On May 24, the Wuhan New City Exhibition Center was located in the central area of the new city, which is part of the Optical Valley East Digital Economy Industrial Park。

More than 2,000 builders fought hard on Optics Valley Science Island, Optics Valley East Digital Economy Industrial Park, and the construction of the "seven horizontal and seven vertical" skeleton network accelerated in an overall way...In the early summer, Changjiang Daily reporters visited Wuhan New City in depth to witness the city that does not rest day and night, and every day is different。

"The construction of Wuhan New City is an important development opportunity and a major historical responsibility for Wuhan。On January 5, 2023, the Wuhan Government work report made it clear that the construction of Wuhan New City was started with high standards。On January 31, the major project of Wuhan New City was launched, starting 175 projects with a total investment of 166.5 billion yuan。A week later, the Wuhan New City plan was released。Up to now, the key project library of Wuhan New City has gathered 205 projects of more than 100 million yuan, with a total investment of 4,376.44亿元。

The machines are roaring, the cranes are standing, everything is hot。Across the mountains, surrounded by nine lakes, across the two cities of Wuhan and Ezhou, 719 square kilometers of Wuhan New City is from the dream to the reality step by step。

■ Three shifts in construction

The infrastructure lifeline is expected to be completed ahead of schedule

In January this year, in the core area of Wuhan New City, the innovation source base laid the first pile, which also marks the official sound of the construction of Wuhan New City, and the main engine of high-quality development of Wuhan metropolitan area was ignited。

May 26 at 6:30 in the morning，The sky is white，Optics Valley Science Island future road integrated pipe corridor project site，Zhang Jingyang, the construction director of the project, started on time to do the subject every day - counting personnel and safety propaganda before the class，With an order，150 day shift workers entered their posts，Start construction tasks for the day。

At the same time, the first complex project of Optics Valley Science Island Science Center phase I project site, 650 workers ready to prepare, after the project chief engineer Zhou Wei finished the morning shift of the new day, in an instant, in the four main structure has been capped and one will be capped in the building, the sound of the construction "symphony".。

Not far from the core science and technology Industrial Park project site, cement mixing trucks have been rumbling。With 700 workers working in three sections, 40 night shift workers who had been pouring concrete overnight in the second section had a break。

Optics Valley Science Island Future Road, Gaoxin 7 Road two integrated pipe corridor project, started in November last year, the current future one integrated pipe corridor is carrying out the internal support and pipe corridor main structure construction, Gaoxin 7 Road pipe corridor is carrying out the crown beam and the first concrete internal support construction。In order to ensure that the civil construction part is completed by the end of this year and the equipment installation can be opened next year, some teams of the construction team will implement three shifts to accelerate the construction of the project。

In order to coordinate the main structure and the handover of the buried unit's work face, Zhang Jingyang was busy until 12 p.m. the previous day。Zhang Jingyang said that the entire project management team members have hardly taken a vacation since they returned to work and resumed production during the Spring Festival this year。

This year's "May Day" holiday is the first birthday of Zhang Jingyang's daughter。On April 30, Zhang Jingyang had just returned from Wuhan to his hometown in Jingzhou, when he received a notice from the company: in order to speed up the construction of Wuhan New City, the two pipe corridor projects need to be completed in advance, and all project personnel must return to work immediately。

"The task is urgent, and the deadline is the order。Like a 100-meter sprint athlete, Zhang Jingyang ran to the street to buy a birthday cake for his daughter and food and drinks for the family banquet。At 11:30 that night, he rushed back to the project site to organize the project organization and deployment meeting。At this point, just six hours had passed since he received the notice。

Meng Weiwei, project manager of Zhuxin Science and Technology Industrial Park, also gave up his vacation。This Spring Festival, in order to complete the node target task of the integrated circuit industry showroom by the end of March, the project construction team stuck to the project for 7 days to optimize the construction and carry out the final sprint。

With a total construction area of about 800,000 square meters, the Optics Valley Core Science and Technology Industrial Park project, with a total investment of about 6.5 billion yuan in the first and second phases, is positioned as a pan-semiconductor research and development pilot base, and the layout of a national innovation center and integrated circuit industry exhibition hall。Overlooking the construction site of the first phase of the industrial park, the golden roof of the integrated circuit industry exhibition hall is like a huge chip。

