　　The traditional bridge project basically uses steel as the main construction material, which is plagued by the durability problem caused by its poor corrosion resistance . The application and development of the aluminum flyover as a new type of aluminum alloy material have important theory and development for the development of modern bridge engineering. Practical significance.

　　The main characteristics of the aluminum alloy flyover can be summarized in three words-"high, light and bright". "High" refers to the high-tech content of the aluminum alloy pedestrian bridge; "light" refers to the aluminum alloy pedestrian bridge with light structure and light weight; "bright" refers to the visual perception of the aluminum alloy pedestrian bridge. The "high, light and bright" aluminum alloy pedestrian bridge not only meets the needs of convenient traffic in the city, but also reflects the technology and landscape of a city to a certain extent.

　　The characteristics of all aluminum alloy flyover:

　　(1) Corrosion resistance, long service life, and low maintenance cost: aluminum alloy can form an oxide film under natural conditions, protect the internal materials, has good corrosion resistance, and does not require surface coating protection, so it has a high service Long life and low maintenance costs.

　　(2) Green environmental protection, high recovery rate: aluminum alloy recovery energy consumption is only 5% of electrolytic aluminum, and the recycling rate is large, and the recovery rate can reach more than 90% (more than 5 times the steel recovery rate), basically and aluminum The price of ingots is not much different, and it is a typical green material.

　　(3) Safe and durable, easy to install: the windproof and shockproof factors are taken into account in the design of the building structure, aluminum alloy can be formed by extrusion processing to avoid the reduction of fatigue strength caused by welding, and the local wall thickness can be increased to improve the overall bridge Carrying capacity.

　　(4) Factory production, off-site assembly, shortened lifting time, no need to close roads and barriers for a long time, and reduce the impact on road traffic.

　　(5) Diversified choices of design schemes: smart and beautiful shapes, changeable color styles; lighting, green plants, elevators and other value-added supporting facilities are complete, and a high degree of customization can be selected.

　　China currently has the basic conditions for the development of aluminum alloy structural bridges. The development of aluminum alloy structural bridges in line with China's national conditions is of great significance for optimizing the industrial structure of the construction industry, improving the overall level of the industry, and achieving sustainable development.
