At 9:00 am on the morning of September 15th, with the "Victory No. 1" shield machine on the first phase of the project Huzhuang Station, the first phase of the Line 12 of Zhengzhou Rail Transit Line, it marks the 12 of the 12 major sources of risk. The entire line of the number of the number line has achieved a "hole", which has laid a solid foundation for the smooth implementation of the subsequent work.

It is understood that the project is the L -shaped direction of north -south -east -west, with a total length of 17.034 kilometers. Construction started in June 2020, wearing 8 levels and 31 Ⅱ risk sources such as high -level bridges, railways, high -speed rail, rivers, and existing subway lines. Tunnel construction.

During the dug -in of the shield, the participating units firmly established the concept of "fine demonstration subway", and strived to prevent fine prevention and quality management. Implement risk sources of grading control, prepare special safety plans, and pay close attention to on -site safety control. Adhere to standardized management, uniformly planned from the construction site to the construction site, and the tunnel interval is beautiful. Adhere to normalization of dust monitoring and governance, implement the "eight 100 %" measures, implement centralized steel bars, and the image of a benchmark site for civilized construction. Establish a shield remote command center to create smart digital construction sites, and the shields dig into various parameters, etc., are within the controllable range. Actively improve the construction method and create a precedent for the construction of mechanical laws in the urban rail shield interval in the Central Plains.

The first phase of the Zhengzhou Rail Transit Line 12 is the rail transit line of the Zhengzhou Economic and Technological Development Zone and the Zhengdong New Area, which can effectively alleviate the traffic pressure of the Economic and Technological Development Zone and Zhengdong New District after completion. The northern area of ​​the Economic Development Zone has been upgraded and renovated, strengthening the traffic connection between Nancao District, Baisha Group and Green Bo Group, and promoting regional economic coordinated development is of great significance.

At present, the main structure of 11 stations on the entire line has been capped, and it is comprehensively promoting the construction, rail installation, Feng Shui power installation and decoration projects.
