The reporter learned from the Guangzhou Metro on July 25 that recently, after the efforts of the Guangzhou Metro builders, the second phase of Line 13 Tianhe Park Station, Zhucun Station, E41 Shield Well to Tangxia, Rainbow Bridge to Memorial Hall range range The projects have successfully completed the established project target node task, creating favorable conditions for the construction of the next stage of the line.

Tianhe Park Station Tunnel is safe "through lake"

According to reports, Tianhe Park Station's secret digging linked line is located in Tianhe Park. From the north, the subway Line 11 Tianhe Park to Huajing Road Division section, laid it along the south of the east. Return the back of the park. The width of the tunnel excavation contour is 6.8 meters, the height is 6.95 meters, and the total length is about 437.5 meters. Among them, the lake section is 131.7 meters long. In order to reduce the impact of subway construction on the water body of the park, the tunnel has abandoned the construction of the original plan of the original plan, and the construction of the dark digging method is changed.

In order to wear the lake area safely and efficiently, the project management team of the China Railway Third Bureau of the Guangzhou Metro and the construction unit has successfully overcome the risks 23 days in advance after 402 days of fighting, and realize the secret digging of the Lake Tunnel through the dug and connection line of Tianhe Park Station.

Zhucun Station Dark Digging Tunnel Complex Connect

Zhucun Station is located on the west side of the intersection of Zhongshan Avenue and forest roads in Tianhe District. The total length of the station is 223.2 meters. It is the underground light and dark excavation separation island stations. In order to minimize the impact on the main roads of Zhongshan Avenue, the main body of Zhucun Station uses the left and right lines to separate the excavation plan, avoiding the foundation of cross -line bridge piles on the middle of Zhongshan Avenue, and improving construction safety and operating efficiency.

Faced with many difficulties in the urban construction environment, difficulty in traffic guidance, deep digging foundation pit, cumbersome digging processes, and complicated geological weakness, the construction management team of the Guangzhou Railway Fifth Bureau in Guangzhou and the construction unit adopted a variety of measures to promote safety production. In the end, all the excavation tasks of the six dark traversal channels of the station and 1 rail -top ventilation were successfully completed. It marked that the station's dark tunnel was fully penetrated and officially entered the secondary lining construction stage.

Realize dual -line penetration between the two sections

As the "Capital" shield machine slowly breaks the wall, the E41 Shield Well to Tangxia Shield range smoothly realizes dual -line penetration. The shield range is about 1029 meters in length. The "crossing" departs from Tianhe Park and travels along Zhongshan Avenue. The safety risk is high and the construction is difficult. In order to ensure the safety of construction, the subway builders of the China Railway Eighth Bureau of Guangzhou and the construction unit carried out a survey and risk assessment of the construction status of construction along the line, formulated special construction plans and emergency treatment measures, and successfully completed the dual -line construction tasks of the shield interval.

At the same time, the construction task was also the "Yue Sheng" shield machine. It officially arrived at the Memorial Hall Station after Ping An's 668 ring.

Up to now, the No. 3 Phase II (Chaoyang-Fish Bead) of Guangzhou Metro Line 13 has completed a total of 53%. Of the 23 stations, 5 were capped, 17 were construction for civil construction, and 1 station was prepared for preliminary preparations. Among the 23 interval, the entry and exit lines of the five intervals and the Huihuang parking lot have been connected. 13 of them are carried out in civil construction, and the remaining 5 are prepared for preliminary preparations. Fish Parking Lot, Phoenix Parking Lot and Cover for civil construction.
