The largest aluminum alloy bridge in China appears in Chifeng

SMM News: recently, three aluminum alloy flyovers built by Liuye Science and Technology heavy Industry were unveiled on the streets of Chifeng City, Inner Mongolia. These aluminum alloy flyovers sparkle with silver during the day and bright neon at night, becoming a beautiful scenery in Chifeng City, attracting local citizens to stop to take photos. Among them, the aluminum alloy flyover at the intersection of Chifeng Commercial Building is the largest aluminum alloy flyover with the largest scale and raw materials in China.

At present, among the six aluminum alloy flyovers built by Liuye Science and Technology heavy Industry in Chifeng City, the main bodies of three aluminum alloy flyovers located at the south gate of Hongshan City Hospital, Chifeng No. 4 Middle School and Chifeng Commercial Building have been built, and the construction has entered the final stage and is expected to be completed within one month. Among the three aluminum alloy flyovers, the aluminum alloy flyover at the intersection of Chifeng Commercial Building is the most spectacular. The bridge is a cross structure, the main frame is aluminum alloy truss design, the whole flyover aluminum alloy welding technology, all stainless steel special screws, bolt connection, the bridge length of 74 meters, span of 68 meters, height of 4.5 meters, bridge deck width of 4.5 meters, aluminum profile weight of more than 110 tons. Taking into account the different passenger flow, passenger flow and pedestrian demand, the flyover has designed four elevators and four pedestrian ladders. In addition to the corresponding bearing function, the bridge also has the characteristics of lifelong maintenance-free, including the main bridge structure and connecting screws will not rust, greatly reducing the follow-up maintenance work.

Since the start of the construction of the project, the project department has modified the design drawings many times due to the difficulty of construction, complex surrounding environment and other factors. Around the Spring Festival this year, the COVID-19 epidemic broke out, and the construction progress of the project was seriously affected. In the face of the current situation of tight construction period and heavy tasks, the project manager of Chifeng Aluminum Flyover led all the staff of the project department to meet the difficulties, overcome the difficulties, took more than a month to recover the construction period, and completed the construction node task of the project two days ahead of schedule, which was highly appraised by the owner.

The connection of the three aluminum flyovers will greatly alleviate the pressure of traffic congestion in the central city of Chifeng and solve the problem of citizens' safe travel. It is reported that the other three aluminum alloy flyovers built by Liuye Science and Technology heavy Industry in Chifeng City are also under intensive construction and are expected to be completed by the end of this year.
