    摘要:

    经过现场实地勘查发现,上海中环高架桥梁支座出现了各式各样的病害问题。如果放任桥梁支座病害进一步发展,可能会影响到车辆安全通行。为了解决桥梁结构的安全隐患问题,提出利用500 t三连杆超薄千斤顶单墩顶升技术快速更换病害支座。此法更能适应中环高架上垫石至墩顶净空低、墩顶千斤顶布置面狭小、顶升力需求大等特点,且可以有效节约成本,对原桥结构损伤,乃至交通组织影响降到最低。

    Abstract:

    With the rapid development of economy and society, the society has put forward higher requirements for the construction of bridges in central urban areas, especially in terms of landscape coordination, environmental protection and construction efficiency. The conventional bracket construction methods have been difficult to meet the requirements, and it is necessary to research and develop a construction technology with higher efficiency, environmental performance and better landscape performance. The socket-type disc-buckle steel pipe scaffold has the advantages of high rigidity, high strength, good landscape and environmental protection performance, and is the direction of the future development of the scaffold construction in the central urban areas. Based on the main line elevated bridge project in Puzhou Road of Pukou District in Nanjing, the construction technique and technology of the socket-type disc-buckle steel pipe scaffold in the central urban area are studied.
