Maintenance method for suspended pouring box girder in winter construction
The invention discloses a maintenance method for a suspended pouring box girder in winter construction. The maintenance method comprises the following steps that 1, an external heating heat preservation formwork is mounted; 2, an inner formwork is mounted, and to-be-poured box girder section steel bars are bound; 3, an internal heating heat preservation structure and an end heat preservation layer are mounted; 4, a temperature measuring probe is subjected to pre-burying; 5, the to-be-poured box girder section is subjected to pre-curing; 6, concrete is poured; 7, a top heat preservation layer is mounted; and 8, steam curing of the box girder section is conducted. The method is novel and reasonable in design, simple in steps, easy and convenient to construct, good in using effect and high in practical value, and the construction quality is easy to guarantee; and the external heating heat preservation formwork is mounted on the outer side of the box girder section, the top heat preservation layer is arranged on the top face of the box girder section, the end heat preservation layer is mounted on the outer side of the cross section of the cantilever end of the box girder section, the internal heating heat preservation structure is arranged inside the box girder section to heat and maintain the box girder section, the maintenance problem of the suspended pouring box girder in winter construction is solved, and application and popularization are facilitated.
本发明公开了一种悬浇箱梁冬季施工用养护方法，包括步骤：一、安装外加热保温模板；二、安装内模板并绑扎待浇筑箱梁节段钢筋；三、安装内加热保温结构和端部保温层；四、预埋测温探头；五、待浇筑箱梁节段的预养护；六、浇筑混凝土；七、安装顶部保温层；八、箱梁节段的蒸汽养护。本发明设计新颖合理，方法步骤简单、施工简便、施工质量易于保证，且使用效果好、实用价值高；通过在箱梁节段的外侧安装外加热保温模板、并在箱梁节段顶面设置顶部保温层、在箱梁节段的悬臂端的横截面外侧安装端部保温层，在箱梁节段的内部设置内加热保温结构对箱梁节段进行加热养护，解决了悬浇箱梁冬季施工的养护问题，便于推广使用。
