钢导梁配合汽车吊梁板安装施工技术

Construction Technology of Installation of Bridge Beam by Steel launching nose and hydraulic cranes

在城市道路桥梁施工过程中,梁板安装是桥梁上部结构施工的重要工序。由于工地现场自然条件的限制,仅仅采用汽车吊进行梁板安装,常常不能满足施工要求。结合国内相关工程实践,深入探讨钢导梁配合汽车吊桥吊装梁板技术的施工工艺、施工流程和注意事项,可为同类施工提供借鉴。

In the construction process of urban road and bridge,the installation of bridge beam is an important procedure of bridge superstructure construction. Because of the limitation of natural conditions in the construction site,it s hard to satisfied with the construction request when we install the beam just by the hydraulic cranes. Combined with the relevant engineering practice in China,the paper discusses the construction technology and safety problems of the installation of bridge beam by steel launching nose and hydraulic cranes.The discussion can provide reference for the similar project.
