges, the pier column and the bearing platform are in a disconnected state before swivel, and the swivel structure can drive the supporting legs, the pier column and the main beam to swivel. And moreover, the swivel system keeps the original stress distribution of the upper structure of the bridge and the main beam to the maximum extent, and the original stress point of the main beam is not changed, so that the main beam of the old bridge and the dangerous bridge is prevented from generating potential safety hazards due to stress change in the subsequent straight swivel process.
本发明提供了一种斜拉桥转体系统，在所述承台的顶面上设有转体结构，所述转体结构环绕墩柱外圈设置，在所述转体结构上设有至少一对支撑脚，一对支撑脚相向对称设置，所述支撑脚的底部固定于转体结构上并可跟随转体结构旋转，所述支撑脚与墩柱固定连接。本发明中，转体结构和支撑脚组成的转体系统可辅助老、危斜拉桥进行平直转体，也可辅助新建斜拉桥进行平直转体，在转体前墩柱与承台处于断开状态，转体结构可带动支撑脚、墩柱和主梁进行转体，而且该转体系统最大限度了保持了桥梁上部结构、主梁的原有受力分布，主梁的原有受力点并未变动，使得老桥、危桥的主梁不至于在后续的平直转体过程中因受力发生变化而产生安全隐患。
