Multi-point pushing system for large-span steel box girder of overpass existing high-speed line ramp bridge and construction method
The invention relates to a multi-point incremental launching system for a large-span steel box girder of an overpass existing line ramp bridge and a construction method. The construction method comprises the following construction steps: step 1, constructing a lower structure of the bridge; secondly, a temporary support is erected; step 3, pre-pressing the temporary bracket; 4, steel box girder splicing is conducted, specifically, a steel box girder splicing platform is installed, and the steel box girders are spliced through the steel box girder splicing platform; 5, reinforcing the steel box girder; and sixthly, the steel box girder is pushed. The invention belongs to the field of civil engineering, and relates to a construction method for a large-span steel box girder of an overpass existing line ramp bridge, which effectively reduces the engineering cost, accelerates the construction speed, and can obtain better technical and economic benefits when being applied to actual engineering.
本发明涉及上跨高速既有线匝道桥大跨径钢箱梁多点顶推体系及施工方法，施工步骤包括：步骤一、桥梁下部结构施工；步骤二、临时支架搭设；步骤三、临时支架预压；步骤四、钢箱梁拼装：安装钢箱梁拼装平台并通过钢箱梁拼装平台对钢箱梁进行拼装；步骤五、钢箱梁加强处理；步骤六、钢箱梁顶推。本发明属于土木工程领域，针对上跨高速既有线匝道桥大跨径钢箱梁的施工方法，有效降低工程成本，加快施工速度，应用于实际工程中可取得较好的技术经济效益。
