The electricity is on, the station is on, and the first phase of the Sichuan line of the subway is closer to traffic.

July 31st

Wuhan Metro Qianchuan Line Phase I

A successful test of contact rails throughout the line

It is marked that all the equipment of the power supply system of the line is successful

It means that the train can be charged to debug and test running

It also means

It's a big step away from the goal of opening to traffic

Qianchuan Line Phase I

Extension from the North Station of Line 7

Along the way pass through Matsui Station, Tang Yunhai Station,

Dragon Avenue Station, Tenglong Avenue Station,

Tianyang Road Station, Linkong North Road Station,

Hengdian Station and other 7 stations

The first phase of the Okawa Line is a schematic diagram.

Refined construction with national excellent standards

In accordance with the national excellence standards, the project department has achieved the results of the quality improvement of 7 processes in innovation.

The first time the bridge telescopic joints of the elevated section are installed, the sunshade retractable section is used to reduce the deformation of the sunshade caused by thermal expansion and contraction, which increases the safety and stability of the cable operation; , Ensure the horizontal degree and regulating gap value of the base installation, and enhance the accuracy of derailed installation.

The new technology of the Sichuan Line in the Wuhan Metro is not only there. At the end of March, it also used this technology for the first time →

The construction personnel check the contact rail within the interval.

At the same time, the BIM modeling technology is used to digitize and picture the standards of each process in detail. The image intuitively guides and standardize the on -site construction process to ensure that one time is formed and one time.

90 sunroofs ““ “‍ ‍ ‍ ‍

The first phase of the Qianchuan Line has two cable connection construction, and the power supply is introduced from the Songjiagang owner of Line 2 and the North Station of Line 7, respectively. After the construction requires the operation and revenue on the day of Line 2 and Line 7 and stop the power supply in the interval, the construction staff uses it at 00:00 to 3:30 am.

Engineers performed electricity delivery in the intermediate pressure and DC switch cabinet.

During the 3 -month sunroof point construction, the project department was linked to fight, and the key tasks of the day, Zhou and Months were detailed and decomposed, and the pins were sewed, and the key points, difficulties, and nodes were shown.

"Electric Tong" is an important milestone node for the construction of the subway. As the first phase of the Qianchuan Line is "light up", the power consumption required for the project has been changed from the previous temporary power consumption to the formal power, which also means that all the cars in this line Equipment systems such as signal, power lighting, ventilation, water supply drainage, escalators, and automatic ticket machines will continue to enter the stage of electrical debugging and achieve functional stage.

"Electric Tong" will also provide continuous power support for the cold, hot, comprehensive joint and trial operation of subway trains.
