| Abstract: | The Yellow River Bridge, the main arch span of which is 360 m, has the No.1 span among the same structures in China. The design and construction of this bridge＇ s large-tonnage and large-span cable crane, the processing and installation, the control of steel tube arch bridge line-type and the large-diameter concrete jacking-up construction have higher scientific and technological content. This paper probes into the construction technology of pouring C50 compensating non-shrinkage concrete into steel tube arch. |
