Replacement structure of existing bracket of cantilever beam bridge and construction method
The invention provides a replacement structure of the existing bracket of a cantilever beam bridge and a construction method. The problem of further development of bracket crack diseases can be fundamentally solved, the cost can be saved, and popularization and implementation are facilitated. The replacement structure of the existing bracket of the cantilever beam bridge comprises an upper bracketend with the cantilever beam bridge and a lower bracket end with the cantilever beam bridge, a steel box beam bracket is installed at the lower bracket end through a high-strength pull rod anchoringsystem and anchoring bolts, a support body is installed on the steel box beam bracket, and the support body makes contact with the beam bottom of the upper bracket end and the beam bottom of the lowerbracket end.
本发明提供了一种悬臂梁桥既有牛腿的替代结构及施工方法，既可以从根本上解决牛腿裂缝病害进一步发展，又可以节约成本，便于推广和实施。一种悬臂梁桥既有牛腿的替代结构，包括带悬臂梁桥的上牛腿端和带悬臂梁桥的下牛腿端，钢箱梁托架通过高强拉杆锚固体系及锚固螺栓安装于下牛腿端，钢箱梁托架上安装支座体，支座体与上牛腿端的梁底及下牛腿端梁底均接触。
