浅谈装配式预应力混凝土连续箱梁施工

On prefabricated prestressed concrete continuous box girder construction

以108国道介霍改建公路三湾口大桥工程为例,对预应力混凝土连续箱梁预制的施工技术进行了介绍,从原材料、混凝土浇筑、梁体养护等方面具体阐述了施工工艺,对同类预应力混凝土箱梁预制施工具有指导意义。

Taking Sanwankou Bridge project in 108 national road from Jiexiu to Huozhou as an example,the paper introduces the construction technique of the prestressed concrete continuous box girder,and illustrates the construction craft from the raw materials,concrete grouting and maintenance of beam,so as to have the directive significance for similar prestressed concrete box girder construction.
