Cable saddle system for replacing main cable of suspension bridge
The invention belongs to the technical field of bridge construction, and discloses a cable saddle system for replacing a main cable of a suspension bridge, which comprises an original cable saddle part arranged on a bridge tower body; the straddle part comprises a pair of linkage shells, the original cable saddle part is located between the pair of linkage shells, the two linkage shells are connected, the sides, close to the original cable saddle part, of the linkage shells are matched with the outer wall of the original cable saddle part to form a pouring space, and a post-pouring concrete layer is poured in the pouring space; the new cable saddle part strides over the original cable saddle part and is used for mounting a new main cable, and a base anchor rod of the new cable saddle part is pre-buried in the post-cast concrete layer; the two sides of the outer side shell of the linkage shell are fixedly connected with cable saddle two-end shells respectively, and the outer side shell, the bottom shell, the cable saddle two-end shells and the saddle body of the original cable saddle part are matched to form a pouring space used for pouring a post-pouring concrete layer. When the main cable is replaced, a temporary main cable and main beam temporary supporting system does not need to be established, an original cable saddle does not need to be specially customized, and the construction difficulty and the construction cost are reduced.
本发明属于桥梁建筑技术领域，公开一种用于悬索桥主缆更换的索鞍系统，包括：原索鞍部，设置于桥塔塔体上；骑跨部，包括一对联动壳，原索鞍部位于一对联动壳之间，两联动壳连接，联动壳靠近原索鞍部的一侧与原索鞍部外壁配合形成一浇筑空间，浇筑空间内浇筑有后浇混凝土层；新索鞍部，骑跨在原索鞍部上方且用于安装新主缆，新索鞍部的底座锚杆预埋在后浇混凝土层内；联动壳的外侧壳两侧分别固接有索鞍两端壳，且其外侧壳、底部壳、索鞍两端壳、原索鞍部的鞍体配合形成用于浇筑后浇混凝土层浇筑空间。本发明能够实现对主缆进行更换时，不需要建立临时主缆及主梁临时支撑体系，以及不需要特殊定制原索鞍，降低施工难度和施工成本。
