Cable-stayed bridge tower beam synchronization system and construction method
The invention relates to a cable-stayed bridge tower beam synchronization system and a construction method. A cable-stayed bridge main tower is provided with a buffer device in the construction process of automatically controlling a hydraulic creeping formwork; a concrete spraying and curing system is arranged on the main beam of the cable-stayed bridge in the front fulcrum hanging basket construction process; a liftable truss structure is adopted for fast formwork erecting; the main tower adjustable temporary transverse supporting system is provided with an anti-falling platform; and a steel pipe column positioning device is arranged on the temporary Z cross brace. The device has the beneficial effects that the buffer device is arranged in the construction process of automatically controlling the hydraulic creeping formwork, so that the impact force is reduced, the service life of the device is prolonged, the construction cost is reduced, and the construction of the main beam and the construction of the main tower can be simultaneously carried out; a concrete spraying and curing system is arranged, and the requirement for rapid curing and protection of main beam concrete of the cable-stayed bridge is met; a lifting truss structure rapid formwork system is adopted, so that the construction difficulty is reduced; and the anti-falling platform is arranged, so that the safety coefficient of on-site construction is effectively improved.
本发明涉及一种斜拉桥塔梁同步体系及施工方法，斜拉桥主塔在自动控制液压爬模施工过程中设置缓冲装置；斜拉桥主梁在前支点挂篮施工过程中设置混凝土喷淋养护系统；采用可升降桁架结构快速支模；主塔可调式临时横向支撑体系设置防坠落平台；临时Z横撑上设置钢管柱定位装置。本发明的有益效果是：在自动控制液压爬模施工过程中设置缓冲装置，减小了冲击力，提高了装置的工作寿命，降低了施工成本，使主梁和主塔的施工可以同时进行；设置混凝土喷淋养护系统，满足斜拉桥主梁混凝土快速养护保护的需求；采用可升降桁架结构快速支模体系，降低了施工难度；设置防坠落平台，有效提高了现场施工的安全系数。
