Bridge rotation system auxiliary supporting system and stress debugging and conversion construction method
The invention relates to an auxiliary supporting system of a bridge rotation system and a stress debugging and conversion construction method, and belongs to the technical field of bridge rotation. The invention discloses a stress debugging method. Comprising the steps that a steel plate is embedded in the bottom of a contact face beam, the flatness and elevation of the upper plane of a trolley frame meet the design requirements, jacks are connected with an oil way, synchronous loading is conducted, a method for configuring a pressure energy accumulator is adopted to cope with pressure compensation, and the display value of a pressure gauge arranged between the bottom of the beam and the trolley frame is compared and monitored. And setting the loading sequence of all the auxiliary supporting systems in the multi-point supporting bridge swivel system. The corresponding conversion construction method comprises the steps of arranging a rubber pad, arranging a plurality of groups of inclined prismatic horizontal limiting structures, correspondingly and synchronously loading, installing, welding and solidifying the components, and stably unloading the components to the horizontal limiting structures step by step. The rotating quality and safety can be effectively improved, and the construction progress is shortened.
本发明涉及一种桥梁转体体系辅助支承系统及受力调试与转换施工方法，属于桥梁转体技术领域。受力调试方法，包括接触面梁底预埋钢板、台车架上平面的平整度及高程满足设计要求、千斤顶连接油路以及同步加载、采用配置压力蓄能器的方法应对压力补偿、对梁底与台车架间设置的压力表显示值进行比对监测、设置多点支承桥梁转体体系中的所有辅助支承系统加载顺序的步骤。而对应转换施工方法包括设置橡胶垫、设置斜置棱形的多组水平限位结构以及相应的同步加载、构件组焊固结、逐级稳步卸载到水平限位结构的步骤。本发明能有效提高转体的质量和安全性，缩短施工进度。
