大跨度连续梁挂篮悬臂浇筑冬季施工技术

Construction technology in winter of hanging basket cantilever pouring of long span continuous beam

为确保魏家湾跨同三高速公路特大桥冬季施工顺利进行,介绍了一种聚氨酯泡沫保温加蒸汽暖棚的冬季施工技术与措施,通过实施获得了良好的保温效果,保障了大跨度连续梁冬季悬臂施工质量,可为今后类似施工提供借鉴。

In order to ensure the smooth construction of Weijiawan Bridge crossing Tongjiang-Sanya conventional expressway in winter,a winter construction technology combined with polyurethane foam insulation and steam heating and its measures were introduced.Good heat insulation was achieved by using the measures,and the quality of cantilever construction of large-span continuous beam in winter was guaranteed,which provided reference for similar construction in the future.
