Guangxi transportation construction has added a new chapter! The world's largest span stiff skeleton concrete arch bridge, the Tian'e Longtan Bridge on the old highway from Nandan to Tian'e Xia, Guangxi, was officially opened to traffic, marking a new milestone in Guangxi's transportation construction. This spectacular bridge not only made a major breakthrough in technology, but also played a pivotal role in the strategic layout of transportation.
Tian'e Longtan Bridge, located 6 kilometers upstream of Longtan Dam in Tian'e County, Hechi City, across the Hongshui River, is the control project of the old highway from Nandan to Tian'exia. The total length of the bridge is 2488The 55-meter, main bridge is a 600-meter-diameter upward-bearing stiff skeleton concrete arch bridge, which has broken a number of world records in the field of bridge construction and is known as the "top of the world's arch bridges".
The construction of this bridge is nothing short of miraculous. The top team led by Zheng Jielian, an academician of the Chinese Academy of Engineering, and the technical support of Guangxi University enabled the Tian'e Longtan Bridge to overcome one technical problem after another during the construction process. From the full construction on July 25, 2020, to the smooth closing of the outer concrete floor ring on June 6, 2022, and then to the completion of the outer concrete construction on April 30, 2023, each stage has condensed the wisdom and sweat of countless builders.
The completion and opening of the Tian'e Longtan Bridge will reduce the travel time from Nandan to Tian'e from the original 1The shortening of 5 hours to 40 minutes has greatly improved traffic efficiency and injected new vitality into the economic and social development of the two places. The construction of this bridge not only demonstrates China's leading technology in the field of bridge construction, but also is one of the key scientific and technological projects in the national transportation industry.
As the world's first arch bridge with a span of more than 600 meters, the construction of Tian'e Longtan Bridge has provided valuable experience for the world's bridge construction. Its successful completion not only reflects China's strong strength in infrastructure construction, but also demonstrates the wisdom and innovative spirit of Chinese engineers to the world.
The successful opening of the Tian'e Longtan Bridge not only strengthens the connection between Nandan and Tian'e, but also makes us proud of the motherland's achievements in the field of bridge construction! The completion and opening of this bridge to traffic will undoubtedly write a strong stroke for the transportation development of Guangxi and even the whole country.
Let us look forward to the world's largest span stiff skeleton concrete arch bridge to play a greater role in the future and provide strong support for regional economic and social development. At the same time, it is also expected that Guangxi will make more brilliant achievements in the field of transportation construction, and provide more reference and experience for the development of transportation in the country and even the world.
