The Expo Axis is the main axis of the spatial landscape, people flow and traffic in the Expo Park, with a total length of about 1 1,000m and a width of about 1 1,654,38+00m. This is the largest single project in the Expo Park. It is said to be the main axis because it is located in the center of Pudong Expo Park, connecting China Pavilion, Pudong Theme Pavilion Group, Expo Center and Expo Performing Arts Center. These five buildings are collectively called "one axis and four pavilions".
Expo Axis is the main entrance and main axis of China 20 10 Shanghai World Expo, with two floors underground and two floors above ground, which is a semi-open building. Expo Axis is one of the five permanent buildings with one axis and four pavilions, and it is a large-scale commercial transportation complex integrating business, catering, entertainment, exhibition and other services. The Expo Axis is also the largest single project in the Expo Park. It was built by Shanghai World Expo Land Holding Co., Ltd., designed by German SBA Company, designed by Shanghai Huadong Architectural Design and Research Institute and Shanghai Municipal Engineering Design and Research Institute. The project is located in the center of Pudong World Expo Park, with a length of1045m from north to south, a width of 99.5m-110.5m from east to west, and a ground height of 80m. The base covers an area of 6.5438+0.36 million m, with a total construction area of 252,000 m and a total cost of nearly 3 billion, which is the sum of the Bird's Nest and the Water Cube. On February 28th, 2006, the project started at +65438 and was completed by the end of 2009.
The Expo axis and underground complex project are located in the core of the Pudong Park of the Expo. It starts from Hua Yao Road in the south, passes through Ye Xue Road, Guozhan Road, Bocheng Road and Expo Avenue, reaches Binjiang Celebration Square in the north, reaches M7 Zhoujiadu Station in the east, and reaches M8 Yaohua Road Station in the south. On the east side of the Expo axis are Shangnan Road, China Pavilion and Performing Arts Center, and on the west side are Sanyuan Road, Theme Pavilion and Expo Center, which together form the core of Siguan Park.
During the World Expo, the Expo Axis is the main axis of the spatial landscape, people flow and traffic flow in the Expo site. After the World Expo, it will become the third municipal center in Shanghai, the urban space landscape and the main axis of urban transportation, providing space for citizens' activities, commercial services and transportation transfer. The platform of Expo Axis+1-6.0m has a large tensioned membrane roof and a sunshine valley with light steel structure ... The maglev Expo Station is adjusted to the Expo Axis on the south side of the South Ring Road, and the maglev station is set above the platform passing through Expo Axis+10.0m.. Station halls are set under the platform floors on both sides of Expo Axis, which are connected with the Expo Axis+10.0 platform and pass through Expo Axis-6. The maglev station passes under the glass house of the Expo axis. The glass roof of the Expo Axis is integrated with the roof of the station.
trait
The World Expo Park will display international advanced green building design concepts such as energy saving, consumption reduction, environmental protection and ecology. The construction team, which is responsible for nearly 80% of the Expo construction tasks, has transformed and embodied the new requirements of "Green Expo" and "Hi-tech Expo" on construction technology in all aspects of the construction process, ensuring the "wonderful process and wonderful results" of the Expo construction. Huangpu river water as air conditioner
The air conditioning system of Expo Axis is different from the central air conditioning system widely used at present. The air conditioning system of Expo Axis uses the river energy of Huangpu River to provide all air conditioning energy, of which river water accounts for 70% and groundwater accounts for 30%. In summer, river water source heat pump and ground source heat pump are used as cold and heat sources of air conditioning system, which saves the supplementary water of cooling tower; In winter, river water and geographical pipeline radiators are used as high-temperature heat sources or low-temperature heat sources of heat pump systems. Generally speaking, traditional water chillers and boilers with cooling towers are replaced by river water source heat pumps and ground source heat pumps, and river water is used instead of air for heat exchange. In summer, we send hot air to Huangpu River. In winter, it absorbs heat from the river. This air conditioning system helps to reduce the urban heat island effect.
