Large-span string truss high-altitude cable replacement construction system and construction method
The invention relates to a large-span string truss high-altitude cable replacement construction system and method. The construction system comprises a large-span string truss which comprises an upper truss, a cable to be replaced and a plurality of supporting rods; the temporary cable assembly at least comprises two temporary cables, the two temporary cables are installed over the to-be-replaced cable, and the two ends of the temporary cables are anchored to the two ends of the to-be-replaced cable respectively; the temporary supporting rod assemblies are arranged on the two temporary cables in the mode that the temporary supporting rod assemblies and the supporting rods are alternately arranged at intervals, the lower ends of the temporary supporting rod assemblies are fixedly connected with the two temporary cables, and the upper ends of the temporary supporting rod assemblies are fixedly connected with lower chord nodes of the upper truss; when the two temporary cables are tensioned, the upper truss is synchronously supported by the multiple sets of temporary supporting rod assemblies. According to the high-altitude cable replacement construction system and method, replacement of the lower inhaul cable is completed while the upper structure is not changed, and the high-altitude cable replacement construction system and method have the advantages of being high in construction speed, small in construction space requirement and high in cyclic utilization rate.
本发明涉及一种大跨度张弦桁架高空换索施工系统及施工方法。该施工系统包括：大跨度张弦桁架，包括上部桁架、待更换索和多根撑杆；临时索组件，至少包括两根临时索，两根临时索安装于待更换索的正上方，并且两端分别锚固于待更换索两端处；临时撑杆组件，多组临时撑杆组件以与多根撑杆间隔交替的方式布置于两根临时索上，并且临时撑杆组件下端与两根临时索连接固定，上端与上部桁架的下弦节点连接固定；两根临时索在被张拉时，借由多组临时撑杆组件同步支撑起上部桁架。本发明提供的高空换索施工系统及施工方法，在未改变上部结构的同时完成下部拉索的更换，具有施工速度快、施工空间要求小和可循环利用率高的特点。
