Here comes the latest news from Shenyang Metro Line 6!

The initial support for the concealed-digging section between Shifuyingyiyuan Station and Dananbianmen Station was completed.

On June 25, with the final steel grille concrete spraying, the initial support for the concealed-digging section between Shifuyingyiyuan Station and Dananbianmen Station of Shenyang Metro Line 6 Bid Section 10, constructed by China Coal Third Construction Company, was successfully completed. This marks the commencement of the second lining construction stage for the tunnel engineering.

The right tunnel of the section between Shifuyingyiyuan Station and Dananbianmen Station is about 440 meters long in total, while the total length of the left tunnel is about 442 meters. The tunnel structure comprises a total of 7 types of cross-section forms such as standard cross-section, jet fan section and civil defense cross-section. The construction side has adopted various construction methods to ensure the safe completion of the concealed-digging tunnel.

The minimum clear distance between the two tunnels of the section between Shifuyingyiyuan Station and Dananbianmen Station is only 0.85 meters. Radial grouting has been employed during construction to reinforce the stratum of tunnels, thereby ensuring the stability of excavated soil. Initial support and second lining have been adopted simultaneously in the large cross-section construction to significantly reduce the construction period.
