Dubai Deep Tunnel Storm Water System Project

CREG designed and manufactured two Ø11.05m EPB TBMs for DS233/2 Deep Tunnel Storm Water System in Dubai, UAE, which is to serve World Expo 2020. The tunnel, 10,426m in length, is the main tunnel of the whole flood and stormwater discharge system, and will pass through sandstone and mudstone strata. These two TBMs celebrated FAT in Guangdong, China on July 11, 2018.
The project is being constructed by a joint venture of Porr and Six Construct. It is scheduled to be finished ahead of Expo 2020 Dubai, in October of that year. A total of more than 600 international experts are currently involved in the project. 

The tunnel will be driven through the Barzaman and Fars formations. The Barzaman formation consists of conglomerate, calcisiltite and calcilutite and the Fars formation consists mostly of mudstone and calcilutite.
