The project was implemented by a joint venture of TAISEI-GAMA-NUROL, with total length of line about 13,6 km.<\/p>\n
It is a rail tunnel Project comprises an 1,4 km length immersed tube tunnel under the Bosphorus strait connecting Europe and Asia continents.<\/p>\n
The most advanced tunneling techniques were used for construction of the tunnel: the approximately 1.4 km undersea tunnel was constructed by the immersed tunnel method, and the on-land tunnel was constructed by a combination of the shield tunnel method (constructed by TBM), NATM (New Austrian Tunneling Method), and cut and cover method.<\/p>\n
The deepest part of immersed tube tunnel is 60 m below the sea surface, the world\u2019s deepest. Immersed tube tunnels and the land tunnel is directly connected to each other under the sea, first time in the world. This is required great accuracy and safety to accomplish and deal with the challenges such as complex and rapid tidal currents in the Bosphorus Strait.[\/vc_column_text][vc_column_text]Project Summary:<\/strong><\/p>\n Project Name: <\/strong>Marmaray BC-1 Contract<\/p>\n Client: <\/strong>General Directorate of Railways, Ports and Airports Construction (DLH), Turkish Ministry of Transport<\/p>\n Contractor: <\/strong>Taisei, Gama, Nurol JV<\/p>\n Total length of line: <\/strong>13,6 km<\/p>\n Immersed Tube Tunnel Length: <\/strong>1,4 km<\/p>\n Shield Tunnel Length: <\/strong>9,8 km<\/p>\n Cut & Cover Length: <\/strong>2,4 km<\/p>\n Passenger Capacity: <\/strong>75.000 passenger\/hour\/each direction[\/vc_column_text][vc_separator][vc_tta_accordion][vc_tta_section title=”Temporary Concrete Lining at North & South PF, PFV-S and PFV-L Tunnels” tab_id=”1495792706020-4a1033de-549a”][vc_column_text]The largest arch lining within the scope of Marmaray Project has been applied by Y\u00fcce Yap\u0131.<\/strong><\/p>\n With an inner diameter of 14.73 m circular arch lining, the largest tunnel concrete lining of Marmaray Project was produced by Y\u00fcce Yap\u0131.<\/p>\n Tunnel Length: 28.1 m<\/p>\n Casted Concrete: 1015 m\u00b3<\/p>\n Rebar Assembly: 114.5 tons<\/p>\n Steel Tunnel Formwork: 1223.5 m\u00b2[\/vc_column_text][vc_gallery images=”1832,1833,1834,1835,1836,1837,1838,1839,1840″ css=”.vc_custom_1498128092894{margin-left: -22px !important;}”][\/vc_tta_section][vc_tta_section title=”Arch Concrete Lining of East PFV-L & PFE at South and North Tunnels” tab_id=”1495792706092-5fe3af06-eb78″][vc_column_text]Arch linings of East Shaft at Sirkeci Passenger Platform Tunnels were produced by Y\u00fcce Yap\u0131.<\/p>\n Tunnel length: 42 m<\/p>\n Concrete: 1645 m3<\/p>\n Rebar Assembly: 279 Tons<\/p>\n Wooden Butt Joint Formwork Fabrication: 410 m2[\/vc_column_text][vc_gallery images=”1841,1842,1843,1844″ css=”.vc_custom_1498128147170{margin-left: -22px !important;}”][\/vc_tta_section][vc_tta_section title=”Concrete Lining Works of Escape Shaft, Escape Tunnel, Cross Passage & Inner Structure of Escape Shaft at Sirkeci Station” tab_id=”1495792819305-0e4dfc98-5701″][vc_column_text]Concrete linings and inner structures of Escape Shafts and tunnels at Sirkeci Station were completed by Y\u00fcce Yap\u0131.<\/p>\n Rebar: 252 tons<\/p>\n Steel climbing formwork for shaft lining: 942 m\u00b2<\/p>\n Tunnel Formwork: 20 climbing sequences (length of each set; 4.5 m- Tunnel diameter; 7.2m.)<\/p>\n Concrete: 2865 m3<\/p>\n INNER STRUCTURE:<\/p>\n Climbing formwork: 920.6 m2<\/p>\n Concrete: 184.1 m3<\/p>\n Rebar:\u00a0\u00a0 20.26 tons<\/p>\n Formwork: 214.1 m2<\/p>\n Concrete: 39 m3<\/p>\n Rebar: 4.59 tons[\/vc_column_text][vc_gallery images=”1845,1846,1847,1848,1849,1850,1851,1852,1853,1854,1855,1856,1857,1858,1859,1860,1861″ css=”.vc_custom_1498128311122{margin-left: -22px !important;}”][\/vc_tta_section][vc_tta_section title=”Construction of East and West Ventilation Shaft Transformer Building” tab_id=”1495792862969-3e2882f8-88fc”][vc_column_text]East and West Ventilation Shaft Transformer Buildings were constructed by Y\u00fcce Yap\u0131. <\/strong><\/p>\n Within this scope, 56.06 tons rebar, 1731 m2 formwork and 544 m3 concrete fabrication was carried out, and Y\u00fcce Yap\u0131 also completed all isolation, backfilling and finishing works of the project.[\/vc_column_text][vc_gallery images=”1862,1863,1864,1865,1866,1867,1868,1869,1870,1871,1872,1873″ css=”.vc_custom_1498128425086{margin-left: -22px !important;}”][\/vc_tta_section][vc_tta_section title=”Construction of East& West Ventilation Slab” tab_id=”1495792897617-106673db-109f”][vc_column_text]West Ventilation Slab was constructed by Y\u00fcce Yap\u0131.
