Construction method for assembling and integrally sliding main bridge steel structure segments under full-length track
The invention discloses a construction method for assembling and integrally sliding main bridge steel structure sections under a full-length track. The construction method comprises the following steps that firstly, all the main bridge steel structure sections are prefabricated; secondly, a temporary supporting system is built on a construction site; thirdly, transverse limiting devices are arranged on the two sides of the sliding rail; fourthly, splicing of the single-span main bridge steel structure is completed on the temporary supporting system close to the first main pier through a splicing-sliding scheme; fifthly, the single-span main bridge steel structure assembled in the fourth step integrally slides in place on the temporary supporting system; and sixthly, the single-span main bridge steel structure integrally sliding in place in the fifth step is subjected to beam falling. Therefore, a novel bridge construction scheme is provided, and the main bridge steel structure construction which cannot adopt a land transportation support method and pursues construction economy is achieved.
本发明公开了一种通长轨道下主桥钢结构节段拼装整体滑移施工方法，包括如下步骤：步骤一、预制各主桥钢结构节段；步骤二、在施工现场搭建临时支承体系；步骤三、在滑移轨道两侧布置横向限位装置；步骤四、在靠近第一主墩的临时支承体系上采用拼装‑滑移方案完成单跨主桥钢结构的拼装；步骤五、将步骤四拼装好的单跨主桥钢结构在临时支承体系上整体滑移到位；步骤六、将步骤五整体滑移到位的单跨主桥钢结构落梁。因此，本发明提供一种桥梁施工新方案，解决不能采用陆运支架法又追求施工经济性的主桥钢结构施工。