Meng Weiwei is a native of Dandong, Liaoning province. In 2020, after leaving Shenzhen Investment Holding Group, he joined Optical Valley Kejin Construction Company, a subsidiary of Optical Valley Financial Holding Group, to participate in the overall planning and promotion plan of the core Industrial Park project。As a project manager, he "nailed" on the project almost every day, taking the site as his home, eating and living on the site。"The more holidays we have, the more we can't relax。Meng Weiwei said。

In order to speed up the construction progress, Zhang Jingyang and his colleagues thought of many ways。Fan Fengtao, the chief engineer of the project, said that the most afraid problem of the underground pipe gallery is water leakage. The project adopts the innovative construction process of pre-laying back bonding method, the material is made of polymer nanomaterials, and the waterproof protective layer is not played, which greatly saves the construction period。

The construction pace has been accelerated in an all-round way, and the construction of the section surface has been changed from the previous section flow operation to the excavation of the whole line and the whole section surface at the same time, and the existing section surface materials have been supplied at one time。In order to avoid the rainy season affecting the construction period, the project team changed the construction process from traditional excavator construction to long-arm excavator and grab construction, which was not affected in rainy days and also saved a lot of time for the project。

A few months later, these two integrated pipe corridors, which are invested by Hubei Science and Technology Investment and built by China Construction Third Bureau, are expected to usher in water, electricity, communication and other pipelines in advance。

"The integrated pipe corridor integrates all kinds of trunk pipelines such as water supply and drainage, recycled water, power, and communication for unified planning, construction and management, which is an important basic guarantee for the operation of the central area of Wuhan New City, and is the infrastructure 'lifeline' of Optics Valley Science Island."。Qin Jun, secretary of the Party Committee and chairman of Hubei Science and Technology Investment Group, said that the implementation of the project will promote the intensive development and utilization of regional transportation, ecological environment and underground space, and lay a solid foundation for the construction of world-class scientific and technological innovation policy source highland。

Also expected to speed up further is the science and Innovation center。Last August，Hubei Ketou Optics Valley Science Island Company Science and technology innovation Center project was issued the province's first set of construction engineering construction permit, municipal facilities construction approval (urban road occupation excavation permit), urban sewage discharge into the drainage network permit, urban construction waste disposal approval and other "four certificates in one" comprehensive construction project license，The construction of the project is progressing rapidly。

Up to now, the four buildings of the Science and Innovation Center project have been capped and more than half of the masonry has been completed。The project is expected to be completed by the end of June next year。

Standing on the Optics Valley Science Island, looking around, the backbone network has been connected into a ring, a factory building, an industrial park is rising, it is hard to imagine that not long ago, here was a piece of barren smoke and grass。

Currently, 16 science Island in Optics Valley.On 8 square kilometers of red land, more than 2,000 builders are comprehensively promoting the construction of projects in many fields such as infrastructure, park construction, pipeline relocation, power distribution network, and people's livelihood public construction。According to the person in charge of Hubei Ketou Optical Valley Science Island Company, the company has carried out 33 construction projects in the Optical Valley Science Island area, and has completed an investment of about 4.3 billion yuan。

■ Construction next door is in full swing

Companies have signed up to move in here

At 3 PM on May 24, from the floor glass of the first floor of the Wuhan New Town Exhibition Center, the Green Axis Park and Sports Park near the mountain and the water saw the scale for the first time, and appeared particularly lush under the sun. An egret was not affected by the concrete mixing truck, and lightly swept across the water, drawing a long water mark。

"The pavilion and the landscape have become one piece。Although every one or two days to go to the site to turn around, Tan Xu, general manager of Huarong Company of Liantou New City Group, was delighted to find "new changes".。

Wuhan New City Exhibition Center is located in the central area of the new city, which is part of Optics Valley East Digital Economy Industrial Park。The project is invested and constructed by Liantou New City Group and constructed by Liantou Hubei Road and Bridge Group. With the design theme of "Ascending Yuntai", the project integrates planning and display, product release, roadshow meeting and administrative services. After completion, it will become the external platform and investment exhibition window of Wuhan New City。

The whole exhibition center is divided into three parts, underground and above ground, a total of five floors。Among them, the roof of Huarong Hall is a large-span steel structure, and the tower floor is surrounded by a rotating split-level structure。"All are steel structures, there are more special-shaped structures, and the construction is very difficult。"Wuhan New City exhibition center project manager assistant Shao Mingming said。

