Underground "building blocks", new progress in the second phase of Line 12 is coming!

On August 15th, with the successful prefabricated top board, the No. 12 Phase II project of Shenzhen Municipal Rail Transit Line 12, which was undertaken by China Electric Power, was capped, marking all the nationwide internal support systems under the assembly system of all subway stations in the nationwide support system all the subway stations under all internal support systems. The assembly was completed, and Shenzhen's first full -assembly subway station was successfully capped. It laid the foundation for creating a new generation of prefabricated subway stations with Shenzhen characteristics and leading the application of prefabricated stations.

The prefabricated component uses the "building blocks" to fight

Shapu Station is one of the first seven -seat stations in Shenzhen Metro. The total length is 235 meters and the assembly section is 164 meters long. It consists of 762 prefabricated components. The overall assembly rate reaches 70%.

For the first time, the top board adopts a single -block tank structure, which weighs 128.8 tons, which is the highest weight of single -block components in the nation's subway assembly stations.

The outer frame structure uses the prefabricated component with a width of 1.994 meters to combine the "building blocks", which greatly reduces the number of waterproof seams. The waterproof system of "two pads, one end, one embedded" is used to cancel the full outsourcing waterproof. Essence The internal structure in the later period will also be assembled.

装配式车站具有绿色技术集成、BIM技术集成、智能化集成、标准化集成、工业化生产、装配化施工、信息化管理、一体化精装等特点，有利于节约能源、减少施工污染、提升劳动生产效率和Quality and safety level.

Subway Line 12 Phase II

The backbone route connecting Baoan and Guangming

The second phase of Metro Line 12 is drawn from the East East Station of the first phase of Line 12 project.

The total length of the line is about 8.05km, with 6 stations, and the entire line is set up.

4 stations enter the main structure of the main structure, and the main structure of the station has been completed by 14%;

The shield is open 8.3%.

Shenzhen advanced demonstration has formulated the quality standards of prefabricated and assembly at all stages of prefabricated subway stations, and studied the unique disassembly and replacement of Shenzhen characteristic prefabricated stations to support the construction process of the ring, leading the industry standards, and becoming the industry's "textbooks".
