Cold brings pressure slurry congratulated China on its longest high-speed lines joining master Bridges

Cold northern xinjiang of China is the longest high-speed line master bridge is a closure, better high-speed railway from Harbin in heilongjiang province to jiamusi electrified double-track railways in China. Circuit design total length of 343 km, this more than the previously opened ha's high-speed rail and are building ha negundo high-speed rail. Therefore, ha better railway is currently the longest China northern xinjiang alpine region of high speed railway. According to responsible for the construction of the railway bureau relevant controller introduces, Shanghai, Harbin super-large bridge engineering better railway was well versed in the control of project, the total length of 13. 2 km, total pier 401, continuous beam 5, about a third of the piers in the water, construction difficulty is great; Among them, the total length of 177. 5 meters across the ring of high-speed continuous beam is the biggest span continuous beam of Harbin super major bridge, due to considering the bridge in cold area will be under the influence, the project department asked some of China's outstanding technical experts repeatedly to optimize the preloading construction technology and construction organization, hanging basket, after many test demonstration, finally to ensure smooth closure mainspan implementation. The relevant person in charge of Harbin railway bureau said that the bridge after completion of the final closure ha railway will go into the next frame beam, track-laying projects, completed in 2018 is expected to achieve; Ha better railway, will and the team specialized, haaqi's high-speed, high ha negundo iron to form a high-speed passenger transport network in northeast China, this will greatly improve the 'three vertical and four horizontal' railway network in northeast China for system capability, and to promote the two sides in various fields between China and Russia, to accelerate the development of northeast Asia regional cooperation has important significance.
