大型钢筋混凝土拱涵施工技术研究

Study on construction technologies of large-scale steel reinforced concrete arch culvert

以和榆高速公路拱涵工程为例,介绍了拱涵基础施工技术要点,并从内拱支架搭设、拱圈模板安装、钢筋安装、拱圈混凝土浇筑、养生等方面,阐述了拱圈施工措施,旨在避免拱圈开裂现象的发生。

Taking He-Yu highway culvert engineering as an example,the paper introduces arch culvert foundation construction technology points.Starting from aspects of internal arch support erection,arch ring template installation,steel installation,arch ring concrete grouting and maintenance,it describes the arch ring construction measures,with a view to avoid arch ring cracking phenomenon.
