On August 24, 2022, at the construction site of the station building in Wucui District, Yichun City, Yichun City, the Yi section of the Haiyi high-speed railway, with the smooth drilling of the first pile foundation, it marked the official start of construction of the northernmost high-speed railway station in China, Yichun West Station , once again refresh the latitude of China's high-speed rail construction.

Located in the central part of Heilongjiang Province, the Haiyi high-speed railway line is the northernmost high-speed railway under construction in China. The line starts from Tieli City and ends in Yichun City, with a total length of 111.4 kilometers. Tieli, Riyue Gorge and Yichun West Railway Station are three passenger stations, of which Riyue Gorge and Yichun West Station are newly built stations, while Tieli Station is a rebuilt station building.

Yichun West Railway Station

The newly-built Yichun West Station is located at the south side of Yichun Power Plant, Wucui District, Yichun City. The largest station building on the whole line adopts a line-side down-type station, which can accommodate 1,500 passengers at the same time. The station has 2 platforms and 4 lines, and the station building is a structure with 3 floors above ground and 1 floor underground. The railway department has fully considered the functional positioning of the line, combined with the station layout, and adopted a "three-segment" layout of the station building, equipped with advanced and complete service facilities. , the departure hall is set on the left.

Yichun City is located in the hinterland of the Xiaoxing'an Mountains in the northeastern part of Heilongjiang Province. It is one of the largest forest cities in the world. The forest coverage rate exceeds 84.7%, which makes it the "Forest Capital of China". The architectural style of the station integrates regional culture, with the theme of "Lin Hai Xue Yuan, Song Yun Long Teng", the roof of the station building echoes the undulating curves of the surrounding mountains in Yichun, natural atmosphere and stretching, both the beauty and momentum of the mountains.

Yichun West Station is currently under construction in China with the highest latitude and the largest annual temperature difference in the region. . According to Zhang Guoping, the person in charge of the housing construction project of the construction unit China Railway Construction Group Co., Ltd., in order to minimize the impact of the winter break in the alpine region on the construction progress, the construction unit optimized the canopy for the entire station platform from the cast-in-place type to the prefabricated type. The canopy has the characteristics of one-time molding and exquisite appearance. The factory production mode will also greatly improve the construction efficiency.

There are many island-shaped permafrost belts along the line of the Haiyi high-speed railway. The thickness of the permafrost layer at the construction site of Yichun West Station is 2.9 meters. China Railway Construction Group Co., Ltd. and the team of Professor Ling Xianchang of Harbin Institute of Technology carried out the first domestic research on the new technology of antifreeze mineral-based cementitious materials. This is also the first solution in the world that adopts high-performance material technology to solve the frost damage prevention and stability control of water-rich soft soil foundations with high frost heave sensitivity in the construction of high-speed railway station buildings in alpine regions, accumulating valuable experience for the construction of similar projects in China.

Harbin Bureau Group Co., Ltd. gives full play to the supporting and stimulating effect of railway construction investment on economic and social development, resolutely completes the task of railway construction investment and the commissioning of new lines, and closely cooperates with Heilongjiang Railway Development Group Co., Ltd. and Longjiang Railway Co., Ltd., and promotes high standards. Haiyang high-speed railway construction project.

The first project of the Haiyi high-speed rail line will start in April 2021, and it has now entered the construction stage of beams and station buildings. After the completion of the Haiyi high-speed railway line, the running time of passenger trains from Harbin to Yichun will be shortened from the current 7 hours to less than 2 hours, forming a 2 or 3-hour traffic circle with Harbin as the center, which will give full play to the role of railway construction in driving the economy of Longjiang. The fundamental and key role in growth and promotion of coordinated regional development is of great significance. Editor/He Yuting
