The Pearl River Estuary Tunnel of Shenzhen-Jiangmen Railway

The 13.69km Pearl River Estuary Tunnel of Shen-zhen-Jiangmen Railway is located in the Pearl River estuary between Guangzhou and Dongguan, which is the key project of the whole line of the Shen-zhen-Jiangmen Railway and the ratio of bridges and tunnels is 98%.

Project Features

Face challenges as long distance TBM tunnelling, great depth, high water pressure, complex geological conditions, and construction environ-ment Hazards.

With the deepest part of the tunnel being 115m below water and the maximum water pressure as high as 1.06MPa, it is the world's deepest undersea tunnel.

Tunnelling in mix-ground highly demands on shield tunnelling technology.

The implementation of a fully prefabricated assembly process has significantly reduced the risk of personnel safety control, accelerated the construction schedule, achieved green construc-tion and effectively improved the level of construction of the tunnel's internal structure.
