Bridge pier pile steel bar protection layer thickness control construction method
The invention provides a pier pile reinforcement protective layer thickness control construction method which comprises the following steps: S1, staking out in survey, measuring the center, side boundary and elevation of a pier body on a foundation top, and chiseling the foundation top; s2, steel reinforcement framework manufacturing, wherein steel reinforcement frameworks are machined and manufactured according to design requirements and specifications, shapes, sizes and the number specified by specifications; s3, concrete cushion blocks are installed, and circular concrete cushion blocks corresponding to the formwork are evenly assembled on the outermost layer of reinforcing steel bars of the reinforcing steel bar framework; s4, the formworks are mounted, and the formworks are assembled through lifting equipment; s5, concrete pouring and curing; according to the device, the circular concrete cushion block is clamped on the steel bar, the stability is high, the circular concrete cushion block is not prone to falling off from the steel bar when subjected to external vibration, meanwhile, when the circular concrete cushion block rotates by a certain angle, the supporting distance between the formwork and the steel bar cannot be changed, and it can be guaranteed that the thickness between the formwork and the steel bar is consistent; therefore, the thickness of the reinforcement protection layer is accurately controlled.
本发明提供一种桥墩桩钢筋保护层厚度控制施工方法，包括以下步骤：S1，测量放样，在基顶测定出墩身中心、边线及高程，并将基顶凿毛处理；S2，钢筋骨架制作，按照设计要求和规范规定的规格、形状尺寸、数量加工制作钢筋骨架；S3，混凝土垫块安装，在钢筋骨架的最外层钢筋上均匀装配与模板相对应的圆形混凝土垫块；S4，模板安装，采用起吊设备将模板进行组装；S5，混凝土灌注及养护；本发明中，圆形混凝土垫块夹装在钢筋上，稳定性较高，受到外部振动时不易从钢筋上脱落，同时圆形混凝土垫块转动一定角度时，其对模板与钢筋之间的支撑距离不会产生变化，能够保证模板与钢筋之间的厚度一致，从而精准控制钢筋保护层厚度。
