Qu Lihua followed Xia Yuxiang, the head of the group, visited the railway construction site for two days, the project was grand, and in the next three days, Su Xiaoyu took everyone to the Tongjiang Sino-Russian Railway Bridge for a field trip.

The members of the delegation have heard about this project in China, and they are very excited to witness the style of the Sino-Russian Railway Bridge in Tongjiang.

Su Xiaoyu said: "China and Russia are friendly neighbors, since the Belt and Road Initiative was proposed in 2013, many strategic projects between China and Russia have been vigorously carried out, especially in the pragmatic cooperation for the purpose of achieving connectivity, the construction projects of railways, highways and bridges within the framework of the Belt and Road Initiative are achieving new breakthroughs. The construction of the Tongjiang Railway Bridge, the Black Sea Highway Bridge, and the Trans-Heilongjiang Cableway has been launched, and projects such as the Moscow-Kazan high-speed railway, the Northern Passage, and the Belkaml Railway are under active planning and construction. ”

"Due to the time relationship, we will select two representative projects of Sino-Russian cooperation to investigate, one is the Moscow-Kazan high-speed railway that we have been to before, and the other is the Sino-Russian railway bridge in Tongjiang that we are now inspecting. If we want to develop the economy, we must first build railways, bridges, roads, and airports. ”

Xia Yuxiang smiled, "In recent years, China's achievements in infrastructure have attracted the attention of the world, the country's face is changing with each passing day, Beijing-Shanghai high-speed railway, Harbin-Dalian high-speed railway, Qingdao Bay Bridge, Hong Kong-Zhuhai-Macao Bridge, Beijing Daxing International Airport and other super projects shocked the world, 'Fuxing' EMU, C919 large passenger aircraft, Zhenhua port machinery and a number of domestic transportation equipment marked a new height of Chinese manufacturing. ”

"Chinese have always forged ahead for the great rejuvenation of the Chinese nation and the prosperity of the motherland, and China has brought more development opportunities to Asia, Africa, Europe and other regions by strengthening connectivity, and we hope that countries along the route can develop together." ”

In order to let the members of the delegation know more about the Tongjiang Sino-Russian Railway Bridge, Su Xiaoyu also specially invited an engineer from Shandong, China, Sun Haoyu to introduce to everyone.

Sun Haoyu, 37 years old, 1.80cm tall, wearing an orange hard hat and blue overalls, briefly introduced himself and greeted the members of the delegation.

"Today's weather is very good, the sky is clear, welcome everyone to visit the Tongjiang Sino-Russian Railway Bridge, this project many of our Chinese engineers and construction personnel have paid a lot of time and energy. ”

He looked back and pointed back, Qu Lihua followed Sun Haoyu's finger and looked over, the blue sky and white clouds, the bridge has been extending forward, it stands proudly on the river like a behemoth, it looks particularly grandiose, the bridge pier is very solid, standing steadily, submerged in the river, the bridge body is winding and long, like a huge dragon lying on the river.

Sun Haoyu explained: "The Tongjiang Sino-Russian Railway Bridge Project was laid on February 26, 2014, and is the first cross-border river railway bridge between China and Russia, with a designed annual railway capacity of 21 million tons. The total length of the bridge is 7193.71 meters, of which the total length of the main bridge is 2215.02 meters, 1886.45 meters in China and 328.57 meters in Russia. ”

"Tongjiang Sino-Russian Railway Bridge is the first cross-border railway bridge in Heilongjiang Province that connects with Russia, and the project is located on Hayu Island, Tongjiang City, Jiamusi City, across the river from Nizhny Leninskoye, Jewish Autonomous Prefecture of Russia. The Tongjiang Bridge Project has a total length of 31.62 kilometers in China, including a Heilongjiang Bridge, a Sancun Bridge, lead lines and station related projects. Among them, the Heilongjiang Bridge has a total length of 7,500 meters, penetrating the border between China and Russia, and the main bridge has a total of 20 spans and a total length of 2,215.02 meters. The main span of 144 meters of steel beams crosses the Sino-Russian border, and the Chinese side is responsible for the construction of the steel beams. ”

"As the first railway boundary river bridge between China and Russia, the Tongjiang Sino-Russian Cross-River Railway Bridge is an important cooperation project of the Belt and Road Initiative and the Eurasian Economic Union. The construction of the Tongjiang Sino-Russian Railway Bridge can connect the Tongjiang Port with the Nizhny Leninskoye Port in Russia, connect with the Trans-Siberian Railway, connect Khabarovsk, the largest city in the Far East, and connect the European continent in the west. ”

