公路工程软土地基现浇箱梁支架施工技术

The cast-in-place box girder bracket construction technology of highway engineering soft soil foundation

以某大桥高沟互通主线桥D匝道20×4 m变截面连续箱梁现浇施工为例,针对软土地基现浇箱梁支架施工方案进行了研究比选,详细介绍了抱箍+贝雷梁组合式支撑体系及施工工艺,并总结了施工中的注意要点,以供同类工程参考。

Taking 20 ×4 m variable section continuous box beam cast-in-place construction of a bridge Gaogou interflow main bridge ramp D as an example, this paper made research and comparison selection to the construction scheme of soft soil foundation cast-in-place box girder bracket, introduced in detail the hoop ＋ Bailey beam combined support system and construction process, and summarized the key points should pay attention in construction, so as to provide references for similar engineering.
