Cable-stayed bridge structure beneficial to swivel construction and construction method
The invention relates to the technical field of bridge construction, in particular to a cable-stayed bridge structure beneficial to swivel construction and a construction method.The first aspect is that the cable-stayed bridge structure comprises a main tower and a main beam, a swivel system is arranged at the bottom of the main tower, and the main tower comprises a main-tower-shaped steel shell and concrete poured into the steel shell; the main beam comprises a middle box and cantilever arms located on the two sides of the middle box in the transverse bridge direction. Before and when the main tower and the main beam are integrally rotated by means of the rotation system, the main tower is only of a tower-shaped structure composed of a steel shell, and the main beam only comprises a middle box. On the second aspect, the invention further provides a construction method based on the cable-stayed bridge structure. According to the cable-stayed bridge structure and the construction method, the weight of the rotation structure and the rotation difficulty can be effectively reduced, and the construction risk is reduced.
本申请涉及桥梁施工技术领域，涉及一种利于转体施工的斜拉桥结构及施工方法，第一方面，斜拉桥结构包含主塔和主梁，所述主塔底部设置转体系统，且主塔包含主塔形状的钢壳和浇筑于钢壳内部的混凝土；所述主梁包含中间箱和位于中间箱横桥向两侧的挑臂；所述主塔和主梁依靠转体系统整体转体前和转体时，所述主塔仅呈钢壳组成的塔状结构，所述主梁仅包含中间箱。第二方面，本申请还提供了一种基于上述斜拉桥结构的施工方法。本申请的斜拉桥结构及施工方法，可以有效降低转体结构重量和转体难度，降低施工风险。
