双上导梁步履式架桥机是先进的桥梁架设施工设备 ,在架设弯桥时 ,受桥墩台长度及架桥机主梁间净空限制 ,纵向梁的长度受到限制甚至无法施工。本文介绍了LG - 90 0型弯桥架桥机结构特点和采用的预制砼节块拼装架桥工艺 ,并论述其优点及结构特点
The double upper beam walking type bridge erecting machine is an advanced bridge erecting construction equipment. When erection of the curved bridge, the length of the bridge piers and the clearance between the main girder of the erecting machine are limited, and the length of the longitudinal beam is limited or even impossible to construct. This paper introduces the structural features of the LG - 90 0 Bending Bridge Erecting Machine and the prefabricated concrete section assembled erecting process, and discusses its advantages and structural features
