After the completion of the Fifth Bridge of Xiangjiang River, all the positions on both sides of the arch of the main bridge, the cable of the arch and the approach side of the main bridge are illuminated by LED lights, which highlights the outline and outlines the unique shape of the whole bridge, like a dragon hovering with its head held high lying on the Xiangjiang River. The cable in the arch of the bridge presents a sense of rhythm of music, which makes people feel refreshed. The pier part adopts sodium lamp to cast light, which forms golden yellow lighting effect, reflecting the sense of stability at the bottom of the bridge, glittering and translucent and soft.
The greening landscape project of the Fifth Bridge of Xiangjiang River is designed according to ecology, based on rich green, and the creation of plant community landscape is pursued at both ends of the bridge. The plant landscaping is based on the diversity of species, and strives to achieve ecological and beautification functions as much as possible in a certain space. In the greening area at the bottom of the bridge, climbing plants, small shrubs, turf and other rough reinforced concrete contours are softened, which makes the bridge scenic area more ecological friendly.
The whole bridge painting project has been added to the Fifth Xiangjiang Bridge. The box girder and column of the approach bridge are painted with silver-gray dufang paint, and the collision wall of the approach bridge, the railing of the main bridge and the steel box arch are painted with white fluorocarbon paint. The whole bridge body is simple and beautiful in appearance.
Under the supervision of the owner and the supervision unit, the construction unit, CCCC No.2 Aviation Bureau, made scientific scheduling and strict management, the project quality was good, the safe and civilized construction was effectively controlled, no major safety accidents occurred, and it was completed half a year ahead of the contract period by grasping the progress. The ancient town of Jianning is still full of glory; Power Zhuzhou, a new chapter. Five bridges fly, relying on steaming people to work together; Everything goes smoothly, and everything is United. It lasted for two years and became a hundred-year plan; Gather all the talents to build a century project. Arch beam steel structure, meaning iron shoulders and morality; Intercity thoroughfare, only for business travel and people's livelihood. Connecting Beijing, Zhuhai and Shanghai, attracting phoenix to build a nest for development; Connect Zhejiang, Jiangxi, Sichuan and Guizhou, and recruit talents to build a new city. It is necessary to optimize the environment to attack the park; Urban quality improvement, but road and bridge first; Tourism heats up, relying on convenient transportation; Development stamina, in the four modernizations and two types; In Sri Lanka, you should not bear the great trust; Governing the country is the right way, and it is reasonable to care for the people. I feel a lot of comfort when this bridge is completed, which is called "the bridge to remember kindness, the bridge to connect people's hearts, and the bridge to carry forward the past and open up the future".
It's to remember.

December 26th, 2010 —— Written when the Fifth Xiangjiang Bridge (Lusong Bridge) in Zhuzhou was completed and opened to traffic.
Zhuzhou Daily Ye Xinfu Song Kai
20 10 year1February 26th is destined to go down in the history of Zhuzhou's development.
Today, the Fifth Bridge of Xiangjiang River (Lusong Bridge) was born, flying across Xiangjiang River, making the two arteries of Lushan Road and Honggang Road perfectly connected in one go, flowing through the west and east;
Today, Erhang, who is brave and good at fighting, has built another bright pearl on the "Oriental Rhine" with a record of half a year ahead of schedule, and the resounding brand of "Bridge-building Iron Army" has been confirmed again;
Today, the traffic map of "Three Rings and Seven Shoots" is a complete foregone conclusion, with the landscape bridge city of Zhuzhou, five bridges flying and the road network integrating. With smooth blood flow and endless vitality, Zhuzhou has entered the fast lane of a new round of scientific leap.
Scientific scheduling, opening to traffic six months in advance.
The beautiful Xiangjiang River, which runs through the city, has made Zhuzhou's unique charm.
Bridge, witness the footsteps of Zhuzhou, an ancient and young city, speeding up, from Zhuzhou Bridge to Shifeng Bridge, Jianning Bridge, and then to Tianyuan Bridge, Zhuzhou galloped all the way.
Bridge, like a "living child" in a chess game, is full of brilliance when the pieces fall. The municipal party committee and municipal government assess the situation, forward-looking positioning the bridge construction as a key project to promote leap-forward development, making strategic arrangements for catching-up progress and leap-forward development, and constantly accelerating the pace of traffic facilities construction. On September 29th, 20071/KLOC-0, the groundbreaking ceremony was held for the Fifth Bridge of Xiangjiang River. On May 18 of the following year, the project officially started construction.
The Fifth Xiangjiang Bridge is invested and constructed by CCCC Second Waterway Engineering Bureau Co., Ltd. (referred to as the Second Waterway Engineering Bureau). The bridge type is a three-span arch beam steel structure combination system, starting from Tianyuan District in the west and connecting with Lushan Road. East to Lusong District and connected to Honggang Road, the main line of the whole bridge is 2,495.6 meters long, of which the total length of the main bridge is 182 1.6 meters, the main bridge is 33 meters wide and has six lanes in both directions. The estimated total investment of the project is 70.1billion yuan, and the construction period is 36 months.
