Helong miracle! The 10,000-ton bridge pier successfully turned 83°!
2022.02.14
Recently, at the site of the cross-Beijing-Guangzhou railway project on Jian'an Street in Wuhan, with the perfect help of STC250E5-2,The 14,000-tonne pier girder of the main tower rotates 83° counterclockwise, and the east tower pier beam body "successfully hand-in-hand" to achieve the whole bridge closure.
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 adopts the upper span railway layout form of the high and low tower steel box girder cable-stayed bridge.
Because the Beijing-Guangzhou Railway is the main traffic artery of the north-south railway, the trains are busy. In order to reduce the impact on the railway,The bridge adopts the rotary construction methodFirst, the steel box girder assembly and main tower construction are carried out in the direction parallel to the railway, and then the relatively idle "skylight point" of the railway is used for rotating construction.
According to reports, as the main force of project construction,Trinity STC250E5-2craneResponsible for the hoisting of large pieces such as steel bars and platesand efficiently complete the construction task to ensure that the pier girder body of the east and west main tower is completed on schedule and with high quality.
Master Zhang, the operator of Sany STC250E5-2, introduced: "Due to the construction of other lines nearby, the surrounding residential buildings are dense, the on-site construction is coordinated and coordinated, and the geological conditions are poor.The site factors are complex, the construction period is tight, and the requirements for construction equipment are high。
For this, he highly praised Sany STC250E5-2 on-site performance. "Sany's machine has strong lifting performance, stable rotation, and dual pump and dual modes can be switched with one key.It's fast, accurate, and safe, the performance is outstanding. ”
On the same day, the pier beam body of the west main tower, with a rotating weight of about 12,000 tons, turned 105 degrees counterclockwise in place; The next day, the pier girder body of the east main tower, with a rotating weight of about 14,000 tons, turned 83 degrees counterclockwise.The two sections of the beam body smoothly "held hands in the air" to achieve the full bridge closure。
After the completion of the project, it will greatly improve the road network structure in the area and enhance the convenience of residents.
