After 4 consecutive days of highest-level first-class blockade construction of the railway, at 5:20 a.m. on December 21, the elevated steel structure of the east station building of Lushan Station of the Anjiu Railway successfully completed the precise beam falling, marking the successful completion of the world's first large-scale station to transform the steel structure of the overall cross-line beam construction.
The total width of the steel structure of the east station building of Lushan Station is 176 meters, the total length is 90 meters, the total weight is 4,300 tons, and the covering area is 15,840 square meters, which is equivalent to the size of 38 standard basketball courts.
In the process of falling the beam, the self-developed 156 project management digital intelligence construction platform and the telescopic davit device of the railway catenary were adopted, and the on-site 3-level command system, 245 operators, and 30 sets of equipment were carried out synchronously and graded, which not only realized the dynamic control of the entire site personnel, machinery, materials, construction progress, etc., but also completed the complex and precise beam falling action within the limited "skylight point".
It is understood that Lushan Station is the reconstruction and expansion project of the existing passenger station, which is the first in Jiangxi Province and the second in the country "up in and out" high-speed rail station, the station building is divided into two phases of construction, the west station building has been opened for operation, and the east station building will start construction in May 2022. The construction of the falling beam of the elevated steel structure of the east station building of Lushan Station has been completed to fill the gap of efficient and safe construction of large-scale station buildings on the busy railway trunk line. After the completion of the falling beam, the east station building of Lushan Station will enter the construction stage of the main structure. After the completion and opening of the reconstruction and expansion project of Lushan Station, it will further release the new function of Jiujiang as an important node city in the Yangtze River Economic Belt and promote the economic and social development of the middle and lower reaches of the Yangtze River.