In the past three years, with the strong support of the Second Aviation Administration and relevant departments of Zhuzhou City, the Xiangjiang Fifth Bridge Project Department has overcome the rare natural disasters of ice and snow, the low water of Xiangjiang River and the delay of demolition, carried forward the spirit of "striving for scientific and technological leadership and creating first-class management", meticulously organized, scientifically managed, strictly programmed and civilized, carried out pioneering projects in party member, labor competitions, striving for harmonious projects and other activities, and comprehensively and smoothly promoted the bridge construction.
Urban development, traffic first. At the end of 2009, according to the needs of the rapid development of urban construction, Zhuzhou Municipal Government reached an agreement with No.2 Aviation Administration, requiring the Fifth Bridge to be opened to traffic six months in advance, which was included in the government work report.
Under the pressure, the Fifth Bridge Project Department quickly adjusted the construction plan, increased the investment in personnel, materials and equipment, signed letters of responsibility layer by layer, carried out labor competition and implemented the progress reward and punishment system on the premise of ensuring quality and safety. The enthusiasm of all the staff was high, all the work was accelerated in an all-round way, and the plan was overfulfilled one after another. The construction period of the hanging basket was shortened by 4 days on average, and the main bridge was closed six months ahead of schedule, ensuring that the whole bridge was opened to traffic at the end of the year, half a year ahead of the expected target.
The rainbow flies down the Xiangjiang River, and the new city rises in the present. After the opening of the Fifth Bridge, together with Tianyuan Bridge, Jianshe Road and Changjiang Road, it will form the inner ring of the city, share the traffic pressure in the central area of the city, improve the urban traffic environment, and will effectively promote the construction of a harmonious and ecologically livable Zhuzhou.
Strategic choice, continuous three-degree cooperation
"The Fifth Bridge of Xiangjiang River has continued the good cooperative relationship between the Second Navigation Bureau and Zhuzhou City." Zhang Junsheng, project manager and party branch secretary of Xiangjiang Fifth Bridge, said.
The strategic cooperation between Zhuzhou City and No.2 Aviation Administration has a long history. The first project is the lock project of Zhuzhou Navigation and Power Hub. Subsequently, the Second Navigation Bureau built the first BT project in Zhuzhou-the Fourth Xiangjiang Bridge (Tianyuan Bridge). This bridge has created the fastest record in the history of bridge construction in Zhuzhou, and won the 2007 Quality Engineering Award in Hunan Province.
The Fifth Bridge of Xiangjiang River is the second BT project, which is still invested and built by the Second Navigation Bureau. After completion, Zhuzhou City will buy it back by means of government procurement and installment payment.
"An important reason for choosing No.2 Navigation Bureau to build the Fifth Xiangjiang Bridge is that there was no quality and safety accident during the construction of the Fourth Xiangjiang Bridge." On February 17 last year, Chen Junwen, secretary of the Municipal Party Committee, visited the construction site of the Fifth Xiangjiang Bridge again, telling him to ensure the quality and safety, and asked the relevant departments to give full support to create a good environment for the project construction. Wang Qun, deputy secretary of the municipal party committee and mayor, visited the site of Xiangjiang Fifth Bridge for many times to learn about the project progress, quality, civilized construction and safety production.
For Zhuzhou, No.2 Aviation Administration is a trustworthy partner. Founded in 1950, No.2 Navigation Bureau is a wholly-owned subsidiary of China Communications Construction Co., Ltd., a fortune 500 enterprise, and has the special grade of general contracting for highway engineering construction.
The first-class qualification of general contracting for port and waterway engineering construction and general contracting for municipal public works; More than 200 docks of various types have been built, and nearly 100 bridges across rivers and seas have been built and participated in; In the construction of Jiangyin, Wuhan Junshan, Ehuang, Runyang, Wuhan Yangluo and other Yangtze River bridges, many bridge construction records in China have been created, and the world's largest span cable-stayed Sutong Yangtze River Bridge, the world's longest cross-sea bridge Hangzhou Bay Bridge, and the world's largest span steel truss arch bridge Chongqing Chaotianmen Yangtze River Bridge have been built.
In contrast, among many large-scale projects attracting worldwide attention in the Second Navigation Bureau, the Xiangjiang Fifth Bridge project with an estimated investment of 7. 1 100 million yuan can only be regarded as a small project. However, from the date of project preparation, the leaders of No.2 Aviation Administration and the four companies responsible for construction paid special attention to this, and listed the project as the seventh of the "Top Ten Projects" this year to ensure its completion and opening to traffic this year.
On March 9th this year, Wang Haihuai, general manager of the Second Navigation Bureau, once again came to the Fifth Bridge Project Department of Xiangjiang River to check the progress of the project, and asked to ensure that it was opened to traffic in advance at the end of the year. We also discussed the further deepening of cooperation between No.2 Aviation Administration and Zhuzhou City and the investment in the construction of the Sixth Xiangjiang Bridge.
Exquisite skills, three major difficulties
If you want to realize a dream, you should make it round without regret.
