Steel arch bridge arched girder synchronous pushing and asynchronous installation construction method
The invention relates to a synchronous pushing and asynchronous mounting construction method for arched beams of a steel arch bridge, which comprises the following steps of: after a pushing bracket is erected, sequentially hoisting steel beam sections on the pushing bracket on one bank and pushing the steel beam sections to the other bank, and flatly placing each arch rib section on the corresponding steel beam section and moving the arch rib sections along with the steel beam sections; after all the steel beam sections are pushed in place, the steel beam sections are connected, then an arch rib installation support is erected on the bridge, and an automobile crane goes onto the bridge to hoist arch ribs section by section. Compared with an existing beam-first arch crown pushing method, the working procedure that a transport vehicle transports an arch to a bridge is omitted, and the construction efficiency is improved; compared with an existing integral pushing method, the pushing height and weight are low, and the construction safety can be improved.
本发明涉及一种钢拱桥拱梁同步顶推异步安装施工方法，顶推支架搭设完成后，在一岸将钢梁节段依次吊放到顶推支架上向另一岸顶推，同时将各拱肋节段平放在对应的钢梁节段上，随钢梁节段一起移动；钢梁节段全部顶推到位后，进行钢梁节段间的连接，然后在桥上搭设拱肋安装支架，汽车吊上桥逐段吊装拱肋。本发明与现有先梁后拱顶推法相比，节省了运输车运拱上桥工序，提高了施工效率；与现有整体顶推法相比，顶推高度和重量较低，可提高施工安全性。
