VIII. World's first case of large-tube water tunnels traversing under subway – the Buried Culvert Project in the 4th Ring Road of Beijing (central route)

The Buried Culvert Project in the 4th Ring Road of Beijing (central route) has two pressurized water tunnels with the inner diameter of four meters, which traverse under Beijing's Wukesong Subway Station. It was the world's first case of large-tube water tunnels traversing under a running subway. The nearest distance between the buried culvert and the subway is only 3.67 meters, while the largest settlement of the subway is merely three millimeters.
