In 4 and a half years, China Railway Construction has achieved deep integration of technology and culture, driving Chinese solutions, Chinese technology, Chinese equipment, and Chinese capital to go global in a cluster, adding more stories to the Sino-Russian friendship , Became the fruit of cooperation between the Belt and Road Initiative and the Eurasian Economic Union.

Xiangyun drifts into Moscow

The Moscow Metro has a history of nearly 90 years of construction and is recognized as the most beautiful metro in the world, with strict system and standards. In the 1950s and 1960s, Soviet experts helped to plan and design the first subway line in New China. Today, China and Russia have once again joined hands to build a new Moscow subway.

When I first arrived in Moscow, how to integrate different design concepts, technical standards and management standards between China and Russia became the most difficult point. The builders thoroughly studied Russian design methods and standards, and hundreds of program adjustments and optimizations solved the problems of subway design. Problems such as Russian technical standards integration.

In the design cooperation, we successfully introduced Chinese advanced design concepts, let auspicious clouds float into Moscow, and Chinese elements appeared in the world’s metro art palace. At the Michulin Street subway station, red pillars, group life patterns, auspicious clouds and other rich "Chinese style" auspicious auspiciousness The pattern was unveiled, becoming the first Chinese-style subway station in Europe.

The Chinese Element Metro Station, recognized by the highest design management agency in Russia, stands beside the Friendship Avenue of the Chinese Embassy in Russia, and is praised by the media of the two countries as a new landmark of Sino-Russian friendship. This cross-cultural spectacle along the Belt and Road is officially launched.

The builders actively responded to the differences in the technical standards between the two countries and applied them for the first time in the field of Russian subway construction. A number of innovative technologies such as the receiving process of reinforced concrete boxes have been highly recognized by the government and partners. It fills many gaps in China and Russia in the fields of construction management, construction technology and shield equipment, and creatively forms a set of world-class subway construction technology with Chinese and Russian characteristics.

Shine in Europe

Moscow enters winter from the end of October each year, and the minimum temperature can reach minus 30 degrees. Whether it can break through the extremely cold construction that is rare in the world, Russia has always worried about Chinese engineers. China Railway Construction has independently developed 5 EPB shield machines with a diameter of 6.28 meters, which are named after the five daughters of the Russian hit drama "Dad's Daughters" Maria, Dalia, Galina, and Ballina. Named after Ye Fu Gaining, they have become Internet celebrities in China and Russia.

The five golden flowers are also equipped with a low temperature resistance of minus 30 ℃, the main drive hydraulic pump station, frequency converter and auxiliary heating system make the equipment fully adapt to the extremely cold construction environment in Russia, marking that the underground excavation equipment independently developed by China has reached the construction requirements of the international high-end market. , China Railway Construction has tailored more than 10 Chinese plans to overcome many world-class problems such as the 100-year-old railway under the shield tunnel in operation, and achieved 9 safe originating and receiving, 10 crossing major risk sources, and setting a number of all-Russian Construction records.

China Railway Construction is also fully involved in the construction of various infrastructures in Russia, involving design and consultation of rail transit, highways, general contracting of housing construction, investment and development and many other fields. It has become the largest contractor of Chinese enterprises in Russia, and the relationship between China and Russia has become even higher. Level, a new era of greater development. China Railway Construction's builders will use their hard work and expertise to contribute more beautiful projects to help the development of global sustainable transportation and promote the high-quality co-construction of the Belt and Road Initiative.
