Record the new record created by the North Square of Big Wild Goose Pagoda: the largest fountain square and the largest waterscape square in Asia, with a water surface area of 20,000 square meters; It is the largest sculpture square in Asia. There are two hundred-meter-long group sculptures, eight groups of large figure sculptures and 40 reliefs. It has the most luxurious green non-contact bathroom in the world, the cleanest, the most benches in the world, the longest light strip in the world, the world's first direct water diversion and the largest sound combination. Located in the southern suburb of Jinan, the Wild Goose Pagoda is a famous ancient building in China and is regarded as a symbol of the ancient capital Xi. Located at the foot of Big Wild Goose Pagoda, the North Square of Big Wild Goose Pagoda is 480 meters wide from east to west and 350 meters long from north to south, covering an area of 252 mu. The Big Wild Goose Pagoda is set as the north-south central axis. The front square is equipped with a mountain gate and a column tower as the connection point between Yanta North Road and the axis of the square. It consists of waterscape fountain, cultural square, garden landscape, cultural corridor and tourism business facilities. The height difference between north and south is 9 meters, divided into 9 grades, and the steps are gradually increased from south to north, forming the form of worshipping the Big Wild Goose Pagoda. The construction area of the whole project is about 1 10000 square meters, with a total investment of about 500 million yuan. Conceptually, the whole square highlights the Big Wild Goose Pagoda, Jean Temple and Tang Wenhua, and combines traditional and modern elements. There are four stone archways in the North Square, which are not only the standard primer of the square landscape, but also the signboard and landscape of the North Square. The four archways are paved with white marble, forming a three-door style with middle height and low side, showing the characteristics of balance, stability, simplicity and atmosphere. The inscription on the archway is written in the font advocated by the Tang Dynasty, and the large plaque in the middle is written in Yan Zhenqing regular script, which is magnificent; The inscriptions on the upper and lower plaques on both sides are in the calligraphy of Wang Xizhi and Wang Xianzhi, which are elegant and vivid. "Prosperous Tang Dynasty" has brought unprecedented prosperity and progress to all walks of life. This sculpture specially selected poets Li Bai, Du Fu, Cha Sheng, Lu Yu, Shi Fo, Wang Wei, Han Yu and Huai Su, calligraphers and astronomers in the fields of poetry, calligraphy, tea ceremony and medicine. Edit five mysteries of fountain in North Square of Big Wild Goose Pagoda; The largest fountain square in Asia is the largest fountain square in Asia. Anyone who has seen the fountain performance in the North Square of the Big Wild Goose Pagoda is intoxicated by its grandeur, and it has also become a new landscape in modern Xi 'an. Some people even say that they have never seen the fountain in the North Square of Big Wild Goose Pagoda and have been to Xi 'an, which is a pity. How did she become a wonderful "water dance"? How much electricity does she consume in each performance? What's the mystery under the huge fountain square? The surface is square, what is hidden underground? Secret: Underground is a "reservoir", such as a "swimming pool" as big as two football fields. When not spraying water, the music fountain is like an independent Little Square, which is integrated with the North Square of Big Wild Goose Pagoda. Looking around, the fountain square of more than 10,000 square meters is spectacular. But do the tourists who walk on it know that it is actually the "reservoir" of the fountain performance under the concrete slab about 20 cm thick at the foot? The fountain in the North Square is as big as the underground "reservoir". The fountain square on the surface is ten steps, and the length-width ratio of each step is about 50m× 25m. Projected underground, there are 10 large reservoirs with the same aspect ratio and a depth of about 1.5m (the first reservoir at the northern end is about 5m deep), which is equivalent to two "swimming pools" the size of football fields. Each pool is made of concrete and there is no connection between them. If you want to go down to the bottom of the pool, the only way is the wellhead on the surface of each step, but the premise is to empty the stored water. Recently, the fountain was overhauled, and the staff was able to lead the reporter to find out. Going down to the bottom of the pool is like being in a 1200 square meter "big lunch box". Supported by a few thick pillars, the "cover" is overhead, and the footsteps of tourists can be faintly heard. How much water can a large underground reservoir store? Secret: The storage capacity of 20,000 cubic meters is equivalent to a huge underground "reservoir" of 