At 5:00 a.m. on May 24, the largest station building on the Anjiu High-speed Railway, Lushan Station East Station Building, which was designed by the Fifth Railway Institute and undertaken by China Railway Construction, successfully completed the first steel structure push-up, marking the world's first large-scale station building renovation steel structure spanning The first push of the line was successfully completed. This push created four world records for the largest width, the largest weight, the largest area, and the largest number of slide rails in the cross-line pushing construction of the station renovation project.

Lushan Station is located in Jiujiang City, Jiangxi Province. It is an existing passenger station reconstruction and expansion project. It is an important transportation hub on the main artery of the Beijing-Kowloon Railway. It has been opened for operation on April 28, 2022, and the construction of the east station building will start in May 2022.

The steel structure of the east station building pushed this time is composed of 5 units including the waiting floor truss, transfer corridor and overpass, with a total width of 176 meters, a total length of 90 meters, a total weight of 4,300 tons, and a coverage area of 15,840 square meters, which is quite In 38 standard basketball courts. For the first push, under the synchronous action of 10 sets of hydraulic numerical control pushers, the steel giant pushed forward 26 meters and successfully straddled the four tracks of the Changjiu Intercity.

The construction of the East Station House spans 10 tracks including the Changzhou-Kowloon Intercity Railway, the Beijing-Kowloon Railway, and the Wuhan-Kowloon Railway. Among them, 6 main operating lines run through the construction site of the second phase of the Lushan Station, and the operating lines cannot be shut down for a long time to make concessions Construction, which requires that the design and construction must find another way to minimize the impact of construction on railway transportation. The project team used the bridge jacking construction technology to push the main structure to the design position. The width of 176 meters also set a new record for the largest width of the same type of jacking in my country.

This push is a secondary blockade and needs to be carried out at the 4-hour night skylight point. In the early stage, the project team used Midas professional steel structure software, BIM technology, and 156 project management digital intelligence construction platform to provide technical support for the push, from force analysis, detailed implementation plan, simulation push analysis to solve difficulties, real-time full-angle monitoring Make full preparations for monitoring the situation on the spot.

There are 180 staff members in 5 groups including command, operation, safety, protection and logistics at the push site to provide all-round support for the push. In order to ensure the safety of railway operation, the project team invited a team of external experts to jointly analyze and verify the scheme from multiple angles, combined with the actual situation on site, conducted as many as 11 studies and demonstrations, and finally adopted the segmental production in the factory + on-site sub-unit group The Pin+Numerical Control hydraulic synchronous jacking scheme was implemented, which saved 8 months of time compared with the conventional hoisting scheme on the premise of ensuring driving safety.

It is reported that the roof push of the East Station of Lushan Station will be carried out in three times, and two more pushes will be carried out in mid-July, which will fill the gap in the efficient and safe construction of large-scale station buildings on busy railway lines. Lushan Station is expected to complete the construction of the main structure by the end of December, and will enter the decoration stage in 2024. Editor / Xie Li
