Steel-concrete continuous beam bridge construction process of walking type pushing steel box beam
The invention relates to a steel-concrete continuous beam bridge construction technology of a walking type pushing steel box beam. The steel-concrete continuous beam bridge construction technology comprises the following steps that S1, a temporary pier platform is erected; s2, pushing equipment debugging, wherein a hydraulic pushing device is debugged in a pre-pressing mode; s3, guide beam assembly, wherein steel profiles are spliced on the temporary pier platform section by section to form a guide beam; s4, assembling the steel box girder; s5, mounting a back supporting truss; and S6, pushing is conducted, specifically, a hydraulic pushing device is adopted for pushing the steel box girder of the initial section and the guide girder, after pushing is completed, the steel box girder of the next section is assembled at the end, away from the guide girder, of the steel box girder, then the steps of pushing and assembling the steel box girder are repeated, the front end of the guide girder is in lap joint with the tail end construction platform, and finally the guide girder and the back supporting truss are dismantled. The steel box girder at the construction tail end is assembled and installed on the tail end construction platform; and S7, pouring. On the premise of not influencing the use of the existing road, the influence of overlarge deflection of the guide beam on the installation can be reduced.
本申请涉及一种步履式顶推钢箱梁的钢‑混连续梁桥施工工艺，其包括以下步骤：S1、临时墩平台搭设；S2、顶推设备调试：采用预压的方式调试液压顶推器；S3、导梁拼装：采用钢型材在临时墩平台分节拼装形成导梁；S4、钢箱梁拼装；S5、背撑桁架安装；S6、顶推：采用液压顶推器顶推初始段的钢箱梁以及导梁，并在顶推完成后，在钢箱梁背离导梁的一端拼装完成下一节段的钢箱梁，然后重复顶推及拼装钢箱梁的步骤，使得导梁的前端搭接于末端施工平台，最后拆除导梁和背撑桁架，并在末端施工平台完成施工末端的钢箱梁的组装和安装；S7、浇筑。本申请能够在不影响既有道路的使用前提下，减小导梁挠度过大对于安装的影响。
