Gürpınar and Çanta Wastewater Tunnels Construction (Gürpınar-Çanta / İstanbul)
Scope of Work; Wastewater Tunnel with 6015,59 m length Ø2000 mm external diameter, 6 main tunnel shafts with 7,50 m. internal diameter
Administration: İstanbul Metropolitan Municipality, İSKİ İstanbul Water and Sewerage Administration
Constructor: Özka Kalyon Wastewater Ordinary Partnership
Within the project scope that will implemented by transporting the wastewater to wastewater treatment unit which will be gathered at İstanbul Gürpınar and Çanta region’s basins, hydraulic calculations will be made according to the wastewater basin at the region, wastewater tunnel basin plan, route plan and longitudinal section of tunnel will be designed. By evaluating geological data all along the tunnel route, geotechnical engineering models related to the tunnel designing will be designed. In the light of these data, according to the tunnel excavation and construction techniques by Tunnel Boring Machine, engineering calculations of the tunnel precast segment will be made and precast segment lining projects will be designed. Moreover, within the project scope, excavation, architectural and reinforced concrete projects of 6 main tunnel shafts were designed.
