Construction of the Yongzhou Railway began later this month to complete the final piece of the “puzzle” of Zhejiang’s “Shitong high-speed railway” -Hangzhou News Center-Hangzhou Net

Zhejiang DailyThe reporter learned from the press conference on the start of construction of the Yongzhou railway held on the morning of December 15 that the construction of the world-class railway project of the Yongzhou railway will begin in the second half of this month, the The last city in the Zhejiang district that does not have rail access. Zhoushan is getting closer to realizing the dream of “high-speed rail on the island”. After the completion of the Yongzhou Railway, the last piece of the “puzzle” of Zhejiang’s “city-to-city high-speed rail” will be added.

“Great. From now on, Ningbo and Zhoushan are like the same city. I can go home every day!” Li Yuemin, a Ningbo native who works in Zhoushan, was very excited when he heard the news. The journey of less than half an hour will allow him and his family to end their lives at a distance. According to the calculation of the direct mode of the grand station, the travel time from Zhoushan to Ningbo will be reduced from 1.5 hours to 26 minutes, and the travel time from Zhoushan to Hangzhou will be reduced from 3.5 hours to 77 minutes, making it the most convenient passenger passage between the mainland and Zhoushan Island.

In October this year, the Provincial Development and Reform Commission approved the preliminary design of the Yongzhou Railway. At present, all the preliminary work is basically finished and the conditions for construction are ready. The line starts from Ningbo East Station in the west, passes through Yinzhou District, Beilun District, Zhoushan City, Jintang Island, Cezi Island, Fuchi Island and Zhoushan Island. . 4 stations in Tang, Ma’ao and Zhoushan will be renovated, 3 existing stations in Ningbo East, Yunlong and Qiuai. The total length is 76.4 kilometers, of which the new line is 70.1 kilometers. The Ningbo railway hub is connected to the Ningbo-Taiwan-Wenzhou railway to the south, the Yong-Jin railway to the southwest, the Hangzhou-Ningbo dedicated passenger railway to the west and northwest, and connects the Hangzhou-Changzhou, Nanjing-Hangzhou lines, Shanghai-Hangzhou, Shanghe-Hangzhou through downtown Hangzhou. The total investment of the project is about 27 billion yuan, the PPP model is adopted, and the construction period is 6 years.

According to the design, the Yongzhou Railway passing through the Jintang waterway will adopt a road and rail tunnel scheme; Crossing the Xihoumen, Taoyaomen and Fuchimen waterways, a rail bridge scheme will be adopted. By then, “One Tunnel” and “One Bridge” will become the best in the world.

The 16.18 kilometer Jintang Submarine Tunnel is 10 kilometers longer than the Hong Kong-Zhuhai-Macao Bridge Tunnel and is the longest underwater high-speed rail tunnel in the world. “The sea-crossing tunnel of the Hong Kong-Zhuhai-Macao Bridge is 6.7 kilometers long and belongs to a submerged tube road tunnel, while the Jintang Tunnel is a high-speed rail protection tunnel, a one fifth of the length of the entire line goes into the seabed. ” Project manager of China Railway Fourth Survey and Design Institute Group Co., Ltd. Chen Xiaoquan said. The Xihoumen Road and Railway Bridge with a main span of 1488 meters is a joint road and railway bridge spanning the Xihoumen Canal on the Yongzhou Railway and Yongzhou Expressway. Upon completion, it will be the world’s largest road-rail joint construction bridge, increasing the extension capacity of China’s railway bridges from the one-kilometer level to the 1,500-meter level.

The start of construction of the Yongzhou Railway means that another major project, the Yongzhou Expressway Double Line, has also entered a substantial implementation stage. Yongzhou Expressway Double Track is built in accordance with the six-lane two-track standard. The line is 45.23 kilometers long, starting from Haosifang, Beilun, Ningbo, passing through Jintang Island, Cezi Island and Fuchi Island to Zhoushan Island and finally to Dasha Island on Zhoushan Island. The Yongzhou Expressway double line will be implemented in sections. Among them, the stretch from Jintang to Dasha will be built concurrently with the Yongzhou Railway in 2022 to save canal resources and investments.

With the acceleration of a number of major transportation projects with the Yongzhou Railway as the leader, including the Yongzhou Expressway Double Track, a group of the world’s first sea-crossing bridges with the Yongzhou Railway as its culmination point iconic will gradually show its glory.
