China's First Fully Assembled Metro Station in Karst Development Area Successfully Completed

On May 15, with the assembly of the last 128.8-ton prefabricated component roof in place, Fukeng Station of Shenzhen Metro Line 16 Phase II Project of China Railway 14th Bureau completed the assembly, marking the successful completion of the assembly of the first fully assembled metro station in karst development area in China. On the same day, the "Xing'an No.2" shield machine on the right line of the section from yuanshan Station to Longxing Station started smoothly.

has been completed

. Fukeng Station, constructed by the 14th Bureau of China Railway, is one of the three fabricated stations in the second phase of Shenzhen Metro Line 16. The total length of the station is 228 meters, and the overall assembly rate is 76.3%. It is formed by 435 "building blocks" assembled in sequence on site. It is the first batch of assembly type pilot metro stations in Guangdong-Hong Kong-Macao Greater Bay Area, and also the first batch of fully assembled metro stations with large prefabricated components under the internal support system in China.

Fukeng Station is located in the karst development area of Shenzhen City, with a total karst rate of 8.34%, a hole rate of 70%, a maximum single karst cave height of 10.6 meters, a cave volume of nearly 4000 cubic meters, and abundant fissure karst water. Under such geological conditions, the excavation of the foundation pit of the station has a high risk, which puts forward higher requirements for assembly.

In order to complete the assembly construction safely and with high quality, according to the construction characteristics of karst development area, the project department vigorously promotes the construction of "intelligent + information + digital" intelligent manufacturing platform, through the application of BIM model visualization system and other technologies. It has independently developed a multi-functional "180-ton gantry crane + separated assembly trolley" tooling equipment with rotation, anti-swing, fine-tuning of posture, correction and other functions, which has achieved millimeter-level precision assembly. Compared

with the traditional construction method of subway station, the prefabricated construction technology

of Fukeng Station has greatly improved the construction speed and quality of the project. The "Xing'an No.2" shield machine on the right

line of the section

from yuanshan Station to Longxing Station started

smoothly on the same day, and the "Xing'an No.2" shield machine on the right line of the section from yuanshan Station to Longxing Station started smoothly, marking that the section has entered the stage of double-line synchronous excavation. The stratum conditions of the right line tunnel between yuanshan Station and Longxing Station where the shield machine starts

from yuanshan

Station to Longxing Station are complex and technically difficult. In order to ensure the smooth progress of shield construction, the project team coordinated scientifically, promoted safety production with practical actions, refined management, and strived to complete the follow-up construction tasks with high quality and efficiency.

It is reported that after the completion of the second phase project department of Shenzhen Metro Line 16, the connection between Longgang Central City and yuanshan District will be effectively strengthened, and the economic development along the line will be promoted.