20 million bottles 1 liter of cola, and the daily storage capacity can reach 20,000 cubic meters for fountains. What is the concept of 20,000 cubic meters? Converted to you, it is 20 million liters of water, which is equivalent to 20 million bottles 1 liter of large barrels of coke. The average person needs to consume 1.5 ~ 2 liters of water every day, and this "reservoir" can supply at least100000 people with water every day. For the sake of visual shock, you may feel distressed with so much sparkling tap water. Actually, it is not. From the economic point of view, all fountain water is returned from Qujiang Water Plant. The water source of Qujiang Waterworks mainly comes from Heihe River. On the premise of meeting the needs of citizens, only part of the water can be discharged. This part of the water is not drinkable, but the water quality fully meets the demand of landscape water. The returned water will be led to Datang Furong Garden for transshipment and purification, and supplied to the garden and fountain square. Through the manhole cover on the west side of Fountain Square, you can see the underground water supply pipeline. After each spray, the water will flow back to the reservoir, so it can be recycled. It only needs to be filtered and dredged regularly every year, and some wastewater is discharged through pipelines to replenish new water. Water is rarely wasted unless it is evaporated during spraying. How many people are busy in each performance? Secret: A person can complete a grand performance with the click of a mouse. The observation deck at the southern end is the commanding height of the Fountain Square, and it is also a concentrated place for tourists to watch. When the fountain is open, all kinds of fancy water columns interweave into paintings and dance with the music. In fact, the "commander in chief" of this "dance drama" is the central control room quietly hidden under the observation deck. Through the password door on the east side below the observation deck, you can reach this central control room. All the "dance music", "dance form" and "dance emotion" are programmed and stored in three computers in the control room. The huge underground 108 fountain control cabinet contains power supply and frequency conversion control system, all controlled by computer. Every time it is sprayed, only one staff member needs to click the mouse to complete a grand performance. As soon as the program started, nearly 20,000 cubic meters of water woke up from a "deep sleep" and became a living "dancer". How can fountains become many shapes? Tip: The speed of the pump determines the "dance steps". More than 2000 "actors" can dance countless dances. Fountain Square has 1, 322 pumps. Each pump controls one nozzle, and there are different numbers of nozzles beside each nozzle. There are 2024 sprinklers in the whole square. When you give an order, it will produce a dancing water column. The height of the water column is completely controlled by the speed of the water pump. If the rotating speed is high, it will spray very high, up to 60 meters. At the same time, the program-controlled water pump is "intelligent". When one water column is ejected, another water column will be hit by secondary pressurization, and the two water columns will hit "fireworks" to form various "dance shapes". More than 4,000 sets of pool bottom lights changed colors under the command of the "director" to create an atmosphere. The cheerfulness of "Good Days" and the magnificence of the symphony suite of "Water Fantasy Datang" ... Nearly 200 "dance steps" procedures have different styles through different combinations. At present, in addition to the existing more than 80 tracks, the existing' dance steps' programs can also' dance' countless styles through arrangement and combination, which has great artistic potential! How much electricity does a performance need? Secret: Power consumption every 30 minutes 1000 degrees. With the largest conversion system between dry spraying and flood spraying in Asia, the musical fountain in the North Square of Big Wild Goose Pagoda is unique. Generally, fountains must be filled with water before spraying water, but in addition to this function, they can also spray water directly out of thin air on dry land without storing water. This is what we often see. When not spraying water, it is square, and people can walk in it when spraying water. Of course, the North Square can also be rebuilt, and the stepped square can quickly replenish water. In just half an hour, a number of pools are formed in the square, and dry spraying becomes water spraying, but the height of the fountain will be reduced. At the same time, the fountain can also form a waterfall-like running effect to meet people's aesthetic needs in various forms. A spectacular performance lasts about 30 minutes at a time, and consumes more than 1000 kWh. According to the calculation of 50 cents per kWh, it needs more than 500 yuan of electricity.
