3D printing technology is the first application of Xinjiang construction field
In the movie "The Zodiac", the protagonist wears special gloves to move on the first of the Yuanmingyuan copper beasts. After getting the data into the computer, an identical copper beast is "baked out". This is the 3D printing technology . Nowadays, 3D printing technology has been applied to the construction of the North Square of the High Speed ​​Rail New Passenger Station. This technology is the first time in the field of construction in Xinjiang.
On December 23, the author saw in the interview that the four shape-specific “Eye of the Eyes†on the sunken square in the North District of the High-speed Railway New Passenger Station have taken shape. These four “Eye-Eye†are made of 3D printed materials. . Xiong Binhui, manager of the engineering project department of the High-speed Railway Hub Comprehensive Development and Construction Company, said that the unique “Eye-Eye†design on the sunken square of the North Station of the New Passenger Station is a bright spot, and the “Tianyan†building materials are manufactured by 3D printing technology. After the installation of the "Eye of the Eyes" model is completed, it will present a realistic eye shape, and will form an integral whole with the above-ground buildings and sunken squares. The smooth curve expression will become a beautiful scenery of the North Square of the New Railway Station.
According to reports, because the "Eye of the Eyes" shape of the building is a complex three-dimensional arc shape, the traditional construction process is difficult to complete, the high-speed rail development company introduced the new 3D architectural printing technology, the production of SRC board (steel reinforced concrete structure) into a roof Curved shape, this new process has the characteristics of smooth appearance, beautiful lines and high strength. The representative of the square construction party Song Feng said that each "sky eye" has 1200 positioning points, the most difficult is the accuracy of the positioning point. After repeated research, the total station positioning and auxiliary cable are finally used for comprehensive measurement and positioning. The positioning of the first point must be seven or eighty times to be accurate. The deviation of each point can not be greater than 3 mm. It took more than 20 days to complete the positioning of the four "eyes".
“The SRC board is bolted, so it can be repaired and replaced in the future,†Song Feng said. According to reports, the four-day 3D printing installation "eyes" model is expected to invest 24.65 million yuan, has invested more than 12 million yuan, completed 50% of the project volume, is expected to be fully installed on June 30, 2016.
