On August 17, at the construction site of the Tongjiang Sino-Russian Heilongjiang Railway Bridge, the installation of the last set of track cleats for the Sino-Russian standard-track interface was completed, marking the first cross-river railway bridge between China and Russia-the Tongjiang Sino-Russian Heilongjiang Railway The track laying of the bridge has been completed, laying a solid foundation for the opening and operation of the entire bridge.
The Tongjiang Sino-Russian Heilongjiang Railway Bridge is located between Tongjiang City, Heilongjiang Province, China and Ningskoye City, Russia. The bridge is 7,194 meters long, the approach bridge is 4979 meters long, and the main bridge is 2215 meters long, of which the main bridge in China is 1886 meters long. , The main bridge in Russia is 329 meters long, with a designed operating speed of 100 kilometers per hour and an annual cargo delivery capacity of 21 million tons.
According to the China Railway Harbin Bureau Group Co., Ltd., the construction of the Tongjiang Sino-Russian Heilongjiang Railway Bridge has created many records. It is the first cross-river railway bridge connecting China and Russia. It is the first domestically and internationally to use steel truss girder to lay a four-track track ballastless track slab construction program. During the bridge design stage, the Chinese and Russian engineers and technicians conducted in-depth and detailed studies on the bridge and track design standards of the two countries, and finally jointly determined the design plan for the use of sleeve rails, which can adapt to the different standard gauges of China and Russia (Chinese gauge 1435 Mm, the Russian gauge is 1520 mm). During the construction period, the participating units overcome hard ice, frozen soil, sand gushing and other problems, and innovated anti-corrosion coating, high-bolt construction, and deep-water cofferdam anti-collision technology in high-cold areas, ensuring the smooth progress of the bridge construction.
The Tongjiang Sino-Russian Heilongjiang Railway Bridge connects to the three northeastern provinces in the south and radiates the whole country. It connects to the following Ningskoye Port of Russia and the Russian Far East Railway through the Tongjiang Port to the north, and to the hinterland of Russia through the Trans-Siberian Railway to the west. The railway transportation channel between my country and Russia will also open up a new Eurasian combined transport channel from West to Europe. After the completion and opening to traffic, the railway transportation distance from Heilongjiang via Tongjiang to Moscow will be shortened by 809 kilometers compared with Suifenhe port, saving 10 hours of transportation time, and will greatly alleviate the transportation pressure of Manzhouli and Suifenhe railway ports.
