Construction method for large-span lower cross beam of main tower of single-tower cable-stayed bridge in complex environment
The invention relates to a construction method for a large-span lower cross beam of a single-tower cable-stayed bridge main tower in a complex environment. Comprising a construction technology of replacing a steel pipe pile with a bearing platform cushion layer discrete material, a closed pre-embedding technology of firstly installing a wooden box on a steel pipe column connecting steel plate, a technology of symmetrically overhanging steel corbels on the steel pipe pile, a steel corbel firstly-installing cross beam shifting installation system, a steel corbel later-installing main cross beam hanging auxiliary installation system and a technology of hooping a tower column to stabilize the steel pipe pile. The construction progress of the large-span lower cross beam of the main tower of the single-tower cable-stayed bridge in a complex environment can be improved, the construction safety is ensured, and the construction cost is saved.
本发明涉及一种复杂环境独塔式斜拉桥主塔大跨度下横梁施工方法，包括承台垫层散体材料置换钢管桩施工技术、钢管柱连接钢板先安装木盒封闭预埋技术、钢管桩对称悬挑钢牛腿技术、钢牛腿先安装横梁移位安装体系、钢牛腿后安装主横梁吊挂辅助安装体系以及抱箍塔柱稳固钢管桩技术，可提高复杂环境独塔式斜拉桥主塔大跨度下横梁施工的施工进度，保证施工安全，节约施工成本。
