Abu dhabi super tunnel

September 7, - The construction of the Abu Dhabi Deep Sewer Tunnel, one of the deepest gravity tunnels in the world, as explored in a documentary by National Geographic. STEP oversaw the construction of a tunnel about 40 kilometres long in order to collect the waste waters of the island and mainland of Abu Dhabi by means of gravity, and direct them to a treatment plant in Al Wathba. Salini Impregilo took part in the project, working on two of the three lots T and T awarded to contractors. It drilled a tunnel of 25 kilometres with an excavation diameter of about seven metres, and 10 access shafts with depths varying between 40 and 80 metres. The Group used sophisticated, mechanised excavation technology never previously deployed in Abu Dhabi. The project was particularly complex from a technical and organisational point of view because it involved the simultaneous use of five Tunnel Boring Machines TBMs at earth pressure. As they excavated, the TBMs simultaneously coated the tunnel with prefabricated concrete. Both the hydraulic tunnel as well as the access shafts were covered with a special membrane to protect the concrete structures from the aggressive environment, enabling them to endure for at least years. Once again, a special documentary gives testimony to the kind of projects pursued by the Group throughout the world: grand, distinctive and technologically advanced. I, the undersigned, state that I have viewed the webuildgroup. Our Projects.

The construction activities started in with the prequalification process commencing earlier in August Countries: UAE. Abu Dhabi's population has exploded in recent decades.

This film follows a team of engineers in Abu Dhabi they race to build a massive sewer system right beneath the city streets, as the current network has reached its bursting point. Abu Dhabi's population has exploded in recent decades. But beneath the city trouble is brewing. Abu Dhabi's sewer network - built thirty years ago to service the needs of a small town - has reached bursting point. It's running beyond capacity and can no longer cope with the growth above.

This film follows a team of larger than life engineers and construction workers locked in a race against time to build a replacement sewer beneath the city. Advertise with us. The Group used sophisticated, mechanised excavation technology never previously deployed in Abu Dhabi. The connecting sewers or link sewers will overall enable the city to do away with 35 existing pumping stations which are on the verge of finishing their useful life. The current project forms a crucial part of Plan Abu Dhabi , which is a comprehensive plan of developing Abu Dhabi to accommodate the increasing population in the city, which is anticipated to reach three million by As of February , 33km of the overall 41km of the tunnel has been tunnelled. Project Type Hydraulic wastewater network tunnel. The company will also supply more than 40km of jacking pipes with internal diameters ranging from mm to 3,mm, including several access shaft segments for the link sewers.
