Hunan University built the first bamboo bridge accessible to cars with a span of 10 meters
On October 28, at the opening ceremony of the first International Symposium on Modern Bamboo Structures held at Hunan University, Professor Xiao Yan, Dean of the School of Civil Engineering at Hunan University and Yangtze River Scholar, excitedly announced to experts from more than 10 countries that the school had recently A bamboo structure bridge with a span of 10 meters has been built in Yangshi. It will be the first bamboo structure bridge in the world to carry vehicles.
Hunan’s bamboo planting area and bamboo production are among the top in the country, and bamboo products also have a certain influence across the country. The research team led by Xiao Yan conducted a systematic study on modern bamboo structural technology. Last year, they successfully built the first bamboo footbridge. After nearly a year of continued research and development, the research team recently built a 10-meter-span bamboo structure bridge in Leiyang City. This is a rural road bridge with a clear width of 3.5 meters and nine 10-meter-long bamboo beams. , the designed traffic load is 8 tons, but the actual carrying capacity is about 90 tons. At present, the bridge has passed many tests and is expected to be opened to traffic in November. It is estimated that it can be used for 20 years.
The research team built a test bridge on the campus of Hunan University that is exactly the same as the bamboo structure bridge system in Leiyang City. From the appearance, the bamboo structure bridge is not much different from other bridges. Except for the bridge deck, which is made of prefabricated concrete panels, the other load-bearing components are all bamboo components. According to Xiao Yan, they compounded high-performance carbon fiber reinforced plastic with a bamboo structure, greatly increasing the span of the bridge and overcoming the manufacturing problem of integrally formed bamboo beams. Moreover, the cost of bamboo-structured bridges is half that of steel-structured bridges, which is similar to that of steel-structured bridges. Compared with concrete structure bridges, the construction period is shorter, there is less pollution, and it is easy to maintain.
Domestic and foreign experts and scholars have shown strong interest in the bamboo structure mobile houses and bamboo structure test bridges of Professor Xiao Yan’s research group, believing that these works are important for the development of modern bamboo structure technology and the promotion of the practical use of modern bamboo structure technology. Chemicalization plays an important role, and at the same time it effectively improves the utilization rate of bamboo and the added value of products, improves the level of Hunan’s bamboo industry, and adds new economic growth points.
