锡溧漕河改线特大桥悬臂现浇箱梁施工技术应用

Application of Cantilever Cast-in-place Box Girder Construction Technology for the Xilicao River Reroute Super Large Bridge

工程建设中为跨越河道、沟谷,大跨度悬臂现浇箱梁桥梁逐渐增多。本文以锡溧漕河改线特大桥第4联(左幅76+115+74m、右幅66+115+68m)悬臂现浇箱梁为例介绍采用挂篮做支架施工悬臂现浇箱梁的施工方法,达到了提高工效、节约成本和降低安全风险的目的,对类似工程施工具有借鉴意义。

In engineering construction,large-span cantilever cast-in-place box girder bridges are gradually increasing to cross rivers and valleys.This article takes the fourth section(left section 76+115+74m,right section 66+115+68m)of the Xilicao River Diversion Extra Large Bridge as an example to introduce the construction method of using hanging baskets as supports to construct cantilever cast-in-place box beams.This achieves the goal of improving work efficiency,saving costs,and reducing safety risks,and has reference significance for similar engineering construction.
