The new landmark of Chengdu is Bamboo Shoots 2165438+1October 24th, Chengdu Giant Panda Research Base, where a 69.8m-high "Bamboo Shoots" stands-this is a new landmark of Chengdu with the design concept of "Bamboo Shoots Break Ground, Hibiscus Bloom": Chengdu Panda Base Sightseeing Tower. As the commanding height of Chengdu Panda Base, the tower is like bamboo shoots that have sprung up from the ground, and it is the first building in China to adopt the concept of "Meng". The watchtower on the 1 1 floor is equipped with an elevator, and it takes about one minute to reach the top of the "bamboo shoot tip". Visitors can get a panoramic view of the panda after climbing the tower!

It is understood that the tower is about 69.8 meters high, with a construction area of about 5,900 square meters, with one floor underground and nine floors above ground. Among them, 1~9 floors will present multiple spaces such as dynamic stage, panda theater and art museum to meet the different needs of tourists of all ages. Panda, bamboo shoots, hibiscus flowers ... a brand-new panda-themed landmark, superimposed and mixed with a series of Chengdu elements, is "budding".

BIM technology for weaving "steel bamboo shell"

The bamboo shoot modeling of sightseeing watchtower requires the tower body to present a smooth modeling of "small on the top and large on the bottom", so the steel structures used in the construction process are mostly arc members, and the dimensions of each layer are different, which puts forward extremely high production accuracy requirements for the construction team. China Wu Ye adopts the most advanced BIM technology in the industry, collects and converts the coordinate data of the "bamboo shell" part of the sightseeing tower, that is, the steel mesh shell, and establishes the three-dimensional coordinate axis network of the installation site.

At the same time, the key points of each number are measured and set by total station, and the key positioning points such as coordinates and axes of each curtain wall connector between different axes are determined to ensure the installation accuracy of "steel bamboo shell".

8 1 piece of "hibiscus petals" constitutes a 360-degree viewing platform.

As a new scenic landmark in this area, the Sightseeing Tower will face the "339 TV Tower" far away after completion. Each observation deck of the tower presents a lotus petal shape, and 8 1 petal observation deck * * * makes Chengdu another panoramic scenic spot.

In order to ensure the uniqueness of each "hibiscus petal", the project team must pay off in advance, deepen the drawing mold opening before production and processing, conduct three-dimensional simulation positioning for each installation node, guide the on-site pay-off work, and improve its accuracy and construction efficiency. At the same time, coordinate control network is established to eliminate errors, and total station and various measuring instruments are used to ensure the accuracy of coordinate points.

Ingenious mechanism to design the posture of "germination"

The top of the sightseeing tower is another unique place. The tower crown is usually closed, and it will only be opened at important time nodes such as the birth of a baby panda, the birthday of a star panda, and legal holidays, showing the posture of' spring bamboo shoots'.

The tower crown intelligent dynamic opening and closing system consists of 84 bars, and the longest bar length is about 20 meters. To ensure the perfect opening of the tower crown, it is necessary to ensure that the opening dynamics of these 84 rods are consistent. Therefore, the project department adopts hydraulic system to realize the opening and closing action. In the process of opening and closing, each bar is added with a displacement sensor, which is controlled by proportional adjustment, so that the opening and closing effect and speed requirements of each bar can be accurately met.

In addition, crescent-shaped steel members welded with steel plates will be used as the keel of the bar, and the appearance of the bar will be decorated with aluminum plates and aluminum profiles to ensure its firmness and stability under wind pressure and high temperature.

The new landmark in Chengdu is Bamboo Shoots 3165438+1the morning of October 24th 10. A 69.8-meter-high "Bamboo Shoots" stands in Chengdu Panda Base, which is a new landmark in Chengdu with the design concept of "Bamboo Shoots Break Ground, Hibiscus Bloom": Chengdu Panda Base Sightseeing Watchtower.

The relevant person in charge of China Wu Ye Group introduced in an interview that the sightseeing watchtower built by Wu Yecheng of China has been successfully completed and accepted recently.

How was this 69.8-meter "big bamboo shoot" built? What are the wonders?

Standing on the "bamboo shoot tip" can overlook the whole panda base.

Why build "bamboo shoots"? On the one hand, it is because giant pandas love bamboo shoots, on the other hand, it means "bamboo shoots break out of the ground".

So, what is this "bamboo shoot"?

