Steel pull rod anchoring system for anchoring main cable of suspension bridge and steel pull rod replacing method
The invention discloses a steel pull rod anchoring system for anchoring a main cable of a suspension bridge and a steel pull rod replacing method, the steel pull rod anchoring system comprises a cable strand connecting mechanism connected with a cable strand and a prestress anchoring mechanism anchored in an anchorage, and the cable strand connecting mechanism is connected to the tensioning end of the prestress anchoring mechanism through a connecting flat plate; the position, used for anchoring the prestress anchoring mechanism, of the anchorage is provided with a rod penetrating channel. The prestress anchoring mechanism is provided with steel pull rods, the steel pull rods are installed in the corresponding rod penetrating channels in a penetrating mode, the anchoring ends of the steel pull rods are connected with anchoring end locking assemblies at the rear anchoring ends of the corresponding rod penetrating channels, and the tensioning ends of the steel pull rods extend out of the corresponding rod penetrating channels and are connected with the connecting flat plate through the tensioning end locking assemblies. And an annular space in clearance fit is formed between the outer wall of the steel pull rod and the inner wall of the corresponding rod penetrating channel. The steel pull rods are anchored in the corresponding rod penetrating channels in the anchorage in a rod penetrating mode in a non-adhesive mode, on one hand, prestress tension can be reliably kept, and on the other hand, the steel pull rods can be replaced after stress is unloaded.
本发明公开了一种悬索桥主缆锚固用钢拉杆锚固系统及钢拉杆更换方法，钢拉杆锚固系统包括连接索股的索股连接机构及在锚碇中锚固的预应力锚固机构，索股连接机构通过连接平板连接在预应力锚固机构张拉端；锚碇用作锚固预应力锚固机构的位置具有穿杆通道；预应力锚固机构具有钢拉杆，钢拉杆穿装在对应穿杆通道内，钢拉杆的锚固端在对应穿杆通道的后锚端处连接有锚固端锁紧组件，钢拉杆的张拉端延伸出对应穿杆通道、通过张拉端锁紧组件与连接平板连接，且钢拉杆的外壁与对应穿杆通道的内壁之间形成间隙配合的环空。本发明将钢拉杆以穿杆方式、非粘接的锚固于锚碇中的对应穿杆通道内，一方面能够使预应力张拉可靠保持，二方面在受力卸载之后可更换。
