Tohoku Shinkansen Sanbongihara Tunnel
Received FY2006 Japan Society of Civil Engineers Outstanding Civil Engineering Achievement Award
|Orderer||Japan Railway Construction, Transport and Technology Agency|
|Structure and scale||NATM method, excavation cross-section: 62m²; tunnel length: 1,274m; slurry pressure shield method, shield outer diameter: φ11.4m; finishing internal diameter:φ10.8m; tunnel length: 3,006m|
We were responsible for the construction of a Shinkansen (high-speed rail) tunnel with a total length of 4,280 meters spanning Rokunohe Town, Kamikita Town, and Towada City of Kamikita County, Aomori Prefecture, a light roadbed of 335m and an elevated bridge of 70m.