The Expo Axis is the only project in the Expo Park that uses ground source heat pump technology to integrate air conditioning cold and heat source systems. According to preliminary calculation, the replacement rate of tap water in Expo Axis is over 50%, the operating cost is lower than that of conventional air conditioning system by over 20%, the cooling water saving rate of air conditioning is 100%, and the energy saving rate of natural ventilation in spring and autumn is over 50%.

Green details
The "One Axis and Four Pavilions" of the Expo include the Expo Axis, Expo Center, China Pavilion, Theme Pavilion and Performing Arts Center. The construction team of Shanghai Construction Engineering Co., Ltd. applies the most advanced energy saving, environmental protection and ecological technologies in the world to the Expo project, making these buildings "full of wisdom".
Everyone is familiar with the "one axis and four pavilions" adjacent to Huangpu River. According to the current construction plan, in the future operation, the venues will make full use of river water sources to cool down and improve the efficiency of air conditioning systems.
On the construction drawing of a Zhang Shibo center, it is indicated that many energy-saving technologies such as solar energy, LED lighting, ice storage, river water source, ground source heat pump and rainwater collection will be adopted in the future. Every new technology will increase the corresponding construction difficulty.
In the future, the skylight at the top of the Expo theme pavilion will directly introduce sunlight, and 7,000 square meters of vertical greening will be planted on the wall to keep the wall warm. In order to achieve the goal of "no high-power air conditioning in the stadium during the day", the construction unit also set up a rainwater collection system on the roof, which was carefully constructed to let the rainwater take away the heat of the building when recycling irrigation.
Taking the Expo Performing Arts Center as an example, the construction of this project pays special attention to the use of renewable materials. In order to make an "ecological building" rise in the park, the performing arts center also adopted a "pneumatic garbage recycling system" to change the previous "high-power" operation of recycling garbage.
Science and technology highlights
In the construction stage of the permanent building of the World Expo, the builders have overcome one scientific and technological problem after another. The first lighting debugging of Expo axis in Shanghai World Expo Park.
The giant cone-shaped "Sunshine Valley" of the Expo axis is one of the highlights of the future park. But the installation of its steel structure and giant cable-membrane structure is a world-class problem.
On the Expo axis with a total length of 1.045 m and a width of about 100 m, 13 large masts, dozens of stay cables and huge curtains skillfully form the first cable-membrane structure in China and rare in the world. Six trumpet-shaped "sunshine valleys", the largest of which has an upper diameter of 99 meters and a lower diameter of 20 meters, the steel structure consists of 1, 700 units, each unit consists of 3 bars and 1 node, and the node error is less than 5 mm. ..
After repeated experiments and tackling key problems, the builders of Shanghai Construction Engineering Group finally built the "Sunshine Valley" and skillfully borrowed the "natural light" from the underground pedestrian passage of the 1,000-meter Expo axis.
This imposition photo is the first lighting debugging of the Expo axis of Shanghai World Expo Park.
Expo Theme Pavilion 1 Pavilion, without a single pillar, has a very wide field of vision and is the largest columnless exhibition space in Asia. According to the performance needs and audience capacity, the auditorium of the Expo Performing Arts Center can be selected and changed from 4,000 seats, 8,000 seats,12,000 seats and18,000 seats, and the stage can be combined in size, shape and 360 space according to the performance content. In order to complete this "change", builders are also trying their best.
During the construction of the main permanent building of the World Expo, the builders also set a new record of the heaviest hoisting of a single steel structure, the largest number of hoisting pieces in a single day and the highest hoisting tonnage in a single month. In addition, the World Expo Park, Houtan Park and Jiangnan Square, which are built with many scientific and technological achievements, will become the "green lungs" of cities with flowers in spring, shade in summer, fruit in autumn and green in winter.
