摘要
合龙段施工是连续刚构桥挂篮悬臂浇筑施工的关键环节。以重庆市轨道交通3号线嘉陵江特大桥为背景,详细介绍了桥梁合龙温度、时间、顶推力的确定,以及中跨顶推合龙段施工情况;采取设置劲性骨架及顶推的措施,不但较好地解决了连续刚构桥高温合龙的难题,而且对非对称连续梁两端及墩身无任何质量、线形的影响。
Based on moving project of Children Palace in Mentougou District of Beijing City,the authors analyze the selection reasons of cylinder formwork of retaining wall, construction difficulties, construction process and so on,put forward the scheme of wood formwork. The authors introduce manufacture process and construction technology of wood formwork in detail. The project can meet the requirements of irregular formwork,economic and social practice shows that wood formwork benefits are obtained.
