The invention relates to the technical field of river-crossing steel box girder construction, and aims to solve the problem that temporary supports need to be repeatedly inserted on the river surface when steel box girder sections at navigation holes are erected traditionally, buoyancy tanks are arranged at the navigation holes, the temporary supports are arranged on the buoyancy tanks, and the steel box girder sections can be temporarily supported through the temporary supports when the steel box girder sections are erected. Girder falling of the steel box girder section can be carried out by adding water into the buoyancy tank, and after girder falling of the subsequent steel box girder section is completed, the buoyancy tank sinks and drives the temporary support to be separated from the steel box girder section by continuously injecting water into the buoyancy tank, so that the buoyancy tank and the temporary support can be rapidly moved to the next navigation hole. The method has the effect of avoiding repeated insertion and hitting of temporary supports when the steel box girder sections at the navigation holes are constructed.

本申请涉及跨河钢箱梁施工的技术领域，针对传统架设通航孔处的钢箱梁节段时需要反复在河面上插打临时支架，通过在通航孔处设置浮箱并在浮箱上设置临时支架，架设钢箱梁节段可通过临时支架对钢箱梁节段进行临时支撑，往浮箱内加水便可进行钢箱梁节段的落梁，后续钢箱梁节段落梁完成后，通过继续往浮箱注入水是浮箱下沉并带动临时支架脱离钢箱梁节段便可将浮箱连同临时支架快速移动至下一通航孔处。本申请具有避免施工通航孔处的钢箱梁节段时需要反复插打临时支架的效果。
