Steel truss girder guide beam lifting and mounting process
The invention relates to the technical field of bridge construction, in particular to a steel truss girder guide beam lifting and mounting process which comprises the following steps: mounting beam lifting stations on T beams at the tops of a first pier and a second pier, mounting a beam splicing bracket at the top of the second pier, mounting a lifting portal frame at the top of a third pier, splicing a guide beam section B between the bottoms of the second pier and the third pier, and mounting a steel truss girder guide beam section B between the bottoms of the second pier and the third pier. A guide beam section A is assembled on the pier top of the third pier; the beam lifting station and the lifting portal frame synchronously lift the guide beam section B to the beam splicing bracket, and the guide beam section B and the guide beam section A at the top of the third pier are connected into a whole; and the first section of steel truss girder is connected with the tail of the guide beam on the beam splicing bracket, and installation is completed. By arranging the beam splicing bracket, the guide beam is directly lifted to the beam splicing bracket from the position between the piers to be installed, long-distance pushing is not needed, the construction process is simplified, the construction period is shortened, the construction cost is reduced, and the problems that the existing guide beam installing, hoisting and pushing distance is long, the construction process is complex, and a large amount of manpower and material resources need to be consumed are solved.
本发明涉及桥梁施工技术领域,尤其涉及一种钢桁梁导梁提升安装工艺,包括如下步骤:在一号墩和二号墩墩顶T梁上安装提梁站,在二号墩墩顶安装拼梁托架,在三号墩墩顶安装提升门架,在二号墩和三号墩墩底中间拼装导梁B节段,在三号墩墩顶拼装导梁A节段;提梁站和提升门架同步提升导梁B节段至拼梁托架,并与三号墩墩顶导梁A节段连接成整体;将第一节段钢桁梁并与拼梁托架上的导梁尾部连接,安装完成。本发明通过设置拼梁托架,直接将导梁从桥墩之间提升至拼梁托架上安装,无需长距离顶推,简化了施工过程,缩短了施工周期,降低了施工成本,解决了现有导梁安装吊装和顶推距离长,施工过程复杂,需要耗费大量人力物力的问题。
