Arch bridge standby tie bar reserving structure and reserving method thereof
The invention discloses an arch bridge standby tie bar reserving structure and a reserving method thereof, and belongs to the technical field of bridge construction. The device comprises a tie bar channel, wherein four groups of tie bars are arranged in the tie bar channel, and tie bar limiting pieces are installed on the two sides of each tie bar. The four groups of tie bars comprise a first tiebar, a second tie bar, a third tie bar and a standby tie bar. According to the invention, the tie bar replacement process during the arch bridge operation period is greatly simplified; important significance is realized for avoiding traffic closure during maintenance operation; reserving the mounting position of one tie bar as a standby tie bar position; when the tie bars reach the service life and need to be replaced, the standby tie bars are installed and tensioned firstly, then the corresponding tie bars are unloaded and replaced in batches, the relative stability of the total horizontal force of the bridge tie bars is kept. By means of the method, it can be guaranteed that the arch bridge tie bars are replaced conveniently, the tie bar replacement cost is reduced, and the constructionperiod is shortened.
本发明公开了一种拱桥备用系杆预留结构及其预留方法，属于桥梁建设技术领域。本发明包括系杆通道，所述的系杆通道的内部设置有系杆，系杆的两侧安装有系杆限位件，系杆设有四组，包括第一系杆、第二系杆、第三系杆和备用系杆。本发明大大简化了拱桥运营期间系杆更换的工序，对于避免维修作业时封闭交通具有重要的意义，将其中一个系杆安装位置予以保留作为备用系杆位，待系杆达到使用寿命需要更换时，先安装并张拉备用系杆，再分批次卸载、更换相应系杆，保持桥梁系杆总水平力的相对稳定，该方法在使用后可保证拱桥系杆更换的便捷，降低系杆更换成本并缩短施工周期。
