Project introduction
The Sixth Xiangjiang Bridge in Zhuzhou (also known as Fengxi Bridge) is one of the major infrastructure projects in Zhuzhou during the Twelfth Five-Year Plan period. A total of 6 sets of bridge design schemes/kloc-0 were completed, which were reviewed by experts at the end of March and publicized in the planning exhibition hall at the beginning of April.
Zhuzhou Xiangjiang Sixth Bridge is located between "middle" Jianning Bridge and "inner ring" Tianyuan Bridge, 2.5 kilometers away from Jianning Bridge in the upstream and 3.8 kilometers away from Tianyuan Bridge in the downstream. The bridge starts from Huanghe South Road in the north and ends at the intersection of Hangkong Avenue and Quchi Avenue. South across binjiang road, Xiangjiang River, Jiang Yan Road and Tianchi Road planned in Lusong District, and finally around the river, it is a fast river crossing channel between Hexi City and Hedong Fengxi Eco-city and Aviation New City. The Sixth Xiangjiang Bridge has a total length of about 1729.4 meters, a main deck width of 32 meters, six lanes in both directions and a design speed of 50 kilometers per hour. According to reports, according to the principle of "one bridge and one scene", the Sixth Bridge will become a landmark building in Zhuzhou City.
The overall construction of the project includes bridge engineering, road engineering, drainage engineering, lighting engineering, greening engineering, traffic engineering, municipal pipeline engineering, other public facilities and land acquisition and demolition. The length of the whole bridge (main bridge, approach bridge and tie lines at both ends) is about 1729.4m, and the length of the bridge part is 1429m. The main bridge is 570 meters long and the approach bridge is 859 meters long. The bridge is 32 meters wide and has six lanes in both directions. The main bridge is planned to be a self-anchored suspension bridge with two towers and a main span of 300 meters.
The total investment in the preliminary design of the project is 790 million yuan, and the construction period is three years. It is expected that 20 16 will be completed and opened to traffic.
Fengxi Bridge in Zhuzhou, Hunan Province was completed and opened to traffic in 20061October 20th1KLOC-0/65438. The deck of this bridge adopts ultra-high toughness concrete composite structure, which is the first application of suspension bridge in the world.
Scheme approval
The main bridge type of Xiangjiang Sixth Bridge has been approved by the Municipal Planning Commission a few days ago. Three years later, the "Rising Sun" will rise in Zhuzhou section of Xiangjiang River.
16 scheme "rising sun" finally won.
In order to ensure the optimization of the bridge type scheme of the Sixth Xiangjiang Bridge, Zhuzhou Planning Bureau and Chengfa Group organized Shanghai Municipal Engineering Design and Research Institute, China Communications Second Highway Survey and Design Institute and Hunan Provincial Traffic Planning Survey and Design Institute to design the bridge type scheme in March, 201/. * * * Complete 6 sets of bridge design scheme/kloc-0, organize expert review at the end of March, and publicize it in the planning exhibition hall at the beginning of April.
From April to May this year, based on the selection of half-through arch bridge by experts, the Municipal Planning Bureau organized three original design institutes and Tianjin Municipal Engineering Design and Research Institute to innovate and improve the original scheme, and completed three sets of improved schemes and four sets of creative schemes.
On June 8th, the Planning Committee preliminarily selected three schemes, namely "Rising Sun", "Blooming Flowers" and "Rough Waves". Compared with the two schemes of "bloom in the River" and "Waves", the bridge designed by the scheme of "Rising Sun" has many advantages. From the structural point of view, this scheme is simple in structure and simple in overall modeling. From the construction point of view, the foundation of this scheme is on both sides of the river, the construction is less affected by the water level, the standard of the upper steel box girder is high, and the production and installation are simple. From the point of view of navigation and flood discharge, the main bridge in this scheme adopts the structure of "90m+400m+90m", which will not affect navigation and flood discharge. In addition, the cost estimate of 830 million yuan is also the lowest among the three schemes.
After synthesizing the opinions of experts and the masses, the "Rising Sun" scheme was finally approved by the Municipal Planning Commission because of its profound conception, clear structural stress, magnificent momentum, simple overall shape and modern minimalist style.
Features of the scheme: There is a 700-square-meter sightseeing platform on the bridge. According to the "Rising Sun" scheme, the Sixth Xiangjiang Bridge is a long-span arch bridge, the main arch curve is in harmony with the surrounding environment, and the arch ribs are steel box arches with simple lines, which reflects the modernity with the overall effect. The arch ribs of the bridge are smooth, natural and full, just like the rising sun, which means that Zhuzhou is like the rising sun with unlimited potential. The curve of the bridge arch is full, smooth and beautiful, and the radians of the upper and lower arch ribs are different. Control the arch bridge in a relatively full state, which is more in line with the theme and makes the shape of the arch ribs complete.
Due to the large size of the arch rib, the bridge will probably refer to Shanghai Lupu Bridge, and a pedestrian ramp will be set in the middle of the main rib to provide a leisure area that is very suitable for tourists to visit and nearby residents to walk. In addition, the 700-square-meter sightseeing platform at the top of the tower can be transformed into a sports area, a leisure area and even a gathering place according to needs, which is of great use value.
Project process
20 12 65438+ from the end of February:
According to reports, the Provincial Transportation Planning Survey and Design Institute has been entrusted to prepare the project proposal and feasibility study report. It is planned to complete the project approval and feasibility study approval in September, complete the design bidding in June 5438+ 10, complete the preliminary design in June 5438+10, organize the construction in supervision bidding with the preliminary design in June 5438+February, and hold the groundbreaking ceremony at the end of the year.
Opened in 20 16:
Li Jie, the sixth bridge office of Chengfa Group, introduced that the sixth bridge of Xiangjiang River was tentatively named Fengxi Bridge, with a construction period of about 4 years. It is expected that the 20 16 bridge will be completed and opened to traffic.
Project importance
Upon completion, Zhuzhou Xiangjiang Sixth Bridge will be connected with Tianchi Road, Hangkong Avenue and Wanshou Road, and connect Tianyuan District and Lusong District, which is a fast river crossing channel between Hexi City and Hedong Fengxi New City, Hangkong New City and lukou town of Zhuzhou County. It will become a fast river crossing channel between Hexi and Hedong Fengxi New Town, Aviation New Town Area and lukou town in Zhuzhou County, which will play a positive role in optimizing the urban road network structure and expanding the urban development space.