As the commanding height in Chengdu Giant Panda Base, the 69.8-meter-high watchtower looks like a bamboo shoot from the south side of the tower and looks like a "cut bamboo shoot" from the north side of the tower.

Wen Yuan, head of the sightseeing observation tower project of Chengdu Panda Base in Wu Ye, China, introduced that the "steel bamboo shoot shell" of the whole building is in the shape of "small on the top and big on the bottom", weighing 1.300 tons, and is woven by 720 steel arc members with different shapes.

"The size and inclination direction of each steel structure member are different, so each member is individually customized and unique, which is extremely difficult to manufacture and install." Wen Yuan introduced that before the components are manufactured, each component is "tailored", and BIM technology is used to repeatedly calibrate and calculate, and the accuracy is strictly controlled; In the installation stage, the ground assembly should be carried out in small units and the errors should be carefully calibrated. After meeting the standards, several cranes should be used for smooth hoisting to ensure seamless installation.

How did the 69.8-meter-high "spring bamboo shoots" climb to the top? According to Wen Yuan, the watchtower on the 1 1 floor is equipped with an elevator, and it takes about one minute to reach the top of the "bamboo shoot tip".

"Standing on the tower, you can not only overlook the panoramic view of the panda base, but also see Chengdu landmark buildings such as 339 TV Tower and Shufeng 468. In the future, the tower will also serve as a landmark landscape building of Chengdu Panda Base for tourists to visit and punch in. " Wen Yuan said.

This is the first building in China that adopts the concept of "budding"

This is a budding "big bamboo shoot", and the secret lies in the "bamboo shoot tip" part of the 69.8-meter-high watchtower.

A 75-member opening and closing system is installed at the top of the sightseeing tower, with the longest length of18m-it is understood that this is the first "building" in China that adopts the concept of "budding".

According to Wen Yuan, each bar is equipped with displacement sensors to accurately meet the effect and speed requirements for "sprouting" and closing within two minutes. "The tower crown of the sightseeing tower is usually closed, but at important nodes such as the birth of a giant panda baby, the birthday of a star panda, and legal holidays, the tower crown will be gorgeously opened."

It is not easy to achieve "germination". "During the installation and debugging of the tower crown, the project team perfectly cooperated with the precise positioning and installation of steel structures, hydraulic devices and electrical devices, ensuring the high consistency of the opening and closing actions of 75 bars." Wen Yuan said.

The "bamboo shoot tip" is amazing, and the "bamboo shoot body" is also full of realistic effects.

According to reports, in order to simulate the texture and vein of the surface of the "spring bamboo shoots" to the greatest extent, in the decoration stage, the project team * * * adopted nearly 672 curved crescent window grilles that did not repeat the single song, and woven the full-arc curtain wall coat of the "spring bamboo shoots". Among them, the size and shape of each grille are different. The maximum grille length is13.688m, and its self-weight exceeds 600kg.

At the same time, in order to better restore the "bamboo shoots" landscape, we also pay attention to painting, coloring and other details. The light brown outer grille glows with reddish golden luster in the sunset, and the steel structure frame wrapped with golden glass fiber reinforced plastic shows the natural beauty of the building.

8 1 golden petals carry 8 1 high-altitude viewing platform.

Entering the Panda Sightseeing Tower is another scene.

From the bottom up, pieces of "hibiscus petals" are blooming beautifully-this corresponds to the 8 1 observation deck of the Panda Sightseeing Tower.

Bamboo shoots germinate and hibiscus blooms. "8 1 golden clusters of' hibiscus flowers' create amazing visual experience." Luo Cheng, the construction manager of the sightseeing watchtower in China Wu Ye Panda Base, introduced that these "hibiscus petals" are manned platforms of the sightseeing watchtower, and 8 1 platforms are gradually distributed inside the watchtower with a total floor of * * *1. Each platform adopts Chengdu hibiscus petal shape, which can provide tourists with sightseeing and rest services.

At the same time, in order to create the most perfect sensory effect, the ground of the viewing platform is made of "golden millstone" made of terrazzo technology, and the railings around the platform are bamboo-shaped, showing ingenuity in every detail.

Luo Cheng also introduced that in order to achieve the golden landscape effect, the project team conducted many "one-on-one proofing" tests, and finally selected two kinds of fluorocarbon paints that matched each other. The selection of materials not only pays attention to the color and luster, but also considers the use characteristics of the project itself and the ultra-high environmental protection requirements.
