后张预应力连续箱梁整体一次浇筑施工工艺

Construction Technology of One Monolithic Concreting to Post-tensioned Prestressed Continuous Box Girder

依托南水北调中线干线跨渠桥梁中宅阳北桥工程,通过方案比选,采用预先设计、安装箱梁内模的方法调整施工工艺,严格施工过程质量控制,确保了预应力连续箱梁整体一次浇筑施工,该工艺不仅加快了施工进度,而且提高了连续箱梁的整体性,可作为桥梁建设同行们的参考。

relying on Zhongzhaiyang North Bridge engineering in the main bridge across the canal of the South-to-North Water Transfer Project, through scheme comparison, adopt the method of designing and installing box girder internal model in advance to adjust the construction technology, strict quality control in construction process and ensure the construction of one monolithic concreting a cast-in-place prestressed continuous box girder. The process not only speeds up the construction progress, and improving the integrity of the continuous box girder, which can be taken as reference to the peers in the bridge construction.
