摘要
介绍广西贵港罗泊湾码头现浇箱梁在大跨度高架施工的情况下,采用贝雷桁架作为托架,外悬臂端采用钢管斜支撑的施工方法。为该梁施工避免洪水及船舶影响、减小支架下沉、确保施工安全打下良好基础,同时为同类型大跨度的箱梁施工提供参考。
The construction method of cast-in-situ box girder in Guangxi Guigang Luobo Bay Dock project is presented. In the case of overhead large-span construction, Beret trusses were used as the brackets and the outer ends of cantilevers were supported with inclined steel pipes. By the method, we can avoid the influence from flood and vessels during the construction and reduce the sinking of brackets and thus ensure safe construction. Meanwhile, it can provide a reference for construction of large-span box girders of the same kind.
