Bridge padstone prefabrication and installation construction method
The invention discloses a bridge padstone prefabrication and installation construction method which comprises the following steps: firstly, making construction preparation and completing processing of padstone reinforcing meshes, then adjusting a cross slope, polishing a template, brushing a release agent, completing template assembly, then measuring the elevation of the template, then installing the reinforcing meshes, pre-burying support bolt holes and hoisting holes, and finally assembling the template. Concrete pouring of the cushion stone is completed, then formwork removal and maintenance are conducted, numbering, overturning and scabbling treatment is conducted on the cushion stone, scabbling and cleaning are conducted on the combined face of the cover beam and the cushion stone, axis ink lines of the cover beam and the cushion stone are popped out, then a leveling steel cushion block and a slurry blocking formwork are sequentially installed, the cushion stone is pre-installed, and the cover beam and the cushion stone are pre-installed. Checking the height difference of the four corners and the center of the padstone; according to the method, the engineering quality is improved, industrial production of the padstone is achieved, the workload of workers is reduced, the environment is protected, the construction efficiency is improved, the construction period is shortened, the safety risk of constructors is reduced, and the method is suitable for being widely popularized and used.
本发明公开了一种桥梁垫石预制及安装施工方法，首先做施工准备并完成垫石钢筋网片的加工，再对横坡进行调整并将模板打磨并刷脱模剂，完成模板拼装，接着对模板进行标高测量，再将钢筋网片安装，并将支座螺栓孔及吊装孔预埋，完成垫石的混凝土浇筑，随后进行拆模和养护，再对垫石进行编号、翻转和凿毛处理，然后对盖梁顶垫石结合面进行凿毛和清理并弹出盖梁及垫石轴线墨线，再依次安装调平钢垫块和挡浆模板，并进行垫石预安装，紧接着对垫石四角及中心高差校核；本发明提高了工程质量并实现了垫石的工业化生产，还降低了工作人员的工作负担并保护了环境，也提高施工效率以及缩短了施工工期，降低了施工人员的安全风险，适合被广泛推广和使用。
