防撞墙与小箱梁一体预制构件安装关键技术

Key Technologies for Installation of Integrated Precast Components of Anti-collision Walland Small Box Girder

以上海S3公路主线施工1标为例对防撞墙与小箱梁一体预制构件安装施工技术进行了研究。针对防撞墙与小箱梁一体预制构件与常规预制小箱梁构件的区别,采取了对应的施工技术,并阐述了施工过程中的控制要点,以期为类似工程施工提供一定的参考。

Taking Shanghai S3 Highway Main Line Construction Bid 1 as an example,this paper studies the installation and construction technology of anti-collision wall and small box girder integrated precast components.According to the differences between anti-collision wall and small box girder integral precast component and conventional prefabricated small box girder component,the paper adopts corresponding construction technology,and illustrates the control points in the construction process,so as to provide a certain reference for similar engineering construction.
