Nanjing Yangtze River Tunnel Run on behalf of the highest standards in today's China – Nanjing Yangtze River Tunnel, through, tunnel construction – construction machinery industry
Nanjing Yangtze River Tunnel Run Nanjing Yangtze River Tunnel Development and Reform Commission and the company announced on the 19th: on behalf of China today, the highest standards of construction of underwater tunnels, the state, "the 863" demonstration projects subject of the Nanjing Yangtze River Tunnel, the left tunnel will be May 20th through the morning alluvion out of the hole successfully. The right line through the tunnel in October this year, the Nanjing Yangtze River Tunnel opened to traffic until around June next year. After the opening of the tunnel fees may be reference to the Yangtze River Bridge.
"Left tunnel Shield Is under water 'the hole', we must subject the well to rain before they can see it's true capacity. "China Railway 14 Bureau Group of Nanjing Yangtze River Tunnel, said the company's total work Guoxin Jun, in the shield project, the shield," the hole "caused the accident probability of a larger, so they took a year to perfect the shield machine" out of hole "program, underwater" the hole "is just one of safety.
Nanjing Yangtze River Tunnel is known as "the first underwater construction difficult"
Nanjing Yangtze River Bridge and the Third Bridge Crossing is located between the Yangtze River, South Riverside Avenue from the Hexi Corridor, north to Pukou new urban area, length 3032 m, designed for two-way six-lane, lane 80 km expressway, opened to traffic, Pukou from the main city to a new city only about 10 minutes, Jiajiang Bridge makes a step movement in the main city alluvion. Tunnel opened to traffic, the city will have two channels to cross the river (another channel for the Second Bridge Yangtze River Bridge, three bridges for the cross-border bridge), the river will greatly ease the difficulty, shortened Jiangbei and temporal distance from the main city, promote the development and Jiangbei River City owns the development.
Present, the Yangtze River has been completed and the bridge under construction has more than 60 of the finished tunnel across the river is only middle of the city of Wuhan, Nanjing and only in the construction of Chongming Island, Yangtze River estuary.
Construction side, President of China Railway Construction shares Zhao Guangfa introduction, the Nanjing Yangtze River Tunnel in a depth of 65 meters of water across the Yangtze River, the tunnel bear per square centimeter of water pressure up to 6.5 kilograms, is by far the most difficult Yangtze River Basin Engineering , the most complicated geological conditions, problems and challenges of the most world-class cross-river tunnel project, known as "the first underwater construction difficult." They put into research funding has more than 3,000 yuan, an expert team composed of more than 60 people for more than 60 research projects conducted a special study. At present, the tunnel construction has resolved more than 40 construction risk, successfully resolving a high-pressure, high-permeable layer of tunnel under the 100-year design life of the world-wide problem.
