Especially the undulating curved roof of the cultural and sports center, which has not yet been completed, has attracted many citizens to come and check in.
When he saw a bright moon hanging in the middle of a tower crane, He Jianjia’s spiritual light flashed: the tower crane was very fixed and had a height similar to that of a building.
The plan to set axis control points was forced to be abandoned.
If the benchmark was set on the floor hastily, it would affect the measurement and judgment of contour lines.
If benchmark points were placed on it, it would not only be unobstructed but also facilitate data measurement and reading.
Such a huge construction area and cumbersome measurement and control points are rare in China.
After making up his mind, He Jianjia customized scale paper with pasting function from the manufacturer and climbed up the tower with the measurement team leader Zhou Ban, setting benchmark points one by one.
“Looking at the news of the French President’s visit to China popping up on his phone, Fan Ganlu, the project manager of the Wuhan Sino French Ecological City project of the Second Aviation Administration, confidently said.
After losing the first battle, He Jianjia pondered on his own until late at night.
After the placement test, its measurement accuracy and transmission signal have been greatly improved
.
The hyperboloid area of the Cultural and Sports Center is 4000 square meters, and there are nearly 10000 detection points to be established.
To achieve precise measurement and control, the project department has formed a research team led by He Jianjia, Deputy Chief Engineer of the Testing Center of the Sixth Branch.
However, the unique design poses a huge challenge to the surveying and mapping team.
He Jianjia thought of setting axis control points on buildings, reserving transmission holes at corresponding positions on each floor, and projecting relevant data to any floor through elevation transmission or laser plumb method.
If there is an error in the data, the clothes produced will definitely not fit, “Fan Ganlu metaphorically said.
If President Macron can visit the Sino French Ecological City, he will be amazed by the rapid changes in this world.
The more complex the building structure, the more precise the measurement and control data support is needed, just like making clothes requires’ tailoring ‘.
Due to its unique political significance and beautiful expectations, located in the hometown of a soulmate, Cai Dian, the design concept of “encountering a soulmate in high mountains and flowing water” runs through the entire Sino French ecological city.
After completion, it will form a 12 minute cultural and sports circle, promoting the ecological city to become a model of livable and business-friendly urban development.
The friendship between China and France is long-lasting, and cooperation in the field of infrastructure also has a long history.
Wuhan Sino French Ecological City is a sustainable ecological demonstration new city jointly constructed by the two countries.
However, after setting nearly a hundred benchmark points, it was found that the signal was extremely unstable.
After multiple reviews, He Jianjia found that there were obstacles on the first and second floors of the building, and the curved roof on the third floor was a frame beam structure without columns.
Remembering the initial difficulties, the project team still remembers them vividly.
The core area of the project is a single 80000 square meter cultural and sports center.
