Temporary pier beam restraint system for large-span cable-stayed bridge
The invention discloses a large-span cable-stayed bridge temporary pier beam restraint system, and relates to the technical field of cable-stayed bridge construction.The device comprises a pier top beam used for being erected on the top of a temporary pier and a movable bearing beam used for connecting a steel box beam and the pier top beam, and the pier top beam comprises a lower distribution beam set and an upper distribution beam set; the lower distributive girder group is arranged at the top of the temporary pier, and the upper distributive girder group is arranged at the top of the lower distributive girder group; the movable bearing beam is arranged at the top of the upper distribution beam group, the movable bearing beam is connected with a lifting lug of the steel box beam through a sliding assembly, and the movable bearing beam is fixed to the upper distribution beam group through a steel anchor cable; a plurality of pressure transmitting assemblies are arranged between the movable bearing beam and the pier top beam, and the sliding base can slide along the movable bearing beam. The structure cost of the temporary pier is reduced, the safety coefficient of the temporary pier is improved, the temporary pier can adapt to the beam bottom line shape in the construction stage, the construction difficulty is reduced, and operation is convenient.
本发明公开了一种大跨斜拉桥临时墩墩梁约束系统，涉及斜拉桥施工技术领域，该装置包括用于架设在临时墩顶部的墩顶梁和用于连接钢箱梁和所述墩顶梁的活动式垫梁，所述墩顶梁包括下分配梁组和上分配梁组，所述下分配梁组设置在临时墩的顶部，所述上分配梁组设置在所述下分配梁组的顶部；所述活动式垫梁设置在所述上分配梁组的顶部，所述活动式垫梁通过滑动组件与所述钢箱梁的吊耳相连，所述活动式垫梁通过钢锚索与上分配梁组固定；所述活动式垫梁与所述墩顶梁之间设有多个传压组件，且所述滑座可以沿着所述活动式垫梁滑动。本申请降低了临时墩结构成本，提高临时墩的安全系数，能够适配施工阶段的梁底线形，降低施工难度，方便作业。
