A deep tunnel project to drain rain water at Dubai South’s Airport City and Expo 2020 will be complete in time for the start of the six-month exhibition in October next year, Dubai Municipality has confirmed.
The $680million 10.5km long tunnel will serve an area spanning 490km.
Eng Fahd Al Awadhi, director of the drainage projects department at Dubai Municipality, said one of the drilling machines had reached Sheikh Zayed Road's 8th Intersection, where it would be extracted, dismantled, and reassembled to move to the 7th Intersection.
The final stage of drilling of the tunnel will begin at the 7th Interchange and reach the tunnel's pumping station, located within reclaimed land across Dubai World Ports. This stage is due for completion by early-2020.
Al Awadhi added: “The work continues on two tasks – the first tunnel, which has reached about 4.5km so far, and the second task, which includes the construction of the main pumping station – in a parallel system.
"The three final foundation stages will see the use of about 55,000 cement pieces in the tunnel, each weighing two tons, along with the installation of 4,400 huge metal rings, ensuring the immunity and strength of the deep tunnel.”