Shao Mingming, a native of Jiujiang, Jiangxi province, joined LiANTou Hubei Road and Bridge Group after graduating from Wuhan University with a major in civil engineering. This is the first large-scale steel structure building he has participated in。"The construction period is tight and the task is heavy。Shao Mingming recalled that since the start of the project in October last year, he has stayed on the site almost every day, and will take a leave to go back to his home in Hanyang for ten days and a half months to briefly accompany his pregnant wife。Go home at night and be back in the morning。

This sense of urgency can be found almost everywhere。Standing in the open space of the project to accept the interview in a short time of more than 20 minutes, Shao Mingming answered seven or eight phone calls, answering a variety of project-related matters。On the large steel structure behind him, the propaganda banner is prominently hung, which reads "quality and safety go hand in hand, efficiency and speed go hand in hand", "truth and pragmatism speak efficiency, big dry fast catch progress" and other colorful slogans。

In order to complete the delivery of the project by the end of June, more than 120 workers on the site worked hard。"Construction was still under way at 10pm and there was no stoppage during the Chinese New Year。Shao Mingming's dark face can hardly hide fatigue, "This is the window of Wuhan New City to display, the platform for investment promotion, to complete the quality and quantity, and put into use as soon as possible.。”

"It's very stressful。Unlike Shao Mingming, in Tan Xu's view, the project volume and construction difficulty of the Wuhan New Town Exhibition Center are not large, "mainly the construction period is short, a process is not completed, and another process is up, which is a great challenge.。However, the greater pressure does not come from this。He drew a circle in the air with his finger, "In this 4 square kilometer area, more than 50 projects are moving forward simultaneously."。

"4 square kilometers" refers to the Optics Valley East Digital Economy Industrial Park (formerly Honglian Lake Big Data Cloud Computing Industrial Park), which was officially launched in October 2020.。As a provincial key industrial project created by Ezhou City and Hubei Joint Investment，The industrial park is located at the intersection of the central area of Wuhan New City and the Honglian Lake area，Starting point of Ezhou section of Optical Valley Science and Technology Innovation Corridor，Adjacent to national memory base，The future will be the most closely linked with the core industrial chain of Optical Valley，To undertake the industrial resources and scientific and technological resources spillover from optical Valley。

20 roads, two pavilions, two parks, schools...Tan Xu knows all the projects under construction in the park，According to him，Except Wuhan New Town Exhibition Center，Several roads in the park were constructed at the same time，The primary and middle schools of Honglian Lake Future School are scheduled to be put into use in September this year，The high school starts construction simultaneously，North core Green Axis park, sports park is stepping up construction，"How to meet the deadlines，Smooth progress of all projects，It is a great test of the ability of internal coordination and intensive management."。

如今，Nearly 1,000 days have passed since the first shovel of soil was dug in the exhibition center of the industrial park，More than 300 days have passed since the Ezhou section of the Future Three roads connecting Wuhan Future City and Optical Valley East Digital Economy Industrial Park was officially opened to traffic，In the core area of Wuhan New City，A digital economy industrial park has taken shape。

January of this year，The launch of major projects in Wuhan New City and the first quarter of major projects in the province's Huarong District branch venue was held in Optics Valley East digital Economy Industrial Park，Twelve intelligent manufacturing projects, including optical communication, equipment production base, and core and micro intelligent manufacturing, were started，These projects are optical Valley "optical core screen end network" trillion industrial cluster strong chain extension chain supplement project。

While building, while putting into use。CAI Weiwei, deputy general manager of Ezhou Technology Park Company of Donghu High-tech Group, which is responsible for the construction of the park, introduced，Up to now，Nearly 10 companies, including Xinfeng Optoelectronics and UnionPay Big Data, have signed up to settle in，"Concentrated in big data, cloud computing, optoelectronics and intelligent manufacturing industries，Many are for Huaxing photoelectric and Yangtze River storage to do supporting"。

"When I first came, the winding country road, the material could not be transported in, and it could not be turned out for one or two hours, and now I can drive around the park in ten minutes.。Tan Xu proudly said, "We have truly witnessed this overgrown land become a modern new city.。”

■ More than 1,000 steel pipes

No two are alike

New city construction, traffic first。At present, the construction of the "seven horizontal and seven vertical" skeleton network in Wuhan New City is accelerating in an all-round way, and the key projects such as the renovation project of Gaoxin Avenue, Danzulihu Bridge, Gaoxin Three Road and Gaoxin Seven Road are showing rapid changes。

