Novel high-speed rail bridge pier top coaming construction method
The invention provides a novel high-speed railway bridge pier top coaming construction method. The novel high-speed railway bridge pier top coaming construction method comprises the following steps that S1, after a bearing platform is poured and reaches preset strength, the top face of the bearing platform is cleaned; s2, scabbling the top surface of the bearing platform, and binding a reinforcement cage corresponding to the pier body; s3, a pier body formwork is installed, and after the pier body formwork is installed, a top cap and a steel reinforcement framework corresponding to a pier top coaming are bound; s4, a top cap bottom die and a coaming template are mounted, and the pier body, the top cap, the supporting padstone and the pier top coaming are integrally poured; and S5, expansion joint construction is conducted on the pier top coaming. By means of pier top coaming construction, the problem of traditional hanging fences is thoroughly solved, lower components of a bridge can be constructed more quickly and efficiently, and many quality diseases caused by traditional technologies are avoided. And the concrete fence is arranged on the outer side of the top cap, so that potential safety hazards in later maintenance are reduced on the premise that various functions required by the structure are not changed.
本发明提供一种新型高铁桥梁墩墩顶围板施工方法，包括以下步骤：步骤S1，在承台浇筑完成并达到预设强度后对承台进行顶面清理；步骤S2，对承台顶面进行凿毛处理后对墩体对应的钢筋骨架进行绑扎；步骤S3，安装墩体模板，在墩体模板安装完成后绑扎顶帽及墩顶围板对应的钢筋骨架；步骤S4，安装顶帽底模和围板模板，对墩体、顶帽、支承垫石及墩顶围板进行一体化浇筑；步骤S5，对墩顶围板的伸缩缝施工。墩顶围板施工彻底解决了传统吊围栏的难题，并能够更快速高效的施工完桥梁下部构件，避免了许多因为传统工艺所带来的质量病害。以供检修人员进行检修，在顶帽外侧设有混凝土围栏，在不改变结构所需要的各项功能的前提下，降低了后期养护中的安全隐患。
