弧形钢筋弯曲设备改制后的成功应用

The successful application of arc concrete-bar bending machine reforming

结合三峡永久船闸地下输水系统工程和湖北清江水布垭工程地下厂房工程的特点及施工难题,介绍了弧形弯曲机的改进设计与制作方法,阐述了弧形机工作原理,并对其进行受力分析和强度验算,提出了施工过程中的注意事项。

Combined with the characteristics and construction difficult of Three Gorges permanent lock underground water transmission system engineering and Hubei Qingjiang Shuibuya engineering underground factory engineering,the improved design and fabrication method of arc bending machine were introduced,the arc machine working mechanism was illustrated,its stress analysis and strength checking calculation were carried out,and the matters need attention in construction process were proposed.
