Zhengzhou metro line 3 has been put into operation at the end of this year

May 28, zhengzhou rail transit line 3 project ushered in phased progress. The section between the shuncheng street station and the jialu river parking lot of line 3 has realized the single-track rail connection on May 25, laying a solid foundation for the next stage of "all-line rail connection". According to the plan, rail transit line 3 will be opened to the public at the end of December.

As a key livelihood project, zhengzhou rail transit line 3, phase I project, is the first rail transit PPP project cooperated by China construction and zhuhai. The line is 25.5 kilometers long, with 21 stations, running through the main axis of zhengzhou's east-west development from the northwest to the southeast. After the opening of the line, it will promote the formation of the overall framework of zhengzhou city rail network, which is of great significance for speeding up the construction of modern comprehensive transportation in zhengzhou city.

The first phase of line 3 is full system mechanical and electrical engineering, weak current and other intelligent engineering, decoration and decoration engineering, part of the conventional mechanical and electrical engineering, the track laying task of the main line and the parking lot. After working day and night, the team completed the task of "short rail connection" of line 3 5 days ahead of schedule. It is expected to realize full rail connection on June 20, dentsu on June 30, and hot sliding test on the whole line on July 15.

Compared with the traditional subway construction, the construction of zhengzhou rail line 3 mainly adopts several innovative technologies such as intelligent site management, saving one month's construction time. "Advanced intelligent management technology not only ensures safe production and high quality, but also greatly improves work efficiency."

According to the project construction plan, on September 15, rail transit line 3 will realize no-load trial operation, and at the end of December, it will face the society in the initial stage of operation.
