摘　　要：传统的沉井建造采用现浇混凝土技术,将钢筋逐根运送到安装位置,逐根绑扎成型,再立模浇筑混凝土,钢筋逐根绑扎方式速度慢,特别是高空作业状态效率更低;沉井为竖向结构,钢筋竖向绑扎存在刚度不足的问题,钢筋位置容易偏斜,造成保护层不符合要求、钢筋骨架不牢靠等问题,影响工程质量和施工安全;通过实施钢筋模块化工艺,形成了沉井钢筋模块工厂加工、现场安装模式,实现质量和效率双提升,有效控制安全风险,逐步形成了钢筋加工的工业化。Traditional construction methods for reinforced concrete wells involve the use of cast-in-place concrete technology,where steel bars are individually transported to the installation location and tied one by one before pouring concrete.However,this method of individually tying steel bars is slow,especially under high-altitude working conditions,resulting in lower efficiency.Additionally,the vertical binding of steel bars in reinforced concrete wells often lacks stiffness,leading to issues such as misalignment of steel bar positions,inadequate protective layers,and unstable steel bar skeletons,which can affect the quality and safety of the construction project.To address these challenges,the implementation of steel bar modularization technology has been introduced,which involves factory processing of reinforced concrete well modules and on-site installation.This approach has resulted in improvements in both quality and efficiency,effectively controlling safety risks,and gradually achieving industrialization in steel bar processing.
