The four shield tunnel between stations and one station part shield tunnel (triple multiface shield) were constructed between Suitengumae and Oshiage stations of the Teito Rapid Transit Authority No.11 Line (Hanzomon line).
In consideration of the equipment installation space of character of soil for excaved, and start base, slurry and slurry-earth-pressure shield driving method were adopted.
Since it became excavation of adoption of the first slurry-earth-pressure shield in a corporation, construction of the single track parallel shield by slurry and slurry-earth-pressure, and a soft ground, while performing measurement of ground deformation in the initial drivesection of each shield and determining the suitable control values, the construction actual result of a large-section shields were accumulated.
