Shijiazhuang Metro Line 2 Phase II engineering Dongshangze Station-Toyo Station Division Right Shield Starting

At 9 o'clock on July 15th, Shijiazhuang Metro Line 1 of the second phase of the northern part of the Northern Section of the Northern Section of the East of the East-Toyo Station Division of Toyo Station was successfully launched. This is the first after the start of the first shield on June 18 The start of the two shields also marks the stage of tunnels in the interval.

The second phase of the northern part of Line 1 is Fuze Station (excluding) -onoya Station and Nanniu Parking Lot Project. Construction started in December 2021. The current construction projects mainly include Dongshangze Station-Toyo Station interval, Toyo Station, Toyo Station-Nanniu Parking Lot in and out, and Nanniu Parking Lot. Connected to open to traffic.

Dongshangze Station, Toyo Station, Dongshangze Station-Toyo Station interval and interval wind well projects are all undertaken by the 18th Bureau of the China Railway. Liu Jinzhong, the person in charge of the project project, introduced that the left-line shield of Dongshangze Station-Toyo Station interval at the beginning of June has been excavated for 128 meters, and the construction status is good. Usawa Station digs to Toyo Station. The project department has achieved dual -line offering in less than a month. In order to ensure the safe, smooth and efficient tunnel of the shield machine, all management and technical personnel carefully scientifically organized, optimized the construction plan, strictly controlled each process, and strictly controlled the control of each process. , Strengthen on -site monitoring information linkage, follow up the equipment inspection and follow up, and make full efforts to ensure safety and quality while speeding up the construction progress.

It is reported that the Toyo-Toyo Station interval tunnel starts from the east of Shangze Station and is laid from the south to north. Fine sand layer and powder clay layer. The distance between the distance is long, the slope is large, the curve radius is small, and the sand layer is the main. The risk of knife, knife discore, surface settlement, pipeline destruction, and sand in the dug of the shield machine during the excavation process.

At the same time as the dual -line shield is excavated, the northern part of Line 1 is advancing at full speed. As of now, in addition to the opening of the tunnel construction of Dongshangze Station-Toyo Station, Toyo Station, Dongshangze Station-Toyo Station Division Windyou and other projects have also entered the main structure of the main structure. The interval wind well has completed the concrete pouring of the deep -founded pit bottom plate.
