【Hop Dragon Miracle! 】 Recently, at the site of the Wuhan Jian'an Street Cross-Beijing-Guangzhou Railway Project, with the perfect help of STC250E5-2, the 14,000-ton east tower pier beam body rotated 83 degrees counterclockwise, and the main tower pier beam "successfully held hands" with the main tower pier body to achieve the whole bridge helong.
The project is a three-span steel box girder cable-stayed bridge with a total length of 519.3 meters, of which the main bridge is 245 meters long, and the high and low tower steel box girder cable-stayed bridge is arranged on the span railway.
Because the Beijing-Guangzhou Railway is the main artery of north-south railway traffic, the number of trains is busy. In order to reduce the impact on the railway, the bridge adopts the rotary construction method, first in the direction parallel to the railway, the steel box girder assembly and main tower construction are carried out, and then the relatively idle "skylight point" of the railway is used for the turnaround construction.
According to reports, as the main force of project construction, Sany STC250E5-2 crane is responsible for the hoisting of large pieces such as steel bars and plates, and efficiently completes the construction task to ensure that the east and west main tower pier beams are completed on schedule and with high quality.
Sany STC250E5-2 operator Master Zhang introduced: "Due to the construction of other lines nearby, the density of surrounding residential buildings, the coordination of on-site construction, poor geological conditions, etc., the site factors are complex, the construction period is tight, and the requirements for construction equipment are high.
To this end, he highly praised the sany STC250E5-2 on-site performance. "Sany's machine has strong lifting performance, stable rotation, and double-pump dual mode can be switched at one button, that is, fast, precise, safe, and the performance is very outstanding."
On the same day, the west main tower pier beam with a rotating weight of about 12,000 tons was turned counterclockwise 105 degrees in place; the next day, the east main tower pier beam with a rotating weight of about 14,000 tons was rotated counterclockwise at 83 degrees, and the two beams smoothly "held hands in the air" to achieve the whole bridge.
After the completion of the project, it will greatly improve the road network structure of the area and enhance the convenience of residents. #Construction Machinery Brand Network # #工程最前线 #
