Who built the Wuhan Yangtze River Bridge?
From the history of Wuhan Yangtze River Bridge, we can see who designed and built Wuhan Yangtze River Bridge. Please see: 19 13—— george miller, a German professor from Peking University, led 13 civil engineering graduates to plan and measure the "Wuhan Memorial Bridge" with the support of Zhan Tianyou, the director of Sichuan-Han Railway at that time, and put forward three schemes for the bridge site line and bridge between Guishan and Sheshan, all of which are both roads and railways. This is the first idea of building a modern bridge in Wuhan. 19 19- Sun Yat-sen also put forward the idea of building the Yangtze River Bridge in Wuhan in the General Plan for the Founding of the People's Republic of China. In the following decades, groups of Chinese and foreign bridge experts, such as Walter (USA), Mao Yisheng, Luo Ying, Li Wenji, Tian Yichun and others, as well as everyone in China, devoted infinite passion to the first Yangtze River Bridge. However, this dream never came true in old China. 1934 —— Mao Yisheng presided over the Qiantang River Bridge Engineering Office to survey and drill the bridge site of the Yangtze River Bridge, and asked China Morina Sanderson Engineering Consulting Group to draw up another bridge construction scheme: the bridge site is from the Yellow Crane Tower in Wuchang to the Lianhua Liujiaqiao Wharf in Hanyang, with a length of 1932 m, two piers with 8 holes and a main span of 237.74 m between piers 6 and 7, and the first floor of the bridge deck is erected with arched steel beams. The net height of the highest flood level under the bridge is 30 meters, and the largest river boat can be navigable; Railway bridges and highway bridges are respectively erected on the Hanjiang River, and the construction period is 4 years. These two plans inspired future generations to build bridges. 1949- The Central People's Government has decided to build Wuhan Yangtze River Bridge. 1950- the State Council instructed the Ministry of Railways to carry out survey and design. (1950, Wang served as the head of the steel beam design team of Wuhan Yangtze River Bridge. At the beginning of the founding of the People's Republic of China, he lacked experience in building this complex and huge project, and invited Soviet experts to provide technical assistance. However, the American bridge standards that Wang once owned are quite different from those of the Soviet Union. After accepting the task of discussing Soviet bridge specifications, he diligently taught himself Russian, and soon he was able to read Russian professional books, compare the technical standards of the United States and the Soviet Union, and understand and implement the suggestions of Soviet experts more easily on the basis of theoretical principles. )1953 —— Complete the preliminary design in March, hire Soviet experts to guide and entrust the Soviet Ministry of Communications to appraise the design scheme. (1953, Wang, the technical chief of Wuhan Yangtze River Bridge Engineering Bureau, together with Liu Zengda, a Chinese bridge expert and then deputy chief, led the general practitioner to carry out the overall design and construction design of Wuhan Yangtze River Bridge while drawing the steel beam scheme himself. In the design of the steel beam of Wuhan Yangtze River Bridge, in order to give full play to the material strength, simplify the manufacturing work and facilitate the riveting operation on the river surface at high altitude, the main truss member adopts H-shaped section, and the exchange of members is considered to adapt to the adoption of non-hole assembly technology by the bridge manufacturer, which has played a very good role in ensuring the manufacturing and installation accuracy of the steel beam. Cantilever assembly method is an important progress of beam erection technology in China. These were designed by most young engineers and technicians under the specific guidance of Wang, and their layout and detailed structure are still used by many long steel beams built in China in the future. ) 1955 —— The technical design was compiled by the Bridge Engineering Bureau of the Ministry of Railways at the beginning of the year, and the bridge construction project started in September 1. 1957-end of September, completed. 65438+1October 65438+May officially opened to traffic. At present, there are 9 bridges 109 in Wuhan, including 9 bridges across the Yangtze River and Hanjiang River, 32 overpasses 10, 32 footbridges, 58 bridges across the river and other bridges, with a total area of 420,000 square meters.