"High-altitude work，Be safe!Helmets and seat belts must be worn according to regulations!"On the morning of May 25th，Chen Lifeng, project leader of Wuhan Optics Valley Construction Investment Co., LTD., called all construction personnel for safety education，Urge participating units to implement grid unit management system，Make safety work "life"。Subsequently, he and the person in charge of the participating party went to the "Pearl of the Valley of Light" at the intersection of the Shanghai and Chongqing Expressway in the future to check the installation of the stainless steel curtain wall of the bridge tower dragon skeleton。

The Future First Road (Science North Road - Science and Technology Five Road) project has a total length of 1015 meters, which is an important north-south main road of Wuhan New City。Among them, the "Pearl of Optics Valley" bridge tower has a total height of 75 meters, which means the core industry of Optics Valley Science Island - life health and photoelectric information, and the vibrant "new leaves" on the left and right sides hold up the "crown pearl" of Wuhan New City, indicating that the development of Optics Valley Science Island is as bright as a pearl。

Chen Lifeng introduced that the project was officially launched in May last year, and the construction content includes road upgrading, bridge width, new slow bridge and a unique shape of the "Pearl of Light Valley" bridge tower。

Li Hanzhou, deputy chief engineer of the municipal machinery Company of Chengfa Group, which has been engaged in many domestic key municipal projects for 22 years, just entered the project when he saw the drawings, his first reaction was: "How is it so complicated?？Each steel pipe is completely different shape and weight, and how to accurately lift in a complex construction environment is a "hard bone".。

"You see, the cutting surface of these steel pipes is round and square, concave and convex, each one is cut out separately, and it took a full 2 months to cut the steel pipe alone.。Li Hanzhou said with a smile that more than 1,000 steel pipes are "identity" - with a unique number plate, and during the installation process, the steel pipes are "special management position".。

Chen Lifeng introduced that Optical Valley Construction Company, municipal machinery company and Wuhan University of Technology cooperated to set up a research project research group, and tailor-made an industrial software and launcher for "Optical Valley Pearl"。"Three-dimensional laser scanning is used to calculate the spatial coordinates of each component, the signal transmitter is installed on the segment that needs to be lifted, and the relative spatial position is monitored in real time during the lifting process.。Li Hanzhou explained that as a landmark building in Wuhan New City, the "Pearl of the Valley of Light" in addition to its own structural modeling is novel, and it also makes full use of various new technologies in the construction process, and no fewer than 5 intelligent manufacturing software are used。

Tong Fei, a 34-year-old Chongqing native who has been in the construction industry for 15 years, is a young veteran who can do both welding and installation。"My record is more than 10 keel welds in one day!"There was a certain pride in his speech，"After coming to this project，The biggest feeling is' the heart is tired '!"How did it take more than half an hour to figure out how to fit this keel，We have to go back to the next one，"Practice doesn't make perfect，This is the first time I've met in so many years."。

Tong Fei said: "Although can not rely on experience, but I figured out a set of methods, get started relatively fast, do faster, hope to finish the project early with quality and quantity.。”

Although one is a viaduct and the other is a cross-lake channel, like the "Pearl of the Valley of Light", the "infinite bridge" known as the Short Zulihu Bridge is also "out of the circle" because of its unique shape, which is expected to become another landmark in Wuhan New City。

Shorzuili Lake Bridge is the main cross-lake channel connecting Wuhan and Ezhou。At the beginning of last year, the bridge renovation project (Wuhan section of Gaoxin Avenue - Ezhou section of Gaoxin Avenue) began, widening from the original two-way 6 lanes to two-way 8 lanes, which is also the "hard Unicom" transportation hub project in Wue。

"It is expected to complete the overall structure by the end of September and realize the traffic within the year.。According to Hu Zheng, the project leader of Wuhan Optics Valley Construction Investment Co., LTD., the current transformation project of the Short Tsui Lihu Bridge has completed all the substructure construction, and is carrying out the erection of steel beams and the construction of the south bridge deck。The reporter saw at the scene that the orange-red steel structure above the main bridge stood tall and was about to usher in two arch ribs。

