Project of the Year (between €50M and €500M)
Large-diameter shield tunnel engineering project in karst strata of sea area
As a full-line control project of Dalian Metro Line 5, the large shield tunneling project between the railway station and the Barracuda Bay South Railway Station is the key to breaking the barrier of the bay from Qingniwa, Barracuda Bay and even Ganjingzi old district. The 30-minute travel time on both sides of the gulf has been shortened to less than 3 minutes, thanks to this tunnel.
With a total length of 2,882m, this tunnel construction
has many positives impacts. In line with the development direction of the national urban rail transit construction, the tunnel improves the industry's complex stratum shield manufacturing and construction technical capabilities The tunnel on the sea-crossing section of Dalian Metro Line 5 traverses the karst development area.
