Hohhot rail transit line 2 phase I project left short track smoothly through

On December 20, with the completion of the laying of the last pair of tracks on the left side of the water park station to nuo wo mulle station, the first phase of the Hohhot urban mass transit line 2 project under the general contract of China railway construction group and the construction of China railway 16th bureau group was completed.

Hohhot urban rail transit line 2 is the north-south "L" backbone line of the metropolitan area, starting from zhongyou hulian residential area in saihan district in the south and hongsheng industrial park in the north, connecting the main center of the city, the eastern sub-center, the white tower cluster, the southern sub-center and other key areas. The first phase of line 2 is 27.3km in length, all of which are underground sections. There are 24 stations (6 transfer stations), all of which are underground stations, with an average station spacing of 1.168km. Set up a parking lot at the north side of tuli east road station in xincheng district and a car depot at xilamaying village in saihan district.

After laying construction approach, focus on operation over, from 2017 in early November, planning in advance, the 2018 complete construction preparation, using "small gaps, step-by-step" construction tactics, successfully completed a frantic jumble track-laying ballast car depot, parking lot, 2019 years after entering underground without a frantic jumble track-laying ballast, all the builders positive opening operation of line 2, initiative, active coordination, the initiative as, grasped the nettle and conditional on creating it, no conditions, with only 6 months can finish tully, parking lot, car depot lama camp without a frantic jumble of track-laying ballast two base construction tasks. In the construction interval between the most difficult wuliying station and Inner Mongolia stadium station, I took the initiative to make changes and creatively used the central flowering tactics. I made use of the shield well to lay the material off the track in the west street of the university, and successfully broke through the closure of the operation surface. It only took 4 months to complete the short track.

By the end of the day, the track paving achievement is good, the track paving construction has completed 98% of the total, is to double track through the goal of sprint. The realization of the "rail pass" on the left line and the formal mechanical and electrical installation on all the lines in hushi have created favorable conditions for the joint debugging and testing and laid a solid foundation for ensuring the initial operation of nodes.
