Erecting and dismantling method of construction platform for widening and reconstructing bridge
The invention provides an erecting and dismantling method for a construction platform for widening and reconstructing a bridge, and belongs to the technical field of bridge construction. The technical problem that in the construction process of assembly welding and the like at the joint of the middle beam sections, the middle beam sections are suspended in the middle and cannot reach the middle construction position through the outer side of the bridge floor is solved. According to the technical scheme, the erecting method of the construction platform for widening and reconstructing the bridge comprises the following steps that S1, a truss beam section construction platform is erected, S2, a box beam section construction platform is erected, and S3, a transition beam section construction platform is erected. The dismantling method comprises the following steps that 1, the truss girder section construction platform is dismantled; the construction method has the beneficial effects that the problem that a bridge inspection vehicle cannot be lifted into the middle of a bridge is solved, meanwhile, multi-interface and multi-process construction can be met, and the construction method is firm and good in stability.
本发明提供了一种拓宽改建桥梁的施工平台的搭设及拆除方法，属于桥梁施工技术领域。解决了中幅梁段连接处进行装配焊接等施工过程，因中幅梁段悬空在中间，无法通过桥面外侧到达中间的施工位置的技术问题。其技术方案为：一种拓宽改建桥梁的施工平台的搭设方法，包括如下步骤：S1：桁架梁段施工平台的搭设，S2：箱型梁段施工平台的搭设，S3：过渡梁段施工平台的搭设；拆除方法，包括如下步骤：1：桁架梁段施工平台的拆除；2：箱型梁段施工平台的拆除，3：过渡梁段施工平台的拆除，本发明的有益效果为：解决了桥检车无法升入桥中间的问题，同时可以满足多界面多工序施工，且结实牢固，稳定性好。