Diligence concept
The construction of the Expo site is a grand event, but the concept of "running the Expo with heart" is in-depth and meticulous. Old workshops such as special steel workshop and continuous casting workshop have not been "demolished", and they will be transformed into scenic viewing places. According to the introduction of Shanghai Construction Engineering Group, according to the design requirements, the builders have begun to transform the original Pudong special steel workshop and continuous casting workshop into a landscape performance venue with an open area of11200m2-a special steel stage.
In addition, the transformed "hundred-year-old factory" Heather Water Plant will introduce international advanced water purification technologies such as high-efficiency clarifier and advanced ozone treatment, so as to provide a steady stream of high-quality water for the Expo site.
[Edit this paragraph] Architectural design
The Expo axis is not just a simple axis. It is a semi-open building, with a length of 1000 meters and a large scale. It is divided into two underground floors, the ground floor and a canopy, with sightseeing, leisure and business areas. Of course, what is more important is its barrier-free transportation function-from the aerial platform or underground passage of the Expo Axis, visitors can easily shuttle between the most important buildings in the Expo Park, such as China Pavilion, Pudong Theme Pavilion Group, Expo Center and Expo Performing Arts Center. The Expo Axis is also connected with the elevated walkway across the Pudong Expo Park, which is the transportation hub in the park, and visitors can visit different areas through it after entering the park. Expo axis
Special steel stage The special steel stage is a performance place transformed from the old workshop of the special steel workshop of Shanghai No.3 Iron and Steel Works. Located in the Expo Park in Pudong Area B, with an area of 1 1,000 square meters and an audience of 3,500 people. It is designed as an open landscape performance venue. The special steel stage presents a unique artistic atmosphere against the beautiful environment of the Pujiang River and the Expo Park. With the function of holding various celebrations and performances, the special steel stage will be the main venue for holding various major events and other large-scale theme activities.
Few people have heard of large docks, and large docks originally belonging to industrial facilities can also be used as performance venues. The 20 10 Shanghai World Expo will realize this bold idea. Area D of Puxi Garden of Expo 2010 is a protected area of Pujiang industrial site. The planning of the Expo uses the three remaining docks and two slipways to transform the surrounding part into an open square space, forming an activity venue with an area of nearly 60,000 square meters, which can accommodate 8,000 people for entertainment, recreation, exhibitions and other cultural performances. I believe that such a special stage design will leave a deep impression on visitors.
According to the plan, in addition to the above-mentioned venues, there are many venues in the Expo Park for citizens to rest and perform arts, with more than 30 large and small venues, accounting for about one tenth of the total area of the park.
[edit this paragraph] comprehensive construction
Expo axis
Since the Expo Axis project started in February 2006, it has overcome a series of design and construction difficulties, such as huge and complicated engineering quantity, adjustment of ceiling scheme, design and manufacture of "Sunshine Valley" and cable-membrane structure, construction volume of underground space and risk control. After 22 months of fighting, the underground space structure of 6.5438+0.8 million square meters has been basically completed, and the platform structure image project with a height of 6.5438+00 meters on the ground has also been completed.
The steel structure hoisting construction of the Expo Axis "Sunshine Valley" marks the beginning of the transformation of the Expo Axis construction from underground to above-ground main image project, from single project to complex project, and from single type of work to multi-type of work. It also indicates that the cable-membrane structure, glass curtain wall, electromechanical installation, ground source heat pump, river water source air conditioning and other professional projects of the Expo axis are about to enter the comprehensive construction stage.
As the largest single project in Shanghai World Expo Park, the Expo Axis covers a total area of about 6,543,800+3,000 square meters, with a total construction area of about 250,000 square meters, of which the underground space construction area is about 6,543,800+8,000 square meters and the above-ground construction area is about 70,000 square meters. The total investment of the project is about 3.5 billion yuan.
