深水承台上连续刚构桥0号块施工技术方案研究

Start Element Supporting Placement Construction Technology of Continuous Rigid Frame Bridge Using by Large Diameter Steel Tubes on Abutment

在全部预应力混凝土连续箱梁施工中,0号块的施工极为关键,其施工质量决定着整个连续梁施工的成败。结合工程实例,介绍了连续刚构桥在承台上架设粗钢管支架及碗扣式满膛脚手架的施工工艺,为其他类似工程提供参考。

Start element construction is a key and important process of continuous rigid frame bridge, so the start element directly determines the bridge construction qunlity. Combined with practice, the technology of large diameter under water steel tubes on abutment with section steel platform and full bore scaffolding is introduced, it provide reference for other similar project.
