太榆路改线工程钢箱梁施工探讨

Taiyu road line modification project technical summary

太榆路改线工程的车站南街定向匝道桥采用全焊接钢箱梁结构,钢箱梁的制造工艺、焊接质量是关键,指出钢箱梁的制造及业主方要把握钢箱梁制造中分段制造方案、焊接工艺评定、首节段验收等几个关键环节,并委托第三方检测机构对焊缝内在质量、防腐涂层漆膜厚度进行检测,委托监理单位把好原材复检、焊接工艺评定、节段验收、出厂质量验收关等。

The South Street Orienteering ramp bridge of Taiyu Road transformation engineering adopted the manufacturing process of fully welded steel box girder structure,steel box girder,the key was the welding quality. This paper pointed out that the manufacture and the owner of steel box girder should grasp the subsection manufacturing scheme,welding process evaluation,first stage acceptance and several key links in steel box girder manufacturing,and entrusted the third party inspection organization tested the quality,anti-corrosion coating film thickness inner welding seam,the entrusted supervision unit should check the raw materials reinspection,welding process evaluation,section acceptance,outgoing quality acceptance and so on.
