Demolition of the encirclement in advance and returning the road to the people Chengdu Metro Line 4 will be opened in February next year.

Yesterday, good news came from the construction site of Metro Line 4. In order to speed up the overall construction progress of the line and shorten the time of occupying the road and surrounding the city as much as possible, the actual construction progress of each station under construction is planned one month in advance on average, and the opening time of the tunnel is advanced to February of the following year. At the same time, the technical schemes of subway stations such as qingjiang road station, Taisheng Road Station and Provincial Federation of Literary and Art Circles Station have been adjusted, which means that road traffic such as Qingyang Avenue, Frozen Evergreen Tree and Wucheng Street will resume several months in advance, return the road to the people and ease the traffic pressure in urban areas.

Yesterday morning, dozens of construction workers were busy at the construction site of Wen Jia Station of Metro Line 4 on the north side of the second section of Guanghua Avenue. Since the enclosure construction began in February, the station has completed the earthwork construction and entered the construction stage of the main structure of the station. According to the construction progress, the main structure of the station will be capped at the beginning of 10, which will be 6 months ahead of the original construction period. ? Due to the early completion of the main body, it provides conditions for the shield to go down the well. The shield machine can be launched around the end of August, which is also four months ahead of schedule. ? Xu Shaoping, overall head of Wen Jia Station of China Railway 13th Bureau, said.

Point 1

Restore the original traffic on Qingyang Avenue at the end of April next year.

According to Jiang, deputy director of Engineering Department I of Chengdu Metro Construction Company, the construction time of the original main structure of qingjiang road station at the intersection of Qingjiang Middle Road and Qingyang Avenue is from July 3 this year to September 30 next year. By adjusting the construction method, the intersection node cover excavation method is optimized as cut and cover construction for quickly laying temporary steel temporary bridge, and the three-time edge-reversing construction process is optimized as two-time edge-reversing construction, which ensures the two-way six-lane traffic of Qingyang Avenue at the intersection. The time for the intersection to occupy the road is 4 months ahead of schedule, and the original traffic of Qingyang Avenue will be restored at the end of April next year. At the same time, in the later period, the open-cut and reverse-edge construction of the north side subsidiary structure crossing the road was changed to the underground excavation construction, which reduced the occupation of the middle road of Qingjiang Middle Road, and the original two-way traffic of Qingjiang Middle Road could be fully restored by the end of August next year.

Second point

The traffic of frozen green trees has been restored, and the traffic of Shi Yang Street is expected to be optimized in advance.

The reporter learned that the original preliminary design plan of Taisheng Road Station set up shield starting wells and track row wells at the intersection of Frozen Qingshu and Zhonglisi East Road. As the starting point of the shield, the frozen Qingshu Street and Zhonglisi East Street must be closed for nearly two years. In order to ensure the rapid construction of the shield section and avoid the traffic jam of the frozen Qingshu Street and Zhongliesi East Street, the starting shaft of the shield was adjusted to Taisheng Road Station for initial shield excavation, and the traffic of Zhongliesi East Road, the frozen Qingshu Street, Yuefu Street and Xiawa North First Street was restored 22 months in advance (from 201April to 201February).

In addition, according to the specific situation of the corresponding station construction, the subway company has been organizing and studying the scheme of adjusting the shield departure of Shi Yang Street to the station departure. If the scheme is feasible, the one-way traffic condition of Shi Yang Street will be optimized to two-way four lanes more than 12 months in advance.
