连续刚构箱梁挂篮施工技术

连续刚构箱梁挂篮施工技术探索

摘要： 随着连续刚构桥梁施工技术逐渐比较熟练，但施工过程中同样会忽视某些重要工序的施工质量；通过结合某连续刚构桥梁挂篮悬臂现浇施工实例，提出其在施工过程中重点施工工序，如主桥挂篮施工的质量控制技术措施等，提出了相关的对策。 关 键 词：连续刚构 箱梁施工 挂篮施工 挂篮拼装 中图分类号： u448 文献标识码：a 文章编号：

abstract：along with the continuous rigid frame bridge construction technology gradually more skilled, but the construction process also will ignore some important process of the construction quality; through a combination of a continuous rigid frame bridge hanging basket cantilever cast-in-place construction examples, puts forward the key construction process in the construction process, such as the main bridge hanging basket construction quality control measures, put forward relevant countermeasures.

key words：continuous rigid frame; box girder construction; hanging basket construction; hanging basket 1引言

某主桥上部结构采用(73+125+73)m pc 连续刚构，共分为 19 种梁段。其中 0~2#梁段为立托架现浇，3~17#梁段采用挂篮悬臂现浇施工，18#梁段为合龙段，19#梁段为边跨现浇段。箱梁纵向分块为
