| Abstract: | Chao He Bridge is a ground anchor suspension bridge. As the anchor boxes are the main force components, the processing precision of anchor boxes is critical control point. Anchor backing plates and load bearing plates need surface machining before assembly, and boring after assembly. In order to ensure accuracy of the coordinate and angle, the anchor box units adopt the secondary positioning technique. Continuous matching assembly, welding and test assembling start at the same time. |
