Double-limb thin-wall high pier 0 # section bracket structure and construction method thereof
The invention discloses a double-limb thin-wall high pier 0 # section bracket structure and a construction method thereof, and belongs to the technical field of bridge construction. The bracket structure comprises two pier bodies, a truss supporting platform, a bailey beam supporting platform and two supporting mechanisms, the two supporting mechanisms are arranged side by side and arranged on the two pier bodies in a one-to-one correspondence mode, the truss supporting platform is arranged on the two supporting mechanisms, the bailey beam supporting platform is arranged on the truss supporting platform, and the two supporting mechanisms are arranged on the two pier bodies in a one-to-one correspondence mode. And a bottom template is arranged on the bailey beam supporting platform. A pre-embedded steel plate box and an opposite-pulling pre-embedded steel pipe are adopted, steel corbels are oppositely pulled on the two sides of a pier body through 40 cr opposite-pulling lead screws, a steel truss and a bailey beam are installed on an unloading part sand cylinder to form a bracket structure system, and the defects that a triangular bracket structure system needs a large amount of high-altitude welding, the number of brackets is large, cost is high, and the hoisting safety risk is high are overcome.
本发明公开了一种双肢薄壁高墩0#段托架结构及其施工方法，属于桥梁施工技术领域。该托架结构包括两个墩身、桁架支撑平台、贝雷梁支撑平台和两个支撑机构，两个所述支撑机构并排布置，并一一对应设在两个墩身上，所述桁架支撑平台设在两个支撑机构上，所述贝雷梁支撑平台设在桁架支撑平台上，且贝雷梁支撑平台上设有底模板。采用预埋钢板盒及对拉预埋钢管，通过40cr对拉丝杆对拉钢牛腿在墩身两侧，在卸载件砂筒上安装钢桁架及贝雷梁构成托架结构体系，规避了三角形托架结构体系须大量高空焊接、托架数量多、成本高及吊装安全风险高等不足。
