Construction method for externally wrapping concrete on arch ring of stiff skeleton concrete arch bridge
The invention discloses a stiff skeleton concrete arch bridge arch ring encased concrete construction method, which comprises the following steps: assembling a skeleton unit and a template system, constructing an arch ring skeleton, installing the template system and pouring encased concrete: installing a bottom die platform at the bottom of the skeleton unit, arranging two side templates on the surface of the bottom die platform, the two side formworks are located on the two outer sides of the framework unit respectively, and gaps between the side formworks and the framework unit serve as safety channels. The method comprises the following steps: firstly, completing arch springing solid section construction, then carrying out synchronous hoisting construction on framework units from two arch springing positions of an arch ring, and completing closure construction at an arch crown position; connecting limitation between the side formworks and the bottom formwork platform is removed, and the side formworks are installed on the side faces of the framework units; the method has the effects of improving the framework splicing efficiency and improving the construction safety.
本申请公开了一种劲性骨架混凝土拱桥拱圈外包混凝土施工方法，组装骨架单元与模板体系、拱圈骨架施工、模板系统安装以及浇筑外包混凝土：将底模平台安装在骨架单元底部，将两块侧模板设置在底模平台表面，两块侧模板分别位于骨架单元两外侧，侧模板与骨架单元之间的空隙作为安全通道；先完成拱脚实体段施工，然后从拱圈的两处拱脚位置进行骨架单元同步吊装施工，并在拱顶位置完成合拢施工；拆除侧模板与底模平台之间的连接限制，将侧模板安装在骨架单元侧面；本申请具有提高骨架拼装效率以及提高施工安全性的效果。
