莱荣高速铁路预制箱梁冬期蒸养施工技术研究及温度控制

Study on the Steam Maintenance Construction Technology and Temperature Control of Lairong High-speed Railway Prefabricated Box Girder in Winter

高速铁路预制箱梁冬期施工具有成本高、施工难度大、温度控制难等特点。结合莱荣铁路海阳制梁场预制箱梁冬期施工的实际情况,阐述了高速铁路预制箱梁冬期施工时使用的蒸养设备、蒸养工艺及操作要点,并对蒸养温度进行了分析与总结,所取得的经验可为类似工程施工借鉴。

The high-speed railway prefabricated box girder in the winter construction is characterized by high cost,great construction difficulty,difficult temperature control.Combined with the prefabricated box girder winter construction of Lairong Railway Haiyang Beam Field,this paper introduces high-speed railway prefabricated box girder winter construction steam equipment,steam technology and operation points,and the steam temperature analysis and summary,and provides useful reference for similar engineering construction.