"This is a great highlight of our design!Take "unlimited" as the idea，Reference is made to the concept of "infinite ring - Mobius ring"，Embody "internationalization, sense of technology, sense of the future"，The two arch ribs of the main bridge are connected in space，Form the symbolic image of infinity '∞' in mathematics，On behalf of Wuhan New City infinite possibilities and open development of the broad mind。Hu Zheng introduced that another highlight of the bridge on both sides of the new 2 meters wide sidewalk and 3 meters wide non-motorized lane, not only convenient for residents to commute to and from, but also to enjoy the beautiful lake view on the bridge, "more highlights the" home city "characteristics of Wuhan New City."。

In the past one and a half years, Wang Chunguang, site technical director of the China Railway Bridge Bureau, the project contractor, has encountered a lot of difficult work。"The project is close to Metro Line 11, and the pile foundation is relatively close to the subway。From safety considerations, Hu Zheng and Wang Chunguang led a 23-person project team to come up with a full protection cylinder plan, equivalent to putting on more than 40 meters of protective cover from head to toe for the pile foundation to prevent the soil layer from collapsing to the middle。

Even more difficult is how to make the steel deck seamless。

At about 5 PM on May 25, Sun Guiyang, a 40-year-old man from Xuzhou, Jiangsu province, slowly poked his head out of the steel beam box, holding an empty 4-liter kettle in his hand. After taking off the mask, a bald skin appeared on the bridge of his nose。

Big water bottle is the "standard" of Sun Guiyang and his workers。Every morning, filling a full pot of cool water, wearing a gas mask, he and his team members began a day of welding work - using an electric welding machine to fill the gap in the middle of the steel bridge floor, the more flat the better。Sometimes it is done on the bridge floor, and sometimes it is necessary to go down to the steel beam box to do internal welding。

No matter how hot the weather is, you have to wear long pants, long sleeves, and then wear full gear to go underground。The pungent smell produced by welding operations, mixed with the hot air, makes people feel hot and uncomfortable。Sun Guiyang smiled and said: "There is no hard work to make money.？Work well done, it is worth it!"What he is doing is an important step in making the steel deck seamless。

On the bridge floor, Hu Zheng led the workers to lay the neoprene rubber sheet。"It mainly plays the role of sealing and waterproof。Xu Zhaokun, head of the project production, said as he squatted down and gently pressed the rubber sheet laid in the morning with his hand, "There is a little empty drum here, and it needs to be repaired.。”

After this process, the ultra-high performance concrete of 120 MPa will be used to pour the joint of the new and old bridge, so that the connection of the new and old bridge surface is not only smooth, but also more ductile and stronger, "when the vehicle passes through the intersection, it can not feel the bumps", Xu Zhaokun introduced, which is another highlight of the project。

Xu Zhaokun, 34, was involved in the design and construction of the first urban metro project in Kuala Lumpur, Malaysia, which was his first project after returning to work in China from Malaysia。"It's very meaningful。"He said with a smile。

At present, the "Pearl of the Valley of Light" bridge tower has been hoisted, and the next step is to assemble the spire, beam and "Pearl of the Valley of Light"。Hu Zheng said: "The structure is expected to be completed by the end of June and completed by the end of July, two months ahead of the original schedule.。This also means that two months later, the new landmark on the central axis of Wuhan New City will officially welcome the citizens who "punch the card"。

Around 10 p.m., the lights in Mr. Lee's room stay on -- several technical files are open simultaneously on his computer, and he looks at the problems he has jotted down in his notebook during the day while devising a new construction plan。

Li Hanzhou, with a team of 12 project technicians, resided at the project site。His son is in the third grade and hasn't seen his father for a long time。Li Hanzhou sometimes sends photos and videos of the project to his son, who says excitedly, "Dad, what a beautiful bridge you built!"I'm going to see it。”

The transformation project of the lake bridge has also entered the final stage, and the construction units and construction units have riveted their full energy to rush the construction period。Hu Zheng, Xu Zhaokun and other people have to patrol the site every day, check the implementation of the progress plan, keep an eye on the production progress, quality, safety and civilized construction of each site, and coordinate the allocation of project construction personnel, materials and machine resources。

"The last time I went home was half a month ago, I don't know if my daughter still knows me.。Xu Zhaokun has a daughter less than 1 year old at home, although the opportunities to get along with the family are few and far between, but fortunately his wife is very supportive of his work, "When the child is older, I will tell her father was building a very powerful bridge.。”
