摘要
河耳沟特大桥主桥桥型为连续刚构,其上部结构的纵向预应力束采用22j15.24钢绞线束,其中最长的预应力束长度达210 m,介绍其预应力束真空辅助压浆施工工艺,供同类型施工参考。
The main bridge of Heergou Bridge is designed as a continuous rigid-frame structure. In the superstructure of the bridge, the longitudinal prestressing strands 22φ15. 24 are used, of whichthe longest strand is up to 210 m. In this paper, the construction technology for vacuum grouting of the strands is presented. It is expected that the technology provided herewith may serve as reference to the construction of similar kind.
