The design speed of the tunnel section is 80km/h, and the clear width is 2×12.25m. The navigation clearance height of the bridge in the main channel of the left branch of the bridge is not less than 32m above the designed maximum navigation level, and the effective width of the 10.5m deep-water channel covered by the main navigation hole on the left side is not less than 150m.

Basic introduction Chinese name: Nanjing Yangtze River Fifth Bridge mbth: Fifth? Full length of Nanjing Yangtze River Bridge: 1 1.99km Geographical location: 5km downstream of the Third Bridge and13 km upstream of the Bridge; Design speed: 80km/h Bridge type: construction history, bridge type scheme, route scheme, Jiangnan approach bridge, construction significance, honors won and the construction history of Nanjing Yangtze River at the end of 2008. From March 2, 2009 to April 2, 2009, the staff of Jiangsu Hydrogeological Engineering Geological Survey Institute will conduct geological exploration in six boreholes in the middle of the Yangtze River in the upper reaches of Huamian Tiqi Ferry in Dashengguan Waterway in Nanjing section 1000 meters, and the results will be combined with other relevant data to form an engineering pre-report. On June 17, 2009, the review meeting of geophysical and geological investigation report of Meizizhou river crossing channel (namely Nanjing Yangtze River Fifth Bridge) was held, and experts agreed that the site selection of the Fifth Bridge was suitable. 20 13 Nanjing Yangtze river fifth bridge carried out preliminary study and completed feasibility study with an investment of 6 billion yuan. 20 14,10122 October, the "bridge+tunnel" mode was formally finalized for the Fifth Bridge, and the recommended scheme was changed to "bridge+tunnel" mode, and it was decided not to build a double-deck bridge. The construction of Meizizhou River Crossing Channel is divided into two stages according to the Work Permit, and the tunnel part has been opened. 20 15,110/0, the feasibility study report of the fifth Nanjing Yangtze River Bridge project has been submitted to the Ministry of Transport, and it is expected to start next year and be completed in the 13th Five-Year Plan. 20 16 On July 28th, the National Development and Reform Commission approved the construction of the fifth Nanjing Yangtze River Bridge. On the afternoon of April 27th, 20 17, the first steel pipe pile of the middle pier cap was successfully driven into place by a piling boat at the construction site of A 1 section of the Fifth Nanjing Yangtze River Bridge, which marked the official start of the middle pier construction of the Fifth Nanjing Bridge. 2065438+On the morning of May 23rd, 2007, the 14th Bureau of China Railway started the first drilling of the enclosure structure at the Jiajiang Tunnel construction site of the fifth Nanjing Yangtze River Bridge project, which opened the prelude to the construction of the bid section. 20 17 At 3: 30am on July 6th, 2007, the concrete pouring of the first pile foundation Z5- 17# of the south main pier of Nanjing Fifth Yangtze River Bridge was successfully completed. 7: 10, the first pile foundation of S9-3 of the south approach bridge was drilled successfully. The successful pouring of the first pile foundation of the main pier and the drilling of the first pile foundation of the south approach bridge are the successful construction of the first pile of the main bridge and the approach bridge of Nanjing No.5 Yangtze River Bridge, which indicates that the main project of Nanjing No.5 Yangtze River Bridge has entered the stage of full implementation. On September 30th, 20 17, the last bored pile of the north main pier of the No.5 Nanjing Yangtze River Bridge was successfully poured. The bored pile construction of the north main pier lasted for 3 months, which was completed 1 month earlier than the original plan. As a result, the main construction of the north main pier smoothly entered the pile cap construction process from the drilling pile process. 201165438 at 7: 00 pm on October 2, 2007/kloc-0, the concrete pouring of the south main pier Z5# pier 15# of Nanjing Fifth Bridge Project was successful, and the pile foundation construction of the south main pier of Nanjing Fifth Yangtze River Bridge Project was completed. 20 1 1 171At 8: 00 on October 25th, the steel boxed cofferdam of the middle main pier of the fifth Nanjing Yangtze River Bridge, which was built by the Second Navigation Bureau, completed the bridge site installation process, and the whole process was from the positioning of the transport ship to the floating hook, trial hoisting, displacement, position adjustment and launching. 20 18122 October,18, the main machine of the new era shield machine used in Jiajiang Tunnel of Nanjing Fifth Bridge was assembled. 20 18 18 On February 26th, the cutter head of the "New Era" shield machine was started. Bridge Type Scheme The scheme of the Fifth Nanjing Yangtze River Bridge is "Bridge+Tunnel". That is, the bridge method is adopted in the project of crossing the main stream of the Yangtze River, and the tunnel method is adopted in the project of crossing Jiajiang River. Route Scheme The starting point of Nanjing Fifth Yangtze River Bridge is located at Wuliqiao Interchange in expressway, Ninghe River, which intersects with Lixin Road, Sesame River, Fengzihe Road, China Southern Airlines, Xinmin Road and Binjiang Avenue in turn from north to south, then crosses the main channel of the Yangtze River and lands on Meizizhou Island, forming an interchange with the planned Puyuan Road. Then the route passes through Jiajiang, reaches the south bank of the Yangtze River, passes through Binjiang Avenue on the third floor of Jiangshan Street, passes through the underground parking lot of the Youth Olympic Center, passes through Yanshan Road, Jiangdong Road, Lushan Road and Huangshan Road, and then meets the ground of Youfang Bridge on Nanjing Ring Road. The Nanjing Youth Olympic Axis Underground Overpass Project of Jiangnan Approach Bridge was put into use in June 20 14, which is the largest underground overpass in China. The fifth Nanjing Yangtze River Bridge is located on the approach bridge between the third Nanjing Yangtze River Bridge and the Nanjing Yangtze River Tunnel. It is also the underground interchange project of Nanjing Youth Olympic Games axis, and it is the largest underground interchange in China, which is equivalent to building a three-story underground interchange. The distance from the lowest floor to the ground is 27.5m, which is equivalent to 10 floor. The whole project takes 19 months, and the total excavation area is about150,000 square meters. Construction Significance The construction of the Fifth Nanjing Yangtze River Bridge can promote the development of the Yangtze River Economic Belt, improve the layout of national trunk highways and river-crossing passages in the lower reaches of the Yangtze River, support the construction of Nanjing Jiangbei New District, and ease the traffic pressure across the river. Honors won: Nanjing Meizizhou River Crossing Project-Youth Olympic Axis Underground Transportation System and related projects won the 20 16-20 17 Luban Award for Chinese Architectural Engineering (National Quality Project).
