Hangzhou metro line 8 qingpeng road station to yipengdong second road station left line shield section successfully completed

On November 10, with a roar, the blade plate of the shield machine slowly broke through the wall, and the shield section of the left line from qingpeng road station to yipengdong second road station of hangzhou metro line 8 appeared in front of everyone, becoming the first shield tunnel across the whole line!

The first phase of hangzhou metro line 8 is 17.1 km long, with 9 stations, including wenhai road station, qiaotou station, hezhuang station, hejing road station, qingliu road station, qingpeng road station, yipengdong second road station and xinwan road station. A new bay vehicle base.
