New Dubai drainage system to take shape from December 2018
Region’s largest drilling machine for the project receives its finishing touches in Guangzhou, China
The Deep Tunnel Storm Water System project for Dubai’s Airport City Expo 2020 is set to take shape from Q4 2018.
A delegation from Dubai Municipality headed by its Director General, Dawood Al Hajiri visited the Chinese city of Guangzhou to learn about the stages of manufacturing of the drilling machine.
The drilling machine is expected to arrive at the site in October 2018 and excavation will begin in December.
The project will cover an area of 490 km2, which is almost 40% of the entire urban area of Dubai.
The project was launched in October last year and is due to be completed by September 2020, as Dubai Municipality said its “racing to complete the project before the World Expo set to be held in 2020”.
The city is set to purchase two large TBM machines for drilling deep tunnels for this project.
The municipality said these machines will be the largest in the region used for digging tunnels that will be used for transporting storm water.
Al Hajiri said: “TBM 1 will begin its drilling work from the starting of the seventh intersection on Sheikh Zayed Road for a distance of 2.4 km towards the sea up to the location of the main pumping station. It will then be dismantled and reassembled to move from the seventh intersection until the eighth intersection along 1.7 km.”
The manufacturing and installation of one drainage system will take 364,000 man-hours, and the daily energy consumption of the first device will be 64 MW taking the total consumption in 12 months to approximately 20,156 MWh.
The second device will have a daily electricity consumption of 58.738 MW taking the total consumption in 14 months to 21,380 MWh.
He pointed out that the finished internal diameter of the tunnel will be 10 meters.