"After the completion of the bridge, the annual cargo capacity in the near future will be 21 million tons, and it will become an important emerging port channel to promote the docking and cooperation between the revitalization plan of Northeast China and the development plan of the Russian Far East, which is of great significance and far-reaching impact. ”

"It is not easy to build this bridge, our engineers and workers have spent a lot of effort on this bridge, they have paid hard work, we all have feelings when we look at it, and we can proudly say that I also participated in the construction of this project in the future, and I have made a little contribution as much as I can." ”

"Our engineers and employees are very dedicated and meticulous in their work, and we also know that we have to shoulder the heavy responsibilities, carefully read the drawings, and strictly follow the specified requirements for construction. ”

"Engineer Sun, is there Heilongjiang at the foot of the bridge?" Qu Lihua asked.

Sun Haoyu smiled and nodded, "Yes, the foot of the bridge is the rolling Heilongjiang, I took you to board the approach bridge of the construction of the Sino-Russian Railway Bridge in Tongjiang, and now the construction has entered the final stage, and the bridge construction workers are sweating like rain to dismantle the approach bridge." ”

Qu Lihua looked up and saw that there were large cranes in the distance, as well as scaffolding and cranes, all tall and heavy, all "big guys", the workers were busy, they were all wearing uniform work clothes, and they looked very neat.

Sun Haoyu said: "Our Chinese construction workers will be issued blue overalls with an orange hard hat, and when entering the construction site, they must wear hard hats and do a good job of safety measures. ”

Meng Wenjie asked: "Engineer Sun, when we designed and constructed, did we take into account whether the bridge can withstand low temperatures when the temperature is relatively cold?"

Like Qu Lihua, Meng Wenjie is also a member of the delegation, Meng Wenjie and Qu Lihua are of the same age, only one year older than her, also single, in an international trading company as a department head, very tall, fair skin, low-key and steady, a few days ago, he followed Xia Yuxiang's side and rarely asked questions, today he was very interested in this question, so he asked Engineer Sun Haoyu for advice.

"Yes, whether it is Heilongjiang or Russia, the temperature in winter is very low, located in the alpine region, the low temperature has been below zero degrees The design of this Sino-Russian cross-river railway bridge also fully takes into account the climatic factors, the steel plates we choose are low-temperature resistant materials, and also fully takes into account the principle of thermal expansion and cold contraction, leaving an appropriate distance between the seams of the track and the track. ”

"In addition to low temperature resistance, in order to take into account the different railway track widths of the two countries, the bridge uses a set of rails, both Russian 1520 mm wide rails and Chinese 1435 mm wide rails, to ensure that Chinese and Russian trains can run normally on the bridge. Moreover, when the bridge was designed, environmental protection factors were fully considered, and for the first time, ballastless tracks without ballast were installed on the steel girder structure railway bridge. ”

Although Qu Lihua is not a professional bridge design and construction personnel, and there are some professional terms that she can't understand, she still listens very carefully, takes out her notebook, and takes notes seriously.

"This is really a very remarkable large-scale engineering project, we have professional bridge construction professionals on the Chinese side, the experience is still very rich, the Chinese side is responsible for the construction department, we will build the construction, the part that needs to communicate and cooperate with the Russian side, our person in charge, the engineer will negotiate and cooperate with them, everything is going smoothly, the project has entered the final stage. ”

Head Xia Yuxiang praised: "We Chinese are indeed very diligent, very hardworking, and have created many miracles, this bridge is magnificent, and we are very proud and proud of the bridge designers, engineers, and construction personnel, which is really amazing."

Sun Haoyu smiled, "the credit is everyone's, I am just one of the members involved in this project, the Sino-Russian cross-border railway bridge design annual cargo capacity of 21 million tons, the design maximum speed of 100km, after the completion of the bridge, will end the Sino-Russian border river Heilongjiang no cross-river railway bridge history, can be China's northeast railway network directly connected with the Russian Siberian Railway, set up a connection to the three eastern provinces, radiation of the whole of China, through the north and south of the international intermodal freight railway channel, railway transport greatly reduced the cost of cross-strait merchants. ”

Qu Lihua listened to the explanation of engineer Sun Haoyu, overlooking the Heilongjiang River at the foot of the road, under the blue sky and white clouds, the river is rushing forward, magnificent, the sunset in the distance reflects the sky, sprinkled a halo, the clouds slowly floated over, and after the completion and opening of the project, it will definitely create a beautiful prospect and unlimited business opportunities, and promote trade between the two countries.
