The first alien octagonal asymmetric basket in the country is completed and opened to traffic

On June 29th, the first alien octa -facial elevation basket arch bridge, the first alien octagonal bridge of the China Railway Second Bureau, was opened to traffic.

The Shunjiang Bridge is located in Shangyu District, Shaoxing City, Zhejiang Province. It builds a traffic -oriented people who benefit millions of local people, improve the transportation network of Shangyu District, enhance cross -river traffic capacity, improve the current traffic congestion of crossing the core area, and promote the "embrace Jiangxi advance in Jiangxi. "Development is of great significance.

New progress has been made in the world's largest span Three Tower Cold Bridge

On June 28th, after 22 hours of continuous fighting, the world's largest span three tower trapped bridge -Chaoma City Railway Maanshan Gong Railway Bridge Main Tower No. 3 Pier beams 3 Piece of Cyders from the China Railway Bridge Bureau The pouring is completed.

Ma'anshan Gong Railway Bridge The Yangtze River Bridge is a key control project of the newly built Chaoma Intercity Railway. It is the largest span of the world's largest three towers and two main spans. The main bridge of the bridge is 3253 meters. The upper highway of the bridge is a two -way six -lane city expressway with a design speed of 80 kilometers per hour. The lower two lines are the Chaoma Intercity Railway with a design speed of 250 kilometers per hour. The scale of the bridge construction project is large, the technological content is high, and the construction environment is complicated, which will create a number of world records.

The world's widest entire -sea cross -sea steel box beam holding bridge -the Zhongshan Bridge in the Shenzhen Channel smoothly meets the dragon

On June 28, with the last steel box beam with a length of 10 meters and 46 meters wide and 46 meters wide, the crane beam weighing 233 tons was completed. Hai Steel Box Beam Covenant Bridge -the Zhongshan Bridge in the Shenzhen -Middle Channel is smooth.

The Shenzhen -Middle Channel is another world -class cross -sea cluster project that integrates the "bridge, islands, tunnels, and underwater interoperability" after the Hong Kong -Zhuhai -Macao Bridge, with a total length of 24 kilometers. Among them, the bridge project is about 17.2 kilometers long. As one of the key control projects of this project, Zhongshan Bridge is 580 meters. There are two main towers in the east and west. Mi, weighing 428 tons, a single standard segment steel box beam area is equivalent to 2 international basketball court area, and its weight is equivalent to 300 cars weigh.
