Hangzhou -Chan Railway, the only one!

At 6:13 on July 19th, at the construction site of the Changshan River Bridge of the Hangzhou-Chan Railway, 88#-91#pier turns "turn around" above the Jiujingyu Railway to achieve accurate docking, marking the entire Hangzhou-Shan Railway entire The only consecutive rotation beams successfully completed the rotary construction.

The Hangzhou -Chan Railway is a fast high -speed railway channel connecting Hangzhou and Luzhou City in Zhejiang Province. The total length of the main line is about 131 kilometers. Six stations have a design speed of 350 kilometers per hour. The continuous beam of Changshanjiang Bridge is a key project across the Hangzhou -Chan Railway. The biggest difficulty is that the Jiujingyu Railway, which is operating nearly operating, has high technical requirements and difficult construction. During the construction process, the railway department optimized the rotation plan many times, increased the construction control of the site, overcomes the adverse effects of epidemic, continuous rainfall, and continuous high temperature weather, and successfully completed the continuous beam transition.

According to reports, the continuous beam of the Changshan River Bridge of the Hangzhou -Chan Railway across the Nine Scenery Railway, the oblique angle is 75.5 °, which is the only continuous beam on the entire turn of the Hangzhou Railway. The rotor beam is divided into 11 beams, with a total length of 113.5 meters. The main spans and edges are constructed by the full -hall stent pouring method and the stenting of the stent.

The Hangzhou -Chan Railway is an important part of the intercity rail transit network of the Yangtze River Delta region. Fourth Survey and Design Institute Group Co., Ltd. Hangyu Railway Engineering General Contract. After the project is completed, the multi -point and multi -channel connection of Luzhou to Hangzhou will be realized. Hangzhou City to Luzhou does not have to bypass Zhuji, Yiwu and Jinhua. Residents in the western and counties of Hangzhou to the southwest can transfer to the Shanghai -Kunming high -speed rail through the Hangzhou -Chan Railway to Changsha, Guiyang, Kunming and other places; they can also transfer to Beijing -Guangzhou high -speed rail, to Guangzhou, Shenzhen and other places to further expand and improve Zhejiang Province in Zhejiang Province The railway network skeleton is of great significance to improve the Yangtze River Delta intercity railway network.
