The longest distance and the highest design speed, the new "Wanli Yangtze River First Tunnel" starts construction

The Yangtze River Daily Da Wuhan Client September 7th (Correspondent Zhang Qishan reporter Wang Wenhan) At 9:00 on September 7, the largest underwater shield tunnel in China, which was designed by the Fourth Court of Tie Fourth Hospital, officially started the Haitai Yangtze River Tunnel.

The Haipai Yangtze River Tunnel is a key public railway crossing the river in my country by 2025. It starts from the Shanghai -Shaanxi Expressway in Haimen District. The outer diameter of rice, the horizontal cross section of the shield is 16 meters, the design speed is 100 kilometers per hour.

As the longest -distance, the largest section and the highest design speed of the underwater shield tunnel, the Haipai Yangtze River Tunnel has always attracted much attention.

Faced with many technical problems of the "First Tunnel of the Yangtze River", the design team of the III Court from the feasibility research plan to the preliminary design results, and then to the construction map design blueprint, step by step to realize the project landing construction. During the design stage alone, five major groups such as the "oversized diameter shield tunnel structure, waterproof and fire prevention integrated research" were set up, and nearly 60 universities and scientific research units were recruited to participate in the research support design plan. Its design process has carried out a total of more than 60 special research, and systematically studied the tunnel structure and waterproof and fire prevention and fire prevention, disaster prevention and mitigation, green low -carbon, construction and equipment and intelligent construction management.

According to reports, after the completion of the tunnel, the implementation of the national strategy for the development of the Nantong Suzhou integrated development and the development of the Yangtze River Economic Belt in the Yangtze River Delta region, optimizing the layout of the Yangtze River Crossing Channel, improving the regional high -speed railway and highway networks, promoting the construction of the Yangtze River urban agglomeration and the integration of cross -river integration Development is of great significance.

In the future, Haimen can cross the Yangtze River in 10 minutes, and can reach the center of Shanghai in half an hour. Haimen will become the "forefront" driven by Shanghai and southern southern southern radiation north of the Yangtze River.
