To the east of West Lake, on the bank of Qiantang River, the huge silver-white roofs undulate like waves, as if another West Lake has emerged from the sky. This is the T4 terminal of Hangzhou Xiaoshan International Airport that is being prepared for operation. It is a key guarantee project for the Hangzhou Asian Games. It is also the civil aviation terminal with the largest contract value for a single bid section in China.
html On July 13, the People's Daily published an article "The Hangzhou Xiaoshan International Airport Phase III Expansion Project Integrating Civil Aviation, High-speed Rail, Subway, and Public Transport Enters Operational Sprint - Green Intelligence Embodying Scenery", reporting on China Construction Eighth The builders of the Hangzhou Xiaoshan International Airport project of the Bureau overcame numerous challenges such as non-stop construction, tight construction schedules, heavy tasks, and the impact of the epidemic, and conquered a number of key technologies in innovation, safety, and emission reduction to promote project construction efficiently, quality, and safely.
"After it is put into operation, this will become one of the largest airports in East China and a new door to the country welcoming visitors from all directions." Looking at the terminal building rising day by day, China Construction Hangzhou Xiaoshan International Airport Phase 3 Project Management Judi Qiang, general contracting project manager, is very proud. “This large-scale comprehensive transportation hub integrating civil aviation, high-speed rail, subway, and public transportation is integrated with the scenery, green and intelligent, and will also drive the high-quality development of the airport economy.” . ”
The new terminal shows the elegance of Hangzhou
The area is nearly twice as large as the three old terminals combined
The total investment of the third phase expansion project of Xiaoshan Airport reached 27.1 billion yuan, ranking at the forefront of national airport investment. The total construction area is approximately 1.5 million square meters, including T4 terminal, comprehensive transportation center, high-speed rail station, energy center, etc.
"The investment in T4 terminal alone is nearly 10 billion yuan. It is currently the domestic civil aviation terminal project with the largest single-bill contract value. Its total area reaches 720,000 square meters, which is larger than the previous three terminals. The combined total is nearly twice as big," said Chen Hua, chief engineer of the third phase of the airport's new terminal project.
Why build such a big terminal?
Chen Yi, director of the Design and Technology Department of the Airport Phase III Headquarters, explained that the original terminal of the airport can cater for 33 million passengers per year, but it exceeded 30 million as early as 6 years ago and has become saturated. With the rapid growth of civil aviation transportation demand, it is urgent to build a new terminal. A large number of passengers need to be collected and distributed and connected to rail transit. A new comprehensive transportation center that "goes to the sky and reaches the ground" can bring more convenient travel services.
Walking in the newly built T4 terminal, you feel like you are in the beautiful West Lake where "the lotus leaves touching the sky are infinitely green, and the lotus flowers reflecting the sun are uniquely red". In the waiting hall, which is as large as 14 standard football fields, 32 "lotus leaf columns" with staggered heights stand upright from the sky. The huge "lotus leaf" umbrella spreads out and turns into a softly curved roof.
"Although it is made by man, it seems to be made by nature." Judi Qiang said that the interior of the airport means "Landscapes of Hangzhou, ten new sceneries", and there are many West Lake paintings hidden inside. "For example, the six check-in islands are shaped like ancient sailing boats, like 'boating under lotuses.' Look at the carpets, which are dotted with osmanthus-like patterns, which is the 'fragrance of osmanthus rain.' The most recognizable one is the airport landmark 'Lotus Valley.'" ', the steel structure column with a height of more than 50 meters blooms into a huge lotus on the roof, creating the effect of 'hibiscus emerging from the water'."
To build such a beautiful and huge project, the project team overcame many challenges.
The first is non-stop construction. The expansion project is close to the old terminal and cannot affect civil aviation operations.
Secondly, the construction schedule is tight and the tasks are heavy. "The construction period of most projects of the same scale is more than 48 months, and the construction period of our terminal is 39 months, which is the shortest among similar projects. During the construction sprint of the terminal building alone, tens of thousands of people were involved in the battle, and two people were involved every day. Work shifts without stopping," Chen Hua said.
