One-time pouring method for variable cross-section bridge pier column
The invention relates to the technical field of pier column construction, in particular to a variable cross-section bridge pier column one-time pouring method which comprises the steps that S1, a bearing platform is constructed, specifically, the bearing platform is constructed at the designated position of a construction site; s2, pier column steel bar binding, wherein pier column steel bars are bound according to the measurement result after pier column center measurement lofting; s3, forming formwork assembling, wherein forming formworks are assembled on the outer sides of the pier column steel bars, and a pouring cavity is defined; s4, force bearing outer plate fixing is conducted, specifically, the force bearing outer plate is fixed to the peripheral side of the forming template, and a containing cavity is formed between the force bearing outer plate and the forming template; concrete is injected into the pouring cavity and vibrated, meanwhile, a water bag is placed in the containing cavity, water is injected into the water bag, and the upper surface of the concrete is controlled to be flush with the liquid level in the water bag; s5, water drainage and formwork removal are conducted, specifically, water in the water bags is emptied after concrete is solidified, and the force bearing outer plate and the forming formwork are removed in sequence; the construction method has the effects that the construction period of the pier column is shortened, and the safety of the formwork structure in the construction process is guaranteed.
本申请涉及墩柱施工技术领域，尤其涉及一种变截面桥梁墩柱一次性浇筑方法，包括S1：承台施作：在施工现场指定位置进行承台施工；S2：墩柱钢筋绑扎：墩柱中心测量放样后根据测量结果绑扎墩柱钢筋；S3：成型模板组装：在墩柱钢筋外侧组装成型模板，围成浇筑腔；S4：承力外板固定：将承力外板固定于成型模板外周侧，承力外板和成型模板之间形成放置腔；S5：浇筑、注水：向浇筑腔内注入混凝土并振捣，同时，在放置腔中放入水袋，并向水袋中注水，控制混凝土上表面和水袋内液面持平；S5：排水拆模：混凝土凝固后排空水袋中的水，并先后将承力外板和成型模板拆除；本申请具有缩短墩柱的施工周期并保障施工过程中模板结构的安全性的效果。
