TIANDI 2 EPB TBM in Tianjin Metro line 2 project

Tianjin Metro line 2 tunnel boring project

The name of this project is: The construction of No.2 contract in the project of Tianjin Metro line 2, constructed by The fifth construction corporation of ChinaCoal.

 The Project begins form West YanAn road station to West JieYuan road station. Time limit for the project is from March 2010 to October 2010.

Geological conditions:

The area along the Tianjin Metro line 2 is alluvial plain, which all covered by Cenozoic sediments, most condition is Continental deposit.

Affected by the transgression and regression in Late Quaternary Period, sedimentary layer have been formed on the mutual area of ocean and land.

The thickness and position of sedimentary layer are different along the Metro line, but obvious regularity for cause of formation can be found.