During the construction, the No.2 Navigation Bureau introduced advanced technology, which continuously overcame the key points and difficulties in the construction of large-diameter pile foundation, V-brace and basket-carrying box arch, so as to ensure the construction quality of the bridge and benefit the people of Zhuzhou.
One of the difficulties: construction of 3.5m large diameter pile foundation.
The 3 1# and 32# at both ends of the highest arch of the bridge are the main bearing piers, and 8 rock-socketed piles with a diameter of 3.5m shall be arranged under each pier. It is the first time to drill such a large pile foundation by drilling technology in No.2 Navigation Bureau. For this 16 pile, the project department invested more than 2 million yuan and specially purchased 3 drilling rigs. After many demonstrations and careful construction, the project department broke through the technical difficulties of super-large diameter underwater bored pile foundation and successfully poured it to a depth of 28 meters, achieving the goal of high quality and safety.
The second difficulty: curved thin-walled prestressed V-brace construction.
V-brace, that is, the V-shaped main pier in the water, is like a pair of open giant arms to support the main body of the bridge, with beautiful appearance, but the technology is quite complicated and the construction is very difficult. The project department has invited experts from all sides to hold a plan review meeting for many times, and repeatedly scrutinized every step to be foolproof. From the first concrete construction on February 22, 2009, which lasted more than four months, the project department successfully solved many problems such as curve, thin wall, prestress and rigid skeleton in V-brace construction, and successfully completed major construction nodes.
The third difficulty: the installation of the basket box arch.
The basket box arch is three arcs arched on the bridge deck. The arch rib of the main bridge is a basket-box arch with an inclination of 3.814. The rise of the main arch is 30 meters, the rise of the side arch is 18 meters, and the maximum segment weight of the arch rib of the main span is 70.2 tons, which is another big test for construction. After demonstration, the construction workers processed the arch rib into small sections in the factory, transported it to the top of the box girder, then spliced it, and then installed it with gantry crane, successfully overcoming this difficult technical problem.
In the past three years, the project department has used advanced technology and exquisite technology to overcome technical problems and captured engineering nodes, turning the Fifth Bridge of Xiangjiang River from a blueprint on paper into a flourishing boutique standing on the Xiangjiang River.
Harmonious project, build a monument.
Yesterday morning when I went to work, Zhang Junsheng, secretary of the project department, once again walked on the bridge and made a careful inspection from west to east. It has become his habit to patrol regularly every day.
"Since the start of construction, there has not been a quality and safety accident in the Fifth Bridge Project." Zhang Junsheng proudly said that at the beginning of construction, the project department started the "Harmonious Project" in accordance with the requirements of "carrying forward the spirit of the Second Aviation Company, striving for a harmonious project, and building the Fifth Xiangjiang River Bridge to benefit the people of Zhuzhou", striving to achieve the "Five Zero" goals of zero quality defects, zero safety accidents, zero risk management, zero service and zero cases of clean government, and building the Fifth Xiangjiang River Bridge into the owner's peace of mind, the government's peace of mind, the supervisor's peace of mind and leadership.
A century-long plan, quality-oriented. From the start of construction, the project department will decompose the target responsibility for the quality management of the bridge, refine the quality management, implement the responsibility to people, and link it with rewards and punishments. The project department will also conduct random checks with the owner and supervisor from time to time, from raw materials entering the site to construction site control, from scheme approval to calibration of various instruments, from concrete appearance control to data collection in the industry, and conduct all-round inspection of quality management.
People-oriented and safety first. The Fifth Bridge is a municipal super-large bridge, located in the downtown area, across the main roads of the city, and it also needs to carry out three-dimensional crossing operations on water, land, high altitude and underground, so the safety issue is even more important. In order to ensure construction safety, the project department set up a special organization and formulated a series of safety production guarantee systems and rules and regulations, forming a good atmosphere in which everyone values safety.
In order to support the work of creating sanitation and civilization in Zhuzhou City, the Fifth Bridge Project Department strictly manages and carries out civilized construction, and keeps the construction site orderly for a long time. The office and living quarters are civilized and tidy, which has been praised by the party and government leaders and local colleagues in Zhuzhou City for many times. The Project Department has been rated as a safe and civilized construction site in Hunan Province for two consecutive years.
Do a project, create a brand and build a monument. The civilized and safe construction of Xiangjiang Fifth Bridge Project Department has set up a banner in Zhuzhou construction market, which has been widely praised by Zhuzhou Municipal Party Committee, Municipal Government and the general public. Zhuzhou Municipal People's Government awarded the title of "Bridge-building Iron Army" to No.2 Aviation Administration, and Hunan Provincial People's Government awarded the title of "Advanced Construction Unit of Provincial Key Construction Projects" to the Project Department.
Centennial Bridge, Xiangjiang River as a witness. Dare to fight and fight, skilled five-bridge construction iron army, in the Millennium Xiangjiang River, added a touch of bright color to the brand Second Airlines; In Zhuzhou, a new industrial city, a solid platform of "ensuring two and striving for one, and leaping forward scientifically" has been poured, which has ignited the infinite reverie of Zhuzhou people for a better tomorrow.
