● Location: the construction site of Egret Stadium of Xiamen New Sports Center in Xiang 'an New Town, Xiamen.

Introduction to the interview site: Xiamen New Sports Center has a total land area of about 666,000 square meters and a total construction area of about 533,000 square meters, which is the whole city? Cross-island development? Major strategic projects can undertake top professional events such as football and track and field after completion. The center includes 60,000 stadiums, 1.8 million stadiums (supporting comprehensive training halls) and 5,000 swimming pools. Egret Stadium is the first stadium in China that can realize the conversion between professional football field and comprehensive track and field.
In the Xiamen New Sports Center of Xiang 'an New City, the Bailu Stadium recently received good news: on the 8 th of this month, the roof construction was basically completed; At the end of September, the lights were turned on for the first time, and the debugging of electromechanical system officially began. Yesterday, the reporter walked into the construction site of Egret Stadium and visited the progress of the project construction from the outside to the inside. Zero distance? Feel the construction atmosphere in full swing. The wind is full of sails, and the new city takes off. Is the construction of Xiang 'an New Town implemented by the municipal party committee and municipal government? Cross-island development? An important starting point of strategy. The headquarters of Xiang 'an New Town Area fully coordinated and promoted the construction of the new town, and the construction of the new sports center in Xiamen has now entered the sprint stage.
Wang Xufeng, Minister of Engineering and Construction of the New City Headquarters, was listening to the Party's Report to the 20th CPC National Congress before, right? Focus on promoting urban-rural integration and coordinated regional development? This sentence is particularly touching. He said that the construction of new urban areas is an important measure of urban-rural integration. Guided by the spirit of the 20th National Congress, the headquarters of the new city will implement the deployment of the provincial party committee and the municipal party committee, closely focus on the development goal of integration of people, cities and industries, continue high-standard and high-quality planning, and make every effort to build Binhai New City into a new landmark in Xiamen and contribute to the high-quality development of Xiamen's economy and society.
Outside
Scientific modeling, double guarantee of numbering accuracy and speed
Stepping on several steps and approaching the exterior wall of the stadium, we can see several construction workers assembling perforated aluminum plates on the ground. The main keel and secondary keel on the external wall have been installed in advance, and the hooks have been welded. After several aluminum plates are assembled, they will be lifted by crane, and the construction personnel will be sent to the designated position synchronously by the straight arm aerial work vehicle, and the assembled aluminum plates will be hooked to install the vertical curtain wall. Up to now, more than 90% of the 40,000-square-meter curtain wall outside the stadium has been completed, and it is expected to be fully completed by the end of this month.
Teng, a project engineer, introduced that in the early stage, the exterior wall was modeled in three dimensions, and then it was split to form a unit module, and then it was made in the factory. No module is the same, all have independent numbers, which need one-to-one correspondence. ? Even if the hook is fastened after assembly, it still needs to be calibrated and fine-tuned by total station before it can be finally completed. Every link needs careful construction, striving for perfection to fit. ?
The roof construction of the stadium, which was completed not long ago, is also full? Technology content? . The roof consists of metal roof and membrane roof, in which the membrane roof accounts for about half of the total area and consists of several tensioned membrane units. Teng Yiping said that in most areas, the inclined arch bar of the secondary keel is used to make a wavy effect, and the lower part is a steel skeleton supporting structure. Arch bars protruding from the main steel structure are made and covered with films to form a convex shape. ? We construct with flowing water, interspersed with propulsion, and ensured the accuracy and speed of construction to the maximum extent. ? In addition, because the roof is a three-dimensional distorted structure with 45,800 nodes, the construction workers accurately completed the welding and assembly of the nodes at a height of more than 86 meters.
inside
Optimized design, independent innovation, safer and more reliable.
When you enter the stadium through the aisle, your eyes suddenly become clear: the roof of the stadium is surrounded by an oval sky, and the lights shine into the stadium and are projected on the construction vehicles and workers.
The stands of Egret Stadium are designed and built according to the standards of professional football fields. The upper stand and the middle stand are cast-in-place concrete stands. The lower floor is the movable stand. Among them, the movable bracket consists of two parts: a horizontal movable inclined bracket and a vertical lifting flat bracket. As can be seen from the construction site, the diagonal stands are being assembled and made on site, and the flat stands have also been formed.
Han Xu, deputy chief engineer of the first bid section of the new sports center project, said that the mobile stands are divided into 10 blocks along the circumferential direction, and each block is a whole, which can be innovated independently through the bottom floor? Cars? , realize the overall back and forth movement; On the other hand, the bleachers draw lessons from the experience of two previous cases in the world, and adopt the method of shallow pit (without basement) lifting. Han Xu said that he was very interested in Report to the 20th CPC National Congress of the Party? Innovation is the first driving force? And then what? Enhance the ability of independent innovation? Impressive discussion? The details of independent innovation and optimized design in the construction process of these projects seem small, but they greatly enhance the safety and reliability? .
All the nights here are brightly lit, Han Xu said. Every night, our project department will organize a progress check meeting to find problems and make progress. ? At present, there are more than 2,000 workers working inside and outside the stadium at the same time, and there are more than 100 related instruments. Through reasonable deployment, under the premise of ensuring safety and quality, we will work overtime and accelerate the progress to ensure the completion of the task within the established time limit. ?