The full name of Expo Axis is Expo Axis and Underground Complex Project. It is not only the central traffic landscape axis of Shanghai Expo Park, but also the main passage connecting four permanent venues such as China Pavilion, Theme Pavilion, Expo Center and Performing Arts Center with the surrounding rail transit lines 7 and 8, and also the main entrance and exit of the Expo Park. Expo axis
It is reported that after the semi-annual Expo, the Expo Axis will develop into a multi-functional and super-large transportation and commercial complex integrating commercial services, catering, entertainment, transportation transfer and exhibition services.
[Edit this paragraph] Expo Axis-Sunshine Valley
The "artery" Expo Axis in Shanghai Expo Park has begun to take shape. On this avenue with a length of about 65,438+0,000m and a width of about 65,438+000 m, there are six inverted conical steel structures, which have great visual impact. They have a warm name, called "Sunshine Valley"-as the name implies, it is to let natural light fall at the "bottom". The World Expo Axis "Sunshine Valley" is undergoing night lighting debugging.
The six "sunshine valleys" have different shapes and sizes. Their upper opening area is equivalent to the size of a football field, with an overall height of more than 40 meters and a height of more than ten floors. The whole building is like a glass morning glory blooming quietly from the ground, crystal clear. During the World Expo, each "Sunshine Valley" will take a natural resource (flame, trees, soil, water, metal, atmosphere) as the theme, and express it through the courtyard, reflecting the blending of nature and technology. When sunlight, air, rain and other elements from the sky are introduced into the underground space by these "open flowers", the Expo axis adds a bit of romance.
In addition to visual beauty, "Sunshine Valley" also contains an important scientific and technological concept-creating a comfortable "green underground space". It not only "collects" more than 40 meters of sunlight in the air to the ground, but also transports fresh air to the ground, which not only improves the sense of oppression in the underground space, but also realizes energy saving. In addition, rainwater can also flow into the storage ditch on the second floor of the underground along these wide-mouth vase-shaped glass curtain walls, and then remit to the 7000 cubic meters reservoir, and the water can be reused after treatment. These waters will satisfy the irrigation of the sunken gardens on both sides of the "Sunshine Valley" and can be used to flush toilets. It is estimated that through the collection of "Sunshine Valley", the domestic water consumption of the Expo Axis will be halved, saving 50,000 cubic meters of water.
Will it be very hot if the sun shines directly through the glass? The Expo axis will be cooled by spraying, natural wind, Huangpu River water source and ground source heat pump. To ensure that visitors can roam the Expo axis comfortably. In addition, the "membrane structure" of the Expo axis can also play a good shading effect. These "big umbrellas" overhead are assembled by 69 huge white film cloths, with a total area of 68,000 square meters and a service life of 30 years. Although the thickness is only 1mm, the design tension has reached the highest strength in the world: 5 tons per meter. The special feature of this film is that the maximum wind swing reaches 3 meters up and down. When the wind blows, the film cloth dances like a cloud.
The steel structure and membrane structure of "Sunshine Valley" are both rigid and flexible. This state-of-the-art technology endows the Expo Axis with "gentle" humanity. The six "sunshine valleys" have more than 1000 steel structure nodes, and each node has 4-6 poles intersecting, just like an open palm. Even if there is a little error in the splicing of these nodes, the upper part of the "morning glory" can't be sealed in the end, so the requirements for building accuracy are quite harsh and have world-class difficulty. However, with the successful construction of "Sunshine Valley", this difficult node technology was once again applied to the construction of a sluice in the Expo Park on the other side of Huangpu River.
The Expo axis is divided into two floors above ground and two floors underground. When you walk in this huge passage, the sun suddenly falls in front of you, and when you look up, it will be bright. Paying attention to the way of getting along with people, nature and science and technology, "connecting heaven and earth" is the place where the Expo axis touches people's hearts. It is reported that this 280,000-square-meter building will become the third municipal center after the People's Square and Lujiazui in the World Expo.