In addition, due to the strict implementation of epidemic prevention and control regulations, the project encountered serious challenges such as foreign materials and workers being unable to enter. The relevant departments promptly dispatched special vehicles and opened green channels, which gradually alleviated the difficulties.
"In March this year, the project completed five parties' completion acceptance. In May, civil aviation acceptance was organized. Overcoming numerous difficulties and dangers, the airport construction exceeded the 'Hangzhou speed'." Chen Hua said.
Overcame a number of key technologies during construction
Set a new record for a single lift of the national airport terminal roof
The third phase expansion project of Xiaoshan Airport is one of the ten landmark projects in the construction of "Grand Channel" in Zhejiang Province. In order to set an industry benchmark, the project team devoted a lot of energy in innovation, safety, emission reduction and other aspects, conquered a number of key technologies, and won the first in the country.
Similarly, the upgrade of the steel roof grid of the first section of the T4 terminal has also set a new record for a single upgrade of the domestic airport terminal roof. The roof that can be lifted at a time covers more than 20,000 square meters, which is equivalent to more than 50 standard basketball courts. It weighs more than 8,000 tons, which is comparable to 40 medium-sized passenger aircraft. It is realized through computer-controlled hydraulic synchronous lifting technology. In this type of difficult construction, the project team has successively conquered 13 key technologies.
Energy saving and emission reduction, reducing building energy consumption. From the beginning of the design of the new terminal, the project team worked hard on "green". "The terminal uses many passive energy-saving technologies." Pan Junjun, deputy chief engineer of the airport's third-phase new terminal project, said that the metal roof is covered with radiant cooling film, which can reflect solar radiation and cool the interior; the roof skylights are also used for lighting. Analysis, effectively reducing electric lighting; automatically controlled windows can adjust natural ventilation according to the temperature to improve comfort.
After being put into operation, it will create multiple benefits
The airport's software and hardware will be improved simultaneously, radiating and driving the airport economy
stimulating investment, upgrading services, and attracting high-tech industries... After the third phase expansion of Xiaoshan Airport, it will not only make transportation more convenient, but will also bring benefits to Hangzhou and even the rest of the world. Surrounding areas continue to create multiple economic and social benefits. During the construction period of
, the investment volume of the third phase expansion project was huge, with a daily output value of tens of millions of yuan. After the three phases of the project are all put into use, the T4 terminal will be able to serve 50 million passengers every year, which will provide more efficient civil aviation transportation support for the Yangtze River Delta region.
hardware upgrade also led to service improvement. Chen Yi introduced that with the goal of building a "four-type airport" that is safe, green, smart and humanistic, Xiaoshan Airport will become one of the comprehensive transportation hubs with the shortest transfer distance and the most convenient. Passengers can achieve paperless passage from entering the terminal to the boarding gate, and are provided with humanized services throughout the process. For example, the security check can be cleared quickly by "swiping your face", and the "zero height difference" equipment can be used for check-in, so there is no need to laboriously carry luggage. There is also a "self-out basket" system that automatically pushes luggage baskets to passengers. The new terminal also adds many new airport seats, further improving travel happiness.
Looking at the long-term benefits, the expanded airport hub can radiate and drive the airport economy and attract more industries to gather. "The airport international cargo terminal project with a total investment of 2.4 billion yuan has been successfully capped. Enterprises such as Cainiao and YTO are accelerating the construction of cross-border e-commerce and smart logistics development bases to enhance the aviation logistics supply chain." Zhejiang Hangzhou Airport Economic Development Co., Ltd. Deputy General Manager Dai Zhongxin said.
On April 13 this year, Hangzhou Linkong Economic Demonstration Zone was officially unveiled. biomedicine , digital trade, aviation services...an airport industry cluster formed around Xiaoshan Airport is growing. Taking biomedicine as an example, more than 30 industrial projects have been launched, covering the entire industry chain such as leading companies and incubated companies. Not long ago, Airport Economic Demonstration Zone ushered in the signing of ten major projects, including sales of duty-free goods, pediatric drugs, industry-university-research cooperation, etc., with a total investment of 3.33 billion yuan.The airport economy is making great strides, and the future is promising.
