summary

brief introduction

Expo Axis is the main axis of space landscape and people traffic in the Expo site, with a total length of about 1000 meters and a width of about 110 meters. It is the largest single project in the Expo site. It is 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 on the left and right. These four buildings are collectively known as "one axis and four Pavilions".

underground complex

The Expo Axis and underground complex project is located in the core of Pudong Park. It starts from Yaohua Road in the south, crosses Xueye Road, Guozhan Road, Bocheng road and Expo Avenue, reaches Binjiang Celebration Square in the north, connects with China Art Palace Station of Rail Transit Line 8 in the East and Yaohua Road Station of rail transit line 7 and 8 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 Yuansan Road, Theme Pavilion and Expo Center, which together form the core of the park with one axis and four pavilions.

characteristic

Green details

The Expo "one axis and four Pavilions" include the Expo Axis, Expo Center, China Pavilion, Theme Pavilion and performing arts center. The construction team of Shanghai Construction Engineering Group makes these buildings "full of wisdom" by applying the most advanced energy-saving, environmental protection and ecological technologies in the world to the Expo project.

We are all familiar with the fact that "one axis and four Pavilions" are close to the Huangpu River. According to the construction plan, in the future operation, the pavilions will make full use of the water source of the river to cool down and improve the efficiency of the air conditioning system. Only one construction drawing of the Expo Center indicates that solar energy, LED lighting, ice storage, river water source, ground source heat pump, rainwater collection and other energy-saving technologies will be used in the future. Every new technology will increase the difficulty of construction.

In the future, the skylight on the top of the Expo Theme Pavilion will directly introduce sunlight, and 7000 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 daytime", the construction unit also built a rainwater collection system on the roof, and carefully constructed, so that the rainwater can take away the heat of the building when it is recycled for irrigation.

Taking the World Expo Performing Arts Center as an example, the construction of this project pays special attention to the use of renewable materials. In order to build an "ecological building" in the park, the Performing Arts Center also adopts a "pneumatic garbage collection system", which changes the "high-power" operation of garbage collection in the past.

Technology highlights

During the main construction stage of Expo permanent buildings, one technological problem after another has been overcome by the builders. The huge cone-shaped "Sunshine Valley" of the Expo Axis is one of the highlights of the future park. However, the construction and installation of its steel structure and giant cable membrane structure is a world-class problem.

On the Expo Axis with a total length of 1045 meters and a width of about 100 meters, 13 large masts, dozens of stay cables and huge curtain skillfully constitute the first cable membrane structure building in China and rare in the world. There are six trumpet shaped "Sunshine Valley", the largest of which is 99 meters in diameter above and 20 meters in diameter below. Its steel structure is composed of 1700 units, each unit is composed of three members and one node, and the node error is less than 5 mm.

After repeated trials and tackling key problems, the builders of Shanghai Construction Engineering Group have finally built the "Sunshine Valley", which enables the pedestrian path of Expo Axis to borrow "natural light".

There is no pillar in Pavilion 1 of the Expo Theme Pavilion, which is the largest pillar free exhibition space in Asia. The auditorium of the Expo Performing Arts Center can be selected from 4000 seats, 8000 seats, 12000 seats and 18000 seats according to the performance needs and audience capacity. The stage can be combined in three dimensions according to the size, shape and 360 ° space of the performance content. In order to complete this "change", builders are also working hard.

During the construction of the main permanent building of the Expo, the builders also set a new record of the heaviest single steel structure lifting, the largest number of lifting pieces per day, and the highest lifting tonnage per month. In addition, the Expo Park, Houtan Park, Jiangnan square, etc., which are constructed with a number of scientific and technological achievements, will become the "green lungs" of cities with "flowers in spring, shade in summer, fruits in autumn and green in winter".

The idea of diligence and thrift

The construction of the Expo site is a big scene, but the concept of "diligence and Thrift" is in-depth and meticulous. The former special steel workshop and continuous casting workshop and other old workshops have not been "pushed down and started again", they will be transformed into landscape style performance viewing places. Shanghai construction engineering group revealed that according to the design requirements, the builders have begun to transform the original special steel workshop and the old plant of continuous casting workshop of Pudong Iron and Steel Co., Ltd. into a landscape style performance viewing place with an open area of 11200 square meters - special steel stage.

In addition, through the introduction of international advanced water purification technologies such as high-efficiency clarifier and ozone activity advanced treatment, the reformed "centenary factory" Nansha water plant will provide a continuous stream of high-quality water for the Expo site after it is completed and put into operation.

scale

idea

In the design of Expo Axis, the concepts of ecology, environmental protection and energy saving are fully introduced, and new technologies of environmental protection and energy saving are largely adopted, such as introducing green, fresh air and sunlight into each floor space through Sunshine Valley and grass slopes on both sides; at the same time, ground source heat pump, river water source heat pump, rainwater collection and utilization are used. It is reported that the rainwater collected by Sunshine Valley is stored in the basement floor. After treatment, it can be used for irrigation and cleaning, and effectively save water resources.

The Expo site will display the world's advanced green building design concepts of energy conservation, consumption reduction, environmental protection and ecology. The construction team, which undertakes nearly 80% of the construction tasks of the Expo project, transforms and reflects the new requirements of the "Green Expo" and "science and Technology Expo" on the construction technology in all aspects of the construction process, so as to ensure that the "process is wonderful and the results are wonderful" of the Expo project construction.
