Cast-in-place box girder construction method
The invention discloses a cast-in-place box girder construction method, and particularly relates to a cast-in-place box girder construction technology adopting a socket type disc buckle type supporting frame. The method comprises the steps of foundation treatment, support erecting, support pre-pressing, formwork manufacturing and mounting, steel bar machining and mounting, prestressed tendon construction, support mounting, concrete pouring and maintenance, formwork and support dismounting and the like. And through fine foundation treatment and a high-adjustability support system, the stability and safety of construction are ensured. Formwork manufacturing and mounting are accurate, and steel bar and prestressed tendon construction is strictly carried out according to design requirements. The concrete pouring and curing process is optimized, and the concrete quality is ensured. The method improves the construction efficiency and quality of the cast-in-place box girder, and is particularly suitable for large-span and complex-terrain bridge construction.
本发明公开了一种现浇箱梁施工方法，特别是采用承插型盘扣式支撑架的现浇箱梁施工技术。该方法包括地基处理、支架搭设、支架预压、模板制作及安装、钢筋的加工及安装、预应力筋施工、支座安装、混凝土浇筑及养护、模板和支架的拆除等步骤。通过精细的地基处理和可调节性高的支架系统，确保施工的稳定性和安全性。模板制作和安装精确，钢筋及预应力筋施工严格按照设计要求进行。混凝土浇筑及养护过程优化，确保混凝土质量。该方法提高了现浇箱梁施工的效率和质量，尤其适用于大跨度和复杂地形的桥梁建设。
