The Fabrication of Flat Steel Strobe with Curved Steel Tube Truss

Located on the intersection of Cao’e river and Qiantang river, the strobe of Cao’e River, which can intercept tide and discharge flood, is made of curved steel tube truss. This kind strobe is used first time in China. It has the characteristics of light weight, high stiffness and saving steel. It can be lifted easily because the sedimentation of tide soil and sand has little affect on its operation. The truss can reduce the impulse of tide to the strobe surface. The method and the procedures on how to control the quality of the huge steel strobe is presented.
