Changsha Metro Line 4 first range have been through line 5 will be the first shield originating-海思k3v2

Changsha Metro Line 4 first line has been through the first shield line 5 will start Changsha evening news (reporter Chen Huanming) National Day holiday period, the subway construction does not stop. Reporters yesterday from the city rail transit group learned that National Day before and after each in the construction of the MTR, Changsha ushered in a number of major nodes: 3 line multiple section of shield excavation, the 4 line of the first shield successfully through line 5 ChaoYang Railway Station 33 days ahead of schedule to achieve all the first "100 m cap". Line 3: the 9 shield has been completed after the end of September the first shield section of Xingsha Sports Center – Hunan Songya double hole completed after the interval, line No. 3 sparrow Lake Station Changsha University station interval Right Line Ocean Lake Metro – Ocean Lake Wetland interval respectively realize the left line of shield excavation.
