New tianjin west railway station to the construction of the beijing-shanghai high speed railway is the five one of railway passenger transport hub, is designed, the beijing-shanghai high-speed railway, tianjin qin the beijing-tianjin inter-city railway and tianjin railway into the hub station of tianjin, the station building facade to lean forward the sunrise full of electromotive force of the arch cloud image performance, implies the development of tianjin city to a better future.
According to Beijing construction group of tianjin west railway station project department chief engineer Chen Shuohui is introduced, and the central station of tianjin west railway station USES the pile foundation, track layer for steel pipe concrete column and frame structure of the strength of reinforced concrete beam, roof part adopts square grid arch roof, auxiliary building with pile foundation, reinforced concrete frame structure, the canopy is composed of concrete-filled steel tube column and steel beam frame structure system, the viaduct with concrete filled steel tube columns, steel box beam structure. In construction, Beijing construction group of tianjin west railway station to the tight project department take the positive measures to solve the complex, the safety pressure, construction technology, engineering quality requirement is high, need coordination of the department of many difficulties, make tianjin west station station project main structure smooth caps on November 18.
According to Chen Shuohui, tianjin west railway station to station building roof of square grid type truss structure is novel and chic, its height and span of built and planned in China's railway station in the forefront, steel structure construction is very difficult, so in the installation construction scheme selection of organized many experts. At high altitude, accumulating sliding, overall improve construction scheme, such as cooperated-builing parties had a heated argument, eventually Beijing construction group and insist on using both sides adopt overall increase in the middle of scattered, recognised by the ministry of construction schemes, after implementation to achieve project goals. Used in the process of construction of the prestressed cable are ascending segment deformation control; For the whole process of stress and strain monitoring of steel structure upgrade; Using laser scanning technology auxiliary installation, close its mouth to multiple docking ports at the same time play an important role.
