连续刚构竖向预应力钢筋施工技术

Construction Technology of Continuous Rigid-frame Vertical Prestressed Reinforcement

以贵州石阡河特大桥主桥连续刚构施工为例,介绍了墩梁固结竖向预应力钢筋张拉及压浆的具体施工方法。该方法详细介绍了张拉和压浆时具体操作步骤,对竖向预应力钢筋施工具有一定的借鉴意义。

Taking the continuous rigid-frame construction of the main bridge of Shiqian River in Guizhou as an example,the detailed construction methods of tensioning the vertical prestressed reinforcement and grouting for the consolidation of pier and beam are introduced.This method introduces the detailed operation steps of tension and grouting,which has some reference for the construction of vertical prestressed reinforcement.
