Pioneering the underground three-layer integrated assembly system: In order to achieve the goal of “installing as much as possible”, China Railway Fourth Academy collaborates with various disciplines to conduct research on functional modularization and dimensional modularization, making the assembly scheme applicable to stations of different types, spans, and heights, breaking through the constraints of single component size and low adaptability of assembly stations.

For the first time in China, an underground three-layer integrated precast station has been realized, expanding the application scenarios of precast technology.
