襄阳汉江五桥引桥、匝道桥上部结构均为支架现浇箱梁,大部分位于水上。在以往类似工程,一般采用大型钢管桩排架作为箱梁现浇支架。为提高材料周转率,便于支架拆除,汉江五桥水上引桥箱梁采用钢管桩平台与满堂支架组合的形式进行施工。 Yangyang Hanjiang five bridge approach bridge, ramp bridge superstructure are cast-in-place box girder, most are located on the water. In the past similar projects, the general use of large steel pipe pile rack as a cast-in-place box girder. In order to improve the turnover rate of materials and facilitate the dismantling of the supports, the construction of the waterway bridge box girder of the fifth bridge on the Hanjiang River is carried out by the combination of steel pipe pile platforms and full support.
