小半径曲线架梁施工方法分析

Discussion on the Construction Method of Small Radius Curved Frame Beams

架桥机通过改进设计,加大下导梁横移量,后支腿加宽,后支腿台车调速等方法,适应小曲线。简支式架桥机机身短,在架设小曲线箱梁时具有先天的优越性。

The bridge erecting machine adapts to the small curve by improving the design, increasing the transverse displacement of the lower guide beam, widening the rear leg, regulating the speed of the rear leg trolley, etc. The fuselage of simply supported bridge erecting machine is short, and it has innate advantages in erecting small curved box girder.
