Cable-stayed bridge girder front fulcrum hanging basket and suspension casting process
The invention relates to the technical field of cable-stayed bridge main beams, in particular to a cable-stayed bridge main beam front fulcrum hanging basket and a cantilever casting technology, the cable-stayed bridge main beam front fulcrum hanging basket comprises a bearing platform, and structure-adjustable formwork systems are fixed to the two sides of the walking end of the bearing platform. According to the front fulcrum hanging basket for the main beam of the cable-stayed bridge, the electric control type suspension system is installed on the bearing platform, the front fulcrum hanging basket can adapt to main beams of the cable-stayed bridge of different structures by adjusting the angle and the height according to needs, and the applicability is quite wide; the hanging basket is pre-pressed by adopting a water bag method, so that the loading and unloading construction efficiency is improved, the labor input is reduced, the data acquisition precision is improved, and the construction cost is reduced; the hanging basket cantilever and the combined platform are additionally arranged on the front cross beam cantilever of the front fulcrum hanging basket to serve as a bearing platform for main beam closure section construction, closure section construction can be conducted without moving the hanging basket forwards, the problem that a formwork support is additionally arranged on the closure section is avoided, the construction period of the closure section is guaranteed, the construction cost is reduced, and main beam closure precision is improved.
本发明涉及斜拉桥主梁技术领域，尤其是一种斜拉桥主梁前支点挂篮以及悬浇工艺，包括承载平台，承载平台行走端两侧固定有结构可调式模板系统。本发明的一种斜拉桥主梁前支点挂篮通过在承载平台上安装有电控式悬吊系统，可以根据需要通过角度和高度的调节来适配不同结构的斜拉桥主梁，适用性十分广泛；采用水袋法预压挂篮，提高了加载、卸载的施工效率，减少劳动力投入，提高数据采集精度，降低了施工成本；采用在前支点挂篮前横梁悬臂增设挂篮悬臂和组合平台，作为主梁合拢段施工的承载平台，不用前移挂篮就可进行合拢段施工，避免了合拢段另设模板支架的问题，保障了合拢段施工工期，降低了施工成本，提高主梁精度合拢。
